Abstract
The invention discloses a kind of refrigeration equipment environmental protection and energy saving structure sheaf and its applications.The structure sheaf is made of HFO blown rigid polyurethane froth bed with modified aromatic race vinylite end cap, modified aromatic race vinylite is vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer and acrylonitrile-butadiene-styrene (ABS) polymer melt blended material, in modified aromatic race vinylite, vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer weight content is 20~95%.Refrigeration equipment environmental protection and energy saving structure sheaf prepared by the present invention overcomes HFO foaming agent and ABS end lid in refrigeration equipment now and improves refrigeration equipment environmental protection and energy saving performance with the use of the problem of will appear material cracks.Simultaneously because it still contains ABS material, good mouldability and glossiness are remained, so that the structure design of refrigeration equipment is able to achieve diversification and taste high-endization.
Description
Technical field
The invention belongs to refrigeration equipment manufacturing technology fields, in particular it relates to a kind of refrigeration equipment environmental protection and energy saving
Structure sheaf.
Background technique
Refrigeration equipment generally uses hard polyurethane foams as thermal insulation layer, and hard polyurethane foams generally use at present
Pentamethylene (CP), hydrofluoroalkane (HCFC, HFC) and HF hydrocarbon (HFO) are used as foaming agent.Due to forth generation foaming agent hydrogen fluorine alkene
Hydrocarbon HFO has the latent value (GWP) of lower greenhouse effects and a zero latent value (ODP) of consumption ozone, at the same using HFO foaming agent every
Thermosphere can improve refrigerating device heat insulation performance, refrigeration equipment energy consumption grade be effectively reduced, therefore energy-saving and environment-friendly HFO will gradually can
The foaming agents such as the hydrogen fluorochlorohydrocarbon before substitution (CP, HCFC, HFC).
But HFO as foaming agent when, HFO has severe corrosive, especially HFO pairs to plastic part in refrigeration equipment
Common acrylonitrile-butadiene-styrene (ABS) (ABS) end cap generates serious environmental stress, wherein HFO corrosivity ratio CP, HCFC
It is even more serious with HFC.Generally believe that HFO foaming agent is difficult to apply the refrigeration equipment in ABS end lid in industry at present, reason exists
In HFO foaming agent belongs to fluorochemical, is easy to corrode resin, and boiling point is lower, gasification is easy under room temperature, activity performance is more
Greatly.When HFO foaming agent enters in ABS resin, since HFO foaming agent has stronger solvation, macromolecule foams in HFO
It can be plasticized under the influence of agent.Wherein butadiene rubber is easier to absorb foaming agent, butadiene rubber and acrylonitrile-benzene in ABS
Ethylene interfacial interaction dies down, in stress concentration region, especially refrigeration equipment ABS product corner part and low temperature contact zone
Domain is easier to wreck, and often appears as multiple crazing and cracking.In addition, ABS end lid have preferable processability and compared with
High glossiness, this makes the structure of refrigeration equipment design more diversified and taste more high-endization.Therefore, it is necessary to find solution
Certainly ABS door body end cap and the compatible application method of HFO foam insulation.
Patent CN 103319834 is disclosed using HIPS, PE and SBS blending and modifying HIPS material as refrigeration equipment mouth frame,
Although having preferable chemical corrosion resistance, modification HIPS material preparation process is complex, and its gloss is poor, it is difficult to
Meet high-end taste required by refrigeration equipment product appearance.
Summary of the invention
The present invention is directed to overcome the defect of the above-mentioned prior art, a kind of end cap made of modified ABS resin, institute are provided
It states end cap and overcomes ABS end lid and be difficult to compatible problem with HFO foam insulation, the effective foaming agent of resistance to HFO corrosion, in high/low temperature
It under circulation change, will not crack, while remain ABS end lid good moldability and the higher advantage of glossiness.
Another object of the present invention is to provide a kind of refrigeration of end cap made of ABS resin comprising the modification to set
Standby environmental protection and energy saving structure sheaf.
Another object of the present invention is to provide the refrigeration equipment environmental protection and energy saving structure sheafs to prepare refrigerator, refrigerator-freezer and wine
Application in cabinet.
Foregoing invention purpose of the invention is achieved by following scheme.
Vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is preparing the application in refrigeration equipment end cap, described
Vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is blended with ABS to be prepared into modified aromatic race vinylite and makes again
For at refrigeration equipment end cap；In modified aromatic race vinylite, relative to vinyl cyanide-aromatic vinyl-unsaturation
The total amount of olefine acid ester polymer and ABS, vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer weight content are 20
~95%.
Inventors have found that part ABS resin is substituted using vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer,
High-low temperature resistant, the anti-aging and resistance to chemical corrosion of material can greatly be promoted.When modified aromatic race vinylite
In, when vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer weight content is 20~95%, end cap will not be generated open
Split phenomenon.
Preferably, the weight content of the vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is 30~95%.
Inventors have found that when vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer dosage within this range when, can be into one
Step keeps end cap flat and smooth.
When vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer too high levels, modified aromatic race ethylene can be given
The processability of base resin is brought a negative impact, and makes it difficult to be molded into end cap by processing.Consider moulding processability, this hair
The content of bright vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer can be more preferably 30~60%.Vinyl cyanide-
When aromatic vinyl-ethylenic unsaturation acid ester polymer too high levels, cost can also be significantly risen.Comprehensive performance and cost it is excellent
The dosage of gesture, vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer of the present invention is more preferably 30 ~ 40%.
Preferably, in modified aromatic race vinylite, the weight content of ABS is at least 5%.
In modified aromatic race vinylite, can also contain suitable auxiliary agent, the auxiliary agent can be lubricant,
The auxiliary agent commonly used in the art such as antioxidant.
In the vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer, the vinyl cyanide is acrylonitrile or first
