Problems solved by technology

Adding a flame retardant can improve the flame retardant performance of the base material, but the halogenated flame retardant contains halogen elements, which will release a large amount of waste particles and corrosive gases when burned, so although the addition of the flame retardant can achieve flame retardancy ignitable effect, but there are still potential hazards to the environment

Abstract

The invention discloses a halogen-free flame-retardant material for a plug and a preparation method thereof. The main point of the technical solution is to include the following components in parts by weight: 55-75 parts of polypropylene; 1-35 parts of polyorganosiloxane; glass 10‑50 parts of fiber; 0.1‑1.5 parts of flame retardant synergist. Adding polyorganosiloxane to polypropylene as a flame retardant can prevent the burning of polypropylene and suppress the smoke generated during the burning of polypropylene. The amount of flame retardant is small, and the produced materials have long service life and good weather resistance. Well, the anti-aging effect is good.

Description

technical field [0001] The invention relates to the field of flame retardant materials, in particular to a plug and a halogen-free flame retardant material for the plug. Background technique [0002] With the development of information science and technology, electronic products continue to expand and update, and the requirements for the use of plugs for electronic and electrical equipment are also getting higher and higher. At the same time, the requirements for the plug's environmental protection are also getting higher and higher. [0003] At present, an ordinary power plug is composed of a plug core and a rubber insulating layer wrapped outside the plug core. The rubber insulation layer generally uses polyvinyl chloride or polyethylene as the base material, and a flame retardant is added to the base material. The flame retardant used includes halogenated flame retardants and metal oxides. Adding a flame retardant can improve the flame retardant performance of the base m...
