Abstract

The invention provides an organosilicon epoxy acrylic acid modified waterborne alkyd resin and a coating thereof; the formula of the coating comprises the components in parts by mass: 40-50 parts of an organosilicon epoxy acrylic acid modified waterborne alkyd resin emulsion comprising the components of 45-65 parts of tung oil, castor oil or linseed oil, 25-45 parts of phthalic anhydride, trimellitic anhydride or trimellitic anhydride, 3-10 parts of xylene, 5-10 parts of epoxy ester and 5-10 parts of organosilicon ester; 3-4 parts of a pigment; 6-26 parts of a packing; 10-20 parts of deionized water; 0.05-0.5 part of a dispersant; 0.1-0.3 part of a defoaming agent; and 0.9-2.5 parts of a drier. The preparation method of the emulsion comprises the steps: heating oil, glycerol, pentaerythritol and trimethylolpropane with nitrogen protection, adding an alcoholysis catalyst, heating up, keeping a reaction until the ethanol tolerance degree reaches 2.0-5.0 ml/100 ml, and cooling; adding anhydride and xylene; adding organosilicon ester and epoxy ester, and modifying; and adding acrylate, and modifying; and cooling, and dispersing the mixture for two times. The coating has the advantages that easily-volatile organic compounds are reduced with water as a diluent.

Description

technical field [0001] This invention relates to solventborne coatings. Background technique [0002] With the enhancement of people's awareness of environmental protection and energy conservation, the application of environmentally friendly water-based coatings has become the general trend. Compared with traditional solvent-based coatings, water-based coatings greatly reduce the emission of volatile organic compounds (VOCs), and have the advantages of safety, environmental protection, low cost, and flexible construction. Water-based alkyd resin coatings use renewable vegetable oil or fatty acid as the main raw material and water as the solvent. The raw material is easy to obtain, the price is cheap, and the comprehensive performance of the paint film is excellent. It is widely used in various fields. However, waterborne alkyd resin coatings also have some defects, such as slow drying of the paint film, low hardness, poor water resistance and outdoor weather resistance, etc...
