Abstract

The invention discloses a rubing grain joint filler, which is prepared from the following ingredients including vinyl acetate resin, acrylic acid resin, chlorinated rubber, polycarbamate and fillers.

Description

technical field [0001] The invention relates to the field of joint materials, in particular to a chrome corundum joint material. Background technique [0002] The composition of red corundum is mainly α-alumina, also called chromium corundum, the main mineral composition is α-Al2O3-Cr2O3 solid solution, the secondary mineral composition is a small amount of composite spinel (or no composite spinel), and the content of chromium oxide is 1% to 30% of refractory bricks. There are two types of cast chrome corundum bricks and sintered chrome corundum bricks. In general, chrome corundum bricks refer to sintered chrome corundum bricks. Using α-Al2O3 as raw material, add appropriate amount of chromium oxide powder and chromium corundum clinker powder, after molding, it is fired at high temperature. The chromium oxide content of sintered chromium corundum bricks is generally lower than that of fused cast chromium corundum bricks. It can also be prepared by slurry pouring method. ...
