Abstract

The invention discloses a fire-resistant insulating material with mechanical strength and a preparation method thereof. The fire-resistant insulating material is prepared from the following raw materials in parts by weight: 100-200 parts of mica powder, 20-30 parts of alkali-free glass fibers, 20-30 parts of glass fibers, 50-60 parts of a binder, 30-40 parts of methylbenzene, 20-40 parts of a polyether ammonium curing agent and 10-20 parts of aluminum hydroxide powder. The mica powder is a powdery mixture which is composed of mica, aluminosilicate, carbonate and a high-heat-resistance inorganic mineral having undergone grinding and smashing and uses the ground and smashed mica as a main component. The high-heat-resistance inorganic mineral is one or more selected from a group consisting ofa clay material, a high-aluminum material, a corundum material, a silicon material, a magnesium material and a silicon carbide material. The ire-resistant insulating material of the invention has thetechnical effects of high heat resistance and high mechanical strength.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a fire-resistant insulating material with mechanical strength and a preparation method thereof. Background technique [0002] Insulating materials are non-conductive materials under the allowable voltage, but they are not absolutely non-conductive materials. Under the action of a certain applied electric field strength, processes such as conduction, polarization, loss, breakdown, etc. will also occur, and aging will occur after long-term use . [0003] Insulating materials are the basis and guarantee for the development of electrical products, and play a particularly important role in the development of motors and electrical industries. The development and progress of insulating materials depends on the development of polymer materials and directly restricts and affects the development and progress of electrical products. . [0004] Insulating materials are the key...
