High-standard formaldehyde-free glue and preparation method thereof

Abstract

The invention relates to a high-standard formaldehyde-free glue and a preparation method thereof. The high-standard formaldehyde-free glue is prepared from the following raw materials in percentage by weight: 3 percent of water soluble polyvinyl alcohol, 1 percent of water-retaining agent, 0.1 percent of edible antifoaming agent, 0.1 percent of edible preservative, 0.1 percent of dispersing agent, 1 percent of dispersible emulsoid powder, 0.01 percent of thickener and 94.69 percent of purified water. The preparation method comprises the following steps of mixing the raw materials in proportion, and uniformly stirring the raw materials through a stirring machine; and after uniformly stirring the raw materials, grinding the uniformly stirred mixture into the glue through a stuff grinder. The preparation method has the beneficial effects that temperature raising is not required in the whole preparation process, so that the natural components of a raw stock are kept, and meanwhile the phenomena of environment pollution and energy resource waste which are caused by temperature raising are avoided. The high-standard formaldehyde-free glue is high in bonding degree, corrosion resistant and anti-crack.

Description

technical field [0001] The invention relates to a glue, in particular to a high-standard formaldehyde-free glue and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy, people's living standards are also constantly improving. While living standards are improving, people's requirements for living conditions and the environment are also getting higher and higher. Not only must be green and environmentally friendly, but also multi-functional ,diversification. As a result, people have higher and higher requirements for the quality and environmental protection performance of new building materials. At present, the existing glues used for building materials generally contain a certain amount of formaldehyde and benzene, which is the origin of the saying "no aldehydes, no glue". Moreover, traditional glues need to be heated to make them during production, and this Although this kind of glue produced by heating can...
