[0002] The field of hot glue between non-woven fabrics and wall coverings has attracted more and more attention. The existing non-woven fabrics and wall coverings are bonded with liquid glue, that is, a layer of liquid glue is applied on the surface of the non-woven fabrics, and then glued on the surface of the non-woven fabrics. Paste a layer of hot melt adhesive on the non-woven fabric and heat it on the wall with an iron. This hot glue process has the following disadvantages: 1. Liquid glue is used between the non-woven fabric and the wall covering. When heated, it is easy to produce odor and poor environmental protection. , the viscosity is low, and the liquid glue is easy to penetrate into the wall covering throu

Abstract

The invention discloses a non-woven fabric coated with a hot melt glue and a hot gluing process of the non-woven fabric. The hot melt glue is pasted and covered on the surface of the non-woven fabric;a raw material of the hot melt glue is EVA (Ethylene-Vinyl Acetate) particles; the EVA particles are prepared from the following components in parts by weight: 50 to 60 parts of ethylene-vinyl acetate (EVA), 30 to 60 parts of modified EVA, 15 to 20 parts of tackifying resin, 5 to 10 parts of plasticizer, and 0.1 to 5 parts of function additive. The hot gluing process of the non-woven fabric coated with the hot melt glue comprises the following concrete steps of (1) building low-temperature hot melt glue membrane production equipment; (2) preparing the EVA particles; (3) running the non-wovenfabric on production equipment; (4) laying off the EVA particles; (5) casting, extruding, pressing, covering and sizing; (6) cooling and rolling. The non-woven fabric coated with the hot melt glue andthe hot gluing process of the non-woven fabric provided by the invention have the following advantages that the time and the labor are saved, the environmental protection property is improved, the width of a hot melt glue membrane is ensured to exceed 2m, and the product stability and the precision of the thickness uniformity are improved.
