A renovation material for tile bulging and warping, its preparation method and application

Abstract

The present invention discloses a renovation material for tile bulging and warping, its preparation method and application. The renovation material includes a first component and a second component used in combination. The first component includes: 10-25 parts of calcined kaolin, 5-10 parts of titanium dioxide, 5-15 parts of talcum powder, and 5-15 parts of soda lime; the second component includes: 5-15 parts of water, 15-25 parts of emulsion, 0.5-1.5 parts of acrylic resin, 0.1-0.5 parts of defoaming agent, and 4-10 parts of dichlorobutane. The first component of the renovation material of the present invention contains soda lime. When the first component is mixed with the second component, calcium oxide in the soda lime can react with water to generate calcium hydroxide, which is beneficial to the formation of a strong alkaline environment. At the same time, this reaction is an exothermic reaction, and heat will be released during the reaction process; in the mixed system, dichlorobutane hydrolyzes under alkaline conditions and high temperature conditions to form a large amount of free butanol. The free butanol can form a hydrophobic film when attached to the fixed surface, thereby strengthening the hydrophobicity of the particles in the system and enhancing the resistance to water.

Description

Technical Field

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

[0002] With the improvement of people's living standards, the demand for home decoration is also increasing. 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 arch.

[0003] The reasons for tile bulging and warping usually include the following: First, the thermal expansion and contraction of tiles: During long-term use, tiles are affected by temperature and undergo thermal expansion and contraction. If there is not enough expansion joint reserved during tile paving, or the joint is blocked by fillers, the tiles cannot release stress during expansion, resulting in arching. Second, improper construction: During construction, if the ratio of cement to yellow sand is incorrect, such as low cement grade and too much yellow sand, it will lead to insufficient bonding force of the cement layer, and then cause tile warping. Third, improper ground foundation treatment, such as the ground being too smooth without roughening treatment, will also affect the bonding between the tile and the cement layer. Fourth, improper material selection or use: The quality of the tile adhesive used does not meet the standard, or after the tiles are laid, if they are not fully dried and cured before being put into use, especially when walking or placing heavy objects on them, it will cause the tiles to delaminate from the cement layer, and then warping occurs. Fifth, environmental factors: Seasonal changes, large indoor temperature differences and other factors will also cause thermal expansion and contraction of tiles. If the tile joints are not reserved enough, arching is likely to occur.

[0004] Currently, the common treatment method for tile bulging and warping is as follows: Cut out the tile along the splicing edge, then remove the old adhesive (cement) in the ground cutting area. After laying the renovation material on the ground substrate, then stick the tile (coated with water-based adhesive) back to its original position to complete the repair. Before re-laying the tile, the key step is to treat the base layer with a tile renovation primer. The existing primer usually needs a period of time to dry and cure after being applied to the base layer, and the general drying and curing time is 12 - 24 hours. However, in some areas with more precipitation and coastal areas with high humidity, during the tile renovation process, when the primer is applied and during the drying and curing process, if it encounters rainy weather or a humid weather, the contact between water and the primer is likely to affect the adhesion performance of the primer. Summary of the Invention

[0005] The purpose of the present invention is to solve the technical problem of poor adhesion performance of the existing renovation material (primer) when used in areas with more precipitation and coastal areas with high humidity, and to provide a renovation material for tile bulging and warping, a preparation method thereof, and an application thereof.

[0006] To solve the deficiencies of the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A renovation material for the bulging and warping of ceramic tiles, comprising a first component and a second component used in combination;

[0008] Among them, the first component includes, by weight parts:

[0009] Calcined kaolin 10 - 25 weight parts;

[0010] Titanium dioxide 5 - 10 weight parts;

[0011] Talc powder 5 - 15 weight parts;

[0012] Soda lime 5 - 15 weight parts;

[0013] Among them, the second component includes, by weight parts:

[0014] Water 5 - 15 weight parts;

[0015] Emulsion 15 - 25 weight parts;

[0016] Acrylic resin 0.5 - 1.5 weight parts;

[0017] Defoamer 0.1 - 0.5 weight parts;

[0018] Dichlorobutane 4 - 10 weight parts.

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

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

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

[0022] As a further optimization of the renovation material for the bulging and warping of ceramic 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 preparation method of the above renovation material, comprising the following steps:

[0024] S1. Mix the calcined kaolin, titanium dioxide, talc powder, and soda lime and stir evenly to obtain the first component;

[0025] S2. Mix the water, emulsion, acrylic resin, dichlorobutane, and defoamer and stir evenly to obtain the second component;

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

[0027] Among them, 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 the application of the above renovation material in the renovation construction of tiles with bulging and warping. The renovation construction method is specifically as follows: Cut out the warped tiles along the splicing edge, coat the renovation material on the ground or wall area corresponding to the cut tiles and dry and form it, apply a water-based adhesive on the back of the tiles, and then lay the tiles back to their original positions.

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

[0090] <Water resistance>

[0091] Perform water resistance tests on the refurbishing materials prepared in Examples <1-6> and Comparative Examples <1-3>. The detection method for this time refers 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.
