Problems solved by technology

However, in order to improve the flame retardant level of the resin, more flame retardants are usually added to the resin composition to meet the requirements for the flame retardant level. However, as the amount of flame retardant added increases, the mechanical properties of the resin composition will decrease. Affected, but the amount added is too small to meet the requirements of the flame retardant grade

Abstract

The invention discloses a halogen-free flame retardant and a resin alloy containing the halogen-free flame retardant, wherein the halogen-free flame retardant is composed of the following components in parts by weight: 1-10 parts by weight of carbon nano-tube nano-particles, 10-20 parts by weight of carboxylated carbon nano-tube nano-particles, 5-10 parts by weight of metal oxide mixture, 20-40 parts by weight of expandable graphite nano-particles and 15-30 parts by weight of phosphorus-containing halogen-free compounds. According to the halogen-free flame retardant disclosed by the invention,the flame retardancy grade of the resin is improved, and the mechanical property of the resin alloy is not reduced or not greatly reduced.

Description

technical field [0001] The invention relates to the field of resin alloys, in particular to a halogen-free flame retardant and a resin alloy containing the halogen-free flame retardant. Background technique [0002] When a fire occurs, halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas during the flame-retardant process, causing secondary hazards. The new flame retardant system has a small amount of smoke when burning, and does not produce toxic and corrosive gases. Halogen-free flame retardant additives are mainly phosphorus compounds and metal hydroxides. These two types of compounds do not volatilize or produce corrosive gases when burned, and are called pollution-free flame retardants. In addition, there are several new types of halogen-free flame retardants such as silicon-based flame retardants and nitrogen-based flame retardants. These new halogen-free flame retardants have become new products th...
