Description

A kind of high resistant interior wall coating and preparation method thereof
Technical field
The present invention discloses a kind of coating, specifically, is a kind of high resistant interior wall coating, and the present invention also discloses the preparation method of this coating, belongs to coating preparing technical field.
Background technology
Along with the continuous progress of society, people have had higher requirement to interior wall coating, and except ornamental, people more focus on the feature of environmental protection and high-performance.Tradition interior wall coating, as emulsion paint, has good decorative property, with low cost, the feature of easy construction, but because paint film itself is more loose, cannot form real closely knit paint film, there is ventilation property, thereby do not reach good resistant effect.
Water-base epoxy wall paint is compared emulsion paint and is had more following clear superiority: coatingsurface densification, be not easy to leave a trace, scribble water or environment-friendly type solvent of child is easy to scrub, and coating has superpower scrub resistance, not loss of gloss, colour-fast of coating after cleaning.
The aqueous epoxy coating of selling on the market is now selected conventional liquid bisphenol A type epoxy resin and aqueous amine solidifying agent mostly, although this collocation can solve the series of problems such as resistant, but its feature of environmental protection and long-time operation cannot be met the need of market, also just cannot obtain universal use.
Summary of the invention
For the problems referred to above, the invention provides a kind of preparation method simple, environmental protection, high resistant interior wall coating.
The present invention also provides a kind of preparation method of above-mentioned coating.

Wherein: No. 1 described auxiliary agent is made up of 0.08-0.12 mass parts defoamer, 2.2-2.6 mass parts thickening material and 0.2-0.8 mass parts emulsifying agent; No. 2 described auxiliary agents are made up of 0.3-0.8 mass parts defoamer and 0.2-0.7 mass parts sanitas; No. 3 described auxiliary agents are by 0.3-.07 mass parts emulsifying agent, 0.2-0.4 mass parts wetting agent, 0.05-0.15 mass parts dispersion agent, 1.2-1.8 mass parts defoamer composition.
Further, in above-mentioned high resistant interior wall coating, the FoamStar A10 that described defoamer is Kening Co.,Ltd or the BYK-022 of Bi Ke chemistry.
Further, in above-mentioned high resistant interior wall coating, described thickening material is WT-105A or Akzo Nobel's polyurethane thickener PUR2150 of the modest chemistry of moral.
Further, in above-mentioned high resistant interior wall coating, described emulsifying agent is ASA-150 emulsifying agent of Guangdong fine chemistry industry institute.
Further, in above-mentioned high resistant interior wall coating, described aqueous epoxy resins is bisphenol A-type aqueous epoxy resins.
Further, in above-mentioned high resistant interior wall coating, described wetting agent is the BYK-187 of Bi Ke chemistry or the W-519 of the modest chemistry of moral.
Further, in above-mentioned high resistant interior wall coating, the W19 of the modest chemistry of the preferred moral of described dispersion agent or the BYK-190 of Bi Ke chemistry
Further, in above-mentioned high resistant interior wall coating, described waterborne curing agent steps aradur 3985 waterborne curing agents by the Hensel of 15.5 ~ 30 mass parts or U.S.'s gas Sunmide WH-1000 waterborne curing agent forms.
Further, in above-mentioned high resistant interior wall coating, described color stuffing is made up of 10 ~ 15 parts of calcium carbonate, 20-30 mass parts titanium dioxide, 4-5 mass parts calcined kaolin, 5-6 amount part zinc oxide.
After of the present invention, a technical scheme is such: a kind of preparation method of high resistant interior wall coating, comprises the steps: 1 successively) divide and take A component and B component by quality claimed in claim 1; 2) raw material described in the A component slurrying stage is stirred to 60~120min in 1000~1200rpm, so that slurry fineness is less than 30um, and then add the raw material described in the paint stage, stir 30~60min with 600~800rpm, filter, obtain component A; 3) starting material described in B component are stirred to 60~90min in 1000~1200rpm and mix, filter, obtain B component; 4) before application, component A and B component are mixed with 1:1, stir and get final product.
Inventive principle: the coating that epoxy resin coordinates solidifying agent to prepare, in film process, there is chemical crosslink reaction, the webbed crosslinked paint film of shape, by the ratio of reasonable adjustment resin and color stuffing, makes the coating of preparation brush the curing rear airtight physics paint film that forms.The present invention's use pure-acrylic emulsion of arranging in pairs or groups, reduces the PVC of coating on the one hand, makes resin can be good at coated color stuffing, forms closely knit paint film, improves anti-pollution characteristic; On the other hand by emulsification by pure-acrylic emulsion grafting above aqueous epoxy resins, utilize steric effect, play shielding effect, thereby reach ageing-resistant effect.
Compared with prior art, that the present invention selects is stable, the aqueous epoxy resins of environmental protection is as the main filmogen of interior wall coating, then selects collocation part pure-acrylic emulsion, color stuffing ratio in rational allocation paint film, to form the physics paint film of long-acting densification, thereby reach the object of high resistant.
