| titleOfInvention | Weather-resistant and flame-retardant PC composite material for radome and preparation method thereof |
| abstract | The application relates to the field of polymer composite materials, in particular to a weather-resistant and flame-retardant PC composite material for a radome and a preparation method thereof. In parts by weight, the raw materials for preparing the weather-resistant and flame-retardant PC composite material for radomes include: 50-70 parts of siloxane-containing PC powder, 15-40 parts of siloxane powder, 0.3-1 part of pentaerythritol stearate, 0.8-2 parts of burning agent, 0.6-2 parts of antioxidant, 5-8 parts of acrylic impact modifier with core/shell structure, 0.5-1 part of polytetrafluoroethylene powder; the siloxane-containing PC powder is 300 parts The melt mass flow rate at ℃ and 1.2kg is 3.8-4.2g/10min. The weather-resistant and flame-retardant PC composite material for the radome prepared in the present application has good mechanical properties, thermal properties and flame-retardant properties, greatly reduces the amount of flame retardants, achieves a flame-retardant degree of V0 at a thickness of 0.9 mm, and reduces the impact on the antenna. The cover has good corrosion resistance and good weather resistance, and meets the requirements of weather resistance and flame retardant performance of 5G wireless base station radomes. |
