Problems solved by technology

PBT modification mainly starts from two aspects. One is to adopt chemical modification methods, that is, to make it have better performance and new functions through chemical methods such as copolymerization, grafting, block, cross-linking or degradation; The physical modification method is used to improve and improve the overall performance of PBT by filling and reinforcing with inorganic materials, blending with other resins, and adding various additives. There are many imperfections

Description

technical field [0001] The invention relates to a polymer material, in particular to a PBT composite material which is antistatic, toughened, reinforced and stiffened. Background technique [0002] Polybutylene terephthalate (PBT) has been widely used in electronic appliances, home appliances, automobile industry, mechanical equipment and other industries due to its excellent heat resistance, fatigue resistance, weather resistance, low friction coefficient and other properties. However, the use of PBT alone has disadvantages such as low heat distortion temperature, easy combustion, shrinkage and warping of parts, poor mechanical properties, especially notched impact strength of products, etc. Therefore, PBT is rarely used alone, and most of them need to be modified before they can be applied. PBT modification mainly starts from two aspects. One is to adopt chemical modification methods, that is, to make it have better performance and new functions through chemical methods s...
