preparation example Construction

[0029] The present invention also discloses a preparation method of the ceramic tile adhesive described in the above technical solution, comprising the following steps:

[0030] After mixing 0.01-0.16 parts by weight of alcohol compound and 50-70 parts by weight of quartz sand, add 20-60 parts by weight of Portland cement, 1.5-5.5 parts by weight of redispersible rubber powder and 0.2-0.4 parts by weight of cellulose ether Mix well to get tile adhesive.

[0031] In the present invention, the selected raw materials include Portland cement, quartz sand, redispersible rubber powder, cellulose ether and alcohol compounds. The selection and use of materials for the raw materials will not be described in detail. Preferably, an accelerator is also included to accelerate the hydration speed of cement. In the present invention, there is no special limitation on the source of the accelerator, and commercially available products can be used. The dosage of the accelerator is preferably...

Embodiment 1

[0038] After mixing 0.05kg of stearyl alcohol and 62.45kg of quartz sand evenly, add 35kg of ordinary Portland cement with a hardness of 42.5, 2kg of redispersible rubber powder, 0.2kg of early strength agent and 0.3kg of hydroxypropylmethyl with a viscosity of 40,000 Mix the base cellulose ether evenly to obtain a tile adhesive.

[0039] The obtained tile adhesive and water were uniformly mixed according to the mass ratio of 100:23, and the performance of the tile adhesive was tested according to the provisions of the national building materials industry standard JC / T547-2005, and the results are shown in Table 1.

[0040] The resulting tile adhesive has an open time of up to 50 minutes.

Embodiment 2

[0041] Example 2 After mixing 0.05kg of stearyl alcohol and 62kg of quartz sand evenly, add 35kg of ordinary Portland cement with a hardness of 42.5R, 3kg of redispersible rubber powder, 0.15kg of early strength agent and 0.25kg of cement with a viscosity of 40000 and 45000 The hydroxypropyl methylcellulose ether (weight ratio: 1 / 1) is mixed evenly to obtain tile adhesive.

[0042] The resulting tile adhesive has an open time of up to 50 minutes.

Abstract

The invention provides a ceramic tile adhesive. The ceramic tile adhesive comprises the following components in parts by weight: 20-60 parts of Portland cement, 50-70 parts of quartz sand, 1.5-5.5 parts of re-dispersible gelatin powder, 0.2-0.4 part of cellulose ether and 0.01-0.16 part of an alcohol compound. According to the invention, hydroxyl in the alcohol compound is capable of forming a hydrogen bond with hydrone to take the effect of water retention, and the construction performance of the ceramic adhesive cannot be reduced; the alcohol compound is interacted with the cellulose ether, through the regulation of the proportion of the alcohols compound and the cellulose ether, the air-curing time of the ceramic tile adhesive is long, and the opening time is sufficient; therefore, the ceramic tile adhesive is suitable for adhering large ceramic tiles or lime ceramic tiles with low water absorption. Furthermore, the ceramic tile adhesive is firm in adhesion and free from hollowing and slippage.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to tile adhesives and a preparation method thereof. Background technique [0002] Ceramic tile is an important decorative material in the construction industry. It has rich colors and various patterns. It can not only play a beautifying effect, but also has functional advantages such as water resistance, hardness, hygiene, and easy cleaning. Therefore, it is more and more widely used in construction projects. [0003] At present, the development trend of tiles is polarized in size. Large tiles are more prominent in color, texture and decorative effect, and are becoming more and more popular in the decoration of large halls and halls and large residential buildings. Slender ceramic tiles save energy and have low transportation costs. They are suitable for decoration of small spaces such as kitchens and toilets. The above two types of tiles have high requirements on the drying time of the t...
