Abstract

The invention discloses a self-dry water-soluble acrylic organic silicon resin and a preparation method thereof and an application. The self-dry water-soluble acrylic organic silicon resin comprises, by weight, 20-30 parts of methyl methacrylate, 35-45 parts of butyl acrylate, 5-10 parts of ethyl hexyl acrylate, 3-7 parts of hydroxypropyl acrylate, 6-10 parts of methacrylic acid, 2-5 parts of acrylic acid, 5-40 parts of silicone oil, 1-4 parts of silanoxide, 5-7 parts of benzoyl peroxide, 4-7 parts of isopropyl alcohol, 25-35 parts of propylene glycol monomethyl ether, 10-20 parts of ether solvents and 7-9 parts of neutralizers. The self-dry water-soluble acrylic organic silicon resin reaches water solubility by adjusting monomers and improving processes, the organic silicon resin and tap water can be infinitely mixed and dissolved, the organic silicon resin has the advantages of high brightness and hardness, impact resistance, bending resistance, boiling resistance, salt-fog resistance and the like, the brightness of the resin is larger than 90, the hardness of the resin is larger than 5H, the use cost of the resin is reduced by 60% as compared with oil paint, and the resin is safe and environmentally friendly and saves energy.

Description

technical field [0001] The invention relates to the fields of polymer synthesis and coatings, and mainly relates to a self-drying water-soluble acrylic silicone resin, a preparation method and application thereof. Background technique [0002] Based on factors such as safety, health and environmental protection, water-based coatings have gradually become mainstream products in the market. The current water-based epoxy resins only have emulsions, and most of them have the following disadvantages: 1. The proportion of water added to the emulsion is not high, and there is no cost advantage; The current water-based epoxy resin only has emulsion, and most of them have the following disadvantages: 1. The proportion of water added to the emulsion is not high, and there is no cost advantage; 2. It is easy to break the emulsion and unstable in storage; 3. The brightness of the emulsion in application performance , hardness, adhesion and other technical indicators are difficult to ac...
