Problems solved by technology

After searching, it is found that no one has used aluminum hydroxide as a modifier in the field of FRP radome. If the characteristics of aluminum hydroxide can be introduced into the FRP radome material, it can solve the problem of CaCO 3 As a filler, the DK value is high, and the mechanical properties of the material can also be improved.

Abstract

The invention discloses a glass fiber reinforced plastic antenna housing modified by aluminum hydroxide, which has the advantages of reducing DK value thereof and improving the wave penetrating property of the product. The glass fiber reinforced plastic antenna housing modified by aluminum hydroxide is prepared from the following raw materials in part by weight: 100 parts of unsaturated polyester, 5 to 30 parts of aluminum hydroxide, 0.5 to 2 parts of releasing agent, 0.5 to 2 parts of curing agent and 0.5 to 2 parts of accelerant.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic radome and a preparation method thereof, in particular to a glass fiber reinforced plastic radome modified with aluminum hydroxide material 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 shell of wireless and mobile communication base station antennas. FRP radome is generally extruded with unsaturated polyester as the main raw material and then added with fillers and related additives. Unsaturated polyester (abbreviated UP) mainly refers to the combination of diol and all or part of unsaturated dibasic acid. The resin obtained by condensation polymerization usually has good heat resistance, insulation, water resistance, chemical resistance, and aging resistance, and the reinfor...
