After the anti-foaming operation is performed, anticorrosion agent, film forming auxiliary agent, residual emulsion, thickening agent and water are added and evenly stirred at the rotational speed of 300rpm to 700 rpm, and the single component waterproof coating is obtained. The method has the advantages that the construction technology of the coating is simple and convenient, the film-forming process is finished mainly depending on the volatilization of the water and the interfusion of the latex particles, no VOC is discharged, no organic solvent is effused, the single component waterproof coating has no environmental pollution and combustion, the construction is safe, and the coating is an environmental protective-type single component waterproof coating.
Description
Technical field
The present invention relates to a kind of waterproof paint, relate in particular to a kind of environment protection type single-component waterproof paint of VOC free discharging.
The invention still further relates to a kind of preparation method of waterproof paint.
Background technology
Buildings generation seepage not only can the spoiled work interior decoration, equipment, and severe patient also can destroy engineering structure, makes its forfeiture functions of use, leads to the life security of scrapping even jeopardizing people.Adopting waterproof technique to prevent the infiltration of buildings and leaking is a kind of waterproof method of just having brought into use late 1950s.Waterproof paint is viscous liquid at normal temperatures, can form jointless waterproof coating after coating is solidified, and suits especially to construct at detail structure places such as facade, negative and positive angle, narrow places, possesses bonding and two kinds of effects of waterproof simultaneously.
Waterproof paint can be divided into solvent-borne type, response type, emulsion-type three major types by its state and form.Response type contains a large amount of solvents usually by liquid macromolecule prepolymer and the film forming class coating of respective substance generation chemical reaction.Wherein, solvent based coating and response type coating can be discharged volatile organic compounds (VOC) to atmosphere and be polluted in production and construction process, VOC has stimulation and destruction to central nervous system, hemocytopoietic organ, the respiratory system of human body, seriously can cause twitching, go into a coma even death, therefore, VOC is very big to human health damage.
Various countries have launched respectively the rules of VOC discharging in the world, require manufacturer's production to have the emulsion-type waterproof paint of low VOC discharging, environmental protection, therefore, the waterproof paint with low VOC discharging, environment-friendly type has been trend of the times, becomes the technical problem that solution is badly in need of in each manufacturer.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome technological deficiency recited above, a kind of environment protection type single-component waterproof paint and preparation method of VOC free discharging are provided, film and the basal plane, coating, finish coat of waterproof paint all can bond firm, formation integral seamless, the form compact and stable elasticity layer that discharges water.
In order to solve technical problem recited above, the present invention takes following technical scheme:
The invention provides a kind of single-component waterproof coating material, comprise that component and weight percent thereof are as follows:
Emulsion: 40～60%;
Solubility promoter: 1～10%;
Dispersion agent: 0.1～1%;
Wetting agent: 0.1～1%;
Defoamer: 0.1～1%;
Color stuffing: 30～50%;
Film coalescence aid: 1～5%;
Thickening material: 0.2～2%;
Sanitas: 0.1～1%;
Surplus is a water, and above each component per-cent sum is 100%.
Wherein, described color stuffing is made up of titanium dioxide, kaolin and wollastonite, and wherein, titanium dioxide accounts for 40～50% of color stuffing weight, and kaolin accounts for 35～45% of color stuffing weight, and wollastonite accounts for 10～15% of color stuffing weight.
Titanium dioxide is best and the most frequently used white pigment, the opacifying power height, and reducing power is strong, good stability; Kaolin can reduce the coating cost, plays skeleton function again, increases coating thickness, improves physical strength, wear resistance etc.; Wollastonite has certain opacity, can improve the moisture-proof film, and high zero diopter effect is arranged.
Color stuffing volumetric concentration (PVC) will directly have influence on the tensile strength and the elongation at break thereof of coating.So, add that an amount of auxiliary agent guarantees that color stuffing disperses, the viscosity of coating and package stability etc.
As a kind of preferred version: the solubility promoter that the present invention selects is a propylene glycol; Dispersion agent is a polyacrylic acid sodium salt, can disperse inorganic color stuffing effectively, and is adsorbed on the color stuffing surface, simultaneously and between the polymer emulsion good consistency is arranged, and odorlessness does not contain solvent; Wetting agent is a nonionogenic tenside, and composition is polyether-modified polysiloxane or amber sulfonate, and its concentration is that the surface tension of 0.5% aqueous solution is 20 dynes per centimeter
2Defoamer is not for containing the defoamer of mineral oil and organic solvent.Thickening material is urethane or the polyethers associative thickener that does not contain solvent and do not contain alkylphenol.Film coalescence aid is propylene glycol list oleate EFC-100, and is non-volatile in the film process; Sanitas is an isothiazolinone, does not contain formaldehyde, and VOC is extremely low.
Emulsion is as the single-component waterproof coating material main film forming substance, be related to the water tolerance of filming, hardness, snappiness etc., also be related to performances such as cohesive strength to ground, directly influence the use properties of coating, therefore, emulsion of the present invention adopts benzene emulsion, its solids content is greater than 45%, second-order transition temperature is less than 1 ℃, and pH value is 6～7, and emulsion particle diameter is 0.1～0.5 μ m.
The present invention also provides the preparation method of single-component waterproof coating material, step comprises: the emulsion with 50～80%, solubility promoter, dispersion agent, wetting agent mixes with 40～60% defoamer, with rotating speed is that 300～700rpm stirs, in whipping process, add color stuffing, rotating speed with 2000～4000rpm disperses afterwards, obtain the slurry of fineness less than 50 μ m, add the residue defoamer then, add sanitas after the froth breaking again, film coalescence aid, the residue emulsion, thickening material and water, with rotating speed is that 300～700rpm stirs, and obtains single-component waterproof coating material.
The present invention adopts single component emulsion-type waterproof paint, and its main film forming substance macromolecular material is with atomic little particle stabilized being suspended in the water.Such coating application technology is simple and convenient, and film process is finished by moisture evaporation and emulsion particle fusion, the VOC free discharging, and organic solvent-free is overflowed, and is free from environmental pollution, do not burn, and construction safety is a kind of environment-friendly type mono-component waterproofing paint.
