Example Embodiment

[0019] Example 1

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

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

[0022] The preparation method of modified montmorillonite powder in the above raw materials is: take the montmorillonite powder and grind it to a particle size of 20um in advance, then put all the ingredients into a heating pot, and then add 1 / 2 of the total amount of calcium carbonate. 3 times the total amount of montmorillonite powder is heated with stirring until the internal water content is 15%, and then a paste is obtained, which can be obtained by taking it out for high-temperature drying and grinding again.

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...
