Abstract

The invention provides a technology for processing a PMSA and PVC co-extruded plastic profile. The technology comprises the following steps: S1, raw material mixing: mixing a PMSA pigment, a PVC raw material, a stabilizer and a lubricant according to a ratio; S2, raw material drying: sequentially carrying out hot mixing treatment and cold mixing treatment on the mixed raw materials; S3, extrusion: carrying out extrusion operation on the raw materials through extrusion molding equipment; S4, cooling and shaping: cooling the extruded profile through a cooling mechanism, and continuously and automatically leading the cooled and hardened profile out of a machine head through traction equipment; and S5, cutting treatment: carrying out cutting treatment on the formed profile through cutting equipment. According to the technology for processing the PMSA and PVC co-extruded plastic profile, the profile produced by the cooling mechanism through a PMSA and PVC co-extrusion technology is bright in surface color, a co-extruded layer is high in hardness, not prone to fading and scratching and good in stripping degree, and the colored co-extruded layer and the PVC profile do not fall off.

Description

technical field [0001] The invention relates to the field of PVC profile molding, in particular to a PMSA and PVC co-extruded plastic profile processing technology. Background technique [0002] PVC profiles are industrial and domestic PVC products that are extruded at high temperature after adding various functional additives to PVC resin. The molding process of PVC profiles usually includes mixing of raw materials, drying, extrusion molding, cooling, pulling, cutting, etc. The pigments used in traditional PVC molding workpieces are easy to fade, the surface brightness is poor, and the peeling degree is poor and easy to fall off. [0003] Therefore, it is necessary to provide a PMSA and PVC co-extruded plastic profile processing technology to solve the above technical problems. Contents of the invention [0004] The invention provides a PMSA and PVC co-extruded plastic profile processing technology, which solves the problems of easy fading of pigments used in traditiona...
