Description

A kind of wallpaper is special except formaldehyde agent
Technical field
The present invention relates to a kind of wallpaper special except formaldehyde agent.
Background technology
Wallpaper is the important materials of interior decoration.The ratio that domestic use wallpaper is decorated as wall has significantly every year grows up.Wallpaper is attractive in appearance has again an individual character, and other building material cost is also lower relatively, so wallpaper popularity rate in this year more and more higher (the about 15%-20% of current civilian household's wallpaper popularity rate left and right).Wallpaper is to be posted in indoor four sides wall, so be the product that occupies maximum area in all art work.Our company is engaged in wallpaper manufacturing industry and exceedes 30 years, wishes that for a long time wallpaper, except attractive in appearance and individual character, can increase more function value always.
Current research shows that formaldehyde has become first kind carcinogen.Formaldehyde causes the mankind's nasopharyngeal carcinoma, CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer, and can cause leukaemia.According to state compulsory standard, to close the doors and windows after 1 hour, in every cubic metre of room air, burst size of methanal must not be greater than 0.08 milligram; As reaching 0.1-2.0 milligram, 50% normal person can smell foul smell; Reach 2.0-5.0 milligram, eyes, tracheae will be subject to intense stimulus, occur sneezing, the symptom such as cough; Reach more than 10 milligrams expiratory dyspnea; Reach more than 50 milligrams, can cause the critical illness such as pneumonia, even causing dead formaldehyde is a kind of extremely strong bactericide, is widely used in industrial production.Being the raw material of manufacturing synthetic resin, paint, plastics and staple fibre, is the important source material that wood-based panel industry is manufactured urea-formaldehyde resin adhesive, melamine resin adehsive and phenolic resin glue.People's the place such as the new home and office all will be carried out interior decoration and be bought furniture, due to finishing and Furniture manufacture to use a large amount of artificial boards (as glued board, lumber core, MDF, particieboard, consolidated floor and compoiste wood floor etc.), need the high formaldehyde of a large amount of use toxicity be the adhesive that raw material is manufactured and produce wood-based plate, because the formaldehyde release period in adhesive is very long, generally reach 15 years, cause formaldehyde to become the major pollutants in room air.Formaldehyde is more highly toxic material, preferentially controls formaldehyde on list be in second at China's toxic chemical.Formaldehyde is defined as carcinogenic and causes deformed material by the World Health Organization, is generally acknowledged allergen, is also one of potential strong mutagen.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma, colon cancer, brain tumor, paramenia, nuclear gene mutation, in DNA single chain commissure and DNA and protein commissure and suppress DNA damage reparation, pregnancy syndrome, cause neonatal chromosome disorder, leukaemia, cause teenager's memory and intelligence decline.In all contactees, children and pregnant woman's PARA FORMALDEHYDE PRILLS(91,95) are particularly responsive, and harm is also just larger.The more Gao Shike vomiting that causes nausea of concentration, coughs uncomfortable in chest, asthma, pulmonary edema, causing death even immediately.
The formaldehyde mode of removing of commonly using on the market at present has " bamboo Charcoal Adsorption " method.Bamboo charcoal (active carbon) is the microcellular structure that has a lot of sizes to calculate with micron, and PARA FORMALDEHYDE PRILLS(91,95) has adsorption capacity, before bamboo charcoal absorption is saturated, truly has effect of eliminating formaldehyde.But bamboo charcoal does not have the function of decomposing formaldehyde, formaldehyde still likely discharges the in the situation that of variation in certain indoor temperature, humidity again, pollutes indoor.So the function of bamboo Charcoal Adsorption formaldehyde is unstable, incomplete method.In addition bamboo charcoal don't work which kind of mode be placed in indoor, really hinder attractive in appearance, common people can not like use.
There is in addition " green plants absorbing formaldehyde " method.Also be that common people think simple effective method." bracketplant " of extensively being praised highly is at present the most effective plant.According to relevant expert's research, bracketplant is processed the blade formaldehyde that can absorb 0.15 milligram per hour of the approximately every square meter of average speed of formaldehyde.But blade area less than 0.1 square meter of a strain bracketplant, only can absorb 0.36 milligram of formaldehyde 24 hours every days.If 100 square meter indoor walls high 3 meters (totally 300 cubic metres of volumes) concentration of formaldehyde is 0.5 milligram/cubic metre, always have 150 milligrams of formaldehyde.If drop to IAQ standard GB/T188883-2002 (0.1 milligram/cubic metre), just need to remove 120 milligrams of formaldehyde.That strain bracketplant need to just can remove with 333 days complete, or 100 square meters indoor needs to place 333 strain bracketplant, indoor peace and quiet of guarantee.Some plant is to have the function of formaldehyde of removing, and their can generate formaldehyde and specific chemical reaction amino acid (as serine) or directly become carbonic acid and carbon dioxide, if but indoorly pile green potted plant, be probably also unpractical.So " green plants absorbing formaldehyde " method is only a kind of poor efficiency method of comforting the popular feeling.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, wallpaper is special except formaldehyde agent thoroughly to the invention provides a kind of removing formaldehyde.
The technical solution adopted in the present invention is: a kind of wallpaper is special except formaldehyde agent, it is characterized in that: it is by following composition: bleeding agent, main reaction agent and another name for oil form, and described main reaction agent is nano titanium oxide, and the particle diameter of titanium dioxide is 5-20nm.
Compared with prior art, the invention has the beneficial effects as follows: utilize nano titanium oxide absorption, catalytic decomposition formaldehyde to become water and carbon dioxide, thoroughly remove formaldehyde, later stage can reversal reaction, permanently effective again, this scavenger water-based formula, dry run is safety and environmental protection relatively.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
In order more clearly to understand technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is further described.
A kind of wallpaper of the present invention is special except formaldehyde agent, it is characterized in that: it is by following composition: bleeding agent, main reaction agent and another name for oil form, and described main reaction agent is nano titanium oxide, and the particle diameter of titanium dioxide is 5-20nm.
In conjunction with Fig. 1, nano titanium oxide, because its surface area is very large, can adsorb formaldehyde on surface and under ultraviolet effect, make formaldehyde be decomposed by airborne dioxygen oxidation.Direct product after oxidation of formaldehyde is formic acid, and can further be oxidized to water and carbon dioxide.This is exactly so-called process of administering.Ultraviolet effect is to generate ozone, and the oxidisability of ozone will be better than oxygen greatly, and it is fast a lot of that reaction speed is wanted, the effect of Here it is ultra violet lamp.
Airborne formaldehyde and ozone also can decompose, still, and because concentration of formaldehyde is very low, ozone concentration is also very low, so two gas molecule collisions the chance reacting are just smaller, the absorption formaldehyde that has nano titanium oxide high surface area, reaction is manyfold soon.
Can be by it when use the gravure printing wheel of 60mesh-100mesh for " the stamp link " in wallpaper production procedure, be transferred on wallpaper except formaldehyde agent special photocatalyst wallpaper, the topped use amount of 100% area need reach 25g/m 2above, then within 40 seconds, just can guarantee the solid sclerosis of film through 210 DEG C of oven dryings, be difficult for scratch or come off.
Also can use as follows: wallpaper is special except formaldehyde agent: be water prescription, also can directly brush on wall, natural drying long-term effect exists too.But the slightly poor scratch generation scratch that is easier to of natural drying hardness of film.If at the indoor electric heater that adds, keep 35 DEG C of room temperatures to continue 24 hours after brushing, can improve hardness of film.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
