Abstract

The invention relates to a semiconductor adhesive film material and a preparation method thereof, particularly a semiconductor adhesive film material for preparing lightning-protection shunt bars and a preparation method thereof. The invention aims to solve the technical problems of complex technique, incompatibility and nonmatching property caused by co-gluing or secondary gluing when other adhesives are adopted in the existing technique. The material is composed of the following components in parts by weight: 75-100 parts of epoxy resin, 15-30 parts of thermoplastic resin, 6-12 parts of rubber elastomer, 15-25 parts of curing agent, 2-6 parts of accelerator, 6-12 parts of non-metal conducting filler and 10-20 parts of non-metal semiconductor filler. The method comprises the following steps: 1. weighing; 2. preparing a resin mixture; 3. blending and discharging; and 4. calendering to form the film. The semiconductor adhesive film material has the characteristics of the structural adhesive film and also has the characteristic of resistance value of the semiconductor adhesive material. The semiconductor adhesive film material is used for preparing lightning-protection shunt bars.

Description

technical field [0001] The invention relates to a semiconductor adhesive film material and a preparation method thereof. Background technique [0002] The aircraft radome is generally located at the front of the aircraft. It is required that the radome not only ensures the smooth passage of radar electromagnetic waves, but also protects the radar antenna from the harmful effects of external loads (such as wind, rain, sand, dust, lightning, etc.). important part of the body. In order to ensure that electromagnetic waves pass through the radomes smoothly, most radomes are made of dielectric materials. Dielectric materials are poor conductors of electricity, and the aircraft radome is located on the most vulnerable position on the aircraft to be attacked by lightning, so the industry generally uses lightning shunt strips for protection. [0003] The radome lightning protection system is generally composed of conductive or semi-conductive materials, such as compounding metal f...
