Problems solved by technology

[0003] Commonly used polycarbonate (PC) materials with solvent resistance are mainly to introduce PBT, PET, ABS and other crystalline material components into PC through blending modification to produce alloy composite materials to improve the solvent resistance of materials. However, PBT, PET and ABS materials are easy to burn due to their high oxygen index, low heat resistance, and low impact strength, resulting in a decrease in the flame retardancy, heat resistance, and impact strength of the alloy material, and the addition of PBT and PET materials will cause the surface gloss of the material The degree is affected, so the application in the appearance parts products in the field of electronics and electrical engineering is limited to a certain extent

Abstract

The invention discloses a high-gloss and long-lasting solvent-resistant polycarbonate material. The raw materials include the following components in mass percentages: polycarbonate 81-94%, polyurethane 2-10%, flame retardant 2-8%, Antioxidant 0.1-0.5%, lubricant 0.2-0.5%; the invention adopts polyester polyurethane (TPU) to not only improve the impact strength of polycarbonate (PC) material, but also improve the long-term solvent resistance of the material, And the addition of an appropriate proportion has no obvious effect on the heat resistance of polycarbonate (PC) materials, which can meet the heat resistance requirements of electrical products.

Description

technical field [0001] The invention relates to the technical field of modified polymer materials, in particular to a high-gloss and long-lasting solvent-resistant polycarbonate material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is widely used in electronic devices, aerospace, automobiles, construction, medical equipment and other fields due to its excellent comprehensive performance; Products have become the first choice for consumers to choose electrical and electronic products. Due to the better appearance, quality and grade of spray-painted products, its technology has been widely used in the fields of spraying electronics, electrical engineering, home appliances, automobiles and so on. The surface has a metal appearance and a modern spray paint switch. The secondary spraying process is adopted. The primer gives the product a metallic luster, conceals surface defects of the product, and isolates the air and solvent from contactin...
