Glass fiber toughened and reinforced nylon 6 composite material, preparation method and application thereof

Abstract

The invention discloses a glass fiber toughened and reinforced nylon 6 composite material, a preparation method and application thereof, wherein the glass fiber toughened and reinforced nylon 6 composite material comprises, in parts by weight, 50 parts to 75 parts of a PA6 resin, 20 parts to 40 parts of an alkali-free glass fiber, 1 part to 8 parts of a graft elastomer, 1 part to 3 parts of a grafted polyolefin, 0.1 to 1.2 parts of a glass fiber dispersant and 0.1 parts to 0.6 parts of an anti-oxidant. This composite material is prepared by a twin-screw extruder and also used for automobile cooling fans. The invention has the following advantages that this composite material has excellent mechanical properties, and excellent high, low temperature resistance performance. Besides, this invention ensures the uniform distribution of the material composition, particularly for glass fiber which is uniformly distributed in a matrix resin(PA6), which solves the problems of uneven distribution and exposure of the glass fiber. Therefore the fans made from this material have excellent dynamic balance performance, brightening surfaces and no glass fiber flow line and exposure.

Description

Technical field [0001] The invention belongs to the field of material chemistry, and specifically refers to a glass fiber reinforced and toughened nylon 6 composite material and a preparation method and application thereof. Background technique [0002] In the past ten years, my country’s automobile industry has developed vigorously. In 2009, its total production and sales exceeded 18 million, ranking first in the world. It has become a global automobile production and sales country. With the shortage of oil resources and rising oil prices, automobile lightweight has become a major issue for the development of the automobile industry. The application of engineering plastics is an inevitable choice for automobile lightweight. The degree of plasticization of automobiles shows the manufacturing level of the industry. All foreign automobile interior and exterior trim parts use plastic parts. Plastics for automobiles exceed 160 kg per vehicle. In recent years, the development and ap...
