Problems solved by technology

After installing the composite wall bushing, the hole between the bushing and the wall needs to be sealed with bricks and cement mortar, which is time-consuming and laborious, and it is easy to damage the wall bushing
If conventional busbars and busbars are used to transmit power through the wall, a certain gap safety distance between the busbars, busbars and the wall will be maintained, and small animals will climb in the gaps, resulting in potential safety hazards of short circuits
The sealant or sealant currently on the market has certain fluidity and is directly used to seal the gap between the wall conductor and the wall. Before the sealant or sealant is cured, it will flow and the effect is not good. good, not pretty

Abstract

The invention relates to high-voltage-insulation sealing adhesive. The high-voltage-insulation sealing adhesive comprises a first composition and a second composition which are stored separately, wherein the first composition comprises the following components in parts by weight: 40-60 parts of hydroxy-terminated polysiloxane, 3-10 parts of silicon dioxide, 10-60 parts of a filler, 1-5 parts of a cross-linking agent and 0.2-1 part of a silane coupling agent; the second composition comprises the following components in parts by weight: 30-60 parts of hydroxy-terminated polysiloxane, 0-10 parts of polymethyl siloxane, 10-60 parts of a filler and 0.8-1.5 parts of a catalyst. The first composition and the second composition are stored separately, and during room-temperature mixing, sulfuration reaction is performed on the hydroxy-terminated polysiloxane, the cross-linking agent and the silane coupling agent under the action of the catalyst; after the sulfuration reaction, a product is excellent in flame retardance, electrical performance and bonding strength, and has shockproof and waterproof functions; the two compositions are shaped as blocks, and can be directly kneaded into any shapes by hands for sealing, so that the high-voltage-insulation sealing adhesive is easy and convenient to use.

Description

technical field [0001] The invention relates to a sealing glue, in particular to a high-voltage insulation sealing glue. Background technique [0002] In the transmission and transformation substation of the power system, many indoor devices are connected to the outdoors and need to pass through the wall. Since the live conductor cannot directly contact with ordinary cement bricks, when the conductor passes through the wall, the most commonly used method is to use it on the wall. Expensive composite wall bushings replace conventional busbars, busbars and other conductors for power transmission. After the composite wall-piercing sleeve is installed, the hole between the sleeve and the wall needs to be sealed with bricks and cement mortar, which is time-consuming and laborious, and it is easy to damage the wall-piercing sleeve. If conventional busbars and busbars are used to transmit power through the wall, a certain gap safety distance between the busbars, busbars and the wa...
