The novel defoaming agent can fast complete defoaming to satisfy use requirements during use.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a novel defoamer for papermaking. Background technique [0002] Defoamers need to be used in the papermaking process, but the current defoamers cannot meet the needs of use. Contents of the invention [0003] In order to overcome the shortcomings of existing defoamers, the invention provides a novel defoamer for papermaking. [0004] The technical solution adopted by the present invention to solve its technical problems is: a novel paper-making defoamer, comprising: 2-6 parts of fatty alcohol, 1-4 parts of polydimethylsiloxane, 3-3 parts of potassium iodide 8 parts, 5-8 parts of boric acid, 2-5 parts of calcium stearate. [0005] According to another embodiment of the present invention, it further includes that the optimal number of fatty alcohols is 4 parts. [0006] According to another embodiment of the present invention, it further includes that the optimal number of p...
