AI Technical Summary

Technical Problem

Existing thermoplastic elastomers exhibit unheat resistance and uneven heat resistance in high and low temperature environments, and the traditional modifier addition method results in unclear hot melt temperature zones, increasing energy consumption and equipment complexity.

Method used

Use the monomer independent hot -melt method to add a modified agent, and use the efficient pre -mixing at the main outlet location. Use parallel propeller and split heating structure to independently control the heating temperature of the modifier and the main material to ensure the modifier agent to ensure the modifier agent. Uniformly distributed.

Benefits of technology

It improves the high temperature resistance and low temperature resistance of thermoplastic elastic body, reduces energy consumption, simplifies the equipment structure, and ensures the uniform distribution of the modified agent, and improves the quality control of the finished product.

Abstract

The invention discloses a process for preparing a high-temperature-resistant flame-retardant thermoplastic elastomer. The process comprises the following steps: weighing materials, feeding the materials, performing hot melting on main materials, adding a modifier, performing modified hot melting on monomers, feeding and uniformly mixing the monomers, and extruding the materials. The main materials, the auxiliary materials and the modifier are weighed according to the preparation proportion, the main materials are preferably prepared by blending SEBS particles and white mineral oil, and the types of the auxiliary materials include but not limited to plasticizers, antioxidants and fillers. A single body independent hot melting mode is adopted, the process and equipment are improved, specifically, a single modifier hot melting mode is adopted, efficient premixing is carried out at the position of a main material outlet, and the problems that hot melting temperature zones are not clear due to the fact that modifiers are directly added into main materials, and meanwhile the requirement for the heating temperature of a main channel is high are solved.
