embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
Below embodiments of the invention:
Be used for preparing synthetic rubber (NR-SBR-BR) matrix material comprising spider silk of doughnut, it is characterized in that, spider silk is added with in synthetic rubber NR-SBR-BR matrix material, described spider silk composition comprises glycine (NH2-CH2-COOH), L-Ala (NH2-CH [CH3]-COOH), Serine (NH2-CH [CH2OH]-COOH) and amino acid monomer Harmonic Protein Molecular Chains, and proportioning is 1:1:1:1.
In the present invention, the fracture rate of stretching of described spider silk is 140%.
In the present invention, the base diameter of described spider silk is 0.5 ~ 0.7 μm.
In the present invention, the length of described spider silk is 15 μm.
As shown in Figure 1, utilize the doughnut that the NR-SBR-BR matrix material comprising spider silk of the present invention is made, the style of described doughnut can be radial 100, the feature of this tire is the direction consistent with the meridian section of tire (namely crown angle is zero degree) of plies cords arrangement, due to such arrangement of cord, the intensity of Supreme Being's line can be fully used, and the curtain cloth layer of radial generally about can reduce 40-50% than common oblique line tire.Radial is compared with common oblique line tire, and have elasticity large, wear resistance is good, and Using Life of Tyre can be made to improve 30-50%, and rolling resistance is little, can reduce automobile fuel consumption about 8%, and adhesion property is good, and shock-absorbing capacity is good, and supporting capacity is large, not easily the advantage such as puncture.
The style of the doughnut utilizing the NR-SBR-BR matrix material comprising spider silk to make in the present invention also can be tubeless tyre, tubeless tyre and general tire difference are do not have the inner tube of a tyre, air is directly pressed in cover tire, has therefore needed good sealing between tire and wheel rim.And although tubeless tyre is similar to tubed tyre in appearance with in structure, but unlike tubeless tyre inwall addition of the rubber sealant being used for sealing gas specially of thick layer about 2-3mm, it adheres to by the method for sulfuration, when after puncture of tire, puncture thing is wrapped tightly because itself is in compressed state, therefore can be air tight for a long time, even if extracted by puncture thing, also can temporarily keep tire internal gas pressure; Tubeless tyre tyre bead has the ring groove that some roads are concentric, under the effect of tire internal gas pressure, groove line reliably can make tyre bead be pressed on the edge of rim and ensure sealing.The wheel rim installing tubeless tyre is gastight, and it has the bottom of inclination and even enamelled coating, and valve is outspoken by being fixed on wheel rim, pads the rubber gasket sealed therebetween.It is good that tubeless tyre has resistance to air loss, good heat dissipation, and structure is simple, the advantages such as quality is light.
