Abstract

The invention provides a KT sheet gum and a preparation method thereof. The KT sheet gum is prepared from the following raw materials by weight percentage: 25 percent of vinyl acetate, 22 percent of butyl acrylate, 4.25 percent of methyl methacrylate, 1.178 percent of acrylic acid, 2 percent of N-hydroxymethyl acrylamide, 1.25 percent of polyvinyl alcohol 17-88, 0.95 percent of sodium dodecylbenzene sulfonate, 0.525 percent of non-ionic emulsifier OP-10 (nonylphenol polyoxyethylene ether), 0.125 percent of disodium hydrogen phosphate dodecahydrate, 0.2 percent of ammonium peroxydisulfate, 1.78 percent of potassium hydroxide, 0.1-0.2 percent of pH regulator, and 40.542-40.642 percent of distilled water. The KT sheet gum has the advantages of good initial viscosity, high cohesional strength, good water resistance, good aging resistant performance and neutral pH value, has no influence on a KT sheet, namely a PS foam material, and can perform cold gluing at normal temperature, the time for pasting composite curing is short, and the using process is convenient; besides, the KT sheet gum has no organic solvent, and the product contains no formaldehyde.

Description

technical field [0001] The invention provides a KT (polystyrene foamed board compounded with paper) board glue and a preparation method thereof, belonging to the technical field of adhesives. Background technique [0002] At present, there is a shortage of various natural resources in the world, and there is a serious shortage of various wood resources used in home decoration in the market. That is, the application of various medium-density boards and various plywood materials in the market is more than that of trialdehyde glue. The living environment has brought serious pollution and harm. With the advancement of science and technology and the development of the market, many new materials have appeared in the entire building materials market. Among them, there are boards made of polystyrene foam and paper, commonly known as KT boards, which are mainly used in bulletin boards, office boards, and exhibitions. Layout, family ceiling panels, etc., are new soft materials in the...
