Abstract
The invention discloses an anti-ultraviolet, low-warpage and flame-retardant reinforced polypropylene material and a preparation method thereof. The polypropylene material comprises the components: apolypropylene PP homopolymerized material, glass fibers, a flame-retardant masterbatch, a compatibilizer, a coupling agent, micapowder, an ultraviolet absorbent, an antioxidant and a lubricant; the polypropylene material is obtained by mixing all the components. By the way, according to the anti-ultraviolet, low-warpage and flame-retardant reinforced polypropylene material and the preparation method thereof, the production cost can be reduced through the synergistic effect of the micapowder and an illumination auxiliary agent, so that the polypropylene material has the advantages of high modulus, low warpage, excellent mechanical properties and good environmental protection performance.
Description
technical field [0001] The invention relates to the technical field of flame-retardant composite materials, in particular to an ultraviolet-resistant low-warpage flame-retardant reinforced polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin obtained by the polymerization of propylene. It is generally divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the arrangement of methyl groups. Polypropylene material has the advantages of non-toxic, odorless, and low density. Its strength, stiffness, hardness, and heat resistance are all superior to low-pressure polyethylene. It can be used at 100 ° C. It has good dielectric properties and high-frequency insulation. Unaffected by humidity. [0003] Patent CN201610151631 discloses a high CTI environmentally friendly flame retardant glass fiber reinforced PP material, which has flame retardancy and ...
