Abstract

The invention discloses a method for producing a polyvinyl chloride plain film. The method is characterized by comprising the following steps: using 100 parts of PVC resin, 40-60 parts of a tackifier, 20-40 parts of a heat stabilizer, 50-200 parts of a strengthening agent, 10-20 parts of reinforced resin, 0.5-1.5 parts of a lubricant and 4-6 parts of an accelerant as raw materials to form a formula, and performing high-speed hot mixing, low-speed hot mixing, extrusion, open milling, calendering, cooling, molding, cutting and packaging to produce the polyvinyl chloride plain film. According to the method, the technology is simple, and the manufactured polyvinyl chloride plain film has good quality; the method disclosed by the invention uses a special formula; the film material is uniform to plasticize, flawless, good in toughness, resistant to impact, flame-retardant, good in low temperature performance, resistant to ageing and long in service life.

Description

technical field [0001] The invention relates to a manufacturing method of a polyvinyl chloride flat sheet. Background technique [0002] The natural color of polyvinyl chloride is light yellow translucent and shiny. Transparency is better than polyethylene and polystyrene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. Hard products have higher hardness than low-density polyethylene. , and lower than polypropylene, there will be whitening at the inflection. Common products: plates, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, etc. Polyvinyl chloride is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. [0003] Polyvinyl chloride (PVC) flat sheet is the base material for the production of various shower panels, and is also used for other plastic products and secondary processing molding sheets. The e...
