Problems solved by technology

[0004] However, polyolefin resins are extremely flammable, so it is urgent to modify them with flame retardancy. The existing halogen flame retardants will cause serious environmental pollution. A new environmentally friendly flame retardant olefin resin composition The manufacturing method is subject to further research and development

Abstract

The invention provides a preparation method of olefin resin composition. The preparation method comprises steps as follows: (1), an oxide of iron and an oxide of Mo are supported on a carrier, and a flame retardant is prepared; (2), 100 parts of polyolefin resin, 4-8 parts of the flame retardant prepared in the step (1) and 0.1-2 parts of a silicone coupling agent are mixed at a high speed of 1,800-2,000 r/m at the temperature ranging from 80 DEG C to 100 DEG C for 10-15 minutes; (3), the materials are mixed, melted, extruded and pelletized. The preparation method has the benefits that the olefin resin composition has good flame retardancy and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of polyolefin products, in particular to a method for manufacturing an olefin resin composition. Background technique [0002] Polyolefin is a polymer compound formed by polyaddition reaction of olefin. Such organic polymers are usually composed of many identical or different simple olefin molecules (such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene Such as α-olefins and certain cycloolefins) are formed by polymerization. Common polyolefins include polyethylene and poly-1-butene. Polyolefins are mainly produced by high-pressure polymerization, low-pressure polymerization (including solution method, slurry method, bulk method, gas phase method) and other methods. [0003] Polyolefin resin has the characteristics of low relative density, good chemical resistance and water resistance; good mechanical strength and electrical insulation. It can be used in films, pipes, p...
