Problems solved by technology

The patent utilizes the high rigidity of the polyphenylene ether material itself. By adding soft elastomers and adjusting the components of the material, the above problems can be partially overcome, such as reducing the hardness of the blend system and obtaining a good feel. However, the blend low mechanical strength
Among the four examples provided by this patent application, the test results show that the tensile strength is up to 9.5MPa, and the mechanical properties are not high.

Abstract

The invention relates to a halogen-free flame retardant polyphenylene oxide polyphenyl ether (PPE) cable material composition and a preparation method thereof. The composition comprises the following components in percentage by mass: 20 to 50 percent of polyphenylene oxide polyphenyl ether (PPE), 24 to 30 percent of elastomer, 5 to 20 percent of polyolefin, 20 to 35 percent of flame retardant agent, 0 to 5 percent of compatilizer and 0.1 to 1.0 percent of antioxidant. The halogen-free flame retardant PPE cable material composition prepared by the method has the advantages of high flexibility, high mechanical property, high flame retardance, high resilience and the like, does not comprise halogen, is an environmental-friendly product, and can be widely applied to insulation sheaths of halogen-free ultrathin lead connecting leads, direct current electric wires and plugs, electrical product electric wires, telecommunication facility cables, cable sheaths and the like.

Description

technical field [0001] The invention relates to a PPE cable material composition, in particular to a halogen-free flame-retardant PPE cable material composition. The invention also relates to a preparation method of the PPE cable material composition, which belongs to the field of high polymer processing and modification. Background technique [0002] Because the traditional polyolefin cable materials use polyvinyl chloride and halogen-containing flame retardants as the basic flame retardant system, they will release a large amount of harmful substances to the environment and human body under the influence of heat and light during processing, natural aging of the environment and waste combustion. The harmful effects of smoke and gases such as toxic and corrosive hydrogen halides are attracting increasing attention. Halogen-free flame retardant technology, as a newly developed flame retardant material development method, is applied in the preparation of cable materials, so th...
