Water of the present invention is preferably deionized water.
The mechanism of action to instant component is further described through below:
1. the present invention is creatively by water-base epoxy technology and aqueous acrylamide technic acid composite usage, realizes two kinds of technologies Have complementary advantages, be obtained the excellent aqueous industrial coating product of antiseptic property, and assign new product with pot-life more long with it is very fast Rate of drying.
Aqueous epoxy coating has superior anti-corrosion of metal performance, is particularly well-suited to moderate anti-corrosion and heavy antisepsis field.Water Property epoxy coating be dual-component coating, i.e. component A and B component including being commonly called as in the industry.Come from existing domestic and international coating technology See, component A is mostly with amine epoxy hardener as base-material, and B component is then main construct with epoxy resin latex.Application is applied , it is necessary to component A is mixed with B component by certain weight ratio before work, and stir.As a rule, between A, B component Reaction is more violent, and drying varniss speed is faster, and pot-life is naturally shorter.Conversely, the reaction between A, B component is slower, activation Phase is more long, and drying varniss speed just accordingly slows down.
Water-borne acrylic coatings have rate of drying faster, and component is single, easy to operate, can be voluntarily under normal temperature condition Drying and forming-film.Present invention research finds, water-based acrylic resin is compounded by a certain percentage with epoxy hardener, with obtained in it Coating component A is used after mixing with B component, both can significantly extend pot-life, and can maintain drying and forming-film speed quickly.
Water-base epoxy technology and the composite usage of aqueous acrylamide technic acid, can retain the strong anti-corrosive properties of water-base epoxy technology On the premise of energy, the perfect adaptation of pot-life more long and very fast rate of drying is realized, be the industrialization application of water-based anticorrosive paint Bring good operability.
2. it is blending resin with water-based acrylic resin and aqueous amine curing agent resin, by formulation optimization, determines two Optimal proportion of the resin in novel epoxy coating component A is planted, fundamentally ensures the remarkable anti-corrosion of aqueous industrial anticorrosive paint Performance, faster drying varniss speed and pot-life more long.
For bi-component aqueous epoxy coating system, there are the amine hardener of three quasi-representatives, i.e. aliphatic firming agent, acid amides Class curing agent, alicyclic curing agent.Three class curing agent respectively have its advantage and defect.Aliphatic amine curing agent has fast reaction speed Degree, good adhesive property and moderate pliability, but unmodified fatty amine has certain penetrating odor;Amide-type curing agent paint is attached Put forth effort that good, pliability is good, non-stimulated smell, but its reaction speed is lower slightly, hardness is not good enough;The working life of cycloaliphatic amines curing agent fits When, chemical-resistant is good, hardness is high, but pliability is poor, is unfavorable for improving the impact resistance of coating.Preferably U.S.'s cyanogen of the invention is special The modified aliphatic amine hardener BECKOPOX EH 613w of company's production are curing agent resin, and it has reaction speed faster Degree, stronger adhesive force and excellent environmental protection characteristic.
The acrylic emulsion RS-719F of preferably Ahmedabad richness Industrial Co., Ltd. of the invention production is compounding resin.RS-719F A kind of polymer of acrylic ester copolymer, with particle is tiny, modest viscosity the characteristics of, with antirust agent, rust resisting pigment Compatibility is good, has excellent adhesive force with its made product and metal base, water-fast, salt spray resistance, alkaline-resisting excellent.
In blending experimental formula is carried out to water-based acrylic resin and aqueous amine curing agent resin, present invention research hair Existing, the weight proportion of water-based acrylic resin and aqueous amine curing agent resin directly affects coating pot-life, drying in itself The physical and chemical performance of speed and paint film;When water-based acrylic resin and aqueous amine curing agent resin are in formulation for coating material When weight proportion is 10~12, the water-based industrial paint product of paint film excellent combination property can be obtained.
3. the selection of aqueous epoxy resins and the optimization of consumption
The design of aqueous epoxy coating B component formula, finally determines crosslinking degree and the reaction of two component epoxy coating Speed, and directly affect the performance of paint film.Epoxy resin of the preferably Guangdong sea of the invention along the production of new material Science and Technology Ltd. HMP-2255, the water-base resin epoxide number is high, viscosity is low, lighter color, and environment-friendly advantage substantially, can be widely used for all kinds of metal substrates Anti-corrosion, it can also be used to binding agent, solventless coatings and aqueous floor coatings etc..
The weight ratio of aqueous epoxy resins and amine curing agent in component A in B component is precisely controlled, is aqueous epoxy coating One of core link of formulation optimization.Aqueous epoxy resins content is high, and crosslinking rate is very fast, but is easily caused the pot-life of product Shorten;Aqueous epoxy resins content is low, and the pot-life of product can extend, but crosslinking rate is slower, is easily caused drying varniss It is too slow.Furthermore, aqueous epoxy resins content is too low or too high, may all cause cross-linking reaction not exclusively, under causing hardness of paint film Drop, or even paint film cannot be dried really.
Present invention research finds, when aqueous epoxy resins HMP-2255 additive capacities and aqueous amine curing agent When the weight ratio of HBECKOPOX EH 613w is 12%~14% (percentage by weight), water-base epoxy metal anti-corrosive paint component A It is 100 with the weight ratio of B component:(35~45).Double-component aqueous metal anti-corrosive paint product under this conditions of mixture ratios, has Pot-life, faster rate of drying and more excellent paint film combination property more long.
4. the cause of water corrosion-resistant epoxy paint paint film is strengthened with color stuffing and addition functional environment-friendly rust resisting pigment by level Density, improves the antirust, anti-corrosive performance of paint film, and further lifts the physical and mechanical property of paint film.
In the component A formulation composition of water corrosion-resistant epoxy paint, color stuffing plays the left and right of skeleton, different color stuffings There are different particle diameters and mode of appearance.If the color stuffing of different-grain diameter arranged in pairs or groups mixing in appropriate proportion, it is dispersed in In the component A of aqueous epoxy floor paint, it is well mixed when with component B epoxy resin, after reaction solidification, bead filling can be formd In the relatively compact state of big ball.
The color stuffing used in formula have titanium dioxide, talcum powder, calcium carbonate superfine powder, sericite in powder, etc..In view of various face Actual efficacy of the filler in the middle of formula, thickness level is carried out to it with collocation, and the additional proportion of each component is adjusted to most It is good, it is ensured that the consistency after paint film film forming.
