Abstract
The present invention discloses a waterproof coating material of macromolecule emulsion. Macromolecule emulsion, a dispersant, a plasticiser, a defoamer, a film forming auxiliary agent and reinforcing fillers are used as raw materials; the raw materials are orderly added in a high-speed dispersion machine for uniform dispersal; then, a colloid mill is used for milling the raw materials into particles with a diameter smaller than 20 mu m for manufacturing the waterproof coating material of macromolecule emulsion. The present invention has the advantages of stable chemical performance, strong adaptability, strong weatherability, high temperature resistance, low temperature resistance, acid base resistance, high adhesive strength, safety, environmental protection, low cost and the like, and is widely applied to the engineering of the water prevention of new roof waterproof layers, old roof waterproof layers, bathroom wall surfaces and the ground, the manufacture of the field surfaces of tennis balls, the gap filling of buildings, etc. The waterproof coating material is worth popularizing and applying.
Description
Technical field
The present invention relates to a kind of construction waterproof coating, particularly relating to a kind of is the building water-proof paint of base-material with the polymer copolymerization emulsions.
Background technology
Construction waterproof coating mainly is divided into response type, solvent-borne type and emulsion-type at present.The response type waterproof paint is generally two components, forms water-proof coating by film forming matter reaction film-forming, mainly contains polyurethane series, epoxy resin waterproof paint, and such product performance are good, but price is higher, applies to be restricted.Solvent based coating is by the volatilization of organic solvent, and macromolecule resin forms waterproof coating such as chlorinatedpolyethylene, chloroprene rubber etc., because of its organic solvent volatilization contaminate environment causes cost higher.Be the coating of polyacrylic ester and copolymer emulsion thereof or other emulsion blending preferably in the emulsion-type waterproof paint, have advantages such as the resource of saving, non-environmental-pollution because of it and develop rapidly.And the emulsion-type waterproof paint is different because of emulsion varieties and characteristics, filler, auxiliary agent kind difference and prescription thereof, the production technique difference product performance used, the better performances that has, but price is higher, the low but poor-performing of the price that has.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned shortcoming, provides that a kind of performance is good, price is low, the single-component high molecular emulsion waterproof paint of safety and environmental protection.
For achieving the above object, high molecular emulsion waterproof paint of the present invention is made by macromolecule emulsion, dispersion agent, softening agent, defoamer, film coalescence aid, reinforced filling, and the weight proportion of each component is (consumption is a weight part):
Polyacrylate dispersion and polyethylene-vinyl acetate emulsion 35-75
Dispersion agent 0.2-1 softening agent 2-5 defoamer 0.2-1
Film coalescence aid 2-4 reinforced filling 30-50.
Polyacrylate dispersion/polyethylene-vinyl acetate emulsion=43: 12-35: 30, because of its molecular structure contains a large amount of polar groups, have affinity with base material, good cementability can be provided, and have good elasticity and toughness behind the crosslinking curing.
Above-mentioned high molecular emulsion waterproof paint is characterized in that: described dispersion agent is anion-type water-thinned dispersion agent, uses dispersion agent, can reduce mutual adsorptive power between inorganic filler particle, it more is suitable for is dispersed in the polymer emulsion.
Above-mentioned high molecular emulsion waterproof paint is characterized in that: described softening agent is a phthalate, and its purpose is to increase the snappiness of filming, and improves its low-temperature performance.
Above-mentioned high molecular emulsion waterproof paint is characterized in that: described defoamer is silicone based water-based defoamer, and its purpose is to eliminate effectively the bubble that produces in the course of processing, reduces the coatingsurface defective.
Above-mentioned high molecular emulsion waterproof paint is characterized in that: described film coalescence aid is dibasic alcohol or alkoxide, its role is to reduce the film-forming temperature of coating, and it is constructed smoothly at a lower temperature, forms well behaved coating.
Above-mentioned high molecular emulsion waterproof paint is characterized in that: described reinforced filling is one or more in titanium dioxide, kaolin, lime carbonate, the talcum powder, and its purpose is to gain in strength, and improves weathering resistance, ageing resistance, resistance to tearing.
Above-mentioned high molecular emulsion waterproof paint as required, also can add mineral dye, makes coating have the effect of beautiful decoration.
Production technique of the present invention is: earlier macromolecule emulsion is added high speed dispersor and be uniformly dispersed, then softening agent, dispersion agent, defoamer, film coalescence aid are added, disperseed about 10 minutes, it is even reinforced filling to be added high speed dispersion again, after colloidal mill is milled to particle diameter gets final product less than 20 μ m.
Performance of the present invention meets JC/T 864-2000 standard:
1, tensile strength MPa: 〉=1.5
2, elongation at break %: 〉=300
3, low temperature flexibility :-20 ℃, flawless
4, watertightness: 0.3MPa, 30min is waterproof
5, solid content %: 〉=65
6, time of drying h: surface drying≤4, do solid work≤8
The present invention has following advantage:
1, adaptability is strong, can direct cold construction on basal planes such as dry or moist new old roof, vault, toilet.There is favorable elasticity to play and covers crackle or suppress the effect that crackle produces.
2, weathering resistance is strong, stable chemical performance, uvioresistant good endurance, waterproof and breathable.
3, safety and environmental protection, nonpoisonous and tasteless, do not burn, environment and personnel there are not any harm.
4, high-low temperature resistant has certain reflective, heat insulation, heat insulation effect.
5, acid and alkali-resistance has certain antiseptic property.
6, bonding strength height combines closely difficult drop-off with basal plane.
7, with low cost.
8, use range is extensive, is applicable to following occasion:
(1) is used to do the finish coat of newly-built roof waterproof layer or other water-proof material of roofing, as the protection cover of coiled material, coating;
(2) be used for the repairing or the renovation (need not remove old waterproof layer) of old roof;
(3) be used for outer surface of wall, bathroom metope, ground waterproof;
(4) be used for ground, tennis court making etc.;
(5) be used for slit between sealed doors and windows and the buildings, buildings expansion joint etc.
