Abstract

The invention discloses a PTC heating material for a toilet seat and a preparation method of the PTC heating material. According to the invention, an organic polymer is used as a support material; theconductive filler is added into the organic polymer, and the Curie temperature of the prepared PTC heating material is -10 to 40 DEG C by adjusting the formula of each component, so that the preparedPTC heating material can be used for heating control of the toilet seat, and the prepared PTC heating material has relatively good flexibility and is prevented from being broken due to temperature change.

Description

technical field [0001] The invention relates to the technical field of PTC materials, in particular to a PTC heating material for a toilet seat and a preparation method thereof. Background technique [0002] As a heating material for smart toilet rings, PTC materials are more and more widely used in the production of smart toilet rings. PTC materials have unique electrothermal characteristics, that is, the resistance value remains basically unchanged or only changes slightly when the temperature is low, and when the temperature exceeds the Curie temperature, the resistance value of the material increases sharply with the increase of temperature. High, this feature can avoid scalding the user due to excessive temperature rise during the heating process of the toilet seat. [0003] However, the existing PTC materials have the following problems in the application process of smart toilet seat: [0004] 1. Most of the existing PTC materials are used in the form of PTC ceramic ...
