Abstract
The invention discloses a preparation method of an antibacterial environmentally-friendly interior wall coating. The preparation method is characterized in that a film forming material adopted in the preparation method is a combination of an acrylic copolymer emulsion with diacetone activity functional groups and an acrylic copolymer emulsion with functional groups capable of stably complexing silver ions, so that the film forming property of the interior wall coating is excellent; special functional groups on molecular chains of the emulsion polymers can be complex with the silver ions to form a stable compound; meanwhile, the silver ions are safe, efficient and environmentally-friendly inorganic antibacterial agents, so that the coating has certain antibacterial property; other additives do not contain APEO (alkylphenol ethoxylates), limited metals and VOC (volatile organic compounds), so that the content of a prepared organic volatile substance approaches zero, and meanwhile, the other additives have synergistic interaction effects when being compounded to the coating; attapulgite and diatomite serve as packing and have certain effects on organic substance adsorption apart from having effects owned by the coating, so that the coating is relatively environmentally-friendly.
Description
Technical field
The present invention relates to the chemistry painting industry technical field, relate in particular to a kind of preparation method of antibacterial environment protection interior wall coating.
Background technology
Aqueous inner wall paint be a kind ofly construct easily, environmental friendliness, environment protection health, Chemicals that value-added rates is high.It is beautiful lastingly that it not only has the building material surfaces such as the construction wall of making, decorative building material, the function that increases the service life, also have decorative environment to give the function of Beautiful treat or eye-catching mark, along with the development of science and technology, aqueous inner wall paint progressively becomes a kind of functional strong and high fine chemistry product of environmental requirement.
Water emulsion paint for internal wall use at home is more and more general, all can be used in nearly all indoor decoration.In the past people only feel be aqueous product with regard to safety and environmental protection, but still can contain solvent and film coalescence aid in the actual aqueous product---be exactly usually said VOC value.In view of the harm of VOC, many countries have promulgated that relevant criterion limits the content of VOC in the coating products, and simultaneously, the public also more and more pays close attention to VOC in the coating to the impact of healthy and environment.In view of this, exploitation zero-VOC coating has become a main flow direction of following paint development.
The film coalescence aid that traditional aqueous inner wall paint well can add 1-2% for the paint film property performance helps the better film forming of filmogen; Simultaneously, also can add the 1-2% solubility promoter and have good freeze-thaw stability by coating, the low VOC product of some of existing market, to improve the paint film film-forming properties by adding the high film coalescence aid of boiling point mostly, because regulation is not calculated in VOC greater than the chemical substance of 250 ℃ of boiling points in the VOC detection method; The solubility promoter that also can add the few high polymerization of volatility simultaneously improves freeze-thaw stability.
This research topic of salient features that coating VOC is down to lower content and does not affect coating simultaneously is the theme that global coating industry is explored the way forward always, but in ultralow VOC products more of the same trade, can cause that also the performance of coating declines to a great extent simultaneously to the reduction of VOC.
In addition, because deterioration and the ecological damage of environment are serious, reduce the natural immunity function of human body; Simultaneously, various prevailing disease are but propagated rapidly, so people are also more and more higher to the demand that coating can have antibacterial.
In sum, this area need badly a kind of can antibiotic, again environmental protection, can also keep the interior wall coating product of good conventional application performance simultaneously.
Summary of the invention
