Moreover, the industrial glue contains a plurality of components harmful to the body, and the sports pad is a skin-close article and is a harmful molecule which is not environment-friendly.
First embodiment
Referring to fig. 1, the present embodiment provides a two-color layer adhesive-free sports mat 1, where the two-color layer adhesive-free sports mat 1 includes a first thermoplastic elastic material 2 and a second thermoplastic elastic material 3, where the second thermoplastic elastic material 3 is connected to one side of the first thermoplastic elastic material 2, the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 have different colors, and the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 are pressed together by a vulcanizing machine.
Specifically, the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 are vertically arranged and placed in a foaming mold of a vulcanizing machine; and finally, pressing the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 into a whole by using a flat vulcanizing machine with high tonnage (2500T) pressure to form the double-color layer adhesive-free sports mat 1, wherein the hot-pressing composite molding of the two sheets can be realized by adopting a vulcanizing machine pressing process, the structure of the double-color layer adhesive-free sports mat 1 is kept, and the connecting surface of the double-color layer adhesive-free sports mat 1 is firm and is not easy to fall off. Thus, the double-color layer non-adhesive sports mat 1 has perfect appearance of the double-color layer, and physical properties of tear resistance, high elasticity and slip resistance.
Moreover, the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 are pressed into a whole by a vulcanizing machine, and industrial glue is not adopted between the layer structures, so that the thermoplastic elastomer is harmless to human bodies.
The first thermoplastic elastic material 2 is made of a thermoplastic elastic material, and specifically, the first thermoplastic elastic material 2 may be made of TPE or a raw material mainly containing TPE. In the present embodiment, the first thermoplastic elastomer material 2 includes the following substances in parts by mass: TPE 40-50%, SEBS (fully named as Styrene Ethylene butadiene block copolymer), 1-5% of foaming agent, 1-4% of crosslinking agent, 1-3% of ammonia remover, 1-4% of zinc stearate, 2-3% of toner and 10-15% of calcium carbonate. Thus, the thermoplastic elastic material has high flexibility, high mechanical property, excellent damping performance and compression deformation resistance, so that the double-color layer adhesive-free sports mat 1 has the physical characteristics of tearing resistance, high elasticity and skid resistance.
The second thermoplastic elastomer material 3 is made of a thermoplastic elastomer material, and specifically, the second thermoplastic elastomer material 3 may be made of TPE or a raw material mainly containing TPE. In the present embodiment, the second thermoplastic elastomer material 3 includes the following substances in parts by mass: TPE 40-50%, SEBS 20%, foaming agent 1-5%, cross-linking agent 1-4%, ammonia remover 1-3%, zinc stearate 1-4%, toner 2-3%, and calcium carbonate 10-15%. Thus, the thermoplastic elastic material has high flexibility, high mechanical property, excellent damping performance and compression deformation resistance, so that the double-color layer adhesive-free sports mat 1 has the physical characteristics of tearing resistance, high elasticity and skid resistance.
Wherein, the colors of the TPEs used for the first thermoplastic elastic material 2 and the second thermoplastic elastic material 3 are different. The TPE is a thermoplastic elastomer material, has the characteristics of high strength, high resilience and injection molding processing, and has wide application range, environmental protection, no toxicity, safety and excellent colorability. The TPE comprises at least one of styrene materials, olefin materials, diene materials, vinyl chloride materials and polyurethane materials.
Among the raw materials of the first thermoplastic elastic material 2 and the second thermoplastic elastic material 3, the SEBS material can increase the elasticity of the two-color layer adhesive-free sports mat 1. The ammonia remover in the raw material can react with the ammonia in the foaming agent, so that the ammonia does not exist, the odor of the ammonia emitted by the raw material is avoided, and the product grade is improved.

Moreover, the glue-free hot-pressing composite process is adopted, so that two sheets made of different materials can be subjected to hot-pressing composite molding, the structure of the double-color-layer glue-free motion pad 1 is kept, and the connecting surface of the double-color-layer glue-free motion pad 1 is firm and is not easy to fall off.
The preparation method of the double-color layer adhesive-free sports mat 1 provided by the embodiment has the beneficial effects that:
1. the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 are pressed into a whole by a vulcanizing machine, and industrial glue is not adopted between layer structures, so that the material is harmless to human bodies;
2. the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 have different colors and better appearance;
3. the second thermoplastic elastic material 3 and the first thermoplastic elastic material 2 have high flexibility, high mechanical property, excellent damping performance and compression deformation resistance, and have physical characteristics of tear resistance, high elasticity and skid resistance which are not possessed by a common cushion after being pressed by a vulcanizing machine.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
