Low-smoke halogen-free flame retardant polyolefin material

Abstract

The invention discloses a low-smoke halogen-free flame retardant polyolefin material, which is prepared from the following raw materials in percentage by weight: 40 to 50 percent of basic resin, 0.1 to 1 percent of a vulcanizing agent, 0.1 to 3 percent of tackifying resin, 0.1 to 3 percent of an activator, 0.1 to 3 percent of a hydrocarbon resin mixture and 40 to 60 percent of a flame retardant system. The low-smoke halogen-free flame retardant polyolefin material has the characteristics of high flame retardancy, low smoke content, no halogen and high mechanical property.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a low-smoke, halogen-free flame-retardant polyolefin material. Background technique [0002] Fire is one of the most serious disasters faced by human beings. With the improvement of electrification, the proportion of fires caused by wires and cables in fires is increasing day by day, and according to statistics, the loss exceeds 5 billion yuan. In order to reduce the loss caused by fire, researchers modified the wire and cable with flame retardant. In the past, it was mainly modified by halogen-containing flame retardants. And flame retardant products also have certain potential safety hazards and environmental protection problems in the process of use. Chinese patent CN1445973A discloses a low-smoke halogen-free flame-retardant polyolefin cable compound and a preparation method thereof. The raw materials are ethylene-vinyl acetate polymer 65-75, high-dens...
