Abstract

The invention belongs to the technical field of high molecular materials, and discloses a high-heat-resistant transparent reinforcing material with strong universality, good heat resistance and high transparency as well as a preparation method and an application thereof. The reinforcing material contains the following components by mass percent: 59% to 93% of mixture of polymethyl methacrylate and styrene-maleic anhydride copolymers, 5% to 30% of glass fibers, 1% to 30% of flexibilizer, 0.1% to 1% of antioxidant and 0.5% to 5% of processing aid. The refractive index of an obtained resin composition is matched with glass fiber phases by applying and regulating the adding proportion of two different resins, so that the reinforcing material is transparent, wherein the transparency of the reinforcing material can reach 87%; and the high heat deformation temperature of the obtained reinforcing material is realized, so that the reinforcing material has the advantages of good heat resistance, high transparency, high strength, good dimensional stability, good comprehensive performance and the like. Thus, the reinforcing material can be applied to various electrical appliances and decorative products, and is particularly suitable for front frames of televisions, air conditioner panels, outer frames of sound equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a highly heat-resistant transparent reinforcing material with strong versatility, good heat resistance and high transparency, and a preparation method and application thereof. Background technique [0002] Glass fiber reinforced thermoplastics (referred to as glass fiber reinforced plastics, GRTP) first appeared in the 1950s. After years of development, CRTP has accounted for more than 1 / 4 of the total composite materials in the world today, and has grown steadily. GRTP is a light-weight and high-strength composite material, and the content of glass fiber is generally 10-50wt%. The base plastics used are polyamide, polypropylene, polyethylene, AS, ABS, PET, PBT, polycarbonate, polyoxymethylene, polyphenylene ether, polyphenylene sulfide, polysulfone, polyethersulfone, polyamide-imide , polyetherimide, polyether ether ketone, chlorinated polyether, polyvinyl...
