Organosilicon-modified epoxy resin for robot insulation clothing and preparation method thereof

Abstract

The invention discloses a silicone-modified epoxy resin used for robot insulation clothing and a preparation method thereof, wherein the silicone-modified epoxy resin comprises: alicyclic epoxy resin 60-180 parts by weight 1-30 parts of silicone modifier, 1-5 parts of compatibilizer, 60-180 parts of curing agent, 50-200 parts of reinforcing material, 5-20 parts of flame retardant, 10-15 parts of reactive diluent , 0.5-6 parts of accelerator, 0-2 parts of ultraviolet absorber, 0-2 parts of antioxidant, 0-2 parts of pigment; among them, the silicone modifier is epoxy-terminated silicone oil, and the compatibilizer is polyether One or both of modified silicone oil and octamethylcyclotetrasiloxane. In the present invention, cycloaliphatic epoxy resin is used as the main body of the resin to be modified, epoxy-terminated silicon is used as the modifier, the compatibilizer is added to pre-mix the two to form a uniform phase, and then the curing agent and accelerator are added The realization of chemical blending effectively improves the compatibility of epoxy resin and silicone, and the mechanical properties and other properties of the modified epoxy resin material are significantly improved.

Description

technical field [0001] The invention relates to an organosilicon-modified epoxy resin and a preparation method thereof, in particular to an organosilicon-modified epoxy resin used for a robot insulating clothing and a preparation method thereof, belonging to the technical field of external electrical insulation protection. Background technique [0002] Live work is an important form of power grid construction and maintenance in the future. Live work robot is a machine that can cut and wire transmission lines without power failure. This requires the robot insulating clothing to have good insulation performance to ensure the insulation between its working circuit and the live wire, and also requires the insulating clothing material to have good hydrophobicity to prevent flashover accidents in wet and dirty conditions. At the same time, the insulating clothing is required to have good mechanical strength and flexibility, which can protect the safety of internal circuits and dur...

Problems solved by technology

However, the compatibility between silicone and epoxy resin is not good, and physical mixing is easy to separate phases

[0005] In the prior art, silicone modifiers containing free hydroxyl groups or amino groups are usually used to increase the compatibility of the two. For example, in the Chinese invention patent application with the publication number CN 104177780 A, the silicone modifiers used are containing and The organosilicon compound of the active group of secondary hydroxyl reaction in the epoxy resin; Another example is the Chinese invention patent application whose publication number is CN110655756A, the organosilicon modifying agent that it adopts is the organosilicon containing amino group or hydroxyl group; the above-mentioned modifying agent Although it can increase the compatibility of the two to a certain extent, it is prone to react with the epoxy resin during the mixing process, resulting in local agglomeration and uneven mixing, which will eventually affect the mechanical properties and other properties of the modified epoxy resin.
