Problems solved by technology

However, due to the expansion of application sites, the requirements for high temperature resistance, toughness, hardness, etc. of the glue are getting higher and higher; usually, the high temperature resistant polyester hot melt adhesive has a high viscosity, which is not conducive to the coating operation, and is difficult to infiltrate. sticky substance, poor bond strength
And the anti-yellowing performance is not good, the color difference changes greatly during the mixing process, and it is difficult to meet the places that require high hardness in automotive interiors, etc., which brings inconvenience to people's use.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high and low temperature resistant APAO hot melt adhesive for filter production and a preparation method thereof. Background technique [0002] As the country's environmental protection requirements become more and more stringent, the control of air PM2.5 in various regions is also strict, and people's living standards, everyone has high requirements for control quality. At present, various air purifiers, vacuum cleaners, air conditioners, and water purifiers , automobiles, etc. are becoming more and more widely used. At the same time, it needs to be able to be used normally in various environments, such as the high temperature resistance requirements in automobiles, and vacuum cleaners also need to be used in high or low temperature environments. In these products, filters are required, so it is also required when the filter is produced The hot melt adhesive used can withst...
