Abstract

The invention discloses an organic solidification curing resistor slurry and a preparation method thereof. The organic solidification curing resistor slurry comprises a resistor function phase and an organic carrier, wherein the resistor function phase comprises super fine silver powder and super fine silicon carbide powder, the organic carrier comprises high temperature prevention resin, a high-molecular fire retardant, a solvent and an additive, the additive comprises a liquid antifoaming agent, a liquid levelling agent, a liquid anti-settling agent, a thixotropic agent, an eleaostearic acid salt heat stabilizer and an infiltration dispersant. The organic solidification curing resistor slurry can effectively solve a technical problem that thinning, lightening or specialization are not easy to realize in the prior art, 130-200 DEG C curing can be further realized, and the characteristic that the organic solidification curing resistor slurry can be used in relatively high temperature of 300 DEG C can be realized. The preparation method comprises steps that a, the resistor function phase is prepared; b, additives are prepared; c, the organic carrier is prepared; d, pre-mixing of the resistor function phase and the organic carrier is carried out; and e, a three-roller grinder is employed for grinding. Through the method, the organic solidification curing resistor slurry can be effectively prepared.

Description

technical field [0001] The invention relates to the technical field of organic electrothermal materials for heaters, in particular to an organic cured resistance slurry and a preparation method thereof. Background technique [0002] The heating method of ordinary heaters uses traditional nickel-chromium alloy and other resistance wires or resistance films as heating materials. The thinning, miniaturization, and specialization of the device put forward higher requirements. For the traditional nickel-chromium alloy resistance wire or resistance film, it has been unable to meet the technical development requirements. [0003] It should be further pointed out that for existing resistance wire heaters or resistance film heaters, there are the following disadvantages, specifically: [0004] 1. The manufacturing process of resistance wire or film is complicated, the production cycle is long, and the production cost is high; [0005] 2. The manufacturing process of the heating pl...
