Abstract

The invention discloses long-chain monomer modified polyacrylic ester emulsion, which is prepared from the following ingredients in percentage by mass: 1.0 to 3.0 percent of anionic surfactants, 0.3 to 0.9 percent of nonionic surfactants, 10 to 20 percent of acrylate monomers, 10 to 20 percent of methacrylate monomers, 0.3 to 3.0 percent of modified monomers, 0.06 to 0.24 percent of initiators andthe balance of water. The modified monomers are long-chain polyacrylic ester with the side chain carbon atom number being greater than 10. The long-chain monomer modified polyacrylic ester emulsion has the advantages that the particle diameter of the latex particles is small; the application field of the polyacrylic ester emulsion is expanded. The invention also discloses a preparation method ofthe long-chain monomer modified polyacrylic ester emulsion. The semi-continuous seed emulsion polymerization is performed; the operation is simple. The invention also discloses application of the long-chain monomer modified polyacrylic ester emulsion in paint preparation.

Description

technical field [0001] The invention relates to the field of emulsions, in particular to a long-chain monomer-modified polyacrylate emulsion and a preparation method and application thereof. Background technique [0002] Fatty alcohol polyoxyethylene ether anionic surfactants have lower irritation than other anionic surfactants, excellent resistance to hard water and good biodegradability, and can be widely used in biology, medicine, leather and papermaking, etc. In the industry, it is a green and environmentally friendly emulsifier, which meets the current requirements for energy saving and environmental protection. [0003] Long-chain acrylate is a kind of alkyl acrylate with very long side chain (the number of carbon atoms in the side chain is greater than 10). It is a monomer substance with a comb-like structure and has a very low glass transition temperature (Tg ) and a longer hydrophobic carbon chain, as an oil-soluble monomer, it has good hydrophobicity. In addition...
