A. In terms of the formula: In the following aspects:

  1. Selection of plastic: It is best to use powder, and the higher the melting index, the better. Because the higher the melt index of the resin, the more fully the role of the light-emitting material can be exerted.
  1. Selection of luminescent powder: The effect of luminescent powder with a smaller particle size below 300 mesh is the best.
  1. Lubricant selection: For polyester (such as PE, PP) resin, “stearic acid amide” should be selected as the lubricant, and the amount should be 0.2% of the resin amount. ABS, PS, PC, AS, PMMA, and other resins use “stearic acid amide” as the lubricant, and the amount is 0.5% -3% of the resin, generally 1%.
  1. Selection of dispersant: Selecting powdered PE wax can improve the dispersion effect of glow in the dark powder and improve the appearance and color of products.
  1. Selection of coupling agent: Before adding the luminescent pigment to the resin, it should be treated with a coupling agent, and then mixed with the resin and additives to enhance the mechanical properties of the luminescent plastic product.
  1. Selection of stabilizer and antioxidant: For polyolefin resin, 0.6% antioxidant can be added, and AT168 and AT1010 can be added. For ABS resin, an appropriate amount of antioxidants can also be added, and the added amount can be less than 0.6%.

B. In terms of technology: The following is the case:

  1. Equipment with a relatively small long diameter should be selected. If the equipment cannot be changed, the temperature of the feeding section and the conveying section can be appropriately increased (2-3 ℃).
  1. The speed of the host should be 15% to 20% higher than the speed under normal conditions to increase the material running speed.
  1. When mixing the materials, do not subject the luminescent powder to any strong shear and friction on the high mixer or high mixer. At the same time, ceramic or glass containers should be used when mixing.
