Description

Technical Field

[0001] This invention relates to the field of decorative surfaces, specifically to a non-slip and cooling granular decorative surface and its preparation method. Background Technology

[0002] With economic development, buildings, swimming pools, tunnels, underground facilities, etc. are being constructed at a great pace. In order to obtain functions such as anti-slip, fireproof, and wear-resistant, it is often necessary to lay anti-slip decorative coatings on these buildings. However, the current anti-slip decorative coatings have short service life, do not have the ability to be recoated and reused, and it is difficult to simultaneously have good fire resistance, good decorative properties, good surface appearance, good waterproof effect, good exposed pressure resistance and wear resistance, and can simultaneously meet the requirements of anti-slip and polishing effects. Moreover, none of the above materials have infrared refraction function.

[0003] Patent CN105567067B reports an organic-inorganic hybrid waterproof coating and its preparation method. It uses conventional waterproof resins such as polyurea, polyurethane, and epoxy resin as raw materials, adds a compound micro-powder prepared from solid waste and sludge, and then adds a mixed modifier and thixotropic agent to prepare a component A slurry. After adding a curing agent and plasticizer, it is coated onto the corresponding substrate and cured at room temperature to obtain a waterproof coating. This material has comprehensive advantages such as good waterproof effect, high hardness, good impermeability, good corrosion resistance, low coefficient of linear expansion, high softening temperature, oxidation resistance, aging resistance, flame retardancy, and strong adhesion to the substrate. It can be used for waterproofing buildings, swimming pools, tunnels, underground facilities, etc., and can be applied on-site without wet work, forming in one step, with short construction period and low cost, showing good market prospects. However, the conventional waterproof resins such as polyurea, polyurethane, and epoxy resin used have poor high-temperature resistance, and the resulting waterproof coating has poor decorative properties.

[0004] Patent CN108290399B reports a multilayer coating with visual effects, consisting of a gel coating layer prepared from unsaturated polyester and a thixotropic agent, a visual effect layer prepared from transparent gel coating visual effect pigments, and a colored layer prepared from gel coating and simple pigments. The resulting multilayer coating has colorful visual effects and excellent transparency. However, this multilayer coating has poor flame retardant properties and does not possess infrared refraction properties.

[0005] Therefore, there is an urgent need in the market for a non-slip decorative surface with excellent high temperature resistance, flame retardancy, good infrared refraction, and good decorative properties. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to obtain a non-slip and cooling particle decorative surface that has a long service life, good decorative properties, good pressure resistance and wear resistance, good infrared refraction effect, excellent high temperature resistance and flame retardant properties, can simultaneously satisfy the anti-slip and polishing effects, and can be reused.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] The present invention provides a non-slip and cooling particle decorative surface, which, by weight, comprises the following raw materials: 70-90 parts of polygonal microporous fireproof, heat-insulating and sound-absorbing particles, 90-110 parts of multifunctional decorative particles, 40-50 parts of polysiloxane primer, and 150-200 parts of fluorosilicone resin.

[0009] The non-slip and cooling granule decorative surface prepared by this application using polygonal microporous fireproof, heat-insulating and sound-insulating granules, multifunctional decorative granules, polysiloxane, and fluorosilicone resin as raw materials has a long service life, good decorative properties, good compressive strength and wear resistance, good infrared refraction effect, high temperature resistance and excellent flame retardant properties. It can simultaneously meet the requirements of non-slip and polishing effects and can be reused.

[0010] In some embodiments, the polygonal microporous fireproof, heat-insulating, and sound-insulating particles, by weight, contain the following raw materials: 25-35 parts of vinyl acetate, 8-12 parts of single-component self-drying epoxy resin, 4-6 parts of melamine, 8-12 parts of ammonium polyphosphate, 4-6 parts of pentaerythritol, 10-20 parts of recyclable materials, and 4-6 parts of pigment.

[0011] In some embodiments, the preparation method of the polygonal microporous fireproof, heat-insulating and sound-insulating particles includes the following steps: adding vinyl acetate, single-component self-drying epoxy resin, melamine, ammonium polyphosphate, pentaerythritol, recyclable materials and pigments into a container, stirring at 400-600 r / min for 20-30 min, spraying into a mold, air-drying, and then entering a crushing and screening process to obtain polygonal microporous fireproof, heat-insulating and sound-insulating particles with a particle size of 0.1-7 mm.

