Abstract
The invention discloses a suspension bleeding-proof water-based multicolor basic paint and a preparation method thereof. The basic paint is prepared from the following materials by weight percent: 25-50% of deionized water, 0.3-1.4% of hydroxyethyl cellulose, 0.1-1.5% of PH regulator, 0.2-0.55% of dispersing auxiliary, 0.1-0.3% of wetting auxiliary, 0.1-0.5% of defoaming auxiliary, 1.0-5.0% of titanium dioxide, 10-40% of filler, 15-35% of self-crosslinking elastic emulsion, 0.2-0.6% of bactericidal and mildew-proof agent, 0.5-7.0% of hollow vitrified balls and 5.0-20% of protective colloid solution. The basic paint has the following beneficial effects that by adding the hollow vitrified balls, the density of the multicolor basic paint is greatly reduced and can keep consistent with that of the protective colloid solution, namely 1.03g/cm<3>.
Description
Technical field
The present invention relates to the building coating technical field, be specifically related to anti-bleeding aqueous colorful base paint of a kind of suspension type and preparation method thereof.
Background technology
Water-soluble colorful coating is a kind of color grain that water-based base paint use color paste toning is become various different colours; and after the color grain of these different colours mixed in the water-based system each color grain can separately exist, can reach a kind of coating of colorful granite effect after the spraying.In recent years because its high-grade decorative effect and environmental-protecting performance, in the building coating industry by wide popularization and application.
In the existing production technology of water-soluble colorful coating, colorful color-mixed base paint is owing to the adding of high-gravity filler pigment, and its density all is higher than the protection sol solution.Therefore in process of production, which kind of mode don't work, conglomeration or the rear color grain sagging phenomenon of spraying all appear precipitating in colorful particle wherein, in order to address this problem, the viscosity of all taking to improve finished product coating prevents particle precipitation, but after the finished product paint viscosity improved, its storge quality was owing to the reasons such as colorful particle precipitation, the group of connecing, colour mixture are all very poor.
Summary of the invention
For the prior art above shortcomings; the invention provides the imitative bleeding aqueous colorful base paint of a kind of suspension type; the density of this base paint is substantially the same with the density of protection glue; no matter the finished product of making coats with lacquer the viscosity height; its particle all can be good at being suspended in the protection sol solution; can not precipitate conglomeration, color grain can sagging yet after the spraying.
Further, the invention provides the preparation method of the anti-bleeding aqueous colorful base paint of a kind of suspension type.
The technical solution used in the present invention is as follows:
A kind of suspension type is prevented bleeding aqueous colorful base paint, is made by the material of following weight percent:
Deionized water: 25%～50%; Natvosol: 0.3%～1.4%, PH conditioning agent: 0.1%～1.5%, dispersing auxiliary: 0.2%～0.55%; wetting aid: 0.1%～0.3%; the froth breaking auxiliary agent: 0.1%～0.5%, titanium dioxide: 1.0%～5.0%, filler: 10～40%; self-crosslinking elastic emulsion: 15%～35%; biocide mildewcide: 0.2%～0.6%, hollow glass bead: 0.5%～7.0%, protective colloid solution: 5.0%～20%.
Further, described Natvosol is Natrosol Plus.
Further, described wetting aid is the anionic wetting aid.
Further, described dispersing auxiliary is the negatively charged ion dispersing auxiliary.
Further, described filler comprises one or more the mixing in water-ground limestone, calcined kaolin, talcum powder, process white, the mica powder.
Further, described hollow glass bead is the hollow glass bead of hydrophobically modified type.
Further, described protective colloid solution is lithium magnesium silicate modified alta-mud solution, and this strength of solution is 3%～14%.
Further, made by the material of following weight percent: deionized water: 32.4%, Natrosol Plus: 0.6%, PH conditioning agent: 0.2%, negatively charged ion dispersing auxiliary: 0.4%, negatively charged ion wetting aid: 0.1%, froth breaking auxiliary agent: 0.3%, titanium dioxide: 1.5%, water-ground limestone: 15%, calcined kaolin: 15%, self-crosslinking elastic emulsion: 22.1%, biocide mildewcide: 0.4%, hollow glass bead: 2.0%, concentration is 6% protective colloid solution: 10%.
The preparation method of the anti-bleeding aqueous colorful base paint of a kind of suspension type; above-mentioned component; to be ground to fineness≤50 μ m after raw material deionized water, Natvosol, PH conditioning agent, dispersing auxiliary, wetting aid, froth breaking auxiliary agent, titanium dioxide and the filler mixing and stirring first, add again raw material self-crosslinking elastic emulsion, biocide mildewcide, hollow glass bead and protective colloid solution stirring and mix.
Compared to existing technology, the present invention has following beneficial effect:
1, the present invention has added hollow glass bead in prescription; the hollow structure that it is special; reduced the density of base paint system, made it basically identical with the protective colloid solution density, like this; after the colorful granulation and after the multi-color lacquer storage; its color grain all can be suspended in the colorful system uniformly, after the spraying, because himself density is low; on body of wall, colorful particle can sagging yet.Simultaneously, because suspension type and the bleeding resistance of colorful particle, the finished product multi-color lacquer coating storge quality of being made by the colorful base paint of this kind is greatly improved.
2, the present invention selects anionic wetting agent and negatively charged ion dispersing auxiliary, and its ionic charge is consistent with protective colloid solution, helps it to repel each other with electric charge, stops after the colorful particle granulation particle and protective colloid solution miscible, prevents colorful particle bleeding.
3, the present invention selects Natrosol Plus as thickening material, reduce the water-soluble of aqueous colorful base paint, its molecular chain launches rear special " card room " structure energy active block pigment molecule, filler molecule, water molecules, emulsion molecule, make it collaborative with the electric charge effect of repelling each other after granulation, improved the impervious look ability of colorful base paint.
