Problems solved by technology
[0004] The above types of resins are mainly composed of organic components, and their wear resistance and durability are not outstanding enough. The life of the coatings made of them is generally about several years, and the longest is no more than 15 years. The above resins have their own strengths, but they can meet There are not many resins that require wear resistance, high temperature resistance and waterproof.
Most of the coatings made of the above resins contain a large amount of volatile organic solvents, and their VOC indicators seriously exceed the requirements of national environmental protection standards. During production, transportation, storage, and construction, they cause great damage to the environment and human body. They have been engaged in coating production for a long time , the construction personnel all have different degrees of occupational diseases, and there are always potential safety hazards in the process of production, storage and transportation.

Abstract
The present invention relates to composite resin and is especially one kind of composite resin for paint and its preparation process. The composite resin contains silicate solution, organosilicone solution, organic resin and initiator. Its key parts are organic resin and inorganic silicate active molecular group and it has excellent performance after being compounded under the action of the initiator. It has excellent wear resisting, high temperature resisting, waterproofing and adhering performance. It is compounded with conventional color, stuffing and assistant to produce environment protecting paint without benzene, toluene and other organic solvent.
Description
technical field [0001] The invention relates to a composite resin, in particular to a composite resin for paint. Background technique [0002] The raw materials of coatings are mainly composed of four types of materials: resins, pigments, fillers, and additives. [0003] Coating resins, that is, adhesives, are the core components of coatings. At present, domestic better coating adhesives include polyurethanes, epoxy resins, acrylic resins, alkyd resins, chlorinated rubbers, and vinyls. , organic fluorine, and various organically modified synthetic resins. [0004] The above types of resins are mainly composed of organic components, and their wear resistance and durability are not outstanding enough. The life of the coatings made of them is generally about several years, and the longest is no more than 15 years. The above resins have their own strengths, but they can meet There are not many resins that are wear-resistant, durable, high temperature resistant, and waterproof....
