Abstract
The water paint contains granular montmorillonite in the grain size of 1-3 mm in the amount of 3-7 wt% except acrylic emulsion, and has viscosity of 80-110 KU, preferably 95-105 KU. The preparation process includes adding granular montmorillonite in the grain size of 1-3mm into acrylic emulsion through stirring at 800-1200 rpm. The water paint may be painted onto the surface of mineral wool plate and other fragile material to form coating with firm large grains.
Description
Technical field
The invention belongs to the coating composition field, specifically relate to water-based paint compositions.
Technical background
Building coating can be divided into two big class, organic coating and inorganic paints.Present organic water-borne coatings gains great popularity, and this coating is water-borne coatings, does not have or seldom have organic solvent, and therefore health harm, the environmental pollution to the people is all very little, and very convenient during use, dilute with water cleans with water.This coating and traditional low-quality water-borne coatings are different, and be water insoluble at the film that building surface is formed, resistant, anti-wiping, waterproof, good weatherability.
Building coating is also developing to functional direction in addition, wherein has sprayed surface to be the coating of star spot shape protruding point, adsorbable obnoxious flavour; But it is very little or be the filament shape that this type of technology exists the spraying protruding point, after the coating drying protruding point can shrink recessed, not full, or protruding point problem such as easily come off.Simultaneously in order to satisfy the diversified demand of people, in the technology of making dalles such as metope, furred ceiling, often various processing are carried out on the surface of these flat sheet, added the pattern of two dimension or produce concavo-convex to form various spatial moulding, as glacier, shrinkage pool or salient point etc.With the mineral wool sound absorption board is example, has added asbestos in the former sheet material, and its intensity and good toughness in the time of need forming bigger protruding point on the surface, are to adopt hot pressed mode, and the salient point that directly extrudes all size with corresponding mould on the surface of plate comes.But in order to reach environmental protection requirement, present mineral wool sound absorption board no longer adds asbestos, its material is more crisp relatively, can damage sheet material during hot pressing, thereby can only adopt the mode of spraying at present, promptly the liquid coating that mixes up is vaporificly and sprays, fall and form salient point on the plate with spray gun.But the particle that this method forms onboard is very little, can't resemble to form oarse-grained salient point the hot-press method.Along with the raising of people's living standard, not only consider its decoration function when using building coating, go back the taking environmental conservation into consideration effect.Therefore, wait in expectation very much difference in functionality and the coating of environmental-protection function is arranged of people.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of this invention is to provide a kind of have environmental-protection function, adsorbable obnoxious flavour, can on more crisp material, form large granular convex points formula coating, and the full blocky water-based bullet coating in protruding point.
Another object of the present invention is to provide a kind of method for preparing above-mentioned coating.
The inventor is by research in depth in a large number, find to adopt water-borne coatings, be equipped with polynite, can prepare environmental-protection function, adsorbable obnoxious flavour through appropriate means, can on more crisp material, form large granular convex points formula coating, and the full blocky water-based bullet coating in protruding point.
The invention provides a kind of water-based bullet coating, containing 3～7 weight % particle diameters is the montmorillonite particle of 1～3mm and the acrylic emulsions of surplus, and its viscosity is 80～110KU, preferred 95～105KU.
The invention provides a kind of water-based bullet coating, it contains 3～7 weight % particle diameters is the polynite of 1～3mm and the acrylic emulsions of surplus, and its viscosity is 80～110KU, and preferred 95～105KU is made by the method that may further comprise the steps:
The montmorillonite particle of grain diameter 1-3mm is added down in the acrylic emulsions in stirring, and adding speed stirred under 800～1200 rev/mins rotating speed 10～20 minutes so that polynite was incorporated as suitablely in the coating at 0.1～0.4 minute/kilogram.
Described polynite is conventional or known polynite.Coating of the present invention preferably contains 4～6 weight %, the more preferably polynite of 5 weight %.
Described acrylic emulsions is the conventional or known water-borne acrylic type emulsion that contains vinylformic acid and/or its derivative polymer in this area, it can be vinylformic acid and/or its derivatives class polymkeric substance that is formed different physics and chemistry by vinylformic acid and/or its derivatives monomer material copolymerization, be aided with auxiliary agent or auxiliary material, prepare according to conventional or known method.Described auxiliary agent or auxiliary material can comprise adjustment, change or improve the routine or the known substances of the various performances of coating, for example, dispersion agent, thickening material, modification auxiliary material etc., improve coating water tolerance, color developing, glossiness, anti-ly divide water, anti-ly splash, antimicrobial invasion and attack, levelling property, erosion resistance, sticking power, stability, be easy to handle and performances such as mixing.
The method of a kind of water-based bullet of preparation provided by the invention coating, comprise: the montmorillonite particle of grain diameter 1-3mm is added in the acrylic emulsions in stirring down, adding speed is so that polynite was incorporated as suitable at 0.1～0.4 minute/kilogram in the coating, under 800～1200 rev/mins rotating speed, stirred 10～20 minutes, the add-on of described polynite is advisable preferred 95～105KU so that the viscosity of gained bullet coating is 80～110K.U..
Described blended mode, equipment and condition can adopt this area conventional or known mode, equipment and condition.Described mixing step can be to carry out in any step or afterwards in the preparation process of water-borne coatings.Preferred 0.2～0.3 minute/kilogram coating of speed that adds polynite.
But bullet coating bullet of the present invention is applied to such as forming large granular convex points formula coating on the more crisp plate surface of materials such as mineral wool board.Can under the situation of extrusion plate not, form oarse-grained salient point at plate surface.The surface processing equipment of the most handy button type flat sheet, with being coated on the mineral wool sound absorption board of coating, the grain diameter that coating forms can reach 7-8mm by its brush roll.And these large granular convex points formula coatings, the protruding point is full solid, difficult drop-off.
Coating of the present invention does not have organic solvent, does not have the harm that health and environment brought of organic solvent to the people, and transportation, preservation and use are all very convenient.Also have advantages such as resistant, anti-wiping, waterproof, good weatherability.Coating of the present invention can form large granular convex points formula coating, and the protruding point is full solid, difficult drop-off, the convenience that provides for the decoration of building surface.The surperficial adsorbable obnoxious flavour that coating of the present invention applies, quite helpful to the protection environment.
