Abstract

The invention discloses a hydrolysis-resistance alcoholysis-resistance glass fiber reinforced PPA (phenyl-propanolamine) material and a preparation method thereof. The hydrolysis-resistance alcoholysis-resistance glass fiber reinforced PPA material consists of the following components in percentage by weight: 46 to 76 percent of polyphthalamide resin, 20 to 50 percent of glass fibers, 0.3 to 0.6 percent of heat stabilizer, 0.2 to 0.4 percent of alcoholysis-resistance protective agent, 0.1 to 0.3 percent of hydrolysis-resistance protective agent, 0.4 to 0.8 percent of polarity OP (oxidized polyethlene) wax, 0.1 to 0.3 percent of nucleating agent and 1.0 to 2.0 percent of black color masterbatch. The reinforced PPA material disclosed by the invention not only has excellent mechanical property, but also has excellent hydrolysis-resistance and alcoholysis-resistance characteristics. When the hydrolysis-resistance alcoholysis-resistance glass fiber reinforced PPA material is soaked in hot water and ethylene glycol solution for a long time, over 80 percent of mechanical property can be kept. The hydrolysis-resistance alcoholysis-resistance glass fiber reinforced PPA material can be widely used in the automobile industry and other fileds. When the hydrolysis-resistance alcoholysis-resistance glass fiber reinforced PPA material is used for manufacturing parts which are in contact withwater and antifreezing solution for a long time, not only can the manufacturing cost of the parts be reduced, but also the weights of the parts can be greatly reduced.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a hydrolysis-resistant and alcoholysis-resistant glass fiber reinforced PPA material and a preparation method thereof. [Background technique] [0002] PPA (polyphthalamide) resin is a semi-aromatic polyamide made of phthalic acid. Under high temperature and high humidity, the tensile strength of PPA is 20% higher than that of nylon 6 and higher than that of nylon 66; The flexural modulus of PPA material is 20% higher than that of nylon, the hardness is greater, and it can resist long-term tensile creep; and the resistance of PPA to gasoline, grease and coolant is also stronger than that of PA. [0003] With the rapid development of the automobile industry, replacing steel with plastic has become the trend and direction of the development of automobile materials. Glass fiber reinforced PPA materials are widely used in water chamber parts of automobiles, such as thermos...
