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.
