Abstract

The invention discloses a preparation method of a multipurpose environmental protection adhesive for industrial use. The invention is obtained by polymerization reaction of methanol, VAE latex, dioctyl phthalate, butyl acrylate, sodium dodecyl sulfate, plasticizer, vinyl acetate (VAC), polyvinyl alcohol, acrylic acid and OP-10. The invention has the advantages of water resistance, waterlogging tolerance, notoxicity, non-formaldehyde performance, scarce deformation under wet or hot condition and antifreeze function, thus is necessary for domestic fitments.

Description

technical field [0001] The invention relates to a preparation method of an industrial multipurpose environment-friendly adhesive. Background technique [0002] Industrial multi-purpose environmental protection adhesive is called PVAC emulsion chemical name polyvinyl acetate adhesive for short. It is widely used in printing and binding and furniture manufacturing. It is used as an adhesive for paper, wood, cloth, leather, ceramics, etc., and can also be used as phenolic resin. Modifier for adhesives such as urea-formaldehyde resin, used in the manufacture of polyvinyl acetate latex paint, etc. [0003] The traditional industrial multi-purpose environmental protection adhesive is a water-soluble adhesive, which is formed by the action of vinyl acetate (VAC) monomer in the initiator (polyvinyl alcohol, alkyl polyoxyethylene ether, starch, acetic acid, formaldehyde, water). A thermoplastic adhesive prepared by polymerization. Its disadvantages are poor water resistance and moi...
