Description
Technical field
The present invention relates to woodwork coating correlative technology field, particularly relate to a kind of preparation method with the waterborne polyurethane wood coatings of antibacterial effect.
Background technology
Woodwork coating is the important component part of coatings industry, refers to the coating on the equipment prepared for starting material such as solid wood board, wood grain panel, hard rubber sheet, fiberboards, is mainly applicable to furniture, floor, stationery sports goods, musical instrument and constructional ornamental material etc.At present, the aqueous polyurethane coating that high-performance and low VOC content combine, because polyurethane molecular has cutting, in conjunction with new synthesis and crosslinking technological, can effectively control system component and structure, thus make it have good film formation at low temp, high temperature resistant after-tackiness, high strength, wear resistance, the feature of environmental protection etc., therefore become one of coating variety with fastest developing speed.As the Beijing National swimming center i.e. artistic floors of " the Water Cube " what use is exactly the aqueous polyurethane coating that Bayer Material Science company provides.
Since nineteen thirty-seven Germany professor Otto.Bayer first synthesis of polyurethane (PU), because urethane resin has excellent chemical property and mechanical-physical, be widely used in chemical field.Polyurethane coating is widely used in the fields such as petrochemical equipment, ocean, boats and ships, electromechanics, vehicle, weaving, leather, timber, wood lacquer, plastics, building, waterproof paint because having excellent wear resistance, snappiness, weather resistance, preservative property and insulativity.The development of urethane is broadly divided into two stages: the first stage is mainly based on solvent-borne type; Subordinate phase is the stage that aqueous polyurethane develops rapidly.Traditional solvent borne polyurethane contains a large amount of organic solvents and a certain amount of free isocyanate, affects the healthy of people and living environment, and the residual isocyanate monomer particularly in solvent-type double-component urethane, toxicity is high.Along with the raising of human life quality, environmental regulation is also more and more stricter, and various environmental regulation has strict restriction to the quantity discharged of volatile organic compounds (VOC), the content of hazardous solvent.And aqueous polyurethane is dispersion medium due to it with water, not only has the advantages such as nontoxic, nonflammable, free from environmental pollution, energy-conservation, safe and reliable; Also there are some important performance characteristics of solvent borne polyurethane simultaneously, aqueous polyurethane coating by high for the hardness of polyurethane coating film, strong adhesion, corrosion-resistant, solvent resistant is good etc., and advantage combines with the low VOC content of water-borne coatings, meet " three prerequisites " (resource of development coatings industry, the energy, pollution-free) and " four E principles " (economic ECONOMY, efficiency EFFICIENCY, ecological ECOLOGY, energy ENERGY) and the requirements of the times day by day strengthened adapt.Therefore aqueous polyurethane coating obtains a wide range of applications in recent years.And be that the aqueous polyurethane of dispersion medium has the advantages such as nontoxic, free from environmental pollution, energy-conservation, easy to operate with water, and Application Areas is extensive.Along with the restriction of various countries' environmental regulation to VOC and the attention to environmental protection, aqueous polyurethane is obtained and develops faster, be widely applied in fields such as fabric, leather, tackiness agents, just progressively replace solvents type polyurethane.From now on along with the raising of the progress of technology and the strict control of VOC content and people's Environmental Safety and health perception, water-based PU will become an important developing direction.
Urethane develops from the thirties in 20th century; and the research of a small amount of aqueous polyurethane is just had in the forties; vulcabond emulsification in water, under emulsifying agent and protective colloid exist, is successfully prepared polyaminoester emulsion by nineteen forty-three Germanization scholar Schlack first.The toluene solution of diisocyanate based base polyurethane prepolymer for use as is scattered in water by the researchist of nineteen fifty-three Du Pont company, has synthesized aqueous polyurethane with diamine chain extension.But polyurethane material science is at the early-stage at that time, and aqueous polyurethane does not also come into one's own, until just industrialization first in 1967, within 1972, polyurethane aqueous dispersion body is formally produced in enormous quantities as leather coating by Beyer Co., Ltd.The seventies and eighties in 20th century, some aqueous polyurethane products of U.S., moral, Deng state develop into actual production and application from advanced development, there are the aqueous polyurethane product-feed of the multiple trade mark in some companies, as the aqueous vinyl adhesive for polyurethane KR series etc. of the series such as the series such as DispercollKA of German Bayer company, X and E of Wyandotte chemical company of the U.S., Japanese silver dollar industry companies.From the later stage nineties 20th century, the Application Areas of aqueous polyurethane starts constantly to widen, and coheres, has certain industrial applications in automotive upholstery, coating, coating etc. at PVC.
China was from the aqueous polyurethane that begins one's study in 1972, and the nineties in 20th century, the PUD technological achievement of University of Anhui, Dandong light industry research institute, Chengdu Univ. of Science & Technology (branch of existing Sichuan University) etc. is all successively converted.At present, China has many fields applying waterborne polyurethane product, but wherein many expensive goods still can not be self-supporting, and therefore independent research high-performance water-based polyurethane just becomes one of the most popular direction of domestic polyurethane field.
