Preparation method of flame-retardant smoke-suppressing socket material

Abstract

The invention discloses a preparation method of a flame-retardant smoke-suppressing socket material, belonging to the technical field of novel materials. The preparation method comprises the followingsteps: carrying out a grafting reaction on polyethylene wax to obtain grafted polyethylene wax; reacting the grafted polyethylene wax with a diphenyl chlorophosphate-tetrahydrofuran solution under the condition of a catalyst to obtain a polyethylene wax compound; mixing the polyethylene wax compound with polycarbonate and an inorganic filler, adding the formed mixture into a double-screw extruder, and carrying out melt extrusion granulation. The socket material prepared by using the method provided by the invention has excellent flame retardance and smoke suppression performance, so the socket material can be better applied to the field of sockets, and is greatly improved in safe electricity utilization property.

Description

technical field

[0001] The invention belongs to the technical field of new materials, in particular to a preparation method of a flame-retardant and smoke-suppressing socket material. Background technique

[0002] Socket, also known as power socket, switch socket. A socket is a socket into which one or more circuit wirings can be inserted, through which various wirings can be inserted. This facilitates connection to other circuits. Through the connection and disconnection between the line and the copper piece, the final connection and disconnection of this part of the circuit is achieved.

[0003] Most electrical products are composed of high molecular polymer materials, which have a high fire hazard. "China Fire Statistical Yearbook" shows that in 2006, fires caused by electrical reasons accounted for 26.1% of the total number of fires of various types, ranking first in various statistics, and electrical fires caused by switches and sockets accounted for a larger proport...
