Description
Technical field
The invention belongs to technical field of coatings, relate to a kind of pyroxylin(e)finish, particularly the lower pyroxylin(e)finish of a kind of content of volatile organic compound.
Background technology
Pyroxylin(e)finish is current more common woodenware and finishing coating.The main film forming matter of pyroxylin(e)finish is to take nitro-cotton as main, coordinates the soft or hard resins such as Synolac, modified rosin resin, acrylic resin, aminoresin jointly to form.Generally also need to add the softening agent such as dibutyl phthalate, dioctyl ester, blown castor oil.Solvent mainly contains the true solvents such as ester class, ketone, alcohol ethers, the thinners such as the solubility promoters such as alcohols and benzene class.Pyroxylin(e)finish is mainly used in the application, house decoration of woodenware and furniture, generally decorates the aspects such as application, coated metal, general cement application.
Pyroxylin(e)finish advantage is that decoration function is better, easy construction, dry rapidly, less demanding to painting environment, has good hardness and brightness, is not prone to film defect, repairs easily.Shortcoming is that solid content is lower, need to use a large amount of volatile organic compoundss, and human body and environment are had a negative impact.
Therefore, people attempt development compared with the pyroxylin(e)finish of low VOC content, and for example Chinese invention patent ZL 200610062641.5 discloses a kind of low odor lacquer.The basal component of this paint formula and separately weight percent are: at least one resin, and consumption is 10%-25%; At least one alcohol ether solvent, esters solvent or alcoholic solvent, consumption is 38%-55%; In the middle of at least one solidifying agent, softening agent, auxiliary agent, consumption is 20%-50%, non-toluene solvent is used in this invention, guarantee again the high-performance of pyroxylin(e)finish own simultaneously, thus environmental pollution and the healthy harm to production operation personnel and workmen of effectively having avoided benzene kind solvent to produce in production, construction and use procedure.
And for example, Chinese invention patent application 201010103408.3 discloses a kind of environmental-friendly nitryl wood lacquer, nitro-cotton, Synolac, softening agent, alkoxide mixed solvent, Gum Rosin, talcum powder, defoamer, flow agent, dispersion agent, anti-settling agent, Zinic stearas, titanium dioxide and flatting silica is made under certain technical process not to the environmental-friendly nitryl wood lacquer containing PAHS etc. according to certainweight per-cent.Significantly reduce the toxicity of wood lacquer, improved security of the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of novel low VOC pyroxylin(e)finish.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A low VOC pyroxylin(e)finish, is comprised of following component by mass percentage:
Solvent 25～39.5%;

The effect of above-mentioned solvent is each component of dissolving in formula, adjusts the viscosity of rare whole system, and while adopting those skilled in the art to carry out coating, conventional organic solvent can be realized the present invention; The concrete mixture of pressing dimethylbenzene 10%, butyl ester 20%, methyl iso-butyl ketone (MIBK) 35%, ethyl ester 10% and propyl carbinol 15%, pimelinketone 10% equal proportion preparation.
Above-mentioned 1/16s nitro-cotton, 1/4s nitro-cotton, its effect is that the hardness of 1/16s nitro-cotton is high, viscosity is low, the product that can improve the hardness of paint film and make high-solid lower-viscosity, the viscosity of 1/4s nitro-cotton is relative not high yet, snappiness relative 1/16 is good, is used herein to snappiness and the viscosity of adjusting paint film.These two kinds of nitro-cottons adopt any commercially available nitrogen content 11.8%-12.3%, and the nitro-cotton of acidity≤0.05 all can be realized the present invention.
Above-mentioned its effect of Malin's acid resin is the hardness that improves paint film, gloss, fullness ratio etc., adopts commercially available any Malin's acid resin all can realize the present invention.MRP-1203, the MRG-1203 of Deqing base unmodified resin, MRG-1204A etc.
Above-mentioned its effect of synthetic fatty acid modified alkyd resin is the snappiness that increases paint film, sticking power, gloss, fullness ratio etc., adopt this commercially available resinoid all can realize, as Dehua work AK-2380D, AK-2380A, vertical greatly A-930, three wood 3380, Changxing 3755-X-80 etc.Preferably the 3755-X-80 of Changxing chemical industry can realize the present invention.
Above-mentioned flow agent adopts polyether-modified organosilicon flow agent, it has very low surface tension, and slipping is fabulous, can reduce greatly the friction resistance of paint film, thereby the anti scuffing performance that improves paint film, this organosilicon flow agent adopts commercially available organosilicon flow agent all can realize the present invention.As BYK-300, BYK-306, TEGO410, TEGO450 etc., the BYK300 of preferred German Bi Ke company.
The effect of above-mentioned softening agent is to regulate snappiness, on market, permitted eurypalynous softening agent and can be selected (as phthalic acid salt, ammonia ester oil, terephthalic acid salt, blown castor oil etc.), consider environmental-protecting performance, it is the mixture of ratio preparation in 1:1 that the present invention has selected dioctyl terephthalate and blown castor oil; This dioctyl terephthalate and blown castor oil adopt any commercially available product all can realize the present invention.
The effect of above-mentioned defoamer is to eliminate the foam that painting process and construction process produce, adopt commercially available defoamer all can realize the present invention as 6703 of lid Si Tafu, the BYK065 of Bi Ke is, the EFKA-2020 of vapour bar etc.
Compared with prior art, tool of the present invention has the following advantages:
The present invention is by selecting the low viscous nitro-cotton of lower molecular weight, and low viscous Malin's acid resin, and by the combination collocation of various auxiliary agents, can prepare the pyroxylin(e)finish of high solids content, reduces the quantity discharged of VOC, improves the environmental-protecting performance of product.
