Abstract
The invention discloses a sulfamic acid series water reducing agent and belongs to the field of chemical engineering. The sulfamic acid series water reducing agent is composed of 20-40 parts of phenol, 25-50 parts of anhydrous p-Aminobenzene sulfonic acid, 8-15 parts of urea, 80-120 parts of formaldehyde, 0.08-0.12 part of concentrated sulfuric acid and 20-40 parts of sodium hydroxide. According to the sulfamic acid series water reducing agent, a synthesis reaction does not need an air entraining agent, production cost is greatly lowered, the degree of the reaction is large, and dispersibility of concrete is good.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of aminosulfonic water-reducing agent
Background technology
The kind of concrete admixture is a lot, divide by function have water reducer, air entraining agent, antifreeze,
Extender, waterproofing agent etc., the concrete admixture used in Practical Project has the most simultaneously
Multiple functions, or multiple additive is used simultaneously.And Japan is to concrete admixture at present
Only it is divided into four big class air entraining agents, water reducer, gas tracting subtractive agent and efficient gas tracting subtractive agent.Wherein,
Most widely used with water reducer, and have different division mode classifications.
Aminosulfonic water-reducing agent belongs to single aromatic ring type water reducer, refers mainly to polymer hydrophobic master
Chain is alternately formed by connecting by phenyl and methylene, and can be connected to a SO on the monocycle of main chain3H、
One OH, a NH2With the hydrophilic functional groups such as a COOH, the substituent group such as alkyl, alkoxyl,
Or there is a possibility that being connected to the long chain alkyl group such as polyoxyethylene groups on main chain makes the type water reducer have
Comb-type structure as polycarboxylic-acid.
Summary of the invention
For above-mentioned, it is an object of the invention to provide a kind of aminosulfonic water-reducing agent
The concrete technical scheme that the present invention takes is:
A kind of aminosulfonic water-reducing agent, it is characterised in that by weight, by following raw material group
Become: phenol 20-40 part, anhydrous p-aminobenzene sulfonic acid 25-50 part, carbamide 8-15 part, first
Aldehyde 80-120 part, concentrated sulphuric acid 0.08-0.12 part, sodium hydroxide 20-40 part.
Present invention also offers the manufacture method of a kind of aminosulfonic water-reducing agent, including following step
Rapid:
(1) weigh phenol and p-aminobenzene sulfonic acid in proportion in flask, add appropriate hydrogen-oxygen
Changing sodium solution makes it be completely dissolved, and test solution pH value makes its value more than 10；
(2) flask is installed on reaction frame, adds condensation reflux unit.Formalin
Add in constant pressure funnel, at the uniform velocity instill in flask, start simultaneously at heated and stirred, constant temperature
80 DEG C are reacted 4 hours；
(3) stopped reaction when reactant liquor color is rufous in flask, is cooled to room temperature
PH=7-8 is regulated afterwards with sodium hydroxide.
The invention have the advantage that synthetic reaction is not required to use air entraining agent, greatly reduce and produce into
Originally, and reaction carries out degree relatively greatly, preferable to the dispersibility of concrete.
