Embodiment Construction

[0023] The following examples further illustrate the technical solutions of the present invention.

[0024] The invention provides a polyolefin box sealing glue and a preparation method thereof. The polyolefin box sealing glue contains the following raw materials in weight percentage: 30-50% of polyolefin plastic body, 15-25% of wax, 10-25% of petroleum resin 20%, tackifying resin 20-30%, and antioxidant 0-1.0%.

[0025] Among them, the glass transition temperature of the polyolefin plastic body is -60°C, the wax is polyethylene wax, the petroleum resin is a hydrogenated C5 petroleum resin with a softening point of 100°C, and the tackifying resin is a hydrogenated C5 petroleum resin with a softening point of 115°C. The antioxidant is a composite antioxidant containing hindered phenol and phosphite.

[0026] Among them, Bareco SX 100 is used for wax, Eastotal C 100W is used for petroleum resin, Eastotal C 115W is used for tackifying resin, and Irganox B 225 is used for antioxi...

Abstract

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.

Description

technical field [0001] The invention relates to a case sealing glue, in particular to a polyolefin case sealing glue and a preparation method thereof. Background technique [0002] Polyolefin sealing glue is a kind of hot melt adhesive used for bonding cardboard boxes and cartons. At present, polyolefin sealing adhesives mainly include hot melt adhesives based on polyethylene, polypropylene and their respective copolymers. The sealing adhesive made of polyolefin base material has the advantages of strong bonding performance and strength after cooling. [0003] At present, the polyolefin sealing adhesives on the market meet the requirements in terms of bonding strength, but the thermal stability is not very good, and there will be low-temperature or high-temperature glue opening phenomenon. Contents of the invention [0004] The object of the present invention is to provide a kind of polyolefin sealing glue and preparation method thereof, this polyolefin sealing glue can ...
