Problems solved by technology

However, this invention patent uses PC resin as the carrier, and amino compounds or novolac resins as the flame retardant synergist. Such carriers and flame retardant synergists are prone to yellowing under ultraviolet light and have extremely poor weather resistance; the flame retardant synergist The agent is prone to yellowing when it is processed at a temperature greater than 230°C, which makes it difficult to control the color difference of injection molded parts, especially plastic parts such as large air conditioner casings, which are more likely to appear yellow streaks, etc.

Abstract

The invention discloses an ABS slow-burning color master batch with high weather resistance and high temperature resistance and belongs to the technical field of plastics colouration. The ABS slow-burning color master batch is composed of the following ingredients (by weight): 10-35% of polyamide, 10-70% of ABS, 0.001-75% of a toner, 1-20% of a weather resistance agent, 2-30% of a fire retardant,0.05-3% of an antioxidant, and 0-10% of a dispersant. The color master batch has high temperature resistance. During injection molding of a large product, the product has uniform color and there is noyellow line or yellowing problem. meanwhile, when the color master batch is used for coloring of an ABS product, burning rate of the product can meet the requirement of UL94HB, and the product also can meet the following requirements: the fire retardant is halogen-free, and the chromatic aberration change (Delta E) is less than or equal to 8 when the product is under ultraviolet radiation at 303nm for 96 H. The ABS slow-burning color master batch of the invention has good compatibility with ABS, has excellent color dispersion and has little influence on impact strength of the product.

Description

technical field [0001] The invention belongs to the technical field of plastic coloring, and in particular relates to a high-weather-resistant and high-temperature-resistant ABS slow-burning color masterbatch. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene. Currently, ABS production methods include copolymerization, emulsion grafting and blending. By adjusting the ratio of the three monomers, resins with different properties and grades can be prepared. ABS resin is non-toxic and odorless, not only has excellent mechanical properties of toughness, hardness and rigidity balance, but also has good chemical resistance, dimensional stability, surface gloss, low temperature resistance, coloring performance and other properties. As one of the five general-purpose engineering plastics with the largest output and widest application, it is widely used in many fields such as automobiles, appliances, electronic devices, and household app...
