Description

Technical Field

[0001] The present invention belongs to the field of primer for colored stone metal tiles, and particularly relates to a heat-insulating primer composition, a preparation method and an application thereof. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Solar radiation is intense in hot regions. In such an environment, the temperature of the roof can easily reach about 80 °C. Due to the poor heat insulation of traditional roofs, a large amount of heat enters the room through the roof, resulting in a high indoor temperature and affecting the living comfort.

[0004] In such an environment, although the colored sand layer of the colored stone metal tile can improve the heat insulation performance of the colored stone metal tile to a certain extent, the aluminized zinc steel plate substrate has good heat transfer and conduction effects. Therefore, it is difficult for the colored stone metal tile to meet the heat insulation requirements. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a heat-insulating primer composition, a preparation method and an application thereof.

[0006] To achieve the above purpose, the present invention is realized by the following technical solutions:

[0007] In the first aspect, the present invention provides the application of magnesium hydroxide and / or aluminum hydroxide in the preparation of a heat-insulating primer for colored stone metal tiles.

[0008] In the second aspect, the present invention provides a heat-insulating primer composition for colored stone metal tiles, including water, a binder and heat-insulating powder. Among them, the heat-insulating powder is magnesium hydroxide or / and aluminum hydroxide, and the mass ratio of water, the binder and the heat-insulating powder is 1-1.5:4.5-5.5:3-4.5.

[0009] The heat-insulating binder or heat-insulating coating includes the following three types:

[0010] 1. Heat-barrier type heat-insulating binder (coating), which uses a low thermal conductivity system to shield heat exchange to achieve heat insulation. After this kind of binder is coated and formed into a film, the film is filled with pores, and the density of the dry film is very low. The pore structure is used to achieve a low thermal conductivity coefficient.

[0011] 2. Heat-radiation type heat-insulating binder (coating): It emits the absorbed heat in the form of wave radiation at a certain wavelength into the air, thereby achieving a cooling effect.

[0012] 3. Heat-reflection type heat-insulating coating: It reflects the visible light and near-infrared light parts in the sun to the external space through the reflection of the coating film, so that most of the energy of the sun irradiated on the coating film is reflected, and thus heat insulation is achieved.

[0013] The structure of the colored stone metal tile from one side to the other is a protective layer, an aluminized zinc layer, a steel base layer, an aluminized zinc layer, a protective layer, a base adhesive layer, a colored stone layer, and a surface layer. Therefore, the base adhesive layer is located between the metal substrate and the colored stone layer, and there is also a surface layer outside the colored stone layer. The colored stone layer has good light-shielding properties. Due to the special position of the base adhesive layer, it is difficult to use the principle of heat reflection for heat insulation of the base adhesive.

[0014] On the other hand, the colored stone is sintered colored sand, which is made of basalt particles of a certain particle size through a coloring process or high-temperature sintering and has a certain heat insulation effect. The installation state of the colored stone metal tile is that the metal tile substrate is close to the roof and the colored stone layer faces outward. When the base adhesive uses the heat radiation heat insulation principle for heat insulation, the heat absorbed by the base adhesive layer is emitted outward in the form of heat radiation. Since the colored sand has a certain heat insulation effect, and the temperature on the side of the colored sand layer is high, while the thermal conductivity coefficient of the metal tile substrate is large and the temperature is low. In this case, most of the heat absorbed by the base adhesive layer will be emitted to the interior of the building through the metal tile substrate. Therefore, it cannot achieve the expected heat insulation effect, and thus the base adhesive for colored stone metal tiles cannot use the heat radiation heat insulation principle for heat insulation.

[0015] Therefore, the base adhesive for colored stone metal tiles can only use the method of reducing the thermal conductivity coefficient, that is, using the heat barrier type heat insulation principle for heat insulation.

[0016] The colored sand layer of the colored stone metal tile is bonded to the aluminized zinc steel plate substrate through the base adhesive. In the use state, it is exposed to the natural environment and needs to withstand wind, sun, rain, and even hail strikes. Its service life needs to reach more than 30 years. Therefore, the adhesion performance of the colored sand on the metal tile substrate is the most basic performance requirement.

