Embodiment Construction

[0015] Acrylic acid and isooctyl alcohol are used to generate isooctyl acrylate and water under the conditions of concentrated sulfuric acid and a polymerization inhibitor, and then the water is separated through a dehydration tower. The separated aqueous solution is isooctyl wastewater, which contains acrylic acid 0.05%, isooctyl acrylate 0.01%, isooctyl alcohol 0.01%, the technique of described isooctyl wastewater production paper tube glue, this technique is specifically as follows:

[0016] 1) First put water and isooctyl ester wastewater into the enamel kettle, start the agitator, then add polyvinyl alcohol and kaolin in sequence, stir for 30 minutes, and then turn on steam to raise the temperature;

[0017] 2) Dissolve potassium persulfate completely in tap water in advance, continue to heat up to 75 degrees Celsius in the reaction kettle, add two-thirds of the pre-dissolved potassium persulfate, then continue to heat up to 83 degrees Celsius, add the remaining ammonium p...

Abstract

The invention relates to the field of paper pipe glue and particularly relates to a process for producing paper pipe glue from isooctyl ester wastewater. In the process, raw materials include: polyvinyl alcohol, kaolin, corn starch, formaldehyde, hydrochloric acid, sodium hydroxide, a plasticizer, potassium persulfate, ethylene glycol, tap water, and the isooctyl ester wastewater. The formula is reasonable and the process is complete. By using the isooctyl ester wastewater as a raw material for producing the paper pipe glue, a problem of treatment of the isooctyl ester wastewater is solved, and a problem of raw materials of the paper pipe glue is solved, thus saving cost.

Description

technical field [0001] The invention relates to the field of paper tube glue, in particular to a process for producing paper tube glue from isooctyl ester wastewater. Background technique [0002] At present, the production of paper tube glue requires a large amount of raw materials, and the cost is high. At the same time, a large amount of wastewater is generated in the production process of isooctyl ester, and the waste water recycling also requires a lot of funds. We are currently studying a process to use isooctyl ester wastewater to produce paper tube glue. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a process for producing paper tube glue from isooctyl ester wastewater. The formula is reasonable and the process is perfect. [0004] Technical scheme of the present invention: [0005] The process of producing paper tube glue from isooctyl ester waste water, the raw materials of this process are polyvinyl alco...
