AI Technical Summary

Problems solved by technology

[0002] At present, floor felt is mainly used as the base material of plastic floor and wallpaper. It has the characteristics of uniform thickness, good dimensional stability, no deformation at high temperature, low elongation, high tensile strength, no warping, no mildew, and easy impregnation; The soft plastic floor made of glass fiber floor mat as the base material has a smooth and crisp appearance, no shrinkage and deformation, and bright colors. After further processing, this product can be made into various colored veneer materials. It is an ideal material for decorating high-end hotels and restaurants. Most of the traditional floor mats have the problem that the binder of the product contains formalde

Example

[0022] Example 1. Preparation of formaldehyde-free ultra-thin fiberglass floor mat, the steps are as follows:

[0023] (1) Put ionized water in the mixer first, then add hydroxyethyl cellulose to make the water viscosity 15cp, then add dispersant 5040 and defoamer to make the content of dispersant 5040 600ppm, defoamer The content is 500ppm, and the defoamer is TS-603 defoamer from Guangzhou Tianling Silicone Co., Ltd.;

[0024] (2) Add the ultra-fine alkali-free glass fiber chopped yarn into the mixer and stir and disperse for 1 hour. The weight ratio of the fine alkali-free glass fiber chopped yarn to the ionized water in the mixer is 1:4; ultra-fine alkali-free glass fiber The length of glass fiber chopped yarn is 10mm and the diameter is 9μm;

[0025] (3) Spread the ultra-fine alkali-free glass fiber chopped yarn after stirring and dispersing on the mesh belt. After dehydration, it is poured with acrylic adhesive and dried to become the finished formaldehyde-free ultra-thin glass f

Abstract

The invention relates to a formaldehyde-free super-thin glass fiber floor felt, which is characterized by being prepared by adhering super-thin alkaline-free glass fiber chopped yarns and an acrylic acid adhesive by a weight ratio of (2:1) to (5:1) and drying, wherein the super-thin alkaline-free glass fiber chopped yarns are 6-18 mm in length and 8-10 micrometers in diameter; the acrylic acid adhesive comprises the following ingredients in percentage by weight: 65-80 percent of an environment-friendly emulsion type acrylic ester adhesive, 15-30 percent of modified polyvinyl acetate type white glues, 0.03-0.09 percent of a silane coupling agent KH-550 and 3-6 percent of hydroxyethyl cellulose; the solid content of the environment-friendly emulsion type acrylic ester adhesive is 43-55 percent by weight; the solid content of the modified polyvinyl acetate type white glues is 50-55 percent by weight. The invention also relates to a preparation method of the formaldehyde-free super-thin glass fiber floor felt. The formaldehyde-free super-thin glass fiber floor felt and the preparation method thereof disclosed by the invention have the advantages of no formaldehyde and low air permeability.
