Fixed and integrated elastic height-limitation frame transverse beam material taking basalt fibers as framework

Abstract

The invention discloses a fixed and integrated elastic height-limitation frame transverse beam material taking basalt fibers as a framework, aiming at solving the problem that the rigidity of a height-limitation frame transverse beam is too great to cause serious traffic accidents. The invention provides the fixed and integrated elastic height-limitation frame transverse beam material taking butadiene styrene rubber as a binding agent and the basalt fibers as the framework. A transverse beam of a fixed and integrated elastic height-limitation frame is produced by basalt fiber cloth and the butadiene styrene rubber is used as the binding agent to prepare glue slurry, wherein the glue slurry is prepared from butadiene styrene rubber powder, benzoquinone dioxime, 2,2'-dithiodibenzothiazole, #120 gasoline and carbon black according to the mass ratio of 10 to 2 to 1 to 20 to 1. According to the fixed and integrated elastic height-limitation frame transverse beam material, the tensile strength of the height-limitation frame transverse beam material can be greater than 415MPa, the yield strength is greater than 254MPa, the elongation ratio is greater than 260 percent, the section shrinkage ratio is greater than 5 percent and the elastic modulus is not greater than 23GPa. The material provided by the invention can be used as the material for preparing the fixed and integrated height-limitation frame transverse beam.

Description

technical field [0001] The invention relates to a material for a fixed one-piece elastic limit-limited overhead beam with styrene-butadiene rubber as an adhesive and basalt fiber as a skeleton. Background technique [0002] It is very necessary to set up a fixed one-piece height-limiting bridge at the entrance of bridges, culverts, and tunnels. The use of the height-limiting bridge can not only remind passing vehicles of the upper limit height and intercept vehicles with excessive body height, but also prolong the service life of the road. At present, the fixed one-piece overhead beams in China are all steel plate structures, and are marked with upper limit height signs, but when the vehicle body is too high to brake in time or when the vehicle body jumps up due to road bumps during driving, it is inevitable. At this moment, the steel plate crossbeam of the height limit will "cut" the roof and cause serious traffic accidents, and the safety of the occupants in the car cannot...
