Abstract

The invention discloses an anti-shearing flame-retardant glass fiber composite material. The material is characterized by being prepared from the following components in parts by weight: 70 to 90 parts of hyperbranched borate, 4 to 8 parts of epoxy fluorophenyl sulfuryl calixpyrrole, 20 to 30 parts of glass fiber, 1 to 3 parts of 2, 2'-dihydroxy-4, 4'-dimethoxybenzophenone-5, 5'-disulfonic acid, 1to 2 parts of coupling agent and 0.2 to 0.5 part of phosphorus pentoxide. The invention also discloses a preparation method of the anti-shearing flame-retardant glass fiber composite material. The anti-shearing flame-retardant glass fiber composite material disclosed by the invention is better in comprehensive performance, better in performance stability, higher in shearing force strength, more excellent in heat resistance and flame retardance and easier to process and form.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a shear-resistant flame-retardant glass fiber composite material and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the advancement of science and technology, various high value-added materials have emerged one after another, bringing more excitement to people's lives. Composite material is one of the more common ones, which is composed of two or more materials with different properties, through physical or chemical methods, to form materials with new properties on the macro (micro) level. Since various materials learn from each other in terms of performance and produce synergistic effects, the comprehensive performance of composite materials is better than that of the original constituent materials to meet various requirements. [0003] Glass fiber composite material is a new type of composite mat...
