A sandwich layer composite light pole and its rapid prototyping method

Abstract

The invention discloses a composite interlayer material lamp rod and a quick molding method thereof. The composite interlayer material lamp rod is mainly applied to electric power supporting structure engineering. The composite interlayer material lamp rod comprises an inner skin layer, an outer skin layer and an interlayer arranged between the inner skin layer and the outer skin layer; the composite interlayer material lamp rod is characterized in that the interlayer is compounded by a bamboo curtain and an unsaturated polyester resin glue solution. The quick molding method comprises the following steps: a step of molding the inner skin layer on a mold coated with a mold release agent and a step of molding the outer skin layer on the surface of the interlayer, and further comprises the steps as follows: (1) paving the bamboo curtain on the upper surface of the inner skin layer; (2) filling a gap between two adjacent bamboo strips of the bamboo curtain with the unsaturated polyester resin glue solution; (3) intertwining a basalt fiber yarn molding outer skin layer dipped by the unsaturated polyester resin glue solution on the bamboo curtain; (4) intertwining de-mold cloth on the surface of the outer skin layer, de-molding after solidifying, and molding the composite interlayer material lamp rod once. The composite interlayer material lamp rod has acid resistance, alkali resistance, light weight, less deformation and low cost, is quickly molded and is suitable for popularization and application.

[0002] In the prior art, light pole products are mostly made of metal light poles. Metal light poles have the characteristics of high strength, short molding cycle, and mature manufacturing and assembly processes; however, the acid resistance of metal light poles is poor. , the strength of the light pole is often reduced due to corrosion due to climate change and environmental factors; in order to solve the defects of corrosion resistance and low strength of the light pole, in recent years, glass fiber reinforced composite light Excellent properties such as high strength and acid corrosion resistance have gradually been recognized by the market; while the molding process of glass fiber reinforced composite light poles has to go through cumbersome process steps, especially in the curing system, it has to go through 2-3 or more rotation curing processes Therefore, the molding cycle of the glass fiber reinforced composite light pole is longer; secondly, due to the complexity of the rotary curing device, the amount of curing per unit time is limited, which eventually leads to low curing efficiency; thirdly, due to the molding of glass fiber reinforced composite The cost of raw materials such as glass fiber and resin used in material light poles is high, which makes the total cost 1-2 times higher than the total cost of metal light pole products; at the same time, glass fiber reinforced composite light poles have poor alkali resistance. It is easily corroded in an alkaline environment, and once the glass fiber reinforced composite light pole is corroded and damaged, its strength will be greatly reduced, resulting in the breakage of the light pole and even electrical failure; the existence of the above defects hinders the development of the composite material light pole.
