Abstract

The invention discloses a special calcium-based powder modifying device for adhesive, which comprises a grinder and a kneader connected with the grinder, and also includes a mixing device arranged between the grinder and the kneader, the mixing device includes a mixing chamber, modifier nozzle, hot high-pressure gas nozzle, powder nozzle, the powder nozzle is located in the upper part of the mixing chamber and one end extends into the mixing chamber; the invention also discloses a special calcium-based powder modified The method includes a modification step using a special calcium-based powder modification device for adhesives. The present invention can make the modifier on the surface of the powder more uniform by mixing the modifier and the powder before kneading, and at the same time, ensure that the powder The adhesion rate of the body surface modifier, the powder is fully attached to the modifier and then enters the kneader for kneading modification to ensure the quality of the powder and can effectively improve the activation degree of the powder. It has the advantages of simple process, improved The advantage of the activation degree of powder after curing is greater than 90%.

Description

technical field [0001] The invention relates to a special calcium-based powder modification device for adhesives, and also relates to a modification method, which belongs to the technical field of calcium carbonate modification. Background technique [0002] Calcium carbonate has the advantages of low price, non-irritating, non-toxic, good color and high whiteness. In the adhesive industry, calcium carbonate is one of the most widely used inorganic fillers. [0003] At present, the output and market share of heavy calcium carbonate in my country are far greater than that of light calcium carbonate, but the most advanced grinding technology in the world can only make the particle size of heavy calcium carbonate reach about 1 μm. This scale of heavy calcium carbonate filled in the resin matrix can only play a strengthening role, and cannot achieve the effect of toughening and functionalization. Therefore, in order to further expand the application fields and prospects of heav...
