Abstract

The application discloses a ground stone material traceless polishing and color locking glaze integrated construction method, and belongs to the technical field of construction methods. The method breaks the traditional process logic of paving first and then filling the joints, and sequentially comprises five steps of base joint gap fine processing, deep layer color adjusting and filling, overall rough grinding and leveling, overall permeation and coloring, and thermal physical glaze crystallization and color locking. The color adjusting and filling of the joints and the overall polishing and leveling are completed first, then the stone is overall colored, and finally, the transparent crystalline glaze layer with Mohs hardness greater than or equal to 6 is formed on the surface through frictional heat crystallization. The color of the stone and the joints is jointly closed below the glaze layer, the visual traceless fusion of the joints and the body of the stone is realized, the color durability is greatly improved due to the under-glaze color locking structure, and the stone has excellent properties of high wear resistance, water resistance and stain resistance. The industry pain points of the traditional stone joint color difference, surface dyeing color fading and joint dirt accumulation are solved.

Description

Technical Field

[0001] A method for seamless polishing, color locking, and glazing of floor stone is disclosed. This invention belongs to the technical field of construction methods, specifically relating to a method for seamless polishing, color locking, and glazing of floor stone. Background Technology

[0002] In stone flooring projects, traditional construction techniques generally follow a "lay first, then grout" sequence, meaning the stone is laid first, then the grout is filled, and finally the surface is crystallized and polished. This type of process has the following significant drawbacks: The gaps and the color difference between the gaps and the stone itself are obvious, and the lines of the grout are abrupt, failing to achieve a "seamless" visual effect and seriously affecting the overall decorative effect of the stone floor; Stone staining and color repair are mostly done on the surface. The color only adheres to or lightly penetrates the surface layer of the stone. During subsequent use, it is very easy to fade and change color after wear and cleaning, resulting in poor durability. The grout material and the stone surface are treated separately, resulting in a discontinuous protective layer. The gaps are prone to dirt accumulation, blackening, and peeling, leading to high maintenance costs in the later stages. Existing stone dyeing and color fixing technologies are mostly designed for raw quarry blocks or single stone slabs. They lack a systematic process for seamless treatment of the "gaps-overall surface" of the paved floor, making it impossible to achieve complete sealing of color and protective layer. Summary of the Invention

[0003] The technical problem to be solved by this invention is to overcome the existing defects and provide an integrated construction method for seamless grinding, color locking and glazing of ground stone. It breaks the traditional process logic of "laying first and then filling the gaps". Through the integrated process of "first color matching and filling the gaps, then overall coloring, and finally glazing and locking the color", it achieves seamless visual integration between the gaps and the stone. At the same time, it seals the color under the transparent crystalline glaze layer, which greatly improves the color durability and surface wear resistance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A method for seamless polishing, color locking, and glazing of floor stone, comprising the following steps: S1 Base Gap Treatment: After the stone is laid, clean the stone gaps to the set depth, clean the gaps and the two sides of the surface, and let them dry to obtain a clean gap base to be filled. S2 Deep Color Tinting and Filling: High-penetration stone adhesive is used as the filler base material, and nano-level oil-based colorant is added for on-site color tinting, so that the color of the filler matches the base color of the stone ≥95%; the tinted filler is filled into the gap, with the filling surface slightly higher than the stone surface, and after the filler is completely cured, the base surface to be ground is obtained. S3 Overall Rough Grinding and Leveling: Using a stone water grinding equipment with resin grinding discs of progressively smaller grits, the entire stone after grouting is ground to remove the filler material that protrudes above the stone surface, until the gaps and the stone surface are at the same level, resulting in a flat base surface to be colored. S4 Overall Penetration Coloring: High-penetration oil-based dye is mixed with a thinner to achieve the target color. Multiple coats are applied to the entire surface of the stone using spraying equipment to ensure that the overall color of the stone matches the standard color by ≥95%, resulting in a uniformly colored stone surface. S5 Thermal Physical Glazing and Color Locking: Using heavy-duty stone mirror equipment, along with polishing media and crystallizing mirror agent, physical glazing and crystallization are carried out by friction to generate heat on the colored stone surface. A transparent crystalline glaze layer with a Mohs hardness of ≥6 is formed on the stone surface, sealing the color on the stone surface and in the crevices within the glaze layer, thus completing the seamless color locking and glazing construction.

