Filter core end cover for methanol filter and preparation method thereof

Abstract

The invention discloses a filter core end cover for a methanol filter and a preparation method thereof. The filter core end cover is prepared from following raw materials in parts by weight: 45 to 55parts of nylon 6 resin, 6 to 8 parts of ethylene-vinyl acetate copolymer, 8 to 12 parts of glass fiber, 0.2 to 0.4 part of antioxidant, 0.1 to 0.3 part of lubricant, 0.4 to 0.6 part of heat stabilizer, and 2 to 4 parts of filler. Nylon 6 is taken as the main raw material of the filter core end cover, is very stable in methanol and water, and will not be dissolved or carry out chemical reactions, thus the firmness of the connection between filter paper and the end cover is guaranteed, the end cover is fixed on a filter material through sweat soldering, a conventional glue cementing method is not used, by adding ethylene-vinyl acetate copolymer, the sweat soldering performance of nylon 6 is enhanced, and the fastness of soldering between the end cover and the filter material is guaranteed.

Description

technical field [0001] The invention relates to the technical field of methanol filters, in particular to a filter element end cover for a methanol filter and a preparation method thereof. Background technique [0002] The increasingly severe environmental protection situation, the potential risk of energy crisis and the needs of the national energy security strategy make the development of alternative fuels for burning methanol very urgent. Methanol is an organic fuel with physical and chemical properties similar to gasoline, which can be produced from natural gas, coal, and biological raw materials. Methanol has high thermal efficiency and less pollutants released by combustion, which can meet the power and emission requirements of current engines. At the same time, methanol in a liquid state at room temperature is convenient for transportation and distribution, and is suitable for popularization and application. Therefore, methanol is very suitable as an alternative ene...

Problems solved by technology

On the one hand, whether it is a one-component glue or a two-component glue, the resin component in the glue will be degraded in the methanol solution, and the filter paper and the end cap are easy to separate; on the other hand, methanol and water in methanol will affect the metal surface The galvanized layer plays a role in corrosion and anti-chemical reaction, thus endangering the engine
