Description
Technical field
The present invention relates to a kind of bumper and preparation method thereof, particularly relate to a kind of Environment-friendlybamboo-plastic bamboo-plastic automotive bumper and preparation method thereof.
Background technology
Bumper is the security device absorbing the foreign impacts power that relaxes, protection vehicle body front and rear part.
Before 20 years, car front/rear collision bumper is based on metallic substance, is pressed into U-lag steel with the steel plate stamping that thickness is more than 3 millimeters, surface treatment chromium plating, rivet with longitudinal beam or weld together, having one section of larger gap with vehicle body, seems the parts added up.
Plastic bumper has intensity, rigidity and ornamental, from safety, can play shock absorption when automobile crashes, car body before and after protection; From the appearance, very naturally one piece can be combined in car body, completely integral, have well ornamental, become the vitals decorating car external form.
Along with the development of automotive industry, bumper has also moved towards on the road of innovation as a kind of important security device.The car front/rear collision bumper of today, except keeping original defencive function, also will be pursued and the harmony of car body moulding and unification, the lightweight of pursuit itself.In order to reach this object, the front/rear collision bumper of current car have employed plastics, and people are called plastic bumper.
The plastics that plastic bumper uses, use Polyester and polypropylene-based bi-material substantially, adopt injection moulding to make.The such as collision bumper of beautiful 405 cars, have employed polyester-based material and makes by reaction injection mold forming method.And the collision bumper of the model cars such as the Audi 100 of masses, golf, the Santana in Shanghai, the Xiali of Tianjin, have employed the polypropylene-based material by injection method of forming and make.
Wood plastic composite (wood-plastics composites, be called for short WPC) be the modified thermoplastic material of filling with xylon or vegetable fibre, strengthening, have the cost of timber and plastics and the advantage of performance concurrently, through to extrude or compression moulding is section bar, sheet material or other goods, substitute timber and plastics.
Bamboo fibers is a kind of cellulosic fibre extracted from the bamboo of self-sow, is the fifth-largest natural fiber after cotton, fiber crops, hair, silk.Bamboo fibers have good ventilation property, moment the characteristic such as water-absorbent, stronger wear resistance and good dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function.
Bamboo powder filled matrix material section is adopted to reduce costs, but because bamboo fibers is hydroaropic substance, surface has a large amount of polar functional groups, with the recombination process of plastics, and it is poor to there is higher interfacial energy between hydrophobic substance polypropylene, the material that two kinds of polarity is different is difficult to reach surface fully and mutually merges.Therefore how to adopt properties-correcting agent that bi-material is fully merged, guarantee its mechanical property, become a difficult point of research bamboo fibers polypropylene composite material research.
