Acrylates waterborne coating gum and production method thereof

Abstract

The invention provides an acrylates waterborne coating gum, belonging to the technical field of textile printing and dyeing agents. The acrylates waterborne coating gum mainly comprises the following components by mass percent: 5-10% of ethyl methacrylate, 10-20% of polyacrylic ammonia ester, 1-3% of acrylamide, 5-15% of methacrylic acid dimethyl ammonia ethyl ester, 5-10% of acetone, 1-2% of a conditioning agent and the balance of a diluent. The acrylates waterborne coating gum is good in waterproof property and moisture permeability, soft, wear resistant and low temperature resistant; and a compact firm film can be formed on the surface of the textile, so that the adhesive property is high; and the utilization rate of the raw materials is high, and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing materials, in particular to an acrylic ester water-based coating glue with good waterproof and moisture permeability, softness, abrasion resistance and low temperature resistance and a production method thereof. Background technique [0002] Fabric coating glue, also known as fabric coating finishing agent, is a polymer compound that is evenly coated on the surface of the fabric. He forms one or more layers of film on the surface of the fabric through adhesion, which can not only improve the appearance and style of the fabric, but also increase the function of the fabric, making the fabric waterproof, water pressure resistant, breathable and moisture permeable, flame retardant, antifouling and shading Reflection and other special properties. As early as in ancient China more than 2,000 years ago, fabric coating adhesives were used, mostly natural compounds such as raw lacquer ...

Problems solved by technology

[0003] In modern times, a variety of synthetic polymer coating adhesives with superior performance have appeared. The original product has the disadvantage of being only waterproof and airtight, which makes the coated fabric feel stuffy and poor in comfort when worn, which limits its application range. In order to improve the air and moisture permeability of coating adhesives, since the 1970s, people have developed some new coating adhesives through chemical structure modification and changing coating processing methods. Acrylic fabric coating adhesives are currently commonly used One of the most popular coating adhesives, the processed fabrics are soft, light-resistant, and weather-resistant. It is widely used in various clothing and decorative materials. According to its synthesis method and product properties, this type of coating adhesive has solvent-based and Emulsion type: solvent-based products have strong adhesion to fabrics, and can form a dense and firm film on the surface of the fabric, but because they contain organic solvents, they will cause environmental pollution, cause fires, and the cost of solvent recovery is very high, and the cost is high; while emulsions Emulsifier residues on molded surfaces can cause water leakage and dust pickup of processed fabrics

In addition, emulsion-type products have low adhesion to fabrics, and the film formation is not as dense as solvent-based products, and their wear resistance and cooling performance are also poor.
