Abstract
The present invention relates to a preparation method of industrial defoaming agents, which belongs to the manufacture field of organic chemical industry defoaming agents. The method comprises the following steps: first, under the condition of a catalyst, polymerizing glycerine into polyglycerine with the polymerization degree at 2 to 10, then adding in glycerine fatty acid ester or fatty acid according to the determined mass ratio for ester exchange, and obtaining products of the present invention. The present invention has the advantages of simple and convenient production processes, easy availability of materials, good defoaming and foam-suppressing effect and suitability for processes, such as paper making, sugar manufacturing, ferment, etc.
Description
Technical field
The present invention relates to a kind of preparation method of industrial defoaming agent, prepared defoamer is applicable to froth breaking in papermaking, printing and dyeing, fermentation, the sugar refining technology, presses down bubble.
Background technology
In papermaking, printing and dyeing, fermentation and sugar refining technology process, often have a large amount of foams and produce, influence carrying out smoothly of technical process,, must use the defoamer elimination or reduce foam in order to guarantee to produce.
At present defoamer is of a great variety, mainly contains the grease class, polyethers, polysiloxane-based and sulfonation grease etc.But the application of these defoamers all has certain limitation, and has complex manufacturing, costs an arm and a leg or use shortcomings such as inconvenience, and is particularly not good in industrial results of use such as papermaking, sugarings.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of defoamer, prepared defoamer is applied in papermaking, printing and dyeing, fermentation and the sugar refining technology good froth breaking and suds suppressing properties are arranged, and produces easily, and is easy to use.
Purpose of the present invention is achieved through the following technical solutions:
First step polymerization
With glycerine is raw material, stirs to heat up and the adding catalyst, and 180 °-250 ℃ reactions 1-5 hour, getting the degree of polymerization was the polymerization glycerine of 2-10, and its reaction equation is as follows:
n＝2～10
The second step ester exchange
Get above-mentioned polymerization glycerine 15-65 mass parts, about 120 ℃ of preheatings add fatty acid glyceride or aliphatic acid 35-85 mass parts, and little amount of catalyst, 150 ℃-250 ℃ stirring reaction 2-4 hour.
Reaction equation:
n＝2～10 m＝8～18 x＝1～3
Best catalyst is KOH or NaOH in the two-step reaction, Na
2CO
3, K
2CO
3, MnO
2, can be one or more.
Be product of the present invention through the reacted waxy solid of above-mentioned ester exchange (or esterification).
Product of the present invention has good defoaming effect, as will further improving antifoam performance, product 60-65 mass parts after the also desirable above-mentioned second step ester exchange, add dimethicone 2-5 mass parts, white carbon black 1-3 mass parts, sorbester p17 and Tween 80 2-5 mass parts, water 30-35 mass parts, disperseed 5-15 minute under rotating speed 800～1000rpm with dispersion machine, get yellow-white paste object.This product has good froth breaking, suds suppressing properties.
In order to check the defoaming effect of product, the present invention uses a kind of special apparatus and method, and is specific as follows:
(1) instrument and equipment: one in 500ml graduated cylinder, one of the air pump of flow 1～2L/min (disperser of band gas).
(2) reagent:
The sample configuration: sample disperses dilution with distilled water, and the ratio of sample and water is 1: 30
Expanding foam solution: expanding foam solution uses the process fluid that produces foam in the practical application, when being used to refine sugar process, with the syrup of 50 ° of BX, is heated to 70 ℃.
(3) method of operating
Measure the 100ml expanding foam solution in the 500ml graduated cylinder, the unlatching air pump makes and bubbles to 500ml, adds 1ml rapidly and has diluted good defoamer, calculates the time when foam drops to liquid level thus, is foam time.Again open air pump, the time when foam rises to 300ml again is for pressing down the bubble time.When sugar industry was used, foam time should be less than 30 seconds, and pressing down the bubble time should be greater than 5 minute.
