Abstract

The invention discloses a spraying-free high-flowability high-impact flame-retardant PC material with metal texture as well as a preparation method and application of the material. The material is prepared from 55 to 89 parts of PC resin, 1 to 25 parts of metal powder master batch, 5 to 10 parts of halogen-free flame retardant, 5 to 10 parts of flexibilizer, 0.1 to 0.5 part of antioxidant and 0.2 to 2 parts of lubricant; wherein the metal powder master batch is metal powder subjected to coating treatment by an MAH-St-MMA copolymer. The compatibility between the metal powder and PC is improved through MAH-St-MMA, the material performance and the metal texture are improved, and the technical problem that in the prior art, the flowability, the impact property and the flame retardant property of a metal texture PC material cannot be considered at the same time is solved through cooperative use of high-flowability PC, the metal powder master batch, the flexibilizer and the halogen-free flame retardant; meanwhile, the material has a good appearance effect, high flowability, impact resistance and flame retardance, is easy to form and meets the requirements of wall switches.

Description

technical field

[0001] The invention belongs to the technical field of materials, and relates to a flame-retardant PC material and its preparation method and application, in particular to a high-flow, high-impact flame-retardant PC material with metallic texture and spray-free, as well as its preparation method and application. Background technique

[0002] The metal-textured spray-free plastic is a new type of functional material. By adding and blending metal pigments into the plastic substrate, metal-textured parts can be prepared at one time. Compared with the traditional process of injection molding and then spraying, spray-free plastics do not require complicated spraying processes, and can be formed at one time. Organic solvents are safer and more environmentally friendly, in line with the development trend of energy conservation and environmental protection, and have begun to be widely used in automotive accessories, household appliances and other fields.
