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 of the 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
The present invention relates to a kind of glass fiber reinforced plastic adhesive boundary sign bracket and production method thereof.
Background technology
At present, speedway be installed on the corrugated guardrail wave beams or be installed on the concrete guardrail and urban traffic passage guardrail on the adhesive boundary sign in order to indication road direction of advance and border, its timbering material is generally aluminium alloy plate or carbon steel plate punch forming, also useful PVC injection molding.Aluminium alloy plate costs an arm and a leg; The carbon steel plate price is also high, also must carry out the galvanizing by dipping surfacing for anticorrosion, so cost is also near aluminum alloy plate materials.Under the open-air out of doors adverse circumstances, the adhesive boundary sign of two kinds of metal material all is corroded easily, and application life is not long.Simultaneously, steal phenomenon also takes place in metal material recovery value height easily.Though the profile of PVC plastics mark decay resistance is better, intensity difference, frangibility is damaged; And ageing resistace is poor, efflorescence, variable color, crack performance can occur after use a period of time, and frangibility needs often to change more.
