Abstract

The invention discloses a chopped glass fiber enhanced polyformaldehyde material. The chopped glass fiber enhanced polyformaldehyde material is prepared from the following raw materials in part by weight: 50 to 80 parts of copolyoxymethylene resin, 10 to 30 parts of chopped glass fiber, 1 to 10 parts of aldehyde absorption agent, 0.1 to 5 parts of glass fiber leakage prevention agent, 0.1 to 5 parts of coupling agent, and 0.1 to 5 parts of antioxidant. The polyformaldehyde is used as a matrix resin, and the high-strength polyformaldehyde material is prepared by enhancement of the chopped glass fiber; the tensile strength of the polyformaldehyde material can reach 125 MPa, flexural strength can reach 180 MPa, notch impact strength can reach 7.5kj / m<2>, and the polyformaldehyde material is good in comprehensive performance, and the polyformaldehyde material can meet the application requirements of the polyformaldehyde in automobile industry, electronic and electrical industry, precision machinery industry and other industry.

Description

technical field [0001] The invention belongs to the field of new polymer materials, and in particular relates to a chopped glass fiber reinforced polyoxymethylene material and a preparation process thereof. The material is used to replace part of non-ferrous metals or alloys, and to expand its application in industries such as automobiles, electronic appliances, and precision machinery. application range. Background technique [0002] Polyoxymethylene (POM) is an unbranched linear highly crystalline polymer, because of its unique mechanical properties, excellent wear resistance and self-lubricating properties, oil resistance, chemical resistance, creep resistance And good thermal and electrical properties, low water absorption, can maintain its mechanical, chemical and electrical properties in a wide temperature range, and is widely used in automobiles, electronic appliances, household appliances, precision machinery and building materials and other industries.
