Problems solved by technology

[0002] At present, many fields need to use various sign boards, especially in the transportation field. Most of the existing sign boards are made of aluminum alloy sheets, resulting in the consumption of a large amount of aluminum alloy materials. In addition, the price of aluminum alloy materials is relatively high, and the price of one square meter of materials is nearly 300 yuan, the cost is high, because the aluminum plate is expensive and the recycling value is high, a small number of criminals use the stealing sign as a way to make money, causing great losses, and also bringing unsafe hidden dangers

Embodiment 1

[0025] Use large molds to make FRP grid panels, and determine the number of embedded U-bolts according to the molding size, pre-embed U-shaped bolts in the FRP grid panels according to the required number, and cut the finished FRP grid panels to the required size The regular hexagon, using a punching machine to process the metal plate into a shape that matches the FRP grid plate, mix the epoxy resin glue and polyamide resin evenly at a mass ratio of 1:1, and then combine the FRP grid plate and the metal plate Paste them together so that the metal plate is covered on the front surface and side of the FRP grid plate and form an edge on the back, pressurize with a press, and the pressure is controlled at about 0.6MPa, and then cured at room temperature for 2 hours. The first and second slots are respectively installed on the U-shaped bolts and fastened by nuts to obtain the FRP composite traffic signboard of the present invention, whose main properties are shown in Table 1.

Embodiment 2

[0027] Use a mold that matches the required FRP grid plate to make the FRP grid plate. A pair of iron plates and a pair of U-shaped bolts are embedded in the left and right sides of the FRP grid plate, and the metal plate is processed by a punching machine. To match the shape of the FRP grid plate, mix epoxy resin glue and T31 epoxy resin curing agent evenly at a mass ratio of 1:0.1, and then paste the FRP grid plate and the metal plate together so that the metal plate is covered The front surface, sides and back of the FRP grid plate are bounded, pressurized with a press, the pressure is controlled at about 4.9MPa, and then cured at room temperature for 1 hour, and the first and second slots are respectively installed on the On the U-shaped bolts and fastened by nuts, the FRP composite traffic signboard of the present invention is obtained, and its main properties are shown in Table 1.

Abstract

The invention belongs to the technical field of road signboards and aims at providing a glass fiber reinforced plastic composite material traffic signboard which has low cost, excellent performances and guarantees safety and a manufacturing method thereof. The glass fiber reinforced plastic composite material traffic signboard comprises a glass fiber reinforced plastic grid plate and a metal plate, wherein the metal plate covers the front surface and the side edge of the glass fiber reinforced plastic grid plate, and a covering edge is formed on the back surface of the glass fiber reinforced plastic grid plate; the metal plate and the glass fiber reinforced plastic grid plate are stuck and fixed; a light-reflection membrane is stuck on the front surface of the metal plate; and a first clamping groove and a second clamping groove are formed in the back surface of the glass fiber reinforced plastic grid plate. The glass fiber reinforced plastic composite material traffic signboard provided by the invention is formed by compounding and molding the metal plate and the glass fiber reinforced plastic grid plate; the whole structure has rigidity and toughness and expresses the performances of tension resistance, pressing resistance, bending resistance, and weight which is lighter than an aluminum plate of the glass fiber reinforced plastic grid plate; the attaching performances of the metal plate and the light-reflection membrane are kept, and functional requirements of an existing signboard can be met; the construction cost is greatly reduced and a valuable resource of aluminum alloy sheet materials is saved; and the glass fiber reinforced plastic composite material traffic signboard is economical and environmentally friendly and is not easy to steal, and guarantees the safety.

Description

technical field [0001] The invention belongs to the technical field of road signboards, in particular to a method for making a traffic signboard made of glass fiber reinforced plastic composite material. Background technique [0002] At present, many fields need to use various sign boards, especially in the transportation field. Most of the existing sign boards are made of aluminum alloy sheets, resulting in the consumption of a large amount of aluminum alloy materials. In addition, the price of aluminum alloy materials is relatively high, and the price of one square meter of materials is nearly 300 yuan, the cost is high, because the aluminum plate is expensive and the recycling value is high, a small number of criminals take the theft of signboards as a way of making money, causing great losses, and also bringing unsafe hidden dangers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for making a traffi...
