Abstract

The rolled soft polyvinyl chloride film consists of basically polyvinyl chloride resin in 100 portions, heat stabilizer 2-4 portions, plasticizer 20-40 portions, lubricant agent 0.5-1.0 portions, andnanometer material 5-20 portions. Based on the requirement in service performance, the inorganic nanometer material and soft polyvinyl chloride are ground, high speed mixed, internally mixed, openlymixed and rolled, so that the nanometer material is dispersed in soft polyvinyl chloride substrate to obtain the inorganic nanometer material modified rolled soft polyvinyl chloride film, which has good plasticizer migration resistance, high strength and good temperature performance.

Description

technical field [0001] The invention relates to a modified plastic and a processing method thereof, in particular to a soft polyvinyl chloride calendered film and a manufacturing method thereof. Background technique [0002] At present, according to the national standard GB / T3830-94, the main raw materials for producing soft PVC calendered film are polyvinyl chloride resin, plasticizer, heat stabilizer, and inorganic filler, among which the inorganic filler generally adopts micron-sized calcium carbonate. Using micron-scale calcium carbonate to fill the modified soft polyvinyl chloride calendered film has the advantages of low price and easy control of the production process, such as Chinese patent application No. 85106222, and according to the first issue of "China Plastics" No. It is recorded on the page that ultra-fine micron-sized calcium carbonate has a certain strengthening effect on soft PVC. However, the soft PVC calendered film modified by micron-sized calcium carb...
