Abstract

The invention relates to the technical field of refractory materials, and particularly relates to a preparation method of a flame-retardant refractory material. The preparation method comprises the following steps: (1) placing polyvinyl chloride, magnesium aluminum alloy and a rare earth compound into a high-speed mixer for high-speed mixing, when the temperature reaches 96-120 DEG C, adding a dispersing agent, a flame retardant and a smoke suppressant and flame retardant synergist, and continuously carrying out high-speed stirring to obtain powder; (2) when the temperature of the powder reaches 90-150 DEG C, discharging the powder to a storage hopper, cooling the powder to 45-60 DEG C, and pouring the powder into a double-screw granulator for granulation; and (3) carrying out air-heat cold cutting on the granulated powder to obtain the flame-retardant refractory material. The preparation method provided by the invention is stable in forming, high in efficient and high in yield, and isconvenient for large-scale full-automatic production, the raw material source is wide, the cost is low, the resource utilization rate is high, the use of chemical reagents is reduced, the method is more green and environmentally friendly, and the flame-retardant and smoke-suppressant effects of the prepared flame-retardant refractory material are good, and the flame-retardant refractory materialhas a wide application prospect in the field of cables.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a method for preparing a flame-retardant refractory material for cables. Background technique [0002] The base material of wire and cable is mainly PVC plastic, PVC plastic is one of the five general-purpose synthetic plastics, and it is the second largest plastic variety in the world after polyethylene. Due to its good physical and mechanical properties, polyvinyl chloride resin can be used in the production of building materials, packaging materials, electronic materials, daily consumer goods, etc., and is widely used in various fields such as industry, agriculture, construction, transportation, power telecommunications, and packaging. Wire and cable are indispensable and important facilities for industrial and agricultural production and modern life, and occupy a very important position in my country's national economy. [0003] In recent years, with the rapid d...
