A high thermal conductivity, high performance glass fiber reinforced polyester alloy composite material

Abstract

This invention belongs to the field of mixing equipment technology, specifically a high thermal conductivity, high-performance glass fiber reinforced polyester alloy composite material, with the following weight percentage components: glass fiber 38-44%; unsaturated polyester resin 26-30%. Through the structural design of the scraper, during mixing, the motor is started, driving the first stirring shaft and the first stirring rod to rotate at high speed to mix the raw materials. Due to the high-speed rotation of the first stirring shaft, the centrifugal force of the fixed block is large, causing the fixed block to rotate around the top pin. The rotating block can drive the first gear to move upwards, causing the first gear to disengage from the second gear, thus preventing the scraper from rotating. After mixing is completed, material adheres to the inner wall of the mixing tank and needs to be cleaned. The motor is started, driving the first stirring shaft to rotate at low speed, resulting in a smaller centrifugal force. The first gear remains engaged with the second gear, causing the scraper to rotate, thus achieving the function of scraping and cleaning the inner wall of the mixing tank.
