Embodiment Construction

[0015] A kind of organic silicon defoamer with bactericidal effect, it is made by the raw material of following parts by weight: dimethyl silicone oil 40, silicon dioxide 20, stearamide 0.3, potassium iodide 0.3, sodium carbonate 0.3, tributyl phosphate Ester 0.4, clinoptilolite powder 4, sodium tripolyphosphate 0.3, mannitol 0.3, salt 2, barium stearate 0.3, glycerin 1, copper sulfate 0.4, activated carbon 0.5, water 10.

[0016] Described a kind of organic silicon defoamer with bactericidal effect, preparation method comprises the following steps:

[0017] (1) Clinoptilolite powder was soaked in 3% hydrochloric acid solution for 4 hours, drained and extruded into flakes, then activated with a tumble dryer at 230°C for 20 minutes, and crushed into 150 meshes to obtain activated powder for use;

[0018] (2) After mixing the activated powder with silicon dioxide and stearamide, add appropriate amount of water, disperse evenly at 300rpm, then dry the slurry, ball mill at 200rpm ...

Abstract

The invention discloses an organosilicon defoamer with a bactericidal action. The organosilicon defoamer is prepared from the following raw materials in parts by weight: 40-60 parts of simethicone, 20-30 parts of silicon dioxide, 0.3-0.5 part of stearamide, 0.3-0.5 part of potassium iodide, 0.3-0.5 part of sodium carbonate, 0.4-0.6 part of tributyl phosphate, 4-6 parts of clinoptilolite powder, 0.3-0.4 part of sodium tripolyphosphate, 0.3-0.5 part of mannitol, 2-3 parts of common salt, 0.3-0.6 part of barium stearate, 1-3 parts of glycerine, 0.4-0.6 part of copper sulfate, 0.5-0.7 part of activated carbon and 10-20 parts of water.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to an organic silicon defoamer with bactericidal effect. Background technique [0002] In the process of industrial production, if there is a large amount of foam, it will bring a lot of troubles to the production process, such as the production capacity will be greatly limited; cause waste of raw materials and products; affect product quality; pollute the environment, etc. Therefore, how to effectively control the foam in the production process has become the focus of researchers. Nowadays, defoamers are generally used to eliminate foam generated in industrial production. [0003] Defoamers commonly used in industry can generally be divided into three categories: organic defoamers, silicone defoamers and polyether defoamers. Silicone defoamer is composed of dimethyl silicone oil and SiO2 in a certain proportion. The defoamer made in this way has the characteristics of...
