Automobile air filter assembly

Abstract

The invention discloses an automobile air filter assembly, and relates to the technical field of filters. The automobile air filter assembly comprises a filter upper shell, an air outlet, an air inlet and a filter lower shell; the air outlet is arranged on one side of the bottom of the filter lower shell, the filter upper shell is arranged above the filter lower shell, the air inlet is arranged on one side of the top of the filter upper shell, and a filter element is mounted at the top of the filter lower shell. The problems that the mechanical property of a filter element of an existing air filter is fragile, the performance of a paper-based material is poor, and in the working process of an engine, due to the fact that inflammables are inhaled or tempering occurs, the filter element is burnt are solved. A flame-retardant layer and a modified organic silicon reinforced filter paper layer are compounded, so that the flexibility and tensile strength of the filter element are improved, and the mechanical property and flame retardance of the air filter are improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an automobile air filter assembly. Background technique [0002] The function of the air filter is to filter out impurities in the air entering the engine intake system, protect the cylinder of the engine, avoid early wear, and ensure the normal wear speed of the engine. It is a key functional component to ensure the normal service life of the engine. Air filter The filter is composed of two parts, the filter element and the housing. The filter element achieves the purpose of purifying the air by changing the flow direction of the air or passing the air through the filter element with micropores; [0003] However, the mechanical properties of the filter element of the currently used air filter are relatively brittle, and the performance of the paper-based material is not good. In addition, during the operation of the engine, combustibles may be inhaled or backfired, and the filte...

Problems solved by technology

[0006] (1) By adding dry chloroplatinic acid to the distilled and dried isopropanol solution to obtain a catalyst, adding glycidyl methacrylate, an inert solvent toluene and a catalyst in a three-necked flask, and adding hydrogen-containing silicone oil dropwise to obtain For intermediate A, add phenol, sodium hydroxide and deionized water to a three-necked flask, add formaldehyde dropwise, and add 2,4-xylenol to obtain intermediate B, add intermediate B to distilled water, and stir Next, add intermediate A to obtain product C, add deionized water to product C, impregnate the filter paper base paper, and dry to obtain the modified silicone reinforced filter paper layer. By using the modified silicone reinforced filter paper layer, It solves the problem that the mechanical properties of the filter element of the existing air filter are brittle and the performance of the paper-based material is not good;
