NOVELTY - High flexural modulus imitation cement preparation technology involves compression molding 30-50 pts. wt. limestone, 5-10 pts. wt. clay, 10-15 pts. wt. silicon micropowder, 30-60 pts. wt. modified resin, and 6-12 pts. wt. enhancement solution. The modified resin is obtained using pyromellitic dianhydride, 4,4'-diaminodiphenyl sulfone, N,N-dimethylformamide, paraformaldehyde, p-aminophenol, N,N-dimethylformamide, chlorobenzene, 2,2-diphenylpropane, dibenzoyl peroxide, triethanolamine, xylene, sodium carbonate aqueous solution, hexadecanoic acid, ether, copper sulfate, tin powder, concentrated hydrochloric acid, Epoxy resin E-51 (RTM: diglycidyl ether of bisphenol A), N,N-dimethylformamide, and dibutyltin dilaurate. USE - High flexural modulus imitation cement preparation technology. ADVANTAGE - The method involves preparation of high flexural modulus imitation cement with excellent durability, antioxidant capacity, heat-resistance, mechanical properties, and bending grinding capacity. DETAILED DESCRIPTION - High flexural modulus imitation cement preparation technology involves compression molding 30-50 pts. wt. limestone, 5-10 pts. wt. clay, 10-15 pts. wt. silicon micropowder, 30-60 pts. wt. modified resin, and 6-12 pts. wt. enhancement solution. The modified resin is obtained by mixing pyromellitic dianhydride, 4,4'-diaminodiphenyl sulfone, and N,N-dimethylformamide, raising the temperature to react to obtain intermediate 1, mixing intermediate 1, paraformaldehyde, p-aminophenol and N,N-dimethylformamide, reacting uniformly, adjusting the pH value of the reaction solution to be neutral to obtain intermediate 2, adding chlorobenzene to the reaction kettle, stirring, introducing phosgene into the intermediate 2 and reacting to obtain intermediate 3, adding 2,2-diphenylpropane into the reaction kettle, stirring and dripping mixed acid, raising the temperature to prepare intermediate 4, and mixing intermediate 4, dibenzoyl peroxide and triethanolamine, raising the temperature, introducing chlorine gas to carry out the reaction to prepare intermediate 5, dissolving intermediate 5 in xylene, adding sodium carbonate aqueous solution, and reacting to prepare intermediate 6, mixing intermediate 6, hexadecanoic acid, ether, and copper sulfate and refluxing, adding tin powder and concentrated hydrochloric acid to react, adjusting the pH value of the reaction solution to obtain intermediate 7, adding Epoxy resin E-51 (RTM: diglycidyl ether of bisphenol A), and N,N-dimethylformamide to intermediate 7 in the reaction kettle, raising the temperature to continue the reaction, adding intermediate 3, and after the reaction is continued, dripping dibutyltin dilaurate, and reacting.
