Abstract

The invention discloses novel alkyd resin containing titanium. A preparation method of the novel alkyd resin includes the following steps that 1, polyatomic acid anhydride, monobasic acid, polyhydric alcohol, vegetable oleic acid and antioxidant are mixed in a reaction kettle, a reaction is conducted at the temperature of 150-250 DEG C till the acid value is smaller than 15, and then the temperature is lowered to 30-100 DEG C; 2, then organic solvent and organic titanium are added and stirred to be uniform, and a reaction is conducted for 4-8 hours at the temperature of 80-120 DEG C; the organic solvent is one or more of fat hydrocarbon solvent oil, n-butyl acetate, acetic ether and acetic acid methyl ester; the weight ratio of polyatomic acid anhydride to monobasic acid to polyhydric alcohol to vegetable oleic acid to antioxidant to organic solvent to organic titanium is (130-150): (18-25): (125-145): (240-260): (1-2): (480-510): (38-46). The alkyd resin containing titanium prepared through the preparation method is high in drying speed, lustrousness and hardness, good in adhesive force and free of toxic or harmful substance.

Description

technical field [0001] The invention belongs to the technical field of synthetic resin materials, and in particular relates to a novel titanium-containing alkyd resin and a preparation method thereof. Background technique [0002] Alkyd resin is an important resin for coatings. It has rich sources of monomers, low price, many varieties, large formula changes, convenient chemical modification and good performance. Alkyd coatings also have good workability and high film fullness. , good flexibility and other characteristics, widely used in the decoration and protection of steel structures. However, it is not easy to dry and cure slowly at room temperature, and its coating film has low hardness, poor water resistance and weather resistance. In order to improve these problems of alkyd resin itself, the modification of alkyd resin has become a necessity of alkyd resin. At present, the modification of alkyd resin mainly has the following directions: [0003] (1) Styrene modified...
