Description
Technical field
The present invention relates to fine chemistry industry auxiliary agent field, and in particular to a kind of graphene modified organic silicon liquid antifoam agent.
Background technology
Defoamer is broadly divided into mineral oils, organic silicon and polyethers, and this 3 class defoamer exists to a certain extent
Following defect：(1) antifoam performance of polyethers defoamer and suppression foam generation performance are poor compared with organic silicon defoamer,
But its small toxicity, and can high temperature resistant, acid and alkali-resistance；(2) antifoam performance of organic silicon defoamer and suds foam produce better performances,
But its non-refractory, not acid and alkali-resistance；(3) properties of mineral substance oil defoamer defoam between polyethers defoamer and organosilicon
Between agent, but its price is higher.
Therefore, a kind of moderate defoamer is developed, it had both been played organic silicon defoamer and defoams fast, surface
The characteristics of power is low, stable；Also polyethers defoamer acid and alkali-resistance, resistant to elevated temperatures feature can be played, is that the sector is urgently to be resolved hurrily at present
Key technical problem.
The content of the invention
It is an object of the invention to provide a kind of graphene modified organic silicon liquid antifoam agent, the defoamer can not only have
The performance such as graphene oxide high temperature resistant, acid and alkali-resistance, hydrophilic, it can also strengthen the antifoam performance of defoamer and suppress foam generation property
Can, while the preparation method of this defoamer is provided.
To achieve the above object, the invention provides a kind of graphene modified organic silicon liquid antifoam agent, by following weight
The component composition of part：Silicone active thing 50-70 parts, emulsifying agent 20-30 parts, graphene 2-5 parts, thickener 1-1.5 parts, coupling
Agent 1-1.5 parts.
Preferably, described silicone active thing includes methyl-silicone oil, methyl phenyl silicone oil, ethyl silicon oil, polyether-modified
One or more compoundings in silicone oil, dimethyl siloxane hydrolysate.
Preferably, described emulsion adjuvant is nonionic surfactant, and nonionic surfactant gathers including alkyl phenol
One or more compoundings in oxygen vinethene, APEO, AEO.
Preferably, described graphene size is 25-35 μm.
Preferably, described thickener be hydroxymethyl cellulose, hydroxyethyl cellulose, one kind in hydroxypropyl cellulose or
A variety of compoundings.
Preferably, one or more of compoundings in coupling agent A-151, A-171, A-172, A-174, A-187.
The present invention using graphene come modification organic silicon oil, the oxygen-containing functional group of graphenic surface and organic silicone oil is anti-
Should, the unique micron-stage sheet-like structure of graphene so that adsorb organosilicon in graphenic surface as one throws the net and is layered on foams
In system, thus obtained defoamer can play organic silicon defoamer defoaming it is fast, stably, low surface tension the features such as, also possess
The advantages that graphene high temperature resistant, acid and alkali-resistance, hydrophily, and it is moderate, printing and dyeing, ink, coating, papermaking etc. can be widely used in
Industry.
