High-voltage-resistant-strength glass fiber reinforced polyester material and preparing method thereof

Abstract

The invention discloses a high-voltage-resistant-strength glass fiber reinforced polyester material. After glass fibers are pretreated at the ultralow temperature with a physical method, the bending resistance, the tensile performance and the wear resistance of the glass fibers are improved; original sizing materials on the surfaces of the glass fibers are oxidized and decomposed through high-temperature treatment, and water stored and adsorbed by the glass fibers is removed accordingly; then modification porosity carbon-nano-tube materials are grafted on the surfaces of the glass fibers with a chemical method, and a hole structure is formed; when the glass fibers and a matrix are compounded, some chain segments of high polymers enter holes to achieve the anchoring-similar effect. In this way, binding force between interfaces of the glass fibers and the polymers is increased, and the impact resistance of a product is improved; meanwhile, nylon 6 is creatively compounded into unsaturated polyester, the special performance of the nylon 6 and the special performance of the unsaturated polyester are achieved, and the prepared glass fiber reinforced polyester material has the advantages of being low in shrinkage rate and high in voltage-resistant strength, mechanical performance and anti-corrosion capability.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a polyester glass fiber reinforced plastic material with withstand voltage strength 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. Nowad...

However, in this paper, the resin matrix and glass fiber are directly compounded, and the compatibility between the two is poor. It is necessary to modify the existing glass fiber and then add it to the matrix resin.
