Problems solved by technology

The exposed installation method leads to bending and irregular cable routing, and various uncontrollable external factors lead to high safety risks and reduced reliability; the installation method of PVC round protection tube causes cables to cross and squeeze each other in the protection tube , and due to factors such as ambient temperature and overload during operation, the cable is prone to heat, causing a short-circuit fault and causing the cable to burn
[0003] Existing cable trays are generally made of metal materials. Although the overall strength and flame retardancy are high, they are easily corroded and affect the service life when used in some harsh environments; non-metallic cable trays have strong anti-corrosion performance, but Not enough mechanical strength

Abstract

The invention discloses a high-strength glass fiber AS reinforced plastic bridge and a preparation method thereof. The high-strength glass fiber AS reinforced plastic bridge comprises the following components in weight part: 75-85 parts of AS resin, 20-25 parts of a glass fiber-polyvinyl alcohol composite solution, 0.5-1 part of magnesium oxide, 0.5-2 parts of a curing agent, 6-8 parts of a flameretardant agent and 3-5 parts of fillers. A preparation method of the glass fiber-polyvinyl alcohol composite solution comprises the following steps: 1) adding polyvinyl alcohol powder into water of 30-35 DEG C, stirring for 10-15 minutes, slowly increasing the temperature to 70-85 DEG C, performing heat preservation for 3-4 hours and ensuring the complete dissolution of PVA to prepare 5-10 percent by weight of polyvinyl alcohol aqueous solution; 2) in the case of ultrasonic agitation, dispersing glass fibers in the polyvinyl alcohol aqueous solution to form the glass fiber-polyvinyl alcohol composite solution; and the mass ratio of the glass fibers to the polyvinyl alcohol aqueous solution is 45-50 to 100.

Description

technical field [0001] The invention relates to a high-strength glass fiber AS reinforced plastic bridge frame. Background technique [0002] At present, all aspects of life are increasingly inseparable from electricity. In the infrastructure construction of power supply, safety and reliability are important factors in the construction of power infrastructure. The exposed installation method leads to bending and irregular cable routing, and various uncontrollable external factors lead to high safety risks and reduced reliability; the installation method of PVC round protection tube causes cables to cross and squeeze each other in the protection tube , and due to factors such as ambient temperature and overload during operation, the cable is prone to heat, resulting in a short-circuit fault that causes the cable to burn.
