Abstract

The invention provides a nano polyacrylate emulsion for a water-based wood coating and a method for preparing the same. In the method, a plurality of functional monomers are used in the design of a core-shell structure and a molecular branch chain interpenetrating network of the emulsion particles; the aim of the invention can be achieved by the polymerization technology under a condition of a reaction type emulsifier, simultaneously beta-cyclohexyl-epoxy-ethyl-ethoxy silane is used for making the coating film crosslinked in a drying process, the mechanical property of the coating prepared bythe method is greatly improved compared with the coating of the water-based polyacrylate emulsion which does not use the beta-cyclohexyl-epoxy-ethyl-ethoxy silane, the shock resistance of the coatingis over 45kg.cm, the hardness of the coating reaches H or above class, and the waterproof property of the coating reaches 240 hours.

Description

technical field [0001] The invention relates to a nano polyacrylate emulsion for water-based wood paint. Background technique [0002] Self-crosslinking water-based polyacrylate emulsion at room temperature is a composition used for coatings and adhesives. The performance and use of the water-based polyacrylate emulsion vary with the monomers, additives and synthesis processes used. Invention Patent Publication No. CN 1438253A "High Solid Content Acrylate Microemulsion for Woodenware" and other patents and documents, the disclosed technology does not use each monomer for molecular design and synthesis process design. Therefore, the crosslinking density is not high and affects mechanical properties. Contents of the invention [0003] The purpose of the present invention is to provide a kind of nanometer polyacrylate emulsion and preparation method thereof for waterborne wood lacquer, to overcome the above-mentioned defect that prior art exists. [0004] Described polyacry...
