Abstract

The invention provides a halogen-free nano flame-retardant TPE material and a preparation method thereof and solves the technical problems of characteristic loss and poorer dispersibility of an existing halogen-free nano flame-retardant TPE material elastomer. In every one hundred weight parts, the halogen-free nano flame-retardant TPE material is prepared from the following ingredients in content: 10 to 30 parts of SEBS or SBS, 5 to 40 parts of extending oil, 1 to 5 parts of flame-retardant synergist, 2 to 15 parts of polypropylene and 20 to 50 parts of inorganic nano hydroxide filling masterbatch. The invention further provides a preparation method of the halogen-free nano flame-retardant TPE material.

Description

technical field [0001] The invention relates to a flame-retardant material and a preparation method thereof, in particular to a halogen-free nano flame-retardant TPE material and a preparation method thereof. Background technique [0002] With the continuous development of environmental protection requirements and the environmental requirements for the use of flame retardant materials, the toxic gases emitted by halogen flame retardants or flame retardant materials in the event of fire, the harmful effects of halogens in daily use, and the environmental pollution caused by product recycling have received increasing attention. , thus promoting the development of halogen-free flame retardant systems. The existing halogen-free flame-retardant TPE materials mainly have the following main disadvantages: (1) Adding a large amount of inorganic fillers leads to an increase in material hardness, a decrease in mechanical properties, and poor resilience, which causes the loss of the el...
