Problems solved by technology

[0003] The current fireproof cables generally fall into two categories, one is the copper conductor copper sheathed mineral insulation type represented by magnesium oxide insulation, this type of cable cannot be produced in large lengths, and the installation and maintenance are highly specialized. The other is flexible fireproof cables, such as cables with ceramicized silicone rubber as insulation and sheath, but ceramicized silicone

Abstract

The invention belongs to the field of wire and cable production and manufacturing and discloses a PVC insulating material for manufacturing of fireproof cables and a preparation method of the PVC insulating material. The material quickly forms a compact and hard protective shell with a self-supporting effect after fire occurrence and plays a great role in heat insulation and flame retardation. Thepreparation method can be implemented by adoption of existing conventional equipment, raw materials are easy to acquire, and reasonable cost and high cost performance are realized. The PVC insulatingmaterial is prepared from, by mass, 80-100 parts of PVC resin powder, 20-40 parts of epoxy resin, 30-80 parts of a plasticizer, 10-200 parts of filler, 5-20 parts of auxiliary agents, 0-5 parts of acoloring agent, 5-20 parts of a lubricant, 3-10 parts of a stabilizing agent, 20-200 parts of combustion shell-forming additives, 20-30 parts of aluminum oxide, 15-80 parts of a cosolvent, 5-8 parts of a flame retardant and 5-10 parts of a smoke suppression agent.

Description

technical field [0001] The invention belongs to the field of electric wire and cable manufacturing, and in particular relates to a PVC insulating material for manufacturing fireproof cables and a preparation method thereof. Background technique [0002] With the continuous progress of social development, the growth rate of various buildings in our country is very fast, especially the number of high-rise buildings is increasing rapidly. These buildings are extremely unfavorable for rescue and escape after a fire occurs, and the requirements for fire safety are very high. High, the selected materials are preferably non-combustible or flame-retardant materials, and fire-resistant cables are also used when selecting cables, because when a fire occurs, various equipment cannot be cut off when evacuating personnel and firefighting, including emergency lighting and Induction signs, including broadcasting of evacuation personnel, including the control and delayed closing of fire shu...
