High-tear-strength water-resistant non-woven fabric grinding material as well as preparation method and application thereof

Abstract

The invention provides a high-tear-strength water-resistant non-woven fabric grinding material as well as a preparation method and application thereof. The grinding material comprises a base material and pulp, wherein the base material is made of nylon fibers with excellent wear resistance; the nylon fibers are processed into a three-dimensional net-shaped structure through an air-laid machine and a needling machine; and the pulp comprises polyurethane cotton spraying pulp, polyurethane prime pulp and polyurethane composite pulp. According to the high-tear-strength water-resistant non-woven fabric grinding material as well as the preparation method and the application thereof provided by the invention, a novel adhesive and a mature production process are introduced, and the defects that an existing product is good in adhesive property, low in tearing strength and low in abrasion resistance are overcome. The used polyurethane is correspondingly adjusted according to the process characteristics of different working sections. Finally, a polyurethane type non-woven fabric grinding product with high tear strength, strong wear resistance and water resistance is produced. The polishing cost is reduced, production and use are more environmentally friendly, and the environmental protection pressure is relieved. The application of polyurethane in the non-woven fabric grinding industry is innovated.

Description

technical field [0001] The invention relates to the field of non-woven abrasive materials, in particular to a water-resistant non-woven abrasive material with high tear strength and its preparation method and application. Background technique [0002] Polyurethane adhesives are more and more sought after by people because of their adjustable soft and hard segments, strong wear resistance, no by-products in the reaction, good water resistance, and strong mechanical properties. The use of polyether polyurethane as an adhesive for non-woven fabrics can achieve good bonding performance between fibers and sand, and make the product have high tear strength and high water resistance. [0003] The scouring pad, one of the current non-woven abrasive products, uses phenolic spray cotton glue, and the base glue and surface glue use phenolic and epoxy-based adhesives, which make the product have good bonding performance but are brittle. Moreover, polyurethane has poor water resistance ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention is to solve the problem of strong brittleness of the product, low tear strength and the water resistance of polyurethane by using epoxy, phenolic resin, etc. to do glue bonding and acrylic acid, phenolic resin, etc. A high tear strength water-resistant non-woven abrasive material and its preparation method are proposed
