Abstract
This invention discloses a low-temperature-resistant PC/PBT plastic alloy for hulls of mowing machines, front bumpers and panels of automobiles and industrial pulleys. The PC/PBT plastic alloy comprises: PC 60-85 wt.%, PBT 4-30 wt.%, toughening modifier 3-25 wt.%, compatibilizer 1-3 wt.%, antioxidant 0.2-0.6 wt.% and processing auxiliary 0.2-1.0 wt.%. The PC/PBT plastic alloy has such advantages as high impact strength, high low-temperature impact strength, high modulus, high rigidity, high surface luster and low density, and can be normally used at -40 deg.C.
Description
Technical field
The present invention relates to polymeric material field, particularly a kind of low temperature resistant PC/PBT polyblend mainly is suitable for making the mower shell that needs low temperature resistant occasion, the industrial pulley that automobile front beam, panel board and needs are low temperature resistant etc.
Background technology
PBT (polybutylene terephthalate Polybutylene Terephthalates) is one of the most tough and tensile engineering thermoplastic materials, and it is a those semi-crystalline materials, and extraordinary chemical stability, physical strength, electrical insulation characteristics and thermostability are arranged.Be widely used in: home appliances, electric elements, automotive industry.
PC (polycarbonate Polycarbonate) is a kind of noncrystal engineering materials, has good especially resistance to impact shock, thermostability, glossiness, inhibition bacterium characteristic, flame-retarding characteristic and resistance to crocking.
PC/PBT is the mixture of polycarbonate and polybutylene terephthalate, has the two overall characteristic of PC and PBT, for example the chemical stability of the high tenacity of PC and dimensional stability and PBT, thermostability and lubricating property etc.PC/PBT is fit to make the product that vehicle body plate, automobile side backplate, splash pan, automobile door frame etc., wheel casing, bumper and requirement have anti-chemical reaction and erosion resistance, thermostability, shock resistance and geometrical stability.
But the same with other plastics, its toughness of PC/PBT polyblend can be subjected to the very big influence of temperature, generally shows as low temperature brittleness.Therefore plastics are carried out modification, improve its resistance to low temperature, to widen the plastic applications field.
Summary of the invention
