Embodiment
A kind of exterior wall low PVC emulsion paint based on water resistant type dispersion agent of the present invention, the parts by weight of each component are: 170 parts, water, KPA dispersion agent 3.5 parts, P-23 water resisting property dispersion agent 2 parts, FG-5 suds suppressor 1 part, white light color stuffing 370 parts, Texanol film coalescence aid 22 parts, polyurethane associative thickener 2 parts, pure-acrylic emulsion 400 parts, PH conditioning agent 2 parts, defoamer 2 parts, acrylic thickener 3 parts.
Owing to have employed KPA dispersion agent and P-23 water resisting property dispersion agent, KPA dispersive ability is strong, and the consistency fabulous with system can not affect coating gloss simultaneously; Acrylic copolymer sylvite, avoids the drawback that sodium salt is saltoutd; Itself there is low bubble, and effectively can soak the surface of pigments of water unfit to drink, therefore can without the need to adding wetting agent in addition, even if this dispersion agent adds and excessively also can not produce detrimentally affect to system.P-23 is a kind of hydrophobic nonionic copolymer dispersant, and film forming water tolerance is outstanding, also can be used as film forming matter; Stablize color stuffing with sterically hindered effective anchoring group effect, HLB value is low, effectively can solve loose colour and grow dim.Cooperatively interacted by these two kinds of dispersion agents and polyurethane associative thickener, acrylic thickener, the exterior wall low PVC emulsion paint of weathering resistance, water-tolerant can be produced.
In exterior wall latex paint, we do not use HEC class thickening material at suggestion.There is experiment to prove, be not so good as the coating paint film by HASE class and the thickening of HEUR class, so the water resisting property of paint film can reduce by the coating paint film compactness of HEC thickening.The present invention uses T-33 and PU-40 in exterior wall latex paint.Described polyurethane associative thickener is PU-40 polyurethane associative thickener.PU-40 has outstanding thickening leveling effect, possesses comparatively senior middle school and to cut and height cuts viscosity, provide excellent can opening effect and dry film fullness ratio, the splashing in construction process can be improved to minimum.Described acrylic thickener is T-33 acrylic thickener.T-33 alkali activation thixotropic thickening material, consumption is low, extremely strong anti-settling effect, improves finished product paint package stability, unique therein is cross-linked association mechanism makes product have high yield value when stationary state (shearing rate is zero), thus solves point water and a loose colour problem.
From the viewpoint of gloss of film degree, ventilation property and weathering resistance etc., emulsion content general control in coating total amount 20% ~ 60% not etc.Our general little recommendation benzene emulsion in exterior wall latex paint formula, require not too high occasion (as in priming paint and floating coating formula) in weathering resistance, the phenylpropyl alcohol of excellent performance and pure-acrylic emulsion are arranged in pairs or groups and are used by our suggestion.In exterior wall latex paint, weathering resistance and contamination resistance are paid close attention to always the most, and these two performances provide by synthetic emulsion, so we are when selecting emulsion, the balance between second-order transition temperature (Tg) and minimum film-forming temperature (MFT) must be considered.The thickening efficiency of HEUR class thickening material depends on character and the concentration of dispersed particle in formula (i.e. synthetic emulsion).For the formula of cellulose thickener, be used interchangeably different emulsions, and for HEUR type thickening material, use different emulsions instead, viscosity but there occurs and changes widely.We observe in an experiment, (as National Starch pure-acrylic emulsion 2800 in the emulsion system that some hydrophobicity is strong, ROHM AND HAAS pure-acrylic emulsion AC-261), the associative thickening of PU-337 and PU-40 is very competent, consumption much less in the amount ratio wetting ability emulsion system of thickening material.The pure-acrylic emulsion RS-2806 of Ahmedabad richness (accounting for 40% of coating total amount) is used in exterior wall low PVC formula, excellent combination property in the present invention.
Further, described PH conditioning agent is AMP-95PH conditioning agent.
Further, in order to ensure the storage effect of painting, P-123 fungicidal preservative 2 parts is also comprised.
Further, ethylene glycol 15 parts is also comprised.Ethylene glycol is freeze proof and anti-skinning agent, because exterior wall paint not only faces this anti-water problem, is also faced with freeze proof problem.The present invention with the addition of ethylene glycol 15 parts, greatly strengthen the anti-freezing property of paint.
Further, white light color stuffing is made up of rutile titanium white 170 parts, sericite in powder 50 parts, calcined kaolin 50 parts, wollastonite powder 100 parts.White pigment rutile titanium white powder, should regulate the addition of titanium dioxide according to the depth of colored paint color, dark-colored paint titanium dioxide should add less or not add, and general addition not to control at 5%-10% not etc.(white paint generally adds 8%-20%); Be not suitable for adding anatase thpe white powder and zinc sulfide white.Filler: be good with the pigment extender that granularity is not too thin, particle is thin, and in per unit volume, the number of particle is large, and easily see the powder phenomenon-tion on surface, this area being actually pigment and base-material increases, the result of weathering resistance variation.Calcined kaolin: good covering performance, excellent suspension and anti-moisture absorption, shock resistance.Mica powder: strengthen film, antipollution, uvioresistant.Wollastonite powder: part dry hiding power, hardness is good, uvioresistant.Be coated with in latex paint formulation in high-performance exterior wall face, we are very recommendation calcium carbonate not, and Yin Qiyi rises " bloom " in film coated surface, general only in primary coat or middle painting latex paint formulation.In exterior wall latex paint formula, we generally do not use light calcium carbonate and talcum powder.We use 8% rutile titanium white, 10% calcined kaolin, the wollastonite powder of 15%, the water-ground limestone of 12% in exterior wall high PVC formula, in low PVC white exterior wall paint formula, use 17% rutile titanium white, 5% mica powder, 5% kaolin, 10% wollastonite powder (accounting for coating total amount), properties is excellent.
A kind of manufacture craft of the exterior wall low PVC emulsion paint based on water resistant type dispersion agent, successively by 170 parts, water, KPA dispersion agent 3.5 parts, P-23 water resisting property dispersion agent 2 parts, P-123 fungicidal preservative 2 parts, ethylene glycol 15 parts, FG-5 suds suppressor 1 part, rutile titanium white 170 parts, sericite in powder 50 parts, calcined kaolin 50 parts, wollastonite powder 100 parts to add in container and tells that dispersion is after 20 minutes, slow down stirring velocity, add Texanol film coalescence aid 22 parts more successively, PU-40 polyurethane associative thickener 2 parts, pure-acrylic emulsion 400 parts, AMP-95PH conditioning agent 2 parts, defoamer 2 parts, T-33 acrylic thickener 3 parts is mixed to form.
