FRP panel material for power cabinet

Abstract

The invention discloses a special glass fiber reinforced plastic panel material of an electric cabinet. The panel material is manufactured by using the following raw materials in parts by weight: 30-35 parts of epoxy acrylic resin, 30-40 parts of glass fiber, 3-5 parts of furane resin adhesive, 2-4 parts of polytetrafluoroethylene, 0.1-0.3 part of graphite powder, 1-2 parts of curing agent and 2-4 parts of titanium dioxide powder. The special glass fiber reinforced plastic panel material has the technical effects that the manufactured panel material is small in density, light in weight, high in hardness, good in toughness, good in electric insulation, good in fire resistance, corrosion resistance, abrasive resistance and antistatic capability, time-saving and labor-saving to mount, safe and reliable; the service life of the electric cabinet is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric equipment shells, and relates to a panel material, in particular to a glass fiber reinforced plastic panel material for electric cabinets. Background technique [0002] The current power cabinet shell is mainly made of cold-rolled steel plate or stainless steel plate. The cold-rolled steel plate has high strength and bright surface, but its toughness and weldability are poor. It is relatively hard and brittle. If there is a missing weld, water will enter , causing the components inside the power cabinet to be scrapped or even a fire, which poses a safety hazard. The stainless steel plate has sufficient strength, excellent plasticity, low hardness, and is easy to process. However, due to the long-term outdoor and poor environment, the corrosion resistance cannot well meet the needs of use, which makes the service life of the power cabinet Short, especially the acid rain formed after the rain is e...

Problems solved by technology

[0002] The current power cabinet shell is mainly made of cold-rolled steel plate or stainless steel plate. The cold-rolled steel plate has high strength and bright surface, but its toughness and weldability are poor. It is relatively hard and brittle. If there is a missing weld, water will enter , causing the components inside the power cabinet to be scrapped or even a fire, posing a safety hazard

The stainless steel plate has sufficient strength, excellent plasticity, low hardness, and is easy to process. However, due to the long-term outdoor and poor environment, the corrosion resistance cannot well meet the needs of use, which makes the service life of the power cabinet Short, especially the acid rain formed after the rain is extremely corrosive to the outer surface of the power cabinet. Once the power cabinet is corroded, the power system will face great danger

Other power cabinets are used to carry high-voltage power supplies. The current power cabinets are generally made of iron sheets, especially in the dry north, where static electricity is often generated due to dust friction, which makes the high-voltage power supply cabinets extremely prone to fire hazards, and the consequences are disastrous.

Moreover, the density of the stainless steel plate is relatively high, it is time-consuming and laborious to install, the electrical insulation is poor, and there are also potential safety hazards.
