Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a reinforced spray-free non-scratch profile and its manufacturing method for the above-mentioned prior art. With regard to the co-extrusion process, the mixture formula of the PVC inner layer and the PMMA outer layer is improved at the same time, and the current co-extrusion process is eliminated. The defect that the strength of PVC is weakened during the extrusion molding process, so as to improve the material strength of the PVC inner layer and improve the overall strength of the final product

Abstract

The invention relates to an enhanced free-spraying profile without scratches. The profile is prepared by adopting a first mixture as an inner layer, and the second mixture as an outer layer through performing coextrusion molding; the first mixture is prepared from 100 parts of PVC (polyvinyl chloride), 20 to 30 parts of activated calcium carbonate, 5 to 10 parts of glass fibre, 2 to 4 parts of stabilizer, 0.1 to 2 parts of antioxidant, 5 to 10 parts of zinc stearate, 1 to 5 parts of mica powder, 2 to 5 parts of PE (polyethylene), 0.5 to 2 parts of tungsten oxytetrachloride, 4 to 8 parts of 2-pentene, 4 to 8 parts of cyclopentene and 2 to 10 parts of PMMA (polymethyl methacrylate); the second mixture is prepared from100 parts of PMMA, 20 to 30 parts of activated calcium carbonate, 1 to 4 parts of light stabilizer, 2 to 5 parts of PE, 0 to 4 parts of PVC and 15 to 30 parts of toner. According to the enhanced free-spraying profile without scratches and the preparation method of the enhanced free-spraying profile, the formula of the mixture of the PVC inlayer and the PMMA outer layer is improved, and the strength of the co-extruded profile PVE inner layer is improved, so that the whole strength of a final product is improved.

Description

technical field [0001] The invention relates to a plastic profile, in particular to a co-extrusion type of PVC and PMMA with higher strength. Background technique [0002] At present, the physical properties of the PVC profiles circulating in the market are poor, the tensile strength and impact strength are weak, and it is difficult to meet the requirements for the profile strength of different special purposes. [0003] A large number of plastic profiles are used in the structural components of home appliances. The traditional manufacturing process is to produce high-calcium PVC substrates by cold top method, spray the decorative surface manually, and then use them for structural assembly. This process has the following defects: the sprayed coating on the surface of the produced profiles is unstable, and the paint is easy to fall off; the surface hardness is not high enough, and scratches are prone to occur; during the manual painting process, the working conditions of the ...
