Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for skin surface and decoration has high dirt resistance, hides the elastic coating of crackle ability, belongs to chemistry painting industry technical field.
The current domestic whole elastic coating market of making a general survey of of background technology, most product is only limited to and possesses elastomeric feature, and its water tolerance and water-repellancy are poor, and tensile strength is low, and sticking power is general.Because it is not water-fast, non-watertight, at its paint film after rain drop erosion, will entirety peel off, or because the difference of water ratio causes cracking or peels off, rainwater just infiltrates metope corrosion metope.Because the contamination resistance of elastic coating is poor, construction is easily subject to being suspended in the dust in atmosphere afterwards, the pollution of oily matter is polluted coating surface simultaneously.For example publication number CN1737069A name is called the elastic coating relating in the patent application of " decoration of exterior wall elastic coating and manufacture method " and also has the problems referred to above.These disadvantages that exist have at present had a strong impact on its protection to basic unit and decorative effect having.Therefore research has individual layer elastic coating significant of good contamination resistance, high-effective water-proof.
Summary of the invention the object of this invention is to provide a kind of modified acroleic acid highly effective water-proof elastic dope, and this elastic coating not only has snappiness, also has high-effective water-proof, excellent contamination resistance, tensile strength is good, can significantly improve the advantage such as cracking performance of body of wall.
Concrete component and the part by weight of a kind of modified acroleic acid highly effective water-proof elastic dope of the present invention are: water: 10-20%; Multifunctional assistant: 0.1-0.2%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Defoamer: 0.3-0.8%; Propylene glycol: 1.5-3.0%; Rutile type Titanium Dioxide: 16-20%; Process white: 6-8%; Water-ground limestone: 5-8%; Opacifying polymers: 3-5%; Modified acrylic acid emulsion: 38-45%; Texanol:0.8-1.5%; Stain resistant auxiliary agent: 0.5-1%; Sanitas: 0.1-0.2%; Thickening material: 0.6-0.9%.
In general, the elasticity of elastic coating and the contamination resistance relation that is inversely proportional to, coating has lower contamination resistance under high-elastic state.The pollution channel of paint film mainly contains organism adhesion, electrostatic adhesion and imbedibility and pollutes.The film of stain resistance excellence, from the angle that prevents from adhering to, the film hard, anti-electrostatic effect good and surface smoothing has been considered to, as the angle from decontamination, the clean effect of hydrophilic film surface rainwater and surface uniform pollute and film that the rain mark that causes and non-the manifesting effect of spot have been considered to.
The present invention can form rigidity, the soap-free emulsion that contains special hydrophilic radical of antistatic and surface smoothing film, make paint film not only have snappiness also have antistatic, paint film is level and smooth, hydrophilic advantage, thereby make that elastic coating possesses snappiness, high-effective water-proof, has excellent water-resistance, the performance of stain resistant.
The emulsion that the present invention uses is the synthetic copolymer emulsion of organosilicon, in order to give film basic physical properties, there is again the performances such as excellent stain resistant, film coated surface is designed to wetting ability, make emulsion particle surface have effective hydrophilic functional group, thereby the water tolerance of making and wettability while also deposit, and sticking power is good.
The Rutile type Titanium Dioxide that the titanium dioxide that the present invention uses is made for chlorination process, is characterized in having high gloss, fabulous color, opacifying power and dispersed and good exterior durability.Opacifying power, weathering resistance and the chalking resistance close relation of its performance and film.
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, by this dispersion agent, can surround a layer charge at color stuffing particle surface, make repulsion mutually between particle, thereby reach the effect of stable slurry.
The present invention use Opacifying polymers be hollow polymer spheroid, can show extremely strong covering performance, improve coating contamination resistance (dirt pickup resistant), strengthen outdoor tint retention.
The stain resistant auxiliary agent that the present invention uses is for nano modification stain resistant auxiliary agent, and in coating film process, nanoparticle plays hinge point effect, and the organic polymer hinge of line style is reticulated to structure, improves film coated surface hardness; By reducing the pore dimension of film, improve smooth coating degree; By reducing film static charge, reduce the absorption of atmospheric dust; Make film possess good self-cleaning, improved the stain resistant performance of coating.
Thickening material used in the present invention mainly contains newton-type nonionic polyoxyalkylene class rheology modifier and the swelling class thickening material of alkali.
Production technique of the present invention is mixed the component of above-mentioned weight ratio at normal temperatures, under stirring at low speed, add part water, multifunctional assistant, wetting agent, dispersion agent, early stage defoamer, propylene glycol, titanium dioxide, process white, water-ground limestone, after high speed dispersion, be ground to after slurry fineness≤50um, stirring at low speed adds emulsion, Texanol, later stage defoamer, sanitas, thickening material, stain resistant auxiliary agent, excess water, meet the requirements of after viscosity, stirring at low speed 10min again, then through checking, filter, weigh packing.
Below embodiment, be one embodiment of the present of invention.
