Abstract

The invention discloses a formula of color changeable modified polytetrafluoroethylene. The color changeable modified polytetrafluoroethylene comprises modified polytetrafluoroethylene synthetic resin, a filling agent, a plasticizing agent, a dispersing agent, an antioxygen, a fire retarding agent and a thermosensitive color changing agent, wherein the filling agent is a mixture of wood powder and mica powder, the plasticizing agent is triphenyl phosphate, the dispersing agent is barium stearate, the antioxygen is hindered phenol, the fire retarding agent is a mixture of antimonous oxide and tetrabromophthalic anhydride, and the thermosensitive color changing agent is lead butyrate. Through adoption of the manner, the prepared color changeable modified polytetrafluoroethylene is strong in high temperature resistance, strong in flame resistance and low in cost, has the high-temperature color changing warning function, and is relatively high in safety.

Description

technical field [0001] The invention relates to the field of plastic formulations, in particular to a color-changing modified polytetrafluoroethylene formulation. Background technique [0002] PTFE has strong high temperature resistance, and can withstand high temperatures up to 300 degrees Celsius in a short period of time. Although it can be used stably and continuously between 240 degrees Celsius and 260 degrees Celsius, and has certain thermal stability, the safety hazard cannot be absolutely guaranteed, and the high tolerance under high temperature has become one of the adverse factors that hinder the timely discovery of safety hazards. One, causing problems such as untimely fire detection. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a color-changing modified polytetrafluoroethylene formula, so that the prepared color-changing modified polytetrafluoroethylene has strong high temperature resistance,...
