Problems solved by technology

Greenhouse-cured adhesives can be used for air filters, and greenhouse-cured adhesives are not suitable for engine oil and fuel filters due to their high operating temperature. Heat-cured adhesives are often used. In order to make fuel burn more fully and reduce vehicle exhaust emissions, Part of methanol or ethanol is also added to gasoline. These alcohols can dissolve and extract certain components of the adhesive, resulting in a decrease in the bonding strength of the filter element and the end cover or even falling off, causing the filter to be scrapped ahead of time, resulting in engine failure. Early wear, shortening its service life
At present, the oil filter curing glue used in China has the following disadvantages: 1. Foaming holes in the cured glue, and the glue is not dense; 2. Poor adhesion; 3. Big smoke and heavy smell during the production process; 4. Rubber material rough, poor appearance

Abstract

The invention discloses an oil filter adhesive. The adhesive is prepared from 3-4 parts of a sulfonated modified graphite powder / silicon micropowder composite, 15-25 parts of silane modified epoxy resin, 5-8 parts of butyl rubber, 1-2 parts of diaminodiphenyl methane, 0.5-1 part of bis(2-ethylhexyl) phthalate, 1-1.5 parts of a silane coupling agent KH-550, 0.4-0.7 part of an initiator, 0.3-0.5 part of a stabilizer and 0.4-0.6 part of an emulsifier. The prepared oil filter adhesive has the advantages that the adhesive has high adhesion performance through the synergistic effect of all components; meanwhile, the corrosion resistance is high, the high-temperature resistance is excellent, after curing, the surface is flat, the toughness is good, the service life is long, and the sealing performance of a filter is ensured.

Description

technical field [0001] The invention belongs to the technical field of filter processing, and in particular relates to an oil filter adhesive. Background technique [0002] The filter is one of the key components to ensure the durability and reliability of the engine. It is usually divided into air, oil and fuel filters. The oil filter is also called the oil filter, which is used to remove dust and metal particles in the oil. , Carbon deposits and soot particles and other impurities to protect the engine. With the gradual implementation of emission regulations, the advancement of engine technology has put forward new and higher requirements for filter products, which shows the importance of filters for engine matching. With the development of science and technology, the structure of filters tends to be unified gradually, and paper filters are mostly used for filtering. [0003] The filter adhesive is used for the bonding of the paper filter element of the filter and the me...
