Flexible guardrail and rubber sponge body composition and production technology applied to flexible guardrail

Abstract

The invention relates to a flexible guardrail and a rubber sponge body composition and production technology applied to the flexible guardrail. The flexible guardrail is characterized by comprising acolumn, a PVC sleeve which is dynamically matched with the column sleeves the outer wall of the column, and the outer wall of the PVC sleeve is wrapped by a rubber sponge body; the rubber sponge bodyis statically matched with the outer wall of the PVC sleeve, and an air flow guide device is arranged in the rubber sponge body. The rubber sponge body composition is characterized in that the rubbersponge body is prepared from rubber, padding, zinc oxide, stearic acid, softener, an anti-aging agent, sulfur, an accelerant, an ultraviolet-proof special addition agent and a foaming agent; the production technology of the rubber sponge body comprises the steps of material mixing, material extrusion, forming at the initial stage, processing at the middle stage and assembly at the later stage; theflexible guardrail has the advantages that the flexible guardrail is high in impact absorption capacity and good in impact stress dispersion and buffer effect, and the driving direction can be automatically restored.

Description

technical field [0001] The invention relates to the technical field of traffic safety equipment, in particular to a technical formula of a flexible guardrail and a rubber sponge and its manufacturing technology. Background technique [0002] Highway guardrail refers to a safety facility installed on both sides of the road. When an out-of-control vehicle hits the guardrail, the deformation of the guardrail itself can guide the running track of the out-of-control vehicle safely, thereby preventing the out-of-control The vehicle goes out of the road or rushes into the opposite lane; however, the existing guardrail has poor ability to absorb the impact force, and is subjected to the reverse force of the guardrail during the collision, which will easily cause the car to overturn, turn, go backwards, and even Cause secondary traffic accident to take place, increased degree of harm. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of th...
