Abstract

The invention discloses an antifoaming agent which comprises, by weight, the following raw materials: 1 part to 3 parts of potassium iodide, 2 parts to 5 parts of boric acid, 1 part to 4 parts of sodium bromide, 2 parts to 4 parts of calcium stearate, 4 parts to 8 parts of nonyl phenol polyoxyethylene ether, 2 parts to 6 parts of tetrabutyl phosphorus bromide, 1 part to 5 parts of benzyl triphenyl phosphorus bromide, 3 parts to 6 parts of isoamylene alcohol, 4 parts to 7 parts of tert-amyl chloride, 1 part to 2 parts of trifluoroacetylacetone and 3 parts to 9 parts of simethicone. The antifoaming agent is rapid in antifoaming and good in inhibition performance, and does not affect basic property of a foaming system. Meanwhile, the antifoaming agent is good in diffusivity and permeability, stable in chemical property, free from corrosion, toxicity and adverse side effect and high in safety.

Description

technical field [0001] The invention belongs to the field of chemistry and chemical engineering, and in particular relates to a defoamer. Background technique [0002] Foam is a thermodynamically unstable system, which cannot be stable. The thermodynamic instability of foam is due to the fact that the total surface area of ​​the liquid in the system is greatly reduced after the foam is broken, so the energy (free energy) of the system is greatly reduced. Defoaming agent, many harmful foams will be produced in the process of industrial production, and it is necessary to add a defoaming agent. There are many types of existing defoamers, some will affect the basic properties of the foaming system, some have poor defoaming effect, poor suppression performance, some are not good enough in diffusivity, and some are not chemically stable. , Safety performance is not high. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a s...
