Definitions
- the present invention relates to a silicone oil compound for use as an antifoaming agent in which the particle size of the organopolysiloxane-silica crosslinked product in the oil compound is within a certain range, and has initial defoaming properties and, in particular, defoaming even in an alkaline foaming liquid.
- the present invention relates to a silicone oil compound for antifoaming agents, which is excellent in durability and internal addition stability, and an antifoaming agent composition containing the same.
- Silicone antifoaming agents have very low surface tension and are insoluble in many solvents. , paper industry, textile industry, pharmaceutical industry, etc.
- a silicone-based antifoaming agent an oil compound antifoaming agent in which a silicone oil such as dimethylpolysiloxane, methylphenylpolysiloxane, or methylvinylpolysiloxane is mixed with finely divided silica has been widely used.
- an emulsion type antifoaming agent obtained by emulsifying the oil compound type antifoaming agent with a surfactant and dispersing it in water, or a mixture of an organopolysiloxane modified with a polyoxyalkylene group and an oil compound type antifoaming agent.
- Self-emulsifying antifoaming agents and the like are also commonly used.
- their antifoaming performance largely depends on the oil compound type antifoaming agent that is the basic raw material, and the conventional technology lacks initial defoaming performance, defoaming sustainability especially against alkaline foaming liquids, and internal addition stability. I had a problem.
- Patent Document 4 Patent No. 5922305
- Patent Document 5 Japanese Patent No.
- antifoaming compositions basically have high antifoaming performance, and in particular, can obtain alkali resistance such as little deterioration over time even in an alkaline foaming liquid. In many cases, problems such as deterioration in emulsion stability and deterioration in dispersibility rather than deterioration in antifoaming properties have occurred. Conversely, if the crosslinked product is too small, the desired antifoaming properties and antifoaming persistence in an alkaline foaming liquid cannot be obtained, and therefore the desired performance may not be obtained. In conventional antifoaming compositions, there is no evaluation method for confirming the above defoaming performance, and each evaluation must be performed under actual usage conditions or conditions similar to them, and quality control is required. It was also difficult to control the quality variation in terms of the surface.
- the present invention provides an oil compound that exhibits good initial defoaming properties, less deterioration over time, and excellent defoaming performance even in an alkaline foaming liquid, and a defoaming agent composition containing this oil compound. intended to
