Flame-retardant optical transparent PP material and preparation method thereof

[0055] The present invention also provides a method of preparation of flame retardant optical transparent PP material, including the following steps:

[0056] S1: Place the PP raw material to dry 3-6 hours in a hot air box of 80 ° C;

[0057] S2: Treatment of the coupling agent and the heat stabilizer for 30 minutes, so that the coupling agent and the heat stabilizer reaches a diameter of 10-30 nanometers; an aerosolization increases the coupling agent and The specific surface area of ​​the heat stabilizer, thereby increasing the contact area of ​​the phosphorus nitrogen-based mixed flame retardant, which can increase the contact area of ​​the PP raw material to the flame retardant, so that the PP and the flame retardant are mixed more uniform, and also Increases the molecular action between PP and flame retardants;

[0058]S3: After stirring the penetrating agent and a phosphorus nitrogen-based mixed flame retardant for 20 minutes by low speed mixing tub, the high-frequency powder c
