| Abstract: |
| The study aimed to develop a kind of camouflage rubber-plastic composite adhesive plaster with high barrier, heat sealing and excellent resistance to weather. On the basis of comparing with various envelope materials, the layer structure was used and the butyl rubber was used as the barrier layer and polyester fiber as the base material and polyurethane coat as the heat seal layer, then the plaster was made by rubber tape coating process. The problem of difficult adhesion of cover-butyl rubber with skeleton-polyester was solved by pretreating the polyurethane coated fabric. After coating, the plaster was treated with composition and vulcanization during 72 hours of storage and its moisture permeability was 2.19 g/(m2·24 h). The treatment of plaster integrated the existing resources and proceeded with key links of envelope composite material designs such as material performance design, structure design and selection of function materials, which can overcome disadvantages of inconvenience in site construction and poor manufacturability of envelops made by traditional processing of rubber tapes when used for field seal-up of large equipment and this plaster can meet the need of long-term field seal-up of large equipment. |
