Embodiment 1

[0025] At a temperature of 0°C and under stirring conditions of 100 r / min, add 40 parts by mass of methyl orthosilicate to 40 parts by mass of ethanol and stir for 10 minutes, then add 5 parts by mass of aqueous hydrochloric acid with a molar concentration of 2M in 20 times, Each interval is 20min, and then stirred for 10hr; under the stirring condition of 100r / min, add 40 mass parts of nano-silica sol and stir for 30min, and age at 25°C for 2 days; add 70 mass parts of the aged composite sol Continue to add 10 parts by mass of isopropanol to the nanometer floor hardener; after stirring for 30 minutes, add a hardening accelerator accounting for 3‰ of the mass ratio to the mixture, and stir for another 30 minutes to finally obtain a high hardness moisture-proof floor hardener .

[0026] The using method of this high hardness moisture-proof floor hardening agent is as follows (following embodiment and comparative example are all identical):

[0027] After polishing the self-lev...

Embodiment 2

[0029] At a temperature of 5°C, under stirring conditions of 100 r / min, 45 parts by mass of methyl orthosilicate was added to 40 parts by mass of ethanol and stirred for 10 minutes, and 7 parts by mass of aqueous hydrochloric acid with a molar concentration of 2M was added in 20 times. Each interval is 20min, and then stirred for 10hr; under the stirring condition of 200r / min, add 50 mass parts of nano-silica sol and stir for 30min, and age at 25°C for 2 days; add 60 mass parts of the aged composite sol Continue to add 10 parts by mass of isopropanol to the nanometer floor hardener; after stirring for 30 minutes, add a hardening accelerator accounting for 4‰ of the mass ratio to the mixture, and stir for another 30 minutes to finally obtain a high hardness moisture-proof floor hardener .

Embodiment 3

[0031] At a temperature of 10°C and under stirring conditions of 100 r / min, 50 parts by mass of methyl orthosilicate was added to 40 parts by mass of ethanol and stirred for 10 minutes, and 10 parts by mass of an aqueous hydrochloric acid solution with a molar concentration of 2M was added in 20 times. Each interval is 20min, and then stirred for 10hr; under the stirring condition of 150r / min, add 60 mass parts of nano-silica sol and stir for 30min, and age at 20°C for 2 days; add 50 mass parts of the aged composite sol Continue to add 10 parts by mass of isopropanol to the nanometer floor hardener; after stirring for 30 minutes, add a hardening accelerator accounting for 5‰ of its mass ratio to the mixture, and stir for another 30 minutes to finally obtain a high hardness moisture-proof floor hardener .

Abstract

The invention relates to the technical field of terraces, and aims to provide a preparation and use method of a high hardness moisture-proof terrace hardener. The preparation and use method includes the following steps that metasilicic acid methyl ester is added into ethyl alcohol under stirring, and stirring is conducted continuously; a hydrochloric acid water solution is added in 20 times, and stirring is conducted continuously after adding is completed; silicon oxide sol is added continuously, and aged for 2 days after stirring; aged composite sol and isopropanol are added into a nano terrace hardener, and stirred; and then a hardening accelerator is added, and stirred to obtain the high hardness moisture-proof terrace hardener. According to the preparation and use method of the high hardness moisture-proof terrace hardener, nano silicon oxide sol as a superhydrophilic material is added into the terrace hardener, a silicon oxide material as a superhydrophilic material has excellentstability, at the same time, hardness of a terrace can further be improved, and the terrace produces superhydrophilic performance so as to play a moisture-proof effect.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a method for preparing and using a high-hardness moisture-proof floor hardener. Background technique [0002] With the development of the economy and the improvement of people's living standards, the demand for high-quality large-scale floors in public places is increasing, and various functional floors have emerged as the times require. In seasons with high air humidity, such as Huangmeitian in the southern region, the floor will return to moisture, which not only affects the appearance, but also brings a lot of inconvenience in use. The currently used floor moisture-proof means are mainly achieved by adding a moisture-proof layer to the structural design of the floor. For example, the Chinese utility model patent CN201820484044.X achieves moisture-proof purpose by leaving holes in the middle layer to send air to the upper layer. CN201621354216.9 achieves the moisture-proof func...
