example 1

[0025] Mix chitosan and 12% acetic acid solution in a beaker at a mass ratio of 1:50, move the beaker into a digital speed-measuring constant-temperature magnetic stirrer, at a temperature of 36°C and a rotational speed of 280r / min. After stirring and mixing for 40 minutes, add polyvinyl alcohol 4 times the mass of chitosan to the beaker. Stir and dissolve at a temperature of 85°C and a rotation speed of 300r / min for 3 hours, and then add chitosan with a mass of 0.6 to the beaker. Glutaraldehyde, at a temperature of 60℃ and a rotation speed of 320r / min, stir and react for 2h to obtain a mixed treatment solution. The mixed treatment solution is transferred to a vacuum drying oven and dried in a vacuum at a temperature of 50°C. 6h, get chitosan-polyvinyl alcohol hydrogel; mix chitosan-polyvinyl alcohol hydrogel with saturated sodium carbonate solution at a mass ratio of 1:15, soak for 4 days at room temperature, and filter to obtain Pretreat the hydrogel; mix the protein and phos...

[0027] Mix the protein and pH 7.4 phosphate buffer in a flask with a mass ratio of 1:15, and add protease with 0.06 times the mass of the protein to the flask, and then move the flask into a digital speed-measuring thermostatic magnetic stirrer at a temperature of 38°C , Under the condition of rotating speed of 360r / min, constant temperature stirring reaction for 40min to obtain the degraded protein mixture; the natural zeolite is crushed in a crusher and passed through a 160-mesh sieve to obtain crushed zeolite. The crushed zeolite is at a temperature of 280°C, The pretreated zeolite is obtained by the heat preservation treatment for 70 minutes. The pretreated zeolite and the degraded protein mixture are mixed at a mass ratio of 1:25, stirred and mixed for 120 minutes at a speed of 280r / min and room temperature, and filtered to obtain a modified zeolite; Graphite and oxidant are mixed in a beaker according to a mass ratio of 1:8, and the beaker is moved into a digital speed-mea...

Abstract

The invention discloses a method for preparing tile grout, and belongs to the technical field of construction materials. The method comprises the following steps: mixing chitosan-polyvinyl alcohol hydrogel and saturated sodium carbonate solution, and filtering to obtain pre-treated hydrogel; stirring and mixing pretreated zeolite and degraded protease, and filtering to obtain modified zeolite; mixing graphite and oxidant, stirring to react, concentrating by rotary evaporation to obtain oxidized graphite; sequentially weighing the following components in parts by mass: 30-40 parts of cement, 50-60 parts of quartz sands, 2-6 parts of pigment, 8-12 parts of pretreated hydrogel, 12-15 parts of modified zeolite and 6-10 parts of oxidized graphite; and stirring and mixing the raw materials, adding water which is 0.6-0.8 times mass of the cement, continuously stirring, and discharging to obtain the tile grout. The tile grout has excellent mechanical performance, and the phenomenon of efflorescence can be reduced.

Description

Technical field [0001] The invention discloses a preparation method of a ceramic tile joint sealant, which belongs to the technical field of building materials. Background technique [0002] Ceramic tiles are widely used in the field of construction because of their beautiful appearance, hardness and solidity. Tile grout is used as a supporting material for tile paste, and it increases with the increase in the use area of ​​tiles. With the improvement of people's living standards and awareness, tile grouts have developed from the initial white cement to the current mainstream polymer-modified cement-based grouts. [0003] The caulking agent is mainly used in the exterior wall tile finishing system, and its quality directly affects the exterior wall decoration effect. At present, there are often quality problems such as cracking, weak bonding, efflorescence, and poor mechanical properties after the use of joint sealants in the market. Among them, efflorescence is the most common a...
