Embodiment 1
[0022] This embodiment provides a self-curing insulation protection material, which can provide guarantee for long-term stable and safe power supply, and is widely used in insulation and waterproofing of 10 / 20KV high-voltage overhead bare wires, high-voltage overhead wire fittings leads, and insulation of cross-arms Protection, insulation protection of switch cabinets and substation busbars, and insulation protection of power connectors, knife switches, and isolating switches. At the same time, it can also provide protection for the waterproof sealing of various feeder connectors in communication base stations.
[0023] The material can be extruded as needed, sealed and stored in a vacuum packaging bag. When in use, it can be completely attached to the parts that need insulation protection, without heating, and the air will automatically cure.
[0024] Among them, the self-curing insulating and protective material includes raw material components and parts: polysiloxane 1: 5-25...
Embodiment 2
[0038] This embodiment provides a manufacturing process for manufacturing the self-curing insulating and protective material in Example 1. When manufacturing the above self-curing insulating and protective material, the following manufacturing process is used:
[0039] Step A: First batching and kneading once, the raw material components and quantities used in the batching are as follows: polysiloxane 1: 5-25 parts, polysiloxane 2: 2-15 parts, polysiloxane 3 : 60-93 parts, Filler 1: 60-90 parts, Filler 2: 3-12 parts, Filler 3: 25-45 parts, Filler 4: 10-20 parts, Filler 5: 1-6 parts, Auxiliary 1: 0.3-10 parts, auxiliary agent 2: 0.1-8 parts, cross-linking agent: 4-16 parts, catalyst: 0.08-2 parts, each part is determined according to the actual finished product output, and the unit of each part can be kilogram.
[0040] Among them, polysiloxane 1 uses one or more polysiloxanes with a viscosity (25°C) of 1500-100000CS; A polysiloxane; Polysiloxane 3 selects one or more polysilo...

Abstract
The invention discloses an automatic-curing insulation protective material and a manufacturing technique thereof. The automatic-curing insulation protective material is prepared from 5-25 parts of polysiloxane 1, 2-15 parts of polysiloxane 2, 60-93 parts of polysiloxane 3, 60-90 parts of filler 1, 3-12 parts of filler 2, 25-48 parts of filler 3, 10-20 parts of filler 4, 1-6 parts of filler 5, 0.3-10 parts of assistant 1, 0.1-8 parts of assistant 2, 4-16 parts of crosslinking agent and 0.08-2 parts of catalyst. The automatic-curing insulation protective material is prepared by kneading the three polysiloxanes with different viscosities, five different fillers, two assistants, crosslinking agent and catalyst three times. The product cured by room temperature air has the advantages of high voltage resistance, favorable flame retardancy, certain thermal conductivity, excellent flexibility, excellent plasticity and excellent bonding property. The product is very convenient to mount and demount.
Description
technical field [0001] The invention relates to the field of chemical materials, in particular to an automatic curing insulating protection material and a manufacturing process thereof. Background technique [0002] In the prior art, in the electric power industry: Ethylene-propylene rubber tapes are often used for insulation and sealing of overhead bare wires, fittings, leads, cross arms, etc., stretching, wrapping, and winding at parts that require protection and sealing; switch cabinets and substation mothers The heat-shrinkable material is used for the insulation protection of the row, etc., and it needs to be heated with fire to make the heat-shrinkable material tightly sealed with the busbar; in the communication industry: the insulation and waterproof seal of various types of feeder connectors in communication base stations are mostly cold-shrinkable sleeves. Pull out the support bar from the feeder joint and shrink it tightly. The use of these methods for insulation...
