Description
Technical field
The present invention relates to technical field of chemical paint, particularly relate to a kind of aqueous woodware paint of closed methanal.
Background technology
At present, in house decoration, the house ornamentation that the objectionable impurities such as formaldehyde, benzene homologues, TVOC brought due to various finishing material causes pollutes and the exceeding standard of objectionable impurities in room air, seriously disturbs the orthobiosis of people.Cause room air pollution substantially to have two sources, one is finishing or the topcoating of furniture, the solvent usually using organic solvent as paint, containing the pollution substance that benzene homologues etc. is harmful in these solvents; Another is the tackiness agent of bonding various material, is such as present in the tackiness agent in the sheet material such as wood-based plate, Homogenholz, wherein containing a large amount of formaldehyde.Known, formaldehyde is the principal pollutant that China newly fits up in family and plate fitment, and children and elderly population and pregnant woman are that excessive risk is injured crowd.On June 5th, 2004, formaldehyde is promoted to a class carcinogenic substance by the World Health Organization.Formaldehyde is the stealthy killer of household, easily causes chronic respiratory tract disease, allotriosmia, stimulation allergy, liver, abnormal pulmonary function, immunologic dysfunction, can leukemogenesis, nasal cavity, oral cavity, nasopharynx.Along with people's environmental consciousness progressively improves, country puts into effect in succession " indoor decorating and refurnishing materials, limits of harmful substances standard " increasing such as (GB18580 ~ 18589-2001), " limitation of aldehyde used for textiles " hazardous and noxious substances limitation, within 2006, the Chinese indoor air chemical pollution council issues indoor environment warning: to Beijing, Qingdao etc. 6 big city indoor environmental pollution detect, on average about have 7 one-tenth formaldehydes, China is about newly-increased leukaemic more than 40,000 every year.
For the formaldehyde in tackiness agent, traditional purifying formaldehyde way comprises: 1, plant absorption method; 2, scavenging agent sprays; 3, charcoal absorption etc.The deficiency of tradition purifying indoor formaldehyde is: 1, plant absorption method purification efficiency is limited, takes effect too slow, DeGrain; 2, scavenging agent spray effect is not lasting, and some scavenging agent just covers smell, can not eliminate formaldehyde; 3, the adsorption of gac PARA FORMALDEHYDE PRILLS(91,95) is clearly, but varying in size according to space, and the amount of placing gac is also different.In addition, charcoal absorption needs to change to a certain extent afterwards.Although the effect of gac is pretty good, the same with additive method, the formaldehyde in air can not be removed completely.
Therefore, just current state of the art does not also have highly effective method to remove completely, the content of the materials such as formaldehyde and burst size can only be made to reach bottom line by control objectionable impurities consumption and good process means.
In prior art, have and adopted common water-miscible paint to smear the method being wrapped in plate surface and carrying out closing, although PARA FORMALDEHYDE PRILLS(91,95) also can play certain sealing process, reduce the burst size of formaldehyde, but its sealing process is very limited, there is poor permeability, the defects such as coating structure is not tight, after testing, the release index of formaldehyde still exceeds standard greatly.Therefore, existing common water borne paint meets this demand.
Summary of the invention
The object of the invention is to the aqueous woodware paint proposing a kind of closed methanal, this wood lacquer can overcome the wood lacquer of prior art can not the defect of closed methanal.
For reaching this object, the present invention by the following technical solutions:
A kind of aqueous woodware paint of closed methanal, this wood lacquer is by painting host component, polyurethane curing agent component and thinner composition composition, the weight proportion of three components is 10 ︰ (6-7) ︰ (4-5), wherein paint host to be made up of the following component with parts by weight: short oil soybean oil Synolac 12-14 part, medium-oil-length ricinoleyl alcohol acid resin 16-18 part, vinyl chloride-vinyl acetate resin 4-6 part, polyethylene wax 2-4 part, porousness laponite materials 5-7 part, dispersion agent 4-6 part, defoamer 0.5-1.5 part, flow agent 1-2 part, anti-settling agent 0.3-0.5 part, N-BUTYL ACETATE 6-8 part, wherein polyurethane curing agent is made up of following component with parts by weight: toluene diisocyanate trimer 25-35 part, affixture 25-35 part of tolylene diisocyanate and TriMethylolPropane(TMP), N-BUTYL ACETATE 10-12 part, thinner is made up of following component with parts by weight: N-BUTYL ACETATE 55-65 part, propylene glycol monomethyl ether acetate 22-24 part, 1-Methoxy-2-propyl acetate 4-6 part.
The present invention compared with prior art tool has the following advantages:
1) wood lacquer of the present invention is by closing and absorbing two kinds of effects, makes to be closed formaldehyde in wooden ground not to external diffusion.The present invention introduces medium-oil-length ricinoleyl alcohol acid resin and vinyl chloride-vinyl acetate resin in paint host component, quick-drying type polyurethane curing agent toluene vulcabond is introduced in curing agent component, the cross-linking density of paint film can be made to increase, hardness of paint film improves, scrath resistance improves, and the medium-oil-length Viscotrol C alkyd toughened resin of introducing, improves the toughness of paint film, thus the formaldehyde in wooden ground can be made to be closed wherein and not to external diffusion, or spread on a small quantity.On the basis of a large amount of simultaneous test, determine the material closed and absorb formaldehyde, i.e. porousness laponite materials, it itself is porous material, the formaldehyde absorption that wooden ground overflows can be made to be fixed in paint film, and not to external diffusion, to form coordination technique effect with the sealing process of paint film itself.Make the burst size of methanal through the wooden ground of this wood lacquer brushing meet various strict standard-required completely, and effect is for many years sustainable.
2) paint film own material environmental protection: in woodenware of the present invention containing toluene dimethylbenzene ethylbenzene, not add triphen and CAC, BCS etc. poisonous, high pollution reagent, environment protection health own.
