摘要:

将具有阻燃剂和辐照敏化剂双重功能的含烯丙基环三磷腈(CP-Allyl),通过熔融共混的方式引入到由低密度聚乙烯和乙烯-醋酸乙烯共聚物组成的基体中,制备了一系列基于有机-无机阻燃复配剂的新型无卤阻燃聚乙烯基复合绝缘材料。进一步通过100~190 kGy剂量下的电子束辐照,实现了复合材料的辐照交联,并建立了辐照剂量与交联度以及材料性能的关系。研究结果表明,含有功能性环三磷腈衍生物的辐照交联复合材料具有优良的力学强度、阻燃性和电绝缘性能。力学强度在14.5 MPa以上,极限氧指数为28.2%~32.4%,电阻达到2.47×1012 Ω以上,因而有希望在电线电缆领域获得应用。

Abstract:

An allyl functionalized cyclotriphosphazene, which is expected to serve as flame retardant and irradiation sensitizer, is introduced into the matrix composed of low-density polyethylene and ethylene vinyl acetate copolymer by melt blending. Based on the organic-inorganic complex flame retardants, a family of new halogen-free flame retardant insulating composites is prepared. Furthermore, the irradiation crosslinking of the composites is conducted by electron-beam irradiation at the irradiation doses of 100~190 kGy, and the relationship between irradiation dose and properties is investigated. The results indicate that the irradiation crosslinked composites containing functional cyclotriphosphazene have excellent mechanical strength, flame retardancy and electrical insulation properties, and they may be promising for wire and cable applications.
