Abstract
The invention discloses a pyroxylin lacquer with low smell, wherein the pyroxylin lacquer has no benzene hydrocarbon, and the lacquer formula includes 10 percent-25 percent by weight of at least one resin, 25 percent-55 percent by weight of at least one of alcohol ether solvent, ester solvent or alcoholic solvent, , 20 percent-50 percent by weight of at least one curing agent, plasticizer and additive, the pyroxylin lacquer of the invention uses non-benzene solvent, and ensure the superiority of pyroxylin lacquer per se, so as to effectively avoid environmental pollution produced in production, construction and using process of the benzene hydrocarbon, and health hazard to production operator and constructer.
Description
Technical field:
The present invention relates to a kind of coating compositions, relate in particular to a kind of low odor lacquer of non-toluene solvent.
Background technology:
Various in the market lacquer coating types are various, and that pyroxylin(e)finish has is economical and practical, proportioning simple, good leveling property, feel are soft and smooth, fast drying, soft, the tough and tensile competent characteristic of film forming of gloss, and can show the timber native texture especially, the effect uniqueness, pyroxylin(e)finish relies on its excellent workability and enriches changeable effect, by wide selection on woodenware perforate (American application) finishing and hotel, market, automobile, train upholstery.But, all use benzene kind solvent in the at present existing pyroxylin(e)finish manufacturing prescription, as benzene,toluene,xylene, and aromatic hydrocarbon solvents such as benzene, dimethylbenzene produce anesthesia and hormesis to nerve system of human body, even more serious is that this solvent is a kind of carcinogenic substance, can cause marrow and genetic damage as long-term contact benzene, the blood picture inspection can be found white corpuscle, thrombopenia, even leukemia takes place; Toluene can produce infringement to neural system.This kind solvent is a class to human body and environment detrimental substance all.Therefore there are the serious problem of environmental pollution in the production and the workyard of pyroxylin(e)finish, and this will inevitably make site operation personnel and neighboring area population health be subjected to serious threat.Procuring equipment solves problem of environmental pollution in the production although the manufacturer can inject capital into, and for construction with use on-the-spotly, then can't fundamentally solve it to the pollution of environment with to the harm of workmen's health.This is a long-term existence and unresolved problem.
It is that 92105305.3 Chinese invention patent discloses a kind of water soluble internal use nitrocellulose lacquer without benzene poison that name is called " production method of water soluble internal use nitrocellulose lacquer without benzene poison ", the patent No., and its formula constituent (with weight percent) is made up of 6%-20% N-BUTYL ACETATE, 4%-15% vinyl acetic monomer, 5%-10% butanols, 20%-30% nitro-cotton, 10%-25% Synolac, 2%-3% softening agent, 40-50% deionized water, 3%-6% emulsifying agent, 1% dispersion agent and 10%-15% pigment.Though being primary solvent with water, this invention replaces making solvent production without benzene toxicity pyroxylin(e)finish with toluene and dimethylbenzene.But still all with the pyroxylin(e)finish of oil-based solvent a certain distance is arranged from the weather resistance aspect from decorative effect, therefore, this patent of invention still can't solve benzene and pollute and the murder by poisoning problem under the prerequisite of guaranteeing the high-performance of pyroxylin(e)finish own.
Summary of the invention:
Pollute and the murder by poisoning problem for solving the benzene that exists in the pyroxylin(e)finish production that exists in the prior art and the construction, and guarantee the high-performance of pyroxylin(e)finish own, the present invention proposes the technical solution of the pyroxylin(e)finish of following not containing benezene solvent:
The basal component of low odor lacquer prescription of the present invention comprises following composition, and weight percent is separately:
A, at least a resin are selected from the middle of the Synolac, Gum Rosin at least aly, and consumption is 10wt%-20wt%;
B, solvent: it is central at least a to be selected from pure ether solvent, esters solvent and alcoholic solvent, and consumption is 38wt%-55wt%;
C, solidifying agent nitro-cotton, consumption are 20wt%-25wt%;
D, softening agent, consumption are 5wt%-15wt%;
E, the leveling auxiliary agent that contains polysiloxane, the leveling auxiliary agent that contains CALCIUM ACRYLATE, froth breaking auxiliary agent, coating hide in the flavor auxiliary agent at least a, and consumption is 1wt%-2wt%.
For satisfying the special performance of pyroxylin(e)finish of the present invention, satisfy the individual character requirement when constructing, the present invention has added this area additive in common knowledge, reaches as the adding solidifying agent and improves intensity; Suppleness when the interpolation softening agent can be promoted the pyroxylin(e)finish construction.
We find that after deliberation described resin preferably is selected from fatty acid modified short oil-ity alcohol acid resin, central a kind of or its combination of Malin's acid modified rosin resin.
In addition, add hardened resin that is less than or equal to 4wt% and the flatting silica that is less than or equal to 4wt% and can optimize the performance of pyroxylin(e)finish of the present invention and can improve its gloss, at this moment, the weight percent of described resin is 10wt%-18wt%.
For obtaining the pyroxylin(e)finish of white, can add the titanium dioxide that is less than or equal to 4wt%, at this moment, the weight percent of described resin is 10wt%-18wt%.
After deliberation, better effects if when we find that described solvent is combination solvent, pure ether solvent of the present invention is selected ethylene glycol monobutyl ether for use, described esters solvent is selected from one of 1-Methoxy-2-propyl acetate, butylacetate, ethyl acetate, methylcarbonate or its combination, and described alcoholic solvent is Virahol or ethanol.
Softening agent of the present invention is selected from the middle of the dibutyl phthalate, dioctyl phthalate (DOP), adipate polyester, epoxidised soybean oil at least a.
Compared with prior art, pyroxylin(e)finish of the present invention uses non-toluene solvent, guarantee simultaneously the high-performance of pyroxylin(e)finish itself again, thereby effectively avoided environmental pollution that benzene kind solvent produces and to the harm of production operation personnel and workmen's health in production, construction and use, realized high-quality, environmental protection, harmless purpose.
