Problems solved by technology

At present, most of the new energy vehicle battery casings on the market are still lead-acid batteries. After the casing is sealed with glue or heat, there will be residual stress. These stresses can easily lead to cracking of the material. Therefore, flame-retardant ASA materials are required to ensure environmental protection. In the case of burning, it also needs to have good impact toughness, solvent resistance and stress cracking resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a special flame-retardant ASA material for a new energy vehicle battery casing and a preparation method thereof. Background technique [0002] With the continuous development of my country's economic construction and continuous improvement of people's living standards, automobiles have entered the family, and the demand for oil is also increasing. The fuel of automobiles in our country mainly comes from oil, and the demand for oil is increasing. Because oil reserves are limited, oil is facing the danger of depletion, and it also seriously pollutes the environment. For this reason, the country advocates the development of various new energy vehicles. [0003] ASA resin is a terpolymer of acrylonitrile, styrene, and acrylate, and is a substitute for ABS resin. Compared with ABS, due to the introduction of acrylate rubber without double bonds instead of butadiene rubber, ...
