Embodiment 1

[0042] This application discloses a benzene-free tile cement, which includes the following raw materials: cement, silt, hydroxypropyl methylcellulose, starch ether, latex powder, instant rubber powder, resin glue, early strength agent triethanolamine, and water reducer .

[0043] The preparation method of the water reducer is as follows: firstly, at 85°C, mix polycarboxylate and deionized water, stir and add calcium lignosulfonate dropwise at a rate of 1 drop / s, and stir at constant temperature for 1 hour; then add oil The product of butyl ester and pentaerythritol oleate was stirred at 50°C for 20 minutes. After stirring for 10 minutes, continue to add n-butyl borate neopentyl glycol and stir for 5 minutes. Finally, add polyvinyl alcohol and stannous octoate, and stir at constant temperature for 1 hour. , cooled to room temperature to obtain a water reducer.

[0044] The content of each component is shown in Table 1 below.

Embodiment 2

[0046] This application discloses a benzene-free tile cement, which includes the following raw materials: cement, silt, hydroxypropyl methylcellulose, starch ether, latex powder, instant rubber powder, resin glue, early strength agent triethanolamine, and water reducer .

[0047] The preparation method of the water reducer is as follows: firstly, at 90°C, mix polycarboxylate and deionized water, stir and add calcium lignosulfonate dropwise at a rate of 1 drop / s, and stir at constant temperature for 2 hours; then add oil The product of butyl ester and pentaerythritol oleate was stirred at 60°C for 30 minutes. After stirring for 15 minutes, continue to add n-butyl borate neopentyl glycol ester and stir for 8 minutes. Finally, add polyvinyl alcohol and stannous octoate, and stir at constant temperature for 2 hours. , cooled to room temperature to obtain a water reducer.

[0048] The content of each component is shown in Table 1 below.

Embodiment 3

[0050] This application discloses a benzene-free tile cement, which includes the following raw materials: cement, silt, hydroxypropyl methylcellulose, starch ether, latex powder, instant rubber powder, resin glue, early strength agent triethanolamine, and water reducer .

[0051] The preparation method of the water reducer is as follows: firstly, at 88°C, mix polycarboxylate and deionized water, stir and add calcium lignosulfonate dropwise at a rate of 1 drop / s, and stir at constant temperature for 2 hours; then add oil Butyl butyl borate and pentaerythritol oleate were stirred at 55°C for 25 minutes. After stirring for 12 minutes, continue to add n-butyl borate neopentyl glycol and stir for 7 minutes. Finally, add polyvinyl alcohol and stannous octoate, and stir at constant temperature for 1 hour. , cooled to room temperature to obtain a water reducer.

[0052] The content of each component is shown in Table 1 below.

Abstract

The invention relates to the field of building materials, and discloses benzene-free ceramic tile mortar which comprises the following raw materials in parts by weight: 20-40 parts of cement; 60-80 parts of silt; 0.1-0.5 part of hydroxypropyl methyl cellulose; 0.1-0.5 part of starch ether; 0.1-0.6 part of latex powder; 0.1-0.6 part of instant glue powder; 0.1-0.6 part of a resin adhesive; 0.1-0.6part of an early strength agent; and a water reducing agent. The invention has the following advantages and effects: polycarboxylate molecules are directionally adsorbed on the surfaces of cement particles, so that the surfaces of the cement particles are negatively charged to form an electrostatic repulsion effect, and calcium lignosulphonate and polycarboxylate are mixed to further promote mutual dispersion of the cement particles, destroy a flocculation structure and release part of wrapped water to participate in flowing; and therefore, the flowability of the ceramic tile mortar is effectively improved, and the bonding performance is improved.

Description

technical field [0001] The present application relates to the field of building materials, in particular to a benzene-free tile cement. Background technique [0002] Tile cement, also known as ceramic tile adhesive, is mainly used to paste decorative materials such as ceramic tiles, face bricks, and floor tiles, so this product is also very suitable for decoration of interior and exterior walls, floors, bathrooms, kitchens and other buildings. places; with high temperature resistance, good flexibility, waterproof, impermeability, crack resistance, anti-aging performance. [0003] However, some current tile mastics cannot fully fill the gaps when laying tiles due to poor fluidity, and the application performance is not good, which easily affects the laying effect of tiles, so there is still room for improvement. Contents of the invention [0004] In order to improve the fluidity of the tile mastic and improve the tile laying effect, the present application provides a benze...
