Abstract

The invention discloses a water-containing emulsion of organic silicon resin with abrasive climate protection performance, which has the characteristics of water resistance and strong adhesive force. The surface treating agent is prepared from 30-50 parts of organic silicon resin, 10-26 parts of an ethylene oxide-propylene oxide segmented copolymer, 15-20 parts of anhydride, 1-3 parts of a first chain extender, 5-10 parts of polytetrahydrofuran, 1-3 parts of an anti-freezing agent, 0.5-1 part of a defoaming agent, 2-3 parts of a neutralizing agent, 0.5-1 part of water-soluble salt, 1-2 parts of an emulsifying agent, 4-10 parts of a ring-opening catalyst and 10-20 parts of water. The surface treating agent can be used as a surface treating agent.

Description

Technical field [0001] The present invention relates to the field of silicone resin, and in particular, a water emulsion having an organic silicone resin having abrasive climate protection properties. Background technique [0002] The aqueous material refers to a material that is water-diluent and dissolves the medium in water or dispersed in water. Water-based materials, especially aqueous coatings, due to the advantages of VOC (volatile organic compound), non-toxic environmental protection, non-burning, etc., as people's environmental awareness is getting higher and higher, more and more popular. The country also pays attention to environmental issues, and the control of solvent type materials is getting strict. Therefore, the aqueous use of materials and the application in aqueous products are increasingly needed, and it is increasinglycoming a development direction in the field of material. Silicone is the main chain of Si-O-Si, and the side chain is organic. The group's poly...
