Problems solved by technology

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.

Embodiment Construction

[0012] An impact-resistant polyester fiberglass material, made of the following raw materials in parts by weight: unsaturated polyester 104, nylon 1215, glass fiber 18, carbon nanotube 0.4, graphene oxide 1.5, polysorbate 4, stainless steel powder 2, Calcium formate 1.2, silane coupling agent DL6028.9, fumed silica 3, rosemary essence 0.03, methyl ethyl ketone peroxide 2.6, 1% ethanol aqueous solution in proper amount.

[0013] The manufacturing method of described a kind of impact-resistant polyester FRP material, comprises the following steps:

[0014] (1) Place the glass fiber in the ultra-low temperature treatment equipment at minus 100°C to minus 200°C for ultra-low temperature treatment for 10-15 hours, take it out and naturally return to temperature, put it in a muffle furnace at a temperature of 520-580°C, heat treatment for 1-2 Hours, natural warming made pretreated glass fiber;

[0015] (2) Stir and mix the silane coupling agent DL602 and polysorbate, then ultrasoni...

Abstract

The invention discloses an impact-resistant 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 inter-layer shear performance 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 12 is creatively compounded into unsaturated polyester, and the prepared glass fiber reinforced polyester material has the advantages of being resistant to impact, high in intensity, excellent in fire resistance and resistant to corrosion.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to an impact-resistant 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 mater...
