The invention discloses an epoxy modified water-soluble tape coating and a preparation method thereof. The epoxy modified water-soluble tape coating is prepared from an epoxy modified water-soluble acrylic resin, a dispersing agent, a defoaming agent, titanium dioxide, pigment, deionized water, a cosolvent and a water-soluble amino resin, has the hardness of 2H and the adhesive force of less than or equal to level 1, has the impact strength 50kg impact and recoil pass, has the gloss of 85 degrees at the temperature of 60 DEG C and resists 3 percent NaCl pass for 72 hours, 3 percent NaOH pass for 72 hours and 3 percent HCl pass for 72 hours. The coating has the coating performance and high reaction activity of the acrylic resin coating, and has high weather resistance, high adhesive force of the epoxy resin coating, high impact resistance, high wear resistance and high corrosion resistance; in the formula, a low organic solvent content is adopted, the coating is non-toxic, environment-friendly and safe, and the physical and chemical properties achieve and are superior to those of the traditional solvent type products.
Description
Technical field
The present invention relates to a kind of coating and preparation method, is a kind of epoxide modified water-soluble band tape paint and preparation method specifically.
Background technology
Band tape paint belongs to extraordinary tailor-(made) coating, only is confined to measure the application with steel tape.Because self-characteristic and the coating process requirement of steel tape, the performance requriements of band tape paint is had: the high adhesive force of paint film, shock resistance, snappiness and good wear resistance, other performances such as preservative property etc. also need be taken into account.The band tape paint of understanding at present, basic still based on solvent based coating, and these manufacturers are under the pressure of user's requirement, at aspects such as the heavy metal content of pigment, film-forming speed, certain progress has been arranged technically, but it is basic, and organic solvent content can't reach up-to-date environmental requirement.Along with country improves day by day to environmental protection and requirement of safe production, original solvent-borne type product and contain heavy metal, the band tape paint that contains poisonous pigment will become history.
Summary of the invention
The purpose of this invention is to provide a kind of epoxide modified water-soluble band tape paint and preparation method, to overcome the problem that prior art exists.
Realize that the technical scheme that the object of the invention is taked is: it is made up of following each components in weight percentage: epoxide modified water soluble acrylic resin 45.0-55.0%, dispersion agent 0.3-0.5%, defoamer 0.25-0.45%, titanium dioxide 15-28.5%, pigment 0-6.3%, deionized water 3.25-14.7%, solubility promoter 7-8.5%, water soluble amino resin 9.0-11.0%.
Dispersion agent adopts acrylic dispersants.
Defoamer adopts polyethers to change surname type siloxane defoamer.
Titanium dioxide adopts Rutile type Titanium Dioxide.
Pigment is permanent yellow.
Solubility promoter adopts the mixture of propylene glycol monomethyl ether and 1-Methoxy-2-propyl acetate, and propylene glycol monomethyl ether content is 4.0-5.0%, and 1-Methoxy-2-propyl acetate content is 3-3.5%.
Its preparation method is:
At first prepare epoxide modified water soluble acrylic resin.Take into account in the stainless steel cauldron of steam heater having condenser, return channel, whipping appts, dropping still, temperature, squeeze into the water soluble acrylic resin earlier, slowly be warming up to 50 ℃, starting under the condition of stirring, dropping accounts for the small molecular weight Resins, epoxy (E-51) that the total amount weight percent is 7-11%, after fully stirring evenly, dropping accounts for the SILVER REAGENT Hypophosporous Acid, 50 that the total amount weight percent is 0.15-0.4%, slowly be warming up to 80 ℃ again, be incubated 2 hours down at 80 ℃ ± 2 ℃, cooling then detects qualified after-filtration packing.
Its performance index: solid content 50 ± 1%, second-order transition temperature-10 ± 1 ℃, outward appearance is that water-white is to light yellow viscous liquid.
The preparation method of epoxide modified water-soluble band tape paint:
At first in Scattered Kettle, add epoxide modified water soluble acrylic resin, under situation is started in stirring, add dispersion agent, defoamer, titanium dioxide, pigment, deionized water and solubility promoter successively at a slow speed, high speed dispersion was called in shredder and is ground after 45 minutes, after being ground to Xi Du ≦ 15 μ m, slurry is called in the paint still, add water soluble amino resin, after stirring evenly at a slow speed, the sampling censorship, qualified after-filtration packing.
Positively effect of the present invention is: its film performance of coating of the present invention has the high reaction activity of acrylic resin paint, strong adhesive force, shock resistance and the wear-corrosion resistance that weather resistance has epoxypaint again concurrently; Adopted lower organic solvent content in the prescription, nontoxic, more environmental protection, safer, physical and chemical performance reaches and is better than conventional solvent type product.
