Problems solved by technology

On the other hand, the difference in thermal expansion coefficient between glass fiber and resin matrix is ​​large; the surface energy of glass fiber is high, which promotes hydrophilicity, so the wettability of resin to glass fiber is poor, the interface is not well bonded, and destructive stress is easily formed. Reinforced plastics are easy to delaminate, which affects the performance of the product, that is, the product cannot achieve ideal results in terms of strength, corrosion resistance and weather resistance

Abstract

The invention provides glassfiber reinforced plastic and a preparation method thereof, and relates to the technical field of plastic materials. The glassfiber reinforced plastic is prepared from the following raw materials: glassfiber, Nano-TiO2, acrylic resin, ABS resin, talc, polymethyl methacrylate, asbestos, an antioxidant, a coupling agent and a flexibilizer. According to the glassfiber reinforced plastic, the glassfiber and the asbestos are added to the base materials acrylic resin and the ABS resin for reinforcement, and by means of the scientific ratio of Nano-TiO2, the talc, polymethyl methacrylate, the antioxidant, the coupling agent and the flexibilizer, a finished material is endowed with good strength, corrosion resistance, weather fastness and mechanical properties as well ashigh impact strength and bending strength.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a glass fiber reinforced plastic and a preparation method thereof. Background technique [0002] Glass fiber reinforced plastic is a composite plastic based on glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. As a kind of composite material, due to its unique performance advantages, FRP has been widely used in aerospace, railway, decorative architecture, home furniture, building materials, bathroom and sanitation engineering and other related industries. Existing glass fiber reinforced plastics are made by the pultrusion process, specifically: under the traction of the traction device, the fiber reinforced material impregnated with resin is first preformed in the mold, and then heated to solidify and form it into FRP. Profiles, and finally cut into FRP products of required length. In the above preparation process, the glass fiber is direct...
