Please see Figure 1 This invention provides a Christmas tree ornament with luminous and photoluminescent effects and an injection molding process, the process comprising the following steps: Step 101: Preparation of fluorescent paste: Mix 40 to 60 parts by weight of fluorescent powder, 4 to 8 parts by weight of silica micro powder, 5 to 10 parts by weight of polytetrafluoroethylene resin, 5 to 10 parts by weight of polycarbonate and 20 to 40 parts by weight of ethyl acetate evenly to obtain fluorescent paste.

[0024] Specifically, a fluorescent paste is prepared by uniformly mixing 40 to 60 parts by weight of phosphor, 4 to 8 parts by weight of silica micropowder, 5 to 10 parts by weight of polytetrafluoroethylene resin, 5 to 10 parts by weight of polycarbonate, and 20 to 40 parts by weight of ethyl acetate using a high-speed mixer. Further, the high-speed mixer rotates at 400 rpm for 10 minutes.

[0025] Step 102: Mixing transparent plastic granules: Mix 20 to 40 parts by weight of transparent ABS granules, 10 to 30 parts by weight of transparent PP granules, 10 to 20 parts by weight of transparent PET, and 15 to 25 parts by weight of transparent PVC until homogeneous to obtain transparent mixed plastic raw materials.

[0026] Specifically, a high-speed mixer is used to mix 20 to 40 parts by weight of transparent ABS granules, 10 to 30 parts by weight of transparent PP granules, 10 to 20 parts by weight of transparent PET, and 15 to 25 parts by weight of transparent PVC until homogeneous, thus obtaining a transparent mixed plastic raw material. Furthermore, the high-speed mixer rotates at 300 revolutions per minute, and the mixing time is 8 minutes.

[0027] Step 103: Preheating of transparent plastic granules: Add 40 to 60 parts by weight of transparent mixed plastic raw material to the injection molding machine for preheating treatment to obtain preheated plastic raw material.

[0028] Specifically, 40 to 60 parts by weight of a transparent mixed plastic raw material are added to an injection molding machine for preheating treatment to obtain a preheated plastic raw material. The preheating temperature is 180 to 240 degrees Celsius.

[0029] Step 104: Raw material mixing and stirring step: Mix 40 to 60 parts by weight of preheated plastic raw material, 30 to 50 parts by weight of fluorescent paste, 0.1 to 0.2 parts by weight of stabilizer, 0.2 to 0.4 parts by weight of toughening agent, 0.15 to 0.3 parts by weight of UV stabilizer, 0.1 to 0.2 parts by weight of wetting agent, and 0.02 to 0.04 parts by weight of antioxidant in an injection molding machine and heat to a liquid state to obtain liquid fused injection molding raw material.

[0030] The antioxidant is a phenolic antioxidant. The UV stabilizer is resorcinol monobenzoate. The toughening agent is EVA plastic granules. The stabilizer is barium stearate. The wetting agent is polyethylene wax. Specifically, 40 to 60 parts by weight of preheated plastic raw material, 30 to 50 parts by weight of fluorescent paste, 0.1 to 0.2 parts by weight of stabilizer, 0.2 to 0.4 parts by weight of toughening agent, 0.15 to 0.3 parts by weight of UV stabilizer, 0.05 to 0.1 parts by weight of UV stabilizer, 0.1 to 0.2 parts by weight of wetting agent, and 0.02 to 0.04 parts by weight of antioxidant are mixed and stirred evenly in an injection molding machine and heated to a liquid state to obtain a liquid fused injection molding raw material. The heating temperature is 280 to 300 degrees Celsius.

[0031] Step 105: Injection Molding Step: Inject the liquid fused injection molding material into the pendant mold.

[0032] Specifically, the injection molding machine injects the liquid fused injection molding material into the pendant mold.

[0033] Step 106: Cooling and Demolding Step: After cooling, demold to obtain the Christmas tree ornament.

[0034] Specifically, cold water is used for cooling. After cooling, the Christmas tree ornaments are demolded.

[0035] The aforementioned Christmas tree ornaments with luminescent and phosphorescent effects, along with their injection molding process, are concise, sophisticated, and easy to control. Each step requires meticulous attention, resulting in Christmas tree ornaments with excellent transparency, high phosphorescence efficiency, short processing time, long-lasting luminescence, and good gloss. The polytetrafluoroethylene resin in the fluorescent paste exhibits excellent high-temperature resistance, which enhances the high-temperature performance of the luminescent and phosphorescent Christmas tree ornaments.

[0036] To enhance the glitter effect of luminescent and phosphorescent Christmas tree ornaments, ensuring their excellent decorative performance even during the day, 4 to 6 parts by weight of glitter particles are added during the raw material mixing step 104. These glitter particles are made from a glitter material comprising the following components in parts by weight: 10 to 20 parts epoxy resin, 20 to 40 parts silicone resin, 2 to 4 parts ethylene glycol monobutyl ether, 2 to 4 parts triglycidyl isocyanurate, 20 to 30 parts metallic composite glitter powder, and 15 to 30 parts composite filler particles. This glitter material, composed of the listed components, enhances the glitter effect of luminescent and phosphorescent Christmas tree ornaments, ensuring their excellent decorative performance even during the day.

[0037] To enhance the glitter effect of the metallic composite glitter powder, the metallic composite glitter powder comprises the following components in parts by weight: 20 to 40 parts copper powder, 5 to 10 parts cuprous oxide powder, 10 to 20 parts zinc oxide powder, 20 to 30 parts titanium dioxide powder, 10 to 20 parts mica powder, and 10 to 20 parts aluminum powder. The metallic composite glitter powder composed of the above components can enhance the glitter effect, allowing the glitter particles to emit brilliant colors, thus increasing the decorative appeal of Christmas tree ornaments with luminous and phosphorescent effects during the day.

[0038] To enhance the heat resistance and structural stability of the flash particles, the composite filler particles are sintered from composite fillers. The composite filler comprises the following components in parts by weight: 24 to 44 parts laterite, 10 to 30 parts bauxite, 8 to 36 parts bentonite, 2 to 4 parts glyceryl monostearate, 1 to 2 parts sodium aluminosilicate, 1 to 3 parts polyvinyl alcohol, and 5 to 10 parts paraffin oil.

[0039] The preparation method of composite filler particles is as follows: Step 201: Mix the red clay, bauxite, and bentonite according to the above components, stir evenly, and calcine at 800°C to 1000°C for 2 to 3 hours. After cooling, a solid material is obtained.

[0040] Step 202: Mix and stir the above-mentioned components (glyceryl monostearate, sodium aluminosilicate, polyvinyl alcohol, and paraffin oil) until homogeneous, and heat to 80 to 100 degrees Celsius to obtain a liquid.

[0041] Step 203: Add the heated liquid to the solid material, mix and stir evenly, and then granulate to obtain composite filler particles.

[0042] The composite filler composed of the above components can increase the heat resistance and structural stability of the flash particles.

[0043] This invention also provides a Christmas tree ornament with luminous and phosphorescent effects, prepared by the method in any of the above embodiments. The Christmas tree ornament with luminous and phosphorescent effects has good transparency, high phosphorescence efficiency, short phosphorescence time, long-lasting luminescence after phosphorescence, and good luminescence gloss. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
