Abstract

The invention provides water-soluble epoxy silicone acrylic resin and a preparation method thereof. The preparation method includes following steps: 1), weighing, by weight, 63-92 parts of acrylate, 8-15 parts of acrylic acid and 5-7 parts of initiator, and well stirring to obtain mixed liquid a; 2), weighing 8-12 parts of epoxy resin, 3-5 parts of initiator and 39-62 parts of organic solvent for mixing, and well stirring and dissolving at 100-130 DEG C to obtain mixed liquid b; 3), at 100-110 DEG C, dropwise adding the mixed liquid a obtained in the step 1) at a constant speed into the mixed liquid b, holding temperature for 0.8-1.2 h after dropwise adding is finished, adding 2-4 parts of silane coupling agent, and holding temperature for 0.8-1.2 h; 4), sampling, adding a neutralizing agent water solution to detect water solubility until the sample is completely dissolved in water, and stopping reaction for cooling. When water-soluble resin is used to prepare various coatings, tap water is directly used for blending, no solvent is needed for blending, and environment protection is realized.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-soluble epoxy silicone acrylic resin and a preparation method thereof. Background technique [0002] Acrylic resin is widely used in the field of coatings because of its excellent film-forming properties, good transparency, excellent mechanical properties and environmental protection; but its molecules are mostly linear structures and lack crosslinking points, so water resistance, weather resistance and resistance The heat is poor, which affects its application range. The emergence of silicone materials provides a good solution to overcome these defects. Polyorganosiloxane has many excellent properties, such as low glass transition temperature and surface tension, special temperature resistance, weather resistance, etc. Silicone-modified acrylate is to use the excellent high and low temperature resistance and water resistance of polysiloxane to improve the ...
