Abstract
The invention discloses a high-performance sulfamic acid water reducing agent and a preparation method thereof. The high-performance sulfamic acid water reducing agent is prepared by the following raw materials in parts by weight: 6 to 20 parts of amino arylsulphonate, 4 to 8 parts of phenol organic matters, 1 to 5 parts of urea, 3 to 9 parts of carbolic oil, 7 to 15 parts of formaldehyde solution and 30 to 60 parts of water. The preparation method comprises the following steps of (1) placing the amino arylsulphonate, the phenol organic matters, the carbolic oil, the urea and the water into a reaction kettle to be mixed and dissolved, and keeping the temperature for 0.3 to 1h under the temperature of 60 to 80 DEG C; and (2) beginning to drop the formaldehyde solution, completing the dropping for 0.5 to 2h, increasing the temperature to 80 to 100DEG C to be maintained for 1 to 3h, and cooling down to obtain the high-performance sulfamic acid water reducing agent. The carbolic oil and urea with cheap price are adopted, so that the production cost of the high-performance sulfamic acid water reducing agent is reduced; and the water reducing rate is high, the workability of the concrete is good, the slump loss resistance is good, and the defects of high bleeding rate and easiness in isolation of concrete can be overcome.
Description
Technical field
The present invention relates to the water reducer field, particularly relate to a kind of high-performance Sulfamic acid water reducing agent and preparation method thereof.
Background technology
Along with the continuous progress of operating technique level, the building structure of high stratification, large span is more and more, requires concrete must possess high strength, high workability, high-durability, i.e. high performance concrete.And high performance concrete must use high efficiency water reducing agent.
The effect of high efficiency water reducing agent mainly contains: (1) improves its workability in the situation that maintenance mix water cement ratio is constant; (2) keeping under the constant prerequisite of workability, mixing water reducer the concrete unit consumption of water is reduced, improving concrete strength; (3) keeping using water reducer can reduce unit cement consumption under the constant prerequisite of concrete strength.
At present, have the amido sulfoacid series high-efficiency water reducer of development prospect both at home and abroad most, because production technique is simple, little loss of slump, its application is more and more extensive.Yet mainly there is following problem in the amido sulfoacid series high-efficiency water reducer that uses now: (1) cost of material is higher, to such an extent as to cause production cost higher; (2) bleeding rate is high, and concrete is easily emanated.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of high-performance Sulfamic acid water reducing agent and preparation method thereof, can effectively reduce the production cost of Sulfamic acid water reducing agent, overcomes simultaneously the shortcoming that bleeding rate is high, concrete is easily emanated.
