Description
Technical field
The present invention relates to a kind of waterproof paint, particularly relate to a kind of Environmental-protecwaterproof waterproof paint.
Background technology
Water-proof material on market is several, and one is polyurethanes waterproof paint, and this kind of material is generally be made up as starting material of Polyurethane and coal tar.The tar gas toxicity that it volatilizees is large, and is not easy to remove, and is therefore prohibited from using in 2000 in China.The polyurethane waterproofing coating still sold replaces coal tar as raw material with pitch.But when using this coating, general employing is diluted containing the organic solvent such as toluene, dimethylbenzene, thus also containing toxic; Waterproof paint conventional is in the market two-component type waterproof paint, one of its composition is latax, in order to improve the film forming properties of coating, usually in latax, add organic solvent, thus make the content of volatile organic solvent and free formaldehyde higher, can irritating smell be produced in construction process, stimulate skin and the respiratory system of people, harm people healthy, the anti-ultraviolet property of two-component type waterproof paint is poor, and produce, transport comparatively bother; Another kind of is polymer cement-base waterproof coating, the emulsion that it is synthesized by multiple waterborne polymeric forms with the high grade cement being mixed with various additive, the flexibility of polymkeric substance (resin) and the rigidity of cement became one, and make it in impermeability with stability, show excellence.Its advantage is that easy construction, comprehensive cost are low, and the duration is short, and asepsis environment-protecting.Therefore, polyalcohol cement basis has become the leading role in waterproof paint market.
If publication number is CN103275584A, name is called the patent of invention of " a kind of polymer cement waterproof paint ", and the coating of this patent is made up of polyacrylic ester 100 ~ 120 parts, 70 ~ 88 parts, styrene-butadiene rubber(SBR), 2 ~ 9 parts, calcium carbonate, lignocellulose 3 ~ 10 parts, silica powder 0.2 ~ 2 part, cement 60 ~ 75 parts, dispersion agent 12 ~ 15 parts, defoamer 1 ~ 5 part, 10 ~ 20 parts, calcium carbonate, membrane-forming agent 1 ~ 4 part.Employ polyacrylic ester and the styrene-butadiene rubber(SBR) of larger proportion in this patent, the two can discharge toxic substance when temperature is higher, and stimulate human body skin and mucous membrane, Long Term Contact is easily carcinogenic, the health of harmful to human.
Summary of the invention
It is bad that the present invention is intended to solve the feature of environmental protection that in prior art, polyurethanes waterproof paint, polymer cement-base waterproof coating all exist, and the problem be detrimental to health, proposes a kind of new Environmental-protecwaterproof waterproof paint.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of Environmental-protecwaterproof waterproof paint, is characterized in that: comprise following raw material by weight: low-heat portland cement 70 ~ 96 parts, 0 ~ 10 part, flyash, limestone powder 0 ~ 10 part, redispersable latex powder 4 ~ 15 parts, ether of cellulose 0.3 ~ 0.5 part, water reducer 0.5 ~ 0.8 part.
The fineness of described limestone powder is 200 ~ 400 orders.
Described redispersable latex powder is the one in ethylene-vinyl acetate copolymer, vinyl acetate between to for plastic-tertiary monocarboxylic acid ethylene copolymer.
Described ether of cellulose is ethoxyl methyl cellulose ether, and viscosity is 15000 ~ 50000mPas.
Described water reducer is powdery naphthalene water reducer, and water-reducing rate is 10 ~ 30%, to improve the workability of coating.
The present invention, relative to prior art, has following beneficial effect:
(1) waterproof paint of the present invention avoids adding of organic solvent, and the feature of environmental protection is better, and has good water proof anti-seepage and anti-ultraviolet performance; Compared with general polymer cement-base waterproof coating of the prior art, the cement that the present invention adopts is low-heat portland cement, its hydration process is slow, and hydration heat is low, reduce because the distortion of water consumption and temperature difference generation in cement hydration process, and the later strength of material and overall use properties can be improved; In addition, in the present invention, select redispersable latex powder, compared with the emulsion adopted in prior art, the content of volatile organic matter in waterproof paint can be reduced by high degree, and environment-protecting asepsis, extend the working life of waterproof paint simultaneously, reduce the cost of user; Flyash in the present invention has activity, reacts with hydrolysis product of cement, and is industrial residue, can turn waste into wealth, alleviate environmental stress, reduce costs; Limestone powder in the present invention plays the effect of filling, and the ether of cellulose in formula plays thickening, resists and hang from above and water conservation, prevents aquation incomplete, affects the effect of later strength, improve product use properties; To sum up, by coordinated effect and the specific proportion design of each raw material in formula, such that waterproof paint of the present invention has environmental protection, water resistance is good, later strength is high, use properties is good and the advantage that cost is low.
(2) fineness of the limestone powder in the present invention is 200 ~ 400 orders, and the limestone powder within the scope of this fineness effectively can reduce the Young's modulus of waterproof paint, avoids waterproof paint water requirement excessive, and the problem of drying shrinkage, cracking appears in the later stage of causing.
(3) redispersable latex powder of the present invention is the one in ethylene-vinyl acetate copolymer, vinyl acetate between to for plastic-tertiary monocarboxylic acid ethylene copolymer, these two kinds of raw materials are after being dissolved in water, two-step film forming process can not discharge harmful material, and has good anti-ultraviolet property and higher thermotolerance and stability.
(4) ether of cellulose of the present invention is ethoxyl methyl cellulose ether, and viscosity is 15000 ~ 50000mPas, and this raw material is solubilized in cold weather conditions, and film forming properties is good, and still can keep good use properties at relatively high temperatures.
