100 parts of butyl rubbers (IR),
10～30 parts of semi-reinforcing hydrocarbon blacks,
20～50 parts of tackifying resins,
5.0～8.0 parts in zinc oxide.
The effect of adherent layer is to prevent that the adhesive surface of rubber bound layer is contaminated, protects simultaneously that the materials such as the RX in the rubber bound layer, tackifier do not run off under unused state, has reliably adhesion stress to guarantee it.Adherent layer is made by the paper that applies the organic siliconresin anti-stick coating.When anti-explosion safety inspection uses with well lid rubber strip of paper used for sealing, as long as the security staff throws off the surface that adherent layer can stick on it checking matter with hand.
In order to guarantee that anti-explosion safety inspection is that when opening strip of paper used for sealing break rather than by complete open at well lid by the people with well lid rubber strip of paper used for sealing, need to carry out pre-rupture to the rubber surface layer of strip of paper used for sealing, namely in the position of rubber surface layer over against the rubber bound layer, two groups of parallel arrangements are engraved the pre-breach that decorative pattern forms by discontinuous arc side by side.The effect of pre-breach is the uniformity of breach position when guaranteeing that strip of paper used for sealing is torn by external force.
For information such as safety check cycle of recording tested missile silo, number of times, at anti-explosion safety inspection with information symbols such as the rubber surface layer positive printing alarming sign of well lid rubber strip of paper used for sealing and computer codes.
Beneficial effect:
The present invention makes simply, using method is easy, and the safety check state of guaranteeing missile silo is played effective effect.As example, the present invention also can be used for other need to identify the place of closed state, such as: urban fire-fighting equipment storeroom, urgent Vomitory etc. is located.
