Abstract

A production process of high-flame-retardant and oil-resistant PVC particles include the following steps of preliminary preparation, raw material preparation, filler preparation, mixing, extrusion, granulation and qualification test. Raw materials are composed of, by mass, 45-55 parts of polyvinyl chloride resin, 20-30 parts of a plasticizer, 8-10 parts of a filler, 5-8 parts of nano rubber particles, 3-5 parts of a stabilizer, 3-5 parts of a fire retardant, 3-5 parts of a lubricant Hst1, 1-2 parts of calcium oxide, 1-2 parts of nano calcium carbonate, 1-2 parts of a viscosity reducer, and 1-2parts of other additives P-830. The production process of the high-flame-retardant and oil-resistant PVC particles is simple, the compatibility of the substances is significantly improved through thefiller, the oil resistance and cold resistance of PVC are improved through the nano rubber particles, the flame resistance of PVC is improved through the fire retardant, the formula of the raw materials is reasonable, all components are good in compatibility, play their own roles and have synergistic effects, and the prepared PVC particles have good flame resistance, oil resistance, cold resistance, mechanical properties and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of PVC preparation technology, and in particular relates to a production technology of highly flame-retardant and oil-resistant PVC particles. Background technique [0002] Polyvinyl chloride (collectively referred to as PVC) is a general-purpose thermoplastic material that is most widely used in the world and is the first to complete industrialization. According to statistics, the global production capacity of PVC materials has exceeded 33.13 million tons in 2001, and the current annual growth rate of PVC production capacity is still as high as 4%. PVC plastic has the advantages of low cost, short construction period, corrosion resistance, and good comprehensive performance. Its intensive production technology and close relationship with the chlor-alkali industry make PVC industry and automobile decoration, architectural membrane materials, petroleum industry and mechanical electronics. Industry and other ...
