Polyolefin box sealing glue and preparation method thereof

The invention discloses polyolefin box sealing glue and a preparation method thereof. The polyolefin box sealing glue is prepared from the following raw materials in percentage by weight: 30 to 50 percent of polyolefin plastic bodies, 15 to 25 percent of wax, 10 to 20 percent of petroleum resin, 20 to 30 percent of tackifying resin and 0 to 1.0 percent of antioxidants. The preparation method of the polyolefin box sealing glue concretely comprises the following steps that 1, a stirring container is heated; wax is fed into a stirring container; stirring is started; 2, the polyolefin plastic bodies, partial petroleum resin and partial tackifying resin are added into the stirring container to be stirred; 3, vacuum pumping is performed; 4, the rest petroleum resin and the rest tackifying resin are fed for heating; 5, the materials in the stirring container are subjected to temperature reduction and are discharged; 6, all basic indexes of the product are detected. The polyolefin box sealing glue and the preparation method of the polyolefin box sealing glue provided by the invention have the advantages that the polyolefin box sealing glue has good thermal stability effect and strong thermal viscous force; the curing time is extremely short; the requirements of a fast production line can be met.
