Method for preparing functional environmentally-friendly paint

Abstract

The invention relates to a method for preparing a functional environmentally-friendly paint. The preparation method comprises: adding 10-100 parts of glycerol, 10-100 parts of pentaerythritol, 5-80 parts of trimethylolpropane, 20-200 parts of phthalate, 3-60 parts of adipic acid, 10-80 parts of trimellitic anhydride, and 15-150 parts of maleic acid into a reactor; heating the reactor to make the substances therein react; after a complete reaction, adding in 0.03-3 parts of a defoamer; cooling the reactants, and gradually adding in 0.05-2 parts of hydrogenated castor oil and 0.05-2 parts of a polymerization inhibitor during the cooling process; adding in 8-95 parts of styrene to modify a product; and adding in 4-60 parts of triethylamine, 3-70 parts of a solvent, 15-230 parts of a pigment and a filler, 0.01-2 parts of a leveling agent, 0.5-6 parts of a catalyst, 3-7 parts of a first solid additive, 1.5-6 parts of a second solid additive, 6-9 parts of a first composite modifier, 7-11 parts of a second composite modifier, and 8-14 parts of a third composite modifier to obtain the functional environmentally-friendly paint. The functional environmentally-friendly paint prepared by the method is stable in performance, little in environmental effect, and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a preparation method of a functional environmental protection coating, in particular to a preparation method of a functional environmental protection coating. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, the concept of green decoration has attracted more and more attention. Alkyd products have irreplaceable advantages such as full paint film, bright color, convenient construction, high gloss and excellent mechanical properties. In the home improvement market where water-based coatings are popular, they still occupy a very important share. Although the traditional environmentally friendly alkyd paint has a good potential for environmental protection, in the traditional alkyd resin synthesis process, xylene solvents must be used, and metal soap driers and pigments must be used when making paint films. If the paint and pigment are not controlled, they will contai...

Problems solved by technology

Although the traditional environmentally friendly alkyd paint has a good potential for environmental protection, in the traditional alkyd resin synthesis process, xylene solvents must be used, and metal soap driers and pigments must be used when making paint films. If the paint and pigment are not controlled, they will contain heavy metal salts harmful to the human body, such as lead, chromium and other heavy metal substances, which will more or less cause negative effects on the human body and the environment. For example, the publication number is CN104046150A (2014-09 -17) The disclosed polyvinylidene fluoride modified polyvinyl chloride coating is not only harmful to the environment, but also its preparation method is quite cumbersome