[0017] However, the coating film of the heat barrier type heat insulation adhesive in the prior art is full of pores, and the pore structure of the dry coating film is used to reduce its thermal conductivity coefficient to achieve heat insulation. However, the existence of the pore structure will inevitably seriously affect the bonding strength and bonding durability of the colored sand on the metal tile substrate.

[0018] The finished product thickness of the colored stone metal tile is 1 - 3 mm. The thickness requirement for most types of colored stone metal tiles is 1.8 mm, such as classic arc tiles, Roman rainbow tiles, W-shaped bevel tiles, wood grain bevel tiles, square grid tiles, Milan tiles, reinforced classic tiles, and relief tiles, etc. Among them, the thickness of the aluminized zinc steel plate is about 0.4 mm, and the total thickness of the protective layer, base adhesive layer, colored stone layer, and surface layer on both sides of the aluminized zinc steel plate is about 1.4 mm. Therefore, the thickness of the base adhesive layer is very small.

[0019] In addition, the primer is atomized and sprayed onto the metal tile substrate to form a liquid film, and colored sand is sprinkled on the liquid film. Since the colored sand has a certain weight and a certain falling speed, when the colored sand stays in the primer liquid film, it will be partially impregnated below the primer liquid film. In this case, the distance between the colored sand and the metal tile substrate is further reduced, which is less than the actual thickness of the primer layer.

[0020] The thermal conductivity refers to the amount of heat transferred through an area of 1 square meter in 1 second under steady heat transfer conditions, with a temperature difference of 1 °C between the two surfaces of a 1 m thick material, and its unit is watt per meter per degree. When the thickness of the primer layer is very small, even if the thermal conductivity of the primer is very small, the amount of heat transferred per unit time and unit area is relatively large, that is, the heat insulation effect is poor.

[0021] Therefore, if the primer layer of the colored stone metal tile wants to obtain a good heat insulation effect, the requirement for its thermal conductivity is very high.

[0022] The inventor of the present invention first proposed to improve the heat insulation performance of the primer by adding heat insulation materials (such as heat insulation powder) to the primer. During the research and development process, a large number of heat insulation powders were tested. It was found that although the addition of some heat insulation powders could improve the heat insulation performance of the primer to a certain extent, it would seriously affect other properties of the primer, especially the bonding property, and thus could not guarantee the basic property requirements of the primer. At present, the inventor has not found other heat insulation powders other than magnesium hydroxide and aluminum hydroxide that can simultaneously meet the bonding property and heat insulation performance requirements of the primer.

[0023] In order to make the primer have better heat insulation performance, the heat insulation powder in the primer composition is a mixture of magnesium hydroxide and aluminum hydroxide, and the mass ratio of magnesium hydroxide to aluminum hydroxide is 0.5 - 1.5:0.5 - 1.5, preferably 0.7 - 1.2:0.7 - 1.2.

[0024] The binder of the primer is selected from one or more of styrene-acrylate copolymer emulsion (styrene-acrylate copolymer emulsion), elastic emulsion, ethylene-vinyl acetate copolymer emulsion, polyurethane-acrylate copolymer emulsion, fluororesin-modified polyacrylate resin emulsion, silicone-modified polyacrylate (silicone-acrylic) emulsion or ethylene-acrylate copolymer emulsion. The elastic emulsion is a copolymer of acrylate and silicone, and has excellent resilience, flexibility, adhesion, waterproofness, weather resistance, dust accumulation resistance and ultraviolet resistance.

[0025] It has been found through experiments that the binder with better heat insulation performance is a composition of styrene-acrylate copolymer emulsion and elastic emulsion. The mass ratio of styrene-acrylate copolymer emulsion to elastic emulsion is 1.5 - 3:1, preferably 1.5 - 2:1. At the same time, when these two emulsions are used in combination in proportion, in addition to helping to improve the heat insulation performance of the primer, it can also effectively improve the film-forming characteristics and atomization characteristics of the primer.

[0026] In the heat-insulating primer composition, the mass percentage of water is 10%-20%, preferably 10%-15%, and further preferably 10%-13%. Appropriately increasing the water content in the primer can not only effectively improve the atomization effect of the primer, but also help improve the film-forming characteristics of the primer. The improvement of the atomization performance and film-forming performance is beneficial to improving the uniformity of the primer adhering to the surface of the metal tile substrate, and thus beneficial to improving the product quality of the colored stone metal tile. Therefore, the atomization performance and film-forming performance of the primer are relatively important factors.

