Abstract

The invention discloses a long glass fiber-nylon resin composition and a preparation method thereof. The long glass fiber-nylon resin composition comprises, by weight, 100 parts of nylon resin, 20 to 30 parts of long glass fibers, 3 to 10 parts of a flexibilizer, 0.5 to 2 parts of a flowable agent, 1 to 2 parts of an anti-oxidant and 2 to 4.5 parts of a heat stabilizer. The preparation method has a simple principle, a low cost, and low equipment requirements. The long glass fiber-nylon resin composition has the advantages of good rigidity, good impact resistance, alkali and acid resistance, aging resistance, oxidation resistance, and weatherability.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a long glass fiber nylon resin composition and a preparation method thereof. Background technique [0002] Nylon resin, that is, polyamide, has excellent mechanical strength, wear resistance, self-lubricating property, corrosion resistance and good processing and molding properties. Base resin with excellent comprehensive properties. However, the traditionally prepared nylon resin composition has poor heat resistance, is prone to aging, oxidation, and corrosion by acid and alkali, which limits its further application. Contents of the invention [0003] The main purpose of the present invention is to provide a long glass fiber nylon resin composition with acid and alkali resistance, good rigidity, anti-aging and anti-oxidation and a preparation method thereof. [0004] The present invention proposes a long glass fiber nylon resin composition, which comprises the following comp...
