Green energy-saving wearproof cold-resistant and flame retardant thermoplastic rubber and preparation method thereof

Abstract

The invention discloses a green energy-saving wearproof cold-resistant and flame retardant thermoplastic rubber and a preparation method thereof. An SIBR / PP / SBS / TPU polymer composite system, wearproof, loss reduction factor and good cold-resistant assistant materials and a halogen-free and antimony-free compound flame-retardant system are adopted as the main components, and preparation of SIBR masterbatch, silane modification treatment of a flame retardant, high-speed mixing pre-plasticization, internal mixer and extruder combined dynamic vulcanization and other processes are carried out. Under the conditions of an internal mixer rotation speed of 40rpm and a temperature of 160DEG C-165DEG C, dynamic vulcanization is carried out for 2-3min, then dynamic vulcanization by an extruder is conducted, and under the conditions of a screw rotation speed of 50-70rpm and a temperature of 165DEG C-180DEG C, dynamic vulcanization is conducted for 5-7min so as to obtain the thermoplastic rubber. Inaddition to the basic performance of thermoplastic rubber, the thermoplastic rubber provided by the invention also has excellent energy-saving, environmental protection, flame retardant, cold-resistant and other properties, and at the same time has the advantages of simple process, easy manufacturing, and low production cost.

Description

technical field [0001] The invention relates to the technical field of thermoplastic rubber, in particular to a green, energy-saving, wear-resistant, cold-resistant, flame-retardant thermoplastic rubber and a preparation method thereof. Background technique [0002] Low-smoke halogen-free flame-retardant rubber technology has become an important part of high-clean environmental protection technology, and economically developed countries have revised their original flame-retardant standards. In early 2003, the European Union promulgated the ROHS Directive, WEEE Directive and new flame retardant regulations, making more and more countries restrict or prohibit the use of halogenated flame retardants. Developed countries have always attached great importance to the research and development and promotion of low-smoke, low-halogen, and flame-retardant rubber materials, especially in important buildings and facilities that are relatively closed or crowded, such as coal mines, build...

AI Technical Summary

Problems solved by technology

There are currently outstanding problems in domestic research on low-smoke halogen-free rubber: first, there are few varieties, second, poor mechanical properties, and third, the product has poor weather resistance and can only be used at room temperature. Affect

my country's research on low rolling resistance rubber technology is relatively late. At present, there are many studies on low rolling resistance tires, but there are few reports on green energy-saving, wear-resistant, cold-resistant, flame-retardant thermoplastic rubber products and technologies.
