Problems solved by technology

It has been more than half a century since the first batch of oil filter paper was produced in the United States. Since the first batch of products, alcohol-soluble phenolic resin has been used as the impregnated resin for reinforcing filter paper. Alcohol-soluble phenolic resin has a large amount of solvent and potential danger during use. , Solvent recovery difficulties and other problems, based on these reasons, domestic and foreign are constantly committed to research and development of new impregnating resin systems

Abstract

The invention discloses impregnating resin for filter paper of an engine oil filter element device and relates to the technical field of filter element devices. The impregnating resin is prepared fromthe following components: water-soluble phenolic resin, dihydromethyl propionic acid, modified nano silicon dioxide, epoxy resin, dimethyl fumarate, dimethyl itaconate, modified sodium lignosulphonate and a plasticizer. The filter paper impregnated with the resin can keep good filtering performance; the impregnating resin does not cause a pore-blocking phenomenon on pores of the filter paper.

Description

technical field [0001] The invention belongs to the technical field of filter elements, and in particular relates to an impregnating resin for filter paper of an oil filter element. Background technique [0002] Oil filter paper, also known as lubricating oil filter paper, is used to remove impurities such as dust, metal particles, carbon deposits, and bituminous coal particles in the oil to keep the engine clean and prevent machine wear. In recent years, due to the rapid development of my country's automobile industry, the amount of oil filter paper has gradually expanded. It has been more than half a century since the first batch of oil filter paper was produced in the United States. Since the first batch of products, alcohol-soluble phenolic resin has been used as the impregnated resin for reinforcing filter paper. Alcohol-soluble phenolic resin has a large amount of solvent and potential danger during use. , Solvent recovery difficulties and other issues, based on these...
