Description
Technical field the present invention relates to a kind of coating, and particularly a kind of high-performance waterproof coating material of cement based polymer, for waterproof such as kitchen, toilet, aspects, belongs to chemistry painting industry technical field.
The existing cementitious materials intensity of background technology waterproof coating material of cement based polymer is high, has again the advantages such as polymer coating film elasticity is large, and take water as solvent.There is the advantages such as easy construction, aqueous, environmental protective, strong adaptability.Since coming out, be widely used.But there is the problems such as poor water resistance, weathering resistance is poor, resistance to acids and bases is poor, tensile strength is low in this series products.Therefore, invent the antiacid waterproof paint of a kind of high-performance cement based polyalcohol necessary.
Summary of the invention the object of this invention is to provide the antiacid waterproof paint of a kind of high-performance cement based polyalcohol, and it is good that this product not only has high-weatherability, also has the advantages such as anti acid alkali performance energy, water tolerance are good, high-effective water-proof, and in construction process without adding enhancement layer.
The antiacid waterproof paint of a kind of high-performance cement based polyalcohol counts by weight percentage A, two components of B are:
A component: ACRYLIC EMULSION: 76-78%; Defoamer: 0.8-1%; Dispersion agent: 0.5-0.8%; Lignocellulose: 0.2-0.4%; Fluorine carbon emulsion: 18-20%; Polypropylene fibre: 0.1-0.3%; Sterilant: 0.05-0.15%;
B component: 325# black cement: 55-62%; 200 order quartz sand: 28-32%; 325 order coarse whiting: 8-13%; Water reducer: 0.1-0.3%.
The mixing ratio of A component and B component is: A:B=1:1.2-1.5
Principle of the present invention is based on the dehydration of elastomeric polymer emulsion, to become to have cohesiveness and successional elasticity is filmed, cement absorbs the water in the middle of emulsion and hardens, elastic polymeric coating and hardening of cement body mutually run through and be firmly bonded to high water-fast, high tenacity, a high-effective water-proof films, elastic polymer-filled is in the middle of the space of hardening of cement body, the snappiness that made hardening of cement tool, and hardening of cement body has also improved the hardness of filming in the middle of being filled in polymkeric substance.
The emulsion that the present invention uses is the acrylate copolymer without softening agent, and solids content is 54-56%, and minimum film-forming temperature is-25 ℃ of left and right.Can improve the flexibility of cement, and have good water-fast, alkaline-resisting and sticking power, and this emulsion is pure acrylic acid copolymer resins, water-proof emulsion EVA system, SBR system, the styrene/acrylic used with tradition are that resin geometric ratio has excellent weathering resistance, weather resistance.
The characteristic organic fluorine element of the fluorine carbon emulsion that the present invention uses surpasses 6%, splendid water tolerance, overlength weathering resistance, anti-contamination, not xanthochromia.Alkali resistant, Acid Rain, salt fog resistance.Paint film light, plentiful, good fluidity.
The lignocellulose length that the present invention uses is 300-400um, and density is 0.8～1.3g/cm
3.Have excellent workability, anti-current pendant performance, improves tensile strength of material, and can play good cracking resistance effect.
The polypropylene fibre that the present invention uses is reel off raw silk from cocoons production technique and surface-treated 100% polypropylene through special, and length is in 6-8mm.Can improve the bond stress with cement material, the waterproof paint ultimate elongation rate that is mixed with fiber is improved, thereby greatly improve the tensile strength of waterproof paint.In addition, this fiber can be easy to rapidly mix with coating, is monofilament state and is evenly distributed in system, forms a uniform three-dimensional netted unrest to support system.Thereby produce a kind of stiffening effect effectively, reach cracking resistance, impervious, shock resistance, freeze proof, the object that increases tensile strength.Thereby in construction process without adding the enhancement layers such as glass-fiber-fabric.
The dispersion agent that the present invention uses is low-molecular-weight polypropylene amine acid salt dispersion agent, can significantly improve concentration and the stability thereof of color stuffing dispersion pulp.
The defoamer that the present invention uses is dimethyl siloxane defoamer.Experiment showed, that this defoamer is better than the effect of mineral oil defoaming agent.
The water reducer that the present invention uses is how series high-efficiency water-reducing agent of FDN type, has the functions such as non-bleed, super plasticizing, efficient diminishing and enhancing, and strengthens the degree of compactness of filming.
The quartz sand that the present invention uses is 200 orders, and coarse whiting is 325 orders, and the label of black cement is 325#.
Production technique of the present invention is: A component: after weighing in the ratio of formula, be sequentially added into various materials under stirring at low speed, stir; B component: add dry powder blender to mix after black cement, coarse whiting are weighed according to the ratio of formula.
During use, at the construction field (site) A and B just can be carried out to roller coating in the ratio mixing and stirring of 1:1.2-1.5.
Below embodiment, be one embodiment of the present of invention.
