Problems solved by technology

[0003] The current water-based alkyd amino varnish is composed of water-based alkyd resin, amino resin, pigments, additives and deionized water. When used, due to the poor UV resistance of water-based alkyd amino varnish, water-based alkyd amino varnish is vulnerable to ultraviolet rays. It becomes unsightly after irradiation, and also reduces the service life of water-based alkyd amino varnish

Abstract

The invention discloses an anti-ultraviolet water-based alkyd amino varnish and a preparation method thereof, belonging to the technical field of water-based alkyd amino varnish. The anti-ultravioletwater-based alkyd amino varnish comprises the following raw materials by mass: 25-30% of acrylic resin, 10%-15% of amino resin, 0.5 to 1.5% of nanometer titanium dioxide, 6-12% of an antirust pigment,0.1%-0.2% of a defoaming agent, 0.2 to 0.5% of a pH conditioning agent, 0.05%-0.25% of a wetting agent, 0.1 to 0.2% of a leveling agent, 8-16% of a dispersant, 4-10% of a coalescing agent, 3-10% of apreservative and 20-30% of deionized water. According to the anti-ultraviolet waterborne alkyd amino varnish and the preparation method thereof in the invention, a coating film is good in adhesive force, flexibility and weather resistance, high in gloss and excellent in decoration and protection properties; and the added nanometer titanium dioxide can well shield ultraviolet rays, has favorable dispersity and weather resistance, can be used as an ultraviolet shielding agent to prevent the invasion of ultraviolet rays, greatly enhances the aesthetic property of the water-based alkyd amino varnish in use, and greatly prolongs the service life of the water-based alkyd amino varnish.

Description

technical field [0001] The invention relates to the technical field of water-based alkyd amino varnish, in particular to an anti-ultraviolet water-based alkyd amino varnish and a preparation method thereof. Background technique [0002] Varnish, also known as varnish, is a coating composed of resin as the main film-forming substance and a solvent. Since both the paint and the coating film are transparent, it is also called transparent paint. Apply on the surface of the object, and form a smooth film after drying, showing the original texture of the object surface. Varnish can be used for coating furniture, floors, doors and windows, and automobiles. Pigments can also be added to make enamels, or dyes can be added to make colored varnishes. It is also used to make enamel paint and impregnate electrical appliances, and it can also be used to fix sketches, gouaches, etc., which has a certain anti-oxidation effect and can prolong the storage time of drawings. [0003] The cu...
