Excellent preparation method of emulsified oil for hydraulic supports!
October 29, 2021
If the hydraulic support emulsified oil of good quality is applied on the hydraulic support, it can have a good anti-rust effect and can effectively reduce the abrasion of the hydraulic support. However, if the inferior quality emulsified oil is selected, it will not only do this. Excellent results, and even have a counterproductive effect. It should be known that the preparation principle of emulsified oil for hydraulic supports with high quality is very delicate, and only after these processes can high-quality emulsified oil for hydraulic supports be obtained.
Hydraulic support emulsified oil refers to a mixture of emulsifiers prepared from two or more emulsifier monomers in proportion. According to the principle of emulsifier preparation; the emulsifier prepared by using two or more emulsifiers is more stable than the emulsifier prepared by using one emulsifier alone. Therefore, the use of the compound emulsifier prepared by the proprietary technology can conveniently and quickly prepare various emulsified products with stable properties without the trouble of choosing and formulating emulsifiers by oneself. The seed emulsion semi-continuous method was used to synthesize a polysiloxane/acrylate core-shell structure composite emulsion with high silicone content, and the effect of the type, compound ratio and mass concentration of the emulsifier on the performance of the silicone/acrylate shell-core emulsion was studied. The influence of latex particle size, distribution and structure. The results show that the particle size of the latex particles synthesized by the anionic emulsifier sodium dodecyl sulfate (SDS), sodium dodecyl sulfonate (SDS-2) and sodium dodecylbenzene sulfonate (SDBS) increase in order When SDS is used in combination with non-ionic emulsifier OP-10, as the mass fraction of OP-10 increases, the polymerization rate and conversion rate decrease, the chemical stability increases, the particle size of the latex particles increases, and the distribution becomes wider. Excellent ratio of emulsified oil for hydraulic supports. With the increase of the compound emulsifier concentration, the polymerization rate increases, the conversion rate increases, and the particle size of the latex particles decreases and the distribution widens. By changing the emulsifier addition method, the particle size distribution of the latex particles can be reduced. To produce particles, it is necessary to strictly control the concentration of emulsifier, so that the added shell monomers are in a "starvation" state, enrich on the surface of latex particles, initiate polymerization, and form a surface "transition layer" to form hydraulic support emulsified oil.
