Problems solved by technology

[0002] Polyvinyl acetate PVAC, as a commonly used water-based adhesive, is the most commonly used adhesive at present. Even if we are looking for ways to reduce production costs, the material is not the best choice; with the increasing awareness of people's health, the country's influence on sustainable development The supervision of the use of chemical raw materials is becoming more and more strict, and additives that are harmful to the human body and the biological environment, such as nonylphenol surfactants and dibutyl phthalate plasticizers, will be banned from use; such products Not only is it lacking in competitiveness, but also its market use is limited, so it cannot meet the requirements of products exported to Europe, America and other countries that require high environmental protection performance.
Compared with the existing technology, the new type of white latex uses relatively low-priced cornstarch as a substitute for the raw material, making the cost of the product lower than that of the traditional production process formula; but for environmental protection requirements, the existing white latex The content of the ingredients is harmful to the human body and the biological environment, and cannot meet people's requirements for the product

Abstract

The invention discloses an environmental-friendly white emulsion. The environmental-friendly white emulsion is prepared from the components in percentage by weight: 1.8-2.5 percent of polyvinyl alcohol PVA, 23-27 percent of vinyl acetate VAC, 0.3-0.8 percent of acrylic acid AA, 0.8-1.5 percent of acryl amide AM, 0.1-0.15 percent of ammonium persulfate, an anionic emulsifier A-102, alkyl polyoxyethylene ether LCN-287, a nonionic emulsifier, 5-7 percent of corn starch, a transparent powder, a plasticizer, 2.5-4 percent of diethylene glycol dibenzoate, 0.2-0.3 percent of preservative KSG-201, 0.1-0.2 percent of sodium hydroxide NaOH, 0.3-0.5 percent of methanol, 3-6 percent of functional filler, 0.15-0.3 percent of compound emulsifier and 56-58 percent of water. The environmental-friendly white emulsion is strong in the adhesive force and the adhesive strength, is low in the production cost and is good in the environmental protection performance.
