The invention discloses heat insulation and heat preservation concrete and a preparation method thereof.The heat insulation and heat preservation concrete is prepared from, by weight, 150-200 parts of cement, 200-250 parts of coarse aggregate, 300-420 parts of fine aggregate, 120-200 parts of lightweight aggregate and 50-90 parts of water, modified polyurethane microbeads are adopted as the lightweight aggregate, and the modified polyurethane microbeads are adopted as the fine aggregate. The modified polyurethane microbeads are obtained by growing a metal organic framework on the surfaces of polyurethane microbeads. A building prepared from the concrete can keep good heat insulation performance and mechanical performance within a long time, the indoor environment is warm in winter and cool in summer, and the building is suitable for working and living. 本申请公开了一种隔热保温混凝土及其制备方法，隔热保温混凝土按照重量份计，包括如下组分：150-200份水泥、200-250份粗骨料、300-420份细骨料、120-200份轻骨料、50-90份水，其中，轻骨料采用改性聚氨酯微珠，改性聚氨酯微珠采用聚氨酯微珠表面生长金属有机框架得到。本申请混凝土制备的建筑，在较长的时间
