Abstract

The invention relates to indoor wall environmental-friendly coating, and belongs to the technical field of energy conservation and environment protection. The coating comprises SiO2 aerogel particles and TiO2 particles, wherein the mass of the SiO2 aerogel particles is 1-10% of the total mass of the coating, and the mass of the TiO2 particles is 1-10% of the total mass of the coating. Experiment testing results of adsorption/photocatalytic degradation of formaldehyde show that: when the coating comprises 2.5-5.0% of high-adsorptivity particles with photocatalytic activity, and after adsorption/photocatalytic degradation is performed for 5-6 h, the formaldehyde concentration in the system decreases from 0.39 mg/m3 to final 0.04-0.05 mg/m3, and the adsorption/photocatalytic degradation rate reaches 79.49-89.74%.

Description

Indoor wall environmental protection coating material
Technical field
The present invention relates to indoor wall environmental protection coating material, belong to energy-conserving and environment-protective technical field.
Background technology
Along with the raising of people's living standard and a large amount of uses of building and ornament materials, indoor air environment to the health problem of human body progressively pay attention to by increasing people, therefore environment protection type functional building coating also more and more receives publicity.Such as, invented a kind of light catalyzed coating with photocatalytic activity and absorption property in patent ZL 02810799.3, wherein sorbent material is based on the silicate of magnesium or calcium or diatomite, and photocatalyst is then with TiO 2or ZnO is main, its coating is originally as solvent reducible coatings.Patent ZL 200510011793.8 provides a kind of light catalyzed coating modified by nitrogen dopen Nano titanium dioxide, and what introduce in this patent is by the nano-TiO of doping nitrogen 2join in water-borne coatings, make it have photocatalysis.Patent CN1962776A provides a kind of composite air purifying paint, it with water, water-based emulsion for main component, by adding negative ion slurry, antiseptic-germicide, plant fragrance agent, can sustained release negative ion and there is higher clearance to obnoxious flavoures such as the formaldehyde in air, benzene, ammonia.At present, air purifying paint is by TiO in coating mostly 2deng photocatalytic activity particle photocatalytic Degradation or negative ion effect or utilize the sorbent materials such as diatomite to reach the effect of purifying air.But it is reported, photocatalytic particle while organic pollutant, often also can have Degradation to coating itself in photocatalytic degradation air, thus causes paint aging phenomenon obvious; On the other hand, in coating, separately add sorbent particles and photocatalytic particle, often because the absorption of sorbent particles and photocatalytic particle is saturated and the photocatalytic degradation limit and make air purification effect not obvious.
Summary of the invention
The present invention, by improving coating composition, makes coating have environment-friendly function.
The invention provides indoor wall environmental protection coating material, environmental protection coating material comprises SiO 2aerogel particles, dilute hydrochloric acid, TiO 2particle, sodium sulphite, SiO 2aerogel particles accounts for 1 ~ 10%, TiO of coating total mass 2particle accounts for 1 ~ 10% of coating total mass.
SiO 2aerogel particles is a kind of lightweight mesoporous material, has high pore volume and high-specific surface area feature, has efficient absorption property.By SiO 2the high efficiency of additive capability of aerogel particles and photocatalyst TiO 2the photocatalysis performance of particle combines, and will play SiO simultaneously 2the high efficiency of additive capability of aerogel particles and photocatalyst TiO 2the photocatalysis performance of particle.
SiO of the present invention 2aerogel particles preferably accounts for 1 ~ 5%, TiO of coating total mass 2particle preferably accounts for 1 ~ 5% of coating total mass.
SiO of the present invention 2aerogel particles more preferably accounts for 2 ~ 3%, TiO of coating total mass 2particle more preferably accounts for 2 ~ 3% of coating total mass.
Environmental protection coating material of the present invention by mass percentage, is preferably made up of following component:
Emulsion 20 ~ 50%
Ethanol 20 ~ 40%
Propylene glycol 1 ~ 2%
SiO 2aerogel particles 1 ~ 10%
TiO 2particle 1 ~ 10%
Auxiliary agent 1 ~ 2%
Dilute hydrochloric acid 1 ~ 2%
Sodium sulphite 1 ~ 10%
Water surplus.
Emulsion of the present invention is preferably ACRYLIC EMULSION or fluorine carbon emulsion, and described ACRYLIC EMULSION is benzene emulsion, organosilicon crylic acid latex, pure-acrylic emulsion or acrylate and vinyl acetate emulsion.
Auxiliary agent of the present invention comprises dispersion agent, film coalescence aid, defoamer, flow agent, wetting agent, thickening material.
Beneficial effect of the present invention is have the aerogel adsorber particles of high efficiency of additive capability containing a certain amount of and have the TiO of photocatalysis performance in coating 2photocatalyst particles.The present invention with the addition of the aerogel particles with high efficiency of additive capability and the photocatalytic particle with photocatalytic Degradation in coating simultaneously, the efficient adsorption effect of aerogel can promote Photocatalytic Degradation Process, and photocatalytic degradation can promote that aerogel is to the further absorption of toxic gas further, absorption/photocatalytic degradation acts synergistically and mutually promotes, more effectively can eliminate the obnoxious flavour in air, compared with current air purifying paint, air purification effect will be more efficient and permanent.The experimental results of absorption/formaldehyde degradation by photocatalytic oxidation process shows, when containing high absorbability and the photocatalytic activity particle of 2.5 ~ 5.0% in coating, after absorption/photocatalytic degradation 5 ~ 6h, the concentration of formaldehyde in system is from 0.39mg/m 3be reduced to 0.04 final ~ 0.05mg/m 3, absorption/photocatalytic activity reaches 79.49 ~ 89.74%.
Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.
embodiment 1
Indoor wall environmental protection coating material, described environmental protection coating material by mass percentage, is made up of following component:
