Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to a cold-pressed jadeite artificial quartz slab and its preparation method. Background Technology

[0002] Cold-jade marble, originating from Yunnan, my country, is a natural jade-like stone. Its main color combination is black, white, and green, evenly distributed. Due to its serene and understated, stable and simple appearance, it exudes an alluring jade-like texture and a noble and mysterious charm, making it very popular since its market launch and selling well both domestically and internationally. However, as the raw resources of cold-jade marble continue to dwindle, its production is constantly decreasing. Coupled with the rising popularity of green trends in China, the price of cold-jade marble has skyrocketed, making it unaffordable for many consumers.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0015] S9. Quartz stone slab blanks are formed by vibration pressing with a pressing device under vacuum conditions;

[0016] S10. The quartz slab blank formed by vibration pressing is fed into the curing equipment for heat curing;

[0017] S11. After curing, let it cool completely at room temperature before it is put into a thickness calibrating machine for thickness determination, and then polished by a water grinding and polishing equipment.

[0018] Both component A and component B include 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz powder, unsaturated polyester resin, silane coupling agent, and curing agent, and component B also includes black pigment.

[0019] Furthermore, in step S3, after the block A material pressed and formed in step S2 is covered on the block area by the glue plate, each block A material is sprinkled with dry powder with a fineness greater than or equal to 100 mesh; the amount of the dry powder is 0.5 parts by weight, and the dry powder includes black pigment and 200 mesh quartz powder, wherein the ratio of black pigment and 200 mesh quartz powder by weight is (0.02~0.03):(99.97~99.98).

[0020] Furthermore, in step S5, 0.3 parts by weight of material B are sprinkled on material A.

[0021] Furthermore, in step S7, after material B fills the gap between the block material A and the strip material A, material B is also sprinkled on the block material A and the strip material A. In step S7, the amount of material B is 10 parts by weight.

[0022] Furthermore, the A material also includes titanium dioxide, and the weight ratio of 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz powder, unsaturated resin, curing agent, silane coupling agent, and titanium dioxide in the A material is (15-25):(27-37):(25-35):(10-20):(0.1-0.2):(0.09-0.18):(0.35-0.45).

[0023] In the B material, the weight ratio of 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz powder, unsaturated resin, curing agent, silane coupling agent, and black pigment is (15-25):(30-40):(25-35):(10-20):(0.1-0.2):(0.09-0.18):(0.35-0.45).

[0024] Furthermore, the gray base slurry comprises unsaturated resin, curing agent, silane coupling agent, yellow pigment, black pigment, and 200-mesh quartz powder, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, yellow pigment, black pigment, and 200-mesh quartz powder in the gray base slurry is (99.978~99.989):1:0.9:(0.001~0.002):(0.01~0.02):67.93;

[0025] The green pigment paste comprises unsaturated resin, curing agent, silane coupling agent, titanium dioxide, yellow pigment, and green pigment, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, titanium dioxide, yellow pigment, and green pigment in the green pigment paste is 100:1:0.9:(0.15~0.25):(0.04~0.05):(0.4~0.5).

[0026] The gray pigment paste includes unsaturated resin, curing agent, silane coupling agent, and black pigment, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, and black pigment in the gray pigment paste is 100:1:0.9:(0.3~0.4).

[0028] Furthermore, in the gray base slurry, the quartz powder accounts for 40% of the total weight of the gray base slurry.

[0029] Furthermore, in step S2, the vacuum degree is -0.1 MPa, the vibration frequency is 30-35 Hz, and the time is 30-90 s. In step S9, the vacuum degree is -0.1 MPa, the vibration frequency is 30-45 Hz, and the time is 60-120 s.

[0030] Furthermore, in step S10, the thermosetting parameters are: curing at a temperature of 90–110°C for 90–120 min.

[0032] Beneficial effects:

[0033] This invention provides a cold-jadeite artificial quartz slab and its preparation method. By adjusting the material distribution process of material A, and combining it with new pressing methods and the application of various color pastes to material A, an artificial quartz slab with a cold-jadeite marble pattern is obtained. Compared with existing artificial quartz slab products, the quartz slab produced by this invention has irregular marble textures and flowing textures in various shades such as black, green, and yellow, thus replicating the appearance of cold-jadeite marble and solving the problem of low production volume of cold-jadeite marble, which makes it difficult to meet market demand.

