| titleOfInvention | A kind of flame retardant curing filter paper and preparation method thereof |
| abstract | The invention relates to the technical field of cured filter paper. In order to improve the flame retardant performance of the filter paper and meet the application requirements of the filter paper on the engine, the invention provides a flame retardant cured filter paper and a preparation method thereof. After being immersed in the liquid, it is taken out and heated and cured, and the base paper is made of composite wood pulp, polyetherimide powder, polyethyleneimine, melamine resin, compatibilizer, succinimide ashless dispersant and defoamer. The dipping solution is made of thermosetting phenolic resin, PCTA copolymer, cross-linking agent, flame retardant, styrene-acrylic emulsion, methanol, isopropyl acetate and organosilicon alkoxide sodium salt. The flame-retardant cured filter paper of the invention has strong flame-retardant performance, high temperature resistance, strong dimensional stability at high temperature, and high strength and filtration precision of the filter paper, the preparation method has few steps, the process is simple, and the operation is easier, and the obtained cured filter paper is suitable for use as an engine The filter element of the air filter is used. |
