Abstract
The present invention relates to a high-efficiency water-reducing agent of a sulfanilate-vulcanizatio acetone-formaldehyde condensation product and a preparation method thereof. The high-efficiency water-reducing agent is characterized in that the high-efficiency water-reducing agent is synthesized by using water, sulfanilic acid or sulfanilate, sulfite or hydrogen sodium or sodium metabisulfite, acetone and formaldehyde as main raw materials which can also be added with a water holding component, a retardation component and an air entraining component to be uniformly stirred, and a liquid product is obtained; a powder product can be obtained under the condition that the liquid product is dried, and the water holding component, the retardation component and the air entraining component can also be added after the liquid product is dried into the powder product. The water-reducing agent has the advantages of low alkali content, simple production, short producing cycles, low cost, no production waste generation, low mixed amount, high water reducing rate and small slump constant loss; furthermore, the high-efficiency water-reducing agent can solve the problem of faster loss of the concrete viscosity influenced by temperature factors. The high-efficiency water-reducing agent is a novel variety after sulfamate and fatty group high-efficiency water-reducing agents.
Description
Technical field
The present invention relates to high efficiency water reducing agent, dispersion agent and the production technical field of concrete and mortar.The present invention more specifically utilizes Sodium sulfanilate, sulphonating agent, acetone and the formaldehyde a kind of high efficiency water reducing agent with high water reducing rate for feedstock production.
Background technology
Sulfonated acetone-formaldehyde condensation products is a kind of oil well cement dispersion agent of excellent property, and its effect in the reinforcing oil well operation is proved.Sulfonated acetone-formaldehyde condensation products begins as concrete high efficiency water reducing agent after nineteen ninety.Its distinguishing feature is can reach the intensive dispersion effect under the very little situation of consumption, not bleed, and slow setting is not particularly useful for using under the temperature conditions of higher, and its shortcoming is, and is relatively poor with the concrete slump maintenance of its preparation.
Summary of the invention
The purpose of this invention is to provide a kind of concrete high efficiency water reducing agent, this product is the liquid product that utilizes industrial chemicals to make through polynary condensation.After reaction mass adds during production, only need be heated to 50-60 ℃, liberated heat both can have been kept and be reacted to terminal point when adding formaldehyde, can save a large amount of energy.This reaction pair equipment requirements is not high, can save great amount of investment.Easy and simple to handle, with short production cycle, no waste material produces, and scale is changeable.Sodium sulfanilate-sulfonated acetone of the present invention-formaldehyde condensation products high efficiency water reducing agent water-reducing rate height, water-reducing rate can be up to 20-35%, and the slump of Cement Concrete is very little internal loss in 1-2 hour.
Task of the present invention is achieved through the following technical measures:
Sodium sulfanilate-sulfonated acetone of the present invention-formaldehyde condensation products high efficiency water reducing agent preparation method is: the water of getting the 40-300 weight part, add the sodium sulfanilate of 20-100 weight part and the S-WAT of 20-100 weight part, the acetone that adds the 20-200 weight part, after being warmed up to 30-60 ℃ of sulfonation 0.5-2 hour, the formaldehyde that slowly adds the 20-200 weight part, reacted 2-8 hour down at 80-100 ℃, can obtain product liquid.
The advantage that the present invention is compared with prior art had:
1, this water reducer has very high water-reducing rate, and its outstanding feature is: under very low water cement ratio, concrete still has good flowability, and slump-loss is little, and the diminishing enhancement is remarkable, is particularly useful for preparing high performance concrete.
2, technology of the present invention is simple, and raw material sources are extensive, and price is low.
3, not tight to the production unit requirement, less energy consumption, less investment, environmentally safe.