[0034] Furthermore, this invention introduces black B material during the preparation of artificial quartz stone and fills the gaps between the block-shaped A material and strip-shaped A material pressed by the pressing equipment and the press machine, thereby giving the surface of the cold jade artificial quartz stone slab a clearer texture.

[0052] This invention provides a cold-pressed jadeite artificial quartz slab and its preparation method. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0053] A method for preparing a cold-pressed jadeite artificial quartz slab, wherein the cold-pressed jadeite artificial quartz slab comprises material A and material B; both material A and material B comprise 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz powder, unsaturated polyester resin, silane coupling agent, and curing agent, and material B further comprises black pigment, while material A is white; the preparation method includes the following steps:

[0054] S1. Lay a high-temperature film inside the first mold frame to prevent the material from adhering to the first mold frame, then lay 85 to 95 parts by weight of material A inside the entire first mold frame, then pour 0.5 to 1.5 parts by weight of gray base slurry on material A, and after pouring the gray base slurry, cover material A with a high-temperature film and cover it with a wooden board for thickness determination.

[0055] S2. After step S1 is completed, the laid-out material A is vibrated and pressed into shape under vacuum conditions using a pressing device. Specifically, the process parameters for vibration pressing are: vacuum degree -0.1 MPa, vibration frequency 30-35 Hz, and time 30-90 s. After vibration pressing, block-shaped material A with a marble texture (e.g., ...) can be obtained. Figure 1 (as shown);

[0056] S3. Lay kraft paper inside the second mold frame 11, draw several irregular block areas on the kraft paper using a projection device, and then cover the block A material pressed and formed in step S2 onto the block areas using a glue plate.

[0057] S4. Take 15-25 parts by weight of material A and lay it on the anti-sticking film. Then, apply 0.15-0.2 parts by weight of green pigment, 0.05-0.1 parts by weight of gray pigment, and 0.03-0.06 parts by weight of yellow pigment respectively. Next, press material A into strips using a pressing machine, so that the pressed strips of material A have flow patterns of various shades such as yellow, green, black, and gray (e.g., Figure 2 (as shown);

[0058] S5. Take 45-55 parts by weight of material A and lay it on the anti-sticking film. Then, pour on 0.3-0.4 parts by weight of green pigment and 0.2-0.25 parts by weight of gray pigment respectively. Next, press material A into strips using a pressing machine, so that the pressed strips of material A have flow patterns of various shades such as green, black, and gray (e.g., Figure 3 (as shown);

[0059] S6. Fill the spaces between the block-shaped sections with the strip-shaped A material pressed out in steps S4 and S5. This combination of the strip-shaped A material and the block-shaped A material results in an artificial quartz slab surface that possesses both marble-like textures and flowing patterns in various shades of black, green, and yellow (e.g., Figure 4 (Part A), thus the artificial quartz slab produced has the appearance of cold jade marble;

[0060] S7. After step S6 is completed, fill the gap between the block A material and the strip A material with material B to make the artificial quartz stone slab have a clearer texture.

[0061] S8. After step S7 is completed, lay 155 to 185 parts by weight of material A so that the thickness of the sheet after vibration pressing can meet the production requirements.

[0062] S9. Quartz stone slab blanks are formed by vibration pressing under vacuum conditions. Specifically, the process parameters for vibration pressing are: vacuum degree -0.1Mpa, vibration frequency 30~45Hz, and time 60~120s.

[0063] S10. The vibratory pressing quartz slab blank is fed into the curing equipment for heat curing. Specifically, the heat curing parameters are: curing at a temperature of 90-110℃ for 90-120 minutes.

[0064] S11. After curing, the material is placed at room temperature until it is completely cooled before being sized by a thickness sizing machine. Then it is polished by a water polishing machine to obtain cold jade artificial quartz stone slabs.

[0065] Furthermore, in step S3, after the block A material pressed and formed in step S2 is covered on the block area using a glue plate, each block A material is sprinkled with dry powder with a fineness greater than or equal to 100 mesh. The amount of the dry powder is 0.5 parts by weight, and the dry powder includes black pigment and 200-mesh quartz powder, wherein the ratio of black pigment to 200-mesh quartz powder by weight is (0.02~0.03):(99.97~99.98). By sprinkling dry powder with a fineness greater than or equal to 100 mesh onto the block A material, the dry powder can be evenly sprinkled on the block A material, and the dry powder can penetrate into the material during the preparation of the artificial quartz stone slab, making the surface of the artificial quartz stone slab have a strong sense of layering. In addition, by adding quartz stone powder to the dry powder, it is possible to avoid the black pigment from becoming too dark, ensuring that the surface of the artificial quartz stone slab has a subtle sense of layering.

[0066] Furthermore, in step S5, 0.3 parts by weight of material B are sprinkled on material A. This makes the black texture more prominent and obvious in the areas with flowing texture on the surface of the artificial quartz stone slab, and better matches the appearance of cold jade marble.

[0067] Furthermore, in step S7, after material B fills the gap between the block-shaped material A and the strip-shaped material A, material B is also sprinkled onto the block-shaped material A and the strip-shaped material A. In step S7, the amount of material B used is 10 parts by weight. By sprinkling material B onto the block-shaped material A and the strip-shaped material A, not only can the surface of the artificial quartz stone slab have a clearer texture, but also during the preparation of the artificial quartz stone slab, material B will seep into material A, so that after polishing, the surface of the artificial quartz stone slab can form an ink-wash style with varying shades.

[0068] Furthermore, the A material also includes titanium dioxide. By adding titanium dioxide to the A material, the whiteness of the unpatterned areas on the surface of the artificial quartz slab can be improved, thereby highlighting the texture and enhancing the natural effect of the texture.

[0069] Furthermore, in order to make the prepared artificial quartz stone slab have good density and high hardness, the proportion of 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz stone powder, unsaturated resin, curing agent, silane coupling agent and titanium dioxide in the A material is (15-25):(27-37):(25-35):(10-20):(0.1-0.2):(0.09-0.18):(0.35-0.45) by weight.

[0070] Furthermore, in the B material, the weight ratio of 40-70 mesh quartz sand, 70-120 mesh quartz sand, 300 mesh quartz powder, unsaturated resin, curing agent, silane coupling agent, and black pigment is (15-25):(30-40):(25-35):(10-20):(0.1-0.2):(0.09-0.18):(0.35-0.45). By making the composition of the B material similar to that of the A material, during the preparation of the artificial quartz slab, the B material filling the space between the block-shaped and strip-shaped A materials can be fully cured and bonded to the A material, thereby ensuring that a clear texture can be formed between the block-shaped and strip-shaped A materials.

[0071] Furthermore, the gray base slurry also includes quartz powder. Quartz powder can adjust the viscosity of the gray base slurry. When quartz powder accounts for 40% of the total weight of the gray base slurry, the viscosity of the gray base slurry is suitable, thereby preventing the gray base slurry from seeping into material A. After material A is pressed, a marble texture with clear layers and good three-dimensionality can be formed on the block material A.

[0072] Furthermore, the gray base slurry comprises unsaturated resin, curing agent, silane coupling agent, yellow pigment, black pigment, and 200-mesh quartz powder, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, yellow pigment, black pigment, and 200-mesh quartz powder in the gray base slurry is (99.978~99.989):1:0.9:(0.001~0.002):(0.01~0.02):67.93;

[0073] The green pigment paste comprises unsaturated resin, curing agent, silane coupling agent, titanium dioxide, yellow pigment, and green pigment, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, titanium dioxide, yellow pigment, and green pigment in the green pigment paste is 100:1:0.9:(0.15~0.25):(0.04~0.05):(0.4~0.5).

[0074] The gray pigment paste includes unsaturated resin, curing agent, silane coupling agent, and black pigment, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, and black pigment in the gray pigment paste is 100:1:0.9:(0.3~0.4).

[0075] The yellow color paste includes unsaturated resin, curing agent, silane coupling agent, titanium dioxide, and yellow pigment, and the weight ratio of unsaturated resin, curing agent, silane coupling agent, titanium dioxide, and yellow pigment in the yellow color paste is 100:1:0.9:(0.2~0.3):(0.3~0.4).

[0076] In the aforementioned gray base color paste, green color paste, gray color paste, and yellow color paste, the proportion of unsaturated resin, curing agent, and silane coupling agent is higher than that of pigment. This allows the color paste and material A to easily bond during the preparation of artificial quartz slabs, ensuring the formation of the texture. This invention, by introducing one or more pigments into the color paste for formulation, enables the resulting artificial quartz slab to most closely resemble the appearance of cold-cut jade marble.

