Abstract

The invention relates to the field of mulching film materials, and discloses a weather-proof resin master batch for agricultural plastic mulching film synthesis and a preparation method thereof. The weather-proof resin master batch is prepared from 45-65 parts of linear low density polyethylene powder, 15-25 parts of low density polyethylene powder, 4-8 parts of high density polyethylene powder, 1-2 parts of an antioxidant, 0.5-1 part of a light stabilizer, 0.5-1 part of an ultraviolet light absorber, 4-6 parts of acrylic acid, 4-8 parts of a sodium hydroxide water solution, 0.5-1.5 parts of sea-foam stone powder, 0.5-1.5 parts of konjac glucomannan, 0.02-0.04 part of potassium persulfate, 0.04-0.06 part of aluminum chloride, 0.01-0.03 part of N,N' methylene-bisacrylamide, 0.1-0.3 part of sodium bicarbonate, 0.5-1.5 parts of sodium carboxymethyl cellulose and 1-2 parts of polyethylene wax. The weather-proof resin master batch has the good light resistance and heat resistance and excellent tensile property, and is capable of being repeatedly recycled and long in service life.

Description

technical field [0001] The invention relates to the field of mulch materials, in particular to a weather-resistant resin masterbatch for synthesizing agricultural mulch and a preparation method thereof. Background technique [0002] my country is a traditional large agricultural country, and there is a huge demand for agricultural mulch every year. However, most of the current mulch films have poor weather resistance, and are prone to aging and cracking after being exposed to wind, sun, and rain for a long time. [0003] The Chinese invention patent with application number 201510186686.2 discloses a plastic mulch film with good weather resistance, which is made of the following raw materials in parts by weight: EPDM 2-8 parts, white oil 5-9 parts, polyvinyl chloride 7-10 parts, 1-5 parts of carboxymethyl fatty amine, 4-11 parts of vinyl acetate, 9-14 parts of stearic acid, 1-4 parts of nano-Cr-W alloy powder, 4-9 parts of aluminum-based nanomaterials, 1 part of chromium oxi...
