Flame-retardant elastic material for bridge expansion joints as well as preparation method and application of flame-retardant elastic material
The invention provides a flame-retardant elastic material for a bridge expansion joint as well as a preparation method and application of the flame-retardant elastic material. The preparation method of the flame-retardant elastic material for the bridge expansion joint comprises the step of mixing and reacting the phosphorus and nitrogen functionalized lignin nanoparticles and a prepolymer to obtain the flame-retardant elastic material for the bridge expansion joint. The flame-retardant elastic material for the bridge expansion joint prepared by the preparation method has excellent flame retardance while meeting the use requirements of the bridge expansion joint, solves the problems that the elongation and tensile strength of a high-molecular elastic material are reduced due to the addition of a flame retardant and the fireproof grade of an elastomer filled seamless expansion joint is low, and is suitable for large-scale popularization and application. The method is suitable for elastomer filling type seamless expansion joints of various structural forms.
本申请提供一种桥梁伸缩缝用阻燃弹性材料及其制备方法和应用。该桥梁伸缩缝用阻燃弹性材料的制备方法包括将磷、氮功能化的木质素纳米颗粒与预聚体混合反应得到桥梁伸缩缝用阻燃弹性材料的步骤。通过该制备方法制备的桥梁伸缩缝用阻燃弹性材料在满足桥梁伸缩缝使用要求的同时，具有优异的阻燃性能，解决了高分子弹性材料因添加阻燃剂造成的伸长率和拉伸强度降低、以及弹性体填充式无缝伸缩缝的防火等级低的问题，适用于各种结构形式的弹性体填充式无缝伸缩缝。
