Abstract

The invention relates to an insulating glass dielectric slurry for 430 stainless steel and a preparation method thereof. The current insulating glass paste generally has the problem that the thermal expansion coefficient does not match the metal of the heating element, which causes the coating to crack or fall off during use; and the pressure resistance is relatively poor. The raw material composition and weight ratio of the insulating glass dielectric slurry for 430 stainless steel of the present invention are: BaCO3 30-80 parts; Al2O3: 0-10 parts; CaCO3: 0-10 parts; SiO2: 40-50 parts; H3BO3: 0 ~5 parts; TiO2: 5~10 parts; the preparation steps are: batching→mixing→smelting→quenching→drying→ball milling→sieving→testing→weighing and packaging. The invention adopts environment-friendly materials, has excellent electrical performance, strong pressure resistance, and low manufacturing cost, effectively solves the problem of thermal expansion coefficient mismatch between insulating glass dielectric slurry and metal substrate, and has good market prospect.

Description

technical field [0001] The invention relates to an insulating glass dielectric slurry for 430 stainless steel and a preparation method thereof. Background technique [0002] The heater with 430 stainless steel as the substrate can print insulating glass dielectric paste on the surface of the substrate, and print the circuit on the insulating glass after sintering to form a high-power circuit. The core technology of 430 stainless steel heater is the preparation of insulating glass paste. The current insulating glass paste contains a large amount of heavy metal lead, which is extremely harmful to the environment and human health; the expansion coefficient of 430 stainless steel is 10.5ppm, but the thermal expansion coefficient of each component in the insulating glass paste is relatively low. , there is a common problem that the thermal expansion coefficient does not match the substrate, resulting in cracking or falling off of the coating during use, short service life, poor ...
