Abstract

The invention discloses a fiberglass radome modified by PE micro powder, which reduces the DK value thereof, and improves the wave penetration performance of the products. The fiberglass radome modified by PE micro powder is prepared by the following raw materials in weight portion: 100 portions of unsaturated polyester, 3-15 portions of PE micro powder, 0.5-2 portions of mold release agent, 0.5-2 portions of curing agent and 0.5-2 portions of accelerator.

Description

Technical field [0001] The invention relates to a glass fiber reinforced plastic antenna cover and a preparation method thereof, and more specifically to a glass fiber reinforced plastic antenna cover modified with PE micropowder and a preparation method thereof. Background technique [0002] Due to the advantages of good weather resistance, insulation, light weight, high strength, stable size and high production efficiency, FRP radome has been widely used in many fields such as the protective housing of wireless and mobile communication base station antennas. Those of ordinary skill in the art know that glass fiber reinforced plastic radomes are made of glass fiber plus auxiliary materials (impregnated materials). Since glass fiber is relatively stable, the modification of glass fiber reinforced plastic radome is generally to modify the auxiliary materials to achieve glass fiber reinforced plastics. The performance requirements of the radome; for example, the relevant content of...
