Problems solved by technology

[0002] As a high-end special paper for medical use, medical dialysis paper plays an indispensable key role in the treatment of some diseases and the packaging of medical equipment. However, due to the high price of imported dialysis paper, domestic The performance of dialysis paper is difficult to meet the standard, so that the high-end dialysis paper industry in China has been facing the situation that the supply is seriously less than the demand, which also makes low-quality dialysis paper often cause hidden dangers and even medical accidents during the treatment process due to performance problems

Abstract

The invention discloses a processing method for multilayer special medical dialyzing base paper. A base paper is composed of at least one surface layer, a middle layer, a bottom layer and an adhesive layer, wherein the surface layer is prepared from alkali-free chopped glass fibers and needlebush fibers; the middle layer is prepared from the alkali-free chopped glass fibers and hollow kieselguhr mineral fibers; the bottom layer is prepared by blending of the needlebush fibers, manila hemp fibers and 1414 aramid chopped fibers; and the multilayer special medical dialyzing base paper is prepared after the after-treatment. According to the processing method for the multilayer special medical dialyzing base paper disclosed by the invention, the framework glass fibers and needlebush pulp capable of promoting the strength of the medical dialyzing paper, natural sterile jute fibers and heat-insulating electric-resisting aramid fibers are selected for preparing into the multilayer special medical dialyzing base paper through blending, so that the toughness, strength and sterile grade of the finished paper are greatly promoted, the quality and grade of the domestic special medical dialyzing base paper are obviously promoted, the medical accident caused by unqualified dialyzing paper quality in the use process can be reduced and the multilayer special medical dialyzing base paper has higher use potential and value.
