Description
Technical field
The present invention relates to a kind of glass ink, be specifically related to a kind of ink be applied on coated glass and preparation method thereof.
Background technology
It is reflecting glass that coated glass (ReflectiveGlass) is also referred to as, and its preparation technology is at one or more layers metal of glass surface coating, alloy or compound film to change glass optics properties, thus meets certain specific requirement.Although coated glass can make the performance of glass reach particular requirement, after plated film, change the surface property of glass, make if desired to print coated glass then very difficult.The sticking power of tradition ink and printing cannot meet the requirement on coated glass surface, apply the problem that glass ink of the prior art often occurs that opacifying power is poor, sticking power is unstable, acid-proof alkaline is poor.
Application number is provide a kind of a kind of glass ink be made up of thermoplastic acrylic resin, vinyl acetate resin, oil-soluble colourant, organo-siloxane adhesion promoter and solvent in the Chinese patent of " a kind of coding glass ink of high adhesive force " by name of 201410391640.X, can effectively be attached on glass, there is high sticking power.But the program does not propose whether possess sticking power high equally for coated glass yet.
Summary of the invention
For the deficiencies in the prior art part, the invention provides a kind of ink be applied on coated glass, the ink in the present invention is good, the strong covering power of sticking power on coated glass not only, and acid-fast alkali-proof salt spray resistance is good.
Technical problem to be solved by this invention is achieved by the following technical programs:
Be applied to the ink on coated glass, each component that described ink comprises and mass percent as follows:
Silicone modified polyester resin 45-60%
Stopping composition 8-10%
Linking agent 6-10%
Flow agent 0.5-1%
Dispersion agent 0.25-0.8%
Defoamer 0.6-1.2%
Polymeric polyisocyanate 5-12%
Balance of solvent
Wherein preparation method's step of silicone modified polyester resin is:
Step one, be 38% methyl chlorosilane by mass percent, 15% toluene, 35% butanols, under 65-68 DEG C of condition, react 4-6 hour after 12% methyl propanediol mixing, reactant is hydrolyzed condensation, adds isopropanol floride after having reacted and be interpreted into the silanol intermediate that solid content is 60%.This intermediate product silanol is the most stable when solid content is about 60% in a solvent.
Step 2, the silanol intermediate being 60% by vibrin and gained solid content in step one mixes with mass ratio 1:1.85 ~ 2.08, add simultaneously account for vibrin quality 1% butyl (tetra) titanate as catalyzer, be warming up to 150 ~ 180 DEG C of polyreactions after three being mixed, generate silicone modified polyester resin.Catalyzer in this step also can use orgnometallic catalyst, and as organolithium catalyst, organic ruthenium catalyzer, but effect is not as butyl (tetra) titanate.
Step 3, pours into the silicone modified polyester resin generated in step 2 in ethanolic soln and leaves standstill 12-24 hour, recycling ethanol purge 2-3 time after filtering, then vacuum-drying under 75-85 DEG C of condition.
Vibrin is by poly-basic organic acid and polynary Organic Alcohol in the presence of a catalyst through the superpolymer that esterification and polycondensation obtain, and each chain internode is all be connected with ester group, therefore is referred to as polyester.Vibrin has the advantages such as light, plentiful, hardness is high, acid and alkali-resistance is corrosion-resistant, but there is the shortcoming of application property difference.Organosilicon is the organic polymer synthetic materials containing element silicon in molecular backbone chain, that a class half is inorganic, half organic compound, have the performance of organic materials and inorganic materials concurrently, its scale resistance is good, resistance to acids and bases mildew resistance is excellent, but silicone resin exists solidification value high (needing about 300 DEG C), set time is long, paint film adhesion is poor, organic solvent resistance is poor shortcoming.In the present invention, utilize methyl chlorosilane and alcohols generation hydrolysis-condensation reaction to form silanol intermediate and carry out modification to vibrin, the silicone modified polyester resin formed can obtain the advantage of bi-material.
In ink of the present invention, silicone modified polyester resin is applied as resin of binding property, as ink agent structure and exist, make the ink not only strong adhesion in the present invention, and acid and alkali-resistance salt spray resistance ability is good, effectively can reduce the temperature and time of solidification when ink uses simultaneously.
Described stopping composition is barium sulfate or talcum powder, in order to regulate ink viscosity.
The silicone modified polyester resin prepared in the present invention both had thermoset, had again certain thermoplastic property, so in the process making ink solidification, and must with the use of linking agent and solidifying agent.Described linking agent is amino crosslinker, amino crosslinker and the composite use of polymeric polyisocyanate, can make the ink rapid solidification at short notice in the present invention, promotes the covering power of ink.Amino crosslinker in the present invention can adopt commercially available amino crosslinker, as melamine crosslinkers (TS-MF).Polymeric polyisocyanate uses as main solidifying agent.Amino crosslinker and polymeric polyisocyanate in use should one in front and one in back use, and namely first add amino crosslinker, add polymeric polyisocyanate more before printing, ink printing best results.
Described flow agent is polydimethylsiloxane flow agent or polymethyl benzene radical siloxane flow agent, these two kinds of flow agents form smooth, smooth, a uniform film to the ink that can impel in the present invention in drying and forming-film process, the surface tension of effective reduction oil film, form the homogeneity of pattern after promoting ink setting, improve covering power further.
Dispersion agent in the present invention preferably uses in fatty acid polyglycol ester, polyacrylamide, methyl amyl alcohol
One or more, effectively can prevent sedimentation and the cohesion of particle in ink.
Described defoamer is silicone emulsion or natural fats and oils.
Single-component solvent can not dissolve effectively completely to the component in the present invention, therefore the solvent used in the present invention is mixed solvent, and described solvent is butylacetate, Virahol, ethyl acetate mix with volume ratio 1:1:1.
Further, also can add carbon dust in described ink or titanium dioxide is mixed colours, when the addition of carbon dust reaches 9% of ink quality, the effect that this ink brushes is ater glossy surface; When the addition of titanium dioxide reaches 15% of ink quality, the effect that this ink brushes is pure white glossy surface.
The using method of described ink is: be stirred to except solidifying agent polymeric polyisocyanate by described ink raw materials evenly, be then ground to desired particle size and make finished product ink; Add solidifying agent polymeric polyisocyanate by above-mentioned ink before printing, after mixing, can silk screen printing be carried out; After being completed for printing, folder being placed in baking oven to toast under 160-180 DEG C of condition and making ink solidification shaping in 5-10 minute.
The present invention has following beneficial effect:
1, the sticking power of the ink in the present invention on coated glass is good, strong covering power.
2, the ink acid-fast alkali-proof salt spray resistance in the present invention is good.
3, the ink using method in the present invention and shading process simple, the solidification value low time is short.
