Abstract

The invention discloses a high-barrier biodegradable mulching film and a preparation method thereof. The high-barrier biodegradable mulching film is composed of the following components in parts by weight: 20-50 parts of propylene polycarbonate, 30-60 parts of linear low density polyethylene, 2-3 parts of 2,4-dihydroxy benzophenone, 2-2.5 parts of bitetradecyl alcohol esters, 20-57 parts of poly-3-polyhydroxybutyrate-co-3-hydroxyhexanoate, 15-55 parts of polybutylene terephthalate, 13-32 parts of poly(butylene succinate), 3-10 parts of glycidyl acrylate grafted polyethylene, 0.5-1.5 parts of ahindered amine light stabilizer, 0.2-1.5 parts of dimethyl tin isooctyl dithioacetate, 10-30 parts of a filler and 0.2-1 part of a cross-linking agent. The high-barrier biodegradable mulching film disclosed by the invention has excellent barrier property and biodegradable property.

Description

technical field [0001] The invention relates to a high-barrier biodegradable mulch film and a preparation method thereof. Background technique [0002] At present, the performance of biodegradable mulch film is lower than that of PE film under the same circumstances, among which the tear strength and barrier performance are the most obvious. The conventional solution is to make up for the above defects by increasing the thickness and adding process links, but the high cost of the mulch obtained by such methods is not conducive to popularization and application. Contents of the invention [0003] The purpose of the present invention is to provide a high-barrier biodegradable mulch film and a preparation method thereof. The high-barrier biodegradable mulch film has good barrier property, high tear strength and low cost. [0004] In order to achieve the above object, the technical solution of the present invention is to design a high-barrier biodegradable mulch film, which c...
