Abstract
The invention relates to a highway guardrail of stretching resin composite which is characterized by comprising mesh pattern duplex typed fortifying fibers and resin polymer plastic and accessory ingredient and the main components are as follows according to the parts by weight: the mixed resin using the unsaturated vibrin is 100, parting agent is 1 to 10, the modified engineering plastics are 5 to 50, the firming agent is 0.5 to 7, the glass cenospheres are 5 to 20, the resin acceptor is 1 to 10, the fluorescent powder is 1 to 20, the fiber glass rovings are 40 to 80, the glass fiber crude is 20 to 40, the glass fiber crude blanket is 10 to 20, the carbon fiber is 1 to 15 and the aging resistant is 1 to 10. The highway guardrail of stretching resin composite has the beneficial effects that: after high temperature and high pressure and the adopting of the mixed resin, the chemical reaction is produced and the molecular structure of the original resin is changed. A cross-linked network shaped is formed, therefore the strength and rigidity of the resin are improved and the resin has good toughness. The performance of the highway guardrail of stretching resin composite is in accordance with the standards of the JT/T281-2007 and JTGD81-20066 and can be exchanged with the steel guardrail. At the same time, the highway guardrail of stretching resin composite has the beneficial effects of good strength, being not east to deform, abrasive resistance, shocks absorbing, noise muting, erosion resisting, fluorescence and reflection.
