Description
Technical field:
The present invention relates to a kind of production technology causing the soybean protein formaldehyde scavenger of Formaldehyde Pollution Treatment for indoor decoration pollution.
Background technology:
1, the harm of formaldehyde, source:
In recent years, along with the raising of living standards of the people, the requirement of people to interior decoration standard is also more and more higher, and home decoration is modernization increasingly, but the room air chemical contamination problem caused due to material and finishing is following.It is healthy that these chemicals have had a strong impact on resident, caused the great attention of countries in the world and domestic relevant department.In numerous pollution sources, formaldehyde to measure large, strong toxicity, absorption is strong, scope is wide, has been classified as No.1 pollutant.
Formaldehyde is a kind of volatile organic matter with larger toxicity.(chemical molecular formula HCHO, molecular weight: 30.03 are a kind of colourless, have the gas of intense stimulus smell.Soluble in water, alcohol ether.Formaldehyde is gaseous state at normal temperatures, usually occurs as an aqueous solution.Its aqueous solution of 40% is called formalin, and this solution boiling point is 19 DEG C.Therefore when room temperature highly volatile, along with the rising evaporation rate of temperature is accelerated.
Formaldehyde is more highly toxic material, and being defined as carcinogenic and cause deformed material by the World Health Organization, is generally acknowledged allergen, is also one of potential strong mutagen.Research shows: formaldehyde has strong carcinogenic and tumor promotion.Lot of documents is recorded, and the impact of formaldehyde on health is mainly manifested in the aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction.When its concentration reaches 0.06-0.07mg/m3 in every cubic metres of air, will there is slight asthma in children.When formaldehyde content in indoor air is 0.1mg/m3, just there are peculiar smell and sense of discomfort; When reaching 0.5mg/m3, can eyes be stimulated, cause and shed tears; Reach 0.6mg/m3, throat discomfort or pain can be caused.When concentration is higher, can cause nausea vomiting, coughs uncomfortable in chest, even pulmonary edema of panting; When reaching 30mg/m3, meeting causing death immediately.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma, colon cancer, brain tumor, paramenia, nuclear gene mutation, commissure and DNA and protein commissure and suppress the reparation of DNA damage, pregnancy syndrome, cause neonatal chromosome disorder, leukaemia in DNA single chain, cause teenager's memory and intelligence to decline.In all contactees, children and pregnant woman's PARA FORMALDEHYDE PRILLS(91,95) particularly responsive, harm is also just larger, because caused by the pollution of finishing and furniture, its release period reaches 3-15, and heat and wet will evaporate from material deep layer, serious environment pollution, has become insoluble global problem.
Investigation finds, causes the main path of Formaldehyde Pollution of Indoor Air to be a large amount of ornament materials of using of household and furniture etc., mainly comprises the artificial boards such as indoor decoration glued board, core-board, particieboard.Be master owing to producing adhesive that decorative panel uses at present mainly with Lauxite, therefore residual in sheet material formaldehyde components can discharge gradually in air, become the main source that in indoor gas, formaldehyde gas pollutes, and the formaldehyde gas discharged also can gather gradually in wall, floor, even toy for children, larger harm is caused to human body especially teenager.In addition, other kinds ornament materials also contains formaldehyde components as wall paper, wallpaper, chemical fibre carpet, paint and coating etc. thus causes indoor formaldehyde gas content to increase.And artificial floor, furniture employ glue inferior also can produce a large amount of formaldehyde emissions as employed underproof sheet material or adhesives.Be noted that formaldehyde especially also from cosmetics, cleaning agent, pesticide, disinfectant, anticorrisive agent, printing, ink, paper etc., even also contain a large amount of formaldehyde in some clothing.
Above-mentioned analysis shows: formaldehyde has the features such as multipath, disguise, characteristic of concentration in the pollution of indoor.It distributes approach and includes building materials, ornament materials and articles for daily use etc., and simultaneously because the slow releasing characteristic of formaldehyde is toward being not easily therefore easily perceived by humans, and itself can not decompose very soon, and this just makes the extent of injury of formaldehyde even more serious compared with other polluters.So it is extremely important to invent a kind of medicament efficiently thoroughly removing formaldehyde.
2, prior art:
Current formaldehyde eliminating agent (formaldehyde catching agent) can be divided into 4 classes substantially:
The first kind is sealer, if application number is blocking absorbent of formaldehyde of 01138098.5 invention and preparation method thereof and using method, is mainly made up of chitosan, acetic acid and water, forms transparent membrane sealed formaldehyde.
Equations of The Second Kind is the oxidant of energy oxidation of formaldehyde, and the formaldehyde scavenger being 200510090754.1 inventions as application number is with the mixed solution of sodium acid carbonate, hydrogen peroxide and water composition, plays by oxidation free formaldehyde molecule the effect eliminating formaldehyde pollution;
3rd class is the derivative of ammonia, as application number be 02100765.9 invention utilize the derivative of ammonia for raw material, carry out reaction in neutral conditions with urea and manufacture formaldehyde catching and remove formaldehyde.
4th class is amino acids, if application number is a kind of amino acid type formol release agent of 200610017363.1 inventions and preparation method thereof, generates methylol acid remove formaldehyde by amino acid and formolite reaction.
From principle, sealer has blocked the source of Form aldehyde release, thoroughly should be able to eliminate the pollution channel of formaldehyde, it is a kind of relatively good way, but, in actual use, because furniture is inevitably worn in daily life, the sealer smeared originally after after a while will lose original effect.And use the method such as formaldehyde eliminating agent, agent for capturing to there is the problem of eradicating efficacy, although to a certain extent can decreasing pollution, but the impact of the factors such as the contaminated degree of the pollution due to indoor environment, temperature, air circulation degree, eliminative reaction is often difficult to carry out thoroughly, therefore being also difficult to reach the effect of desirable elimination formaldehyde.What also should remind consumer alert especially here is that some formaldehyde eliminating agent itself is with low quality, and not only eradicating efficacy is not obvious, does not even have the effect eliminating formaldehyde, also likely causes the secondary pollution of room air on the contrary.
3, summary of the invention
The present invention take soybean protein as primary raw material, adopts biological enzyme, oxidation, technology for hydrolyzing, and adds complex enzyme formulation and make a kind of transparent, colourless, tasteless, nontoxic soybean protein formaldehyde scavenger through special process.During use, adopt potent barrier formulations, make its through material deep layer, utilize infiltration neutralization reaction principle, react with the formaldehyde in material, thoroughly eradicate formaldehyde, generate a kind of colourless nontoxic, Undec material after reaction, can not secondary pollution be caused.Spary just can take effect after 20 minutes, and hour better effects if after 24, the clearance rate of PARA FORMALDEHYDE PRILLS(91,95) is up to more than 90%.
