Description

Technical Field

[0001] The present application relates to the field of stone processing technology, and in particular to a stone color difference treatment agent and its application. Background Art

[0002] Stone is widely used in architecture, home furnishings, artwork, and decorative items. The raw materials for stone processing all come from various mines. Differences in mining environments can lead to color variations among the same stone. To achieve color differentiation between stones, coloring is performed using a variety of methods, including physical pigmentation, physical-chemical coloring, and chemical reaction coloring. Physical coloring primarily mechanically infuses pigments into the stone, but this method can lead to pigment accumulation in cracks within the stone, resulting in uneven coloration. Therefore, it is currently less commonly used.

[0003] Physical-chemical coloring and chemical reaction coloring are based on the natural color of the stone and the color of other colors. Generally, inorganic materials and organic colorants are used as the main colorants. The pigments are introduced into the stone and then converted into elemental precipitation through chemical reactions to achieve the coloring effect. Among them, the advantage of inorganic coloring is strong weather resistance and poor dyeing properties. The advantage of organic coloring is rich and bright colors, but the weather resistance of some materials is often not ideal. Using inorganic coloring or organic coloring alone cannot make the dyed stone have both weather resistance and dyeing properties, so it needs to be improved. Summary of the Invention

[0004] In order to solve the problem that existing dyed stone cannot have both weather resistance and dyeability, the present application provides a stone color difference treatment agent and its application.

[0005] In the first aspect, the present application provides a stone color difference treatment agent and its application, which adopts the following technical solutions:

[0006] A stone color difference treatment agent is prepared from the following raw materials in parts by weight:

[0007] 1-10 parts of dye

[0008] 5-13 parts of penetrant

[0009] 10-20 parts of colorless and transparent epoxy resin

[0010] 5-15 parts paraffin oil

[0011] 2-4 parts active agent

[0012] 1-4 parts organic acid

[0013] 20-40 parts of diluent;

[0014] The dye contains an organic pigment.

[0015] By adopting the above technical solution, the stone color difference treatment agent can quickly penetrate into the stone to form a stable pigment precipitation, with excellent dyeing properties and long-term color change resistance, achieving excellent weather resistance. In this application, the combined use of a dye, paraffin oil, and a colorless and transparent epoxy resin can effectively slow the dye's color change time and improve the weather resistance of the stone color difference treatment agent after drying. At the same time, the color difference rate of the same batch of stone treated with this stone color difference treatment agent is reduced.

[0016] The deeper the stone color difference treatment agent penetrates, the better the dyeing effect. Conversely, the weaker the stone color difference treatment agent's penetration ability, the weaker the dyeing effect and the more likely it is to fade or discolor. The activator and penetrant in this application help the stone color difference treatment agent penetrate into the pores on the stone surface and penetrate deeper, while preventing the stone color difference treatment agent from accumulating in a single area of ​​the stone and causing uneven color.

[0017] In addition, organic acids help the penetrant penetrate into the gaps on the stone surface and diffuse with the help of diluents, so that the dye can penetrate deeper into the stone, improving the dyeing effect. It also makes the color distribution on the stone surface more uniform, reduces color difference, and allows the dye to settle in the gaps on the stone surface, keeping the color unchanged for a long time.

[0018] The dyes described in this application contain organic pigments, which can improve the tinting power of the stone color difference treatment agent and are available in a wide variety of varieties. However, organic pigments have poor weather resistance, light resistance, water resistance, and heat resistance. To address this issue, this application improves the weather resistance, light resistance, water resistance, and heat resistance of the stone color difference treatment agent by preparing the organic pigments into a dye and then combining the dye with paraffin oil and colorless, transparent epoxy resin.

[0019] The present invention uses paraffin oil as a component of the dye, effectively protecting the dye from contaminants. However, paraffin oil can block the pores and interstices of the stone, rendering the stone airtight and affecting the dyeing effect. To address this issue, the present invention utilizes paraffin wax, an organic acid, and a penetrant to prevent the paraffin oil from clogging the pores and interstices of the stone, while also maintaining the paraffin oil's ability to protect the dye from contaminants.

[0020] Furthermore, the raw materials used in this application cause no damage to the environment and are environmentally friendly.