For improving mechanical property and the chemical resistance of AQUEOUS POLYURETHANE DISPERSION COATINGS further, often introducing reactive group and being cross-linked.Crosslinked method mainly contains 3 kinds: (1) interior crosslinking, namely introduces three-dimensional structure when prepolymerization, or uses tertiary amine chain extension during chain extension in water, but the introducing of three-dimensional structure easily causes gel to occur.As Olin company of the U.S. develops the new technology using urine butanone to make internal crosslinker recently, obtained stable latex system.This technology utilizes excessive diamine to move in emulsion particle, forms biuret linkage, bring out auxiliary crosslinking reaction and make with the urine butanone radical reaction in polyurethane skeleton.By the mechanical property and the solvent resistance that use urine butanone internal crosslinker can improve monocomponent waterborne polyurethane coating; (2) self-crosslinking method, namely introduces the vegetables oil or its lipid acid that contain unsaturated link(age) in molecular chain when aqueous polyurethane synthesizes, carrys out catalysis self-crosslinking by metal catalyst (as cobalt, manganese, calcium salt).This contributes to reducing particle diameter, the surface tension of adjustment polyurethane aqueous dispersion body, improve polyurethane aqueous and fall apart varnish to the penetrating power of timber pore and the speed and the degree that improve particles coalesce, shorten the time of drying of film, thus the film of availability excellence.As R9403, R2001 etc. of the Neoreslins of specialty chemicals company of the U.S..This modified cost that also can reduce coating, improves the drying property of coating, fillibility, transparency, gloss, wet adhesion and levelling property.One-pack then developed by document, this coating has excellent outside durabitity, shock-resistance, resistant, scratch resistance and chemical resistance etc., indices meets or exceeds traditional solvent borne polyurethane coating, is widely used in paint of wooden floor, external application coating varnish and coatings for furniture; (3) external crosslinking method, namely adds linking agent.The structures shape of aqueous polyurethane the composition of outside cross-linking agent, and outside cross-linking agent conventional time hydroxyl, amino in polyurethane molecular has water dispersible polyisocyanate, nitrogen heterocycle propane compound, aminoresin etc.; Time in polyurethane molecular with carboxyl, the compound of conventional polyamine, cyclopropane and some metallic compound, as Al (OH)
3, Ca (OH)
2etc. making outside cross-linking agent.External crosslinking method uses cumbersome, and linking agent is mostly poisonous.
Aqueous polyurethane composite modification material can make up these defects existing in cross-linking modified, and the material of modification has a variety of, comprises epoxy resin and organosilicon etc.Epoxy resin has stronger rigidity and sticking power, and the performances such as gloss, stability, hardness are good, and are polyol, and with the reaction of urethane, branch point can be introduced the main chain of urethane, make it forming section reticulated structure, performance is more excellent.Adding epoxy resin can make the tensile strength of coating, water tolerance and solvent resistance obviously strengthen.
The degree of branching higher for epoxy resin, by epoxy modified aqueous urethane, is incorporated in polyurethane backbone, improves the sticking power of emulsion film, drying rate, hardness of film and water tolerance by Xu Gewen etc.With the waterborne epoxy modified polyurethane coating that its preparation over-all properties is good, be applicable to timber floor application, result of use is good.Organosilicon has unique chemical structure and extremely low surface energy because of it, effectively can improve the water tolerance of aqueous polyurethane, weathering resistance and sticking power.
Hou Menghua etc. adopt the polyether type aqueous urethane of aminosilane coupling agent modifying, have obtained the waterborne polyurethane wood coatings of excellent performance.Its specific practice is for raw material with tolylene diisocyanate, polyether glycol, dimethylol propionic acid, performed polymer is obtained by high molecular weight reactive, by this performed polymer chain extension in the amino silicane coupling agent solution of lower concentration, the aqueous emulsion of polyurethane of obtained a kind of aminosilane coupling agent modifying.This emulsion is equipped with the obtained waterborne polyurethane wood coatings of other auxiliary agent again, has excellent sticking power, water tolerance and mechanical property.The performance of the aqueous polyurethane woodenware coating of single component is also improved by other certain methods and means.
But, the range of application of water-borne wood coating technology is also very limited, the wherein antibacterial and mouldproof poor performance of most importantly wood lacquer, there is antibacterial time short, easy to change etc., especially occasion (as kitchen, toilet etc.) the easiest cooperating microorganisms of some humidity in domestic environment, causes the bacteria concentration of room air bacteria concentration and body surface to increase; In addition, current existing aqueous woodware paint can only be applied to indoor mostly, out of doors or indoor sunshine many place easily there is the phenomenons such as flavescence, cracking.
At present, the antiseptic-germicide that domestic wood lacquer uses is: organic antibacterial agent; Photocatalysis antibacterial agent, as titanium dioxide etc.; Silver ion antimicrobial agent, nano silver antimicrobials.Organic antibacterial agent persistence is poor, and microorganism easily produces resistance, and easily degraded is poisonous, does not meet environmental requirement; Photocatalysis antibacterial agent, only under the condition meeting certain UV-light, oxygen, water, just has good germ resistance, is therefore not suitable for indoor application; Good but the easy variable color of silver ions of silver ion antimicrobial agent germ resistance, not only reduces germ resistance, but also limits its application in white and light color systems; Although nano silver antimicrobials antibacterial effect broad-spectrum high efficacy, its easy oxidation discoloration, and non-refractory.The aqueous polyurethane coating again while that therefore exploitation having excellent sticking power, water tolerance and mechanical property with antifouling property has very important practical significance.
