Abstract

The invention relates to the field of alkyd resin, in particular to a preparation method of odor-less fast-dry alkyd resin. The odor-less fast-dry alkyd resin comprises, by weight, 9-15 parts of fattyacid, 5-12 parts of castor oil, 20-28 parts of polyhydric alcohols, 24-33 parts of organic acid, 2-5 parts of reflux solvents, 0.05-0.2 part of antioxidant additives and 23-27 parts of diluting solvents. The preparation methods includes: by a step-by-step feeding method, subjecting fatty acid, a part of organic acid and a part of polyhydric alcohols to esterification reaction, and adding in castor oil, the rest organic acid and the rest polyhydric alcohols to perform esterification reaction, so as to obtain the odor-less fast-dry alkyd resin. The alkyd resin has the advantages of fast drying,high solvent release property, less odor, high hardness, scratch resistance and the like, further has excellent flexibility without adding of other flexible resin and accordingly can improve production efficiency and have high competitiveness in application of modern furniture factories.

Description

technical field

[0001] The invention relates to the field of alkyd resins, in particular to a method for preparing odor-cleaning and quick-drying alkyd resins. Background technique

[0002] As people's awareness of environmental protection is getting stronger and the country's environmental protection policies are becoming more and more stringent, environmentally friendly wood lacquers represented by water-based wood lacquers and UV wood lacquers are getting more and more attention from the market and the industry. However, there are problems such as high requirements on equipment, materials, and cost, and the technology is not yet fully mature, product performance is uneven, and the market penetration is not high, so it cannot replace traditional solvent-based wood lacquers in large quantities.

[0003] The two-component polyurethane paint (hereinafter referred to as PU paint) in the traditional oily wood paint has become the largest type of wood paint in China due to its e...
