Emulsion polymerization is adopted to control the feeding mode during the polymerization process, and optimization is performed in terms of raw material components, proportions, etc. The concept of particle design is adopted to achieve optimal performance under a certain composition of raw materials. The production process is carried out under normal pressure, the maximum reaction temperature does not exceed 90 °C, intermittent operation, batch operation cycle within 8h.

Polymer emulsion type paper coating agent is acrylate copolymer emulsion, can be applied to the coating treatment of various grades of paper, the product uses the concept of particle design, in the same raw material composition, the pursuit of optimal coating performance The paper treated with this type of coated latex has a good stiffness, a full touch and a high gloss, and the coated paper does not turn yellow.

Two-component high-end puzzle glue The main agent is a polymer emulsion, and the curing agent is a brown to brownish yellow liquid. The composite adhesive does not contain toxic contaminants such as formaldehyde, benzene, toluene, xylene, and heavy metals. The adhesive has low cost and can be used for cold pressure splicing of high-grade water resistant sheets, and is an indispensable material for high-grade furniture production plants.

The production process of the adhesive is simple, and the cold-pressed panel can withstand the harsh conditions of cold water soaking, boiling water boiling, high-temperature baking and other harsh conditions. The main polymer emulsion has a solid content of 50% to 55%.

Hollow Polymer Particles The polymer latex particles with a hollow structure prepared by an emulsion polymerization method can improve the hiding power of the coating, promote the lightening of the coating, and can also be applied to paper coating to improve the quality of paper products and reduce coating. The amount of agent reduces the cost of coated paper/paint. When this technology is used to produce hollow polymer particles, the particle size of the latex particles can be controlled to 400 to 1200 nm and the hollow diameter to 200 to 400 nm. The polymer emulsion has a solid content of about 30%.

Equipment investment is about 100,000 yuan and the production capacity is 1000 t/a.
