Abstract

The invention relates to a plastic profile with a surface matte effect and a production method thereof. The production method comprises the following steps that: a matrix polymer and a plastic additive are mixed into a matrix mixing material, a surface-layer polymer and an additive are mixed into a surface-layer mixed material, and the matrix mixed material and the surface-layer mixed material are compounded and co-extruded to be molded and then are sand-blasted to obtain the plastic profile, wherein the surface-layer polymer is poly (methyl methacrylate), an acrylonitrile-styrene-acrylic ester copolymer, an acrylonitrile-butadiene-styrene copolymer, polycarbonate and the like, the thickness of the surface-layer material is 0.01-1 mm, and the matrix polymer is polyvinyl chloride, an acrylonitrile-butadiene-styrene copolymer, or polycarbonate and the like. The product provided by the invention has high surface hardness, strong adhesion, and a soft and delicate appearance like brocade, is fully comparable to a matte surface aluminum profile in the decorative effect, and can meet the demands of refrigerators, air conditioners, washing machines and other household appliance industries, and building materials, automobiles and other industries. The production process provided by the invention is simple and non-polluting.

Description

technical field [0001] The invention relates to a plastic profile with a frosted effect on the surface and a production method thereof, belonging to the technical field of plastic surface coating and surface decoration. The invention can provide a new type of decorative plastic profile with a frosted effect for industries such as household appliances, automobiles, and building materials. Background technique [0002] Aluminum alloy profiles can form various colors and various effects through surface decoration. Among them, the products with frosted surface effect avoid the disadvantage of light interference caused by bright profiles under certain conditions. In recent years, they have become very popular in the market and are widely used in home appliances, construction, automobiles and other fields. Although aluminum alloy products have beautiful appearance and good dimensional stability, they have high density and poor heat preservation effect. The production process consu...
