Embodiment 1

[0029] The concrete surface curing protective agent in this embodiment is made of the following raw materials in weight percentage: nano-silica (5-10nm) 20wt.%, lithium silicate 20wt.%, acrylate emulsion (solid content 50%) 20wt.%, sodium methylsilicate 8wt.%, benzyl alcohol 1wt.%, and the rest are deionized water. Dissolve nano-silica, silicate, acrylate, hydrophobic agent and film-forming aid in deionized water, stir quickly to get a milky white liquid, which is concrete curing protective agent.

[0030] After using the above curing protection agent on the concrete surface, the ground performance test results are as follows (with the concrete test block without curing protection agent as a blank comparison):

[0032]

Embodiment 2

[0034] The concrete surface curing protective agent of this embodiment, in terms of weight percentage, is made of the following components: nano-silica (30-40nm) 28wt.%, sodium silicate 10wt.%, styrene-acrylate emulsion ( Solid content 50%) 32wt.%, siloxane 12wt.%, propylene glycol butyl ether 5wt.%, and the rest are deionized water. The preparation method is the same as in Example 1.

[0035] After using the above curing protection agent on the concrete surface, the ground performance test results are as follows (with the concrete test block without curing protection agent as a blank comparison):

Abstract

The invention relates to a concrete curing protective agent, which is prepared from the following components by weight percent: 20-30wt.% of nano-silica, 10-20wt.% of silicate, 20-35wt.% of acrylic ester, 8-15wt.% of a water repellent, 1-5wt.% of a film-forming assistant, and the balance water. The curing protective agent can improve the hardness and wear resistance of concrete ground, effectively solves the problems of concrete ground sugaring, dusting and the like, also can endow concrete with excellent waterproof and oil resistant properties, and can greatly improve the brightness of concrete ground without polishing.

Description

technical field [0001] The invention belongs to the field of building materials, and particularly relates to a curing protective agent applied to concrete floors. Background technique [0002] At present, concrete floors are widely used in shopping malls, docks, parking lots, logistics centers and 4S stores. However, during the long-term use of traditional concrete floors, there will be problems such as sanding, dusting, surface hardness and brightness reduction. [0003] The curing agent currently on the market can effectively solve the problems of sanding and dusting, but its brightness can only be reflected by polishing, and it does not have good waterproof and oil-resistant performance. [0004] The Chinese invention patent application with the application number of 201110152386.4 discloses an improved liquid concrete sealing and curing agent. It consists of the following components: 70-90wt% silicate, 0.05-0.2wt% penetrant, 0.3-0.5wt% surfactant, 0.4-0.6wt% surface mo...
