Embodiment 1

[0028] Combine 45g palm oil and 5g specific surface area to 80m 2 / g of precipitation hydrophobic silica was added to the reaction flask, stirred, slowly heated to 120°C, kept for 1h, and then cooled to 40°C to obtain silica ointment. In addition, add 20g EBS, 60g aluminum hexadecanoate and 800g palm oil into the beaker, turn on the stirring and slowly raise the temperature to 150°C, keep it for 3h, lower the temperature to 30°C, quickly stir at 800r / min for 1h, add the white prepared in the previous step After the carbon black ointment is uniformly stirred, add 20g CD-50 (Guangdong Petrochemical Research Institute), 30g isotridecyl polyoxyethylene (5) ether and 15g secondary alcohol polyoxyethylene ether (15-S-7) and mix Evenly, defoamer I is obtained.

Embodiment 2

[0030] Make 55g palm oil and 6g specific surface area 120m 2 / g of precipitation hydrophobic silica was added to the reaction flask, stirred, slowly heated to 120°C, kept for 1h, and then cooled to 40°C to obtain silica ointment. Add 70g bis(octadecanoic acid) aluminum and 820g castor oil into the beaker, turn on the stirring and slowly raise the temperature to 130°C, keep it for 2h, lower the temperature to 30°C, quickly stir at 800r / min for 0.5h, add the white prepared in the previous step After the carbon black ointment is evenly stirred, add 30g of butanol polyoxyethylene (10) ether, 15g of EO / PO front copolymer (L61) and 45g of polyoxyethylene sorbitan monooleate (Tween-80) and mix Evenly, defoamer II is obtained.

Embodiment 3

[0032] Add 20g EBS, 60g bis(octadecanoic acid) aluminum and 820g castor oil into the beaker, turn on the stirring and slowly raise the temperature to 150℃, keep it for 2h, lower the temperature to 30℃, quickly stir at 800r / min for 0.5h, add 30g BYK-024 (Germany BYK), 20g butanol polyoxyethylene (10) ether, 25g isomeric tridecanol polyoxyethylene (5) ether and 20g polyoxyethylene sorbitan monooleate (Tween-80) Mix evenly to obtain defoamer III.

Abstract

A plant oil-based defoamer and a preparation method of same. The invention relates to the technical field of defoamers. The defoamer is composed of plant oil, a defoaming substance, a defoaming aid and an emulsifier. The defoaming substance is mainly composed of one or more of fatty acid amide, fatty acid metal soap and white carbon black. Plant oil serves as a dispersion system. One or more of the fatty acid amide, the fatty acid metal soap and the white carbon black serve as the defoaming substance. A low-foam emulsifier is employed for improving stability, water dispersibility and anti-foaming performance of the plant oil-based defoamer. With the plant oil as the dispersion system, the defoamer has better system compatibility, dispersibility, system stability, anti-foaming performance and is green, environment-friendly and degradable. The defoamer has excellent anti-foaming performance in aqueous coatings, aqueous printing ink, aqueous gloss oil, latex, sewage treatment and papermaking black liquid processing.

Description

Technical field: [0001] The invention relates to the technical field of defoamers, in particular to a vegetable oil-based defoamer and a preparation method thereof. Background technique: [0002] Vegetable oil is a compound formed by the combination of unsaturated fatty acids and glycerin. It is widely distributed in nature. It is the oil obtained from the fruits, seeds, and germs of plants. Such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc. The main components of vegetable oil are esters of straight-chain higher fatty acids and glycerol. In addition to palmitic acid, stearic acid and oleic acid, fatty acids also contain a variety of unsaturated acids, such as erucic acid, tungoleic acid, and ricinoleic acid. The existing mineral oil-based defoamer is a defoamer using mineral oil as a dispersed system, which has low system compatibility, dispersibility, system stability, anti-foaming properties, and cannot be regenerated or degraded.
