Abstract
The invention discloses a low-smoke halogen-free polyolefin cable material and preparation method thereof, wherein the low-smoke halogen-free polyolefin cable material is prepared by the following step: mixing the composite raw materials ethylene-vinyl acetate copolymer EVA, high density polyethylene HDPE, PE fire retardant, zinc borate, roasted zeolite powder, nano calcium carbonate powder, silane coupling agent, attapulgite, acid esters, anti-oxidant, lubricating agent and coupling agent based on parts by weight proportioning. The preparation method of the invention is simple and convenient to operate. The formula of composite raw materials is rational. The prepared cable material has high mechanical properties and high fire resistance, and can resist high temperature. When the material is burned, it is low in smoke and is non-toxic.
Description
Technical field
The present invention relates to a kind of low-smoke halogen-free polyolefin cable material and preparation method thereof, belong to field of cables.
