Problems solved by technology

[0003] At present, most of the anti-scouring concrete is prepared by high-standard cement, low water-binder ratio and adding reinforcing materials, which greatly improves the mechanical properties and anti-scouring strength of hardened concrete, but is not good for the volume stability of concrete. , the shrinkage and cracking problems of concrete with higher strength grades are more prominent in the practice of major projects

Abstract

The invention discloses a super-strong viscous polymer new material and a preparation technology thereof. The super-strong viscous polymer new material is obtained through the following steps: mixing 16-18 parts of an epoxy resin slurry, 2-4 parts of an active diluent, 6-8 parts of a solidification mixture and 70-80 parts of a base material, stirring and blending. Modified epoxy resin used in the invention is obtained through the following steps: taking 73.55wt% of epoxy resin E-44, 24.9wt% of Pluronic polyol polyether and 0.55wt% of benzyltriethylammonium chloride, adding the epoxy resin E-44 to a closed reactor, introducing an inert gas, heating to 85DEG C, adding a mixed solution prepared from Pluronic polyol polyether and benzyltriethylammonium chloride in a dropwise manner in a stirring state, heating to 125DEG C after the dropwise addition is finished, continuously reacting for 2.5h, and cooling. The super-strong viscous polymer new material has the advantages of excellent compression, impact, permeation and seawater corrosion resistance, no solvent, and reduction of pollution to environment.

Description

technical field [0001] The invention relates to the technical field of new materials, specifically, a new super-adhesive polymer material and a preparation process for a new super-adhesive polymer material. Background technique [0002] The dams of large reservoirs are often scoured by high-speed sandy currents. The erosion and cavitation damage of dam concrete by high-speed sandy water flow is a common and important problem in dam construction and operation. Improving the anti-abrasion and anti-cavitation ability of dam concrete is an important way to solve this problem . Due to the high water head and high dam body of large reservoirs, the flow rate of water in the discharge channel is very high, and the high-speed water flow entrains suspended and displaced matter, which is very harmful to the erosion damage of the overflow surface concrete. The concrete at the scoured parts of some large reservoir dams is severely worn due to the erosion of high-speed water shortly aft...
