Abstract
The invention discloses a high-performance inorganic coating which comprises 35 to 42 percent of silicic acid sodium carbonate, 3 to 7 percent of emulsion, 32 to 40 percent of pigment and filling agent, 6 to 10 percent of water and 4.4 to 10 percent of additive agent by weight percentage. When being coated on the concrete surface, the silicate modified compound based coating can easily penetrate into the interior through concrete gaps for completing chemical curing reaction with calcium hydroxide (essential component of concrete), thereby not only making up the defect caused by using organic substance based emulsion adhesive, but also changing the physical and chemical characteristics of the commonly used water-borne inorganic coating. Compared with the conventional inorganic coating, the coating of the invention has good storage stability, improved strength and accelerated weatherability.
Description
Technical field:
The present invention relates to a kind of inorganic paint, particularly a kind of inorganic paint with good adhesion, weathering resistance, wear resistance, thermotolerance, static resistance.
Background technology:
In order to improve the weathering resistance of building wall and other objects, erosion resistance and chemically resistant material etc., generally all need be coated with and coat on its surface, and coating commonly used at present is organic coating, promptly be the based coating composition or be that the based coating composition whitewashes with the styrene-acrylate milk sap of modified by vinyl with the styrene-acrylate, although it is good that these coating have cohesiveness, preservative property are good, but because its main component is an organism, and these organism are generally all malicious, environment and HUMAN HEALTH are exerted an influence, therefore existing problems aspect security are used more and more to be restricted.
These problems of organic coating as long as its main component is an organism, just can't solve, so people have forwarded research emphasis on the inorganic aqueous coating to.Because aqueous inorganic paint commonly used has bad adhesion, therefore the shortcoming of easily aging and rustless property difference is used to be restricted, and is badly in need of the inorganic paint that the exploitation tackiness is good, be difficult for aging and good antirust property.Existing inorganic aqueous coating, as Chinese invention patent application 99112951.2 disclosed a kind of aqueous inorganic paints, mainly by silica sand, the glass slag, blast furnace slag, cement, slag, in pottery renewable resource inorganic powder such as slag and the volcanic ash 1,2 kinds is main material, with cement is auxilliary material, this coating of adding water soluble organic system tackifier powder constituent again, though this invention has reached the purpose of utilizing renewable resource or utilization of waste material, product does not have any pollution, higher weather resistance is arranged, waterproof and dampproof, protection against corrosion, strong adhesion, difficult drop-off, be difficult for and external environment factor generation chemical reaction, harmless, but because its prescription that provides is inconsistent, can't reach the performance that it is declared, therefore can't practical application.
Summary of the invention:
A kind of high-performance inorganic coating that purpose of the present invention just provides, with silicate modified compound is that based coating is easy to when being coated on concrete surface infiltrate by the concrete space inner, finish chemical curing reaction with calcium hydroxide (concrete main component), both remedy the defective of using based on organism that emulsion binding agent was produced, changed the physical and chemical performance of aqueous inorganic paint commonly used again.
The object of the present invention is achieved like this: a kind of high-performance inorganic coating, containing weight percent is the silicic acid yellow soda ash of 35-42%, the emulsion of 3-7%, pigment and weighting agent, the water of 6-10% and the additive of 4.4-10% of 32-40%.
Described emulsion and silicic acid yellow soda ash make this coating that better physicals and chemical property be arranged by modified-reaction, if the weight ratio of silicic acid yellow soda ash is lower than 35%, the intensity of coating reduces, and surpasses 42% weight ratio and work as consumption, and coating becomes fragile easily.
When the consumption of described emulsion is lower than 3% weight ratio of described inorganic paint gross weight, apply operating efficiency and reduce, and inorganic coating can produces bleaching phenomenon or initial water tolerance reduces.When the consumption of described emulsion surpasses 7% weight ratio, described inorganic coating composition reduces the infiltrative physicals of concrete material, and air permeability descends, thereby dope layer is expanded.
Described pigment is titanium dioxide, and its content is the 17-28% weight percent.
Described weighting agent comprises kaolin, zinc sulfide white and aluminum oxide, and their content is the 4-5% weight percent.
When described pigment and weighting agent weigh less than this coating weight ratio 32% the time, the coating whiteness descends, the coating covering effect reduces, and when weight overweight ratio 40% the time, coating is firm inadequately, and viscosity, operating efficiency, water tolerance and stability in storage significantly descend, in addition, in quickening the weathering resistance test, the surface portion of coating is polluted by pigment and analogue thereof easily and causes powder phenomenon-tion.
Described additive comprises wetting agent, propylene glycol, wilkinite, film coalescence aid, thickening material, defoamer and PH conditioning agent, and their content is respectively 1-2%, 1-3%, 1-2%, 0.5-1%, 0.5-1%, 0.2-0.5% and 0.2-0.5% weight percent.
Described wetting agent is the mixture of phosphoric acid solution and quaternary ammonium solution.
Described defoamer is Tego-810.
Described thickening material is a Natvosol.
The present invention compared with prior art has following advantage:
With silicate modified compound is that based coating is easy to when being coated on concrete surface infiltrate by the concrete space inner, finish chemical curing reaction with calcium hydroxide (concrete main component), both remedied the defective of using based on organism that emulsion binding agent was produced, changed the physical and chemical performance of aqueous inorganic paint commonly used again, compare with the inorganic paint of routine, have good preservation stability and the intensity of improving and quicken weathering resistance.