[0021] Preferably, the dye is a cyclohexylacetone modified dye, which is prepared by the following method:

[0022] 1) Mix the organic pigment and ethanol, heat to 60-65° C., then add polyethylene glycol and stir evenly to obtain a mixed solution;

[0023] 2) Mix cyclohexyl acetone and 1,2-cyclohexanediamine under reflux at 70-80°C, add a catalyst, react for 1-2 hours, then add the mixture and stir evenly to obtain a primary product;

[0024] 3) Add acetic acid dropwise to the primary product to adjust the pH of the primary product to 6.5-6.7, then add turpentine water and stir evenly to obtain a cyclohexylacetone-modified dye.

[0025] By adopting the above technical solution, the ability of the slate color difference treatment agent to penetrate the pores on the stone surface is further improved, and the organic pigment is also prevented from changing color or fading during use. The chemical stability of the organic pigment is relatively poor, and it is easily affected by light, oxygen, water and temperature and changes. To this end, in the present application, the cyclohexyl acetone modified coloring agent is prepared by combining organic pigment, ethanol, polyethylene glycol, cyclohexyl acetone, 1,2-cyclohexanediamine, catalyst, acetic acid and turpentine to improve the chemical inertness of the organic pigment, reduce its reactivity, and is not easily affected by light, oxygen, water and temperature and changes.

[0026] In addition, the organic acid added in this application is to help the penetrant penetrate into the gaps on the stone surface, but at the same time, the organic acid can reduce the antioxidant, UV resistance, and weather resistance of the dye. However, the cyclohexylacetone-modified dye prepared in this application is not affected by the organic acid, which can reduce the antioxidant, UV resistance, and weather resistance of the dye.

[0027] In this application, it is not only necessary to allow the organic pigment to penetrate into the pores to form pigment precipitation, but also to fix the color of the organic pigment to prevent the stone from fading during use. The organic pigment in this application can be self-mixed according to actual needs.

[0028] Preferably, the weight parts of the raw materials used to prepare the cyclohexylacetone modified dye are as follows:

[0029] 2-5 parts organic pigment

[0030] 10-15 parts of ethanol

[0031] 3-7 parts polyethylene glycol

[0032] 5-10 parts of cyclohexyl acetone

[0033] 4-9 parts of 1,2-cyclohexanediamine

[0034] 1-2 parts catalyst

[0035] 4-8 parts of acetic acid

[0036] 5-9 parts of turpentine.

[0037] By adopting the above technical solution, the amount of raw materials used in preparing cyclohexylacetone-modified dyes is optimized, the dye's resistance to organic acids is further improved, and the chemical inertness of organic pigments is improved, thereby improving the dye's light resistance, oxygen resistance, water resistance, and weather resistance.

[0038] Preferably, the turpentine is prepared from α-pinene, β-pinene and ethanol in a weight ratio of (40-60): (30-45):17.

[0039] By adopting the above technical solution, the fluidity of the cyclohexyl acetone modified dye is improved, and the oxidation of the organic pigment in the cyclohexyl acetone modified dye can be further prevented. By optimizing the amount of α-pinene, β-pinene, and ethanol in turpentine, the penetrant is preferably prepared by mixing ferric nitrate, potassium permanganate, and water in a weight ratio of (10-20): (1-3): (50-70).

[0040] To further enhance the dye's penetration into the stone's crevices, pores, and tiny holes, this application utilizes the aforementioned penetrants to facilitate their penetration into the stone. This high penetration yields a superior dyeing effect, resisting fading or discoloration. The collaborative use of ferric nitrate and potassium permanganate in this application further corrodes the stone's surface, allowing the dye to quickly penetrate the stone. By optimizing the ratio of ferric nitrate and potassium permanganate, excessive corrosion of the stone, which could damage the stone's surface, is prevented. This also prevents the penetrant from being too aggressive, potentially impacting the dyeing effect.

[0041] Preferably, the active agent is one of sodium ethylhexyl sulfate, quaternary ammonium salt or fatty acid salt.

