Bonding technology of steel-glass reinforced plastic composite material for tank path and tank path beam

Abstract

The invention discloses a bonding technology of a steel-glass reinforced plastic composite material for a tank path and a tank path beam. The bonding technology comprises the following steps: firstly, selecting steel material, carrying out alkali washing, acid washing, sand beating and passivation; coating the surface of the steel material after being processed with a coupling agent; coating a parting agent on a mould, dipping glass fibre cloth in gum, and filling the glass fibre cloth after gum dipping into a mould cavity of the mould; pressing the steel material in the center of the mould, compacting to manufacture a product, removing, stripping mould t after natural curing is carried out for 20 to 50 minutes, and flatly placing the manufactured product after mould stripping and then fully curing naturally. The coupling agent is used as a first layer of isolation for enhancing the bonding force between the steel material and glass reinforced plastics, and specially prepared glue liquid with strong bonding force is used for isolating the steel material and outside oxygen and is used as a second layer of isolation. By adopting glass reinforced plastic fibre multi-layer protection, on one hand, striking force is dispersed in the collision process, and on the other hand, the oxidation of the steel material is avoided. The invention solves the problem of the bonding of glass reinforced plastics and square steel, saves energy, lowers consumption, reduces pollution and obtains a favorable renovation benefit.

Description

technical field [0001] The invention relates to a steel-glass reinforced plastic composite material bonding process, in particular to a steel-glass reinforced plastic composite material bonding process for tank roads and tank road beams in mines. Background technique [0002] The tank road in the mine is actually a special elevator passage. Compared with the general elevator shaft, it has higher requirements for safety, water resistance and corrosion resistance. The existing tank roads are made of steel-glass reinforced plastic composite materials, but The existing technology is immature for the bonding process of FRP and square steel, and the impact of thermal expansion and contraction often causes the FRP and square steel to shell, reducing the service life of the FRP tank. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel-glass reinforced plastic composite material bonding process with stronger bonding, ...

Problems solved by technology

[0002]The tank road in the mine is actually a special elevator passage, which has higher requirements on safety, water resistance and corrosion resistance than ordinary elevator shafts. The tanks are all made of steel-glass reinforced plastic composite materials, but the existing technology is immature for the bonding process of glass fiber reinforced plastic and square steel, and the impact of thermal expansion and contraction often makes glass steel and square steel shell off, reducing the quality of glass fiber reinforced plastic tanks.
