Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, more specifically to a kind of be the macromolecule anticorrosion paint and preparation method thereof of main film forming substance by acrylic resin.
Background technology
Coating is a kind of easy construction, cheap, effect is obvious, value-added rates is high Chemicals.The surface that it not only has the building of making, boats and ships, machinery etc. prevents corrosion, the function that increases the service life, also have decorative environment to give the beautiful enjoyment or the function of eye-catching mark, along with the continuous development of science and technology, coating progressively becomes the strong fine chemistry product of a kind of specificity.
Existing widely used anticorrosion fluorine carbon lacquer has good antiseptic property, but there is following problem in it:
Problem one: construction requirement height.It need be formed by first and second pairs, and is now with the current at the construction field (site), and construction is subjected to time limitation, must use up in 10 hours, not so solidifies and then just can't use.
Problem two: for steel construction, anticorrosion surface layer processing requirements height.Before construction, must adopt sandblast thoroughly to eliminate rust scrub.Therefore, the use of anticorrosion fluorine carbon lacquer has limitation, can only be at new steel construction.
The widely used thermosetting powder coating(s) of existing another kind has good sticking power, snappiness, shock-resistance, gloss retention, weather resisteant, chemical resistance to reach good electrical apparatus insulation by force, but there is following problem in it:
Problem one: can only be in indoor spraying.Need be arranged on outdoor steel construction facility (as the isolation iron railing on the road etc.) and, must in factory, cut apart spraying, deliver to the working-yard assembling then if adopt thermosetting powder coating(s).If run into original, bulky, impartible or factory can not be processed the steel construction facility of combination, then thermosetting powder coating(s) can't use.So use thermosetting powder coating(s), it is new and old to be subjected to steel construction, and volume restriction big and little and that whether be easy to assemble can't be extensive use of.
Problem two: not energy-conservation.Thermosetting powder coating(s) need spray under certain temperature baking condition, and coating could become glue from the powder solid of doing, and baking-curing need consume a large amount of energy, does not meet the energy-conservation and requirement of saving enterprise cost that country advocates.
Therefore, be that corrosive gases such as strong alkali-acid resistance corrodes if can provide a kind of, construct again convenient, limited less, power consumption low new coating can the above-mentioned variety of issue of perfect solution.
Summary of the invention
One of purpose of the present invention is that coating in one will be provided, and promptly possesses the two advantage of anticorrosion fluorine carbon lacquer and thermosetting powder coating(s), can solve the problems referred to above of the two existence again.
Therefore, the present invention will solve following three technical problems:
Technical problem one: the erosion of etchant gases such as ability strong acid, highly basic;
Technical problem two: construction simply is not subjected to place, material, time limitation on the basis of the performance that possesses technical solution problem one;
Technical problem three: energy-conservation and environmental protection on the basis of the performance that possesses technical solution problem one and two.
Another object of the present invention provides a kind of preparation method of above-mentioned coating.
The present invention is the technical solution problem, selecting modification becomes hydrophilic, the acrylic resin of oleophylic dual nature, have acidproof, alkaline-resisting, water-fast, ageing-resistant, fire-retardant, do not contain benzene, formaldehyde chemical raw material and thinner, adopt chemical principle and coating physical reaction principle process combined flow process, through experiment repeatedly, develop a kind of macromolecule all-weather emulsion paint free coating, it is by filmogen, solvent, coatings additive(s) and face, filler is formed, and the weight percent of its moiety is: filmogen: solvent: coatings additive(s): face, filler=55%: 11%: 115%: 23%.It is characterized in that: filmogen is made up of profit two based acrylic resins, natural rubber, clorafin and Zinic stearas, and solvent is a Virahol.Selecting profit two based acrylic resins, natural rubber, clorafin and Zinic stearas for use is filmogen, at first is to utilize profit two based acrylic resin emulsive reaction mechanisms.Popular says, emulsification is oil-in-water, or water in oil process, like the candle in the combustion processes, lights up oil droplet in water, must condense immediately to float in the water.The coating of the present invention that clads through emulsification drips in the water and the candle oil droplet is same phenomenon in water, and therefore, product of the present invention can be met water and promptly be done, and has improved water tolerance, thereby has strengthened its acidproof, alkali resistance; Secondly, water-fast, acidproof, alkaline-resisting, attrition resistant performance that natural rubber has can increase the brightness of coating simultaneously again.That clorafin and Zinic stearas all have is fire-retardant, acid and alkali-resistance, self-cleaning characteristic, and Zinic stearas can also anti-aging.Selecting Virahol for use is solvent, be that to utilize Virahol be this characteristic of hydrophilic solvent, Virahol in the coating is slowly absorbed by water all around in water, in this process, oil that contains in the coating and fat, be not hydrophilic, just refuse water,, only allow running out of of Virahol so they can be compared to Yishanmen in water, never allow water to enter, water around the Virahol quilt has absorbed, and coating is also just from having done, thus, product of the present invention can soak from dried, thereby can improve its acidproof, alkali proof performance.In addition, Virahol does not contain benzene and formaldehyde, and is nontoxic and cheap, meets the social needs of health, environmental protection and economy.
The weight proportion of composing of the filmogen of this macromolecule anticorrosion paint is: profit two based acrylic resins: natural rubber: clorafin: Zinic stearas=45: 3: 3: 4.
The weight proportion of composing of the coatings additive(s) of this macromolecule anticorrosion paint is: defoamer: emulsifying agent: UV light absorber: coupling agent: wetting Agent for Printing Inks: flow agent=(2.5～3): (0.5～1): 5: (0.5～1): 1: 1.
The coatings additive(s) of this macromolecule anticorrosion paint defoamer on concrete the selection is a tributyl phosphate, and emulsifying agent is a silicone oil, and coupling agent is a titanate coupling agent, and wetting Agent for Printing Inks is a glycerine, and flow agent is a vinylformic acid.
The weight proportion of composing of the face of this macromolecule anticorrosion paint, filler is: titanium dioxide: fine particle calcium carbonate: the organosilicon cenosphere: toner=5: 10: 5: 3.