[0042] By adopting the above technical solution, it is beneficial to reduce the surface tension of the stone color difference treatment agent, making it easier for the stone color difference treatment agent to penetrate into the pores and then holes on the stone surface, thereby improving the penetration ability of the stone color difference treatment agent, further improving the dyeing efficiency, and maintaining the color for a long time.

[0043] Preferably, the organic acid includes at least one of oxalic acid, acetic acid, citric acid, malic acid, propionic acid or tartaric acid.

[0044] By adopting the above technical solution, the penetrant and diluent are used in coordination to further improve the penetration ability of the stone color difference treatment agent, so that the dye can enter the interior of the stone, thereby forming a stable dyeing layer that can be preserved for a long time without changing color.

[0045] Preferably, the colorless transparent epoxy resin has a viscosity of 200-1200 mPa.s (25° C.) and an epoxy value of 2-20 eq / 100 g.

[0046] By adopting the above technical solution, the parameters of the colorless and transparent epoxy resin are optimized, and the fluidity of the stone color difference treatment agent is further improved, thereby improving its permeability. At the same time, the weather resistance, light resistance, water resistance, and heat resistance of the stone color difference treatment agent after curing can be improved.

[0047] Preferably, the stone color difference treatment agent is prepared by the following method:

[0048] According to parts by weight, colorless transparent epoxy resin, paraffin oil and diluent are heated in a water bath while stirring until the temperature reaches 60-70°C, then organic acid and penetrant are added, stirring is continued, the temperature is lowered to 20-30°C, dye is added, and stirring is carried out to obtain a stone color difference treatment agent.

[0049] By adopting the above technical solution, a uniform and stable stone color treatment agent is obtained. The stone color treatment agent can quickly penetrate the pores and holes on the stone surface, requiring only one to two applications. After penetration, the dye forms a stable pigmentation that can maintain long-term color change. The cured product has excellent weather resistance, light resistance, water resistance, and heat resistance.

[0050] In a second aspect, the present application provides an application of a stone color difference treatment agent, which adopts the following technical solution:

[0051] An application of a stone color difference treatment agent comprises the following steps:

[0052] Material preparation: Select a stone of suitable color as the standard stone, clean the surface of the stone to be dyed and set aside; Dyeing: Stir the stone color difference treatment agent evenly, apply it evenly on the surface of the stone to be dyed, and let it dry naturally; if the color is not yet consistent with the standard stone, continue to color it after drying until it is consistent with the color of the standard stone.

[0053] By adopting the above technical solution, the color difference of the same batch of stones can be reduced, thereby ensuring the aesthetics of the same batch of stones.

[0054] In summary, this application has the following beneficial effects:

[0055] 1. This application prepares a stone color difference treatment agent by combining a dye, a penetrant, a colorless transparent epoxy resin, paraffin oil, an active agent, an organic acid, and a diluent. The use of the penetrant, active agent, and organic acid in this application enables the stone color difference treatment agent to have good penetrating properties, capable of penetrating into pores on the stone surface and deeper into the stone. The dye can also form a stable pigment precipitation inside, which can maintain long-term color change. At the same time, the combined use of the dye, paraffin oil, and colorless transparent epoxy resin can effectively slow the color change time of the dye and improve the weather resistance of the stone color difference treatment agent after drying.

[0056] 2. The present application prepares a cyclohexylacetone-modified dye by combining an organic pigment, ethanol, polyethylene glycol, cyclohexylacetone, 1,2-cyclohexanediamine, a catalyst, acetic acid and turpentine, thereby improving the chemical inertness of the organic pigment, reducing its reaction activity and making it less susceptible to changes due to light, oxygen, water and temperature.

[0103] Application Examples

[0104] Application Example 1

[0105] An application of a stone color difference treatment agent comprises the following steps:

[0106] Preparation: Select a stone of suitable color as the standard stone, clean the surface of the stone to be dyed and set aside; Dyeing: Stir the stone color difference treatment agent from Example 1 evenly, apply it evenly on the surface of the stone to be dyed, and dry it naturally; if the color is not consistent with the standard stone, continue to color it after drying until it is consistent with the color of the standard stone, color it twice, and observe whether the coloring is uniform.

[0107] By coating the marble surface with a stone color difference treatment agent, the color of the marble treated with the stone color difference treatment agent is made the same as that of the standard stone.

