Abstract

The invention discloses non-toxic flame-retardant composition for cables and a preparation method of the composition. The non-toxic flame-retardant composition for cables takes modified montmorillonite as a main material matched with a nano activator, antimony trioxide, ammonium polyphosphate and other flame-retardant aids, and the composition has the advantages of high flame retardance, low costand low smoke during burning. When the composition is applied to preparation of rubber, the prepared rubber can have good low-smoke flame retardance and can bring good mechanical performance to the rubber. The preparation method of the flame-retardant agent is simple, raw materials are easy to obtain, and the flame-retardant composition has higher popularization and application values.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a non-toxic flame-retardant composition for cables and a preparation method thereof. Background technique [0002] Generally speaking, a cable is made of one or more mutually insulated conductors and an outer insulating layer, which transmits power or information from one place to another. With the rapid development of the economy, more and more places need cables to transmit power or other information, so there are stricter requirements for the manufacture of cables. The sheath of the cable is an indispensable structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and insulating the cable core from water, air and other media to avoid leakage. Resin is the main material for the preparation of cable sheaths, so the properties of the resin directly determine the properties of the prepared cable sheaths. [0003] The classif...
