Abstract

The invention discloses a step-type flame-retardant rubber material. The material comprises in parts by weight: 80-120 parts of rubber, 80-200 parts of a flame retardant, 40-60 parts of filler, and 0.3-2 pats of an auxiliary agent, and the flame retardant is an inorganic flame retardant powder coated with a polymer modifier on the surface. A preparation method comprises the following steps: preparing and modifying the inorganic flame retardant powder, and preparing the flame-retardant rubber material. According to the step-type flame-retardant rubber material and the preparation method thereof, the obtained rubber material has multi-stage flame-retardant characteristics, has the flame-retardant effect in a relatively wide high temperature range, and greatly improves the safe use performance of the rubber.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a stepped flame-retardant rubber material and a preparation method thereof. Background technique [0002] Rubber products can be seen everywhere in people's production and life, and are widely used in various fields such as road traffic, housing construction, medical engineering, aerospace and navigation, etc., and play an important role in promoting urban construction and improving people's lives. However, since the main components of rubber are carbon and hydrogen, they are extremely flammable, especially nitrile rubber and some halogen-containing rubbers, which are very flammable. People's lives and property safety have also formed a huge threat. In the prior art, flame retardant properties of rubber are usually improved by adding flame retardants. Flame retardants, also known as flame retardants, fire retardants or fire retardants, are functional materials that en...
