Problems solved by technology

Its anti-penetration performance is far inferior to that of epoxy flooring. In some workshops where there are often oily stains, such as machining workshops, oily stains can easily penetrate into the floor, making it impossible to clean thoroughly.

preparation example Construction

[0090] A preparation method of a permeable floor hardener, comprising the following steps:

[0091] Step 1: adding lithium hydroxide and potassium hydroxide into the reactor, then adding deionized water, and stirring for 15 to 60 minutes to obtain a mixed alkali solution of lithium hydroxide and potassium hydroxide;

[0092] Step 2: Add methyl silicic acid and silicic acid to the mixed alkali solution of lithium hydroxide and potassium hydroxide obtained in step 1, heat, and stir for 60 to 120 minutes to obtain lithium silicate, potassium silicate, and methyl silicon A mixed solution of lithium acid and potassium methyl silicate;

[0093] Step 3: Add deionized water to the mixed solution obtained in Step 2, and stir for 10 to 50 minutes;

[0094] Step 4: Add a silane coupling agent to the solution obtained in Step 3, and stir for 15 to 60 minutes;

[0095] Step 5: Add siloxane polymer to the solution in Step 4, and stir for 90 to 150 minutes;

[0096] Step 6: adding a stabi...

Embodiment 1

[0115] Example 1: Add 500 grams of deionized water into the reactor, start stirring, weigh 40 grams of lithium hydroxide and 10 grams of potassium hydroxide, add them to the reactor in batches, and stir for 60 minutes to obtain a uniform and transparent alkali solution . Raise the temperature to 70°C, add 300 g of silicic acid and 100 g of methyl silicic acid, stir and react for 120 minutes to obtain a mixed solution of lithium silicate, potassium silicate, lithium methyl silicate and potassium methyl silicate. Then add 1000 grams of deionized water into the reactor, lower the temperature to 40 degrees Celsius, and drop 100 grams of silane coupling agent KH560 within 120 minutes. Ethoxysilane, after the dropwise addition, continue to keep warm for 30 minutes to obtain a uniform and transparent solution. Add 20 grams of stabilizer polyethylene glycol, 2 grams of surfactant alkyl alcohol polyoxyethylene ether sulfate, obtain the product of the present invention.

Embodiment 2

[0116] Example 2: Add 500 grams of deionized water into the reactor, start stirring, weigh 45 grams of lithium hydroxide and 5 grams of potassium hydroxide, add them to the reactor in batches, and stir for 60 minutes to obtain a uniform and transparent alkali solution . The temperature was raised to 70 degrees Celsius, 320 g of silicic acid and 80 g of methyl silicic acid were added, and the reaction was stirred for 120 minutes to obtain a mixed solution of lithium silicate, potassium silicate, lithium methyl silicate and potassium methyl silicate. Then add 1000 grams of deionized water into the reactor, lower the temperature to 40 degrees Celsius, add 100 grams of silane coupling agent γ-aminopropyltriethoxysilane dropwise within 120 minutes, and continue the heat preservation reaction for 30 minutes after the addition is completed. Then 30 g of polymethyltriethoxysilane was added dropwise, and after the dropwise addition was completed, the reaction was continued for 30 minut...

Abstract

The invention relates-the technical field of building materials, and especially relates-an osmotic floor hardener and a preparation method thereof. The osmotic floor hardener comprises, by weight, 500-3000 parts of deionized water, 10-70 parts of lithium hydroxide, 1-50 parts of potassium hydroxide, 200-500 parts of silicic acid, 50-300 parts of methanesiliconic acid, 50-300 parts of a silane coupling agent, 5-50 parts of a silane polymer, 1-40 parts of a stabilizer and 1-7 parts of a surfactant. The hardener can penetrate the internal of the floor, seal the capillary tubes of concrete, improve the surface compactness of the concrete and enhance the impermeability, the strength and the hardness of the concrete, so the floor is non-dusty, waterproof and is impermeable, the surface of the floor is easy to clean, and the hardness is improved; and polishing of the floor significantly improves the glossiness.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable floor hardener and a preparation method thereof. Background technique [0002] Although the concrete material has high strength, there are still some defects in the use of ordinary concrete. For example, the concrete floor is easy to generate dust, easy to wear, and its performance decreases sharply over time. Therefore, in industrial plants, parking lots, supermarkets, warehouses and other places that require frequent impact loads and require cleanliness, a layer of corundum high wear-resistant layer is generally poured on the concrete surface as a floor material during construction. [0003] Although the emery sand wear-resistant floor layer has higher strength than the concrete layer, it has good wear resistance, the surface strength (indentation diameter) is less than or equal to 3.3mm, and the compressive strength is above 80MPa (according to the natio...
