Embodiment Construction

[0015] High weather resistance and color-changing wood-like plastic profiles, the plastic profile raw materials are mixed resin particles composed of ASA resin particles and ABS resin particles and inorganic pigments for extrusion molding.

[0016] 100 parts of mixed resin particles composed of the ASA resin particles and ABS resin particles, 0.32 parts of inorganic pigment carbon black, 0.52 parts of carbon oxide, 0.5 parts of titanium yellow, and 0.21 parts of titanium oxide.

[0017] Among the 100 parts by mass of the ASA resin particles, the mixing amount of the ABS resin particles is 1.6-3.8 parts, and the mixing amount of the inorganic pigment is 1.2-6.3 parts.

[0018] High weather resistance and color-changing wood-like plastic profile preparation process, (1) Mixed resin particles composed of ASA resin particles and ABS resin particles and inorganic pigments are used to prepare molding materials, and the temperature is extruded at 178-202 degrees;

[0019] (2) The mel...

Abstract

The invention discloses a highly-weatherable allochroic synthetic wood plastic section bar. The raw material of the plastic section bar is obtained through extruding mixed resin particles and an inorganic pigment, and the mixed resin particles are composed of ASA resin particles and ABS resin particles. The disadvantages of the prior art are overcome in the invention, the weatherable allochroic synthetic wood plastic section bar has a bright color and pattern for a long term, can be widely used in floors, window frames, furniture and guardrails, and has the advantages of strong wood sensation, synthetic wood texture appearance, and simple production technology.

Description

[0001] technical field [0002] The invention relates to the technical field of PVC plastic profiles, in particular to wood-like plastic profiles with high weather resistance and discoloration and a preparation process thereof. [0003] Background technique [0004] The existing ASA material is not fully mature, especially the plasticizing process in the co-extrusion machine has strict requirements on the process; the products of different machines are prone to obvious color differences, and even the wood grain effect disappears. It is difficult to keep the color and grain of the ASA material consistent. Its scope of application is narrow and not beautiful enough. Contents of the invention [0005] The object of the present invention is to provide high weather resistance and color-changing wood-like plastic profiles, which overcome the deficiencies in the prior art. The weather-resistant wood-like plastic profiles have bright colors and patterns for a long time, and are ...
