Description
Technical field the present invention relates to a kind of coating, particularly a kind of aqueous woodware paint with bactericidal function.
Mostly be the solvent-borne type wood lacquer in the present traditional wood lacquer of background technology, based on solvent borne polyurethane and pyroxylin(e)finish, this wood lacquer since organic volatile total amount (VOC) than higher, environment is polluted, influence people's health, in developed countries such as America and Europes, consumption is downtrending year by year, aqueous woodware paint has market outlook preferably then because of free from environmental pollution, and development was very fast in recent years.
The aqueous woodware paint that exists at present on the market has two types of single component and two-packs, and the used film forming thing mainly contains aqueous alkide resin, ACRYLIC EMULSION, aqueous polyurethane dispersion and aqueous epoxy resins etc.Because the price of two-pack wood lacquer is more expensive, a lot of products adopt the single component type, what for example, publication number was 1473894 and is called just to relate in the patent application of " a kind of green environment protection water soluble woodenware paint " a kind of single component uses the aqueous woodware paint of ACRYLIC EMULSION as film forming matter.Publication number is also to relate to a kind of mono-component aqueous wood lacquer in 1464013 patent applications that are called " environment friendly aquosity woodware nano paint ".These wood lacquers VOC content is low, and environment is difficult for producing pollutes, but the function that the said aqueous woodware paint of these patents does not have bactericidal and purifies air.Shortcomings such as in addition, aqueous woodware paint ubiquity hardness in the market is low, resistance to blocking and contamination resistance difference.
Summary of the invention the purpose of this invention is to provide a kind of aqueous woodware paint with bactericidal air purification function, this lacquer higher hardness of filming, and have good resistance to blocking and contamination resistance.
The objective of the invention is to be achieved through the following technical solutions: a kind of aqueous woodware paint with bactericidal air purification function, comprise A, B two portions component, the concrete component and the weight percent of A part are: film coalescence aid 5.5-8.0; Dispersion agent 0.3-0.5; Wetting agent 0.2-0.4; Solubility promoter 0.8-1.2; Pure water 2.0-3.0; Flow agent 0.2-0.5; Thickening material 0.1-0.2; Tensio-active agent 0.1-0.2; Defoamer 0.2-0.5; The mixture 1.2-1.5 of nano silicon and nano titanium oxide; The concrete component and the weight percent of B part are: aqueous polyurethane emulsion 75.0-85.0; Water-based wax emulsion 4.0-5.0.
Aqueous woodware paint with said components has bactericidal, the effect that purifies air, the principle of its foundation is, nano titanium oxide has photocatalysis, after nanoparticle is subjected to photon irradiation greater than the energy gap energy, electronics transits to conduction band from valence band, it is right to produce electronics-hole, because electronics has reductibility, the hole has oxidisability, they react with the water and the oxygen that are adsorbed in the surface respectively, generate highly active hydroxyl free radical and ultra-oxygen anion free radical, these free radicals can destroy bacterial film and the inner organized enzyme of germ, play the bactericidal effect, simultaneously, these free radicals can also with airborne formaldehyde, ammonia, obnoxious flavoures such as benzene react, and make them change into innoxious substance.
The present invention uses aqueous polyurethane emulsion as film forming matter, and this emulsion is divided into two classes, and a class is an oil modified urethanes, adds vegetables oil during preparation, thereby certain hydrophobicity is arranged after the film forming, as suitable prestige A68.Another kind of is pure polyurethane-type, adopts hydrophilic compounds such as dihydroxypropionic acid in the preparation, forms anionic emulsion through amine chain extension reemulsification, has characteristics such as higher hardness, snappiness and wear resistance, water tolerance, weather resistance, chemical resistant properties.Simultaneously, because polyether polyols with reduced unsaturation has cutting, as adopting the molecular designing principle, in conjunction with new synthesizing cross-linked technology, can control the The Nomenclature Composition and Structure of Complexes that is coated with membrane polymer effectively, the performance that aqueous polyurethane is filmed is equivalent to or surpasses traditional solvent-borne type wood lacquer.
The present invention has used nano silicon.This functional materials can improve hardness, antiblocking and the anti-stain characteristic of filming effectively.
The tensio-active agent that uses among the present invention is fluorochemical surfactant, methyl class silicone surfactant.This promoting agent can reduce the surface tension of water-borne coatings, causes film coated surface defectives such as bubble, flake, tangerine peel to occur thereby overcome owing to surface tension difference is excessive.
The present invention has used water-based wax emulsion.The last buoyancy of this water-based wax emulsion utilization itself and ball rolling principle can improve the slipperiness of filming, anti-after tackiness, water tolerance, can also protect film coated surface not to be subjected to the influence of mechanical wear, improve the surperficial feel of filming.
The defoamer that the present invention uses is the dimethyl siloxane defoamer.Experiment showed, that this defoamer is better than the effect of mineral oil defoaming agent.
The said preparation method with aqueous woodware paint of bactericidal air purification function of the present invention may further comprise the steps:
(1), the mixture with film coalescence aid, dispersion agent, wetting agent, solubility promoter, pure water, flow agent, thickening material, tensio-active agent, defoamer, nano silicon and nano titanium oxide in the A part disperses in the dispersion machine high speed, dispersing speed is 1500-2000 rev/min, and jitter time is 40-60 minute;
(2), the water-based wax emulsion in the B part is slowly added under whipped state in the aqueous polyurethane emulsion,
Mix in stirrer, the stirrer rotating speed is 200-400 rev/min, and the time is 30 minutes;
(3), will under whipped state, slowly add in the product of step (2) through the product that step (1) obtains, in stirrer, mix, the stirrer rotating speed is 200-400 rev/min, the time is 30-40 minute.
(4), product sieves, get product.
The said aqueous woodware paint of the present invention has following advantage: one, have good bactericidal function and the effect that purifies air; Two, have higher hardness and good resistance to blocking and contamination resistance.
