Abstract
The invention discloses compound type coating for removing formaldehyde by combining adsorption with a chemical reaction. The coating is prepared from the raw materials of methyl methacrylate, dimerization diisocyanate, 5,5-dimethylhydantoin, calcium stearate, 3-hydroxyl butenoic acid-2-ethylene-glycol-methacrylate, polymethylacrylic acid diammonium salt, isophorone diisocyanate (IPDI), a defoaming agent, an amino monomer and a filler in parts by weight; according to the coating, the adsorption to the free formaldehyde existing in the environment is doubled through effectively combining multiple means, and an irreversible reaction occurs with the adsorption to remove the formaldehyde in a decomposing way, and meanwhile, the defect that a photoinitiator is incompatible with a resin system or the compatibility is poor is overcome, the permeation and irritation to the skin of people and livestock are reduced; the coating has the characteristics of good oil resistivity, water tolerance and weathering resistance, good coating adhesion, good toughness and excellent antiseptic property, and cannot deform and crack at low temperature, and the compatibility of all components of the coating is good.
Description
Technical field
The present invention relates to a kind of coating, particularly absorption combines with chemical reaction and removes the composite coating of formaldehyde.
Background technology
The air pollutant that room air pollution is mainly discharged by upholstery, finishing material cause, air pollutant mainly comprise: indoor total volatile organism (TVOC), radon, asbestos and microorganism etc., wherein indoor total volatile organism is mainly based on formaldehyde, benzene and dimethylbenzene, and formaldehyde is the most obvious and outstanding on the impact of HUMAN HEALTH.Since the nineties in 20th century, room air pollution health hazard becomes one of important environmental problem of national governments and public attention, and wherein Formaldehyde is particularly outstanding.Formaldehyde is a kind of volatile organic compounds, colourless, have special odor, slightly overweights air, soluble in water.Formaldehyde has material impact to HUMAN HEALTH, has strong impulse effect to eyes, respiratory tract, human body mucous membrane and skin; The symptoms such as acute poisoning can cause shedding tears, runny nose, cough, cause various respiratory tract disease; Chronic inhalation of low concentration can cause unrelenting headache, unable, insomnia etc.; Chronic skin contact can cause dermatitis, produces detrimentally affect, cause lung and liver immunologic dysfunction to the respiratory system of human body, Digestive tract and central nervous system.Formaldehyde is so serious to harm, produces and the building material product of effective degradation of formaldehyde can cause the attention of building trade.Coating is a kind of traditional material of construction, and the effect of coating is generally decoration and protection.But along with upholstery causes atmospheric pollution, require further traditional material of construction have antibacterial, the function such as purify air, although also there is air purifying paint in the market, but the formaldehyde eradicating efficacy of these air purifying paints is unsatisfactory, and need just can play air purification effect under ultraviolet irradiation.Therefore the elimination of residential building indoor formaldehyde is not suitable for, and light trigger is added in coating, consumption is difficult to owe when controlling, the problem of excessive after there is Photoinitiated reactions light trigger migration and light trigger and the disadvantage that resin system is incompatible or consistency is bad.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of absorption to combine with chemical reaction and remove the composite coating of formaldehyde, effectively combined by multiple gimmick and double to adsorb the free formaldehyde existed in environment, and there is with it irreversible reaction decomposition removal formaldehyde, solve light trigger and resin system is incompatible or consistency is bad disadvantage simultaneously, decrease the infiltration to people and animals' skin, stimulation.
Absorption of the present invention combines with chemical reaction and removes the composite coating of formaldehyde, described coating raw material comprises following component by weight: 20-40 part methyl methacrylate, 1-5 part dimerization vulcabond, 7-15 part 5,5-methylimidazole alkane diones, 3-8 part calcium stearate, 7-15 part 3-hydroxybutyric acid-2-methacrylic acid second diester, 6-12 part polymethyl acrylic acid di-ammonium salts, 8-13 part 3-isocyanic ester methylene-3,5,5-trimethylcyclohexylisocyanate, 1-4 part defoamer, 3-6 part amino monomers, 3-6 part filler;
Further, described coating raw material comprises following component by weight: 30 parts of methyl methacrylates, 3 parts of dimerization vulcabond, 12 part 5,5-methylimidazole alkane diones, 5 parts of calcium stearates, 12 parts of 3-hydroxybutyric acid-2-methacrylic acid second diester, 10 parts of polymethyl acrylic acid di-ammonium salts, 10 parts of 3-isocyanic ester methylenes-3,5,5-trimethylcyclohexylisocyanate, 3 parts of defoamers, 4 parts of amino monomers, 4 parts of fillers;
Further, described amino monomers is methacrylic acid 2-(N, N-dimethylamino) ethyl ester, methacrylic acid 2-aziridine ethyl ester or both mixtures;
Further, described defoamer aliphatic alcohol polyether defoamer;
Further, described filler is flaky mica powder, glass flake, knits one in spar, andaluzite, mullite or two or more mixture.
Beneficial effect of the present invention: absorption of the present invention combines with chemical reaction and removes the composite coating of formaldehyde, effectively combined by multiple gimmick and double to adsorb the free formaldehyde existed in environment, and there is with it irreversible reaction decomposition removal formaldehyde, solve light trigger and resin system is incompatible or consistency is bad disadvantage simultaneously, decrease the infiltration to people and animals' skin, stimulate, this coating has good oil-proofness, water tolerance, weathering resistance, coating adhesion is good, good toughness, the feature of antiseptic property excellence, and low temperature is indeformable and cracking, each component intermiscibility of coating is good, and the consumption of polymethyl acrylic acid di-ammonium salts has a great impact this formula, consumption is few, effective effect can not be played, consumption is many, macromolecular chain can be made to be entangled with, destroy Investigation of stabilized dispersion of nano, therefore, rational consumption is the stable key of guarantee system, the use of amino monomers contributes to improving sticking power, calcium stearate synergy antifoam performance.
