Description
Technical field
The present invention relates to heat insulating belt field, specifically, be a kind of exhaust insulation band.
Background technology
The gas extraction system of internal combustion engine is thermally shielded by existing a lot of ways now.But various modes have its respective pluses and minuses, and overall price/performance ratio is the lowest.Such as, (1) uses the exhaustor of cooling water sandwich.This method is to process a cooling jacket to exhaustor, and logical supercooled water circulating in intercalated water sleeve reduces the hull-skin temperature of exhaustor.This heat-insulating method reliability is high, good heat-insulation effect.But requiring very tight to the seal of inner sleeve, the forming technique of water collar is the highest, and if to a whole set of gas extraction system making water collar, cost of manufacture can be multiplied.During water collar work simultaneously, the mechanical power of meeting consumption of engine, reduces the efficiency of electromotor.It addition, use water collar to add water, the consumption of electricity equal energy source, maintenance and use cost also can be made to increase a lot.(2) asbestos layer is added to exhaustor.This method is a kind of mode in China market commonly used internal combustion engine especially Diesel Engine Exhaust Pipe.The heat-barrier material of China's high-power vehicular engine gas extraction system parcel uses asbestos cloth or asbestos ribbon mostly, and the effect of heat insulation of this heat-insulating method is poor.When exhaustor is warmed up to 600～700 DEG C, the constitution water of asbestos fibre separates out, and fibre structure is destroyed, asbestos layer entirety can become fragile, rub after can efflorescence.So insulating layer of asbestos effect when beginning to use is not bad, within the hull-skin temperature after heat insulation can being limited in 200 DEG C.But using in the near future, fiber is destroyed after high temperature, and hull-skin temperature is usually up to 300 DEG C the highest, constitutes a threat to the safety of internal-combustion engine system.Otherwise must frequently change, cause cost to increase.And, the strong carcinogenecity of human body is thoroughly disabled by developed country by asbestos material because of it.Suitable for application in productive life.(3) use heat shield that gas extraction system is thermally shielded.The method inorganic polymer material that lower-cost Kaolin is made makes a kind of gas extraction system heat shield, instead of the insulating layer of asbestos being originally coated on outside gas extraction system, and effect of heat insulation is fine.The heat-barrier material primary raw material that this heat-insulating method is used is common Kaolin, and preparation cost is relatively low, so the gas extraction system heat shield manufactured is lower than water-cooling exhaust pipe cost, and this structure is installed simple, the most harmless to health.But this piecemeal knockdown gas extraction system heat shield needs to make different contour structures according to every kind of different types of exhaust system structure, it is not suitable as the internal combustion engine exhaust system insulating product produced in enormous quantities.In production and infeasible.(4) ceramic thermal barrier layer spraying technology.This technology is the most universal, uses plasma spraying technology to spray zirconia ceramics thermal insulation layer in gas extraction system；Or application self-propagating technology prepares ceramic heat insulating coating.Result shows that the heat insulation of gas extraction system can be played well effect by this technology.But this technology is prohibitively expensive, and the ceramic coating sprayed expands in worst hot case lower linear and shrinks inconsistent with exhaustor, causes coating shedding to reduce effect of heat insulation.
Summary of the invention
It is an object of the invention to the heat insulation searching high and low cost of a kind of cost performance for internal combustion engine exhaust system, simple to operate, can unify in high volume make, to human body and environmentally friendly insulation system.Prior art is because of the problem of material Yu making, these advantages can not be coexisted, this set insulation system can effectively overcome these incompatible shortcomings, a kind of exhaust insulation band is provided, this heat insulating belt abandoned before drawback, according to requirements can wrap on the exhaustor of any size, be fixed by stainless steel lathe dog, band or stainless steel silk, reduce scattering and disappearing, every thermo-lag purpose of heat.And the material after technological invention processes, has high temperature resistant, smoke-free and tasteless, asepsis environment-protecting, the feature such as easy construction when using.
For achieving the above object, the present invention provides following technical scheme:
The present invention relates to a kind of exhaust insulation band, including ceramic fibre strip, it is characterized in that, ceramic fibre strip interior interpolation enhancing silk and the organic fiber that weight ratio is 15%～20%, described enhancing silk uses SUS304 stainless steel silk and alkali-free glass fibre silk, described organic fiber uses artificial viscose, described ceramic fibre strip burns 1.5～2.5 hours at 205～210 DEG C, combustion process is ventilated in stove, wind speed is 5～8m/s, in stove, oxygen content is 21%～25% so that the organic fiber content in described ceramic fibre strip drops to 2%～3%
As the further scheme of the present invention, described ceramic fibre strip uses the ceramic material of the classification temperature 1260 degree of standard.
As the further scheme of the present invention, the thickness of described heat insulating belt is 1～6mm, and width is 10～300mm.
Compared with prior art, the positive effect of the present invention is:
1. more effectively, on the basis of ensureing the heat insulation effect with heatproof, its cost is lower to gas extraction system heat insulation for the present invention, and operation is simpler even can individual be operated, it is easy to produces in enormous quantities, store and transports, harmless the most more environmentally friendly.
2. the present invention has carried out high temperature sintering process to ceramic fibre strip in advance, is burnt by organic fiber so that it is within content is reduced to 3% in the case of the physical and chemical performance keeping heat insulating belt varies less.So can ensure that ceramic fibre strip will not produce danger in use, and the characteristic such as its heatproof, heat insulation, fire prevention is barely affected.
3. compared to the exhaustor of cooling water sandwich, the cost of the present invention is lower, and the operation of I&M is the simplest, and thermal insulation can determine the consumption of heat insulating belt as requested.It addition, because existing high temperature resistant heat insulation material is all light heat-insulating material, the most do not manufacture too much burden to electromotor, its energy consumed is very limited；Compared to asbestos layer, the heatproof of the present invention is higher, and material uses temperature 1000 degree, maximum operation (service) temperature 1260 degree, and moment uses temperature 1650 degree.Can meet the temperature requirement of all internal combustion engine exhaust systems, material will not efflorescence.Most importantly to human body and environmentally friendly, the safest during use；Compared to ceramic thermal barrier layer spraying technology, the advantage of the present invention is that cost is the lowest, and is physically easier to perform.Most importantly the present invention will not produce because of the lifting of temperature when application and come off and reduce effect of heat insulation.Even if coming into question, the cost of replacing is the lowest.
