Abstract
The invention discloses an expansion tank leather film with characteristics of good air tightness and long usage life. The expansion tank leather film comprises the following raw materials by mass: 45-60% of butadiene-acrylonitrile rubber, 20-25% of carbon black, 10-15% of plasticizer, 2-5% of age proof agent, 1-3% of vulcanizing agent and balance of auxiliary agent. The expansion tank leather film is suitable for a wall hanging furnace water heater.
Description
Technical field
The present invention relates to a kind of wall-hung boiler water-heater, relate in particular to one and be suitable for wall-hung boiler water-heater expansion tank epithelium.
Background technology
Expansion tank is one of key part in wall-hung boiler water-heater, and epithelium is the major parts in expansion tank, and the quality of its performance directly affects the normal operation of wall-hung boiler water-heater.The frequent variations that on the one hand will bear pressure due to epithelium, and the highest water temperature reaches 80 DEG C, in addition, because waterworks adopts ordinary tap water, water quality composition is comparatively complicated, thereby higher to the material requirements of epithelium, and usual production is in order to reduce costs, adopt General Purpose Rubber to make, and the high-temperature resistant of this material only have 80 DEG C, thereby easily produce agingly, affect work-ing life; And air-tightness is poor, make because epithelium adopts elastomeric material, elastomeric material has very important performance index, and that is exactly air-tightness, as bad in air-tightness, nitrogen just can directly be seeped in opposite side water by epithelium, because the nitrogen amount of epithelium one side is relevant with design pressure, as nitrogen amount reduces, cause pressure to reduce, pressure also thereupon can not be constant, make the time shorten of constant pressure, thereby the system that affects normally moved.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of resistance to air loss is good, the expansion tank epithelium of long service life.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Its raw material of the present invention and mass percent are: butadiene-acrylonitrile rubber 45～60%, carbon black 20～25%, softening agent 10～15%, antiaging agent 2～5%, vulcanizing agent 1～3%, other auxiliary agents are surplus.
As preferably, described butadiene-acrylonitrile rubber 45%, carbon black 25%, softening agent 15%, antiaging agent 5%, vulcanizing agent 3%, other auxiliary agents are 7%.
As preferably, described butadiene-acrylonitrile rubber 55%, carbon black 23%, softening agent 13%, antiaging agent 4%, vulcanizing agent 2%, other auxiliary agents are 3%.
As preferably, described butadiene-acrylonitrile rubber 60%, carbon black 20%, softening agent 10%, antiaging agent 2%, vulcanizing agent 1%, other auxiliary agents are 7%.
Because the present invention adopts butyronitrile synthetic rubber as material, thereby make heatproof approach 120 DEG C, there is the characteristics such as resistance to air loss is good, anti-aging, wear-resisting, oil resistant is dirty, effectively extended work-ing life.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
The preferred embodiment of the present invention one: raw material and mass percent are: butadiene-acrylonitrile rubber 45%, carbon black 25%, softening agent 15%, antiaging agent 5%, vulcanizing agent 3%, other auxiliary agents are 7%.
Preferred embodiment two: raw material and mass percent are: described butadiene-acrylonitrile rubber 55%, carbon black 23%, softening agent 13%, antiaging agent 4%, vulcanizing agent 2%, other auxiliary agents are 3%.
Preferred embodiment three: raw material and mass percent are: butadiene-acrylonitrile rubber 60%, carbon black 20%, softening agent 10%, antiaging agent 2%, vulcanizing agent 1%, other auxiliary agents are 7%.
The heat resistance of the present invention that adopts aforesaid combination raw material to make can approach 120 DEG C, has the characteristics such as resistance to air loss is good, anti-aging, wear-resisting, oil resistant is dirty simultaneously.
