Abstract
The invention discloses a yellowing-resistance nitrolacquer and is characterized by comprising the following components in percentages by weight: 60-70% of nitrocotton-containing main agent, and 30-40% of diluent, wherein the nitrocotton-containing main agent comprises the following ingredients in the percentages by weight: 12-25% of nitrocotton, 20-25% of more than one polyester resin, 1-5% of epoxidized soybean oil, 6-21% of pigment or stuffing, 0.5-1% of dispersant, 0-0.5% of defoamer, 0.5-1% of flatting agent, 0.5-1% of gloss wax, 0-10% of extinction powder, and 12-18% of first solvent composed of more than one esters and alcohols; and the diluent is selected from any one or more than two of esters, ethers and aromatic hydrocarbons by mixing. The yellowing-resistance nitrolacquer of the invention has good transparency, hardness, scratch resistance and yellowing resistance.
Description
Technical field
This discovery relates to a kind of Yellowing-resistant nitro lacquer.
Background technology
Nitro paint has the physicals of a series of excellences, and the one, surface drying is rapid, and nitro paint belongs to volatile dry type coating, relies on solvent evaporates to make the coating curing film forming.The 2nd, the damaged back of filming is prone to repair, and nitro paint belongs to reversibility coating, and filming still of promptly doing solid work fully can be by former dissolution with solvents, therefore when paint film sustains damage, very easily repair with basically identical originally, do not see the repairing vestige.The 3rd, the coatings decoration excellent performance, the look of filming is shallow, transparency is high, hard wear resistant, and physical strength and certain water resistance are preferably arranged, and is widely used in the application of noble furniture, senior musical instrument, artwork etc.But compare with other coating, weathering resistance and yellowing resistance that nitro paint is filmed are relatively poor, in use than easy damaged, because the solid of coating own is low, unfavorable factors such as a large amount of obnoxious flavour volatilization contaminate environment are arranged after the construction.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, a kind of Yellowing-resistant nitro lacquer is provided.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of Yellowing-resistant nitro lacquer is characterized in that, comprises following component according to weight percent:
Contain nitro-cotton host 60～70%;
Thinner 30～40%;
The described nitro-cotton host that contains comprises following composition:
Weight percent is 12～25% nitro-cotton;
Weight percent is 20～25% more than one vibrin;
Weight percent is 1～5% epoxy soybean oil;
In pigment and the filler one or more, weight percent are 6～21%;
Weight percent is 0.5～1% dispersion agent;
Weight percent is 0～0.5% skimmer;
Weight percent is 0.5～1% flow agent;
Weight percent is 0.5～1% zero diopter wax;
Weight percent is 0～10% flatting silica;
It by more than one ester class, weight percent that alcohols constitutes 12～18% first solvent;
Described thinner is selected from ester class, ethers, the aromatic hydrocarbon one or more and mixes.
Preferably, described vibrin is by acrylic acid modified vibrin.More preferably be that acrylic acid modified vibrin solid content is about 70～75%.
Preferably, described face, filler are that one or more mix by tinting pigment, pigment extender, specific functionality filler etc., like talcum powder, Triple Pressed Stearic Acid zinc powder etc.
Preferably, described dispersion agent is to use the polyurethane class high molecular compound of block copolymerization or the ROHM high molecular polymer of long-chain line style, like Disperbyk-2000, Disperbyk-200.
Preferably, described skimmer is to use fluorine modified polyorganosiloxane multipolymer, like moral modest 6500.
Preferably, described flow agent is to use organically-modified siloxanes, like EFKA-S030, EFKA-S090.
Preferably, described zero diopter wax is to use polytetrafluoroethylmodified modified polyethylene wax, as TATSUMORL 7200, the modest FA-115 of moral.
Preferably, described flatting silica is to use silica polymer, like Degussa OK-500, OK-412.
Preferably, described first solvent is to be mixed by 40～45% propylene glycol monomethyl ether acetate, 40～60% ethanol and 0～20% butyl ester.
A kind of preparation method of the present invention is: earlier first solvent and nitro-cotton are stirred; After nitro-cotton dissolves fully, add acrylic acid modified polyester resin and dispersion agent again and carry out pre-dispersedly, the back that stirs adds that shredder is ground to fineness less than 10 microns on pigment, filler, the flatting silica, adds skimmer, epoxy soybean oil, zero diopter wax, flow agent again; After the stirrer high speed dispersion; Last shredder is ground to fineness less than 20 microns, adds residual solvent again, transfers to suitable viscosity.
Yellowing-resistant nitro lacquer among the present invention; Owing to added acrylic acid modified polyester resin in the prescription; Transparency, hardness and the wear resistance of filming and can not only reach good have been improved weathering resistance and yellowing resistance simultaneously, and coating itself is superior to the general high solids content of pyroxylin(e)finish on the market; No longer occur a large amount of obnoxious flavour volatilizations after the feasible construction, thoroughly solved factor of environmental pollution.
1, the described vibrin of prescription sees through acrylic acid modified technology, not only possesses the good transparency of nitro paint, hardness and scrath resistance, has also increased snappiness, endurance and yellowing resistance, for the overall performance of paint film bigger lifting is arranged.
2, the described zero diopter wax of prescription is polytetrafluoroethylmodified modified polyethylene wax, can improve the smoothness of film coated surface and promote the scrath resistance of coating surface greatly, and it can not make the phenomenon of coating surface generation gonorrhoea with the paint binder compatibility is good, be prone to disperse.
The present invention is specially adapted on the woodenware products such as furniture, bedding, musical instrument good wear resistance, endurance and ornamental is provided.Among the present invention,, make this pyroxylin(e)finish have anti-xanthochromic speciality owing to used acrylic acid modified polyester resin.
