Abstract

The invention discloses a preparation method of high-strength air filter paper, and relates to the technical field of air filter paper.The preparation method of the air filter paper comprises the following steps that 1, materials are prepared; 2, crushing the raw materials; step 3, processing the slurry; 4, shaping the filter paper; and 5, drying the filter paper. Through the arrangement of the crushing device, raw materials can be crushed in the preparation process of the filter paper, so that the raw materials are more convenient to pulp, the prepared pulp is better, and meanwhile, an active additive is added in the preparation process of the air filter paper, so that the quality of the air filter paper is improved. According to the air filter paper, the strength of the air filter paper can be improved, and the flame retardant mixed liquid and the antibacterial coating are arranged, so that the antibacterial and flame-retardant properties of the air filter paper can be improved, the use effect of the air filter paper is better, and the service life of the air filter paper is prolonged.

Description

technical field [0001] The invention relates to the technical field, in particular to a preparation method of high-strength air filter paper. Background technique [0002] In addition to oxygen and hydrogen, the air also contains dust, sand, bacteria and other harmful substances. Under some special environmental requirements, the air needs to be filtered to achieve the purpose of filtering the air. Air filter paper is a commonly used air filter material. . [0003] The following problems exist for the prior art: [0004] 1. When the existing air filter paper is processed and produced, the production process of the air filter paper is relatively cumbersome, and the produced filter paper has low strength when used, and its antibacterial and flame retardant properties are poor, thereby reducing the cost of air filter paper. The service life of air filter paper; [0005] 2. When the existing air filter paper is processed and produced, the raw materials need to be pulverized a...