[0005] As a preferred technical solution of the present invention, in step S1, an industrial vacuum cleaner is used in conjunction with a grout cleaning tool to clean the gap to a depth of 3-5mm, and alcohol is used to wipe both sides of the gap to remove oil and dust. The gap and stone surface are then dried until there is no moisture or dust residue.

[0006] As a preferred technical solution of the present invention, in step S2, the filler base material is a highly permeable marble adhesive, and the filler material is 0.4-0.6mm higher than the surface of the stone after filling; the hardness of the filler material after curing is lower than the hardness of the stone body, so as to match the coefficient of thermal expansion of the stone and avoid cracking of the glaze layer or the edge of the stone due to thermal expansion and contraction.

[0007] As a preferred technical solution of the present invention, in step S3, the resin grinding disc grinds the stone step by step from coarse to fine, until the particle size is 3-4. If pinhole defects are found on the stone surface during the grinding process, they are repaired with diluted glue of the same batch color. Ordinary marble glue is prohibited from being used for backfilling to avoid patch-like color differences.

[0008] As a preferred technical solution of the present invention, in step S4, the spraying equipment is an electric air compressor with a spray gun; during spraying, the number of spraying passes is adjusted according to the depth of the stone, with more spraying passes for light-colored stone and fewer spraying passes for dark-colored stone. After spraying, the stone color is slightly darker than the standard dark stone, and after the color stabilizes, it is consistent with the standard color.

[0009] As a preferred technical solution of the present invention, in step S5, the polishing medium is a scouring pad or steel wool; the crystallizing mirror agent reacts with the surface of the stone under the condition of frictional heating to form a glassy crystalline glaze layer, while sealing the color of the dye and gap filler that have penetrated into the stone inside the glaze layer.

[0010] As a preferred technical solution of the present invention, the construction environment temperature is controlled at 15-30℃ and the relative humidity is less than 70% to avoid the transparent glaze layer from turning white due to efflorescence in a humid environment, and to ensure that the glaze layer is transparent and has no color difference.

[0011] As a preferred technical solution of the present invention, the construction method is applicable to the integrated surface treatment after the laying of natural marble, granite, slab rock, and terrazzo precast panels.

[0012] Compared with existing technologies, the beneficial effects of this invention are: breaking the traditional sequence of "laying first, then filling the gaps", first color matching and filling the gaps, then overall polishing, coloring, and glazing, so that the gap color is completely integrated with the stone body, visually eliminating the gap boundary and achieving a "seamless and integrated" decorative effect, solving the industry pain point of abrupt color difference in traditional grouting.

[0013] By forming a dense and transparent glassy glaze layer through surface crystallization and glazing, all the colors of stone staining and grout coloring are sealed under the glaze layer, avoiding damage to the color from daily wear, cleaning, and ultraviolet rays. The color-locking life is 3-5 times that of traditional surface staining.

[0014] The crystalline glaze layer has a Mohs hardness of 6 or higher, and features high gloss, waterproof, stain-resistant, and wear-resistant properties. The protective layer continuously covers the stone and gaps, preventing dirt accumulation, blackening, and peeling in the gaps, and significantly reducing the cost of later maintenance.

[0015] By controlling key details such as zero-dust substrate treatment, expansion coefficient matching, temperature and humidity control, and standardized pinhole repair, common quality problems such as glaze cracking, efflorescence, and color difference patches are effectively avoided, resulting in a high yield and stable performance. Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides a technical solution: Example

[0018] A seamless polishing, color-locking, and glazing method for natural marble floors, specifically including the following steps: S1 Base Gap Treatment: After the marble is laid and reaches its strength, use an industrial vacuum cleaner with a special gap-opening tool to clean the gaps to a depth of 4mm, ensuring that there is no cement residue or dust in the gaps; then use a lint-free cloth dampened with industrial alcohol to wipe a 2cm area on both sides of the gap to thoroughly remove oil and dust, and let it air dry naturally until the gaps and the stone surface are completely dry and free of dust residue, forming a clean gap base.

