Method for adding feather fiber for making air filtering paper applied in automobile industry

Abstract

The invention discloses a method for adding feather fiber for making air filtering paper applied in the automobile industry. According to the method, hardwood pulp, softwood pulp and feather fiber pulp are mixed uniformly, a fast paper forming device is used for papermaking, then a paper blank is dried in a dryer, and an air filtering paper blank is prepared; styrene-acrylic emulsion and hydroxylsilicone oil emulsion are diluted by deionized water separately and then placed in soaking tanks respectively, the air filtering paper blank is soaked in the diluted styrene-acrylic emulsion at first,redundant emulsion on the paper blank is filtered off by a glue applying machine, and then the paper blank is dried on the dryer; then, the air filtering paper blank is placed into the diluted hydroxyl silicone oil emulsion for soaking, redundant emulsion on the paper is filtered off by the glue applying machine, then the paper blank is dried on a rotating drum type drier and put into a drying box for drying and solidification, and correspondingly the air filtering paper is prepared. The hydroxyl silicone oil emulsion can obviously improve the waterproof performance and dust holding capacityof the filtering paper. Since hydroxyl silicone oil has natural waterproof performance, the filtering paper has excellent waterproof performance, and especially through application of an adhesive structure, the dust holding capacity of the filtering paper is substantially increased.

Description

technical field [0001] The invention belongs to the field of filters, and in particular relates to a method for preparing air filter paper for the automobile industry by adding feather fibers. Background technique [0002] Automobile filter paper is a kind of special paper. Its special properties and uses determine that mixed fibers must be used to meet the requirements of filter paper. Feather is a low-carbon, environment-friendly and recyclable raw material. The invention applies feather fiber to automobile filter paper, which not only reduces the cost, but also improves the performance of the filter paper, and can make full use of resources, turning waste into treasure. [0003] The base paper of air filter paper for the automotive industry is mainly made of natural plant fibers. During the process of papermaking, almost no fillers and papermaking chemicals are added, and no pressing is performed. Therefore, the base paper of the filter paper has a loose structure, low bo...

Problems solved by technology

[0003] The base paper of air filter paper for the automotive industry is mainly made of natural plant fibers. During the process of papermaking, almost no fillers and papermaking chemicals are added, and no pressing is performed. Therefore, the base paper of the filter paper has a loose structure, low bonding strength between fibers, soft texture and water resistance. Poor performance, low strength, and various physical and chemical indicators can not meet the application requirements as the final product, so the filter paper base paper must be post-processed
