Problems solved by technology

Since the molecular bonds of PVC contain chlorine, which is easy to age and decompose, it is prone to aging, discoloration and deformation under the condition of long-term storage.
The traditional method is to add a large amount of weather resistance agent to the whole system or co-extrude a layer of ASA resin on the surface of the profile, but the cost is very high

Abstract

The invention discloses a PVC (polyvinyl chloride) colorful coextruded material and an application thereof, and the colorful coextruded material comprises the following materials in parts by weight: 70-100 parts of PVC resin, 4.0-7.5 parts of heat stabilizer, 0-8.0 parts of processing agent, 0-8.0 parts of flexibilizer, 0-15 parts of filler, 0.3-2.0 parts of lubricating agent, 0.1-1.5 parts of weather-resistant agent, and 0.1-5.0 parts of pigment. By adopting the PVC colorful coextruded material disclosed by the invention, surface co-extrusion layers with bright colors, good weather resistance and excellent mechanical property can be formed in the products such as different formula systems of hard PVC plastic materials, PVC doors and windows and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PVC color co-extrusion material and its application. Background technique [0002] In recent years, PVC plastic doors and windows, PVC plastic profiles, etc. have been widely popularized and applied in China. Since the molecular bonds of PVC contain chlorine elements that are easy to age and decompose, aging, discoloration, and deformation are prone to occur under long-term storage conditions. The traditional method is to add a large amount of weather resistance agent to the whole system or co-extrude a layer of ASA resin on the surface of the profile, but the cost is very high. Therefore, it is meaningful to develop a profile surface coextrusion material with qualified performance and low cost. Contents of the invention [0003] One object of the present invention is to provide a PVC color co-extrusion material. [0004] Another object of the present...
