Abstract

The invention provides a PVC extrusion column and a molding technology thereof. The PVC extrusion column comprises the following raw materials in parts by mass: 100 parts of polyvinyl chloride (PVC) resin, 70-110 parts of calcium carbonate (CaCO3), 7-14 parts of a PVC anti-impact processing modifier (ACM), 0.2-0.5 part of polyethylene (PE) wax, 1-3 parts of calcium stearate (Ca(Sa)2), 0.5-1 part of zinc stearate (Zn(St)2), 0.02-0.1 part of organic tin and 0.04-0.08 part of a toner. According to the provided PVC extrusion column and the molding technology thereof, the column extruding molding technology relatively well solves the problems that a sprayed column is server in environment pollution, low in finished-product qualified rate, complex in preparation technology and the like. Additionally, Ca(St)2, Zn(St)2 and organic tin are taken as PVC heat stabilizers, low-price PVC resin and CaCO3 are taken as the main raw materials, and the column extruding molding technology is employed, so that the PVC extrusion column profiles are prepared.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PVC extruded column and a molding process thereof. Background technique [0002] Spray-coated column means that after the column profile is obtained through the extrusion molding process, the surface is sprayed to change its original surface color, roughness, etc. It is called spraying column profile. At present, due to the low surface hardness and non-wear resistance of spray-coated column profiles, the coating is easy to fall off during long-term use, which is not suitable for the needs of social development. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and provide a PVC extruded column with low production cost, good mechanical properties and usable performance and its molding process. [0004] A PVC extruded column, its raw materials are calculated in parts by mass, including: [0005] ...
