Description

TECHNICAL FIELD [0001] The present invention relates to a composition for a tile adhesive and a joint material having improved strength and durability, and a tile construction method for a concrete structure using the tile adhesive composition and the tile adhesive composition.

The present invention relates to a composition for a tile adhesive and a jointing material having improved strength and durability and a method for constructing a concrete structure using the same. More particularly, the present invention relates to a tile adhesive composition for a tile, The tile of the concrete structure under the harsh environment of the water purification plant, the reservoir, the underground and the exponential structure is excellent in the water, the chlorine ion, the chemical erosion and the waterproofing property because of the excellent salt resistance, acid resistance, abrasion resistance, fire resistance and durability, A tile adhesive and a composition for a jointing material which can reduce the maintenance cost of a concrete structure and can improve the salt resistance and durability of the concrete structure and a tile construction method using the same .

  In general, tile adhesives are used for bonding tiles to be applied as interior and exterior materials in the finishing process of buildings. Tiles are ceramic tiles, which are often called ceramic tiles, porcelain tiles made by baking glaze at high temperature, Can be categorized into a high-temperature and high-pressure firing tile with excellent design, color and gloss, and they have different water absorption rates.

The prior art tile adhesives include cement systems incorporating cement, aqueous acrylic resins whose main component is an acrylic liquid resin, and epoxy resins obtained by mixing an epoxy resin and a polyamine.

Epoxy tile adhesives are widely used as general tile adhesives. These epoxy-based tile adhesives have problems of low adhesive strength due to high temperature and high humidity at the time of using adhesive under high temperature and high humidity such as summer rainy season. Especially, in the case of low humidity and temperature during winter, Time has elapsed. In order to improve this, there was a method in which a separate curing accelerator including a tin catalyst was added to the curing catalyst in a short period of time in order to improve it. However, since the catalyst must be added to the adhesive every time the adhesive is used, .

On the other hand, since the tile adhesive is made from the dough after the size of the tile is enlarged, the time available for adhering is drastically shortened, resulting in a decrease in work efficiency and shortening of the adhering time. In addition, as the building becomes super-tall, many large tiles are built on the inner gypsum board surface. Since the amount of adhesive is over 10kg / ㎡ in order to align the horizontal surface of the tile due to warping of the ground surface and construction of large tile, And the strength of the gypsum board surface is weakened by the weight of the large tile, so that there is a great risk that the gypsum board surface is destroyed. Accordingly, there is a great need for development of adhesives having a lighter weight and a longer sticking time in the tile adhesive market.

If the water absorption rate is high, impurities or water penetrate into the concrete, which may increase the porosity inside the concrete, which may cause the damage of the structure.

division Example 1 Example 2 Example 3 Comparative Example 1 Absorption Rate (%) 0.05 0.03 0.01 0.07

As shown in Table 9 above, the composition for tile adhesive and jointing material prepared according to Examples 1 to 3 had a lower water absorption than the composition prepared according to Comparative Example 1.

&Lt; Test Example 10 &

The composition for tile adhesive and jointing material prepared according to Examples 1 to 3 and the polymeric mortar composition prepared according to Comparative Example 1 were applied to the concrete base plate 300 mm x 300 mm x 60 mm on the surface of the water treatment facilities. The temperature of the test room is 20 ± 2 ° C. After the test piece is left to stand for 1 hour or more, a spherical weight (steel spheres of 500g ± 2) is dropped onto the waterproof layer of the specimen from a position 0.5m . The weights were dropped at the height of 0.5m, 1m, and 1.5m, respectively, to observe surface damage. The results are shown in Table 10 below.

As shown in Table 10 above, it was found that the compositions prepared according to Examples 1 to 3 and the compositions for tile adhesive and jointing material according to Comparative Example 1 were excellent in impact resistance.

&Lt; Test Example 11 &

The compositions for tile adhesive and jointing material prepared according to Examples 1 to 3 and the polymeric mortar composition prepared according to Comparative Example 1 were coated with a composition of 120 mm x 60 mm in the middle of a 200 mm x 80 mm CRC board. After the specimens were cured for a certain period of time, they were allowed to stand for 24 hours. After the specimens were subjected to a behavior of 2,000 times at a temperature of -10 ° C at a moving speed of 5 times / min and a behavior width of 0.5 to 2.5 mm, (Piercing, tearing, fracture, etc.) were observed. The results are shown in Table 11 below.
