Abstract

The invention provides a high performance water-reducing agent of sulfanilate-sulfonated acetone-formaldehyde condensate and process for preparation, wherein the water reducing agent water, p-aminobenzene-sulfonic acid or sulfanilate, sodium sulfite or sodium metabisulfite, acetone and methyl aldehyde, or charging water-keeping component, retardation component or gas guiding component, finally obtaining the liquid product through stirring homogeneously.

Description

Sulfanilate-sulfonated acetone-formaldehyde condensation products high efficiency water reducing agent and preparation method thereof
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 is that to utilize Sulphanilic Acid (salt), sulfurous acid (hydrogen) sodium, acetone and formaldehyde be a kind of high efficiency water reducing agent with high water reducing rate of feedstock production.
The purpose of this invention is to provide a kind of concrete high efficiency water reducing agent, this product is liquid or the powder-like product that utilizes industrial chemicals polynary condensation of process and processes such as physics is compound, drying treatment to make.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.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:
1, sulfanilate-sulfonated acetone of the present invention-formaldehyde condensation products high efficiency water reducing agent and preparation method thereof is: the water of getting the 40-300 weight part, add the aniline sulfonic acid (salt) of 20-100 weight part and sulfurous acid (hydrogen) sodium of 20-100 weight part, the acetone that adds the 20-200 weight part, after being elevated to certain temperature sulfonation for some time, the formaldehyde that slowly adds the 20-200 weight part, reacted at a certain temperature 2-8 hour, product liquid can be obtained, also drying treatment powdering product can be passed through.
2, sulfanilate-sulfonated acetone of the present invention-formaldehyde condensation products high efficiency water reducing agent can also be to add water-retaining component, bleed component and slow setting component after obtaining liquid product again, obtains having the product of different performance; Or after drying obtains powder-like product, add 0-2 again and divide water-retaining component, 0-2 gram bleed component and 0-5 gram slow setting component, obtain having the powder-like product of different performance after machinery is compound.
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.
Specific implementation method:
Example 1
At first be that 300 water that restrain and 46 gram Sodium sulfanilates and 38 gram S-WAT inputs have in the there-necked flask of condenser with weight, add 58 gram acetone, be warmed up to 56 ℃, sulfonation began to drip 37% formaldehyde, 160 grams after 1 hour, controlled temperature, make add formaldehyde after temperature slowly rise to 94 ℃, insulation reaction 6 hours obtains liquid product, solid content is 26%, can get powder-like product through further drying.
Example 2
At first be that 300 water that restrain and 34 gram Sulphanilic Acid (crude product) and 30 gram sodium bisulfite inputs have in the there-necked flask of condenser with weight, neutralize with sodium hydroxide, adjust pH value to 12, add 58 gram acetone, be warmed up to 56 ℃ of sulfonation then after 1 hour, begin to drip 37% formaldehyde, 160 grams, controlled temperature, make add formaldehyde after temperature slowly rise to 94 ℃, insulation reaction 6 hours, obtain liquid product, solid content is 26%, and adding 5 gram tripoly phosphate sodium STPPs, 1 gram colophonium pyrolytic polymer, 1 gram methylcellulose gum obtain efficient retarding and water reducing agent.
Below use its effect of description of test of Sulphanilic Acid class-sulfonated acetone of the present invention-formaldehyde condensation products high efficiency water reducing agent
