Description
Technical field
The present invention relates to inner tube of a tyre field, is exactly a kind of cracking resistance bicycle inner tube material.
Background technology
The inner tube of a tyre is commonly called as inner tire.Refer to for keeping inner pressure of tire, annular flexible pipe with tyre valve.Inflating valve is in order to inflate and to make air keep certain pressure in the inner tube of a tyre.The inner tube of a tyre should have good resistance to air loss, thermotolerance, elasticity, ageing resistance and less tension set.General isoprene-isobutylene rubber manufactures.
Isoprene-isobutylene rubber is elastomeric one, is synthesized by iso-butylene and a small amount of isoprene.Generally be used in and make inside doughnut and auto sound articles for use.Present isoprene-isobutylene rubber replaces pitch so that the name of environmental protection is comprehensively universal.
The self-closing better performances of butyl glue inner tube of a tyre colloid, has high-air-tightness.Air pressure is at more than 8MPA after the loading for the inner tube of a tyre, and high-air-tightness carcass reduces gas nature seepage, in use inflates frequency and reduces, also more fuel-economizing under steam than the natural gum inner tube of a tyre.Butyl glue inner tube of a tyre high temperature tolerance is more superior than the natural gum inner tube of a tyre, and automobile is when running up for a long time, and tyre cavity temperature is very high, makes the quick self-vulcanizing of interior tire rubber, affects work-ing life. and butyl glue inner tube of a tyre is more ageing-resistant, and duration of service is longer.
Current China isoprene-isobutylene rubber output is extremely low, and supply falls short of demand, existing butyl reclaimed rubber and other natural rubber inner tube of a tyre material properties not good, be badly in need of finding and a kind ofly reduce the novel material for the inner tube of a tyre determining base rubber consumption.
