High temperature resistant adhesive for automobile filter

Abstract

The invention relates to a high-temperature resistant adhesive for a filter cleaner of an automobile. The adhesive comprises the following raw materials in percentage by weight: 13 to 16 percent of polyvinyl chloride (PVC) resin, 19 to 22 percent of dioctyl phthalate, 2 to 3 percent of epoxidized soybean oil, 55 to 60 percent of calcium carbonate, 0.2 to 1 percent of liquid calcium zinc heat stabilizer, 2 to 5 percent of thermosetting phenolic resin, 0.3 to 1 percent of antioxidant, 1 to 2 percent of thixotropic agent and 0 to 2 percent of white oil. In the high-temperature resistant adhesive, phenolic resin modified polyvinyl chloride is adopted, the thermosetting phenolic resin has high infiltration capacity, so the adhesive is diffused and infiltrated to the surface of a bonding material fully to promote Brownian movement to make polar groups or chain knots on two interfaces get close to each other; and when the distance between the adhesive and adherend molecules is between 5 and 10 angstroms, mutually-attractive force is formed among interface molecules, and the distance among the molecules is further shortened to the maximum stable state, so the adhesive force of the adhesive can be enhanced; and the phenolic resin has the characteristics of high heat resistance, flame retardance and the like, so that the high-temperature resistant performance of the adhesive and filter cleaner products is enhanced.

Description

Technical field: [0001] The invention relates to the technical field of filters and adhesives, in particular to a high-temperature-resistant adhesive for automobile filters. Background technique: [0002] Oil, fuel, and air filters are used to filter out mechanical impurities in the engine oil, fuel, and air, and to protect the moving parts of the engine crankshaft, the precision coupling of the fuel injection system, and the piston rings of the cylinder liner from abnormal occurrences. Wear is an important accessory (attachment) that enables the engine's economic indicators, power indicators, reliability and emission indicators to function normally. 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. Products with unqualified original filtration efficiency cannot effectively filter out dust and impurities harm...
