Definitions

  • the invention relates to a layered material of a ball for reflective sports, a preparation method of the layered material, and a ball for reflective sports.
  • Ball games have always been one of people's favorite sports. When playing ball games, good lighting is one of the necessary conditions. However, in outdoor sports venues, many places are obviously inadequately illuminated, which makes it difficult to see the sports balls. Therefore, this greatly limits the playing activities at night.
  • the present invention provides, on the one hand, a layered material for reflective sports balls, which is characterized in that the layered material includes a substrate layer, a reflective material layer and a layer of silica particles. Wherein the substrate layer and the silica gel particle layer are respectively adjacent to both sides of the reflective material layer, and the silica gel particle layer does not completely cover the reflective material layer.
  • the present invention provides a method for preparing a layered material for reflective sports balls.
  • the method includes the following steps:
  • the invention also provides the application of the layered material for the reflective sports ball in the reflective sports ball.
  • the present invention also provides a reflective sports ball, which is characterized in that the reflective sports ball includes a surface layer of the sphere, and the surface layer is made of the layered material for the reflective sports ball provided by the present invention.
  • the sports ball made of the layered material for the reflective sports ball provided by the present invention has a very good hand feel, can be easily grasped, and is not easy to slip off, which enables the reflective sports ball to be used properly ; Otherwise, the reflective sports ball is too smooth, difficult to be grasped, and inconvenient to be used.
  • the reflective sports ball provided by the present invention has a good reflective effect, which can fully meet the requirements of ball sports under insufficient light; and has good elasticity, and its rebound height fully meets the requirements of the national standard; and the reflective material layer is not easy to be worn away. Therefore, it is prevented that the reflective material layer is worn and loses the reflective effect, thus greatly increasing the convenience and service life of the reflective sports ball.
  • the reflective basketball provided by the present invention can meet the requirements of the game and can be used as a game ball.
  • the silica gel layer and the reflective material layer are tightly combined, are not easy to fall off, and can well control the weight of the layered material occupied by the silica gel, thereby controlling the elasticity of the ball.
  • Fig. 1 is a schematic diagram of the layered material of the reflective sports ball provided by the present invention.
  • the layered material used for the reflective sports ball includes a composite skin substrate layer 1, a reflective glass microbead layer 2, and a silica gel particle layer 3.
  • FIG 2 is a schematic diagram of a reflective basketball provided by the present invention. As shown in Figure 2, the reflective glass microbead layer 2, the silica gel particle layer 3.
  • the invention provides a layered material for reflective sports balls, characterized in that the layered material includes a substrate layer, a reflective material layer and a silica gel particle layer; wherein the substrate layer and the silica gel particle layer They are respectively adjacent to both sides of the reflective material layer, and the silica gel particle layer does not completely cover the reflective material layer.
  • the base material layer may be different according to different sports balls.
  • the base material layer is made of a surface layer material forming the type of sports balls involved.
  • the base layer is made of the material that forms the surface layer of these types of balls.
  • the substrate layer can be made of the surface layer material forming the basketball, preferably made of rubber, superfine fiber, PU, PVC, composite leather or real leather; more preferably made of composite leather, superfine fiber Or made of PU.
  • the silica gel particles in the silica gel particle layer are uniformly distributed.
  • the surface particle density of the silica gel particle distribution of the silica gel particle layer is per square 20-50 silica gel particles per centimeter of the reflective material layer, preferably 30-40 silica gel particles per square centimeter of the reflective material layer.
  • the shape of the silica gel particles of the silica gel particle layer is not particularly limited.
  • the shape of the silica gel particles of the silica gel particle layer is a cylinder, a ring cylinder, a triangular prism, a truncated cone, Tetrahedron, pentahedron or hexahedron; for the convenience of preparation, it is preferably a cylinder, a circular cylinder, a triangular prism, a truncated cone, a regular tetrahedron, a regular pentahedron or a regular hexahedron; in order to facilitate the preparation and strengthening of the silica gel particle layer
  • the silica gel particles of the silica gel particle layer are preferably cylinders, ring cylinders, or truncated cones.
