Problems solved by technology

However, the elongation of nylon exceeds 20%, so it cannot be used in the field of highway guardrails
The elongation rate of polyester industrial yarn is 13%-14%, which is relatively close to the technical index of road guardrails, but the disadvantages of the existing webbing technology cannot be reduced. The finished product of the webbing can maintain the original elongation rate of polyester industrial yarn, and it is difficult to weave a road with a thickness greater than 6.5mm. The required thickness of the guardrail

Embodiment Construction

[0008] The new type of highway guardrail webbing includes an original embryo webbing body made of polyester industrial yarn, and the original embryo webbing body is composed of more than one layer of original embryo webbing layers. In this embodiment, there are five layers. The original embryo webbing layer is formed by interlacing and pressing thousands of monofilaments in the transverse and longitudinal directions.

[0009] Wherein, the edge of the original embryo webbing belt is provided with a protective strip made of aluminum alloy; the left and right sides of the original embryo webbing belt body are respectively provided with two fixing holes that are open up and down, and the edges of the fixing holes A protective strip made of aluminum alloy is also provided. The highway guardrail webbing can be fixed to the guardrail on the roadside through the fixing hole. The thickness of the original webbing webbing body is greater than 6.5mm to meet the guardrail standard. The fence...

Abstract

The invention discloses a highway guardrail woven tape which comprises a blank woven tape body made of polyester industrial yarn. The blank woven tape body is formed by overlaying and combining one or more of blank woven tape layers, and the blank woven tape layers are formed by staggered pressing of several thousand horizontal and longitudinal monofilaments. By replacing an original highway guardrail made of metal with the highway guardrail woven tape, revolutionary flexible protection is achieved mainly according to safety performance of the highway guardrail, anti-crash performance of the guardrail and guiding performance of the guardrail and maximum dynamic deformation, the highway guardrail woven tape is reasonable in structure and low in production cost, and the whole production process is environmentally friendly and low in energy consumption.

Description

Technical field [0001] The invention relates to a new type of highway guardrail webbing. Background technique [0002] At present, the existing highway guardrails are all made of metal materials. Such highway guardrails have a long production time, high production costs, and require a large amount of metal materials, which causes a great waste of resources. The existing flexible highway guardrail webbing It is in a blank in the market, because highway guardrails require high strength and low extension (breaking elongation ≤ 10%). There are only two kinds of polyester industrial yarns and nylon yarns in the world for producing high-strength webbing materials. However, the elongation of nylon exceeds 20%, so it cannot be used in the field of highway guardrails. The elongation of polyester industrial yarn is 13%-14%, which is relatively close to the technical indicators of highway guardrails. However, the disadvantages of the existing webbing technology cannot reduce the finished ...