[0012] This application describes a polygonal microporous fireproof, heat-insulating, and sound-absorbing granule obtained by mixing vinyl acetate, a single-component self-drying epoxy resin, melamine, ammonium polyphosphate, pentaerythritol, recyclable materials, and pigments. Applying this granule to decorative surfaces enhances their sound insulation and fireproofing properties. The blending of vinyl acetate with epoxy resin and pigments adjusts the viscosity, flowability, and drying speed of the epoxy resin, improving its coating effect and thus enhancing the fireproof, heat-insulating, and thermal insulation performance of the decorative panel. Melamine, ammonium polyphosphate, pentaerythritol, and recyclable materials form a flame-retardant system that synergistically combines the effects of intumescent flame retardants and physical flame retardants. Furthermore, the addition of recyclable materials results in polygonal microporous fireproof, heat-insulating, and sound-absorbing granules, which improve the wear resistance of the decorative surface.

[0013] In some embodiments, the recyclable material is one or more of silicate white cement, fly ash, and construction or industrial solid waste powder particles.

[0014] Preferably, the recyclable material is silicate white cement.

[0015] In some embodiments, the pigment is a coating-grade Schott pigment.

[0016] Schott pigments exhibit good compatibility with various materials used in the preparation of polygonal microporous fireproof, heat-insulating, and sound-absorbing particles and are unaffected by sunlight, chemicals, and heat. They can withstand temperatures up to 700℃. Furthermore, Schott pigments are highly inert and do not easily migrate from decorative surfaces, thus ensuring durable decorative effects and high-temperature resistance. Schott pigments also possess excellent infrared refraction properties, further enhancing the infrared refraction of decorative surfaces.

[0017] In some embodiments, the multifunctional decorative particles, by weight, comprise the following raw materials: 25-45 parts modified fluorosilicone resin, 0.5-1.5 parts drying agent, 7-11 parts environmentally friendly diluent, 15-20 parts rutile titanium dioxide, 8-12 parts infrared refractive material, 0.5-1.5 parts fumed silica, and 25-30 parts silicon powder.

[0018] In some embodiments, the infrared refractive material is one or more of calcium fluoride, zinc sulfide, zinc selenide, zirconium dioxide, hafnium dioxide, and tantalum pentoxide.

[0019] In some embodiments, the environmentally friendly diluent is dimethyl carbonate or propylene glycol monomethyl ether.

[0020] In some embodiments, the preparation method of the multifunctional decorative particles includes the following steps: adding modified fluorosilicone resin, drying agent, environmentally friendly diluent, rutile titanium dioxide, infrared refractive material, fumed silica, and silicon powder into a container, stirring at 600-800 r / min for 20-30 min, spraying the mixture onto the surface of polygonal microporous fireproof, heat-insulating, and sound-insulating particles, stirring for 20-30 min, then subjecting the mixture to high-pressure blowing, hot air drying, and a continuous process of specification screening to obtain multifunctional decorative particles with particle sizes of 0.5-8 mm.

[0021] In some embodiments, the method for preparing the modified fluorosilicone resin includes the following steps:

[0022] A1. Add octamethylcyclotetrasiloxane, hydrogen-containing double-ended head, trifluoropropylmethyldimethoxysilane, and concentrated sulfuric acid to a reaction vessel and react at 45-65℃ for 7-9 hours. Add sodium carbonate and stir for 35 hours to obtain fluorinated hydrogen-terminated silicone oil.

[0023] A2. Mix the fluorinated hydrogen-terminated silicone oil obtained in step A1 with chloroplatinic acid and allyl glycidyl ether, and react at 120-160℃ for 3-6 hours to obtain fluorinated epoxy silicone oil.

[0024] A3. Mix the fluorinated terminal epoxy silicone oil obtained in step A2 with the terminal amino polyether and react at 80-130℃ for 8-12h to obtain fluorinated amino silicone oil.

[0025] A4. Mix the fluorinated amino silicone oil obtained in step A3 with HDI trimer and react at 80-110℃ for 2-4 hours to obtain modified fluorosilicone resin.

