Abstract

The invention discloses a filling master batch for a transparent film, and belongs to the field of a plastic additive. The master batch consists of the following raw materials in percentage by mass: 80-85% of barium sulfate, 14-19 parts of linear low density polyethylene (LLDPE) and 0.5-1% of silicone, wherein the barium sulfate is more than 98% in powder whiteness and is produced by virtue of a precipitation method, and the average particle size of the barium sulfate is 0.2-0.25 micron; the low molecular weight organic matter of the silicone is less than or equal to 0.15%. Furthermore, the invention discloses a preparation method of the master batch, and the preparation method comprises steps of selecting raw materials, measuring, mixing the materials, extruding, cooling, granulating and packaging. The master batch disclosed by the invention has the advantages of being good in dispersibility, high in transparency, and capable of fundamentally reducing production cost and guaranteeing product quality.

Description

technical field [0001] The invention relates to a filler masterbatch and a preparation method thereof, in particular to a filler masterbatch for a transparent film and a preparation method thereof, belonging to the field of plastic additives. Background technique [0002] In 2012, my country produced and used 2.2 million tons of agricultural film, of which 1 million tons were transparent shed film, and the rest was plastic film. The average annual growth rate of agricultural film remained at 7%. However, the production of existing transparent films cannot be filled with masterbatches. If general fillers are added, the brightness, light transmittance, and strength of the transparent film will be greatly reduced, and it may even be unusable. According to statistics, one ton of synthetic resin requires three tons of petroleum. If 10% of inorganic powder can be added as a filler in transparent film products, taking 2012 as an example, 100,000 tons of resin consumption can be red...
