Embodiment 1
[0062] The production method of the PP diffuser plate of the display backlight source and the LED flat panel lamp includes the following steps:
[0063] In the steps of preparing the main material, PP plastic granules are selected as the main material;
[0064]In the step of making the optical master batch, the components of the optical master batch include by weight:
[0065] 40-90 parts of this material and 10-60 parts of light-transmitting plastic selected from 100 parts of this material, the light-transmitting plastic includes at least one light-transmitting plastic whose optical refractive index is different from that of the material, Wherein, the translucent plastics made of optical master batch include one or more mixtures of silicone microspheres, MS microspheres, PS microspheres, PS plastic particles, PE plastic particles and MS plastic particles;
[0066] The components of the optical master batch are uniformly stirred and mixed and then put into a twin-screw granul...
Embodiment 2
[0075] The main steps and processes of the present embodiment are the same as those of the first embodiment, and will not be repeated here, but the difference lies in the selection of the components and the corresponding ratio:
[0076] In the steps of preparing the main material, 100 parts of PP plastic particles are selected as the main material according to the weight ratio;
[0077] In the step of making optical masterbatch, the optical masterbatch is composed of the following two weight ratio components:
[0078] 60 original materials selected from 100 original materials,
[0079] 40 parts of silicone microspheres;
[0080] After evenly stirring and mixing, put into a twin-screw granulator to manufacture optical master batches, and make optical master batches with a total weight ratio of 100 parts;
[0081] At least 0.001-0.05 part of lubricating and dispersing agent and 0.001-0.05 part of toughening agent are added in the process of manufacturing optical master batch b...
