The invention relates to the technical field of sporting goods manufacturing, and discloses an
epoxy resin-based environment-friendly
crystal billiard ball which is composed of a ball core and an outer
coating layer, and the preparation steps sequentially comprise
raw material pretreatment, ball core forming, secondary pouring
coating, curing, post-
processing and surface treatment. The
raw material pretreatment comprises base
material system configuration, filler treatment and mixed
slurry preparation, the base
material system takes
epoxy resin as matrix resin and is matched with an amino curing agent, the
mass ratio of the
epoxy resin to the curing agent is 100: (25-30), the filler comprises 2800-3500-mesh
barium sulfate powder, a nanoscale
inorganic filler and high-mesh silica
powder of which the mesh number is greater than or equal to 20000 meshes, and the mixed
slurry is prepared from the following raw materials in parts by weight. The mixed
slurry is divided into ball core slurry and
coating layer slurry which are both stirred and dispersed by a high-speed dispersion
machine, and a segmented heating curing process is adopted for curing. The process parameters are clear and controllable, the method is suitable for large-scale production, the raw materials are easy to obtain, the cost is controllable, and the method has a good market application prospect.
