Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a novel water-soluble high molecular polymer thickener quick-dissolving liquid reforming agent and its processing method, which solves the problem that the current water-soluble high molecular polymer thickener suspension has a short stable time; Narrow range of choices (only limited to hydrocarbon solvents); less applicable thickeners (only applicable to guar gum, hydroxypropyl guar gum, carboxymethyl hydroxypropyl guar gum, hydroxyethyl cellulose and carboxymethyl hydroxyethyl One or more of base cellulose); artificially synthesized water-soluble polymer thickeners, such as polyacrylamide quasi-inverted microlatex, have low molecular weight (below 10 million), low solid content of the emulsion, and low production costs. High, short settling time issues

Embodiment 1

[0015] In the reaction ax, add 210 parts of water, 50 parts of sorbitan monooleate, 630 parts of diesel oil, and 20 parts of emulsifiers respectively, start stirring, and the stirring speed is 80 rpm. While blowing nitrogen gas, the temperature inside the reactor was raised to 55°C within 30 minutes. Grind the high carbon alcohol ester of acrylate (C 32 ~C 36 ) 110 parts were added slowly, and then 3 parts of potassium persulfate initiator was added, and the temperature in the reaction ax was continued to rise to 85°C within 30 minutes, and maintained for about 3 hours. When the temperature rises sharply, take measures to control the temperature below 120°C and above 85°C, keep it for about 2.5 hours, and cool down naturally. A light brown semi-gummy oil was obtained. Get 10 grams of this product, add in the beaker that fills 40 grams of diesel oil, stir evenly with glass rod, add 50 grams of guar gum powder, stir well, obtain uniform, stable slightly soluble suspension, se...

Embodiment 2

[0017] In the reaction ax, add 90 parts of water, 100 parts of sorbitan monooleate, 690 parts of salad oil, and 60 parts of emulsifier respectively, start stirring, and the stirring speed is 110 rpm. While blowing nitrogen gas, the temperature inside the reaction ax was raised to 50°C within 30 minutes. Grind the high carbon alcohol ester of acrylate (C 30 ~C 35 ) 60 parts were added slowly, and then 8 parts of potassium persulfate initiator was added, and the temperature in the reaction ax continued to rise to 120°C within 30 minutes, and maintained for about 2.5 hours. When the temperature rises sharply, take measures to control the temperature below 120°C and above 90°C, keep it for about 3 hours, and cool down naturally. A pale yellow semi-gummy oil was obtained. Get 8 grams of this product, add in the beaker that is filled with 45 grams of salad oil, stir evenly with a glass rod, add 47 grams of guar gum powder, stir well, obtain uniform, stable slightly soluble suspen...

Embodiment 3

[0019] In the reaction ax, add 180 parts of water, 70 parts of sorbitan monooleate, 580 parts of salad oil, and 4 parts of emulsifier respectively, start stirring, and the stirring speed is 130 rpm. While blowing nitrogen gas, the temperature inside the reaction ax was raised to 60° C. within 30 minutes. Grind the high carbon alcohol ester of acrylate (C 36 ~C 40 ) 150 parts were slowly added, and then 10 parts of potassium persulfate initiator was added, and within 30 minutes, the temperature in the reaction ax was continued to rise to 80°C, and maintained for about 4 hours. When the temperature rises sharply, take measures to control the temperature below 120°C and above 80°C, keep it for about 4 hours, and cool down naturally. A pale yellow semi-gummy oil was obtained. Take 11 grams of this product, add it to a beaker containing 44 grams of kerosene, stir it with a glass rod, add 45 grams of polyacrylamide powder, and stir it to get a uniform and stable slightly soluble ...

Abstract

The present invention relates to a kind of surfactant and its processing method. It has material comprising acrylic high carbon alcohol ester 60-150 weight portions, sorbitol ester 50-100 weight portions, deionized water 90-210 weight powder, organic solvent 580-690 weight portions, emulsifier 20-60 weight portions and polymerization initiator 3-10 weight portions. Modifying the water soluble polymer thickener with the instant liquid modifier has the advantages of wide selective solvent range, wide liquid modification range, easy operation, being suitable for large scale production, etc.

Description

technical field [0001] The invention relates to a surfactant and a processing method thereof. Background technique [0002] With the rapid development of the world economy, the water-soluble polymer thickener known as industrial monosodium glutamate is used more and more widely, and the dosage is increasing. In the process of using water-soluble polymer thickener products, there are The problem is becoming more and more prominent, mainly in two aspects, on the one hand, it is aimed at natural water-soluble polymer thickeners, such as guar gum, konjac gum, carob gum, seaweed gum, etc., with guar gum For example, because guar gum powder particles rapidly increase in viscosity when exposed to water, if they are not fully dispersed before contacting water, it is very easy to form a rubber packet (a rubber powder clump with a dry core inside and a dissolved core outside). Swelling sol, the sol blocks the water outside, making the dry core in the bag extremely difficult to dissol...
