Embodiment 1

[0023] Put simethicone oil and silicon dioxide with a viscosity of 1000cs into the reaction kettle at a mass ratio of 100:2, stir slowly, raise the temperature to 160°C, and continue stirring for 3 hours to obtain a composite silicone oil.

[0024] Add 10 parts of the above compound silicone oil, 10 parts of epoxy soybean oil, 6 parts of polyether, 5 parts of fatty alcohol polyoxyethylene ether, 1 part of sorbitan stearate (Span 60), polyoxyethylene sorbitan Put 1 part of fatty acid ester (Tween 80), 2 parts of glycerin and 0.2 part of glycerol monostearate in a reaction kettle, raise the temperature to 60° C., and stir for 0.5 h. Add the remaining amount of water, and then stir rapidly for 45min. Finally, use an emulsification pump to emulsify to obtain defoamer 1#.

Embodiment 2

[0026] Put simethicone oil with a viscosity of 300cs, simethicone oil with a viscosity of 3000cs, and silicon dioxide in a mass ratio of 60:40:2.5 into the reaction kettle, stir slowly, raise the temperature to 180°C, and continue stirring for 3.5h to obtain a composite silicone oil.

[0027] Add 8 parts of the above compound silicone oil, 12 parts of epoxy soybean oil, 3 parts of polyether, 6 parts of fatty alcohol polyoxyethylene ether, 2 parts of sorbitan stearate (Span 60), polyoxyethylene sorbitan Put 2 parts of fatty acid ester (Tween 80), 2 parts of glycerin and 0.1 part of glycerol monostearate in a reaction kettle, raise the temperature to 50°C, and stir for 1 hour. Add the remaining amount of water, and then stir rapidly for 1h. Finally, emulsify with an emulsification pump to obtain defoamer 2#.

Embodiment 3

[0029] Put simethicone oil with a viscosity of 300cs, simethicone oil with a viscosity of 3000cs and silicon dioxide into the reaction kettle at a mass ratio of 60:40:5, stir slowly, heat up to 180°C, and continue stirring for 4 hours to obtain a composite silicone oil.

[0030] Add 6 parts of the above compound silicone oil, 14 parts of epoxy soybean oil, 3 parts of polyether, 6 parts of fatty alcohol polyoxyethylene ether, 2 parts of sorbitan stearate (Span 60), polyoxyethylene sorbitan Put 2 parts of fatty acid ester (Tween 80), 2 parts of glycerin and 0.1 part of glycerol monostearate in a reaction kettle, raise the temperature to 70°C, and stir for 1 hour. Add the remaining amount of water, and then stir rapidly for 1.5h. Finally, emulsify with an emulsification pump to obtain defoamer 3#.

Abstract

The invention discloses a defoamer containing silicone oil and epoxidized soybean oil. The defoamer has excellent defoaming, foam inhibition and anti-shearing performances. The defoamer containing silicone oil and epoxidized soybean oil, taking 100 parts as a baseline, comprises the following components in parts by mass: 5 to 15 parts of compound silicone oil, 5 to 15 parts of epoxidized soybean oil, 2 to 10 parts of polyether, 1 to 6 parts of fatty alcohol-polyoxyethylene ether, 1 to 6 parts of sorbitan tristearate, 1 to 8 parts of polyoxyethylene sorbitan fatty acid ester, 2 to 5 parts of glycerinum, 0.1 to 2 parts of glycerin monostearate and the balance of deionized water.

Description

technical field [0001] The invention relates to a defoamer and a preparation method thereof, in particular to a defoamer containing silicon oil and epoxy soybean oil and a preparation method thereof. Background technique [0002] Defoamer, also known as defoamer, defoamer or foam breaker, is mainly used to eliminate foam generated during production, and is widely used in chemical, food, paper, pharmaceutical, coating, industrial cleaning, wastewater treatment, textile and other industries It is an important class of fine chemicals. The active components of defoamers widely used in industry mainly include silicone oil and its derivatives, polyethers, mineral oils, alcohols, esters and amides. Epoxidized soybean oil is a chemical product obtained by oxidizing soybean oil. It has excellent thermal stability and light stability, and is non-toxic. It is the most widely used non-toxic plasticizer and plasticizer for polyvinyl chloride. Stabilizer, but epoxidized soybean oil is l...
