Problems solved by technology

[0005] At the same time, it is easy to breed fungi in a damp environment, which will cause the protected environment to pass through the protective layer in a long-term high-pressure air volume and enter the protected environment, causing environmental pollution. The service life of filter paper is greatly reduced

Abstract

The invention discloses antibacterial type air filter paper and a production process thereof. The antibacterial type air filter paper is prepared from the following components in parts by weight: 40 to 60 parts of plant fiber, 10 to 15 parts of a fiber binding agent, 25 to 40 parts of active carbon, 8 to 15 parts of a surfactant, 1 to 2 parts of a glyoxal modified polyacrylamide wet strength agent and 15 to 25 parts of latex. By adding the surfactant into the production process, the surface tension of the filter paper can be effectively reduced; the powdery active carbon is added into paper pulp at a certain ratio and a mixture is subjected to papermaking to obtain the antibacterial type air filter paper; the strength problem of paper sheets is solved by adopting the latex through a surface treatment manner; good parameters including air permeability, adsorptivity and filtering precision of the active carbon filter paper are guaranteed.

Description

technical field [0001] The invention relates to a production process of filter paper, in particular to an antibacterial air filter paper and a production process thereof. Background technique [0002] In addition to oxygen and hydrogen, the air also contains dust, sand, bacteria and other harmful substances. In some special environments, it is necessary to filter the air, such as automobile engines, precision instrument production workshops, laboratories, operating rooms, etc. Air filter material is used to achieve the purpose of filtering air. Air filter paper is one of the commonly used air filter materials. [0003] Functional air filter material is a research hotspot in recent years. It is a filter material developed for specific industries such as high temperature resistance, corrosion resistance, antistatic, water repellency, oil repellency, flame retardant, and removal of harmful gases, such as flame retardant air filter Paper. The application of nanotechnology to ...
