Description
Technical field
The present invention relates to technical field of coatings, be specifically related to the preparation method of a kind of formaldehyde absorbing Environmental Protective Water-paint.
Background technology
Coating is that one can firmly cover at body surface, rises and protects, decorates, indicates and the chemical mixture of other specific uses
Coating.China's more authoritative " coating process " book of coating circle is defined such that " coating is a kind of material, this material
Material can be coated in object surface by different construction technologies, and formation adheres to firmly, has some strength, continuous print solid film.
The film common name film so formed, also known as paint film or coating." belonging to organic chemical industry's macromolecular material, the film formed belongs to high
Molecular compound type.According to the classification of the chemical products that the modern times pass through, coating belongs to fine chemical product.Modern coating is just
Progressively becoming a polyfunctional engineering material of class, be an important industry in chemical industry.
Along with improving constantly of people's living standard, finishing when purchasing or build the new home, all can be selected.Interior wall water emulsion coating is
The indispensable material of finishing, also can be used as ceiling coating, plays decoration and protection inner wall surface and the effect of ceiling.Along with people's ring
Protecting the enhancing of consciousness, the requirement to the interior wall water emulsion coating of finishing is more and more higher, the polyethylene that burst size of methanal is higher
Alcohol formal class coating is the most gradually eliminated, various anion releasings, low VOC (VOC) environment-friendly type in
It is more and more that wall coating uses, and how to develop the problem that environment-friendly coating becomes people's growing interest.But in prior art
Interior wall water emulsion coating itself be the effect not having and removing the toxic gas such as formaldehyde in indoor air.
It is known that indoor environmental pollution is mainly with the most serious after fitting up of new residence, after fitting up of new residence, modal chemical contamination has
Poisonous gas includes formaldehyde, benzene homologues, ammonia, radon gas and volatile organic matter etc., this five kinds of toxic gas and harmful substance quilt
" the 5 big stealthy killer " being referred to as in house fitting.Wherein formaldehyde is the most serious to the harm of human body, is determined by World Health Organization (WHO)
For carcinogenic and cause deformed material, the allergen being well recognized as, also it is one of potential strong mutagen, has been listed in China
The detection project that building decoration engineering is enforced.
Formaldehyde the impact of health is mainly manifested in heterosmia, stimulation, allergy, abnormal pulmonary function, abnormal liver function and
The aspects such as immunologic dysfunction.Long Term Contact low dosage formaldehyde can cause chronic respiratory tract disease, also can cause time serious nasopharyngeal carcinoma,
Colon cancer, cerebroma, menoxenia and nuclear gene mutation, also can cause commissure and DNA and protein in DNA strand
Commissure and the suppression reparation of DNA damage, pregnancy syndrome, neonatal chromosome disorder, leukemia etc., also can cause blue or green few
Year memory and intelligence decline.In all contactees, child and anemia of pregnant woman's PARA FORMALDEHYDE PRILLS(91,95) are particularly sensitive, endanger the biggest.According to phase
Pass statistics show: the mankind have 70% disease relevant with indoor environment, China has 130,000 people to die from indoor pollution every year,
The child leukaemic of more than 90% lives in new clothes are repaired the house 1 year ill.
At present, the method for existing removal formaldehyde mainly has following several: ventilation method, activated carbon adsorption, with water, vinegar, black tea
Soaked formaldehyde of removing, photocatalytic method, the fruit formaldehyde adsorption such as Fructus Citri tangerinae, Fructus Ananadis comosi, plant absorption formaldehyde, air purifier removes first
Aldehyde.But, ventilation method, activated carbon adsorption, with water, vinegar, the soaked formaldehyde of removing of black tea, the fruit such as Fructus Citri tangerinae, Fructus Ananadis comosi adsorbs
The methods such as formaldehyde substantially do not reach the requirement removing formaldehyde, and absorbability is extremely limited；Under comparing, photocatalytic method has
Certain sterilization, deodorization, mildew-resistant, anti-fouling and self-cleaning, air purification function.Although said method can alleviate dirt to a certain extent
Dye degree, but it is all the remedial measure after finishing, it is not meant to be inherently eliminated room air pollution.
In recent years, lot of domestic and international scientific research institution is all being devoted to develop what the toxic gas such as a kind of efficient purifying formaldehyde polluted
Material.As the Chinese patent of Publication No. CN101560339A discloses a kind of air purification environment-friendly coating, the composition of this coating
And percentage by weight is: water 35%, Pulvis Talci 25%, Kaolin 20%, multifunctional assistant 2.5%, thickening agent 1.5%,
Compound levelling agent 1.5%, defoamer 1.5%, wetting agent 1.5%, antibacterial 5%, plant fragrance agent 0.5%, coalescents
2.0%, preservative 1.5%, antifungus agent 1.5%, dispersant 0.5%, brightening agent 0.5%；Above-mentioned this air cleaning and environment-friendly is coated with
Expect, for removing formaldehyde, there is certain effect, but, the purification efficiency of the toxic gas such as its formaldehyde is the highest, and clean-up effect is lasting
Property is the highest, and this air purification environment-friendly coating cannot produce anion, and antibiotic rate is about 90%, antibacterial and mouldproof effect
Poor, the most complex due to its component again, add cost.The Chinese patent of Publication No. CN105174859A is open
A kind of based on kieselguhr micropowder except formaldehyde in indoor air, abnormal flavour interior wall coating, it is characterised in that in terms of parts by weight
Comprise following components: kieselguhr micropowder 30～40 parts；Nano titanium dioxide/diatomite composite photocatalytic material 10～20 parts；
Calcined kaolin 11～21 parts；Ground calcium carbonate 5～15 parts；Precipitated calcium carbonate 2～8 parts；Cellulose ether 0.5～2 parts；Wood
Matter cellulose 1～3 parts；Redispersable latex powder 1～5 parts；White cement 7～17 parts.Actual application finds, this coating first
Aldehyde purification efficiency reaches 86.8～88.2%, and purifying formaldehyde effect persistency reaches 72.8～74.0%；Toluene purification efficiency reaches
52.1～54.2%, toluene clean-up effect persistency reaches 34.8～36.0%, although has and necessarily improves, but modern society people couple
The requirement of quality of the life is higher, therefore has higher requirement more efficient, more environmentally friendly coating.
