Problems solved by technology

[0004] Water-based adhesives have the advantages of solvent-free release, environmental friendliness, non-toxicity, safe use, and low cost. They are gradually becoming the mainstream product of synthetic adhesives. The current water-based adhesives are generally cured at room temperature and have poor initial viscosity. The adhesive layer is prone to stick back under high temperature conditions

Abstract

The invention relates to a hydrothermal activated adhesive for an engine oil filter as well as a preparation method of the hydrothermal activated adhesive. The hydrothermal activated adhesive comprises the following components in parts by weight: 60 to 100 parts of water-soluble alkyd resin, 30 to 60 parts of modified rosin resin, 1 to 6 parts of hydroxyl-alkylamine, 1 to 6 parts of a conditioner,5 to 20 parts of propylene glycol, 1 to 5 parts of a foam inhibitor, 1 to 6 parts of ethylene-bis-stearamide and 100 to 200 parts of water. The hydrothermal activated adhesive provided by the invention has high initial viscidity at low temperature, can further enhance the adhesion strength at high temperature, is not liable to cause after-tack, is stable in performance, is little influenced by temperature and humidity, and has excellent water resistance and heat resistance. In addition, the hydrothermal activated adhesive does not contain an organic solvent, avoids release of formaldehyde, and has the advantages of high performance, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of filter adhesives, in particular to a water-based heat-activated adhesive for oil filters and a preparation method thereof. Background technique [0002] During the working process of the automobile engine, metal wear debris, dust, carbon deposits and colloidal sediments oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and extend its service life. Common oil filters include spin-on oil filters and replaceable oil filters; among them, the spin-on oil filter has a complex structure, contains many parts, and has a cumbersome manufacturing process and high cost. The structure and manufacturing process of the replaceable oil filter are relatively simple, the cost is low, and the dosage is more environmentally friendly, so it has been widely used in...
