Problems solved by technology

[0002] With people's increasing attention to clean production methods, environmental protection regulations, and the increasing environmental appeal of the terminal market, the glue used for impregnating wood grain paper that has lasted for many years has also been questioned more and more; conventional wood grain paper impregnation Glue has long been based on melamine / urea-formaldehyde as the main type of water-based glue (resin). In principle, it cannot eliminate pollutants such as formaldehyde. Its production and processing process is full of formaldehyde, and it is also polluted by formaldehyde in the production process of impregnated wood grain paper; Terminal furniture / flooring and other products will also slowly release formaldehyde, and the entire industrial chain is hovering on the edge of environmental protection

Abstract

The invention relates to novel aqueous polyurethane-acrylate composite impregnating resin and a preparation method thereof and aims to enable resin prepared by the method provided by the invention to simultaneously have the advantages of aqueous polyurethane and water-based acrylic acid, and become aqueous polyurethane-acrylate (PUA) composite resin. The technical scheme is that the novel aqueous polyurethane-acrylate composite impregnating resin is prepared from the following components: an acrylate monomer, dimethylolpropionic acid (DMPA) and the like; the preparation method of the novel aqueous polyurethane-acrylate composite impregnating resin comprises the following steps: firstly, preparing a polyurethane prepolymer; secondly, preparing an aqueous polyurethane-acrylate monomer mixed emulsion; thirdly, adding 20 percent of the mixed emulsion obtained by preparation in a reactor, adding remaining deionized water, improving the temperature to be 80 DEG C, and adding potassium peroxodisulfate serving as an oxidant for initiating; at the moment, paying attention to controlling temperature mutation; after clear blue light appears in the emulsion, keeping the reaction temperature unchanged, and dropwise adding remaining mixed emulsion and sodium hydrogen carbonate serving as a buffering agent.
