example 1

[0016] Weigh 50g of zeolite into a crucible, place the crucible in a muffle furnace, heat up to 400°C at a heating rate of 5°C / min, keep calcined for 2 hours, and cool to room temperature after calcination to obtain activated zeolite, and put the activated zeolite into three wells. In the flask, vacuum the three-necked flask to a degree of vacuum of 20Pa, add 250mL mass fraction of 10% zinc acetate solution to the three-necked flask after vacuuming, stir and mix for 3min and continue to vacuum until the degree of vacuum in the three-necked flask is 20Pa, keep The vacuum was stopped after 10 minutes of vacuum, and then the three-necked flask was stirred for 30 minutes. After stirring, the three-necked flask was placed in an oven and aged at 40 ° C for 8 hours; after the above-mentioned aging, the mixture in the three-necked flask was filtered to obtain a filter residue Put the filter residue in a vacuum drying box to dry for 8 hours, put it in a crucible, place the crucible in a...

[0019]Weigh 570g of zeolite and put it into a crucible, place the crucible in a muffle furnace, raise the temperature to 450°C at a heating rate of 10°C / min, heat-preserve and roast for 4 hours, and cool to room temperature after roasting to obtain activated zeolite, put the activated zeolite into three In the flask, the three-necked flask was evacuated to a vacuum of 30Pa, and 300mL of mass fraction 10% zinc acetate solution was added to the three-necked flask after vacuuming, and after stirring and mixing for 5min, the vacuum was continued until the vacuum in the three-necked flask was 30Pa. Stop vacuuming after 20 minutes of vacuum, then stir and mix for 50 minutes. After stirring, put the three-necked flask into an oven and age at 45°C for 10 hours; after the above-mentioned aging, filter the mixed solution in the three-necked flask to obtain a filter residue. Put the filter residue in a vacuum drying oven to dry for 10 hours, then put it into a crucible, place the crucible...

[0022] Weigh 60g of zeolite into a crucible, place the crucible in a muffle furnace, raise the temperature to 425°C at a rate of 7°C / min, heat-preserve and roast for 3 hours, and cool to room temperature after roasting to obtain activated zeolite. Put the activated zeolite into three The three-necked flask was evacuated to a degree of vacuum of 25Pa, and 275mL of mass fraction 10% zinc acetate solution was added to the three-necked flask after the vacuum was evacuated. After stirring and mixing for 4min, the vacuum was continued until the degree of vacuum in the three-necked flask was 25Pa. Stop vacuuming after 15 minutes of vacuum, then stir and mix for 40 minutes. After stirring, put the three-necked flask into an oven and age at 43°C for 9 hours; after the above-mentioned aging, filter the mixture in the three-necked flask to obtain the filter residue. Put the filter residue in a vacuum drying oven to dry for 9 hours, then put it into a crucible, place the crucible in a muff...

Abstract

The invention discloses a preparation method of an antibacterial and anti-fouling white ceramic tile seam filling agent, belonging to the technical field of building materials. The preparation method comprises the steps of carrying out roasting activation on zeolite, then adding the activated zeolite into a zinc acetate solution, and carrying out high temperature decomposition to produce activated zeolite which is internally loaded with nano-zinc oxide; crushing quartz sand, then mixing the crushed quartz sand with deionized water, anhydrous ethanol and hydrochloric acid, firstly adding methyl dimethoxy silane into the mixture for carrying out hydrophobic modification, and then adding a silane coupling agent into the mixture so as to improve the water resistance of quartz powder; finally, mixing the materials such as modified quartz powder, white cement, the zeolite which is internally loaded with the nano-zinc oxide, and the like to obtain the antibacterial and anti-fouling white ceramic tile seam filling agent. The zeolite which is internally loaded with the nano-zinc oxide is added into the antibacterial and anti-fouling white ceramic tile seam filling agent, so that the ageing resistance and antibacterial property of the seam filling agent are improved; after surface modification is carried out on the quartz powder, the fouling resistance of the seam filling agent can be improved; the obtained seam filling agent is good in anti-mould effect, enables the surfaces of seams to be smooth and wear-resistant, is long in service life, and has lasting antibacterial property.

Description

technical field [0001] The invention discloses a preparation method of an antibacterial and stain-resistant white tile grout, belonging to the technical field of building materials. Background technique [0002] In modern buildings, ceramic tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. Reserve a certain gap, which requires tile caulk to fill. Caulking agent, also known as caulking agent and grout, is used to fill the joint material between tiles or natural stones attached to the wall or floor, and cooperates with decorative materials such as tiles and stones to provide beautiful Bonding, anti-seepage, etc. between the surface and the facing brick. The tile grout should have an expansion coefficient close to that of the tile and a certain flexibility, and can expand and contract with the tile to avoid cracks. The main components of tile caulking agent are cementitious material...
