Abstract

The invention relates to a high-temperature filter felt impregnating compound with high temperature resistance and antistatic property, which is particularly suitable for a basalt fiber filter felt. The invention aims to provide a high temperature-resistant and antistatic impregnating agent for the basalt fiber filter felt to solve the problem that the working environment of the basalt fiber filter felt is severe. The technical scheme is that: the impregnating agent for the basalt fiber filter felt comprises the following components in percentage by weight: 5 to 6 percent of graphite emulsion with the solid content of 20 percent, 8 to 10 percent of PTFE solution with the solid content of 60 percent, 4 to 6 percent of silicone emulsion with the solid content of 60 percent, 3 to 5 percent of polyacrylate with the solid content of 30 percent, and the balance of water. After the impregnating compound is coated on the basalt fiber filter felt, the basalt fiber filter felt has good high temperature resistance and antistatic property. Actual detection proves that the heat loss of the basalt fiber filter felt produced by the formula is greatly reduced, and the product performance is greatly improved.

Description

technical field [0001] The invention relates to a high-temperature filter felt wetting agent with high temperature resistance and antistatic performance, which is especially suitable for basalt fiber filter felt. Background technique [0002] At present, basalt fiber filter felt is a brand-new filter material, and there is no special sizing agent for post-treatment. Because basalt fiber filter felt is generally used in transportation, construction, petrochemical and other fields, the working environment is relatively harsh, and the performance requirements for high temperature resistance and anti-static performance are relatively high. Therefore, a sizing agent is needed to improve the high temperature resistance and antistatic performance of the basalt fiber filter felt and prolong its service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a basalt fiber filter felt wetting agent with high temperature re...
