Polyolefin hot melt adhesive for filter and preparation method thereof

The invention discloses a polyolefin hot melt adhesive for a filter and a preparation method of the polyolefin hot melt adhesive, and belongs to the technical field of hot melt adhesives for filters, the polyolefin hot melt adhesive for the filter and the preparation method of the polyolefin hot melt adhesive for the filter comprise catalytic polymers, olefin copolymers, petroleum wax, conditioning agents, plasticizers and auxiliary agents. The stable time of the hot melt adhesive under the high-temperature condition can be prolonged, the situation that hot melt is heated and decomposed is reduced, it is guaranteed that the hot melt adhesive has sufficient viscosity, meanwhile, toxic and harmful gas can be prevented from being emitted when the hot melt adhesive is heated, and harm of the hot melt adhesive to the environment is avoided. 本发明公开了一种滤清器用聚烯烃热熔胶及其制备方法，属于滤清器用热熔胶技术领域，一种滤清器用聚烯烃热熔胶及其制备方法，热熔胶的组分包括：催化聚合物、烯烃共聚物、石油蜡、调节剂、增塑剂和辅助剂。它可以提高热熔胶在高温条件下的稳定时间，降低了热熔热受热分解的情况，保证了热熔胶具有充足的黏性，同时，可避免热熔胶在受热时散发有毒有害的气体，避免热熔胶对环境造成