[0027] It has been found through experiments that when the water content in the primer is too low, the atomization performance of the primer is poor, and the film-forming performance of the primer is also poor. When the water content is too high, it will affect the content of other components in the primer, and thus is not conducive to the improvement of other aspects of the primer performance. When the mass percentage of water is 10%-15%, or even 10%-13%, it can not only make the primer have good atomization performance and film-forming performance, but also promote the uniform dispersion of each component in the primer, which is beneficial to improving the stability of the primer and is relatively beneficial to the improvement of the bonding performance of the primer.

[0028] In order to improve the film-forming performance of the primer composition during spraying, a film-forming aid can also be added to the primer composition. Preferably, the film-forming aid is selected from benzyl alcohol, ethylene glycol monobutyl ether or dodecyl alcohol ester.

[0029] The film-forming aid can promote the plastic flow and elastic deformation of the primer, improve the coalescence performance, enable the atomized and sprayed primer to form a film on the metal substrate, and improve the uniformity of the primer distribution, so as to improve the adhesion uniformity and bonding strength of the colored sand on the surface of the metal substrate.

[0030] The combination of the film-forming aid and a suitable water content enables the atomized and sprayed primer to be more evenly distributed on the metal tile substrate and form a film, so as to improve the adhesion uniformity and adhesion strength of the colored sand on the surface of the metal tile substrate, and effectively improve the quality and aesthetics of the colored stone metal tile.

[0031] The heat-insulating primer composition also includes kaolin and / or heavy calcium. Preferably, the mass ratio of kaolin to heavy calcium is 1:1.2-3, and preferably 1:1.2-1.5.

[0032] Both kaolin and heavy calcium have the function of assisting in enhancing the heat-insulating performance of the primer. At the same time, the combination of kaolin and heavy calcium can effectively improve the bonding performance (the bonding performance between the colored sand and the metal tile substrate) and waterproof performance of the primer.

[0033] Furthermore, the heat-insulating primer composition also includes a wetting agent. Preferably, the wetting agent is an anionic surfactant, a polyol type surfactant (such as Span or Tween) or a polyoxyethylene type surfactant.

[0034] When using a primer to bond a metal substrate and colored sand, if the primer can be fully wetted with both, the adhesion performance to both can be effectively improved. Adding a wetting agent can effectively improve the wetting effect of the primer on both, thereby improving the adhesion. Therefore, the addition of kaolin, heavy calcium, and a wetting agent can better improve the adhesion performance of the primer. In addition, using the above specific wetting agent is beneficial to improving the toughness of the primer film after curing, and thus beneficial to improving the impact resistance of the colored stone metal tile.

[0035] To improve the stability of the primer, a dispersant and / or a thickener can also be added to the heat-insulating primer composition.

[0036] Since magnesium hydroxide, aluminum hydroxide, and even kaolin or / and heavy calcium are added to the heat-insulating primer, and these substances are insoluble in water, adding a dispersant to the heat-insulating primer can improve the dispersion uniformity of the heat-insulating primer and prevent the heat-insulating primer from stratifying during transportation, storage, and use, which affects the application effect.

[0037] At the same time, the thickener can increase the consistency of the heat-insulating primer and further increase the viscosity of the primer. The combined use of a dispersant and a thickener can better improve the stability of the primer. In addition, the addition of the thickener is beneficial to improving the anti-aging performance of the primer, and thus promotes the improvement of the weather resistance of the colored stone metal tile.

[0038] Preferably, the thickener is selected from one or a mixture of more of inorganic thickeners, cellulose thickeners, fatty alcohol thickeners, fatty acid thickeners, ether thickeners, polyacrylate thickeners, or associative polyurethane thickeners. Preferably, it is a polyacrylate thickener.

[0039] Preferably, the dispersant is selected from polycaprolactone polyol-polyethyleneimine block copolymer type dispersants, acrylate polymer type dispersants, polyurethane or polyester type polymer dispersants. Preferably, the dispersant is an acrylate polymer type dispersant.

