Abstract

The invention provides a high-insulativity polyamide resin inflaming retarding and insulating material, and relates to the technical field of new materials. The flame retarding and insulating materialis prepared through the following raw materials: polyamide resin, phenolic resin, aluminum hydroxide, expanded graphite, magnesium hydrate, silicon dioxide, alumina, vermiculite, octadecyl benzyl dimethylammonium bromide, glass fibers, cotton fibers, Na-montmorillonite, urea, propylene carbonate, montmorillonoid, barium sulfate, a plasticizer, an antioxidant, a silane coupling agent, an accelerant and a compatilizer. According to the high-insulativity polyamide resin inflaming retarding and insulating material, the silane coupling agent is gamma-aminoethyl aminopropyl trimethoxysilane, so that the reinforcing effect of the glass fibers and the cotton fibers to the product can be effectively improved, and moreover, the volume resistivity of the product can be greatly improved while the mechanical performance, the heat resisting performance and the impact intensity of a composite material are improved; and the insulating effect is obvious.

Description

[0001] This application is a divisional application of an invention patent application titled: A highly insulating polyamide resin flame-retardant insulating material, application date: April 26, 2018, and application number: 2018103866019. technical field [0002] The invention relates to the technical field of new materials, in particular to a highly insulating polyamide resin flame-retardant insulating material. Background technique [0003] With the rapid development of the national economy, people's electricity consumption has risen sharply, and the requirements for power quality are getting higher and higher. Most cables are insulating materials, and other specific properties must also be specified. In important places such as petrochemical, electric power, metallurgy, high-rise buildings and densely populated places, the flame retardant and fireproof performance of cables are particularly important. The loss of human body and property is relatively large; and the fla...
