Multicolor finish and preparation method thereof.
Background technology
Water-in-water multicolor coating, is liquid granite coating (the artificial granite series of products of a spray mo(u)lding) again.It is
Refined by the water-base resin of liquid and wrap up jellied hydrate colour particle, and be uniformly suspended within specific water-based emulsion,
Ultimately form the copolymer of the macromolecule liquid colloidal colourful, granular size is random.Unique technique for packing makes it
Water-borne modification completely, environment-protecting asepsis, substitute increasingly rare natural granite, the energy-conserving and environment-protective meeting country require.It is given birth to
The appearance of film producing is uneven, mixes colours ten million kind, decorative pattern is changeable, and color can be overlapped mutually, good decorating effect, and big
The fidelity of reason stone can accomplish more than 95%.Along with different lattice seam meter, the theory of modernization and traditional natural style
Combination, bring up luxurious, serious decorative effect is built with relatively low cost.Compared with natural granite, cost is it
30%-40% about.Compared with natural granite or true mineral varnish, water-in-water multicolor coating, can because of the material of its lightweight
Significantly to lighten the burden to body of wall, meet developing direction.There is good ductility simultaneously again, metope fine cracks can be covered.Make
With professional water-in-water multicolor coating spray gun, once i.e. plastic, the construction time is short.Be a kind of water-based, nuisanceless, be rich in granite
Texture, the environment-friendly products of macromolecule element structure.
But because now common on the market water-in-water multicolor coating is all the method using section granulation, and true with taking out
How the empty method granulation defect such as color grain can be led to frangible, fuzzy, all preferably both therefore developed a kind of various aspects of performance
The water-in-water multicolor coating that can granulate, with vacuum filtration, granulation of again can cutting into slices becomes the technical problem being badly in need of solving in this area,
Become main research direction.

The water-in-water multicolor coating that various embodiments of the present invention provide, has excellent weather-proof, water-fast, alkaline-resisting, abrasion resistance
Can, rich color, the broken point of color grain is few, has the advantages that high fidelity.But also have that cost performance is high, adhesive force is good, paint
Film-strength is high, performance that is covering some conventional water-in-water multicolor coatings such as blind crack, easy clean anti-soil.
Water-in-water multicolor coating in the present invention, protection glue is used for forming one layer of flexible protection on base paint surface
Film, this layer of diaphragm can prevent the pigment in dispersion phase from penetrating into decentralized medium.Continuous phase then has good filming function.
Wherein protection glue is mainly mixed with rubber powder by water, and it is many that the quality of its performance is directly connected to final water-water
The practicality of color coating material, if gel diaphragm insufficient strength, the pigment in dispersion phase and the additive meeting on base paint surface
Constantly outwards oozed out by fragile diaphragm so that color on decentralized medium band, turbid phenomenon occurs it is therefore desirable to be formed
Protection glue has larger absorption property and package action, and this selection also determining concrete rubber powder species and each raw material have
The consumption of body, preferably, water takes 270-280 part, can also take 265,266,267,275,276 parts etc., Protection glue part takes 23-25
Part；Protection rubber powder takes 24-25 part, can also take 23.5,23.6,24.3,24.5 parts etc., the species of concrete rubber powder is preferably selected silicon
Sour magnesium lithium or aluminium-magnesium silicate or the two mixture, because both materials easily form glue, also meet as protection glue
Each side demand.
Various additives in base paint are essential, and its specific additive can be adjusted for wetting agent, dispersant, PH
One or more of agent, defoamer, preservative, mould inhibitor, antifreezing agent, coalescents and cellulose, each species additive
It is respectively provided with and is allowed to form homogeneous state, if dosage is very few slightly will become cotton-shaped to stir；If dosage excessively meeting again
Excessive chip is had to produce.Therefore its addition should be controlled in a rational scope.Preferred conventional additives
Total amount is 13-14 part.Antifreezing agent is preferably selected propane diols, in addition, in order to subsequently have preferable granulating effect and for point
The consideration of dephasing stability, in base paint, the preferred addition of other raw materials is：Water 150-155 part, emulsion 75-80 part is modified
Bentonite 0.3-0.5 part, modified alta-mud both can improve the viscosity of dispersion phase, can improve its mechanical strength again and color grain is steady
Qualitative.
Present invention also offers prilling process, both can be with water-in-water multicolor coating Special vacuum pumping and filtering device (by Jiangyin
Full of power and grandeur chemical machinery Co., Ltd of city produces, device name：DC type colorful example straining machine, model：DC-2)) granulate, but permissible
From traditional dicing method granulation.Using the method for vacuum filtration, can obtain specifying the color grain of size, shape is mellow and full, all
Even consistent, reduce the generation of particle it is easy to control, simple to operation.Using the method granulation of section, operating process is simple,
Color particle shape shape variation.
