[0151] The preparation method of the ceramic tile renovation coating of the present invention comprises: by mixing the following components, the tile renovation coating is obtained:

[0152] The parts by weight of each component of the coating are as follows:

[0153] Film-forming substance: 40-80 parts by weight, the film-forming substance is selected from acrylic emulsion;

[0154] Film-forming aid: 0-10 parts by weight, the film-forming aid is 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate;

[0155] Cosolvent: 0-5 parts by weight,

[0156] Dispersant: 0-3 parts by weight,

[0157] Defoamer: 0-1 parts by weight,

[0158] Thickener: 0-3 parts by weight,

[0159] pH regulator: 0-1 parts by weight,

[0160] Adhesion promoter: 0-1 parts by weight,

[0161] Antifungal agent: 0-1 parts by weight,

[0162] Preservative 0-1 weight part,

[0163] Appropriate amount of water.

[0164] In a preferred example, the tile renovation paint is added in the following order:

[0165...

Embodiment 1

[0194] Refurbishment object:

[0195] The experimental building of a paint factory needs to be refurbished. The exterior wall tiles used to be used in the past have become very dilapidated due to the age. However, if the exterior wall tiles need to be removed again, the cost will be high and the construction time will be long. It will be unavoidable impact on daily work.

[0196] Paint formulation:

[0197] Choose to use tile refurbishment paint formula based on 100Kg, first put 15Kg of water into the dispersion tank, the speed is controlled at 800-1000 rpm; then add 60Kg of film-forming material, stir for 5 minutes; mix 1.5Kg of dispersant, 0.5Kg Defoamer and 3Kg thickener were slowly added into the dispersion tank for 15 minutes; then 5Kg of water was added to cool down; then 2.7Kg of cosolvent and 6Kg of film-forming aid were added and stirred for 5 minutes; 0.1Kg preservative, stir for 3 minutes; then add 0.2KgpH regulator, disperse for 3 minutes; then add 0.5Kg adhe...

Embodiment 2

[0204] Refurbishment object:

[0205] A small apartment in Hong Kong is undergoing exterior wall renovation, and the 60° gloss of the renovation paint needs to reach 60, and artificial aging is required for 1000 hours.

[0206] Paint preparation

[0207] Choose to use tile refurbishment paint formula based on 100Kg, first put 3Kg of water into the dispersion tank, the speed is controlled at 800-1000 rpm; then add 75Kg of film-forming material, stir for 5 minutes; mix 1.5Kg of dispersant, 0.5Kg Add defoamer and 2.8Kg thickener slowly into the dispersion tank for 15 minutes; then add 2Kg water to cool down; then add 3.2Kg co-solvent and 7.3Kg film-forming aid, stir for 5 minutes; then add 2Kg anti-mold Add 0.1Kg preservative and stir for 3 minutes; then add 0.2KgpH regulator and disperse for 3 minutes; then add 0.6Kg adhesion promoter and disperse for 5 minutes; finally add 1.8Kg water to adjust the viscosity to (70-76)KU, That is, it is made into a finished product.

Abstract

The invention discloses a renovating coating for waterborne ceramic tiles and a preparation method thereof. The coating comprises the following compositions by weight: 40 to 80 parts by weight of film-forming material, 0 to 10 parts by weight of film-forming additive, 0 to 5 parts by weight of cosolvent, 0 to 3 parts by weight of dispersing agent, 0 to 1 part by weight of defoaming agent, 0 to 3 part by weight of thickening agent, 0 to 1 part by weight of pH conditioning agent, 0 to 1 part by weight of adhesive force accelerator, 0 to 1 part by weight of mildewproof agent, 0 to1 part by weight of corrosion resistant agent and a right amount of water, wherein the film-forming material is taken from acrylic acid emulsions, and the film-forming additive is 2,2,4-trimethyl-1,3-pentanediol isobutyrate. The renovating coating for waterborne ceramic tiles is safe and environment-friendly, is easy to implement, is a multi-functional, environment-friendly and economic coating with high quality and can be widely applied to the renovation of the ceramic tiles.

Description

technical field [0001] The invention relates to a synthetic resin tile renovation paint and a preparation method thereof, more specifically to a tile renovation exterior wall paint with acrylic resin as the main film-forming substance and a preparation method thereof. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It not only has the function of preventing the surface of buildings, ships, machinery, etc. Strong fine chemical product. [0003] As we all know, latex paint is usually composed of emulsion, pigments and fillers, paint additives and water and other components. After the water evaporates, dries and coalesces to form a film, the coating film is composed of solid polymers, pigments and fillers, some additives and pores. Among them, the solid polymer is the part left after the emulsion water evaporates, its size is about 0.05-5μm, its particle size distribution o...