[0040] Stirring during the production process of the primer and the reaction between various components, as well as the shaking that occurs during the transportation of the primer, may introduce foam into the primer. The presence of foam will seriously affect the adhesion performance of the primer and the quality of the colored stone metal tile. Adding an antifoaming agent to the heat-insulating primer composition can effectively avoid the generation of foam, and since the addition amount of the antifoaming agent is small, it will not affect the overall performance of the primer.

[0041] During the process of spraying colored sand onto the primer coating, it is possible to introduce air into the primer coating to form bubbles. Therefore, adding an antifoaming agent to the primer can promptly eliminate the bubbles and improve the uniformity and firmness of the adhesion between the colored sand and the metal substrate.

[0042] In addition, the presence of the defoamer also helps to improve the uniform stability of the primer, which is beneficial to preventing the sedimentation of the primer during storage, transportation and use.

[0043] Preferably, the defoamer is selected from emulsified silicone oil, high-carbon alcohol fatty acid ester complex, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene amine ether, polyoxypropylene glycerol ether, polyoxypropylene polyoxyethylene glycerol ether or polydimethylsiloxane.

[0044] In some embodiments, the heat-insulating primer composition further comprises an amine neutralizer, a bactericide and / or an aqueous carbon black paste.

[0045] Adding an amine neutralizer to the primer can adjust the pH value of the primer, thereby improving the storage and use stability of the primer. During transportation, storage and use, the primer is easily eroded by various bacteria, molds, fungi and yeasts, seriously affecting the bonding performance, odor and appearance of the primer, and further affecting the service life of the colored stone metal tile. Adding a bactericide to the primer can effectively solve this problem. Adding an aqueous carbon black paste to the primer can effectively improve the weather resistance of the primer. The addition of the three substances can effectively improve the stability of the primer.

[0046] The heat-insulating primer composition further comprises a combination of two or more of a film-forming auxiliary agent, kaolin, heavy calcium, a wetting agent, a dispersing agent, an amine neutralizer, a bactericide, a defoamer, an aqueous carbon black paste or a thickening agent.

[0047] Preferably, the heat-insulating primer composition is composed of the following components in parts by weight: 25-70 parts of a binder, 10-20 parts of water, 20-40 parts of heat-insulating powder, 0.1-0.3 part of a wetting agent, 0.25-0.4 part of a dispersing agent, 0.15-0.3 part of an amine neutralizer, 0.15-0.3 part of a bactericide, 0.15-0.4 part of a defoamer, 5-15 parts of kaolin, 5-15 parts of heavy calcium, 0.5-2 parts of an aqueous carbon black paste, 0.5-1.5 parts of a film-forming auxiliary agent, 0.1-1.5 parts of a thickening agent;

[0048] The heat-insulating powder is magnesium hydroxide and / or aluminum hydroxide.

[0049] In a third aspect, the present invention provides a heat-insulating primer for a colored stone metal tile, which is prepared from the heat-insulating primer composition for a colored stone metal tile.

[0050] In a fourth aspect, the present invention provides a preparation method of the heat-insulating primer for a colored stone metal tile, comprising the following steps: mixing water, a binder and heat-insulating powder evenly to obtain the heat-insulating powder being magnesium hydroxide or / and aluminum hydroxide.

[0051] Preparation method of heat-insulating base glue, comprising the following steps: First, mix a wetting agent, a dispersant, an amine neutralizer, a bactericide, an antifoaming agent and part of water in proportion to obtain a first mixed solution;

[0052] Add part of a binder, kaolin, heavy calcium, aqueous carbon black paste, heat-insulating powder and part of water to the first mixed solution in proportion and mix evenly to obtain a second mixed solution;

[0053] Then add the remaining binder and a film-forming aid to a third mixed solution to obtain a fourth mixed solution;

[0054] Finally, adjust the viscosity of the base glue to obtain the product.

[0055] Fifth aspect, the present invention provides a colored stone metal tile, the base glue of which is the heat-insulating base glue for the colored stone metal tile.

[0056] Sixth aspect, the present invention provides a preparation method of the colored stone metal tile, comprising the following steps:

[0060] After adding a certain mass fraction of magnesium hydroxide and / or aluminum hydroxide to the mixture of water and binder, the heat-insulating performance of the base glue can be significantly improved.

[0061] In addition, magnesium hydroxide and / or aluminum hydroxide also exhibit good fireproof performance, and their addition improves the fireproof performance of the base glue to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
