Description

A kind of elastic emulsion paint

Technical field

The present invention relates to a kind of coating, relate in particular to a kind of elastic emulsion paint with antisweat, antimildew function.

Background technology

The warehouse of China geographic most of cigar mill by north is a fixed temperature and humidity, and temperature remains on about 25 ℃.Owing to be the warehouse of putting tobacco leaf mainly, a large amount of tobacco leaf bisques are arranged in the air, in the time of winter, external temperature is too low, and wall has water of condensation, and tobacco leaf micronic dust and water of condensation mix, and are attached to wall surface.Because the composition of pipe tobacco is an organism, under this suitable temperature and humidity conditions, very easily grow mould in film coated surface, shortened the cycle that coating uses.The effect of common mould-repellant coating blocking-up mould-growth is not clearly, and general mould-repellant coating is not blocked the suitable growing environment of mould just to the restraining effect that plays of mould, and what make mould continues growth in adapt circumstance.The source of nutrition of the growth needs of mould is in various organism, the tobacco leaf micronic dust of cigar mill provides very abundant nutrition for mould, in addition, another of mould-growth must condition be that competent moisture, oxygen and suitable temperature (20～35 ℃) are arranged, the warehouse of cigar mill's fixed temperature and humidity also provides suitable condition for mould, and therefore, mould will breed in adapt circumstance fast, cigar mill all to be repeatedly remoulded every year, bring great inconvenience to production.

Therefore, a kind of have a better anti-mold effect, can prevent or delay body surface generation dewfall, can allow again film can mould fungus inhibition the breeding and the coating of growth become and be badly in need of the technical problem that solves now.

Summary of the invention

The technical problem to be solved in the present invention be for solve technological deficiency recited above, provide a kind of and can prevent or delay body surface generation dewfall, can allow again film can mould fungus inhibition breeding and the elastic emulsion paint of growth.

Take following technical scheme in order to solve technical problem the present invention recited above:

A kind of elastic emulsion paint comprises slurrying component and paint component, wherein,

Slurrying component and weight proportion thereof are:

Water: 8-10%; Propylene glycol: 2-5%; Dispersion agent: 0.4-0.8%; Wetting agent: 0.2%; Defoamer: 0.2%; Sanitas: 0.15%; Dry film mould inhibitor: 0.6%; Anatase titanium dioxide: 4-7%; Pearlstone: 20%; Calcined kaolin: 7%; Diatomite: 10%; Coarse whiting 800 orders: 8%;

Paint component and weight proportion thereof are:

Elastic emulsion: 30-40%; Film coalescence aid: 0.5%; Defoamer: 0.2%; PH conditioning agent 0.15-0.2%; 20% aqueous solution of thickening material: 4～5%; Flow agent: 1-1.5%; Surplus is a water.

Wherein, slurrying component and model thereof are respectively: dispersion agent Hydropalat 5040; Wetting agent

20; Defoamer Defoamer 334; Sanitas Alex F-251; Dry film mould inhibitor AlexN-254; Anatase titanium dioxide ZA-100; Calcined kaolin DB-80;

Paint component and model thereof are respectively: elastic emulsion SC-138; Film coalescence aid C-40; Defoamer FoamStar A-10; PH conditioning agent C-950; Thickening material HASE661; Flow agent DSX3020.

Compared with prior art, the present invention has following advantage:

(1) emulsion of the present invention adopts comparatively hydrophilic elastic emulsion, and the contact angle of reduction and water avoids the globule to form, and has also improved at the thick early stage resistance to cleavage of filming man-hour that spreads; Mould inhibitor is selected good dry film mould inhibitor, the validity and the persistence of the mildew-resistant that guarantees to film;

(2) do not require during the present invention constructs and convert water or convert water less, guaranteed the thickness of one-pass film-forming, reduced the number of times of construction, saved the engineering time, reduced cost;

(3) the present invention adopts mildew-resistant and antisweat principle of combining, and the growing environment of blocking-up mould has improved the work-ing life of filming;

(4) the present invention adopts the stronger multi-hole type filler (as perlite, diatomite etc.) of water-absorbent, has guaranteed the good performance of filming.In a humid environment, when metope had dew, the hygroscopic effect of material made to film and keeps dry, reduced the absorption of tobacco leaf flying dust; When the body of wall temperature raise, filming had ventilation property preferably and makes the moisture evaporation of filming get rid of, and prevented to film destructions such as hollowing, foaming to occur.

Elastic emulsion paint of the present invention is used for mould proof the growing of antisweat of the interior wall of cigar mill, and economical and practical, effect is remarkable, and production and accumulating are simple and convenient.

Embodiment

The present invention is a kind of interior wall function emulsion paint of high-grade elasticity with good antisweat mildew-resistant economic benefits and social benefits unification, constructional method can adopt brushing, roller coat, common spraying or Airless spraying, preferably adopt and do not convert water or convert the water construction less, once obtain thicker filming, reduce the brushing number of times, guarantee good the adhering to of coating.

Wetting agent among the present invention

The 20th, nonionogenic tenside, composition is polyether-modified polysiloxane or amber sulfonate, a kind of novel low-foaming wetting agent, unique high many hydrophobic groups of cladodification structural polymer, the behavior of performance good wet, and do not form stable bubble, and be a kind of wetting agent with their defoaming function, the surface tension of the aqueous solution (0.5%) is 20 dynes per centimeter ²Thereby, reduced the generation of bubble, reduced the disadvantage of paint film;

Defoamer employing different steps among the present invention is added different types of defoamer and is reached good defoaming effect.Defoamer Defoamer334 is a kind of efficient liquid defoamer, has long-acting defoaming, it disperse, press down bubble in the process of lapping, broken bubble is remarkably productive, be particularly useful in the emulsion paint of viscosity higher of roller application.Defoamer FoamStar A10 system has adopted the froth breaking material FoamStar and the novel mineral oil based compound of special mineral oil synthetic of special molecular structure, and broken rill is had positive effect, adds in the paint stage.

Sanitas is a kind of broad-spectrum sterilization sanitas of performance brilliance for Alex F-251 among the present invention, its main component is the mixture of N-methyl-isothiazolinone and 5-chloro-isothiazolinone, be used for the emulsion paint in-can preservation, wide spectrum, long lasting various bacteria, fungi and the yeast killed, consumption is low; Toxicity is low, and working concentration is harmless fully; The discharging noresidue can not cause pollution of circulation to environment; Alex N-254 is applied to the mildew-resistant of coating dry film, and economy easy to use, its main component are daconil M, and strong disinfecting can be comparable with mercury type biocide mildewcide; Solubleness is extremely low in water, water-tolerant.

During the present invention was raw materials used, elastic emulsion SC-138 was provided by BASF AG; Dispersion agent Hydropalat5040, wetting agent 20, sanitas Alex F-251, dry film mould inhibitor Alex F-254, defoamer Defoamer 334, FoamStar A-10, thickening material HASE661, film coalescence aid C-40, PH conditioning agent C-950 provide by Shenzhen Haichuan Chemical Technology Co., Ltd.
