The coating can be cured at the temperature of 140 DEG C for 30min; compared with the traditional PVC (Polyvinyl Chloride) vehicle bottom coating, the low-density environment-friendly damping and denoising protective coating has the advantages that a cured substance has the advantages of favorable elasticity, good corrosion resistance, low density, strong adhesive force, excellent damping and denoising performances, no halogen, environment friendliness and the like; the coating can be applied to positions such as a floor, a wheel cover, a side body and the like of a car to play roles in damping, denoising, resisting to stone impact and the like.
Description
Technical field
The present invention relates to a kind of automobile chassis paint, particularly a kind of low density environmental protection damping noise reduction protective cover.
Background technology
Automobile in the process of moving; at the bottom of car and mudguard for vehicle wheel etc. locate often will be subject to the impact of silt, rubble and sewage etc. and wash away; thereby cause car sole easily by corrosion, to be lost protective capability; in addition; in running car, the vibrations of engine, wheel can cause empathizing with chassis in a certain frequency; make people produce uncomfortable sensation, therefore need to be at these position brushing chassis damping noise reduction protective covers.The automobile using is in the market mostly PVC type with chassis paint, the winter hardiness of product, elasticity, ageing resistance are poor, density is larger simultaneously, be unfavorable for reducing car body deadweight, reduce fuel oil consumption, the economy that improves automobile, contains the harmful materials such as halogen in addition, is unfavorable for environmental protection.
Summary of the invention
In order to solve the deficiency of above-mentioned currently available products, the invention provides a kind of low density environmental protection damping noise reduction protective cover.This coating is in triturating, first consider to there is the feature of environmental protection, it is matrix resin that coating adopts pulverous thermoplastic acrylic resin, coordinate softening agent to use, at 140 ℃, there is good plasticizing function, do not contain halogen, in baking and incineration course, there will not be dehydrochlorination reaction, friendly to environment.It is less important has lower density, adopts Powdered EVA resin to coordinate whipping agent, blowing promotor, linking agent, additional crosslinker to form foaming system, utilizes numerous abscess in matrix to play the effect that reduces coating density.The in the situation that of spraying same thickness, reduce the usage quantity of coating, indirectly reduce vehicle weight, reduce fuel oil consumption, to reach the object of economy.Finally to reach effect of vibration and noise reduction good, because thermoplastic acrylic resin, EVA resin all have good elasticity, the vibrations, the noise that in the time of can be to automobilism, produce play shock absorption, coating has numerous abscesses simultaneously, and abscess is open cell type, can effectively absorb sound wave, play the effect of damping, sound absorption, noise reduction.
