Abstract

The invention belongs to the technical field of power towers, and particularly relates to an external protection layer material formula for a composite material tower. The external protection layer material comprises the following raw materials in parts by weight: 1000 to 2000 parts of an adhesive, 1000 to 1500 parts of a curing agent, 4 to 6 parts of an accelerant, 4000 parts of filler, 20 to 60parts of a flame retardant, 7 to 15 parts of a coloring agent, 4 to 5 parts of a coupling agent, 11 to 15 parts of s stress absorbent and 1.8 to 3.9 parts of an adhesion assistant. By adopting the external protection layer material formula, the defects in the prior art are overcome. The adhesive, the curing agent, the accelerant, the filler, the flame retardant, the coloring agent, the coupling agent, the stress absorbent and the adhesive assistant are combined, so that the external protection layer material has the advantages of high collision resistance, corrosion resistance, oxidation resistance and flame retardance.

Description

technical field [0001] The invention belongs to the technical field of power poles and towers, and in particular relates to a material formula for the external protective layer of a composite material poles and towers. Background technique [0002] Transmission line tower structure is a special support structure in power overhead line facilities, and its structural performance directly affects the safety, economy and operational reliability of the line. With the development of my country's power grid, transmission line engineering presents a trend of long-distance, large-scale and large-scale development. At present, transmission line towers are generally composed of steel and concrete. In particular, the use of a large number of steel structure poles and towers has increased the demand for steel products year by year, consuming a large amount of mineral resources and causing pollution to the ecological environment. At the same time, a large number of steel materials are u...
