Therefore, It should be understood that various equivalents and modifications may be present.

The present invention relates to an adhesive pad for preventing slippage of tire and a method of manufacturing the same, which comprises a vulcanizing step (S1) for mixing and heating sulfur mixed with rubber, which is a main component of the pad, so as to easily cope with irregular road surface conditions and winter season temperature changes; A wood powder addition step (S2) of adding hardwood wood powder to the rubber mixed with sulfur by a vulcanization step (S1) so as to improve frictional force with the road surface; A mixture kneading step (S3) of kneading the mixture to which hardwood wood is added in the vulcanized rubber by using heat and a machine so as to maintain constant hardness; A mixture extruding step (S4) of injecting the kneaded mixture into a mold and extruding the kneaded mixture to a predetermined thickness; A pattern forming step (S5) of forming a pattern on the ground portion so that the frictional force with the road surface can be doubled by the shape of the surface of the pad; A cutting step (S6) of cutting the patterned molded mixture to a size suitable for attaching to the tire of the vehicle; The present invention relates to an adhesive pad for preventing slippage of a tire and a manufacturing method thereof.

More specifically,

In the vulcanization step (S1), 2 phr of sulfur is added to rubber so as to compensate for the disadvantages of the rubber which is softened in the summer when the road surface temperature is high, and hardened in the winter when the road surface temperature is low. (Semi-flow type) to 300 (full flow type). By heating for a short time, it is possible to improve durability by increasing rubber tension so that it is not easily damaged even on irregular road surface. Processing step.

Semi-cushion flow improves the rubber cushion feeling and adhesion, but reduces the working efficiency and durability as compared with the full flow.

In the step of adding wood powder S2, the hardwood mixed with sulfur is mixed in a ratio of 0.6: 0.4 to a vulcanized rubber mixed with sulfur by a vulcanization step (S1) The particles of the added hardwood wood particles increase the friction with the road surface to improve the stability of the steering and the braking performance of the vehicle. In the vulcanized rubber, softwood wood (softwood) The particles of the wood powder added during driving are easily damaged by the friction with the road surface, so that the effect of increasing the frictional force may be lowered compared to the wood particles of the hardwood.

The mixture kneading step (S3) is a step of heating a mixture of vulcanized rubber and hardwood wood at a temperature of 160 to 180 DEG C to maintain the hardness of SHORE A of 50 to 60, Workability and stability of adhesion and steering can be improved when a pad is attached to a tire of a vehicle.

The mixture extruding step S4 is a step of molding a mixture of the vulcanized rubber processed by the mixture kneading step S3 and woody wood particles to a thickness of 0.6 to 0.8 mm, There is a problem that the stability of the steering and the riding comfort of the vehicle may be deteriorated after two or more pads are not uniformly attached to one tire.

In the pattern forming step S5, the hardwood wood forming the tire non-slip pad is not exposed to the ground surface with the road surface due to the covering of the vulcanized rubber, so that the frictional force is prevented from being lowered. A mixture of vulcanized rubber molded to a constant thickness and woody wood particles is injected into a mold to mold a pattern having a certain shape on the ground surface of the road surface.

In the cutting step S6, a mixture of a pad-shaped vulcanized rubber having a predetermined pattern formed on the ground surface with the road surface and a woody hardwood wood powder can be fitted to the tire of the vehicle by the pattern forming step S5, To 10 cm to 12 cm and a length of 14 cm to 16 cm so as to improve frictional force.

As shown in Table 1 above, braking force, acceleration and hill climbing force are improved compared to normal tires. That is, it is possible to attach the patch to the tire without changing the winter tires in the winter and to travel for more than 300 km.

In one embodiment,

The tire adhering portion 110 is provided with the adhesive guide line 111 when the adhesive pad 100 for preventing slippage of the tire is adhered to the tire 300 of the vehicle. After removing excess moisture and foreign substances adhered to the tire adherend 110, The adhesive can be applied uniformly along the adhesive guiding lines 111 provided on the substrate. At this time, the adhesive to be applied to the adhesive guide line 111 is a cyanoacrylate-based high viscosity chemical adhesive, which can prevent the adhesive agent from escaping to the outside of the tire adhering portion 110 due to the viscosity of the adhesive, The tire non-slip prevention pad 100 can be firmly adhered to the tire 300 of the vehicle by the moisture-curing adhesive capable of improving the adhesion when containing a certain amount of water. The tire non-slip pad 100 may be applied by applying an adhesive to the respective tires 300 at an interval of 4 to 6 cm in an interval of 2 to 4 to form an adhesive layer 200, It is preferable that the rear wheel drive vehicle is attached to the rear wheel.

As shown in Fig. 5, the vulcanized rubber constituting the tire non-slip adhesion pad 100 is subjected to friction with the road surface during an initial running of less than 1 km after attaching the tire anti-slip adhesion pad 100 to the tire 200 of the vehicle. The hardwood wood covered with the vulcanized rubber is exposed to the outside of the furnace surface-contacting portion 120 in which the pattern 121 is formed, whereby the frictional force with the snow surface is increased, The adhesion pad 100 for preventing slippage of the tire may be attached to the tire 200 of the vehicle and may be attached to the tire by a friction pad for anti- 100) are worn out and removed, so that convenience of use can be improved.

As described above, the present invention has been described with reference to particular embodiments, such as specific elements, and specific embodiments and drawings. However, the present invention is not limited to the above-described embodiments, Various modifications and variations may be made thereto by those skilled in the art to which the present invention pertains.
