Abstract

The invention relates to a preparation method for a PVC (polyvinyl chloride) pipe material with a stainless steel effect. The preparation method comprises the following steps: preparing the raw materials in parts by weight: 100 parts of PVC, 15-30 parts of stainless steel powder, 8-15 parts of dispersing agent, 8-18 parts of whisker, 5-15 parts of styrene butadiene powder rubber, 1-3 parts of coupling reagent, 1.5-3 parts of heat stabilizer and 0.5-1.5 parts of lubricating agent; distributing the coupling reagent to the surface of the whisker, drying, and cooling to obtain the modified whisker; adding the stainless steel powder into a dispersing agent solution to obtain modified stainless steel powder solution; injecting the modified stainless steel powder solution while the PVC, the styrene butadiene powder rubber, the heat stabilizer and the lubricating agent are stirred and mixed, and drying and cooling to obtain premixing raw materials; adding the premixing raw materials and the modified whisker into an extruder to carry out extrusion and granulation to obtain the PVC pipe material. The PVC pipe material prepared with the preparation method has he advantages of good stainless steel effect, good stretching level and toughness and good heat stability.

Description

technical field [0001] The invention relates to a preparation method of a PVC pipe with stainless steel effect, and belongs to the technical field of PVC pipe preparation. Background technique [0002] Polyvinyl chloride, referred to as PVC, is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. PVC pipes have good flame retardant effect , strong acid and alkali resistance, high structural strength, good electrical insulation and other excellent physical and chemical properties, is currently one of the most widely used plastic pipes on the market, in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather , pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. are widely used. [0003] PVC pipes are divided into PVC water supp...
