Abstract
The invention provides a highly-efficient aliphatic water reducer modified by 2-naphthol waste liquor and a preparation method thereof, belonging to the technical field of 2-naphthol waste liquor in wastewater. The highly-efficient aliphatic water reducer modified by the 2-naphthol waste liquor is prepared from the following raw materials by weight proportion: 110 to 120 parts of sodium sulfite, 490 parts of 2-naphthol waste liquor, 100 parts of acetone and 290 parts of formaldehyde. According to the invention, substances like 2- naphthalenesulfonic acid and sodium sulfate in sodiumnaphthalenesulfonate-filtered waste liquor in 2-naphthol production process are used to modify an aliphatic water reducer, so 2-naphthol waste liquor is reused and is prevented from causing pollution and damage on environments and human bodies; meanwhile, the wastewater does not need any treatment like concentration or other physical and chemical treatments and can be directly recycled, so energy consumption is saved.
Description
Technical field
The present invention relates to liquid waste disposal technique field, a kind of waste liquid being specifically related to produce in a kind of bisnaphthol production process does not need the application of any process directly in aliphatic category high performance water-reducer.
Background technology
China produces 2-naphthols and mainly adopts the sulfonation-alkali fusion route of naphthalene, obtains through sulfonation, hydrolysis, neutralization, alkali fusion, acidifying, the process such as refining.This process mainly produces twice waste liquid, once: the mother liquor after sodium naphthalene sulfonate suction strainer; Another time is: crude phenols boil the mother liquor of the aqueous phase after layering after cooling, press filtration.
Beta naphthal factory effluent has complicated component, concentration is high, toxicity is large, color is dark, soda acid resiliency is strong, be difficult to biochemical degradation and to human body and the feature such as environmental hazard is larger.The problem of environmental pollution caused thus is never effectively solved.The process mainly mode such as distillation and concentration, chemical treatment of current appearance 2-naphthols waste liquid, liquid waste disposal is complicated, power consumption is large, processing cost is high.
Mother liquor after sodium naphthalene sulfonate suction strainer, main component has 2-sodium naphthalene sulfonate, sodium sulfate etc., and 2-sodium naphthalene sulfonate has activity, can the reaction such as condensation, graft copolymerization, and the modification participating in aliphatic water reducing agent for it provides feasibility in theory.Sodium sulfate is comparatively stable does not participate in the reaction such as sulfonation, condensation, but it is a kind of hardening accelerator in concrete, and the sodium sulfate in waste liquid exists with water reducer mother liquor always, and the aliphatic water reducing agent of synthesis can be made to have early potent fruit.
Summary of the invention
(1) technical problem solved
For the deficiencies in the prior art, the invention provides a kind of waste liquid modified aliphatic high-efficiency water reducing agent of 2-naphthols and preparation method thereof, utilize the materials such as 2-naphthene sulfonic acid in the waste liquid in 2-naphthols production process after sodium naphthalene sulfonate suction strainer, sodium sulfate, modification is carried out to aliphatic category water reducer, make the recycling of 2-naphthols waste liquid, prevent its pollution that Environmental insults is caused and infringement, any process such as concentrated or other physical chemistry need not be carried out to waste water simultaneously, can utilize by direct circulation, save power consumption.
