Abstract
The present invention utilizes homemade commercially available ordinary amine baking varnish, urethane resin, Synolac and relevant auxiliary agent to be batching, adopts unique Recipe, prepares a kind of high-grade low temperature baking enamel.It can be sprayed on the various base materials, can be at 60-80 ℃ of film-forming, and paint film is tough and tensile, glossiness is high, strong adhesion, NBC protective performance and guarantor's light tint retention can be good.
Description
The invention belongs to coating, be specifically related to a kind of blending process of low temperature baking enamel.
Widely used amine baking varnish in the industrial coating, generally all must pass through the oven dry of long period about 120 ℃ could film forming.Be to shorten the storing time of amine baking varnish, succeed in developing " quick-dry type amine baking varnish " mid-term in succession in the eighties both at home and abroad.For example, it is " super quick-setting amino baking finish " patent application of 871028433 that there is application number in China, open on February 15th, 1989.It is intended to change the Synolac structure in the amine baking varnish, use two kinds, three kinds or the multiple Synolac that belongs to monobasic, binary, ternary or polycarboxylic acid preparation respectively, under the condition of heating, impel functional group's (butoxy) open chain in the aminoresin, with hydrogen bond or the crosslinked film forming of hydroxyl in the Synolac, realized the purpose that shortens drying time and improve painting quality; But storing temperature still needs more than 80 ℃.Japanese kokai publication sho JP61,285,267 disclose a kind of cold curing paint, and it reaches 98% at the coating gloss that 60 ℃ of bakings obtained in 30 minutes, and has good weathering resistance, water tolerance and oil-proofness; But this coating is that multi-component esters of acrylic acid is formulated, and starting material are rare expensive, and blending process is also quite complicated.
The objective of the invention is to utilize homemade commercially available common coating to adopt easy Recipe for raw material, prepare and a kind ofly can be sprayed at various base materials, and can be under 60～80 ℃ low temperature film-forming, and the mixed type high gear low temperature baking enamel that paint film is tough and tensile, glossiness is high, strong adhesion, NBC protective performance and guarantor's light tint retention can be all good.
The present invention is achieved in that
In 100 parts of (weight, as follows) commercially available amine baking varnishs, adding amino lacquer diluent (dimethylbenzene 90%, butanols 10%) to viscosity is 20～30 seconds (being coated with one 4 glasss, as follows), and middling speed (700～800 rev/mins, as follows) stirred 3 minutes; Slowly add 1～10 part of commercially available Synolac again, (1400～1500 rev/mins) stirred 5 minutes at a high speed; Again
Slowly add 0.01～0.10 part of amine curing agent (for example quadrol), middling speed stirred 5 minutes, and (below 100 rev/mins, as follows) stirred 5 minutes at last at a slow speed, and be stand-by as the A component with this.
In 50～200 parts of urethane resins, adding thinner for polyurethane coating (dimethylbenzene 60%, pimelinketone 15%, N-BUTYL ACETATE 25%) to viscosity is 22～25 seconds, ketone solvent (for example acetone) middling speed that slowly adds 5～30 parts of lower boilings, low volatility then stirred 5 minutes, with this as the B component.
At last, the A component is slowly joined in the B component, middling speed stirred 5 minutes, stirred at a slow speed 5 minutes again, added 0.1～1.0 part of dehydrated alcohol before finishing stirring.
Like this, even if low temperature baking enamel process for preparation of the present invention finish.Shelve and to use in 20 minutes.
In addition, it should be noted that:, must in 24 hours, finish using in winter according to the low temperature baking enamel of the inventive method preparation; Must in 12 hours, finish using in summer.
Low temperature baking enamel according to the inventive method preparation can be sprayed on the various base materials securely; Can dry film forming in 0.5～2 hour 60～80 ℃ of temperature, paint film is tough and tensile, and glossiness reaches more than 97%; But 180 ° of flawlesses of application model centreless bending, destructive hammering do not fall lacquer; Through the checking of application on aluminium zinc and IBS plastics, NBC protective performance and guarantor's light tint retention can be all senior above GB TQ2 first JB/Z111-74(
Car body-finishing coating).Because storing temperature is low, can be used for
The baking of car renovation integral spray, and do not need device in the dismounting vehicle, the saving of labor economizes expense.
Embodiment 1
The low temperature baking enamel of Jiangling motor large lampshade (IBS plastics) application black.
Prescription: 100 parts of black amine baking varnishs, 10 parts of amino lacquer diluents, 5 parts of Synolac, 0.1 part of quadrol, 60 parts of urethane resins, 25 parts of thinner for polyurethane coatings, 20 parts in acetone, 0.3 part of industry anhydrous ethanol.
Above-mentioned recipe ingredient is mixed with A component and B component by preceding method, under agitation the A component is slowly joined in the B component then, add industry anhydrous ethanol at last, shelve again after 20 minutes and can use.To toast in the input far infrared drying room of large lampshade spraying back, baking is 0.5 hour under 70 ℃ of temperature, obtains the splendid black large lampshade of painting effect.
Embodiment 2
The low temperature baking enamel of the super door lock application of aluminium zinc scarlet.
Prescription: 80 parts of red amine baking varnishs, 20 parts of black amine baking varnishs, 10 parts of amino lacquer diluents, 4 parts of Synolac, 0.08 part of quadrol, 80 parts of urethane resins, 25 parts of thinner for polyurethane coatings, 10 parts in acetone, 0.2 part of industry anhydrous ethanol.
Compound method is with aforementioned identical.To toast in the input far infrared drying room of the super door lock spraying of aluminium zinc back, 80 ℃ of bakings 0.5 hour, effect was splendid.
