Abstract

The invention discloses a non-toxic and non-corrosiveness nanosilicone dioxide enhanced type concrete curing agent, and relates to the technical field of concrete curing. The non-toxic and non-corrosiveness nanosilicone dioxide enhanced type concrete curing agent is prepared from, by weight, 5-8 parts of nanosilicone dioxide, 70-80 parts of acrylic resin, 25-30 parts of modified montmorillonoid, 20-25 parts of furnace ash and slag, 15-20 parts of konjac powder, 12-15 parts of sulfonated melamine, 10-13 parts of polyether modified silicone, 10-13 parts of palmitic acid, 8-12 parts of hydrogenated castor oil, 7-10 parts of surface active agents, 5-8 parts of rice bran wax, 30-35 parts of butyl acrylate and 200-250 parts of water. By means of the curing agent, excessive water inside concrete can be effectively prevented from evaporating too early, the curing aim is achieved, construction operation is convenient, and the non-toxic and non-corrosiveness nanosilicone dioxide enhanced type concrete curing agent is free of toxin and corrosiveness and has no adverse effect on human bodies or the environment.

Description

[0001] Technical field: [0002] The invention relates to the technical field of concrete maintenance, in particular to a non-toxic and non-corrosive nano silicon dioxide reinforced concrete maintenance agent. [0003] Background technique: [0004] Because there are a large number of capillary channels in concrete and mortar, water is easy to lose after passing through a high temperature environment. At the same time, the evaporation of water and the absorption of water at the base will also quickly disperse the water in concrete and mortar. Therefore, it is necessary to ensure the water content of concrete and mortar. The chemical process requires moisturizing and maintenance. [0005] The traditional maintenance methods include grass bag maintenance, plastic film maintenance and watering maintenance, but these methods are time-consuming, labor-intensive and seriously waste water resources. The method of using film-forming curing agent to maintain concrete has a long history...
