Abstract

The invention discloses a chloroprene rubber-based pressure sensitive tape, which comprises the following components by weight ratio: 32-39 parts of chloroprene rubber, 17-22 parts of butadiene, 5-9 parts of polyvinyl methyl ether, 2-4 parts of diethylenetriamines, 6-10 parts of acrylonitrile, 4-7 parts of glyoxal and 5-6 parts of hydroxytrimethylsilane. A preparation method of the chloroprene rubber-based pressure sensitive tape comprises the following steps: 1)taking chloroprene rubber and butadiene, uniformly mixing chloroprene rubber and butadiene with stirring to obtain a mixture; 2)adding the mixture obtained in the step 1) in a mixing roll from a feed inlet, adding polyvinyl methyl ether, diethylenetriamines and acrylonitrile for mixing in the mixing roll from the feed inlet; 3)adding glyoxal and hydroxytrimethylsilane in the mixing roll and then mixing; and 4)cutting a chloroprene rubber-based pressure sensitive adhesive to obtain the pressure sensitive tape.

Description

technical field [0001] The invention belongs to the field of pressure-sensitive adhesives, and relates to a pressure-sensitive adhesive tape and a preparation method thereof, in particular to a neoprene-based pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is an adhesive that is sensitive to pressure. When the pressure-sensitive adhesive is pressed by an external force, the pressure-sensitive adhesive will bond with the adherend and is not easy to fall off. Typically, pressure-sensitive adhesive tapes are bonded to related materials, such as films, circuit boards, etc. [0003] There are also many types of pressure-sensitive adhesives, mainly rubber-based pressure-sensitive adhesives and resin-based pressure-sensitive adhesives. Among them, rubber pressure-sensitive adhesives are divided into natural rubber pressure-sensitive adhesives and synthetic rubber pressure-sensitive adhesives. With th...
