preparation example Construction

[0036] In yet another typical embodiment of the present application, a method for preparing a fire-resistant mineral silicone rubber material is provided. The preparation method uses any of the above-mentioned fire-resistant mineral silicone rubber compositions as a raw material, and includes the following steps: S1 , using quaternary ammonium salts to modify montmorillonite to obtain modified montmorillonite; S2, mixing methyl vinyl silicone rubber, modified montmorillonite, low-melting glass powder, aluminum hydroxide and polyols Plasticizing to obtain the fire-resistant mineral base material; and S3, granulating the fire-resistant mineral base material to obtain the fire-resistant mineral silicone rubber material.

[0037] Firstly, montmorillonite is modified with quaternary ammonium salt to obtain modified montmorillonite, so as to improve the mixing and dispersion effect of montmorillonite in methyl vinyl silicone rubber; then plasticize and granulate each raw material, T...

Abstract

The invention provides a fireproof mineral silicone rubber composition, a fireproof mineral silicone rubber material, a preparation method thereof and a power line containing the fireproof mineral silicone rubber material. The fireproof mineral silicone rubber composition comprises, by weight, 50-100 parts of methyl vinyl silicone rubber, 30-50 parts of montmorillonite, 5-10 parts of quaternary ammonium salt surface modifier, 10-20 parts of low-melting-point glass powder, 30-50 parts of aluminum hydroxide and 5-10 parts of polyol. A ceramic layer structure formed by the fireproof mineral silicone rubber composition is stable and even in mechanical performance distribution, and the toughness and fireproof performance of the power line is further increased when the ceramic layer structure is used as the sheath of the power line.

Description

technical field [0001] The invention relates to the field of fireproof materials, in particular to a fireproof mineral silicone rubber composition, a fireproof mineral silicone rubber material, a preparation method thereof and a power cord comprising the same. Background technique [0002] The surface sheath of the air conditioner power cord is made of flame-retardant PVC material, and the structure of the inner core is made of flame-retardant polyolefin material extruded and coated copper wire. On the one hand, when the socket catches fire, the continuous flame will spread along the power cord to the air conditioner, causing the air conditioner to catch fire. Sparking can also cause serious fire hazards. [0003] At present, wires and cables in industry and large buildings mostly use fireproof mineral insulated cables. The mineral layer of the cable will be sintered into a ceramic solid at high temperature to form a good heat insulation layer and prevent the copper wires b...
