Dispersion agent described in the present invention is Henkel KGaA 5040 dispersion agents, has good thermotolerance, mutual solubility, efficient height, and stable viscosity prevents the coating precipitation, coagulates wadding.Keep good, nontoxic, the no burn into of glossiness not have special odor.
Aldehydes removal emulsion described in the present invention is LG-DOW chemical industry 3030 emulsions.Have superpower aldehydes removal effect, can effectively decompose formaldehyde in the coating.
Bamboo charcoal powder described in the present invention is a specification: (1000～4000 order) is many as coating class Industrial products raw material.Because the specific surface area of bamboo charcoal increases by geometric progression after the super-fine processing, specific functions such as the absorption of bamboo charcoal, decomposition are also strengthened synchronously.
Anti-formaldehyde principle of the present invention is in formulating of recipe, and the method for utilizing physical adsorption to combine with decomposition is removed formaldehyde.Adopt clean aldehyde emulsion, bamboo charcoal powder, nano-TiO
2Photocatalyst, etc. three kinds of aldehydes removal materials comprehensively use, reach the purpose of the anti-formaldehyde of high-efficient and lasting.
One, the clean aldehyde mechanism of emulsion:
The selection PARA FORMALDEHYDE PRILLS(91,95) has adsorption and can carry out formulating of recipe with the emulsion of formaldehyde generation irreversible chemical reaction.The surface of formaldehyde reaction emulsion or inner residual a large amount of active groups (as amino, carboxyl, epoxy group(ing) etc., all can with formaldehyde generation irreversible chemical reaction).Formaldehyde reaction emulsion and ordinary emulsion all have the ability of certain elimination formaldehyde in indoor air.The mechanism that ordinary emulsion is eliminated formaldehyde is the adsorption of emulsion film PARA FORMALDEHYDE PRILLS(91,95), and this effect is a reversible; And reaction victory emulsion has the elimination formaldehyde ability more much better than than ordinary emulsion.
Two, the anti-formaldehyde mechanism of bamboo charcoal powder:
There is microvoid structure in bamboo charcoal, has greater porosity (macrovoid, mesopore and micropore) and high-specific surface area, and obnoxious flavoures such as PARA FORMALDEHYDE PRILLS(91,95), volatile solvent have good physical absorption effect, and the application in coating is more and more.Certainly, physisorption has certain limitation, mainly shows two aspects: the one, there is saturation ratio, and the 2nd, adsorptive power is relevant with temperature.Therefore, removing obnoxious flavoures such as formaldehyde in the room air and volatile solvent by physical adsorption, is practical, effective scheme to a certain extent.
Three, TiO
