Abstract

The invention discloses a cooling liquid resistant PPS composite material. The PPS composite material comprises the following components in parts by weight: 30-90 parts of PPS resin, 10-70 parts of reinforced fibers, 0.05-3 part of a mercaptosilane coupling agent and 0.1-6 part of an additive containing a carbodiimide structure. According to the PPS composite material, the low-chlorine resin is adopted in a glass fiber reinforced PPS system, meanwhile, the mercaptosilane coupling agent is added into the system, and meanwhile, the additive containing the carbodiimide structure is matched so that the cooling liquid resistance of PPS can be obviously improved. Meanwhile, the invention also discloses a preparation method of the PPS composite material.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a coolant-resistant PPS composite material, a preparation method and application thereof. Background technique [0002] Polyphenylene sulfide (PPS) has excellent heat resistance, solvent resistance, high dimensional stability, excellent dielectric properties, excellent flame retardancy and mechanical properties, and is widely used in electronics, automobiles, machinery, and chemicals and other fields. About 40% of the modified PPS is used in the automobile industry, especially in the surrounding areas of the engine, such as automobile water pumps and automobile thermostats. Due to the particularity of the working environment, the parts used in this part are exposed to corrosive coolant liquid for a long time, which can easily lead to decomposition and cracking of the parts, causing abnormal operation of the engine. Contents of the invention [0003] Based on this,...
