Description
Technical field
The present invention relates to a kind of automobile wheelhouse and manufacture method thereof, be specifically related to a kind of PP/PET and environment-friendly waterproof anti-petrol car wheelhouse and manufacture method thereof are blended.
Background technology
Carpet, is with natural fiber or chemical synthetic fiber class raw materials such as cotton, fiber crops, hair, silk, grass, manually or mechanical technology carries out knitting, synthetic tuft or the ground paving application that is formed by weaving.It is to have one of traditional industrial art category of long history in world wide.It is covered in the ground of house, hotel, gymnasium, show room, vehicle, boats and ships, aircraft etc., is reduced noise, heat insulation and decorative effect.Carpet sorting technique is a lot, divides by manufacturing process and has manual knotted carpet, hand woven plain weave carpet, manual tufted carpet, manual felt carpet, machine-made carpet；Divide by purposes and have carpet, a heatable brick bed blanket, wall tapestry, prayer rug etc.；Divide by raw material and have wool carpet, silk rug, jute rug, chemical fibre carpet etc..
Along with economic fast development, improving constantly of people's living standard, automobile industry development is rapid, and people are to the grace that the requirement of automobile is not only the quality of automobile itself, function and outward appearance, and the requirement to the upholstery of automobile is more and more higher.The wheelhouse of automobile generally used plastics wheelhouse in the past, and present, and along with the utilization of car carpeting is more and more extensive, present car carpeting is used not only for the place such as automobile cab, luggage case, and the wheelhouse of automobile generally also uses carpet.
Automobile outer wheel casing rug can produce absorption noise, the performance of antivibration vibration damping, thus reaches the effect of automobile absorbing sound and lowering noise in the process of moving, and the impact of surrounding and passenger is reduced by the noise produced by motor racing.
Existing automobile wheelhouse typically has two kinds: the first is PE or PP through injection, plastics sucking moulding, and shortcoming is Heavy Weight, relatively costly, smooth surface, automobile use during sandstone to beat noise big, and fragile under low temperatureization；The second be needling process prepare hot melt felt, its main component is PP/PET fiber, heated, mold after make wheelhouse product, advantage is low cost, light weight, and sound-absorption vibration-reduction effect is good, but because it is loose structure, Water-proof and oil-proof poor effect during use.
In order to meet the people's continuous pursuit to quality of the life, also for economic development, therefore, it is necessary to develop one not only there is sound-absorption vibration-reduction function, also there is the waterproof anti-automobile wheelhouse having function.
