Abstract

The invention discloses an air filter paper for automobiles with good water resistance, moisture resistance and burst resistance, which is characterized in that it is prepared from the following raw materials in parts by weight: coniferous wood pulp 45‑48, cotton pulp 47‑51, glass fiber 3‑ 4. Crushed wasabi 2‑3, calcium peroxide 1‑2, paraffin emulsion 6‑8, dimethyl silicone oil 0.2‑0.3, n-dodecyltrimethoxysilane 0.6‑0.9, zinc oxide 2‑3, dioxide Manganese 2‑3, Tianqing glue 0.4‑0.6, sodium alginate 0.2‑0.4, polyester polyol 3‑4, emulsifier OP‑10 0.3‑0.5, auxiliary agent 1‑2, appropriate amount of water; the invention is strong and durable, Water and moisture resistance, good burst resistance, long service life, adding manganese dioxide catalyst, can effectively evolve toxic substances in the air; adding additives, increasing the porosity of filter paper, more evenly dispersed adsorption components, excellent water resistance, Improved filtering performance.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to an air filter paper for automobiles with good water resistance, moisture resistance and burst resistance and a preparation method thereof. Background technique [0002] Automobile air filter paper is the core material for manufacturing automobile engine air filters. Since the air filter is located in the intake system of the engine, and the engine usually emits a lot of heat when it is working, it is generally hoped that this air filter medium has good performance. Excellent filtration performance and high filtration efficiency, as well as certain high temperature resistance, water resistance and burst resistance. The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency and can only filter out 50-60% of the impurities in the oil; in addition, when the air filter paper is used in rainy and high humidity areas, the pape...

AI Technical Summary

Problems solved by technology

The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency and can only filter out 50-60% of the impurities in the oil; in addition, when the air filter paper is used in rainy and high humidity areas, the paper filter layer After absorbing moisture, it will swell, which will reduce the pore size and porosity of the filter paper, resulting in the increase of filter resistance and the reduction of vehicle power. It also has the disadvantages of poor high temperature resistance, low tensile strength, and poor burst resistance, which limits the Service life of filter paper
