Abstract

The invention discloses a durable industrial adhesive tape, which comprises the following components by weight ratio: 7-14 parts of polyurethane, 3-5 parts of 3-hydroxyl-propionitrile, 2-3 parts of calcium stearate, 6-9 parts of polypropylene, 5-8 parts of polypropylene glycol 2000, 5-6 parts of ethylene oxide and 3-4 parts of o-phenylphenol. A preparation method of the industrial adhesive tape comprises the following steps: 1)turning on a mixing roll, preheating the mixing roll, respectively weighting polyurethane, 3-hydroxyl-propionitrile and calcium stearate, mixing under high temperature at 150-170 DEG C; 2)adding polypropylene, ethylene oxide and o-phenylphenol in the mixing roll for mixing again; 3)adding polypropylene glycol 2000 in the mixing roll for mixing again; and 4)after mixing is completed, compacting and molding the adhesive tape by using a mole to obtain the durable industrial adhesive tape.

Description

technical field [0001] The invention belongs to the field of adhesive tapes, and relates to an adhesive tape and a preparation method thereof, in particular to a durable industrial adhesive tape and a preparation method thereof. Background technique [0002] Industrial tapes play an important role in the manufacturing industry and industrial operation of products. For example, in electrical engineering and logistics engineering, industrial adhesive tape has many uses. Industrial glue is used in the assembly of equipment and components in these fields and plays an important role. [0003] There are many types of industrial tapes, such as sealing tape, warning tape, cloth tape, aluminum foil tape, etc. Different industrial tapes especially correspond to the scope of use. The durability of conventional industrial tapes is generally poor, and it is necessary to continue to improve the durability of its use. The durability is poor. After a long time of use, industrial tap...
