Natural colored water-permeable adhesive stone pavement material and preparation process thereof
The invention relates to the technical field of pavement materials, in particular to a natural colored water-permeable adhesive stone pavement material and a preparation process thereof. The natural colored water-permeable adhesive stone pavement material is prepared by mixing 80-90 parts of natural colored stone aggregate, 15-25 parts of cellulose, 3-8 parts of a cementing material and 5-10 parts of attapulgite filler, wherein the cellulose wraps the surface of the natural colored stone, the cementing material is prepared from 2-7 parts of modified polyol and 1-3 parts of an HDI curing agent, and the modified polyol is obtained by grafting 3, 3 '-dichlorodiphenyl disulfide to polyether polyol. According to the invention, disulfide bonds are introduced into the adhesive material, so that the self-repairing capability of the material is improved, rainwater is prevented from invading into the material to cause a corrosion phenomenon, abundant hydroxyl groups on cellulose and hydroxyl groups on the surface of the adhesive material generate hydrogen bond self-assembly, and the falling between the cementing material and aggregate is prevented.
本发明涉及路面材料技术领域，具体涉及一种天然彩色透水胶粘石路面材料及其制备工艺；所述一种天然彩色透水胶粘石路面材料，由80‑90份天然彩石骨料、15‑25份纤维素、3‑8份的胶结材料、5‑10份凹凸棒石填料混合制得；所述纤维素包裹在天然彩石表面，所述胶结材料由2‑7份改性多元醇和1‑3份HDI固化剂制得，所述改性多元醇是将3,3'‑二氯二苯二硫醚接枝到聚醚多元醇上得到；本发明在胶粘材料上引入二硫键，提高了材料的自修复能力，阻止了雨水侵入到材料内部造成腐蚀现象的发生，并且纤维素上丰富的羟基和胶粘材料表面的羟基产生氢键自组装，阻止胶结材料和骨料之间的脱落。
