Problems solved by technology

[0007] In the prior art, basalt fiber and thermosetting resin are used to composite. Although this composite material has high strength and high impact resistance, the disadvantage is that the thermosetting resin cannot be processed again after being used once. This kind of product cannot be realized after being discarded. High-value recycling causes a lot of waste and pollutes the environment

Abstract

The invention belongs to the technical field of high polymer material, and discloses a bidirectional continuous basalt fiber reinforced thermoplastic resin composite sheet material and a preparation method thereof. The composite sheet material is prepared from the following components by weight: 40-60 parts of a thermoplastic resin, 40-60 parts of a continuous basalt fiber and 0.2-0.5 part of a titanate coupling agent. The invention also discloses a preparation method of the bidirectional continuous basalt fiber reinforced thermoplastic resin composite sheet material. The bidirectional continuous basalt fiber reinforced thermoplastic resin composite sheet material provided by the invention has good flame resistance, high temperature resistance, comprehensive performance and a low price.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a bidirectional continuous basalt fiber reinforced thermoplastic resin composite plate and a preparation method thereof. Background technique [0002] Continuous fiber reinforced thermoplastic resin is composed of fiber and resin. Most thermoplastic resins have low tensile strength, but have high toughness and plasticity; fibers have high tensile strength, but are easily damaged and Not easy to form and process. The combination of fiber and resin complements the defects of the two, so that the comprehensive performance of continuous fiber reinforced thermoplastic resin composites is greatly improved. Compared with traditional steel and aluminum, its density is about 1 / 5 of steel and about 1 / 2 of aluminum; its specific strength and specific modulus are much higher than those of steel and aluminum alloys, so in terms of stiffness and strength Under the same conditions, it...
