Color bending-resistant co-extruded section bar reflecting infrared rays and preparation method thereof

Abstract

The invention relates to the technical field of extrusion and processing of plastic products, in particular to a color bending-resistant co-extruded section bar reflecting infrared rays, which comprises, by weight part, 100 parts of acrylic acid-styrene-acrylonitrile copolymer or polymethylmethacrylate, 0-110 parts of polyvinyl chloride (PVC) and 5-16 parts of stabilizing agent. A color bending-resistant co-extruded granular material reflecting the infrared rays is obtained by adding a dry mixed potassium titanate crystal whisker material treated by a silane coupling agent, the color bending-resistant co-extruded granular material reflecting the infrared rays and a PVC dry material with a processing agent are prepared into the color bending-resistant co-extruded section bar reflecting the infrared rays through a special co-extruding mold, and color co-extruded doors and windows made of the color bending-resistant co-extruded section bars reflecting the infrared rays have the functions of reflecting the infrared rays, insulating heat and strengthening resistance to deformation. Under the action of the infrared rays, the thermal deformation degree of the color co-extruded doors and windows is reduced, the service life of the color co-extruded doors and windows is prolonged, and the reduction of the sealing performance of the color co-extruded doors and windows is avoided.

Description

technical field [0001] The invention relates to the technical field of extrusion processing of plastic products, and relates to a color co-extruded section material that reflects infrared rays and resists bending and a preparation method thereof. Background technique [0002] Colored co-extruded door and window profiles are generally co-extruded from two materials. The base material is PVC material. A layer of colored plastic is co-extruded on the surface facing the outdoor side by co-extrusion method. The two materials are heated and melted by a special co-extruded mold. They are compounded together under the condition of being made into colored co-extruded plastic door and window profiles of various colors. The thermal expansion of polymer materials is larger than that of metal materials, and the thermal expansion coefficient of polymer materials increases with the increase of temperature, and the thermal expansion coefficients of different polymer materials are also diffe...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a color co-extruded profile that reflects infrared rays and resists bending and its preparation method, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the existing problems. Colored co-extruded PVC door and window profiles, especially the doors and windows made of dark colored co-extruded PVC door and window profiles are bent and deformed by sunlight, which affects the sealing and service life.
