Problems solved by technology

Although water-based alkyd resin has many excellent properties, it also has disadvantages. Its molecular structure contains more ester groups, resulting in unsatisfactory hardness of the produced coating film, and poor weather resistance, corrosion resistance and water resistance. , in order to overcome the shortcomings of alkyd resin and expand its application range, it needs to be modified

Abstract

The invention discloses a PIA (meta-phthalic acid) / nanometer titania modified alkyd resin and a preparation method thereof. The PIA / nanometer titania modified alkyd resin comprises the following raw materials: acrylic acid, methylacrylic acid, methyl methacrylate, vinyltriethoxysilane, nanometer titania, epoxy resin, castor oil, trimethylolpropane, 2,2,4-trimethyl-1,3-pentanediol, tetrachlorophthalic anhydride, PIA waste, trimellitic anhydride, triethylamine, ethyl eneglycol monobutyl ether, propylene glycol mono-n-butyl ether, lauric acid, catalytic auxiliary, benzoyl peroxide, dimethylbenzene and water. The PIA / nanometer titania modified alkyd resin provided by the invention is good in water resistance, high in hardness and excellent in comprehensive performance; the PIA waste is used, so that the cost is saved.

Description

technical field [0001] The invention relates to the technical field of alkyd resins, in particular to a PIA / nano titanium dioxide modified alkyd resin and a preparation method thereof. Background technique [0002] Alkyd resin is the most widely used synthetic resin in the paint industry. It has the advantages of low price, simple construction, easy access to raw materials, low acid value, good solubility of various organic solvents, and good performance on pigments and fillers. Excellent wetting and dispersibility, and after curing, it is glossy and tough, has strong adhesion, and has good wear resistance, weather resistance and insulation, etc. It has been used in many fields. [0003] Isophthalic acid (1,3-phthalic acid, English abbreviation IPA, high-purity product called PIA) is a white crystalline solid with strong heat resistance, water resistance and chemical resistance, easy to deflagrate, It can be sublimated and is mainly used in the production of unsaturated pol...
