Conductive fiberglass reinforced plastic material and manufacturing method thereof

Abstract

The invention discloses a conductive fiberglass reinforced plastic material. After ultralow temperature pretreatment is performed on fiberglass through a physical method, the bending resistance and the tensile property of the fiberglass are improved; through high temperature treatment, an original sizing material on the surface of the fiberglass is oxidized to be decomposed, and then water stored and adsorbed in the fiberglass is removed; the surface of the fiberglass is grafted with a modified porous carbon nano tube material through a chemical method; a hole structure is achieved, when the fiberglass is composited with a matrix, chain segments of some high polymers enter holes, a similar anchoring effect is achieved, the binding force betrween the fiberglass and a polymer interface is enhanced, the impact resistance of the product is improved, and the prepared fiberglass reinforced plastic material has the advantages of being good in mechanical property, corrosion resistance and electromagnetic shielding effect.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a conductive polyester glass fiber reinforced plastic material and a manufacturing method thereof. Background technique [0002] Toys are children's angels. Toys attract children's curiosity and attention with their bright colors, graceful and strange shapes, dexterous activities, and pleasant sounds. There are various types of toys and play methods, including plush toys, plastic toys, paper toys, electronic toys, wooden toys, metal toys, leather toys, educational toys, early education toys, fiberglass toys, children's cars and other miscellaneous items Toys, among which plush toys and children's cars are the best sellers. Metal materials and plastics are often used as materials for children's cars. Metal materials are not only expensive, heavy, but also prone to rust, while plastics are brittle, easy to break, and easy to age. Nowadays, FRP materials ar...
