Said material canb e mixed with the invented powder preparation, and in which the high-grade cement and mid-sand are added, then those can be made into an aqueous emulsion type mixed anti-corrosion and anti-rust mortar. Said invention is low in cost, and has the good stability and construction properties.
Description
The present invention relates to be used to protect skeleton construction in order to avoid the impregnating material that is damaged by corrosion is specifically related to a kind of aqueous-emulsion type co-mixed anti-corrosion anti-rust material mortar and manufacture method thereof.
The normal swelling owing to the external corrosion medium of the skeleton construction of industry and civil building corrodes, or steel bar corrosion generation concrete cracking behind the harmful ion intrusion concrete, peels off serious threat safety of whole building thus and weather resistance.In order to avoid be damaged by corrosion, some impregnating material have appearred in succession on market in order to protect reinforced concrete buildings.These impregnating material are used to protect reinforced concrete buildings can play certain antiseptic and rustproof effect, but there is following problem in they taken as a whole: 1) batch poor stability, and workability is not good; 2) price is higher; 3) only focus on single antiseptic property, antiseptic and rustproof over-all properties is noted inadequately; 4) package stability is relatively poor.
In order to overcome the problems referred to above of existing Steel Concrete impregnating material, therefore the object of the present invention is to provide a kind of anti-corrosion anti-rust material, mortar and manufacture method thereof that is used for skeleton construction, the batch of its finished product stability and having good workability, cost is lower than like product, can be anticorrosion all sidedly and antirust and effect is remarkable, easy construction and storage and transportation stability are good.
Above-mentioned purpose of the present invention is achieved like this, promptly obtain a kind of aqueous-emulsion type co-mixed anti-corrosion anti-rust material by development, the emulsion that it is made up of following ingredients at least: the water of 40 to 80 weight quota, the polymer emulsion of 50 to 160 weight quota, the polyvinylacetal tackiness agent of 20 to 100 weight quota, the thickening material of 5 to 16 weight quota, the antiseptic and rustproof auxiliary agent of 1 to 14 weight quota and the defoamer of 0.5 to 3 weight quota.
Resulting emulsion can be used as the anti-corrosive protecting agent that is applied to concrete surface; also can be used: the light filler of 70 to 100 weight quota with the pulvis of following component; the nitrite of 10 to 30 weight quota; 0.5 phosphoric acid salt to 14 weight quota; 0.3 vitriol to 11 weight quota; 0.1 to the urotropine of 6 weight quota, the stablizer of 1 to 5 weight quota, the powdery oxygen absorbent of the water reducer of 0.3 to 10 weight quota and 0.01 to 2 weight quota.
Polymer emulsion in above-mentioned anti-corrosion anti-rust material is the ethene-vinyl acetate copolymer emulsion, benzene emulsion, ACRYLIC EMULSION, a kind of in the neoprene latex or two or more blend wherein.
The manufacture method of above-mentioned aqueous-emulsion type co-mixed anti-corrosion anti-rust material of the present invention is: get the ethene-vinyl acetate copolymer emulsion in advance, benzene emulsion, ACRYLIC EMULSION, a kind of polymer emulsion in the neoprene latex or the weight quota of the blending emulsion 50 to 160 of two or more polymkeric substance wherein, and in advance with the water of 40 to 100 weight quota, the polyvinylacetal tackiness agent of 20 to 100 weight quota, the thickening material of 5 to 16 weight quota, the antiseptic and rustproof auxiliary agent of 1 to 14 weight quota and the miscible one-tenth miscible fluid of the defoamer of 0.5 to 3 weight quota, then described polymer emulsion and described miscible fluid are injected reactor, and adopt at the uniform velocity high shear force whipping appts stirring therein, obtain the emulsion product after mixing.
With above-mentioned emulsion, pulvis, 425
#The cement of above label and GB medium sand compare with weight quota: 30-50: 515: 40-60: 100-150 mixes, and makes the aqueous-emulsion type co-mixed anti-corrosion anti-rust mortar, also can add microlith when needing, and is used for concrete construction.
Owing in aqueous-emulsion type co-mixed anti-corrosion anti-rust material of the present invention and mortar, added the polyvinylacetal binder constituents, made this material have good especially antiseepage effect; Adding thickening material in the material increases the stability of emulsion; And the adding powdery stabilizer can make pulvis wherein be difficult for moisture absorption caking in the material.
Owing to used the prescription and the method for the invention described above, this kind aqueous-emulsion type co-mixed anti-corrosion anti-rust material and mortar are compared with some at present commercially available like products, and have following advantage: (1) antiseptic and rustproof performance is comprehensive, and effect is remarkable; (2) the material comprehensive cost descends about 40% than like product; (3) easy construction, the good stability of storing and transporting; (4) manufacture method advanced person can be fit to suitability for industrialized production, and the constant product quality of producing is good; (5) early strength is big, can reduce curing time.
