Problems solved by technology

[0002] PC resin is polycarbonate. Polycarbonate has the advantages of good mechanical properties, high unnotched impact strength, stable size and good creep resistance. ABS resin is a polymer of acrylonitrile, butadiene and styrene. ABS resin It has the advantages of good formability, good impact resistance and good fluidity, so that the composite material formed by the complementary combination of PC and ABS has the advantages of both, and the solubility of PC resin and ABS resin is close, indicating that PC resin and ABS resin have Certain compatibility, but there are still problems such as unstable performance in the actual application process, which makes the joint strength of PC / ABS composite products low, the demoulding effect is not good, and the surface of blow molding products is still rough, Defects such as blistering and cracking, and the flame retardant effect of PC / ABS composites is poor
