Description
Technical field
The invention discloses a kind of all-steel radial tyre steel ring wrapping fabric glue, the invention also discloses a kind of preparation method of all-steel radial tyre steel ring wrapping fabric glue.
Background technology
Usual employing has the film coated wire bead manufacture aerated rubber tyre that fibercord covers glue.This class formation is well-known in tire industry.The composite structure that this class formation is above-mentioned two parts will be quoted herein.
In general, steel ring composite structure comprises the steel wire one being covered glue is wound in circle (cross section is hexagon) and coated steel ring film by certain arrangement, steel ring and rubber form one-piece construction after over cure, thus improve the rigidity of steel ring, the Wheel Rim deformation of reduction and prevent steel ring and the framework material in carcass from occurring directly to contact.
At present, the steel ring wrapping fabric glue film of all-steel radial tyre is that steel ring wrapping fabric glue and fibercord are combined into through rolling press fibercord glue is cut into corresponding size specification again infantees film through clipper.Steel ring needs the cloth-covered opening-guiding twining into rouleau to be wrapped on steel ring when being wound around infantees film, winding process needs infantees film face to have suitable viscosity, viscosity is crossed conference and is caused binding can not draw away between infantees film being unfavorable for that infantees film is led out, and the too low meeting of viscosity makes infantees film can not be wrapped on steel ring; Also need infantees film to have certain tensile strength simultaneously and can ensure that the dimensional change of infantees film stretched rear film when being wound around is less like this, the infantees film sizing material that steel ring is wound around is evenly distributed; Infantees glue film has the mobility of suitable hardness and lower sizing material.When tire can be caused like this to be squeezed in shaping and sulfidation, the infantees sizing material flowing of steel ring edge property at parts of edges and corners excessively causes the sizing material thickness between steel ring corner angle position and carcass to reduce.This belongs to a kind of disadvantageous factor, in tire used process, there will be the fiber of tyre rim corner angle easily and in steel ring wrapping fabric glue produce friction and occur that infantees film is cut off, the framework material of carcass can be caused further also by situation that the friction sawing of steel ring corner angle is blown out.
Anti-form-1,4-polyisoprene (TPI) exists, and less than 60 DEG C there will be crystallization, in plastics state; TPI with other rubber (NR, SBR, BR, IR etc.) and with exceed certain proportion can make blend compounds easily crystallization at normal temperatures equally, in plastics state, but can be then elastomerics after covulcanization.The introducing of trans-isoprene can make steel ring wrapping fabric glue be provided with the characteristic of TPI equally, can solve the problem that steel ring wrapping fabric glue mobility is excessive and film face viscosity is excessive so very well.
