A kind of technological method of utilizing ethoxylated bisphenol a diacrylate waste water to prepare thickener

Abstract

The invention discloses a process method for preparing a thickener by using ethoxylated bisphenol A diacrylate waste water. The waste water synthesized from ethoxylated bisphenol A diacrylate is used as a raw material, and waste water, styrene, p- The mixture of diallyl phthalate and acrylamide is subjected to free radical polymerization to prepare a thickener. The process flow is perfect, the preparation method is simple, the raw materials are cheap, and it is easy to operate. It realizes the deep resource utilization of waste water and near zero discharge. , creating a new industrial output, and compared with the existing thickeners on the market, the prepared thickener has reliable performance, and even some parameters are slightly better than similar products, so that the thickener extracted from wastewater also has Very good market competitiveness.

Description

Technical field [0001] The present invention relates to waste water treatment chemicals, and in particular relates to a process utilizing ethoxylated bisphenol A diacrylate esters prepared thickeners wastewater. Background technique [0002] High shear force will reduce the consistency of paste in the printing process, it is necessary to increase the system viscosity thickener employed, so that the system has good rheological properties, so that the dye and fiber can be better together. Thickener properties determine the nature of the printing paste, and directly affect the vividness of color, pattern clarity, texture and other properties of printed products. Therefore, when printing, screening stable, secure, applicable and cost-effective thickener is essential. [0003] In the preparation of materials such as bisphenol A ethoxylated bisphenol A diacrylate process using acrylic acid and ethoxylated, will produce effluents containing acrylic acid and its esters, the portion of th...

Problems solved by technology

The treatment methods commonly used at home and abroad all adopt the incineration method. Since the waste water cannot be directly burned, heavy oil needs to be added to support the combustion, and the treatment cost per ton is high. If the treatment is not timely, the waste liquid will automatically explode and generate a large amount of solid waste. It will release dioxins into the atmosphere and cause secondary pollution; although the catalytic oxidation method can effectively decompose pollutants, the key lies in the catalyst, which has strong specificity and has high restrictions on water inflow conditions. Only a few acrylic acid manufacturers adopt this method. In addition, the catalytic wet oxidation method requires high temperature and high pressure conditions to treat wastewater, and there are also potential safety hazards.

However, its anaerobic method, aerobic method, ion exchange fiber method, etc. are still in the theoretical research stage, and there are still many technical problems that have not been effectively overcome and cannot be promoted.
