Embodiment 1

[0030] A kind of preparation method of good defoamer of stability, comprises the steps:

[0031] (1) Preparation of defoaming functional additives:

[0032] a. First put the crop straw into the pulverizer for pulverization, and then take out the pulverized straw for later use;

[0033] b. Put the crushed straw obtained in operation a into a steam explosion tank for steam explosion treatment, and take it out for later use after completion;

[0034] c. Put the attapulgite into the calcination furnace for calcination, and take it out after 1 hour for later use;

[0035] d. Put starch and water into the reactor according to the weight ratio of 1:6, heat to keep the temperature in the reactor at 78°C, stir continuously for 42 minutes, then add 1% of the total mass to the reactor dropwise After the phosphoric acid solution was continuously stirred for 1.2 hours, it was taken out and poured into ethanol for precipitation, then rinsed with deionized water, then vacuum filtered and d...

Abstract

The invention discloses a preparation method of a defoaming agent with good stability. The preparation method comprises the following steps: (1), preparing a defoaming functional auxiliary agent; (2),weighing raw materials for use; (3), preparing a finished product. The preparation method of the defoaming agent is improved; the preparation method is reasonable in coordination of the steps and convenient to popularize and apply; the prepared defoaming agent is rapid in defoaming, strong in foam-inhibiting ability, stable in using quality, good in comprehensive characteristics and very high inmarket competitiveness and production benefits.

Description

technical field [0001] The invention belongs to the technical field of defoamer processing, and in particular relates to a preparation method of a defoamer with good stability. Background technique [0002] Defoamer, also known as defoamer or foam breaker, will produce many foams that affect production in the process of industrial production, and it is necessary to add a defoamer. It is widely used to remove harmful foam produced in the production process of latex, textile sizing, food fermentation, biomedicine, paint, petrochemical, papermaking, industrial cleaning, sewage treatment and other industries. However, most of the defoamers produced and sold in the existing market have problems such as unstable quality and poor defoaming treatment effect, which urgently need to be improved. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of the defoamer with good stability aiming at the existing problems. [00...
