Problems solved by technology

However, while silicone fluids with low relative molecular weight endow the composition with the desired properties, their volatile and low viscosity characteristics make it difficult to remain in the formulation, easy to separate, and may even flow uncontrolled during use. Transdermal, limiting its use in cosmetic compositions
If the viscosity of the solution is increased and the evaporation loss of the volatile low molecular weight silicone oil is slowed down by using a common thickener, it may reduce the spreadability of the silicone oil and leave a severe slippery feeling on the skin
And existing siloxane fluid has the problem of poor waterproof performance

Description

technical field [0001] The invention belongs to the technical field of silicone elastomers, and in particular relates to a silicone elastomer gel and its preparation method and application. Background technique [0002] Organosilicon compounds refer to a class of compounds with repeated Si-O-Si groups as the main chain and other organic groups connected to silicon atoms. Silicone elastomers, simply speaking, are silicon-containing network polymers that exist in various forms and have different degrees of crosslinking. According to different properties, they are mainly divided into: white smooth powder silicone resin microspheres, organic Silicone resin emulsion and silicone elastomer gel in the form of colorless gel. Silicone elastomers are widely used in electronics, medical, leather, shipping, and daily chemical industries due to their excellent thermal stability, electrical insulation, ozone resistance, and physiological inertness. [0003] Silicone gel can be regarded ...
