Reinforced compression-resistant anti-collision highway guardrail plate material
The invention relates to the technical field of composite materials, and discloses a reinforced compression-resistant anti-collision highway guardrail material. The material is prepared from the following raw materials in parts by weight: 15-30 parts of modified lignin fibers, 10-20 parts of carbon fibers, 6-20 parts of glass fibers, 40-60 parts of epoxy resin, 10-30 parts of foamed aluminum, 5-25 parts of foamed copper, 6-15 parts of foamed iron, 3-15 parts of silicon dioxide hollow microspheres, 2-16 parts of nitrile rubber buna powder and 0.2-2 parts of a coupling agent. The reinforced compression-resistant anti-collision highway guardrail material disclosed by the invention has the advantages of high hardness, good energy absorption effect, light weight, low manufacturing cost, high/low temperature resistance, oxidation resistance, good safety performance, good buffering and energy absorption effect and certain resilience characteristic, and avoids the defects that a traditional concrete guardrail is poor in buffering performance when collision occurs, a plastic guardrail is small in rigidity, small in elastic modulus and poor in oxidation resistance, a glass fiber reinforced plastic guardrail is poor in overall toughness and high in manufacturing cost, and a wave-shaped metal guardrail is prone to aging in daily use.
本发明涉及复合材料技术领域，并公开了一种增强抗压防撞公路护栏材料。采用以下重量份的原料制成：改性木质素纤维15‑30份，碳纤维10‑20份，玻璃纤维6‑20份，环氧树脂40‑60份，泡沫铝10‑30份，泡沫铜5‑25份，泡沫铁6‑15份，二氧化硅空心微珠3‑15份，丁晴橡胶粉2‑16份，偶联剂0.2‑2份。本发明所公开的一种增强抗压防撞公路护栏材料具有硬度大，吸能效果好，质量轻，造价低，耐高/低温，抗氧化，安全性能良好，缓冲吸能效果良好，具有一定的回弹特性的优点，避免了传统的混凝土护栏在发生碰撞时缓冲性能差，塑料护栏的刚度小，弹性模量小，抗氧化性能差，玻璃钢护栏的整体韧性较差，造价高和波形金属护栏在日常使用中易老化的缺点。
