Water-based organic and inorganic composite coating and preparation method thereof
[technical field]
The present invention relates to paint field, tool is a kind of water-based organic and inorganic composite coating and preparation method thereof.
[background technology]
The Along with people's growth in the living standard, people increase the coating type demand gradually, and more pay close attention to the green environmental protection of product.Exterior wall and vault to cement-base concrete; Because its body of wall alkalescence is strong, humidity is high and hardness requirement is high; After the generic latex lacquer construction, be prone to that paint film adhesion is poor, hardness is low, the accumulation of salt in the surface soil, mildew and disadvantage such as be prone to peel off, be not suitable for the concrete base surface construction.
At present; The coating of domestic less suitable concrete base surface construction; Therefore develop that a paint film adhesion is good, hardness is high, water-fast, alkaline-resisting, temp. variation resistant, weathering resistance and the excellent coating of environmental-protecting performance, economic benefit will be very remarkable with environmental benefit, have wide application and development prospect.
[summary of the invention]
The objective of the invention is to solve the problem that above-mentioned prior art exists, a kind of excellent performance and water-based organic and inorganic composite coating that can save energy are provided.
Another object of the present invention provides a kind of preparation method of water-based organic and inorganic composite coating.
For achieving the above object, the technical scheme that the present invention adopts is: water-based organic and inorganic composite coating, to form by components such as base-material (water-soluble, film-forming material), pigment, filler, auxiliary agent and water, and it specifically is made up of the component of following parts by weight:
The label that said potassium silicate can select for use ocean, Xingtai chemical industry ltd to produce is the product of DY-403 or DY-404; The label of the production of Laiyang permanent letter chemical industry ltd is the product of HXY205 or HXY204, and perhaps the label of Jiangsu Guolian Technology Co., Ltd.'s product is the product of GHSK.
The label that said benzene emulsion can select for use BASF stock company to produce is distinguish the flavor of only emulsion or a 296D-S benzene emulsion of ECO502, the 998A emulsion of producing in the Foshan City Shunde District Batf Industry Co.,Ltd.
Said stablizer is a quaternary ammonium compound, the SPS that selects for use Clariant chemical industry (China) ltd to produce.
Said skimmer is a mineral oil defoaming agent, the SN-NXZ skimmer of selecting for use Nippon Nopco Assistant Co., Ltd. to produce.
Said dispersion agent is polycarboxylate sodium's class dispersion agent, and
that select for use Dow Chemical company to produce is prone to dispersion agent soon.
Said thickening material is a Mierocrystalline cellulose, preferably adopts Natvosol class thickening material, and the model that can select for use Akzo Nobel N.V. to produce is the thickening material of HS30000, and this thickening material and system compatible stability are good, stores the back stable viscosity.
Said frostproofer adopts terepthaloyl moietie, the terepthaloyl moietie that can select for use Guangzhou rich chemical industry in morning ltd to produce.The antifreeze efficient of this frostproofer is high, and cost performance is high.
Said film coalescence aid adopts 2,2,4-trimethylammonium-1, and 3-pentanediol-isobutyrate, the model of selecting for use Eastman Chemical to produce is the film coalescence aid of TEXANOL.
Said white titanium pigment adopts rutile-type, and the model of selecting du pont company production for use is the white titanium pigment of R-706.
Said coarse whiting adopts 800~1250 order coarse whitings, and the model that can select for use Switzerland Ou Miya group to produce is Omyacard 2 or Omyacard 5 coarse whitings.
Said talcum powder adopts 1000-1250 order talcum powder, the talcum powder that can select for use Heshan chemical industry (Liaoning) ltd to produce.
A kind of preparation method of water-based organic and inorganic composite coating, it step that comprises is following:
(1) pre-mixing: the water that in disperseing cylinder, adds 13~17 parts; And then add stablizer, dispersion agent, skimmer, film coalescence aid, frostproofer and the thickening material of above parts by weight respectively; Fully mix and form gelationus mixture, mix the rotating speed that stirs and be controlled at 300~500rpm;
(2) grind to disperse: in disperseing cylinder, add white titanium pigment, coarse whiting, the talcum powder of above-mentioned parts by weight, the grinding 20~25 minutes of under 1500~2500rpm, pulling an oar of control rotating speed, to fineness less than 50um;
(3) add filmogen: after in disperseing cylinder, adding benzene emulsion, stirring velocity is controlled at 1000~1500rpm, stirs; Add potassium silicate again, stirring velocity is controlled at 1000~1500rpm, stirs;
(4) add auxiliary agent: in disperseing cylinder, add remaining water successively, mix, mix the rotating speed that stirs and be controlled at 800~1200rpm, promptly get water-based organic and inorganic composite coating.
(5) packing: as requested coating is contained in the Lacquered Tin Plate Can of different volumes.
The present invention has used inorganic filming substance matter potassium silicate in coating, it adds back coating and has excellent alkali resistance, weathering resistance and thermotolerance, and heat resisting temperature can reach 500~600 ℃, and with inorganic substrate firm cohesive force is arranged; Have adjustable wet, antisweat property, hardness of paint film height.Moreover, because of water glass potassium silicate pH>13, make coating system not possess the bacterial growth environment, need not to add Antisepticize and mildew preventive, paint film has from anticorrosion antimildew function, thereby reduces product cost, has excellent environmental-protecting performance.In addition, the water glass potassium silicate is because its inherent characteristic as paint binder, has some shortcomings simultaneously, for example: poor water resistance, and it is hard and crisp, nonelastic, easy to crack to film, and bad with the viscosity of organic materials, and the paint film porous is so anti-permeability is poor.With synthetic resin emulsion as the compound use of inorganic base materials such as auxiliary film forming matter and potassium silicate; Organic resin can be filled in-Si-O-Si-reticulated structure gap in; Shield remaining hydroxyl, improve the paint film water tolerance, synthetic resins has elasticity preferably; Can improve the anti-cracking performance of paint film, and have snappiness preferably.Synthetic resin coating film is fine and close, can improve the paint film permeability resistance.After the compound use of inorganic silicic acid potassium and benzene emulsion, paint film adhesion is good, hardness is high, do not ftracture, water-fast, alkaline-resisting, temp. variation resistant, weathering resistance and environmental-protecting performance are excellent.Simultaneously, during the two compound use, the consistent stability that could guarantee mixed system on electrical property only, otherwise gelation and the creaming of emulsion of potassium silicate will occur and can not get stable coating.
With prior art contrast, the present invention has following advantage: hardness of paint film is high, does not ftracture, excellent weather resistance and hard, and paint film is more new lastingly; Do not add Antisepticize and mildew preventive, environmental-protecting performance is excellent, and the paint film repainted period is long, can economize on resources; In addition, product construction resistance is minimum, is prone to japanning, very easily promotes the use of.It has wide range of applications, applicable to applications such as vault, underground parking, interior wall and exterior walls.
