Description
Technical field
The present invention relates to a kind of environmental protection and remove wood lacquer of formaldehyde and preparation method thereof, belong to paint industry.
Background technology
At present, along with socioeconomic development, the demand of people to living facilities improves constantly, and the environmental issue in family's fitment process becomes increasingly conspicuous, and causes showing great attention to of the whole society.People improve while quality of the life beautifying home, and in some underproof fitment material for families, the use of objectionable impurities is constantly endangering the healthy of oneself and household.Formaldehyde is in second on the indoor hazard substance control list of China, is called as stealthy killer.Current, room air is commonplace by the problem of formaldehyde pollution, and these formaldehyde mainly come from various chemical building material and the furniture of interior decoration.Because formaldehyde resin is used to various material of construction, comprise glued board, woollen blanket, lagging material, timber products, floor, tobacco, finishing and finishing material, and because formaldehyde resin can slowly continue to release formaldehyde, therefore formaldehyde becomes one of common room air pollution.Formaldehyde generally slowly can disengage from source, and the formaldehyde amount that fresh product disengages within the initial several months is the highest, and after for some time, the formaldehyde amount of disengaging just can reduce gradually.When concentration of formaldehyde reaches 0.06-0.07mg/m3 in every cubic metres of air, will there is slight asthma in children; When formaldehyde in indoor air reaches 0.1mg/m3, just there are peculiar smell and sense of discomfort; When formaldehyde reaches 0.5mg/m3, can eyes be stimulated, cause and shed tears; When formaldehyde reaches 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 formaldehyde reaches 30mg/m3, meeting causing death immediately.Formaldehyde is to skin and the irritant effect of mucous membrane, and the skin of contacted formaldehyde may occur allergic phenomena, and severe patient even can cause hepatitis, pneumonia and kidney damage.If the aerial concentration of formaldehyde, more than 0.1mg/m, can cause the injury of eyes and mucosa cells.In vivo, formaldehyde may cause protein irreversibly with DNA bond.Experimentation on animals display is exposed in heavy dose of formaldehyde and nose and the carcinogenic probability of throat can be made to increase.But formaldehyde content concentration is enough to produce carinogenicity in most building.
But the urea-formaldehyde adhesive contained in these materials and furniture is unstable, and easily cracking regenerates formaldehyde and urea gradually, and the Form aldehyde release phase is very long, generally take more than 3-5 years even until material all aging after, just can reach harmless degree.According to the investigation of Chinese Consumers' Association, in newly-decorated house, formaldehyde generally exceeds standard and reaches 4-6 doubly, and what have even exceeds standard more than ten times.Great threat the health of people, and what have even causes very serious consequence, endangers more so women's (can cause gestation extremely) and children's (can cause leukemia).Some administering method in the market have many deficiencies, are not shortly (as each quasi-instrument aldehydes removal, only can maintain 3-5 days working lipe; Some de-aldehyde agent of spraying, when there is the formaldehyde of new release again, it is just helpless), regulation effect is poor, in addition as gac, bamboo charcoal etc., because contact area is too little, is difficult to reach desired effect.
Summary of the invention
The invention provides a kind of environmental protection except wood lacquer and preparation method thereof of formaldehyde solves the problems such as formaldehyde content is high, emissioning time is long, harm humans is healthy in existing wood lacquer.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of environmental protection is except the wood lacquer of formaldehyde, according to parts by weight, comprise ACRYLIC EMULSION 550-650 part, flow agent 8-12 part, defoamer 4-7 part, dipropylene 30-40 part, dipropylene glycol methyl ether 40-50 part, linking agent 4-6 part, aldehydes removal element NNS2-3 part, wetting agent 1-1.5 part, butyl glycol ether 6-10 part, thickening material 3-4 part, wax emulsion 15-25 part and water 250-300 part.
Further, a preferred embodiment of the present invention is: according to parts by weight, comprises ACRYLIC EMULSION 600 parts, flow agent 10 parts, defoamer 6 parts, dipropylene 35 parts, dipropylene glycol methyl ether 45 parts, linking agent 5 parts, aldehydes removal element NNS2 part, wetting agent 1.3 parts, butyl glycol ether 10 parts, thickening material 3.1 parts, wax emulsion 20 parts and 270 parts, water.
Further, a preferred embodiment of the present invention is: described emulsion is ACRYLIC EMULSION.The emulsion that the present invention adopts can be the emulsion of all adaptations and water-soluble wood lacquer.Preferred ACRYLIC EMULSION.ACRYLIC EMULSION can provide good film forming properties, not containing APEO in ACRYLIC EMULSION, also not containing formaldehyde.The effective fragment of macromolecular chain of ACRYLIC EMULSION can carry out irreversible crosslinking reaction with the formaldehyde in air, after formaldehyde is caught by the effective fragment of the macromolecular chain of ACRYLIC EMULSION, generation-N-CH2-OH is reacted with the parahelium group-NH in the effective fragment of macromolecular chain, then slough an one's share of expenses for a joint undertaking H2O between two adjacent-N-CH2-OH groups, formaldehyde is fixed in the effective fragment of macromolecular chain of ACRYLIC EMULSION.The effect that can effectively improve except formaldehyde and the activity improving aldehydes removal element NNS is combined with aldehydes removal element NNS.
Further, a preferred embodiment of the present invention is: described water is deionized water.
Environmental protection of the present invention, except the preparation method of the wood lacquer of the wood lacquer of formaldehyde, comprises the following steps:
(1) by the defoamer of emulsion, flow agent and 40-50% 180-250 turn/min under stir,
(2) rotating speed is dropped to 100-150 and turn/min, then add the water of dipropylene, dipropylene glycol methyl ether, linking agent, aldehydes removal element NNS, wetting agent, remaining defoamer and 85-90%, stir;
