Abstract
The invention discloses a manufacturing method of polycyclic aromatic sulfonate polymer concrete dehydragent in the chemical manufacturing technique, which is characterized by the following: adopting anthracene slag and condensed sulfuric acid as raw material; sulfonating under 70-120 deg.c; hydrolyzing; condensing; neutralizing; improving receiving rate effectively.
Description
Technical field
The present invention relates to the production technique of a kind of production process of chemical product, particularly cement water reducing agent.
Background technology
The production craft step of existing cement water reducing agent is sulfonation, hydrolysis, condensation, neutralization, but the sulfonation raw material that adopts is the carbolineum and the vitriol oil, because a large amount of compositions are anthracene in the carbolineum, the sulfonation temperature condition is 130 ℃, not only need in the production process in a large amount of heat energy consumptions, and, because pyroreaction, coking easily takes place in anthracene, influences the purity of reaction yield and product.In addition, carbolineum price height is the reason that directly causes production cost high.
The anthracene slag is the residue behind the crude anthracene purification anthracene, only is applied to fire the sooty raw material at present or does the fuel use.
Summary of the invention
The object of the invention is to invent a kind of method of new production polycyclic aromatic hydrocarbon sulfonate polymer concrete water reducing agent, utilizes the anthracene slag, turns waste into wealth low cost.
The present invention is a raw material with the anthracene slag and the vitriol oil, makes through sulfonation, hydrolysis, condensation, neutralization; Wherein, sulfonation temperature is 70～120 ℃.
Owing to contain nearly 50% phenanthrene in the anthracene slag, also contain polycyclic aromatic hydrocarbonss such as 10～20% anthracenes, 5～10 carbazoles, itself and the vitriol oil are carried out the low-temperature sulfonation reaction, the pyrogenic phenomenon of anthracene can not appear, can improve the purpose product that sulfonation generates, improve product yield.Low-temp reaction condition, technology are easy to control, and handled easily, but save energy are saved production cost.Main is, the present invention adopts the low-cost raw material anthracene slag that in the past can only act as a fuel as production source material, has improved the utility value of resource, and the Financial cost of its production is able to remarkable reduction.
During sulfonation reaction of the present invention, the weight ratio that the anthracene slag and the vitriol oil feed intake is 1: 1.4～1.8.
Suitable feed ratio is the prerequisite that economizes in raw materials, makes full use of raw material.
Embodiment
One, get the raw materials ready:
Prepare anthracene slag 1000kg, 98% vitriol oil, 1400～1800kg, water 400～500kg, formaldehyde 200～350kg, liquid caustic soda respectively.
Two, processing step:
1, sulfonation
The anthracene slag is dropped into the sulfonation reaction still, add 98% vitriol oil, after reacting 2～3 hours under 70～120 ℃ of temperature, naturally cool to 100 ± 10 ℃.
2, hydrolysis
In aforesaid reaction vessel, add cold water, stir.
3, condensation
Add formaldehyde in reactor, condensation reaction is after 3～5 hours, behind the thin up, and each reactor in being pressed into.
4, neutralization
Add neutralization reactant in the neutralization reaction still with liquid caustic soda, adjust pH value to 7～10.Make the polycyclic aromatic hydrocarbon sulfonate yuban, i.e. cement water reducing agent.
5, drying
Also material in the reactor can be carried out drying, obtain the cement water reducing agent of solid, powdery thing.
6, the every index of product:
Dry product outward appearance: chocolate brown powder pH value: 7～10
Surface tension: 67～68mN/m dry product Na
2SO
4Content: 27%
Dry product CL-content :≤0.3% flowing degree of net paste of cement: 215～225mm
Dry product 0.6% volume concrete water-reducing ratio: 16%
Dry product 0.6% volume concrete strength and blank concrete strength ratio:
Concrete coagulates phase R3 R7 R28
Ultimate compression strength MPa 30.5 35.6 43.8
With blank strength ratio 160 155 125.
Claims (2)
