AI Technical Summary

Problems solved by technology

Because the total weight of the remote control model car is extremely light, the heat accumulation that ordinary hot-melt tires can generate during high-speed driving is limited, and it cannot reach the heat required by the softening point temperature of the tread rubber, resulting in the The surface cannot produce hot melt state

Embodiment Construction

[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] There are two main ways for tires to accumulate heat during driving, which are:

[0017] 1. The heat generated by the tire surface and the ground;

[0018] Under the premise that the friction coefficient between the total weight of the vehicle body and the road surface is fixed, the increase of the friction force needs to increase the hysteresis and adhesion of the rubber.

[0019] 2. Heat generated between rubber compounds inside the tire;

[0020] The slip and roll angle of the tire when cornering will cause shear friction between the tread rubber to generate heat, and the difference in frictional heat generation between the rubber materials is positively correlated with the structure of carbon black.

[0021] Therefore, there are three main ways to reduce the softening point temperature of the hot-melt trea...

Abstract

The invention provides a remote control model car full-hot-melt tire tread rubber formula, wherein the components comprise, by weight, 100 parts by weight of raw rubber, 10-150 parts by weight of carbon black, 90-110 parts by weight of aromatic hydrocarbon oil, 40-60 parts by weight of a resin, 1-5 parts by weight of stearic acid, 3-20 parts by weight of zinc oxide, 1-5 parts by weight of an anti-ozone anti-aging agent, 1-5 parts by weight of protective wax, 0.1-3 parts by weight of sulfur and 0.1-3 parts by weight of an accelerant. By reducing the sulfur content, reducing the rubber content of the rubber material and properly proportioning the aromatic hydrocarbon oil and the petroleum resin, the hot melting effect of the remote control model car tire is improved. The invention further provides a tire produced according to the formula, and a remote control model car provided with the tire.

Description

technical field [0001] The invention relates to the technical field of rubber tires and their preparation and application, in particular to a full-heat-melt tire tread rubber composition for remote control model car racing. Background technique [0002] The hot-melt tires assembled on general or heavy-duty motorcycles today can cause the tires to be hot-melted during high-speed driving due to the total weight of the car body (positive force) and the force generated by the tire and the road in the opposite direction (shearing force) Force) formed under the synergistic effect. When both the positive force and the shear force of the tire are applied to the contact surface (friction coefficient) at the same time, a friction force will be formed, and the friction force generated continuously during the high-speed driving of the vehicle will do work (form energy) on the tire, and the friction force will The energy generated by the tire will be transferred (high to low), part of t...
