Problems solved by technology

Pedals made of metal materials such as steel plates, steel grids, and aluminum plates have high strength, good load-bearing capacity, and long service life, but their unit weight increases, resulting in increased labor intensity for workers' transportation and maintenance, and high production and use costs. , and it is easy to rust when used outdoors for a long time, which eventually leads to low cost performance
Materials such as moso bamboo board or bamboo plywood have average strength, poor weather resistance, non-wear resistance, easy combustion, potential safety hazards, and short service life. Although the manufacturing cost is low, the use cost is relatively high, so it is not suitable for modern building materials development needs
[0004] Chinese invention patent CN201310089606.2 discloses a scaffold pedal material and its preparation method. The pedal material is based on polyolefin

Abstract

The invention discloses a high-strength environment-friendly scaffold pedal and a preparation method thereof, and relates to the technical field of building board production. The high-strength environment-friendly scaffold pedal disclosed by the invention is prepared from polyvinyl chloride, modified plant fibers, polyamide resin, butadiene-styrene copolymer emulsion, metakaolin, silica fume, hexamethylphosphoramide, an ultraviolet light absorber, a heat stabilizer and a lubricant through the steps of PVC-bs-PA blend preparation, blending, granulation and the like. The modified plant fibers are prepared by carrying out surface modification on plant fibers under the action of diacetone alcohol and a silane coupling agent. According to the high-strength environment-friendly scaffold pedal, the raw materials are easy to obtain, the preparation process is simple and easy to operate, the cost is low, the high-strength environment-friendly scaffold pedal has excellent mechanical strength, impact resistance, flame retardance, wear resistance, corrosion resistance and weather resistance, and the service life of the scaffold pedal is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building plate production, and in particular relates to a high-strength environment-friendly scaffolding pedal and a preparation method thereof. Background technique [0002] Scaffolding is a construction support on a building construction site, and it is also a construction equipment often used in decoration engineering and maintenance engineering. It is mainly used to provide pedestrian passages, a small amount of stacked materials and safety protection. Scaffolding can be divided into wooden scaffolding, bamboo scaffolding and steel pipe scaffolding according to different materials, and wooden scaffolding and bamboo scaffolding are generally used in construction sites, decoration sites and maintenance sites of lower buildings due to their limited load-bearing capacity. With the acceleration of the country's urbanization, a large number of high-rise and super high-rise buildings have emerged. Existing s...
