Special plastic steel cable bracket and manufacturing process thereof

Abstract

The invention provides a special plastic steel cable bracket and a manufacturing process thereof. The formulation of the bracket comprises the following components in portion by weight: 100 portions of pultrusion resin, 2 portions of talc powder, 10 portions of aluminum powder, 5 portions of bromo-diphenyl ether, 0.5 portion of zinc powder, 0.5 portion of mold oil, 2.0 portions of pigment, 1 portion of methyl ethyl ketone, and 0.8 portion of tert-butyl ester. The process comprises the following steps: taking the pultrusion resin and putting the same in a mixer first, adding the talc powder, the aluminum powder, the bromo-diphenyl ether, the zinc powder, the mold oil and the pigment into the resin, and mechanically stirring the mixture evenly; taking the methyl ethyl ketone and the tert-butyl ester to mix with the prepared material, and stirring the mixture evenly; passing twistless roves through a yarn guide plate and a preforming die, then passing the twistless roves through a die to a clamping device and tightly twining the twistless roves with a twisting band, and putting the tightly twined roving heads into the clamping device and clamping the roving heads tightly to perform traction; pressing the roves into a material soaking basin, clamping the roves tightly with clamping rods, putting the roves into a die after sufficient soakage, and adding a glass fiber mat; and after the fibers of a band material enter the die, heating the die so that the resin is solidified into a formed product. The manufacturing process is simple, and the 'performance price ratio' is far higher than that of the conventional steel bracket or the brackets made of other materials.

Description

technical field [0001] The invention relates to a special plastic steel cable bracket and its manufacturing process. Background technique [0002] At present, various cables are used more and more widely, and they are placed in rows and bundles on cable brackets in a centralized way. Cable brackets are one of the best ways to lay cables. They have been used in factories, mines, enterprises, Widely used in engineering equipment to improve space utilization. Cable trays are usually made of glass fiber reinforced plastics and manufactured by compression molding. Manufactured by this method, the width of the cable bracket should not be too large, usually the width of the cable bracket is 50-100 mm, therefore, it cannot bear too much external force in the horizontal direction, and it is often used when the cable is pulled or the cable creeps in the horizontal direction. Damage, thereby increasing the cost of cable maintenance. [0003] At present, the most widely used cable br...

Problems solved by technology

However, the impact strength of the ceramic cable bracket is poor, fragile and easy to break, and it is easy to break and break during the laying of the project; the cost of the aluminum cable bracket is high, and the structural strength is low

Not only that, when the steel cable bracket, galvanized sheet cable bracket and aluminum cable bracket are installed and used, if the construction personnel accidentally damage the insulation layer of one phase of the cable during the cable laying process, it will cause the Phase-to-ground affects operation
