Molded glass fiber-reinforced plastic cable bridge

Abstract

The invention discloses a molded glass fiber-reinforced plastic cable bridge. The molded glass fiber-reinforced plastic cable bridge is prepared from, by weight, 50-75 parts of ABS resin, 35-55 partsof modified glass fiber complex liquid, 4-7 parts of rectorite, 3-6 parts of magnesium oxide, 3-5 parts of a curing agent, 6-12 parts of a flame retardant, 5-8 parts of an accelerating agent and 1-3 parts of an antistatic agent, wherein the preparation method of the modified glass fiber complex liquid comprises the steps of preparation of a modifying agent, preparation of a modifying agent hydrolysate and preparation of the modified glass fiber complex liquid. The preparation method comprises the specific steps that 20-50 parts of glass fibers are subjected to heat treatment, wherein accordingto the heat treatment conditions, the glass fibers are fired for 20-30 minutes at the temperature of 600 DEG C in the nitrogen atmosphere, absorbed water and impurities on the surface of the glass fibers are removed, 30-50 parts of the modifying agent hydrolysate and 8-15 parts of polyether urethane are added immediately, and evenly mixed in a high-speed mixing machine, and the modified glass fiber complex liquid is obtained. The modified glass fibers are bonded to the surface of an ABS resin matrix, low critical surface tension is obtained, and due to the low critical surface tension, the glass fiber-reinforced plastic cable bridge is high in hydrophobicity and obviously higher in corrosion resistance.

Description

technical field [0001] The invention relates to a shaped fiberglass cable bridge. 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. The cable tray came into being, and the cable tray is a carrier for carrying various cables, which is generally applicable to large enterprises, large-scale engineering transformation, c...

Problems solved by technology

[0003] Traditional cable bridges generally use metal bridges and stainless steel bridges. Among them, metal bridges are generally made of thicker steel plates in order to increase their bearing capacity. For steel bridges, the cost increases, and the processing is also difficult. It cannot be installed in an environment with fire protection requirements. Aluminum alloys are prone to deformation and loss of alloy elements when exposed to high temperatures;

[0004] Existing fiberglass bridges are generally composed of glass fiber reinforced plastics, flame retardants and other materials. Compared with traditional metal bridges and stainless steel bridges, they are more lightweight and corrosion-resistant; but the combination of glass fiber and resin There are generally large defects between the composite interfaces, which often lead to the decline of the overall strength and structural performance of the bridge.
