Aluminum is that nature stores one of the abundantest metallic element, due to aluminum and alloy thereof there is little, the good heat conduction of proportion and electric conductivity, reflective is strong, be prone to processing and forming and the physical and chemical performance of excellence, the advantage such as cheap, the raw material of aluminium strip is fine aluminium or aluminium alloy casting aluminum volume, rolling aluminum volume, through the thin plate aluminum volume that cold rolling mill is different-thickness, width, further according to purposes, longitudinally cut the aluminium strip into different in width through slitter.In order to prevent aluminium strip to be corroded, its surface typically can be processed by people, and in existing aluminium sheet coating, major part also has a certain amount of organic solvent, and during high-temperature baking film forming, solvent volatilizees, to environment.Existing aluminium sheet coating does not much reach higher requirement, can not meet the application demand of many occasions.
Summary of the invention
It is an object of the invention to provide a kind of green aluminium strip coating, be achieved through the following technical solutions:
A kind of green aluminium strip coating, is made up of following component: methyl methacrylate 12 parts, Polyethylene Glycol 18 parts, ethyl acrylate 22 parts, methyl silicon resin 30 parts, sodium tripolyphosphate 1 part, Tissuemat E 4 parts, ethoxylated trimethylolpropane triacrylate 1 part, 8 parts of Colophonium, nano titanium oxide 2 parts, triglycidyl isocyanurate 2 parts, PTMG 1 part, emulsifying agent 1 part by weight；The granularity of nano titanium oxide is 45-48nm.
Further, described nano titanium oxide is through processing: first presses mass ratio mixing stearic acid and the toluene of 6.23:100, is then added to into by nano titanium oxide, first it is heated to 42 DEG C, is incubated 10 minutes, is again heated to 68 DEG C, after being incubated 15 minutes, it is cooled to room temperature, filters out nano titanium oxide, washing, dry, by the surface of nano titanium oxide is processed, its surface hydrophilicity can be improved, it is possible to increase its dispersibility and the stability of raising coating.
Further, described ethyl acrylate, ethoxylated trimethylolpropane triacrylate processes through premix with methyl silicon resin: by ethyl acrylate, ethoxylated trimethylolpropane triacrylate mixes with methyl silicon resin, when being heated to 55 DEG C, add again mixture weight 1.25% Kaolin, after mix homogeneously, temperature is reduced to 42 DEG C, it is ground 2 hours, greatly improve its structure organization performance, improve ethyl acrylate, ethoxylated trimethylolpropane triacrylate and methyl silicon resin and the compatibility of other composition, extend the service life of coating, enhance coating corrosion resistance energy.
Further, described emulsifying agent is glyceryl monostearate.
A kind of manufacture method of green aluminium strip coating, including:
1) methyl methacrylate is mixed with Polyethylene Glycol, after mix homogeneously, add emulsifying agent and carry out composite emulsifying, and when being heated to 65-80 DEG C, add the nano titanium oxide after modification, after mix homogeneously, carry out stirring 20 minutes with 900r/min speed.
2) in rapid dispersion machine add 1) in gained raw material, after 5 minutes, add ethoxylated trimethylolpropane triacrylate, neck dioctyl phthalate, sodium tripolyphosphate again, after 10 minutes, add Colophonium, triglycidyl isocyanurate and the polyethylene wax mixture processed through premix, period, continual with the stirring of 1200r/min rotating speed；
3) to 2) in raw material add PTMG and treated ethyl acrylate and methyl silicon resin mixture to, be heated to 80 DEG C, after stirring 40 minutes with 2800r/min speed, stand.
Being coated on the aluminium foil having precoated subbing by this aluminium strip coating, form aluminium strip coating by baking-curing, baking condition is furnace temperature: 212 DEG C, corresponding aluminum foil plate temperature: 170 DEG C, baking time: 6.55 seconds.
Sodium tripolyphosphate is as little dispersal agent molecule, although having low cost and good initial dispersion effect, but its shortcoming is also apparent from, it is unfavorable for that good film forming and long dispersion stability are poor, the present invention coordinates sodium tripolyphosphate to solve these problems by adding Colophonium with treated titanium dioxide so that coating of the present invention has more preferable film property and long dispersion stability.
The invention has the beneficial effects as follows: aluminium strip coating of the present invention can coordinate coating to use with various subbings, its film formed on object has excellent corrosion resistance, excellent anti-fouling performance and good tack, lubricity and corrosion resistance, hardness height, damage resistant, salt spray resistance, acid and alkali-resistance, glossiness are high, reusable at old coating surface, do not result in paint film damage, superpower paint film flexibility etc..Aluminium strip coating not only green non-pollution of the present invention, compared to general air-conditioning, uses under same environment, wants high 0.75 times through the air-conditioning life-span that coating of the present invention processes.
