Abstract
An elastic water-proofing material for cement is prepared from cross-linked polyacrylic acid emulsion (70-100 portions), ethylene-vinyl acetate copolymer emulsion (1-30), polyvinyl alcohol as modifier for stabilizing emulsion (5-10), ethanediol (1-5), phthalic acid type plasticizer (1-5), organosilicon defoaming agent (0.1-5), white cement (70-100) and inorganic filler (20-40). Its advantages are excellent water-proofing performance, high elasticity and low-temp toughness, and simple preparing process.
Description
The present invention relates to a kind of architectural waterproof material, particularly a kind of water-proof elastic cement material and manufacture method thereof.
Existing water-proof material has multiple, for example: the pitch class, the constructing operation complexity, and resistance to cleavage is bad, and unit elongation is little, and tensile strength is lower; Emulsificated asphalt water-proof painting material, its waterproof effect is poor, and weather resistance is poor; Polyurethanes, it is ageing-resistant indifferent, and is toxic, contaminate environment, and can not on moist basal plane, use.
The purpose of this invention is to provide a kind of water-proof elastic cement material and manufacture method thereof, this material not only water resistance is good, be painted on metope or the roofing after the film forming, very fine and close, and good springiness, also can keep snappiness at low temperatures, can prevent because the caused surface layer be full of cracks of basic crack, performance is good, and technology is easy among the present invention, and raw material is easy to get.
For achieving the above object, the present invention takes following design: this water-proof elastic cement material includes machine component and inorganic component, and described organic component comprises: cross-linking type polyacrylic acid emulsion 70-100 part; Ethene one vinyl acetate copolymer emulsion 1-30 part; Polyvinyl alcohol emulsion-stabilizing properties-correcting agent 5-10 part; Ethylene glycol 1-5 part; O-phthalic acids softening agent 1-5 part, silicone antifoam agent 0.1-5 part; Described inorganic component comprises: white cement 70-100 part; Mineral filler 20-40 part; The weight ratio of above-mentioned organic component and inorganic component is 1: 0.8-2.
A kind of manufacturing water-proof elastic cement material method may further comprise the steps:
(1) cross-linking type polyacrylic acid emulsion, ethene one vinyl acetate copolymer emulsion and polyethylene acids emulsion-stabilizing properties-correcting agent are placed in the dispersion machine stirs;
(2) in (1), add ethylene glycol and polyvinyl alcohol stable emulsifying properties-correcting agent, stir, obtain liquid;
(3) with white cement, mineral filler is put into stirrer and is stirred, and obtains powder;
(4) with (3), (4) two kinds of mixing of materials, its weight ratio is 1: between the 0.8-2.
Among the present invention, adopt cross-linking type polyacrylic acid emulsion, its formation be coated with the film elasticity height, snappiness is good, water tolerance, excellent in te pins of durability, the water resistance of ethane-acetic acid ethyenyl ester copolymer emulsion is good, the cohesive strength height, and price is lower, after emulsion-stabilizing properties-correcting agent adds, two kinds of emulsion blend are steadily in the long term stored, and the adding of other auxiliary agents can improve technological operation performance and some other properties of coating.
White cement in the powder can be one or more in 425,475,525 labels, mineral filler is one or more in granularity 200-400 purpose water-ground limestone, light calcium carbonate, grey calcium powder, talcum powder, the silica powder, above material is put into stirrer stir, obtain powder.
When needs have been made color with water-proof material, can add pigment, can be added in the liquid earlier as titanium dioxide, ferric oxide, chromic oxide and phthalocyanine serial pigment and mix, mix with powder again, also can add mixing in the powder earlier, again with liquid mixing.
The emulsion-stabilizing properties-correcting agent that is added among the present invention is polyvinyl alcohol, and softening agent has dibutyl phthalate, phthalates such as dioctyl phthalate (DOP).
The invention will be further described below in conjunction with embodiment:
Embodiment 1:
70kg cross-linking type polyacrylic acid emulsion and 30kg ethene one vinyl acetate copolymerization emulsion are mixed with emulsion-stabilizing properties-correcting agent polyvinyl alcohol 10kg, stir, add 5kg ethylene glycol, dibutyl phthalate 15kg subsequently, silicone antifoam agent 0.1kg.475# white cement 100kg and mineral filler water-ground limestone 20kg are mixed, with 1: 1 remix of above-mentioned two kinds of batch mixings, obtain product subsequently.
Embodiment 2
Operation steps is with embodiment 1, be not both consumption difference into various components, wherein cross-linking type polyacrylic acid emulsion 100kg, ethene one vinyl acetate copolymerization emulsion 10kg, acid polyethylene 5kg, ethylene glycol 3kg, dibutyl phthalate 2kg, silicone antifoam agent 1kg.475# cement 70kg, water-ground limestone 20kg.In powder, add pigment 10kg in addition.
Embodiment 3
Operation steps is with embodiment 1, institute's difference is the consumption difference of each component, and softening agent changes dioctyl phthalate (DOP) into, the consumption of each component is as follows: cross-linking type polypropylene emulsion 80kg, ethene one vinyl acetate copolymerization emulsion 10kg, polyvinyl alcohol 5kg, ethylene glycol 1kg, dioctyl phthalate (DOP) 4kg, silicone antifoam agent 3kg.475# white cement 140kg in the powder, mineral filler 50kg, pigment 10kg mixes above-mentioned raw materials mixed, (powder in the present embodiment: liquid material (weight ratio)=2: 1).
The said products is through the test of Beijing's building materials quality supervision measuring station, and technical target of the product is as follows: tensile strength: standard-required 〉=2.0MPa measured value＞2.5MPa elongation at break: standard-required 〉=150% measured value is that (its low temperature flexibility can for 461% low temperature flexibility standard-required-10 a ℃ flawless actual measurement conformance with standard
Remain on-25 ℃).Watertightness standard-required 〉=0.3Mpa 30min is waterproof.Reach requirement.
Advantage of the present invention: waterproof material provided by the invention has good water resistance, and good springiness is low Can keep pliable and tough property under the temperature, can prevent that manufacturing process is easy, and is former because the surface layer that basic crack causes chaps Material is easy to get.
