Abstract

The invention discloses an environment-friendly netted sandwich cloth base film and a preparation method thereof as well as netted sandwich cloth and a preparation method thereof. Wherein the environment-friendly netted cloth base film is prepared from the following components in parts by weight: 100 parts of PVC (Polyvinyl Chloride), 50 to 60 parts of polyester polyol, 0.5 to 1 part of ultraviolet absorbent, 0.15 to 0.5 part of antioxidant, 2.5 to 4 parts of barium-zinc stabilizer and 0.3 to 2 parts of processing aid; the molecular weight of the polyester polyol is 1000 to 1500. According to the netted cloth base film, polyester polyol is used as a plasticizer, the molecular weight of the polyester polyol is controlled to be 1000-1500, it can be guaranteed that solvent resistance is difficult to separate out, processing difficulty cannot be caused, carcinogenicity is avoided, and an antioxidant and a barium-zinc stabilizer are added to improve the processing stability.

Description

technical field [0001] The invention relates to the field of sandwich cloth, in particular to an environment-friendly cloth mesh base film and a preparation method thereof, and a cloth mesh and a preparation method thereof. Background technique [0002] The traditional sandwich cloth is a kind of material prepared by using mesh cloth as the base material, and then bonding PVC film on both sides of the mesh cloth. The sandwich cloth has the advantages of high tensile strength, good wear resistance and long service life, so its application field is very wide. [0003] Among them, inflatable products, trampoline products and other products are one of the main application fields of sandwich cloth. This type of product is mainly aimed at children, and the mesh fabrics currently on the market are generally added with DINP or DOP plasticizers to ensure that the PVC film can fit tightly with the mesh, but these two plasticizers belong to the category of o-phthalic acid. Children a...
