Abstract

The invention relates to a water-based resin for waterproof oil paint and a preparation method thereof. The water-based resin of the present invention is made of water, alkylphenol polyoxyethylene ether, sodium lauryl sulfate, polyacrylamide, styrene, butyl acrylate, methyl methacrylate, acrylic acid, ammonium persulfate, and ammonia solution . The preparation method of the resin is as follows: adding alkylphenol polyoxyethylene ether, sodium lauryl sulfate, polyacrylamide, ammonium persulfate and water in sequence to the reaction vessel, stirring and dissolving, and then adding styrene and butyl acrylate in sequence Ester, methyl methacrylate and acrylic acid are synthesized after being stirred and emulsified for 20-40 minutes. The emulsion back-drop method is adopted in the synthesis process. After the reaction is completed, ammonia water is added to adjust the pH value to obtain the water-based resin. When the resin is used in oil paints, oil paints with good water resistance and scrub resistance can be obtained. Because the chemical heat energy generated by the reaction is fully utilized, it belongs to the energy-saving and environment-friendly oil paint waterproof resin.

Description

technical field [0001] The invention relates to the field of painting materials, in particular to a water-based resin for waterproof oil paint and its preparation method and application. Background technique [0002] The waterproof ability of the oil paint itself mainly depends on the natural resin or synthetic resin used to process the oil paint. However, due to production technology, the water-based resins used in oil paints often have poor waterproof performance, which restricts the waterproof performance of outdoor oil paintings. [0003] For oil paintings, especially large-scale outdoor oil paintings, due to wind, sun, rain, outdoor oil paintings often need to be waterproofed after the completion of the production. repair. Contents of the invention [0004] One of the purposes of the present invention is to synthesize a water-based resin for waterproof oil paints. The specific technical scheme is as follows: [0005] A water-based resin for waterproof oil paint, s...
