Abstract
The invention relates to the field of paint making and especially relates to aqueous eco-friendly aluminum powder metal paint and its preparation method and formula. The aqueous eco-friendly aluminum powder metal paint comprises 50-70 parts of water-soluble acrylic resin with a mass fraction of 55%, 3-6 parts of amino resin, 8-12 parts of aqueous aluminum paste, 2-7 parts of a metal orientation agent, 0.5-1 part of an aqueous disperser, 0.1-0.3 parts of an aqueous antifoaming agent, 0.1-0.3 parts of a wetting agent, 0.1-0.8 parts of an amine neutralizer and the balance deionized water. The preparation method utilizes water as a diluent and is free of an organic solvent. The aqueous eco-friendly aluminum powder metal paint film has performances exceeding those of solvent-based paint so that use of the organic solvent in a paint industry is reduced. The aqueous eco-friendly aluminum powder metal paint prevents shrinkage cavity and pin hole, has good leveling effects, effectively prevents sagging and improves aluminum powder arrangement. Aluminum powder arrangement is tidy. The aqueous eco-friendly aluminum powder metal paint film has glossiness of 95% or more at an incidence angle of 60 degrees.
Description
Technical field
The present invention relates to paint class and make field, refer to a kind of aqueous, environmental protective silver powder metallic paint and preparation method thereof especially.
Background technology
The application of industrial coating is main still based on solvent based coating in the world at present, but along with various countries' improving constantly environmental consciousness, more and more higher requirement be it is also proposed to the use of organic solvent, in order to reduce the pollution of organic solvent to environment, the environmental protection feature of water-borne coatings seems particularly outstanding, the industrial country of each advanced person has been listed in the developing direction of industrial coating from now on, and positive developing.
Aqueous, environmental protective silver powder metallic paint is due to large (the surface tension 72mN/m of water of surface tension of water, surface of organic solvent tension force is most between 20-30mN/m), therefore the surface tension of general aqueous, environmental protective silver powder metallic paint is also larger, lower column defects and film defect is easily produced: flattening property is bad, easily produces shrinkage cavity, pin-hole phenomena during application; Easy sagging during general water-miscible paint construction, the easy sedimentation of aluminium powder, after coat bake drying, silver powder arranges uneven phenomenon; General water-miscible paint coating film gloss is relatively low, under prior art condition, common water borne environmental protection silver powder metallic paint coating film gloss when 60 ° of input angles generally all below 80 °.
Summary of the invention
The present invention can solve the problem.
The present invention is achieved through the following technical solutions.
A kind of aqueous, environmental protective silver powder metallic paint and preparation method thereof, it is characterized in that, in the formula of this aqueous, environmental protective silver powder metallic paint, the weight ratio of its component and component is: water soluble acrylic resin's (massfraction 55%): 50-70 parts, 3-6 parts, aminoresin (terpolycyantoamino-formaldehyde resin), water aluminum-silver slurry: 8-12 parts, metal directing agent: 2-7 parts, aqueous dispersant: 0.5-1 part, water-based defoamer: 0.1-0.3 part, wetting agent: 0.1-0.3 part, amine neutralizing agent: 0.1-0.8 part, deionized water: surplus; Its preparation method: 55% water soluble acrylic resin, aminoresin (terpolycyantoamino-formaldehyde resin), metal directing agent, aqueous dispersant, water-based defoamer, wetting agent, deionized water are put in high speed dispersor according to the above ratio, stir with rotating speed 800-1200rpm, add amine neutralizing agent appropriate in aforementioned proportion while stirring, until the metal directing agent in mixed solution dissolves completely, be 7.5-8 with amine neutralizing agent adjustment pH value.Add water aluminum-silver slurry in proportion again, stirring at low speed evenly.
Described water soluble acrylic resin, applied for by our company, invent artificial Bai Mingguo, application number is: 201310522749, name is called: a kind of compound method of acrylic anodic electrocoating paint, the each composition component of formula and the weight ratio that disclose a kind of acrylic resin are: vinylformic acid 48-50 part, Hydroxyethyl acrylate 67-73 part, hydroxyethyl methylacrylate 30 parts, methyl methacrylate 77-110 part, butyl acrylate 30-37 part, Isooctyl acrylate monomer 0-15 part, vinylbenzene 30 parts, butyl methacrylate 0-15 part, Diisopropyl azodicarboxylate 0-6 part, dicumyl peroxide 0-9 part.