[0111] Performance testing

[0112] The stones prepared in Application Examples 1-18 were subjected to color difference, color fastness and sunlight fastness tests.

[0113] Detection method / test method Color difference: Use a portable spectrophotometer, brand is Caipu, model is CS-600, the light source is CLEDs, the power supply voltage is 12V, and the color difference between the standard stone and the stone of application examples 1-18 is tested. The larger the absolute value of the color difference, the greater the color difference from the standard stone.

[0114] Color fastness testing: Use a ball bearing abrasion tester to rub the dyed side of the stone material from Example 1-18. Observe the dyed layer on the rubbed area for any scratches. The NS-2 ball bearing abrasion tester has a power of 0.75 kW, a 13xΦ15.875 mm grinding head, a grinding head load of 154 N, a shaft load rated speed of 1000 r / min, and a rubbing time of 10 seconds. Visible scratches are considered obvious to the naked eye, slight scratches are visible at 40x magnification, and no scratches are considered visible even with a 40x magnifying glass.

[0115] Sunlight fastness test: Prepare a test box, cut the stone material of Application Example 1-18 into samples with an area of ​​10cm*10cm, and then place the samples side by side in the test box. Maintain the temperature in the test box at 45℃ and the humidity at 60%. Spray water into the test box every hour, 500ml each time, with ultraviolet wavelength of 290nm and irradiation intensity of 550W / m 2 The test time is one week. If the color difference value is negative, it means that the dyeing layer has changed color. The color difference of the stone in application example 1-18 is measured. The experimental data are shown in Table 4:

[0116] Table 4 Experimental data of application examples 1-18

[0117]

[0118] It can be seen from Application Examples 1-18 and Table 4 that the stone color difference treatment agent prepared by the application is used to treat the same batch of stones, which can further reduce the color difference of the same batch of stones and color them evenly. At the same time, it can improve the weather resistance of the stone dyeing layer and effectively prevent the dyeing layer from changing color.

[0119] Comparison between Example 1 and Comparative Example 1 shows that the dyeing effect of the stone color difference treatment agent can be further improved by using a colorless and transparent epoxy resin in combination with a dye, a penetrant, paraffin oil, an active agent, an organic acid and a diluent, and the friction fastness and sunlight fastness of the dyeing layer can be improved. It shows that the stone color difference treatment agent prepared by the present application can quickly penetrate into the interior of the stone to form a stable pigment precipitation, can maintain long-term non-discoloration, and achieve good weather resistance.

[0120] Comparison between Example 1 and Comparative Example 2 shows that organic acid helps to improve the dyeing effect of the stone color difference treatment agent, but reduces the weather resistance of the stone color difference treatment agent.

[0121] Compared with Example 1, the color difference in Example 4 is significantly smaller than that in Example 1. After the sun exposure test, the color difference in Example 4 remains basically unchanged, indicating that the cyclohexyl acetone modified dye prepared by the present application improves the ability of the slate color difference treatment agent to penetrate the pores on the surface of the stone, and also prevents the organic pigment from changing color or fading during use.

[0122] Comparison of Example 4 with Examples 7-10 illustrates that the cyclohexylacetone-modified dye prepared by the method and raw materials of the present application improves the chemical inertness of the organic pigment, reduces its reactivity, and is not easily affected by changes in light, oxygen, water, and temperature.

[0123] Comparison between Example 1 and Example 11 shows that the use of a suitable colorless and transparent epoxy resin can further improve the abrasion resistance and sunlight resistance of the dyeing layer.

[0124] Comparison between Example 1 and Example 12, and Example 2 and Example 13, shows that by adopting the penetrant prepared in this application, the penetration effect of the stone color difference treatment agent can be improved, thereby improving the friction resistance of the dyeing layer of the stone color difference treatment agent.

[0125] Comparison between Example 4 and Examples 14-15 shows that the use of α-pinene and β-pinene to prepare a cyclohexyl acetone-modified dye helps to reduce the chemical activity of the dye and improve the weather resistance of the stone color difference treatment agent. This specific example is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art can make modifications to the present example as needed that do not contribute to creativity, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
