Problems solved by technology

Water barriers need to be filled with water one by one during the operation process. The construction efficiency is low. The length of each water barrier is about 1 meter. The long-distance road sealing requires a lot of traffic, inconvenient transportation, and poor durability. Basically, it can only be used once. , the product strength is poor, the collision is easy to deform, and the material is easy to age and corrode; the safety of the closed road with road cones is poor, and the road cones are easily blown down in windy weather or when heavy vehicles pass by, so the construction safety is not guaranteed

Embodiment Construction

[0011] The following examples can enable those skilled in the art to understand the present application more comprehensively, but do not limit the present application in any way. Unless otherwise stated, the percentages in this application refer to mass percentages.

[0012] The temporary protective guardrail board of the present application is made of a composite material with polyester resin as the main material. Specifically, the composite material includes 30% of resin (Lukai 404), 45% of yarn (Jushi alkali-free 4800), calcium powder 10%, color paste (6024) 3%, glyceryl neodecanoate 0.3%, tert-butyl ester 0.3%, non-alkali felt 11.4%. Resin is added to form the frame of the guardrail; yarn and calcium powder are used to enhance the structural strength, and the guardrail cannot reach the anti-collision strength without this material; the color paste is used to color the guardrail to achieve the required corresponding color; add new capric acid glycerin Ester and tert-butyl ...

Abstract

The invention provides a protective guard. The protective guard comprises an anti-collision barrel and a guardrail plate connected with the anti-collision barrel through bolts, wherein the guardrail plate is prepared from the following materials in percentage by mass: 30% of resin, 45% of yarns, 10% of a calcium powder, 3% of color paste, 0.3% of mold-releasing oil, 0.3% of tert-butyl ester and 11.4% of alkali-free felt. The guardrail plate of the protective guard is high in strength, low in deformation rate, high in thermal deformation temperature and high in corrosion resistance. Besides, the protective guard adopts a new structural connection mode, and compared with a traditional protective device, the protective guard is more convenient to install, high in safety and more attractive.

Description

technical field [0001] The present application relates to the field of materials, in particular, to guardrails. Background technique [0002] For road occupation construction operations, in order to ensure the safety of the operation, the construction must be carried out by temporarily closing the corresponding lanes. The traditional temporary closing methods are generally water barriers and road cones. Water barriers need to be filled with water one by one during the operation process. The construction efficiency is low. The length of each water barrier is about 1 meter. The long-distance road sealing requires a lot of traffic, inconvenient transportation, and poor durability. Basically, it can only be used once. , The strength of the product is poor, the collision is easy to deform, and the material is easy to age and corrode; the safety of the closed road with road cones is poor, and the road cones are easily blown down in windy weather or when heavy vehicles pass by, so ...
