Abstract

The invention discloses a manufacturing process for an anti-impact low-shrinkage PC bag. The anti-impact low-shrinkage PC bag is prepared from the following raw materials: 10%-15% of a PC raw material, 50%-75% of an ABS raw material, 10%-25% of modified talcum powder, 1%-3% of tris(tribromophenyl) cyanurate and 2%-8% of GF. According to the manufacturing process for the anti-impact low-shrinkage PC bag in the invention, the excellent properties of both PC and ABS are fully combined, the heat resistance and tensile strength of ABS are improved, and the viscosity of a PC melt is reduced; the modified talcum powder is added to improve processing properties and reduce the sensitivity of the internal stress and impact strength of the produced bag to the thickness of the produced bag; and compared with the prior art, the weight of the produced bag is reduced by at least 20%, fire-retardant and flame-retardant performance are improved, strength can be ensured at the same time, and the bag hasgood resistance to high temperature and cold, and shows good hardness in the case of low density, so the normal use of the bag is ensured.

Description

technical field [0001] The invention relates to the technical field of cases and bags, in particular to a process for making impact-resistant and low-shrinkage PC cases and bags. Background technique [0002] In today's society, suitcases have become one of the essential supplies for people to travel long distances. Whether it is for business people who are busy all year round, people who like to travel, or students who study abroad, they are equipped with pull rods and rollers. Advanced trolley cases have become an essential tool for people to travel and travel. With the improvement of people's living standards, the requirements for trolley cases are getting higher and higher. [0003] However, the existing luggage production technology is backward, not easy to process, and the materials used are relatively single, which cannot guarantee waterproof and anti-collision performance at the same time, and the use stability is poor, and the mechanical properties and thermal stabi...
