Problems solved by technology

However, compositions using powdered phosphorus- or nitrogen-containing flame retardants such as melamine cyanurate, melamine phosphate, ammonium polyphosphate, phosphinate, or diphosphinate can produce " Coke" precipitates, which will reduce production efficiency and affect product quality
Chinese patent CN101827885A discloses a flame retardant composition, with piperazine and melamine (poly/pyro) phosphate compound, silicone oil, and monoamide compound of higher aliphatic monocarboxylic

Abstract

The invention discloses a halogen-free flame-retardant elastomer composition. The halogen-free flame-retardant elastomer composition comprises the following components in percentage by weight: 15-70% of thermoplastic polyester elastomer, 0-50% of styrene type elastomer and/or polyolefin type elastomer, 25-40% of flame retardant and 2-5% of processing aids, wherein the flame retardant is of a mixture containing piperazine phosphate, melamine phosphate and ammonium polyphosphate. The halogen-free flame-retardant elastomer composition disclosed by the invention can effectively inhibit the precipitation of coke charge during the processing process and improve the processing performances of the composition, has the characteristics of high halogen-free flame-retardant grade, good mechanical properties, good anti-aging performance and easiness in extrusion molding and processing, and is very suitable for power cords, data transmission lines and the like of high-end consumptive electronic and electrical appliances.

Description

technical field [0001] The invention relates to an elastomer composition, in particular to a halogen-free flame-retardant elastomer composition and its application. Background technique [0002] Halogenated compounds such as polyvinyl chloride (PVC) and neoprene have excellent flame retardant properties and are widely used in the wire industry, but they will produce a large amount of toxic gases during fire or incineration, which will cause great damage to the human body and the environment. Hazard, recently, the demand for halogen-free flame-retardant elastomers used to replace PVC wire and cable materials has exploded. [0003] At present, there are many composite materials specially developed for halogen-free flame-retardant wires, such as polyolefin / inorganic flame retardant (due to the need to add a large amount of flame retardant, which affects the mechanical properties of the composite, such as insufficient flexibility and elasticity), poly Olefin or elastomer / intume...
