Abstract

The invention relates to an acrylic emulsion polymer and a preparation method of a water-based paint based on the polymer, the acrylic emulsion polymer comprises a polymerizable emulsifier requiring a certain structure and an acrylic emulsion synthesized by hydroxyl-terminated polydimethylsiloxane, and when the water-based paint is used, the water-based paint can be used for preparing the water-based paint. After the water-based paint composition is used, the water-based paint composition has good water soaking resistance and is a high-hardness paint. The water-based paint composition is simple in preparation method, convenient to operate, simple and environment-friendly in process and suitable for industrial production, and a paint with good water soaking resistance and high hardness can be produced.

Description

Technical field: [0001] The invention relates to an acrylic emulsion polymer and a polymer-based water-based paint preparation method, which has good hardness and water resistance, and can maintain good weather resistance at the same time. [0002] technical background: [0003] In recent years, with the continuous and rapid development of China's economy, the continuous increase of urban processes and industrialization processes, the environmental pollution has become increasingly serious, and the country has paid more and more attention to environmental protection. [0004] At present, most of the wood paints on the market are still oil-based paints, which contain a large amount of organic solvents and cause great pollution to the environment. Compared with oil-based paint, water-based wood paint uses water as a solvent, which is non-toxic and tasteless, and greatly reduces the use of organic solvents. At the moment when environmental protection has attracted much attentio...
