Patent number: 11634556Abstract: A method for preparing an accelerator for sprayed mortar/concrete is provided. The accelerator includes an organic component, inorganic component aluminum sulfate, an initiator, and a reductant. The organic component in the form of a polymer monomer is added to concrete and polymerized into a polymer network structure in the presence of the initiator and the reductant; and the inorganic component aluminum sulfate promotes rapid hydration of the concrete to form an inorganic network structure. Such organic-inorganic interpenetrating network thickens a cement-based material rapidly to achieve strong adhesion, fast-setting and hardening properties and effectively reduces resilience of the sprayed mortar/concrete. The accelerator prepared by the method is well compatible with all sorts of cement, efficient and environmentally friendly.Type: GrantFiled: February 3, 2021Date of Patent: April 25, 2023Assignee: JIANGSU ARIT NEW MATERIALS CO., LTD.Inventors: Shanshan Qian, Ziming Wang, Suping Cui, Xiao Liu, Mingzhang Lan, Yali Wang

Patent number: 11117832Abstract: A fluorescent polycarboxylate superplasticizer and a preparation method thereof. The preparation process of the polycarboxylate superplasticizer is as follows. Firstly, a redox radical polymerization is performed on a monomer of an unsaturated acid and a derivative thereof, and an unsaturated polyether monomer to form a polycarboxylate superplasticizer pre-product. Then, the polycarboxylate superplasticizer pre-product is subjected to an esterification reaction with an organic molecule having a fluorescent property to obtain the fluorescent polycarboxylate superplasticizer. The method effectively reduces the reaction difficulty and makes the reaction rapid and efficient. The fluorescent polycarboxylate superplasticizer is non-toxic and non-polluting, and has good controllability in the production process and less side reactions.Type: GrantFiled: July 25, 2019Date of Patent: September 14, 2021Assignee: Jiangsu ARIT New Materials CO., LTD.Inventors: Shanshan Qian, Chunyang Zheng, Chunman Huang, Haidong Jiang, Yangcheng Hu, Wei Li, Jiezhong Gan
