Problems solved by technology

[0003] Although steel anti-glare panels are reliable in strength, they are heavy and costly. Although plastic anti-glare panels are light in weight, they are easy to break under the action of external forces such as strong winds and have a short service life.

Embodiment 1

[0023] Highway construction temporarily uses flexible anti-glare plates

[0024] The anti-glare plate is made of weight, from the following raw materials: ethylene-vinyl acetate copolymer 99, EPDM 0.2, natural rubber 0.45, zinc chloride 0.15, color mother 0.2, anti-ultraviolet modified agent 0.01, UV resistance Take 2,4-dihydroxybenzophenone; specific preparation method includes the following steps:

[0025] (1) At 260 ° C, the ethylene-vinyl acetate copolymer was plasticized to give a plastic ethylene-vinyl acetate copolymer, and then added to the plasticized ethylene-vinyl acetate copolymer. Mix is ​​uniform, then add EPDM, mix uniform, and finally add natural rubber, zinc chloride and anti-ultraviolet modified agents, mix well, and premixed;

[0026] (2) In the forming mold of the premix into the EVA foamed molding apparatus, the pressure between the inner mold and the outer mold of the molding die is 2.6 MPa, and the formation of the molded embryo is formed under 175 ° C, and ...

Abstract

The invention discloses a flexible anti-glare board temporarily used for road construction, which comprises the following raw materials in parts by weight: ethylene-vinyl acetate copolymer 98.5-99.5, EPDM 0.15-0.25, natural rubber 0.4-0.5, zinc chloride 0.13-0.17 , UV modifier 0.01~0.02, color masterbatch 0.15~0.25. The anti-glare board of the present invention is light in weight, low in cost, easy to form, green and environmentally friendly, has very good elasticity and deformation recovery rate, is not easy to break, has a long service life, has very good aging resistance, and the product also has good tensile strength. Tensile strength and rolling strength, low temperature resistance, high temperature resistance, rolling resistance, bending resistance, wind resistance, immersion resistance, can ensure the outdoor use conditions, as a road safety protection facility, used for new construction, reconstruction and expansion of road construction , Good anti-break performance.

Description

Technical field [0001] The present invention relates to road facilities, and in particular to a highway construction temporary flexible anti-glare plate. Background technique [0002] The anti-glare board is a traffic safety product for the installation of the central partition of the highway to the highway in the central partition of the highway to the highway. Multi-set in the middle of the highway, on the middle of the fence or the guardrail, there are also some settings on the central opening activity guardrail, from the material, steel anti-glare board, plastic anti-glare board, etc. [0003] Although the steel anti-glare plate is reliable, the quality is heavy, the cost is high, and the plastic anti-glare board is light, but the external force such as strong wind is easy to break, the service life is short. Inventive content [0004] The technical problem to be solved by the present invention is to provide a highly light, highly elasticity and deformation recovery rate, te...
