Description
Technical field
The present invention relates to art coatings industry, is related to a kind of " water-water " colorful environment protection multifunctional coating and preparation method thereof, is the ornament materials of a kind of environmental protection, safe, weather-proof, freedom from cracking, parian and granite decorative pattern.
Background technology
Multicolor finish can be divided into oil bag oil, Water-In-Oil, oil-in-water, 4 class of water-water, raising Water-borne modification required with people and the requirement of environmental protection, front 3 class is eliminated substantially, water-in-water multicolor coating becomes the focus of research, it is the main theoretical basis of the reform of Chinese economic structure using the theory of colloid chemistry and surface chemistry in physicochemical system as product design, there is the physical change of material and the conversion of chemical reaction in preparation process, by the water-base resin of liquid through the jellied hydrate colour particle of ion coated, and be uniformly suspended within specific water-based emulsion, ultimately form colourful, the copolymer of the random macromolecule liquid colloidal of granular size.
Water-soluble colorful coating is have U.S. John.c.zoLo to propose in late 1960s earliest.The eighties in 20th century, John.c.zoLo was improved to particle settling stability problem, but particle settling stability problem is not solved.Enter 21 century, for the research of multicolor finish still in the ascendant, Japanese Kansai Broadband Trial Network paint company, sk companies also have multicolor finish in terms of research.
China can substantially be divided into two stages with regard to the research of " water-water " multicolor finish.The nineties in 20th century is the research and development initial stage of " water-water " multicolor finish, and to 21 century at the beginning of, with the raising of domestic living environment, Domestic Environment requires the raising with ornamental demand.Domestic several research staff carry out the research of conditionity and processing performance in " water-water " bin stability, application property.With the research of domestic water-soluble colorful coating in recent years, there is problems with the research of water-water coating：Floating layer and low, the work progress complexity etc. that sinks to the bottom problem, bleeding problem, coating film gloss.
Content of the invention
It is an object of the invention to provide a kind of " water-water " colorful environment protection multifunctional coating and preparation method thereof, for existing aqueous colorful floating layer and sink to the bottom the low problem of problem, bleeding problem, coating film gloss, the preparation method of multi-functional " water-water " multicolor finish of offer one kind of the present invention.
At present, Protection glue：Prepare the protection glue solution of water-soluble colorful coating（Continuous phase）There are four kinds of systems at present.（1）Polyvinyl alcohol, starch, galactomannan take sugar/borate salt system（2）Cellulose ether/special magnesium silicate/lithium salts dispersion（3）Cellulose ether/inorganic salt system（4）Cationic galactomannan shellac varnish/anionic dispersant system or anion latex paint/cation dispersion system these four compositions two kinds of systems of the soft particle of water-water and solid particles in the market, soft particle is suitable for big decorative pattern, in spraying process, color tablets are bursted forth naturally, decorative pattern border slightly obscures, the smooth nature of paint film, but the system is not suitable for little decorative pattern, solids subsystem is suitable for little decorative pattern, decorative pattern sharpness of border, paint film have concave-convex sense, when with the system production big-pattern, granulation process is difficult to control, and whole structure is more like terrazzo rather than marble and granite.Poor adhesive force, decorative pattern are unnatural, poor water resistance, and the conversion of soft or hard particle is difficult to, fills a prescription complicated and often will adjust.The present invention forms gel using the zwitterion between organic polymer auxiliary agent and chemical commissure, and the gel is a kind of elastomer, and particle soft or hard is adjustable to be suitable for all decorative patterns.
Base paint：Film forming matter needed for base paint selects self-crosslinking elastic emulsion, without coalescents during with paint, because coalescents are mostly alcohol ethers compound, Protection glue is affected than larger, and base paint mid-early stage is added to auxiliary agent dispersant, bactericide, defoamer.Auxiliary agent kind needed for later stage has association thickener and polyurethane levelling agent, and association thickener consumption is more, and after multicolor finish is dried, the usual corner angle of color grains profile are clearly more demarcated, otherwise polyurethane levelling agent dosage is more, then particle profile is more rounded.
The technical scheme is that
It is a kind of that " " colorful environment protection multifunctional coating, its main formula include water-water：
1. base paint formulation is as follows：Water 400-500 parts, 100,000 cellulose ether 5-10 parts, dispersant 3-4 parts, defoamer 4-5 parts, bactericide 1.5-2 parts, titanium dioxide 0-5 parts, 4000 mesh calcined kaolin 80-100 parts, multifunctional assistant 2-3 parts, elastic emulsion 250-350 parts
2. Protection glue：7% Protection glue A, 5% Protection glue B
3. dispersion phase：Base paint 80-90 parts, 7% Protection glue A 20-10 parts
4. granulate：5% Protection glue B 40-50 parts, dispersion phase 50-40 parts
5. finished product paint：Fluoro-silicone emulsion 250-350 parts, coalescents 15-25 parts, water 180-200 parts, bactericide 1-2 parts, antifreezing agent 5-10 parts, suspending agent 5-8 parts, defoamer 0.3-05 parts, each colored particle 400-500 parts, flowing rheology control agent 7-8 parts.
As preferably making which that there is feature not only, to also there are good suspension and application property, a kind of " " colorful environment protection multifunctional coating, its main formula include water-water：Fill a prescription based on its weight portion as follows：Water 400-500 parts, 100,000 cellulose ether 6-8 parts, dispersant 3.5-3.8 parts, defoamer 4.5-5 parts, bactericide 1.5-2 parts, titanium dioxide 2-5 parts, 4000 mesh calcined kaolin 95-100 parts, multifunctional assistant 2.5-3 parts, elastic emulsion 300-350 parts
2. Protection glue：7% Protection glue A, 5% Protection glue B
3. dispersion phase：Base paint 85-90 parts, 7% Protection glue A 15-20 parts
4. 5% Protection glue 45-50 part, dispersion phase 50-45 parts are granulated
5. finished product paint fluoro-silicone emulsion 300-350 parts, coalescents 15-25 parts, water 180-200 parts, bactericide 1-2 parts, antifreezing agent 8-10 parts, suspending agent 6-8 parts, defoamer 0.35-0.4 parts, each colored particle 450-500 parts, flowing rheology control agent 7.5-8 parts.
Preparation technology of the present invention is as follows：
Granulation, dispersion phase：5% Protection glue=1:0.5-1 gets the raw materials ready; broken small particles can reduce the ratio of dispersion phase; stirring vane is carried to 5% Protection glue top; control speed 100-300 rev/min; then shear rate is improved to requiring particle size or dispersion phase is all added continuous phase; then start high-speed stirred, stirring leaf shape and mixing speed affect particle size.
" water-water " of the invention colorful its functional parameter of environment protection multifunctional multicolor finish：Alkali resistance >=48 hour, resistance to water >=96 hour, abrasion resistance >=2000 time cover crack ability >=0.5, acid rain resistant >=48 hour, stain resistant≤2 grade, resistance to artificial weathering aging >=1000h.
The present invention has the beneficial effect that：1. stable height is stored, gel ratio is formed using the zwitterion between organic polymer A.B auxiliary agents and chemical commissure and is greatly improved using water-soluble inorganic salt-stable；2. process is simple, dispersion phase（Adjust the base paint that individual adjuvants consumption can obtain soft particle and solid particles）Continuous phase granulation is simple；3. bleeding is prevented using organic polymer A.B duplicate protections；4., using special suspending agent and flowing auxiliary rheological agents, solve floating layer and sink to the bottom problem；5. workability get a promotion, spray area big.
