Abstract

The invention discloses a non-organic silicon defoamer. A preparation method for the non-organic silicon defoamer comprises the following steps: (1) preparation of raw materials and instruments, wherein the raw materials comprise a carrier, a main defoamer, a diluent, a defoaming synergist, an emulsifier and distilled water, and the production instruments comprise a reactor, a temperature controldevice, a temperature indication controller and a precise reinforcing electric stirrer; and (2) mixing the carrier and the main defoaming substance: putting the carrier and the main defoaming substance into the reactor, connecting a power supply, and starting the precise reinforcing electric stirrer to fully mix the carrier and the main defoaming substance. The non-organic silicon defoamer disclosed in the invention is prepared by compounding and mixing 10% of polyether L61, 8% of mixed higher fatty alcohol, paraffin, the emulsifier and the defoaming synergist, has a large diffusion coefficient and high emulsifying, dispersing and permeating capacity, is wide in application range, can be used within a pH range of 4-10, and can withstand strong acid and strong alkali environments.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to a non-organic silicon defoamer. Background technique [0002] In the papermaking, paint, textile, food, pharmaceutical and petrochemical industries, a large amount of foam will be generated due to various reasons, which will make the production impossible or affect the product quality. In order to avoid the impact of foam on the production process, people usually use adding Defoamer method to eliminate foam. [0003] Silicone defoamers commonly used in the market today will increase the cost while improving the defoaming dispersibility, and in industries such as papermaking, coating, and starch processing, silicone defoamers cannot play a role efficiently, and Common non-silicon defoamers are not as good at suppressing foam as silicone defoamers, and have low defoaming efficiency for dense foams. We propose a non-silicon defoamer that is convenient to solve the abo...
