Abstract

The invention relates to a polyacrylate composite emulsion modified by halloysite nanotubes and a preparation method and application thereof. The halloysite nanotube-modified polyacrylate composite emulsion of the present invention has a formula comprising the following raw material components in parts by weight: 15 to 45 parts of water, nucleus layer halloysite nanotube / acrylate monomer dispersion 30-86.2 parts, shell pre-emulsified monomer 15-42.4 parts, emulsifier 0.2-4 parts, initiator 0.15-1.2 parts, adipic acid dihydrazide 0.5-1.8 parts. The halloysite nanotube can partly replace the emulsifier in the preparation process of the composite emulsion, reduce the consumption of the emulsifier, and significantly improve the mechanical properties, water resistance and chemical resistance stability of the emulsion coating. The water-based wood paint obtained by the invention has high hardness, smooth and plump coating film, water resistance, boiling water resistance, no back sticking and strong chemical resistance, and has good application value and market prospect.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a halloysite nanotube-modified polyacrylate composite emulsion and a preparation method and application thereof. Background technique [0002] Water-based acrylate has the characteristics of rich raw material sources, relatively low cost, and good environmental protection, especially the weather resistance, mechanical strength, and gloss of its coating film. , papermaking, automobiles and other fields have a wide range of applications. However, the water resistance, chemical corrosion resistance, heat resistance and other aspects of ordinary water-based acrylate are still insufficient, so it is necessary to modify it to obtain high-performance water-based acrylate resin and expand its application range and fields. [0003] At present, the modification of acrylate emulsion mainly includes the following aspects: [0004] 1) Using advanced emulsion polymerization technology and p...
