Description
Technical field
The present invention relates to technical field of coatings, environment-protecting polyurethane priming paint of especially a kind of ability decomposing formaldehyde and preparation method thereof.
Background technology
The detection of authoritative institutions such as China indoor environment monitoring center of upholstery association is indicated: in the house decoration at present, except volatile injurant matter (VOC), also there is serious harm in free formaldehyde to human body and environment.Free formaldehyde is a kind of higher toxicant; Be mainly derived from the tackiness agent of artificial board use, glue, furniture and the chemical fibre carpet etc. that interior decoration putty uses; Not only can cause respiratory system disease; Also can cause gastrointestinal system disorderly, seriously can cause death, confirmed as carcinogenic and teratogen by the World Health Organization.
The reinforcement of Along with people's environmental consciousness is also more and more paid attention to the environmental requirement of interior decoration; Existing coating all is the VOC content of trying every possible means to reduce coating self generally, but for indoor existing free formaldehyde, has no idea to handle.Remove formaldehyde products though occur more and more negative ions at present on the market, claim that its product can effectively decompose absorbing formaldehyde, only negative ion itself has only the germ-resistant effect of dedusting, can not remove formaldehyde.
Summary of the invention
In order to address the above problem, one of the object of the invention has been to provide a kind of environment-protecting polyurethane priming paint of ability decomposing formaldehyde; This priming paint not only content of volatile organic compound is low, in addition far below 450g/L, and really have the effect of adsorbing decomposing formaldehyde, purify air.
Two of the object of the invention has been to provide the preparation method of the environment-protecting polyurethane priming paint of said ability decomposing formaldehyde.
To achieve these goals, technical scheme of the present invention is following:

Above each raw material sum is 100% in the thinner.
Preferably, said high-solid level polyol resin is that to have that consolidating of excellent solvent release property (surface drying in 5 minutes/1 hour in do solid work) contain be 70% HMW Synolac; Preferred Changxing 3106.
Preferably, said photocatalyst opaque work piece are nano-TiO
2Photocatalyst mix by weight 1:0.5～1.5 with said high-solid level polyol resin and the photocatalyst mixture.
Preferably, said anionic additive work piece are negative ion powder with after said high-solid level polyol resin mixes by weight 1:5～10, grind with abrasive again and the negative ion mixture, the fineness of said negative ion mixture is preferably lower than 40 μ;
Preferably, said flow agent is a polyether siloxane copolymer, preferred TOGO 450.
Preferably, said anti-settling agent is that activatory gathers sour amide waxe, and is preferred: DISPALON6900HV.
Preferably, ketones solvent is mibk (being called for short MIBK).
Wherein, the preferred BYK-103 of dispersion agent, the preferred Guilin of talcum powder brilliance 1250 orders, the preferred Huaming of Zinic stearas Thailand 1846, the preferred DISPALON OX880 of skimmer, the preferred Mitsui Chemicals D-262 of TDI tripolymer, the preferred Mitsui Chemicals L-75 of TDI affixture.
Prepare the method for the environment-protecting polyurethane priming paint of said ability decomposing formaldehyde, the preparation method of said first component comprises being prepared as follows step:
A, preparation photocatalyst opaque work piece: said amount photocatalyst powder is slowly joined in the reactor drum I of said high-solid level polyol resin, is that 900～1100 rev/mins speed disperses to make in 25～35 minutes said photocatalyst opaque work piece with rotating speed;
Step B, preparation anionic additive work piece: the negative ion powder of said amount has slowly been joined in the said high-solid level polyol resin reactor drum II, is that 900～1100 rev/mins speed is disperseed to grind with horizontal mill in 25～35 minutes again and made said anionic additive work piece with rotating speed;
Step C, high-solid level polyol resin, ketones solvent and the dispersion agent of said amount being put in the reactor drum III, is that 700～900 rev/mins speed mixed 8～15 minutes with rotating speed, makes resin mixture liquor;
Step D, with in the polishing powder of said amount, the reactor drum III that talcum powder slowly joins resin mixture liquor, be that 900～1100 rev/mins speed was disperseed 25～35 minutes with rotating speed;
Step e, in the reactor drum III, add skimmer, flow agent, anti-settling agent, negative ion work piece, photocatalyst opaque work piece, and be that 500～700 rev/mins speed was mixed 15～25 minutes with rotating speed;
Step F, more than make product and get the sample test back packing of filming, make the first component;
The preparation method of said second component: earlier toluene-2,4-diisocyanate tripolymer, toluene-2,4-diisocyanate affixture and the butylacetate with said amount mixes, and is that 50～70 rev/mins speed stirred 5～15 minutes with rotating speed; Again mixture is weighed on request, packed, make the second component; The slow speed of revolution is in order in whipping process, not bring bubble into, thereby avoids the water in the bubble to react with polyisocyanic acid, influences the quality of the finished product.
Said thinner is directly by the packing of weighing of said amount.
The present invention includes first component, second component and thinner, the ratio of weight and number of said first component and second component is 2:1; Wherein, said first component comprises high-solid level polyol resin, esters solvent, dispersion agent, talcum powder, skimmer, anionic additive work piece, photocatalyst opaque work piece, flow agent and anti-settling agent; Admittedly contain 70% HMW Synolac among the present invention, have good solvent release property and drying property; Nano-TiO
2Photocatalyst more is prone to disperse with after polyol resin mixes by a certain percentage.Because free formaldehyde mainly is to be produced by tackiness agents such as the glue in building materials volatilization institute, it is long to have time of releasing, the characteristics that removing is difficult; And general anionic additive has the dispersive of being difficult for characteristics in the oiliness polyurethane coating; The elite negative ion opaque of the present invention work piece grind to form slurry after mixing with certain proportion with the high-solid level Synolac is first again, disperse so that more be prone to; More be evenly distributed in the coating; Make it have ageing length, the characteristic that adsorption effect is good, thus the formaldehyde in the coating lower floor building materials is had better adsorption.
Behind the anionic additive absorbing formaldehyde in the priming paint of the present invention, the formaldehyde that is adsorbed migrates to coating surface, with nano-TiO
2Photocatalyst decomposes through photosynthesis generation redox; And general nano-TiO
2Outward appearance is a white, and need mix just earlier with the high-solid level Synolac can not influence the coating FINAL APPEARANCE.Through above reaction, free formaldehyde finally becomes CO
2And H
2O discharges.
In brief, the ultimate principle of aldehyde removing type polyurethane primer is through anionic additive free formaldehyde to be adsorbed, and utilizes the solvent release of resin, makes free formaldehyde migrate to coating surface, carries out redox through photocatalyst again and decomposes, and finally becomes CO
2And H
2O discharges, thereby reaches the effect that purifies formaldehyde.
Negative ion absorption principle among the present invention:
Photocatalyst decomposition principle among the present invention:
Airborne H

OH+HCHO (formaldehyde) → H
2O+CO
2
In a word; The present invention utilizes the synergism of anionic additive and photocatalyst opaque work piece through to the different Grafting Structure of resin and to the choosing of deleting of the intermiscibility of lipid, ketones solvent, not only makes this priming paint keep conventional urethane to coat with lacquer characteristics such as the application property that is had is good, water-tolerant, hardness height; And have characteristics of high-solid lower-viscosity; Guarantee that VOC very low in construction process discharges, have low ring dirt property, free TDI content≤0.5%; Especially can decomposing formaldehyde, and purifying formaldehyde efficient>=75%.
In addition, other auxiliary agents, the filler of the choosing of deleting in the coating improve the stability in storage and the application property of coating.
