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 an industrial multi-purpose environmental protection adhesive. Background technique [0002] Industrial multi-purpose environmentally friendly adhesive is referred to as PVAC emulsion chemical name polyvinyl acetate adhesive. It is widely used in printing and binding and furniture manufacturing. It is used as a binder for paper, wood, cloth, leather, ceramics, etc. It can also be used as phenolic resin. , Urine formaldehyde resin and other adhesive modifiers, used in the manufacture of polyvinyl acetate latex paint. [0003] The traditional industrial multi-purpose environmental protection adhesive is a water-soluble adhesive, which is composed of vinyl acetate (VAC) monomer in the initiator (polyvinyl alcohol, alkyl polyoxyethylene ether, starch, acetic acid, formaldehyde, water). A thermoplastic adhesive made by polymerization reaction. Its shortcomings are poor water resistance and moisture resistance, easy to absorb moisture in ...
