Abstract
The present invention relates to a method for manufacturing glass sealing material for insulating and sealing. The glass sealing material is especially used for insulating and sealing components, zero matching components, etc. of household electric appliance industry. The method has the steps that raw powders of lead oxide red, alumina, orthoboric acid and selenium dioxide are uniformly ground, are put in a crucible, are increased in temperature, and are put in water to be quenched; during dryness grinding, the quenched glass material is dried, and is ground into glass powder; an adhesive is added, the glass powder is formed, is increased in temperature after being sintered, and is cooled in a furnace to the room temperature. The temperatures in the raw material melting and sintering technological process and the temperature rise and insulating time are preferably selected, the effective volatilization of various kinds of impurities is well controlled, the technical index of products is enhanced, and the product purity is obviously enhanced.
