Description
Technical field
The present invention relates to a kind of synthetic resin coating and preparation method thereof, more specifically to a kind of be the coating for internal and external wall 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 water-borne coatings (as the water-based Nippon), solvent reducible coatings (as elastomeric propylene acid coating) performance is common, has following defective:
Defective one: not being stained with property and water-repellancy, non-setting adhesive, chemical glue are pasted and are peeled off difficulty after (as be found everywhere be affixed on " black small advertisement " on the buildings such as electric pole) gets on, free ink pen is write and can't be wiped later, influences attractive in appearance and to clean intensity big;
Defective two: resistance to acids and bases is not strong, and antiseptic property is not high, thereby the not corrosion of anti-various chemical gas, run into the chemical gas run, drip, leak, gently then peeling comes off, and is heavy then cause the metope concrete pedestal loose, cause security incident, use in the factory building workshop that is not suitable for chemical enterprise;
Defective three: because of its water-repellancy is not strong, and can not meets water and promptly do, soak in water from doing, so the construction weather condition are had particular requirement: can not rain in 2 o'clock in the construction front and back, cause the inconvenience in the construction.
Therefore, if can provide a kind of is not stained with, waterproof, acidproof, alkaline-resisting, the coating of easy construction can thoroughly address the above problem.
Summary of the invention
One of purpose of the present invention is to solve following three technical problems:
First technical problem that the present invention will solve be to provide a kind of and not be stained with, the coating of waterproof, can complete peeling off after reaching non-setting adhesive, chemical glue and sticking, free ink pen is write the effect that water wiping later can be clean, make city cleaning, attractive in appearance, and reduce the cleaning worker working strength significantly, to solve aforementioned disadvantages one.
Second technical problem that the present invention will solve is that a kind of acidproof, alkali proof protective system will be provided simultaneously, makes factory building, workshop durable in use, to solve aforementioned disadvantages two.
The 3rd technical problem that the present invention will solve is to provide a kind of water-fast simultaneously, can meet water and promptly do, soak in water from dried, thus the coating of the round-the-clock use of energy, to solve aforementioned disadvantages three.
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, has acid and alkali-resistance, water-fast, ageing-resistant, fire-retardant, the chemical raw material of viscosity not, and the coatings additive(s) of profit dual-purpose, adopt the technological process of pigment dyestuff and the two unification of coating, through experiment repeatedly, develop a kind of like this 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=47%: 18%: 9.5%: 25.5%.It is characterized in that: filmogen is made up of profit two based acrylic resins, natural rubber, paraffin and stearic acid, and solvent is a Virahol.Selecting profit two based acrylic resins for use is to utilize its emulsive reaction mechanism.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 coats 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.In the process of development, the degree that water oil coats is decided according to the shape of coatingsurface polywater Cheng Zhu.Improved the water tolerance of product, thus its acidproof, alkali resistance of corresponding enhancing; Secondly, water-fast, acidproof, alkaline-resisting, attrition resistant performance that natural rubber has can increase the brightness of coating simultaneously again.That paraffin and stearic acid all have is fire-retardant, acid and alkali-resistance, the characteristic of not being stained with.Selecting Virahol for use is solvent, is that to utilize Virahol be this characteristic of hydrophilic solvent, the Virahol in the coating in water by around water slowly absorb, in this process, oil that contains in the coating and fat are not hydrophilic, just refuse water, so they can be compared to Yishanmen in water, only allow running out of of Virahol, never allow water to enter, when Virahol has been absorbed by water on every side, coating is also just from having done, and therefore, product of the present invention can soak from doing.In addition, Virahol 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 all-weather emulsion paint free coating is: profit two based acrylic resins: natural rubber: paraffin: stearic acid=40: 1: 3: 3.
The weight proportion of composing of the coatings additive(s) of this macromolecule all-weather emulsion paint free coating is: defoamer: emulsifying agent: UV light absorber: static inhibitor: coupling agent: wetting Agent for Printing Inks: flow agent=4: 1: 1: (0.5～1): (0.5～1): (1～1.5): (0.5～1).
The coatings additive(s) of this macromolecule all-weather emulsion paint free coating 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 all-weather emulsion paint free coating, filler is: titanium dioxide: fine particle calcium carbonate: the organosilicon cenosphere: aqueous color paste=12: 8: 5: 0.5.