[0026] Preferably, the mass ratio of the octamethylcyclotetrasiloxane, the hydrogen-containing double-ended head, and the trifluoropropylmethyldimethoxysilane is (6-8):1:(15-20).

[0027] This application prepares multifunctional decorative particles by coating rutile titanium dioxide, infrared refractive materials, fumed silica, and silicon powder with modified fluorosilicone resin. The modified fluorosilicone resin has good affinity with fluorosilicone resin, which makes the multifunctional decorative particles less likely to precipitate from the decorative surface during application, thus improving the flame retardant, wear-resistant, heat-resistant, and infrared refractive properties of the decorative surface. This application further modifies the fluorosilicone resin. On the one hand, introducing polyether segments into the shell of the multifunctional decorative particles improves their tactile feel; on the other hand, introducing polyurethane segments into the fluorosilicone resin further enhances the waterproof and mechanical properties of the decorative surface.

[0028] In some embodiments, the mass ratio of the fluorinated hydrogen-terminated silicone oil to allyl glycidyl ether in step A2 is 1:(0.05-0.15); the mass ratio of the fluorinated epoxy silicone oil to amino-terminated polyether in step A3 is 1:(0.03-0.05); and the mass ratio of the fluorinated amino silicone oil to HDI trimer in step A4 is 1:(0.03-0.06).

[0029] This application, by limiting the ratio of fluorinated hydrogen-terminated silicone oil to allyl glycidyl ether, fluorinated epoxy silicone oil to amino-terminated polyether, and fluorinated amino silicone oil to HDI trimer, can make the multifunctional decorative particles contain unreacted -NCO groups, which can react with the epoxy groups on the polygonal microporous fireproof, heat-insulating and sound-insulating particles. This can further prevent the multifunctional decorative particles from falling off and is beneficial to improving the flame retardant properties, wear resistance, mechanical properties, heat resistance and infrared refraction effect of the decorative surface.

[0030] Another aspect of the present invention provides a method for preparing an anti-slip and cooling granular decorative surface, comprising the following steps:

[0031] S1. Apply polysiloxane primer to the substrate surface by brushing and dry to obtain the primer;

[0032] S2. Apply a portion of the fluorosilicone resin to the surface of the primer obtained in step S1 to obtain the first wet adhesive layer.

[0033] S3. Spray a portion of polygonal microporous fireproof, heat-insulating and sound-insulating particles onto the surface of the first undried adhesive layer obtained in step S2. After 4-8 hours, clean and collect the unadhesive polygonal microporous fireproof, heat-insulating and sound-insulating particles for later use, thus obtaining the first anti-slip particle layer.

[0034] S4. Apply a portion of fluorosilicone resin to the first anti-slip particle layer obtained in step S3 to obtain the second wet adhesive layer.

[0035] S5. Spray the remaining amount of polygonal microporous fireproof, heat-insulating and sound-insulating particles onto the second uncured adhesive layer obtained in step S4. After 4-8 hours, clean up the unadhesive polygonal microporous fireproof, heat-insulating and sound-insulating particles to obtain the second anti-slip particle layer.

[0036] S6. After polishing the second granular layer obtained in step S5 with a resin polishing pad, spray multifunctional decorative particles, polish it a second time after 20-26 hours, then brush on the remaining amount of fluorosilicone resin, and dry it to obtain the final product.

[0037] Preferably, the secondary polishing operation method is as follows: polishing is performed sequentially using resin polishing pads with mesh sizes of 300, 600, and 1000 respectively.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The non-slip and cooling particle decorative surface prepared by the present invention using polygonal microporous fireproof, heat-insulating and sound-insulating particles, multifunctional decorative particles, polysiloxane and fluorosilicone resin as raw materials has the characteristics of long service life, good decoration and good mildew prevention effect, and has excellent pressure resistance, wear resistance, waterproof and breathable performance and UV resistance. It can simultaneously meet the anti-slip and polishing effects and can be reused.

[0040] (2) This invention obtains a polygonal microporous fireproof, heat-insulating, and sound-insulating particle by mixing vinyl acetate, a single-component self-drying epoxy resin, melamine, ammonium polyphosphate, pentaerythritol, recyclable materials, and pigments. When used on decorative surfaces, this particle enhances the sound insulation and fireproofing effects. The flame-retardant system composed of melamine, ammonium polyphosphate, pentaerythritol, and recyclable materials synergistically combines the effects of intumescent flame retardants and physical flame retardants. Furthermore, the addition of recyclable materials results in polygonal microporous fireproof, heat-insulating, and sound-insulating particles, which improve the wear resistance of the decorative surface.

