Problems solved by technology

However, PCT resin has poor cold resistance and is not suitable for weather-resistant use in various environments
[0003] Conventional PCT resin modified materials generally have poor rigidity, and usually add 10-20% glass fiber, which has poor rigidity and cannot be used as a structural or load-bearing material in a special environment.
[0004] When conventional PCT resin is used in contact with metal (especially copper), it will accelerate the decomposition of plastic due to the influence of metal ions, resulting in a decrease in material performance and poor weather stability

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-rigidity weather-resistant PCT / ASA alloy. Background technique [0002] PCT resin (1,4-cyclohexanedimethanol terephthalate) is one of the thermoplastic materials not widely used in China. It is a semi-crystalline material with very good chemical stability, mechanical strength and electrical insulation properties. And thermal stability, and the hygroscopicity is very weak, so it is widely used in various heat-resistant and chemical-resistant environments. However, PCT resin has poor cold resistance and is not suitable for weather-resistant use in various environments. [0003] Conventional PCT resin modified materials generally have poor rigidity, and usually add 10-20% glass fiber, which has poor rigidity and cannot be used as a structural or load-bearing material in a special environment. [0004] When conventional PCT resin is used in contact with metal (espe...
