Problems solved by technology

Due to the large amount of flame retardant, it is difficult to compound plastics, and the mechanical properties of the obtained products are poor
Due to the large amount of flame retardant used, the stability of the resulting plastic product is poor, the flame retardant is precipitated, and the surface is easy to absorb water
Conventional halogenated flame retardants and phosphorus flame retardants are prone to produce more smoke and other toxic gases when they are flame retardant

Abstract

The invention provides a halogen-free flame-retardant resin and a preparation method thereof. The halogen-free flame-retardant resin comprises the following components in percentage by weight: 50-80%of a thermoplastic substrate resin, 15-35% of glass flakes, 5-10% of a thickening agent, 5-10% of a compatilizer, 0.5-5% of an epoxy resin, 0.2-1% of a coupling agent, 0.2-1% of an antioxidant and 0.2-1% of a lubricant. According to the technical scheme of the invention, the glass flakes in plastic form a labyrinth structure, a plastic material is filled with the glass flakes, very good flame retardancy is achieved, very good barrier properties and mechanical properties can be achieved, the halogen-free flame-retardant resin is applied to barrier packaging materials or containers, and high requirements of automobile plastic fuel tank materials on strength, flame retardancy and gas barrier properties are met.

Description

technical field [0001] The invention belongs to the field of halogen-free flame-retardant polymers, and in particular relates to a halogen-free flame-retardant resin and a preparation method thereof. Background technique [0002] During the development of nearly a hundred years, plastics and plastic products have brought great contributions and infinite convenience to human production and life. However, since most plastics are flammable products, the production of plastic parts with flame-retardant requirements is subject to limit. In order to meet the requirements of flame retardancy, the current domestic market mainly uses flame retardants compounded with halogen-containing organic compounds and antimony trioxide to produce flame-retardant plastics. In recent years, brominated flame retardants have been plagued by the problem of dioxins. At the same time, the polymer materials used for flame retardancy (bromine-antimony system) will generate a large amount of smoke and co...
