Description

A kind of method that sulfonation by-product organic acid prepares mortar auxiliary agent
Technical field
The present invention relates to a kind of preparation methods of building materials auxiliary agent, prepare mortar particular by sulfonation by-product organic acid is neutralized The method of auxiliary agent.
Technical background
Sulfonation by-product organic acid be anionic surfactant production industrial cleaning agent during generate it is all kinds of unqualified Organic acid is generated when organic spent acid and vent gas treatment, is referred specifically in gas phase SO3In sulfonation production, generates when product driving and parking and do not conform to Lattice organic acid and to sulfonated tail gas carry out using high-pressure electrostatic demister system purified treatment generate organic acid.Wherein main component It is organic sulfonic acid ester (sulfuric ester), unreacted raw material and sulfuric acid.
The yield of sulfonation by-product organic acid is according to sulfonation equipment, the difference of technology controlling and process, generally the 0.1 of production ~0.5%.The organic acid production there are contents it is low, impurity content is high, color is deep the deficiencies of, it is difficult to be used as the work of detergent for household use Property raw material.It is inexpensively handled or is done waste material through environmental protection treatment by current each factory, this has resulted in the waste of resource.
CN 102311893A, 102311888A and 104451714A individually disclose a kind of high-pressure electrostatic demister system receipts The reuse method of the organic acid of collection, use organic acid and alkali in reaction kettle in and after, cooling decoloration after be spray-dried, Complex process, it is difficult to which amplification production, the economic benefit is not high.
Summary of the invention
It is the method that raw material prepares mortar auxiliary agent the object of the present invention is to provide a kind of sulfonation by-product organic acid;Utilize the party The mortar that the mortar auxiliary agent of method production is configured has good fluidity and more excellent consistency loss late and compression strength.
The present invention provides following technical schemes:
A kind of method that sulfonation by-product organic acid prepares mortar auxiliary agent for raw material, includes the following steps:
1) water is added in reaction kettle to stir evenly with neutralizer;
2) sulfonation by-product organic acid is added in reaction kettle again, stirring to neutralization reaction is completed;
The mass ratio that feeds intake of the water, neutralizer and sulfonation by-product organic acid is 0.3~0.5:0.2~0.4:1
The neutralizer is the mixture of the liquid alkaline that mass ratio is 0.2~0.4:1 and calcium oxide;
The sulfonation by-product organic acid is the mixture of the AES organic acid that mass ratio is 0.2~0.4:1 and AOS organic acid.
The temperature of the neutralization reaction is controlled at 50 DEG C hereinafter, 50~100 revs/min of mixing speed.
The AES organic acid is the sulfonation by-product organic acid generated during producing AES;The AOS organic acid is production The sulfonation by-product organic acid generated during AOS.
Compared with prior art, the present invention has the following advantages:
(1) using in sulfonation by-product organic acid and production mortar auxiliary agent, can efficiently use in by-product organic acid effectively at Point, turn waste into wealth;
(2) the mortar auxiliary agent for individually AES organic acid being selected to neutralize, although can obtain higher thick when applied to mortar Index is spent, but consistency conservation rate is very poor, 2 hours consistency loss late > 20%.AOS organic acid is individually selected, consistency and consistency are kept Performance is undesirable.The present invention compounds the mortar auxiliary agent for neutralizing production using AES organic acid with AOS organic acid, is applied to mortar When middle, it can make mortar that there is more excellent consistency and consistency retention property, 2 hours consistency loss late < 5%.
(3) using a certain proportion of calcium oxide and liquid alkaline as neutralizer, the mortar auxiliary agent of production has good foaming Performance is obviously improved the compressive property after mortar solidification simultaneously, its 7 days compression strength can achieve after the mortar solidification of configuration 25MPa, compression strength can achieve 35MPa within 28 days.This is because containing part of sulfuric acid in organic acid, through in calcium oxide and liquid alkaline The calcium sulfate, the sodium sulphate that obtain with after originally can serve as the early strength agent of cement mortar.But need exist for control calcium oxide and liquid The ratio of alkali, if compression strength out of proportion (especially 28 days compression strength) can decline instead.
