The beneficial effects of the invention are as follows：By improving the glass transition temperature Tg point of sizing material, make sizing material at 50-80 DEG C
Fissipation factorApparent increase, the adherence properties under the racing starting stage and middle and later periods each violent use condition of improving sizing material
Energy；By improving firmness change rate of the sizing material in temperature-rise period, make sizing material under conditions of room temperature is increased to 80 DEG C, hardness by
53-55 ° is dropped rapidly to 38-42 °, improves sizing material and the contact area and adhesion property on ground.
Quantitative analysis is carried out to the advantageous effect of this case below by test data.6 group of formula are selected to make motor respectively
Tire, in addition to the properties of rubber such as hardness, glass transition temperature and fissipation factor detect, in same model, identical place and ring
Under the conditions of border, 30 circle place test runs are carried out respectively, are detected respectively into start of line earth-grasping force and driving process middle and later periods earth-grasping force
Subjective assessment.
As seen from the above table, case study on implementation E fissipation factors are higher, but sizing material viscosity is excessive, can not process；Case study on implementation A and implementation
Case B starting earth-grasping forces are fine, but middle and later periods earth-grasping force is insufficient；Case study on implementation D and the places case study on implementation F trial effect are preferable,
But case study on implementation F glass transition temperatures are higher, the problem of cryogenic conditions storage causes sizing material harder breach, therefore case study on implementation
D is as optimal case.
Meanwhile by the test data of upper table it is found that case study on implementation D provides superior starting grip performance at initial stage of riding,
Decline smaller, excellent in te pins of durability in middle and later periods grip performance, the later stage also can guarantee enough grip performances, it is competing to provide motorcycle
The safety of fast automobile race and handling.
In conclusion the present invention is not limited to above-mentioned specific implementation modes.Those skilled in the art are not departing from the present invention's
Under the premise of spirit and scope, several change or modification can be done.Above-mentioned change or modification each fall within the protection model of this present invention
It encloses.
