preparation example Construction

[0072] The preparation method of the jigsaw glue of the present invention is accomplished through two steps, specifically:

[0073] 1) Dissolve acrylic acid, butyl acrylate, hydroxyethyl acrylate, vinyl acetate, silane and ammonium persulfate in water, and mix them uniformly to obtain emulsified mixed monomers.

[0074] Dissolve polyvinyl alcohol in water, add an emulsifier, then heat the resulting mixture, then add the above-mentioned emulsified mixed monomers into it and mix evenly, carry out emulsion polymerization to obtain the main rubber emulsion, then add inorganic fillers, and use a 80-100 mesh filter to Filter to obtain the main ingredient;

[0075] 2) Before use, mix the main agent and curing agent obtained in step 1) evenly according to the stated ratio.

[0076] Wherein, the emulsion polymerization reaction is carried out in a stainless steel jacketed reaction kettle provided with a heat exchanger; the temperature of the emulsion polymerization reaction is 70-85° ...

Embodiment 1

[0081] Mix 100g of the main ingredient and 15g of MDI evenly, and the main ingredient is composed of the following raw materials:

Abstract

The invention relates to plate alignment adhesive for the surface plate lamination of the engineered wood flooring. The plate alignment adhesive contains main agent and curing agent, wherein the main agent consists of the following raw materials: polyvinyl alcohol, acrylic acid, butyl acrylate, hydroxyethyl acrylate, vinyl acetate, silane coupling agent, emulsifier, ammonium persulfate, deionizedwater and inorganic filler. The plate alignment adhesive of the invention has the advantages of high bonding strength, good water resistence, environmental friend, no solvent and no formaldehyde.

Description

technical field [0001] The invention relates to a jigsaw glue for laminating solid wood composite floor boards and a preparation method thereof, belonging to the technical field of woodworking adhesives. Background technique [0002] With the integrated development of the global economy and the rise of emerging industries in the market, wood processing has new and higher standards for adhesives. Ordinary "trialdehyde glue" and polyvinyl acetate latex can no longer fully meet the bonding quality. Requirements, new synthetic resin adhesives must be developed to improve the efficiency and effectiveness of wood application and bonding. [0003] In the 1870s, Japan began to pay attention to the smell of formaldehyde emitted from the dining cabinet. Since then, it has developed low-formaldehyde and non-formaldehyde adhesives, including water-based polymer-isocyanate adhesives, also known as water-based vinyl. The polyurethane-based adhesive is API (aqueous polymer-isocyanate adhe...