[0041] (3) The present invention prepares multifunctional decorative particles by coating rutile titanium dioxide, infrared refractive material, fumed silica and silicon powder with modified fluorosilicone resin, which is beneficial to improve the wear resistance, heat resistance and infrared refraction effect of the decorative surface. Furthermore, the fluorosilicone resin is modified. On the one hand, the introduction of polyether segments on the shell of the multifunctional decorative particles can improve the tactile feel of the multifunctional decorative particles. On the other hand, the introduction of polyurethane segments on the fluorosilicone resin can further improve the waterproof performance of the decorative surface. Detailed Implementation

[0111] Performance testing

[0112] Performance tests were conducted on the anti-slip and heat-reducing particle decorative surfaces obtained in the above embodiments and comparative examples:

[0113] (1) Heat resistance: The original tensile strength of each anti-slip and cooling particle decorative surface was tested according to GB / T 1040.1-2006. Then, the tensile strength of each anti-slip and cooling particle decorative surface was tested after heat treatment at 80℃ for 168h.

[0114] (2) Water resistance: The water permeability of each anti-slip and cooling particle decorative surface was tested after 2 hours of water pressure of 0.5 MPa.

[0115] (3) Abrasion Resistance Test: Each plate was prepared with anti-slip and cooling granular decorative surfaces according to MIL-PRF-24667C on a 300×150×3mm steel test plate. Each plate was abraded for 50 cycles in a cable abrasion tester, and its mass was measured. Then, each plate was abraded for another 450 cycles in the cable abrasion tester. For the abrasion coating, the wire in the cable abrasion tester was replaced after the first 50 cycles and every 150 cycles thereafter. After abrasion was completed, the final coating mass was obtained. The percentage of mass loss was calculated as follows:

[0116] Mass loss % = 100 × (M2 - M3) / (M2 - M1), where M1 is the mass of the board before coating, M2 is the mass after 50 cycles, and M3 is the mass at the end of the test.

[0117] (4) Flame retardant performance: The flame retardant rating of each anti-slip and cooling particle decorative surface was tested under the UL 94 test standard. The coefficient of thermal expansion of each anti-slip and cooling particle decorative surface was characterized using a TMA Q400 thermomechanical analyzer under a nitrogen atmosphere, with a temperature range of 100-200℃, a fixed load of 0.05N, and a heating rate of 5℃ / min.

[0118] (5) Infrared refraction effect: The infrared heating lamp used to heat each anti-slip and cooling particle decorative surface is 50mm. The focal length of the lamp is 50mm and the minimum spot diameter of the focal point is 20mm. After heating for 30 minutes, the temperature of each decorative surface is tested using a 572-2 infrared thermometer.

[0119] The test results are shown in Table 1:

[0120] Table 1

[0121]

[0122] As shown in Table 1, the anti-slip and cooling particle decorative surfaces in Examples 1-3 of this invention have good mechanical properties, heat resistance, flame retardancy, water resistance, and infrared refraction. A comparison between Example 4 and Example 1 shows that replacing the Schott pigment with ordinary pigment reduces the infrared refraction of the decorative surface. A comparison between Example 5 and Example 1 shows that not adding recyclable materials reduces the flame retardancy and wear resistance of the decorative surface. A comparison between Examples 6-8 and Example 1 shows that changing the ratio of fluorinated hydrogen-terminated silicone oil to allyl glycidyl ether, fluorinated epoxy silicone oil to amino-terminated polyether, and fluorinated amino silicone oil to HDI trimer prevents the multifunctional decorative particles from reacting with the epoxy groups on the polygonal microporous fireproof, heat-insulating, and sound-insulating particles, making the decorative particles prone to detachment and reducing the flame retardancy, mechanical properties, wear resistance, water resistance, heat resistance, and infrared refraction of the decorative surface. A comparison between Example 9 and Example 1 shows that directly using fluorosilicone resin to prepare multifunctional decorative particles deteriorates the heat and water resistance, flame retardancy, wear resistance, and infrared refraction of the decorative surface.
