Problems solved by technology

[0004] When the pipeline leaks, there are many methods currently used, such as shutting down for maintenance, replacement or temporary closure for re-welding, or using temporary seals to block and other methods. For various special-shaped pipelines, protruding edges, Valves, ball joints, screws, nuts and other special parts and objects with complex shapes, shutting down for maintenance, replacement or temporary closure for re-welding will easily cause production interruption and bring huge economic losses to the whole plant; and adopt temporary sealing method , the existing sealing measures have limited airtightness, and it is difficult to avoid the secondary occurrence of fluid leakage, which will bring immeasurable losses and damage to production and the environment
Moreover, the existing methods are time-consuming, labor-intensive and labor-intensive, and the construction efficiency is low.

Abstract

The invention discloses an environmentally friendly adhesive tape. The adhesive tape includes a release film, a base material, and a composite adhesive coated between the base material and the releasefilm; and the composite adhesive consist of, by weight, 25-80 parts of diphenyl hexa-polymethylsiloxane modified polyethylene resin, 3-12 parts of aromatic polycarbonate resin, 0.2-3.6 parts of a rubber modified glass fiber, 0.8-5 parts of a filling material, 1.2-3 parts of graphene oxide, 1.2-3.5 parts of a compatilizer, 1-5 parts of a dispersing agent and 0.5-2.1 parts of a flexibilizer. The adhesive tape cannot discharge harmful substances during preparation, and can maintain high viscosity and mechanical strength in a using temperature range of 80-150 DEG C, so that the harmful substancescannot be generated to pollute environments; and the adhesive tape has good flexibility, adhesive force and structural displacement tracing abilities, and is good in sealing effect and convenient inconstruction, so that the adhesive tape has wide market application prospects. A preparation method of the adhesive tape is also disclosed.

Description

Technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an environmentally friendly adhesive tape and a preparation method thereof. Background technique [0002] In the field of thermal energy engineering, the long-term operation of high-temperature pipelines and equipment causes leakage of high-temperature materials in the pipeline equipment, or due to long-term exposure to harsh outdoor environments, the transmission pipeline is prone to dripping and leakage of high-temperature steam. In order to ensure its safe operation and save resources, it is necessary to develop targeted preventive measures or emergency measures. [0003] With the rapid development of electronic products, the performance requirements of double-sided adhesive tapes in some occasions are getting higher and higher, especially the requirements for high temperature resistance. High temperature resistance mainly refers to ensuring that the adherend is not in a high ...
