Calcium sulfate whiskers in the treatment liquid are added as a matrix, and the whisker structure supports the nepheline structure. Silane coupling agent KH550 and sodium lignin sulfonate solution are then blended.

The performance effect of the product obtained by the specific method of the present invention is the most significant, and the additive treatment liquid of the present invention has specificity. The performance effect is the most significant when the technical solution of the present invention is adopted; In addition, the yttrium-zinc compound is replaced by nano zinc oxide, and the antibacterial performance of the product tends to deteriorate under normal conditions and under cold and heat resistant conditions.
