Description

A kind of coil coating and preparation method thereof of aluminium sheet roller coating
Technical field
The present invention relates to fine chemistry industry technical field of coatings；The coil coating of especially a kind of aluminium sheet roller coating and its preparation Method, the coating apply the ectonexine of the screw lid on bottle.
Background technique
Screw lid on bottle applies coating roller coating on aluminium sheet using piece and is coated with, and technique: first applying back and apply, toast 20 minutes, then Coating surface applies, and toasts 20 minutes system lids.Above-mentioned production technology is complicated and process is longer, consumes energy big, at high cost, production efficiency is low.
Summary of the invention
The purpose of the present invention is to provide a kind of suitable coil coating mode and performance can meet the aluminium sheet roller coating use of wine lid requirement Coil coating.
Another object of the present invention is to provide a kind of energy savings, aluminium sheet roller at low cost and significantly improving production efficiency The coil coating preparation method of painting.
The object of the present invention is achieved like this:
A kind of coil coating of aluminium sheet roller coating, characterized in that including following components and its mass percent: macromolecule polyester Resin 15-30%；Epoxy-modified polyester 10-20%；Modified benzoguanamine resin 2-10%；Blocked polyisocyanate 3- 10%；Catalyst 0.1-0.3%；Adhesive agent 1-2%；Pigment 6-15%；Antisticking auxiliary agent 0.3-0.6%；Levelling agent 0.1-0.3%；It is molten Agent 10-30%.
The present invention can improve further below:
Further, the volatility of the solvent is very fast.
Further, the drier is compound, not only can be shortened drying time, but also can reduce baking temperature.
Further, the pigment is nanoscale, including white, red and blue.
Further, the levelling agent includes fluorine carbon and organosilicon.
Coil coating of the invention, by using the matrix resin of two kinds of different characteristics, so that coil coating is after high-temperature baking, Its deep drawability, ethanol-tolerant impregnate, and high temperature resistant sterilization etc. is attained by the requirement of wine lid.
It is another object of the present invention to what is be achieved:
A kind of preparation method of the coil coating of aluminium sheet roller coating, characterized in that include the following steps:
Step 1: pigment is pre-dispersed；Suitable macromolecule polyester and solvent is added in dispersion cylinder, face is added while stirring Material, dispersion stir evenly, and dispersion liquid is made；
Step 2: the grinding of pigment；It is 3-8 μm that above-mentioned dispersion liquid, which is ground to fineness with sand mill,；
Step 3: dispersion cylinder is added in the graining paste for being ground to fineness qualification, and remaining material is added, 20-40 is sufficiently stirred Minute；
Step 4: toning；It is required according to the form and aspect of all kinds of wine lids, is mixed colours using nanoscale mill base coating, and stirred equal It is even；
Step 5: packaging；It is filtered, is packaged in pail pack using 750-850 mesh filter screen.
Beneficial effects of the present invention are as follows:
(1) coil coating of aluminium sheet roller coating of the present invention, after high-temperature baking, deep drawability, ethanol-tolerant impregnates, and high temperature resistant is killed Bacterium etc. is attained by the requirement of wine lid, and is suitble to coil coating mode.
(2) coil coating of the present invention is coated on aluminium sheet by coil coating mode, and producing only piece painting originally could be coated with Product improve production efficiency, reduce production cost, obtain high-end wine lid coating to greatly shorten baking time It is widely applied.
(3) it since piece painting is toasted within 15 minutes using 180 DEG C, and after being changed to coil coating, only toasts 50 seconds, it should to meet Ensure the performance of coating, and be unable to the high request of haftplatte, following scheme has been used on formula: 1. macromolecule polyester resins can guarantee The deep drawing quality of coating；2. matching epoxy-modified polyester with adhesive agent, increase the adhesive force and alcohol resistance of coating；3. using enclosed type Polyisocyanates guarantees that boiling coating is resistance to and high temperature sterilization；4. using Antisticking auxiliary agent, haftplatte after winding is prevented.
Specific embodiment
The invention will be further described combined with specific embodiments below:
A kind of coil coating of aluminium sheet roller coating, characterized in that including following components and its mass percent: macromolecule polyester Resin 15-30%；Epoxy-modified polyester 10-20%；Modified benzoguanamine resin 2-10%；Blocked polyisocyanate 3- 10%；Catalyst 0.1-0.3%；Adhesive agent 1-2%；Pigment 6-15%；Antisticking auxiliary agent 0.3-0.6%；Levelling agent 0.1-0.3%；It is molten Agent 10-30%.
As more specific scheme, the volatility of the solvent is very fast；Drier be it is compound, when both can be shortened dry Between, and baking temperature can be reduced, and pigment is nanoscale, including white, red and blue etc..And levelling agent includes fluorine carbon and has Machine silicon.
A kind of preparation method of the coil coating of aluminium sheet roller coating, characterized in that include the following steps:
Step 1: pigment is pre-dispersed；Suitable macromolecule polyester and solvent is added in dispersion cylinder, face is added while stirring Material, dispersion stir evenly, and dispersion liquid is made；
Step 2: the grinding of pigment；It is 3-8 μm that above-mentioned dispersion liquid, which is ground to fineness with sand mill,；
Step 3: dispersion cylinder is added in the graining paste for being ground to fineness qualification, and remaining material is added, 20-40 is sufficiently stirred Minute；
Step 4: toning；It is required according to the form and aspect of all kinds of wine lids, is mixed colours using nanoscale mill base coating, and stirred equal It is even；
Step 5: packaging；It is filtered, is packaged in pail pack using 750-850 mesh filter screen.
As scheme more, in the step 2, it is 5 μm that dispersion liquid, which is ground to optimum fineness value with sand mill,；Step In three, remaining material is added, is sufficiently stirred 30 minutes；In step 5, is filtered, be packaged in pail pack using 800 mesh filter screens.
Since piece painting is toasted within 15 minutes using 180 DEG C, and after being changed to coil coating, only toast 50 seconds, it should be true to meet The performance of friendly coating, and it is unable to the high request of haftplatte, following scheme has been used on formula: 1. macromolecule polyester resins, which can guarantee, to be applied The deep drawing quality of material；2. matching epoxy-modified polyester with adhesive agent, increase the adhesive force and alcohol resistance of coating；3. more using enclosed type Isocyanates guarantees that boiling coating is resistance to and high temperature sterilization；4. using Antisticking auxiliary agent, haftplatte after winding is prevented.
