Abstract
The present invention relates to chemicals technical fields, especially a kind of circuit board defoaming agent, including 50 ~ 120 parts of polyethers, 10 ~ 18 parts of organosilicon, 2 ~ 5 parts of dispersing agent, 2 ~ 4 parts of surfactant, 3 ~ 6 parts of tackifier, 2 ~ 5 parts of antioxidant, 5 ~ 10 parts of stearic acid, the defoaming agent can carry out defoaming and foam inhibition dedicated for circuit board, be a kind of environmentally friendly, at low cost, function admirable material.
Description
Technical field
The present invention relates to chemicals technical field, especially a kind of circuit board defoaming agent.
Background technique
Defoaming agent, also referred to as defomaing agent are that surface tension is reduced in food processing process, and foam is inhibited to generate or eliminate
Generate the food additives of foam.China, which is permitted workable defoaming agent, the fatty acid ester compounded object of silicone emulsion, higher alcohols, polyoxy
Ethylene polyoxypropylene pentaerythrite ether, polyoxyethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether and polyoxyethylene polyoxypropylene
7 kinds of glycerin ether, dimethyl silicone polymer etc..Defoaming agent is mostly liquid compound product, is broadly divided into three classes: mineral oils, organic
Silicon class, polyethers.Mineral oil defoaming agent is usually made of carrier, activating agent etc..Organic silicon defoaming agent generally comprises poly- two
Methylsiloxane etc..Organic silicon defoaming agent dissolubility is poor, at normal temperature have antifoaming speed quickly, foam inhibition it is preferable, but
High temperature issues layer estranged, antifoaming speed compared with the features such as slow, foam inhibition is poor.
The problems such as generally existing defoaming of defoaming agent currently on the market is slow, and defoaming effect is undesirable.
Summary of the invention
In order to overcome the shortcomings of that existing defoaming agent single variety, functionality are weak, the present invention provides a kind of circuit board use
Defoaming agent.
The technical solution adopted by the present invention to solve the technical problems is: a kind of circuit board defoaming agent, including polyethers 50 ~
120 parts, 10 ~ 18 parts of organosilicon, 2 ~ 5 parts of dispersing agent, 2 ~ 4 parts of surfactant, 3 ~ 6 parts of tackifier, 2 ~ 5 parts of antioxidant, tristearin
5 ~ 10 parts of acid, the defoaming agent can carry out defoaming and foam inhibition dedicated for circuit board, be a kind of environmentally friendly, at low cost, function admirable
Material.
The invention has the advantages that the defoaming agent can be carried out dedicated for circuit board defoaming and foam inhibition, be it is a kind of environmental protection,
At low cost, function admirable material.
Specific embodiment
Below by specific embodiment, invention is further explained.
Embodiment 1
A kind of circuit board defoaming agent, counts based on parts by weight, 66 parts of polyethers, 12 parts of organosilicon, 3 parts of dispersing agent, surface-active
2 parts of agent, 4 parts of tackifier, 3 parts of antioxidant, 5 parts of stearic acid.
Embodiment 2
A kind of circuit board defoaming agent, counts based on parts by weight, 75 parts of polyethers, 14 parts of organosilicon, 4 parts of dispersing agent, surface-active
2 parts of agent, 4 parts of tackifier, 4 parts of antioxidant, 7 parts of stearic acid.
Embodiment 3
A kind of circuit board defoaming agent, counts based on parts by weight, 85 parts of polyethers, 15 parts of organosilicon, 4 parts of dispersing agent, surface-active
3 parts of agent, 5 parts of tackifier, 4 parts of antioxidant, 7 parts of stearic acid.
One embodiment of the present invention has been described in detail above, but the content is only that the present invention is preferably implemented
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should still be within the scope of the patent of the present invention.
