Problems solved by technology

[0002] At present, the telescopic movable guardrails at the opening of the central isolation belt of the expressway and the gates of enterprises, institutions, and living quarters are made of stainless steel or carbon steel as raw materials through cutting, bending, welding, drilling, grinding and other mechanical processing techniques. , the raw material price and processing cost are high, the guardrail is in the open air for many years, exposed to the sun and rain, easy to rust and needs regular anti-rust and other maintenance; and because it is a metal product, the recycling value is high, and the phenomenon of being stolen and bought often occurs , there is a safety hazard caused by man-made damage

Abstract

An unsaturated polyester resin fence comprises the following raw materials at the mixture ratio of: 20-40 percent of unsaturated polyester resin, 2-6 percent of polystyrene, 2-6 percent styrene, 5-30 percent of chopped glass silk, 25-40 percent of ground calcium carbonate, 1-1.5 percent of pigment, 2-4 percent of curing thickener, 3-4 percent of flame retardant and 3-4 percent of ultraviolet light resistant agent. The polystyrene is diluted by the styrene, all components are stirred uniformly pro rata, pressed by a die and heated, and the temperature and pressure are maintained for curing and forming, then the flash is removed after demoulding and the edges and corners are polished to form the members of the fence; the bottom is provided with rolling wheels, and jointing and splicing are conducted to assemble a set of retractable moving fence which has high strength, no toxicity or pollution, corrosion resistance, beautiful appearance, low production cost, convenient assembly and is applicable at the openings of the central isolation belts of highways.

Description

technical field [0001] The invention belongs to a road traffic safety protection facility and a manufacturing method thereof, in particular to an unsaturated polyester resin guardrail and a manufacturing method thereof. Background technique [0002] At present, the telescopic movable guardrails at the opening of the central isolation belt of the expressway and the gates of enterprises, institutions, and living quarters are made of stainless steel or carbon steel as raw materials through cutting, bending, welding, drilling, grinding and other mechanical processing techniques. , the raw material price and processing cost are high, the guardrail is in the open air for many years, exposed to the sun and rain, easy to rust and needs regular anti-rust and other maintenance; and because it is a metal product, the recycling value is high, and the phenomenon of being stolen and bought often occurs , Man-made damage and potential safety hazards. How to reduce the production cost and ...
