Embodiment 1

[0013] Embodiment 1: A thermochromic insulating material, which consists of the following ingredients in parts by weight: 11-20 parts of polybutylmethacrylate, 10-20 parts of linear low-density polyethylene, polymethyltriethoxysilane 3-7 parts, 0.5-3 parts of silane coupling agent, 15-20 parts of trimethylolpropane triacrylate, 4-6 parts of 1,8-diazabicyclo(5,4,0)7-undecene , Antioxidant 1-1.5 parts, thermochromic ink 15-20 parts, flame retardant 5-10 parts.

Embodiment 2

[0014] Embodiment 2: A thermochromic insulating material, which consists of the following components by weight: 15 parts of polybutylmethacrylate, 15 parts of linear low-density polyethylene, 5 parts of polymethyltriethoxysilane, silane 2 parts of coupling agent, 18 parts of trimethylolpropane triacrylate, 5 parts of 1,8-diazabicyclo(5,4,0)7-undecene, 1 part of antioxidant, 15 parts of thermochromic ink 8 parts, 8 parts of flame retardant.

Embodiment 3

[0015] Embodiment 3: a thermochromic insulating material, the silane coupling agent is vinyltrimethoxysilane. All the other parts are identical with embodiment 1 or 2.

[0016] In view of the above-mentioned embodiments, the present invention can have higher insulation performance and flame-retardant performance than traditional insulating materials covered with cables and wires, and improve the service life of cables and wires. Moreover, once the conductor covered by the insulating layer has heat accumulation during use, it will be reflected by the color change of the wire, so that maintenance personnel can easily find and eliminate potential safety hazards during the inspection process, and repair and replace them in time.

Abstract

The invention discloses a temperature-sensing color-changing insulating material and belongs to the field of a cable insulating material. The temperature-sensing color-changing insulating material is used for coating a cable and wire conductor and consists of the following components in parts by weight: 11 to 20 parts of poly-n-butyl methacrylate, 10 to 20 parts of linear low-density polyethylene, 3 to 7 parts of polymethyl triethoxy silane, 0.5 to 3 parts of a silane coupling agent, 15 to 20 parts of trimethylolpropane triacrylate, 4 to 6 parts of 1,8-dinitrogen bicyclo(5,4,0)7-hendecene, 1 to 1.5 parts of an antioxidant, 15 to 20 parts of temperature-sensing color-changing printing ink and 5 to 10 parts of a flame retardant. According to the above technical scheme, the temperature-sensing color-changing insulating material can realize semiconductor heat accumulation in a lead and realize fault response through color change of an insulating layer coating the lead so as to reduce the risk of potential safety hazard in the inspection process of cables and wires.

Description

technical field [0001] The invention belongs to the field of cable insulating materials, and in particular relates to a thermochromic insulating material. Background technique [0002] During the use of cables and wires, due to improper operation or installation during the production process or use, short circuits or heat concentration points will be formed in the conductors of cables or wires, and these potential problems are in cables or wires. It's hard to see under the cladding of the outer layer of insulation. Contents of the invention [0003] The purpose of the present invention is to provide a temperature-sensitive discoloration insulating material, which can realize the fault response through the discoloration of the insulating layer coated on the outside of the wire when the heat of the conductor inside the wire is accumulated, thereby reducing the safety of cables and wires during the inspection process. Hidden risks. [0004] To achieve the above object, the ...
