Abstract

The invention discloses a preparation method of an organic carrier material for high-power resistor paste. The preparation method particularly comprises the following preparation steps: (1) mixing terpilenol and a thickening agent, heating to 70 to 80 DEG C, stirring for 15 to 20 minutes and continuously heating to 90 to 100 DEG C; (2) adding dioctyl phthalate and diethylene glycol butyl ether acetate into the mixed solution in the step (1), stirring for 10 to 15 minutes, performing ultrasonic treatment for 5 to 8 minutes and cooling to 60 to 70 DEG C; (3) adding a surfactant, a rheological agent and a thixotropic agent into the mixed solution which is cooled in the step (2), stirring for 10 to 15 minutes and naturally cooling. The preparation method has the beneficial effects that by aiming at the actual characteristics of the high-power resistance work environment, the prepared formula can guarantee that other components of the resistor paste can be effectively mixed and can also guarantee the work stability of the formed resistor under the high-power electrical environment.

Description

technical field [0001] The invention relates to the technical field of resistance slurry preparation, in particular to a method for preparing an organic carrier for high-power resistance slurry. Background technique [0002] Resistor paste is the core raw material for manufacturing resistors, and the difference in its properties determines the performance and use of the resistor itself. The resistance paste is mainly composed of three parts: organic carrier material, glass phase and conductive phase. The organic carrier material can make the slurry obtain better fluid performance as a whole, so as to facilitate the subsequent printing process, make the resistance film more uniform, and make the film more uniform. Performance is better. [0003] In order to adapt to the high-power circuit environment, the resistance paste of high-power resistors has made a large change in its own formula. If the ordinary organic carrier material is used, it cannot meet its film-forming requi...
