Glass fiber reinforced plastic adhesive boundary sign bracket and production method thereof

Abstract

The invention relates to a glass fiber reinforced plastic adhesive boundary sign bracket and a production method thereof. The bracket is of a moulding integral structure, a panel on the upper part ofthe bracket is in the shape of a table tennis racket, a base on the lower part of the bracket is in the shape of a concave groove plate, and the longitudinal cross section of the bracket is in an L shape. The invention comprises the following raw materials and steps: taking unsaturated polyester resin, polystyrene and styrene polymer solution, chopped glass fiber, packing, carbon black, curing agent, zinc stearate and the like as raw materials; firstly, preparing polystyrene and styrene into a polymer solution for standby; then, uniformly mixing the seven raw materials; and finally, filling the raw materials in a metal mould to cure and form the raw materials through pressurization and heating, and then depanning and tripping the formed materials. A reflection film is stuck on the bracketto form an adhesive boundary sign. The bracket has the advantages of smooth surface, high strength, favorable performance of corrosion resistance and aging resistance, low cost and long service life,and avoids pilferage because of no recycling value. The invention greatly reduces cost in purchase and maintenance.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic attachment type delineator bracket and a production method thereof. Background technique [0002] At present, the attachment delineator used to indicate the direction and boundary of the road is installed on the corrugated beam of the wave guardrail or on the concrete guardrail and the guardrail of the urban traffic passage on the expressway. The support material is generally aluminum alloy plate or carbon steel plate. Stamping molding, also available PVC plastic injection molding. Aluminum alloy plates are expensive; carbon steel plates are also expensive, and hot-dip galvanized surface treatment is required for anti-corrosion, so the cost is also close to that of aluminum alloy plates. In the harsh outdoor environment, the attached contour markers of the two metal materials are easily corroded, and the service life is not long. At the same time, metal materials have high recycling value and ...

AI Technical Summary

Problems solved by technology

In the harsh outdoor environment, the attached contour markers of the two metal materials are easily corroded, and the service life is not long

At the same time, metal materials have high recycling value and are prone to theft

Although the PVC plastic delineator has good corrosion resistance, it has poor strength and is easy to break and damage; and it has poor anti-aging performance. After a period of use, it will appear chalking, discoloration, and cracking, and it is easier to break and needs to be replaced frequently.
