Description
Technical field
The present invention relates to antibacterial type swivel chair synthetic leather and preparation method thereof.
Background technique
With the continuous development of society, living standards of the people increasingly improve, and requirement of the people for living environment is also increasingly
It improves.Currently, swivel chair is not moisture resistance with synthetic leather, light fugitive, cracky, it is difficult to reach high-grade decorative effect.For natural leather,
Due to being restricted by natural conditions, while the consciousness of protection animal is gradually reinforced in the whole world, and natural leather is reduced year by year.
Currently, the antibacterial type swivel chair synthetic leather developed in the market, generally comprises surface layer and bottom, surface layer is generally mixed by polyvinyl chloride resin
It closes various modifying agent to be kneaded, and bottom is generally fibrous layer, still, such synthetic leather gas permeability is bad, wear no resistance,
Anti-corrosion acid-proof performance is poor, feel is not soft, and bottom and surface layer are easy to be corroded and divided in hot humid environment.On
The biocidal property for the swivel chair synthetic leather stated is also bad, and for antibacterial problem, it is antibacterial to be promoted that some companies can be added bacteriostatic agent,
But after washing repeatedly, the fungistatic effect of swivel chair synthetic leather, which will appear, sharply to be declined.
Summary of the invention
In view of the deficiencies of the prior art mentioned above, problems solved by the invention are as follows: provide a kind of by repeatedly washing it
It has been able to maintain the antibacterial type swivel chair synthetic leather of fungistatic effect afterwards.
To solve the above problems, the technical solution adopted by the present invention is as follows:
A kind of antibacterial type swivel chair synthetic leather, including bottom and surface layer；The surface layer is fitted in the two sides of bottom；It is described
Surface layer comprise the following components in parts by weight: 100 parts of polyvinyl chloride resin, 50 to 60 parts of plasticizer, 20 to 30 parts of aramid fiber, silk
20 to 30 parts of fiber, 5 to 10 parts of ramee, 10 to 20 parts of cotton fiber, 5 to 10 parts of foaming agent；The bottom includes following
The component of parts by weight: 100 parts of polyvinyl chloride resin, 30 to 40 parts of calcium carbonate, 5 to 10 parts of stabilizer, 5 to 10 parts of polytetrafluoroethylene (PTFE).
Further, the ratio of the cotton fiber and ramee is 2.
Further, aramid fiber and silk fiber weight fraction ratio are 0.8 to 1.2 in the surface layer.
Further, aramid fiber and silk fiber weight fraction ratio are 1 in the surface layer.
Further, the polytetrafluoroethylene (PTFE) parts by weight are 6 to 8 parts.
The preparation method of one antibacterial type swivel chair synthetic leather, steps are as follows:
(1) preparation of bottom:
A, each component of bottom is stirred mixing according to parts by weight in blender；
B, mixed material is kneaded, mill, calendering, obtains bottom；
(2) preparation of surface layer:
A, according to parts by weight in the mixture of aramid fiber and silk fiber plus water, be then placed in pulper carry out it is broken
Solution, obtains mixed slurry；Then mixed slurry is sent into beater and is beaten, obtain free shape fiber pulp；It finally will trip
From shape fiber pulp by squeezing, drying, stand-by dry mixed fiber pulp is obtained；
B, ramee and cotton fiber are mixed according to parts by weight, in the mixture plus water, is then placed in pulper
Middle carry out size degradation, obtains antibacterial mixed slurry；Then antibacterial mixed slurry is sent into beater and is beaten, obtain free shape
Bacteriostatic fiber slurry；Finally free shape bacteriostatic fiber is starched by squeezing, drying, obtains the antibacterial composite fibre slurry of stand-by drying；
C, dry mixed fiber pulp, dry antibacterial composite fibre slurry, polyvinyl chloride resin, plasticizer, foaming agent are sent into rabble furnace
Middle carry out heating stirring；
D, the mixed material being sufficiently stirred in C is kneaded, mill, calendering, obtains surface layer；
(3) hot pressing is compound:
By bottom and surface layer as on compounding machine, by preheating, flattening, fitting, cooling process, synthetic leather is obtained.
Further, the mixing time in the step a of the bottom preparation is controlled 40 to 50min.
Further, in the step A and step B of the preparation of the surface layer, the beating degree of beater is 65 to 70 ° of SR, mashing
Time is 30 to 40min.
Further, mixing time is 20 to 30min in the step B of the preparation of the surface layer, controlled at 140 to 160
℃。
Beneficial effects of the present invention
Ramee and cotton fiber is added in the present invention in surface layer, since ramee top is pointed, there is prodding and itching feeling,
So it is not used in swivel chair synthetic leather generally, but ramee is also able to maintain very high biocidal property after multiple washing
Can, by cotton fiber and the reasonable ratio setting of ramee, the prodding and itching feeling of ramee can be eliminated, increase the softness of surface layer
Comfort level.The present invention is mixed with two kinds of specialty fibers in the polyvinyl chloride resin of surface layer, and aramid fiber intensity is high, acidproof corrosion-resistant；Silkworm
Silk fiber moisture absorption, scattered wet performance are good, and gassiness, permeability are strong, and smooth surface is uniform, bright and clean grace；By aramid fiber and silk
Fiber can increase the gas permeability and wearability of surface material by reasonable ratio simultaneously, and achieve the purpose that soft touch.
The corrosion oxidation phenomenon of bottom and surface layer joint face in order to prevent, is added the polytetrafluoroethyl-ne of reasonable parts by weight in primer
Alkene can effectively prevent the corrosion of bottom and surface layer joint face.The invention is strong, and distinct characteristics increase comprehensively
Gas and wearability, and bottom and surface layer is made to be not easy in hot humid environment to be divided by corrosion.

Performance test of the invention:
The gas permeability to embodiment 1 to 6, wearability, corrosion resistance, biocidal property are subjected to integration test below.
The antibacterial type swivel chair of embodiment 1 to 6 is subjected to wear rate test by GB/T3960-1983 method with synthetic leather.
The Household ornament wallpaper synthetic leather of embodiment 1 to 6 is subjected to gas permeability in 200Pa pressure using gas permeability detector
It can test.
The antibacterial type swivel chair of embodiment 1 to 6 is placed in 80 DEG C with synthetic leather, be covered in the environment of vapor 2 months into
The test of row corrosion resistance.
The swivel chair of embodiment 1 to 6 is attached on wooden basal plane respectively with synthetic leather, at room temperature, relative humidity 50-70%
Under conditions of, it stores 30 days, detecting it, (what the bacteriostasis rate data in following table took is in wooden base to the fungistatic effects of Escherichia coli
The average value of the testing result in face).
Following table shows the wearability, gas permeability, bacteriostasis property of each embodiment.
It will be seen that from upper table, wear rate of the invention, gas permeability, biocidal property are reinforced, when aramid fiber and silkworm
When silk fiber weight fraction ratio is 1, gas permeability achievees the effect that relatively good；Wearability increases with the dosage of aramid fiber,
Wear-resisting property is also reinforced therewith, but when aramid fiber reaches 25 parts, wearability has reached very high level, and wear-resisting
The floating of property is very small；On the basis of reaching 98% fungistatic effect, when cotton fiber and ramee weight fraction ratio are 2,
The tingling sensation of surface layer disappears, and keeps very high fungistatic effect；To sum up, the present invention tool have good wearability, gas permeability, suppression
Bacterium property has accomplished the purpose taken into account.When polytetrafluoroethylene (PTFE) parts by weight are 6 to 8, resistance to oxidation and corrosive nature are best simultaneously.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
