AI Technical Summary

Technical Problem

Existing epoxy resin concrete has shortcomings in flame retardancy and aging resistance, is prone to decomposition and combustion, and has a low utilization rate of solid waste.

Method used

Using modified waterborne epoxy resin, composite boron nitride nanosheets, and solid waste as raw materials, composite boron nitride nanosheets were prepared by ball milling. Modified waterborne epoxy resin was then introduced to prepare high-strength epoxy resin concrete. Steel slag was used as coarse aggregate, and fly ash and granite powder were used as fine aggregate to form a complex cross-linked network.

Benefits of technology

It improves the weather resistance, flame retardancy, and strength of epoxy resin concrete, realizes the resource utilization of solid waste, and has significant engineering and economic value.

Abstract

本发明涉及混凝土技术领域,具体是一种高强度环氧树脂混凝土的制备方法及其应用,利用钢渣作为粗骨料,以矿物掺合料粉煤灰、炉渣、花岗岩石粉共混作为细骨料,以复合氮化硼纳米片为改性剂,引入改性水性环氧树脂,制备得到环氧树脂混凝土;采用三乙烯四胺与4,4'‑二氨基二环己基甲烷复配作为固化剂;通过球磨法得到羟基化氮化硼纳米片,然后以六亚甲基二异氰酸酯三聚体为交联剂,以羟基封端的含硅聚磷酸酯阻燃剂为功能组分,制备得到复合氮化硼纳米片为改性剂;将环氧树脂预聚体与聚氨酯预聚体混合,以哌嗪作为扩链剂,采用化学共聚法制备改性水性环氧树脂。
