Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a renovation material for bulging and warping tiles, and a preparation method and application thereof. Background Art

[0002] As people's living standards improve, the demand for home decoration is getting higher and higher. In decoration, floor tiles are one of the indispensable decorative materials. However, sometimes we will find that after using tiles for a period of time, the tiles will be arched.

[0003] There are usually the following reasons for the bulging and warping of tiles: 1. Thermal expansion and contraction of tiles: During long-term use, tiles will be affected by temperature and produce thermal expansion and contraction. If sufficient expansion gaps are not reserved when laying tiles, or the gaps are blocked by fillers, the tiles cannot release stress when expanding, which will cause arching. 2. Improper construction: During construction, if the ratio of cement to yellow sand is incorrect, such as low cement grade and too much yellow sand, the cement layer will not have enough adhesion, which will cause the tiles to warp. 3. Improper ground foundation treatment, such as the ground is too smooth and not roughened, will also affect the adhesion between the tiles and the cement layer. 4. Improper material selection or use: The quality of the tile glue used is not up to standard, or after the tiles are laid, if they are not fully dried and cured before being put into use, especially walking on them or placing heavy objects on them, it will cause the tiles and the cement layer to delaminate, and then warp. 5. Environmental factors: Seasonal changes, large indoor temperature differences and other factors will also cause thermal expansion and contraction of tiles. If the gaps between the tiles are not reserved enough, arching is likely to occur.

[0004] At present, the treatment method for bulging and warping of ceramic tiles is usually to cut out the ceramic tiles along the joint edges, then remove the old adhesive (cement) in the cut area of ​​the ground, lay the renovation materials on the ground substrate, and then stick the ceramic tiles (coated with water-based adhesive) back to the original position to complete the repair. Before re-laying the ceramic tiles, the key step is to treat the base layer with a ceramic tile renovation interface agent. Existing interface agents usually take some time to dry and solidify after being applied to the base layer, and the general drying and curing time is 12-24 hours. However, in some areas with heavy precipitation and coastal areas with heavy humidity, during the ceramic tile renovation process, after the interface agent is applied, during the drying and curing process, if there is rainy weather or humid weather, water will come into contact with the interface agent, which can easily affect the adhesion performance of the interface agent. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem that the renovation material (interface agent) in the prior art has poor adhesion performance when used in areas with heavy precipitation and coastal areas with heavy humidity, and to provide a renovation material for preventing ceramic tiles from bulging and warping, and a preparation method and application thereof.

[0006] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] A renovation material for bulging and warping tiles, comprising a first component and a second component to be mixed;

[0008] Wherein, the first component comprises, by weight:

[0009] 10-25 parts by weight of calcined kaolin;

[0010] 5-10 parts by weight of titanium dioxide;

[0011] 5-15 parts by weight of talc;

[0013] Wherein, the second component comprises by weight:

[0014] Water 5-15 parts by weight;

[0015] Emulsion 15-25 parts by weight;

[0019] As a further optimization of the renovation material for bulging and warping tiles of the present invention: the emulsion is a styrene acrylic emulsion.

[0020] As a further optimization of the renovation material for bulging and warping tiles of the present invention: the acrylic resin is a thermoplastic acrylic resin.

[0021] As a further optimization of the renovation material for bulging and warping tiles of the present invention: the defoaming agent is a silicone defoaming agent or a polyether defoaming agent.

[0022] As a further optimization of the renovation material for bulging and warping tiles of the present invention: the calcined kaolin is calcined kaolin passing through an 800-1200 mesh sieve, and the titanium dioxide is rutile titanium dioxide.

[0023] The present invention also provides a method for preparing the above-mentioned renovation material, comprising the following steps:

[0024] S1, mixing calcined kaolin, titanium dioxide, talc and soda lime and stirring evenly to obtain a first component;

[0025] S2, mixing water, emulsion, acrylic resin, dichlorobutane and defoamer and stirring evenly to obtain a second component;

[0026] S3. Seal the first component and the second component separately. When using, mix the first component and the second component and stir them evenly to obtain the renovation material.

[0027] The stirring conditions in step S1 are: stirring at a speed of 500-600 r / min for 0.5-1 h, the stirring conditions in step S2 are: stirring at a speed of 2000-3000 r / min for 1-2 h, and the stirring conditions in step S3 are: stirring at a speed of 1500-2000 r / min for 0.5-1 h.

[0028] The present invention also provides an application of the above-mentioned renovation material in the renovation construction of bulging and warping tiles. The renovation construction method is specifically: cutting out the warped tiles along the splicing edges, applying the renovation material on the floor or wall area corresponding to the cut tiles and drying and forming them, applying water-based adhesive on the back of the tiles, and then paving the tiles back to their original positions.

[0029] The invention has the following beneficial effects: the renovation material of the invention is divided into two components, wherein the first component contains soda lime, which is mainly composed of calcium oxide, sodium hydroxide and potassium hydroxide. When the first component is mixed with the second component, the calcium oxide in the soda lime can react with water to generate calcium hydroxide, which is conducive to forming a strong alkaline environment. At the same time, the reaction is an exothermic reaction, and heat is released during the reaction process. In the mixed system, dichlorobutane is hydrolyzed under alkaline conditions and high temperature conditions to form a large amount of free butanol, and the free butanol is attached to a fixed surface to form a hydrophobic film, thereby playing a role in strengthening the hydrophobicity of particles in the system and enhancing the resistance to water.

[0090] <Water resistance>

[0091] The water resistance of the renovation materials prepared in Example <1-6> and Comparative Example <1-3> was tested. The testing method was carried out according to the method in JGJ110-2008, specifically:

[0092] Remove the lifted tiles, and then apply the mixed renovation materials on the concrete substrate. Spray the coating layer with water 6h, 8h, 10h and 12h after coating, with a water spraying amount of 1.5g / cm 2 , 24 hours after coating, apply water-based adhesive on the back of the ultra-thin tile, and then lay the ultra-thin tile on the coated surface of the concrete and press hard. After 10 hours, bond the standard block to the tile, and use a through-type jack to test the bonding force of the tile. The specific performance test results are shown in Table 1 below.

[0093] Table 1: Performance Test

[0094]

[0095] It can be seen from the above table that after the water-repellent component is added, the bonding strength of the samples in Example <1-6> under the four test scenarios of 6h water spraying, 8h water spraying, 10h water spraying and 12h water spraying is higher than that of Comparative Example <1-3>. <1> Compared with the comparative example <1-3>, the bonding strength is quite different. In the test scenario of 12h water spraying, the bonding strength of the embodiment <1-3> is <1> Compared with the comparative example <1-3>, the difference in bonding strength is small. The inventor believes that this is because the renovation material is nearly dry after 12 hours, and the effect of water spraying on its bonding performance is small. The bonding strength of each comparative example in comparative example <1-3> and embodiment <1-6> in each test scenario is not much different. This is because the water-resistant components in the two components complement each other and are indispensable.

[0096] The construction method of renovating tiles using the renovation material of the present invention can also be: cutting out the warped tiles along the splicing edges or using suction cups to vertically take out the loose tiles, coating the renovation material on the back of the tiles and then paving the tiles back to their original positions, with a coating thickness of 1-2 mm.

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
