Self-crosslinking styrene-acrylic emulsion for producing water-resistant batten lines and preparation method of self-crosslinking styrene-acrylic emulsion

Abstract

The invention discloses a self-crosslinking styrene-acrylic emulsion for producing a water-resistant batten line and a preparation method thereof, and the self-crosslinking styrene-acrylic emulsion is prepared from the following raw materials in parts by weight: 1.5-4 parts of an anionic emulsifier, 0.1-2 parts of a nonionic emulsifier, 2-5 parts of acrylic acid, 3-6 parts of hydroxyethyl acrylate, 15-20 parts of butyl acrylate, 16-18 parts of styrene, 1-3.5 parts of potassium persulfate and 0.5-3 parts of tert-butyl hydroperoxide. The invention relates to a high-temperature-resistant paint, which is prepared from the following raw materials in parts by weight: 0.3 to 2 parts of sodium formaldehyde sulfoxylate, 0.3 to 1.2 parts of silicon monomer, 1.5 to 3 parts of ammonia water, 0.05 to 0.15 part of emulsified silicone oil defoaming agent, 0.08 to 0.26 part of long pine preservative, 0.05 to 0.5 part of dispersing agent, 0.05 to 0.5 part of wetting agent and 55 to 70 parts of deionized water. A novel safe and environment-friendly non-APEO emulsification system is adopted, a crosslinking monomer is prepared by pairing hydroxyethyl acrylate and acrylic acid, traditional N-hydroxymethyl acrylamide glue capable of releasing formaldehyde is not used, an advanced core-shell emulsion polymerization process is adopted, and the prepared styrene-acrylic emulsion is widely applied to batten line production enterprises.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a self-crosslinking styrene-acrylic emulsion for producing water-resistant wood strips and a preparation method thereof. Background technique [0002] At present, the decoration of home and office environment is changing with each passing day. Among them, the wooden strip is one of the widely used ones. It has many superior performances such as beautiful appearance, stable size, low price, and full environmental protection. At present, one of the raw materials required for the production of this product, acrylic emulsion, is produced by small-scale chemical companies, and its technology needs to be greatly improved in performance and stability compared to the original product. [0003] In my country's current acrylic emulsion production enterprises, the emulsifiers used are nothing more than amino acid polyoxyethylene ether and its sulfonate or sulfate derivatives, such as OP-1...

AI Technical Summary

Problems solved by technology

1. The use of traditional APEO-containing emulsifiers will cause harm to the human body and environmental pollution;

2. The use of N-methylolacrylamide will release formaldehyde, causing pollution to the indoor environment;

3. The imperfection of the polymerization process will make the quality of the emulsion product not stable enough;

4. The one-step polymerization process of the pre-emulsion has certain deficiencies in the physical and chemical indicators of the film, especially the addition of film-forming aids to the hard emulsion, which increases the VOC content
