High-wear-resistance and high-toughness material, preparation method and environment-friendly wear-resistant anti-crack concrete
The invention relates to the technical field of modified rubber materials, in particular to a high-wear-resistance and high-toughness material, a preparation method and environment-friendly wear-resistant anti-crack concrete. The high-wear-resistance and high-toughness material is obtained by mixing liquid epoxy resin, an epoxy modified composite toughening material and a curing agent, in the preparation process, dicumyl peroxide is used as an initiator, allyl isocyanate is used as a grafting monomer, liquid ethylene propylene rubber is subjected to free radical grafting functionalization, isocyanate groups are introduced, and the high-wear-resistance and high-toughness material is obtained. Then primary amine on the amino-modified inorganic nanofiller and isocyanate groups are subjected to nucleophilic addition reaction, the inorganic nanofiller is connected to an ethylene propylene rubber molecular chain through stable chemical bonds, glycidyl further reacts with the isocyanate groups, epoxy groups are introduced, and the epoxy-modified composite toughening material is obtained. The introduction of the epoxy group can effectively improve the compatibility between the toughening material and the epoxy resin. By adding the high-wear-resistance and high-toughness material, the wear resistance and crack resistance of the concrete can be improved.
本发明涉及改性橡胶材料技术领域，具体涉及一种高耐磨高韧性材料、制备方法、环保耐磨抗裂混凝土。高耐磨高韧性材料包括液体环氧树脂与环氧改性复合增韧材料、固化剂混合得到，在制备过程中，以过氧化二异丙苯作为引发剂，以烯丙基异氰酸酯作为接枝单体，对液体乙丙橡胶进行自由基接枝官能化，引入异氰酸酯基团，再通过氨基改性无机纳米填料上的伯胺与异氰酸酯基团发生亲核加成反应将无机纳米填料以稳定的化学键连接到乙丙橡胶分子链上，缩水甘油进一步与异氰酸酯基团反应，引入环氧基团，得到环氧改性复合增韧材料，环氧基团的引入能够有效改善增韧材料与环氧树脂间的相容性。高耐磨高韧性材料的加入，能够提高混凝土的耐磨性能和抗裂性能。
