Abstract

The invention discloses a high-performance water-based resin and a preparation method thereof. The high-performance water-based resin is prepared from the following components in parts by weight: 60 to 120 parts of epoxy resin, 10 to 20 parts of flatting agent, 20 to 35 parts of neopentyl glycol, 15 to 35 parts of isophthalic acid, 10 to 22 parts of hexahydrophthalic acid, 10 to 15 parts of phthalic anhydride, 11 to 18 parts of trimellitic anhydride, 20 to 30 parts of adipic acid, 10 to 15 parts of p-methoxyphenol and 10 to 13 parts of base material wetting agent. The invention relates to an environment-friendly adhesive which is prepared from the following raw materials in parts by weight: 15-25 parts of dimethylethanolamine, 10-14 parts of a dry crosslinking enhancer, 11-16 parts of a wetting dispersant, 20-35 parts of vegetable oil fatty acid, 30-50 parts of alkyd resin, 10-15 parts of an initiator, 10-20 parts of a surfactant and 10-30 parts of a catalyst. According to the high-performance water-based resin, the hardness, the corrosion resistance, the weather resistance, the dryness and the adhesive force performance are correspondingly improved, and compared with existing water-based resin, the film drying time is shortened.

Description

technical field [0001] The invention belongs to the technical field of high-performance water-based resin, and in particular relates to a high-performance water-based resin; in particular, it also relates to a preparation method of a high-performance water-based resin. Background technique [0002] Water-based resin is a new type of resin system that uses water instead of organic solvents as the dispersion medium. Combine with water to form a solution, and after the water evaporates, a resin film material is formed. Water-based resins are not water-based resins themselves, but film materials obtained after water volatilization. Water-based resins include three categories: water-soluble polymers, super-absorbent resins and water-based coatings. Due to their unique and irreplaceable functions , with the continuous development of scientific research and production, the industrialization of products has now formed an independent industry, which belongs to the category of fine c...