[0019] S2 Deep Color Tinting and Filling: High-penetration marble adhesive is selected as the filler base material. Nano-grade oil-based colorant is added for on-site color matching and comparison. Multiple color tests are conducted until the filler color matches the marble base color by 96%. The tinted marble adhesive is filled into the gaps, with the filling surface slightly higher than the stone surface by about 0.5mm to offset subsequent grinding losses and material shrinkage. The adhesive is left to stand at room temperature for 24 hours to fully cure, resulting in a grouted base surface ready for grinding. The hardness of the cured filler adhesive is lower than that of the marble itself, matching the stone's coefficient of thermal expansion.

[0020] S3 Overall Coarse Grinding and Leveling: Use a water grinder with stone-specific resin grinding pads, grinding progressively from coarse to fine grit (1 → 2 → 3) to remove excess grout protruding above the stone surface. Grind until the grout lines are completely level with the stone surface; at this point, the grout color has been integrated into the overall stone base. During the grinding process, inspect the stone surface. If any tiny pinhole defects are found, immediately patch them with diluted adhesive of the same batch color. Do not use ordinary marble adhesive for backfilling, as this will create color-matched patches.

[0021] S4 Overall Penetration Coloring: A high-penetration oil-based dye is used with a special thinner to adjust the color to match the standard dark marble color chart. An electric air compressor is used with a spray gun for overall spraying. Multiple coats are applied to light-colored stone areas, while dark areas are lightly sprayed. The final color of the stone is slightly darker than the standard color. After the color has fully penetrated and stabilized, the overall color matches the standard color by more than 95%, forming a uniform and consistent colored surface.

[0022] S5 Thermophysical Sealing and Crystallization Color Locking: Utilizing a heavy-duty stone mirror polishing machine, along with a scouring pad and crystallizing mirror polishing agent, high-speed friction generates heat on the stone surface. Through physical action, the crystallizing agent reacts with the stone surface, forming a dense, transparent, glassy crystalline glaze layer. This glaze layer has a Mohs hardness of 6.2, not only giving the stone a high mirror gloss but also completely sealing the dyes inside the stone and the colorants in the crevices beneath the glaze layer, ultimately achieving a seamless, traceless, and long-lasting color-locking finish.

[0023] In this embodiment, the ambient temperature is controlled at 22-26℃ and the relative humidity at 55%-65% throughout the construction process to prevent efflorescence and whitening of the glaze. After construction, the marble floor has no obvious visual gaps, the overall color is uniform and natural, the glaze gloss is ≥90 degrees, and it has excellent waterproof and stain-resistant properties. Under normal use, the color retention period can reach more than 8 years. Example

[0024] A method for seamless polishing, color locking, and glazing of granite floors, specifically including the following steps: S1 Base Gap Treatment: After the granite is laid, use an industrial vacuum cleaner with a gap opener to clean the gaps to a depth of 5mm. Wipe the sides of the gaps with alcohol to remove oil stains and let them dry until the surface is completely dry and free of impurities.

[0025] S2 Deep Color Tinting and Filling: Using high-penetration stone adhesive as the base material, nano-oil-based colorant is added to adjust the color to match the granite base color by 95%. After filling the gaps, the adhesive surface is 0.5mm higher than the stone surface and left to stand for 24 hours to fully cure. The hardness of the cured adhesive layer is lower than that of the granite, ensuring a match in the coefficient of thermal expansion.

[0026] S3 Overall Rough Grinding and Leveling: Use a water grinder with No. 1-4 resin grinding pads to grind step by step until the gaps are flush with the stone surface; repair pinhole defects with diluted glue of the same batch.

[0027] S4 Overall Penetration Coloring: High-penetration oil-based dyes are used for color matching, and the coating is applied using an air compressor spray gun. Due to the high density of granite, the number of spray coats is appropriately increased to ensure full color penetration. The final overall color is more than 95% consistent with the standard color.

[0028] S5 Thermophysical Glazing and Color Locking: Using a weighted mirror polishing machine with steel wool and a crystallizing mirror polishing agent, friction generates heat to crystallize the glaze, forming a transparent crystalline glaze layer with a Mohs hardness of 6.5, sealing the color under the glaze, and completing the construction.

[0029] In this embodiment, the construction environment temperature is controlled at 18-28℃ and the humidity is below 70%. The finished granite floor has a seamless visual effect, excellent wear resistance and stain resistance, and is suitable for public areas with high traffic.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
