Abstract

The invention relates to the technical field of defoaming agents, in particular to a high-efficiency defoaming agent. The high-efficiency defoaming agent is prepared from the components in parts by weight: 3 to 6 parts of low-hydro silicone oil, 1 to 4 parts of n-amyl alcohol, 2 to 5 parts of white carbon black, 5 to 8 parts of malonic acid, and 1 to 5 parts of amino silicon oil. The high-efficiency defoaming agent can be used for quickly accomplishing defoaming work and meets the use demand when in use.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a high-efficiency defoamer. Background technique [0002] The defoamer can eliminate the foam in the production environment when it is used, but the current defoamer has a long acting time during use, cannot quickly complete the defoaming work, and is inconvenient to use. Contents of the invention [0003] In order to overcome the deficiencies of the existing defoamers, the invention provides a high-efficiency defoamer. [0004] The technical solution adopted by the present invention to solve the technical problem is: a high-efficiency defoamer, comprising: 3-6 parts of low hydrogen-containing silicone oil, 1-4 parts of n-amyl alcohol, and 2-5 parts of white carbon black in parts by weight , 5-8 parts of malonic acid, 1-5 parts of amino silicone oil. [0005] According to another embodiment of the present invention, it further includes that the optimal number of low-hydroge...
