Abstract

The invention discloses a mixed paper pulp filter paper and a preparation method thereof. The filter paper comprises following raw materials in parts by weight: 40 to 50 parts of rice straw pulp, 30 to 40 parts of wood pulp, 10 to 20 parts of bamboo pulp, 5 to 6 parts of styrene-acrylic emulsion, 10 to 12 parts of mineral fiber, 8 to 10 parts of polyester fiber, 1 to 2 parts of potassium tetraborate, 2 to 3 parts of alumina powder, 1 to 2 parts of dioctyl sebacate, 3 to 4 parts of pentaerythritol, 2 to 3 parts of sodium hexametaphosphate, 0.8 to 1 part of poly-4-methyl-1-amylene, 0.2 to 0.3 part of triethanolamine, 12 to 20 parts of chitosan, 3 to 4 parts of glycerin, 1 to 2 parts of ammonium molybdate, 4 to 5 parts of absolute ethyl alcohol, 0.1 to 0.2 part of dibenzoyl peroxide, 0.6 to 1 part of N-(beta-aminoethyl)-gamma- aminopropyltrimethoxysilane, and a right amount of water. The preparation method adopts mixed paper pulp as the raw material, therefore the production cost is reduced, at the same time, characteristics of various paper pulps can be combined, and more excellent filter papers are produced.

Description

technical field [0001] The invention mainly relates to a filter paper, in particular to a filter paper for a mixed pulp filter and a preparation method thereof. Background technique [0002] The filter is an important part of the engine. Its function is to filter out particles such as dust and mechanical impurities in the air, diesel oil, and engine oil entering the engine, so as to reduce the engine cylinder liner piston ring, crankshaft connecting rod kinematic pair and high-pressure oil pump plunger. Wear of even parts, optimize the combustion process of the engine, and reduce the emission of organic pollutants such as carbon monoxide. The traditional production of filter paper has problems such as low filtration performance, short service life, and unstable quality of filter paper, which greatly limits the improvement of filter filtration efficiency and also affects the improvement of engine performance. It is difficult to meet the current requirements of people....
