Abstract

The invention relates to a butyl rubber based pressure-sensitive protective tape and a preparation method thereof. The protective tape is obtained by coating a substrate layer with a pressure-sensitive adhesive. Specifically, the pressure-sensitive adhesive comprises the following components by mass: 30-55 parts of matrix resin, 15-40 parts of tackifying resin, 10-20 parts of a plasticizer, and 5-15 parts of inorganic filler. The protective tape provided by the invention has the advantages of excellent mechanical properties and electrical performance, simple preparation method and low cost, is suitable for industrial production and has good application prospect.

Description

technical field [0001] The invention belongs to the field of automotive electronic circuit protection, in particular to a butyl rubber-based pressure-sensitive protective adhesive tape and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's automobile industry, equipment replacement and repair has become one of the important links. Among them, the waterproof and insulating protection of electronic component joints is particularly important, and it is also the key to the efficient operation of the entire system. Pressure-sensitive tape has become one of the effective solutions to the above problems due to its convenient use, wide application fields and excellent performance. [0003] The bonding mechanism of pressure-sensitive adhesive is to use the unique viscoelasticity of its polymer materials to make the colloid flow viscously under the action of a small force, and form a van der Waals force with the adh...
