High and low temperature resistant thin splash-proof tape and preparation method thereof

Abstract

The invention discloses a high and low temperature resistant thin splash-proof tape and a preparation method thereof. The splash-proof tape comprises a base material layer composed of aluminum foil and glass fiber cloth, a silicone pressure-sensitive adhesive layer and a release film layer. Its preparation method is to first compound aluminum foil and glass fiber cloth as a base material, then coat silicone pressure-sensitive adhesive, dry and solidify, and stick release film. The silicone pressure-sensitive adhesive composition is: 100 parts of polydimethylsiloxane containing vinyl, 80-150 parts of vinyl MQ resin, 0.2-0.5 parts of silane coupling agent, 0.02-0.2 parts of polymethyl Hydrogen siloxane, 0.01~0.03 part platinum chelate, 0.003~0.006 part acetylenic alcohol. The anti-splash tape prepared by adopting the preparation process of the present invention can be widely used in joints, valves and the like of high-temperature and high-pressure pipelines to prevent fuel oil from leaking and splashing. The anti-splash belt can withstand high pressure below 1.5Mpa without multi-layer wrapping and winding, and can be used for a long time in the range of -50~150°C.

Description

technical field [0001] The invention relates to a wrapping covering for pipe joints and a preparation method thereof, in particular to a splash-proof strip and a preparation method thereof, which are applied in the technical field of production and manufacturing of auxiliary coverings for fluid transport pipeline joint seals. Background technique [0002] The International Maritime Convention (IMO) clearly pointed out in the SOLAS II-2 / 15.2.11 treaty that for new ships with an output power exceeding 375KW, the surface of the pipe valve in the engine room must have protective measures to prevent fires caused by high-pressure fuel spray. In order to prevent flammable oil from flying, it is required to cover the joints of the pipe fittings with heat-resistant, pressure-resistant and air-tight materials. At the same time, ship transportation and offshore oil platform construction sometimes cannot avoid cold areas, and the coverings must also have the performance of low temperatu...

AI Technical Summary

Problems solved by technology

Although the compressive tensile strength of the metal fiber mesh is also good, but the flexibility of the metal mesh cloth is poor, and the splash-proof belt made is relatively hard. In uneven areas such as valves and elbows, the fit with the covered area is poor, and leaks are prone to occur. gap, and the manufacturing cost of the metal mesh is large
