Problems solved by technology

[0004] Due to its actual performance, concrete is more crispy. Therefore, when using glue for bonding steel, it is easy to cause the whole piece to fall off after bonding, resulting in extremely poor bonding effect and affecting the actual bonding performance. Traditional When the steel glue is used, it cannot meet the routine use of concrete. The stress effect after bonding is poor, and the effect of use is not obvious.

Embodiment 1

[0020] A steel glue for concrete is prepared from the following raw materials:

[0021] 60kg of epoxy resin, 5kg of furfural, 3kg of acetone, 5kg of triethylenetriamine, 10kg of cement, 5kg of crushed stone powder, 6kg of silicon micropowder, 5kg of acidified castor oil, 6kg of ammonium lignosulfonate, 1kg of ethylene glycol butyl ether, dimethyl Sulfoxide 5kg, talc powder 5kg, modified montmorillonite powder 5kg, deionized water 75kg;

[0022] The preparation method of the modified montmorillonite powder in the above raw materials is as follows: take the montmorillonite powder and grind it in advance until the particle fineness is 20um, then put all the ingredients into the heating pot, then add 1 / 2 of the total amount of calcium carbonate, and then add The clear water which is 3 times the total amount of montmorillonite powder is heated while stirring until the internal moisture content is 15% to obtain a paste material, which is taken out and dried at high temperature, and ...

Embodiment 2

[0029] A steel glue for concrete is prepared from the following raw materials:

[0030] 70kg of epoxy resin, 6kg of furfural, 4kg of acetone, 6kg of triethylenetriamine, 11kg of cement, 6kg of crushed stone powder, 7kg of silicon micropowder, 6kg of acidified castor oil, 7kg of ammonium lignosulfonate, 2kg of ethylene glycol butyl ether, dimethyl Sulfoxide 6kg, talcum powder 6kg, modified montmorillonite powder 6kg, deionized water 80kg;

[0031] The preparation method of the modified montmorillonite powder in the above raw materials is as follows: take the montmorillonite powder and grind it in advance until the particle fineness is 30um, then put all the ingredients into the heating pot, then add 1 / 2 of the total amount of calcium carbonate, and then add The clean water which is 3 times the total amount of montmorillonite powder is heated while stirring until the internal moisture content is 25% to obtain a paste material, which is taken out and dried at high temperature, an...

Abstract

The invention discloses sticky steel glue for concrete. The sticky steel glue is prepared from the following raw materials in parts by weight: 60 to 80 parts of epoxy resin, 5 to 7 parts of furfural,3 to 5 parts of acetone, 5 to 7 parts of triethylene triamine, 10 to 12 parts of cement, 5 to 7 parts of macadam powder, 6 to 8 parts of silica powder, 5 to 7 parts of acidified castor oil, 6 to 8 parts of ammonia lignosulphonate, 1 to 3 parts of ethylene glycol monobutyl ether, 5 to 7 parts of dimethyl sulfoxide, 5 to 7 parts of talcum powder, 5 to 7 parts of modified smectite powder and 75 to 85parts of deionized water. The sticky steel glue has the beneficial effects that the processing process is simple, scientific and standardized, and the formula is reasonable; when being used in the concrete, the prepared sticky steel glue has a remarkable curing effect, superior permeability, high bonding performance and remarkable application effect.

Description

technical field [0001] The invention relates to the technical field of adhesive processing, in particular to a steel adhesive for concrete and a preparation process thereof. Background technique [0002] Adhesive to steel, with super strong adhesive force, strong shearing force, anti-aging, good medium resistance (acid, alkali, water), strong impact resistance, normal temperature curing, small shrinkage during hardening, no flow during construction, no Volatile solvent, non-toxic and convenient construction, it can be applied in a wide temperature range without precipitation, and it is suitable for almost all building substrates. [0003] Structural glue for bonding steel is in the form of paste, with thinner state and good thixotropy. It is mainly used for bonding reinforcement of concrete components, masonry components and steel components to steel plates, curtain wall installation; bonding installation of marble, granite, ceramic tiles, etc.; Surface repair and bonding o...
