Wind navigation room temperature vacuum seal rubber belt and producing method thereof

Abstract

The invention discloses an air navigation room temperature vacuum sealing adhesive tape and a manufacturing method thereof. The method comprises the steps: fillings, a vulcanizing agent, an activator, an accelerant and a tackifying resin are added into a butyl rubber; the fillings comprise light-weight calcium carbonate and heavy-weight calcium carbonate; the vulcanizing agent is 201 brominated methylol tert-octyl phenolic resin: the activator is halide and zinc oxide; and the accelerant is TMTD thiuram; and the tackifying resin is polyisobutylene resin. The sealing adhesive tape has the advantages that: the tape is applicable to heat-free curing in the application and joint production of vacuum bags. Under a vacuum condition and at room temperature, the adhesive tape can seal most of sealing thin films and curing tools and can clean the surface of tools at room temperature. The tape is mainly characterized by high elastic modulus, high tensile strength and high surface adhesive force, is easy for application, has quite high adhesive force to the sealing thin films and the curing tools, can be applied at room temperature, is applicable to most of composite materials and thin-film materials and the defoaming by multi-layer composite materials, thus being a low-cost adhesive tape for vacuum bags and being safe and reliable.

Description

technical field [0001] The present invention relates to a kind of vacuum sealing tape for air navigation at room temperature and its production method. The vacuum sealing tape is suitable for vacuum bag application and composite production without heat curing. The tape can seal most sealing films and curing tools under room temperature and vacuum conditions. , the tool surface can be cleaned at room temperature. Background technique [0002] The existing vacuum sealing tapes have poor adhesion to sealing films and curing tools, need to be heated during use, cannot be used at room temperature, have small application range, and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a kind of Fenghang room temperature vacuum sealing tape and its production method to solve the problems of poor adhesion in the prior art, need to be heated during use, cannot be used at room temperature, small in scope of application, and high in cost . ...
