Abstract

The invention particularly relates to a damp-proof buffer material preparation method, and belongs to the technical field of functional material preparation. According to the invention, a waterproof buffer layer and a plant fiber foaming layer are adhered by using an adhesion layer as a middle layer, hot pressing is performed, and the surface of the obtained material is subjected to waxing treatment to obtain a damp-proof buffer material; the methoxyl in trimethylmethoxysilane is easily hydrolyzed, and can react with the amine substance in a protein adhesive to generate a methyl amino alkane substance, and the methyl amino alkane substance can be subjected to the potassium ions in plant ash to form potassium methyl silicate so as to easily improve the moisture-proof performance of the buffer material; the puffing of paper pulp fibers in foam can improve the buffer performance of the adhesion layer after being dried; during the film drawing, liquid paraffin is cross-linked with the hydroxyl in viscose fibers, such that the compactness of the liquid paraffin on the surface of the adhesion film can be improved so as to prevent the water absorption of the paper pulp fibers; and calciumoxide can form part of calcium carbonate in the environment of water and carbon dioxide so as to improve the use strength of the buffer material, such that the prepared material has wide applicationprospects.

Description

technical field [0001] The invention specifically relates to a preparation method of a moisture-proof buffer material, which belongs to the technical field of preparation of functional materials. Background technique [0002] With the rapid development of industrial production, vibration and noise have become serious problems in various fields: it will reduce operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, and endanger safety, especially for some electronic products. Threat to personal safety. Therefore, the development of cushioning materials with shockproof and noise reduction functions has become a major issue facing the industrial development of various countries. [0003] In the field of cushioning packaging, EPS (polystyrene foam) and other foam plastic products have become widely used cushioning materials in modern times due to their superior cushioning performance, shock absorption performance and ...
