Problems solved by technology
[0004] However, the sheet material of IMR film is usually PET film. Due to the defects of PET film and ink that are not resistant to high temperature, IMR film is now mostly used in thicker product casings, and it is rarely used in high-end ultra-thin products.

Abstract
The invention relates to the technical field of polymer materials, in particular to a carbon fiber reinforced polycarbonate composite material used in IMR molding and its products. The composite material includes by weight parts: 100 parts of polycarbonate resin; 10-60 parts of carbon fiber; 5-30 parts of flame retardant; the flame retardant is two or more compound flame retardants . The product is a product produced by molding the carbon fiber reinforced polycarbonate composite material. The carbon fiber reinforced polycarbonate composite material and its products of the present invention can not only ensure the flame retardancy and fluidity of the composite material, but also reduce the injection molding temperature of the composite material, so that the composite material can be applied to IMR molding, and the application of IMR film In high-end ultra-thin products, it can also injection mold structural parts with beautiful appearance.
Description
【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a carbon fiber reinforced polycarbonate composite material used in IMR molding and its products. 【Background technique】 [0002] In recent years, with the rapid development of smartphones, tablet computers, and notebook computers, the competition among many manufacturers has become increasingly fierce, and electronic products have gradually developed towards bright and colorful appearance, ultra-thin, and lightweight. [0003] IMR molding technology (in-mold transfer printing technology) technology can realize the integration of injection molding and decoration and the effect of one-time completion, and can also produce various special effects, which are more and more widely used in electronic products. [0004] However, the sheet material of IMR film is usually PET film. Due to the defects of PET film and ink that are not resistant to high temperature, IMR film is no...
