A scratch-resistant composite pole and its manufacturing method

Abstract

The invention relates to the technical field of electric poles, and discloses a scratch-resistant composite material electric pole and a manufacturing method thereof. The scratch-resistant composite material electric pole comprises a fiber layer, a resin layer, a scratch-resistant layer, a protective layer and a texture layer, wherein the fiber layer formed by cross-winding fiber yarns on the outer surface of a core mold of the electric pole by adopting a fiber yarn spiral winding process; the resin layer formed by uniformly spraying resin on the outer surface of the fiber layer; a particulatematter is added to the resin in advance, the particulate matter is sprayed along with the resin so as to form the scratch-resistant layer on the outer surface of the resin layer; the particulate matter penetrates into the internal part of the resin layer, the resin layer wraps the particulate matter and forms the thin resin protective layer outside the particulate matter; and the protective layeris externally wrapped by a layer of de-molding cloth, and the texture layer is formed after tearing off the de-molding cloth. The process steps are greatly reduced, the production efficiency is improved, and the production cost is reduced. In addition, the protective layer is externally wrapped by the layer of de-molding cloth, thereby greatly improving the friction received by the electric pole,and improving the scratch resistance of the electric pole.

Description

technical field [0001] The invention relates to the technical field of electric poles, in particular to a scratch-resistant composite electric pole and a manufacturing method thereof. Background technique [0002] General wooden or cement poles have disadvantages such as heavy weight and short life. After the pole is exposed to the sun and rain, the degree of corrosion will become higher and the life will be shortened; at the same time, the general composite pole , the surface of the pole is smooth or shows entanglement of fiber yarn. In dry weather, maintenance personnel can barely climb the pole to work, but in rainy and wet weather, maintenance personnel are prone to slipping when climbing the pole, which will give Maintenance personnel bring certain potential safety hazards.

[0002] General wooden or cement poles have disadvantages such as heavy weight and short life. After the pole is exposed to the sun and rain, the degree of corrosion will become higher and the life will be shortened; at the same time, the general composite material pole , the surface of the pole is smooth or shows entanglement of fiber yarn. In dry weather, maintenance personnel can barely climb the pole to work, but in rainy and wet weather, maintenance personnel are prone to slipping when climbing the pole, which will cause damage to the pole. Maintenance personnel pose certain safety hazards

[0003] However, most of the current anti-slip poles use particles exposed on the outer surface or a protective layer is provided on the outer surface of the particles. The particles of the former poles are easy to fall off due to scratches. During the construction process, the particles are seriously lost and the anti-skid effect is greatly reduced. , while the latter has a complicated process, which is not conducive to mass production, and the consumables are also serious, and the cost is high

[0004] Chinese patent CN201721445998.1 is a kind of anti-skid electric pole made of composite material. By exposing the particles or re-spraying a protective layer or heating the resin layer to wrap the particles, the exposed particles are easy to cause the particles to fall off and are not scratch-resistant. Instead, the resin is sprayed or heated. , the process is complicated and cumbersome, which is not conducive to mass production, and the cost is high, and because the anti-slip layer is uneven, there will be gaps between the additional sprayed protective layer and the resin layer, which is easy to enter the air, and the protective layer cannot be closely attached to the particles and the resin layer , easy to fall off, no protection
