Problems solved by technology

Increasing the solid content and reducing the use of organic solvents is the best method. In recent years, technicians in the coating and related fields are keen on the research of alkyd resins, but most alkyd resins still have many problems. When When the solid content of alkyd resin is high, the viscosity of the resin is high, and when the weather is cold, it has the disadvantage of slow drying

Abstract

The invention belongs to the field of industrial paints and coatings, and in particular relates to an environment-friendly quick-drying high-solid alkyd resin and a preparation method thereof. The alkyd resin provided by the present invention is composed of the following raw materials according to mass percentage: 14%-16% of soybean oil, 14%-16% of dimer acid, 20%-25% of phthalic anhydride, and 5%-7% of pentaerythritol , 7%-9% diethylene glycol, 10%-15% isophthalic acid, 2%-5% reflux xylene, 12-30% environmentally friendly solvent. The alkyd resin is benzene-free, low-toxic, low-cost, high in solid content, belongs to environment-friendly paint, and is suitable for popularization and use in large quantities.

Description

technical field [0001] The invention belongs to the field of industrial paints and coatings, and in particular relates to an environment-friendly quick-drying high-solid alkyd resin and a preparation method thereof. Background technique [0002] Alkyd resin is an important coating resin, which is synthesized by polyhydric alcohol, polybasic acid and fatty acid through esterification and polycondensation reaction; alkyd resin is a kind of synthetic resin widely used in coatings, and it is also the most widely used synthetic resin in my country at present. One of the resins, it is cheap, easy to construct, rich in raw materials, soluble in a variety of organic solvents, and suitable for protective coatings on all wood and metal surfaces. It has good wetting and dispersibility for pigments and fillers, excellent gloss and fullness, and can be miscible with many other resins. Alkyd resin paints with different properties can be prepared through modification. [0003] With the imp...
