AI Technical Summary

Problems solved by technology

At present, the concrete reinforcing agent used in the existing concrete materials has a single function, mainly to improve the early strength of concrete, and hardly contributes to the later strength, and does not help the concrete state
Especially in the sensitivity of the water reducing agent, the poor gradation of the sand and gravel materials, the concrete work defects caused by the large fluctuation of the mud content, and the water retention have no obvious effect.

Embodiment 1

[0038] Put 600 parts of deionized water, 3 parts of acrylamide, 2 parts of titanium sulfate, 0.2 parts of chromium propionate, 0.1 parts of potassium manganate, 1.2 parts of manganese acetate, 0.5 parts of nano-magnesium oxide, and 1.5 parts of magnesium glycinate into the stirring machine in sequence Stir and mix well in the reaction kettle, and raise the temperature to 40°C. After the temperature stabilizes, add 50 parts of maleic acid, 120 parts of hydroxyethyl methacrylate, 30 parts of HY-12D-7, and 10 parts of lauryl polyoxyethylene ether-9 to the above mixture and mix well. After mixing evenly, add 6 parts of sodium hypophosphite, 2 parts of basil, and 3 parts of ammonium persulfate in sequence, continue stirring for 15 minutes, then stop stirring, and let it stand for 1.5 hours to react. After standing still, add 1 part of titanate chelate, start stirring for 20 minutes, stop stirring, and cool to room temperature to obtain the concrete reinforcing agent.

Embodiment 2

[0040]820 parts of deionized water, 2 parts of acrylamide, 0.1 part of ammonium titanyl sulfate, 4 parts of chromium methionine, 0.8 parts of manganese sulfate, 0.4 parts of manganese methionine, 0.2 parts of manganese acetate, 0.1 parts of nano-magnesium oxide, and 1 part of magnesium acetate were pressed Sequentially put into the stirred reactor, stir and mix well, and raise the temperature to 42°C. After the temperature stabilizes, add 160 parts of methacrylic acid, 150 parts of methyl acrylate, 50 parts of hydroxyethyl acrylate, and 25 parts of HY-12D-8.6 into the above mixture and mix well. After mixing, add 3 parts of sodium hypophosphite, 0.02 parts of ferrous sulfate, and 2 parts of potassium persulfate in sequence, continue stirring for 10 minutes, then stop stirring, and let it stand for 2 hours to react. After standing still, add 3 parts of isopropyl tris(dioctylpyrophosphate acyloxy) titanate, start stirring for 25 minutes, stop stirring, and cool to room temperatu...

Embodiment 3

[0042] 700 parts of deionized water, 10 parts of acrylamide, 1 part of titanium sulfate, 2 parts of chromium picolinate, 0.5 parts of manganese sulfate, 0.4 parts of manganese acetate, 0.5 parts of magnesium nitrate, 0.5 parts of calcium magnesium salt, 0.2 parts of magnesium methionine Sequentially put into the stirred reactor, stir and mix well, and raise the temperature to 45°C. After the temperature is stable, add 40 parts of fumaric acid, 60 parts of acrylic acid, 100 parts of hydroxyethyl methacrylate phosphate, 50 parts of triisopropanolamine maleate, 10 parts of HY-12D-9 to the above mixture , 5 parts of nonylphenol polyoxyethylene ether and mix well. After mixing, add 12 parts of sodium methacrylate, 4 parts of sodium L-ascorbate, and 8 parts of hydrogen peroxide in sequence, continue stirring for 12 minutes, stop stirring, and let it stand for 1.5 hours to react. After standing still, add 5 parts of titanate coupling agent, start stirring for 20 minutes, stop stirri...

Abstract

The invention discloses a concrete reinforcing agent and a preparation method thereof. The reinforcing agent comprises 600-820 parts of deionized water, 50-160 parts of unsaturated acid, 80-200 parts of unsaturated ester, 2-10 parts of acrylamide, 5-40 parts of a nonionic surfactant and a proper amount of titanium salt, organic titanium, organic chromium, manganese salt, organic manganese, magnesium salt, organic magnesium, an oxidation component, a reduction component, a chain transfer agent and the like. The unsaturated acid, ester, acrylamide and organic titanium used in preparation have high activity, are polymerized or crosslinked in oxidation reduction, wrap the nonionic surfactant to form a net structure, and capture solid particles, so that the solid particles are fully combined with a water reducing agent, and the dispersity of cement particles is expanded. The organometallic compound is grafted into the polymer in a grafting manner, so that the cement strength is improved, and the supplemented titanium salt, magnesium salt, manganese salt and the like can help to utilize tricalcium silicate. The sensitivity of the water reducing agent can be reduced, the mixing performance is improved, the dosage is reduced, and the later strength and durability are ensured.

Description

technical field [0001] The invention relates to the field of concrete admixtures, in particular to a concrete reinforcing agent and a preparation method thereof, in particular to a concrete reinforcing agent capable of reducing the sensitivity of a water reducing agent, improving the construction performance of mixed concrete, reducing the amount of cement, and ensuring the later strength of concrete A highly adaptable concrete reinforcing agent for improving the long-term durability of concrete and a preparation method thereof.
