Embodiment 1

[0034] A conductive ink for regulating power, comprising the following components:

[0035]

[0036] The preparation method of the conductive ink for regulating power is as follows:

[0037] 1. Mix highly conductive carbon black into highly crystalline high-density polyethylene, and make granules after thorough mixing at a high temperature of 200°C.

[0038] 2. Cross-link the prepared particles through nuclear irradiation, so that carbon black and high-density polyethylene can be stably cross-linked and prevent carbon black from migrating. If the carbon black migration will cause the product to undergo irreversible changes in electrical conductivity during high and low temperature cycles.

[0039] 3. Pulverize the cross-linked particles with a pulverizer to achieve an average particle size of less than 1 mm.

[0040] 4. Grind the particles with an average particle size of less than 1 mm to 0.2-200 microns with a jet mill.

[0041] 5. Put the pulverized micropowder into a...

Abstract

The invention relates to a conductive ink for regulating power as well as a preparation method and application of the conductive ink. The conductive ink comprises the following components in percentage by mass: 4-50% of conductive material, 8-30% of polyolefin jointing material, 40-86% of organic solvent and 2-15 parts of auxiliary material. The conductive ink for regulating power has the advantages of PTC (Positive Temperature Coefficient) function, automatic constant temperature, cost reduction because of temperature control element reduction, energy saving and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of ink materials, and in particular relates to a power-regulating conductive ink and its preparation method and application. 【Background technique】 [0002] Conductive ink is a special ink with conductive properties. It is a conductive composite material formed by dispersing conductive particles (silver, copper, carbon, etc.) in the binder. It is printed on the substrate and cured to form a film. Some effect. Conductive ink is an important electronic material and has a huge market in our country. [0003] Among them, the electric heating element made of conductive ink with adjustable power has the function of automatically increasing the resistance, reducing the current, and reducing the power as the temperature rises. It can greatly improve the temperature uniformity of the heating element, can generate heat quickly and with high power at low temperature, and can minimize the power when reaching the set...
