Abstract
The present invention relates to wall paint, particularly to a formula and a production method of low-cost enamel-like paint for internal walls and external walls, and the low-cost enamel-like paint has the advantages of high hardness, high smoothness and strong adhesive force. The formula of the present invention comprises: 1.0% to 5.0% of polyvinyl alcohol, 1.0% to 1.5% of fluorescent whitening agent, 0.25% to 0.28% of thickening agent, 1.0% to 1.2% of french blue, 10% to 12% of light calcium carbonate, 1% to 2% of urea, 50% to 55% of ground limestone and water as the rest. After the present invention forms films, wall surfaces have the advantages of high hardness of 6H, good smoothness like porcelain, washing resistance and strong adhesive force; the wall surfaces also has the characteristics of no wrinkling, no discoloration, no powder shedding, resistance to acid and alkali corrosion, etc. under the conditions of wind, rain, solarization, etc. Moreover, the present invention has the advantages of convenient construction and low cost, and can be used for both internal walls and external walls to achieve satisfied decorative effects.
Description
Technical field
The present invention relates to a kind of coating for wall surface, especially relate to a kind of hardness height, highly polished, the prescription of the low-cost internal-external wall porcelain-imitated coating that sticking power is high and production method.
Background technology
The architectural decoration wallcovering is a lot of in the market, and common coating has emulsion paint, and it is made up of latax, pigment, filler and a little auxiliary, is applicable to wide variety of substrates, has nontoxic pollution-free, characteristics such as easy construction; Again just like porcelain-imitated coating 888, steely with its hardness, flat side down, brilliance such as porcelain, acid-fast alkali-proof and have high share of market, but these coating ubiquity hardness are low, easily stay cut, moisture-sensitive shedding and the loss of gloss that arrives is eclipsed, again because curing speed is fast, cause constructional difficulties, therefore have a strong impact on coatingsurface quality and marketing.
Patent retrieval finds that the someone has applied for that name is called the patent (number of patent application 97106697.3) of ' novel wall surface toughened paint ', and it is main raw material that its disclosed formulation for coating material adopts calcium hydroxide and water-ground limestone, utilize calcium hydroxide in air slowly with CO
2Reaction generates lime carbonate, and these newly-generated lime carbonate are main filmogens, and it is excellent to have water resistance, the characteristics of hardness height, but a fly in the ointment is that it is bigger to the dependency of environmental quality, at suspended substance and CO
2In the big environment of content difference, cause tangible construction quality difference easily, be difficult to really give play to the high-performance of product.
Summary of the invention
The present invention mainly be solve existing in prior technology hardness low, easily stay the technical problem of cut, moisture-sensitive etc.
The present invention has also solved technical problems such as the easily eclipsed decolouring that exists in the prior art, easy shedding.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the prescription of low-cost internal-external wall porcelain-imitated coating is: polyvinyl alcohol 1.0%～5.0%, white dyes 1.0%～1.5%, thickening material 0.25%～0.28%, ultramarine 1.0%～1.2%, light calcium carbonate 10%～12%, urea 1%～2%, dry powder (water-ground limestone) 50%～55%, all the other are water.It is main raw material that the present invention adopts water-ground limestone and light calcium carbonate, by the size of control solid particulate, directly reduces in the coating film process dependency factor to environment.
Each composition weight proportion optimization scheme of the present invention is: polyvinyl alcohol 2.0%～4.0%, white dyes 1.2%～1.4%, thick dose 0.26%～0.28%, ultramarine 1.0%～1.2%, light calcium carbonate 10%～12%, urea 1%～2%, dry powder (water-ground limestone) 48%～52%, all the other are water.
White dyes kind commonly used in the coating material production is a lot, consider cost variance and add the compatibility of auxiliary agent with other, the present invention has adopted 2, the two benzoxazoles of 2-(4, the 4-diphenylethyllene), stable strong because of it, the acid and alkali-resistance degree is PH2～6, and consumption is few, and with ethylene glycol, silicon dioxide microparticle synergy is arranged, heat-resisting fast light, can overcome problems such as easy loss of gloss turns pale in the currently available products, dry linting.
The present invention can also add tributyl phosphate as defoamer, is intended to eliminate the bubble that produces in whipping process, make the coating film forming after, face is more smooth, hardness is higher, can overcome easily to stay problems such as cut, dry linting in the currently available products.
It is fast to the present invention is directed in the conventional art existing curing speed, cause problems such as construction is inconvenient, construction quality difference is big easily, can adopt silicon dioxide microparticle as thickening material in above-mentioned prescription, the mixture that can add a little auxiliary when needing is to improve its performance.Because of silica particle surface silanol group and other components change by hydrogen bond action generation three-dimensional structure, medium is surrounded, under mechanical force, (stir, brush), three-dimensional structure is emanated, remove the external force effect, system just remains static, silanol group passes through hydrogen bond action with other components once more, the generation three-dimensional structure changes, and causes the thixotropy thickening, uses silicon dioxide microparticle as thickening material, curing speed is even, moisture effect is obvious, controls construction quality easily, can overcome easily to stay problems such as cut, dry linting in the prior art.
Also can add isothiazolinone in the component of the present invention as mould inhibitor, its weight proportion is 1.0%～1.5%.Described isothiazolinone is a mixture, (The mixture of 5-chloro-2-methl-4-isothiazoline-3-one and 2-methl-4-isothiazoline-3-one), it is aqueous formulation, active matter content 〉=30%, isothiazolinone and 2,2-(4, the 4-diphenylethyllene) after two benzoxazoles, ultramarine mix, can improve paint adhesion and opacifying power, the yellow coloured light function of the elimination of ultramarine there is booster action, and refracting power is strengthened, also can add a spot of ethylene glycol when needing and make the coating mixing more even more smooth.
The manufacture craft of low-cost internal-external wall porcelain-imitated coating is: quantitative water is injected stirring tank, order adds polyvinyl alcohol, 2 in whipping process, 2-(4, the 4-diphenylethyllene) two benzoxazoles, urea, insulated and stirred be heated to 60～70 ℃ under normal pressure after is no less than 0.5～1 hour, treats that material is all after the dissolving, stop insulation, drop into ultramarine (Na in order