[0077] Specifically, the yellow pigment in this invention can be iron yellow; the black pigment can be one or both of iron black and carbon black; the green pigment can be chrome green; the unsaturated resin can be one of epoxy resin, phenolic resin, acrylic resin and polyurethane resin; the silane coupling agent can be one of vinyltriethoxysilane, vinyltrimethoxysilane, γ-aminopropyltriethoxysilane, anilinemethyltriethoxysilane, γ-chloropropyltriethoxysilane or methacryloxypropyltrimethoxysilane; and the curing agent can be one or more of methyl ethyl ketone peroxide, cyclohexanone peroxide, tert-butyl peroxide-2-ethylhexanoate and tert-butyl peroxide.

[0078] like Figure 5 , Figure 8 and Figure 10 As shown, further, in step S3, the projection device includes a support 1; and also includes:

[0079] The projection box 5 has an opening at its bottom and is movably suspended on the bracket 1.

[0080] The light-transmitting plate 2 is provided with a non-transmitting area 202 and a light-transmitting area 201 corresponding to the block area, and the light-transmitting plate 2 is horizontally arranged in the projection box 5.

[0081] Light source 3, which may be a lamp tube, is fixed inside the projection box 5 and located above the light-transmitting plate 2;

[0082] The drive component 4 is fixed on the bracket 1 and is used to drive the projection box 5 to move up and down.

[0083] The projection box 5 is positioned above the conveying device 10, which has forward and reverse conveying functions. Multiple conveying devices 10 can be provided and arranged on the same straight line to convey the first mold frame and the second mold frame 11. In this way, step S3 can be performed simultaneously with other steps without affecting production efficiency.

[0084] Black tape can be applied to the non-transparent area 202 so that the light emitted by the lamp source 3 can only shine onto the kraft paper through the transparent area 201. Since the transparent area 201 corresponds to the shape of the block area to be drawn on the kraft paper, the light emitted by the lamp source 3 can form the shape of the block area on the kraft paper after shining on it, which makes it easier for production personnel to draw several irregular block areas on the kraft paper.

[0085] like Figure 8 and Figure 9 As shown, the projection device further includes a support plate 6; the support plate 6 is arranged parallel to the two inner walls of the projection box 5, and the support plate 6 is used to support the light-transmitting plate 2.

[0086] like Figure 10 As shown, further, one side of the projection box 5 is provided with an insertion port 51 for the light-transmitting plate 2 to be horizontally inserted into the projection box 5. The light-transmitting plate 2 is connected to a pull rod 12. The pull rod 12 and the insertion port 51 facilitate the production personnel to replace the light-transmitting plate 2. This allows for the pre-design of different patterns for artificial quartz stone slabs, thereby enriching the patterns on the surface of similar products.

[0087] like Figure 5 and Figure 6 As shown, further, the driving component 4 includes:

[0088] A dual-output shaft geared motor 41 is fixedly mounted on the bracket 1.

[0089] The transmission rod 42 has two parts, and the two transmission rods 42 are respectively connected to the two output shafts of the dual output shaft reduction motor 41;

[0090] The suspension rope 43 has at least two ropes, and the ropes 43 can be wound onto the two transmission rods 42 respectively.

[0091] By setting transmission rods 42 on both sides of the dual-output shaft geared motor 41 and setting hanging ropes 43 that can be wound onto the two transmission rods 42 respectively, it is ensured that the projection box 5 can move up or down, thereby facilitating the production personnel to replace the light-transmitting plate 2.

[0092] like Figure 6As shown, the projection device further includes multiple guide rods 7 fixed on the support 1. The two sides of the projection box 5 are movably connected to the guide rods 7, so that the projection box 5 can maintain balance when moving up and down, thereby ensuring that the shape of the block area can be correctly projected onto the kraft paper, providing a guarantee for subsequent normal production.

[0093] like Figure 6 and Figure 7 As shown, the projection device further includes:

[0094] Limit switch 8 is mounted on guide rod 7 and is used to detect the top of projection box 5;

[0095] The controller is electrically connected to the limit switch 8.

[0096] The limit switch 8 can be a roller-type limit switch 8. When the projection box 5 moves upward and is detected by the limit switch 8, the controller controls the drive component 4 to stop running, so that the projection box 5 can be kept at the required height. When the projection box 5 is working at this height, the size of the block area projected onto the kraft paper is basically the same as the actual size of the block area to be drawn on the kraft paper.

[0097] like Figure 8 and Figure 9 As shown, the projection device further includes an infrared emitter 9, which is provided in multiple forms and is fixed to the bottom of the support plate 6 for positioning the kraft paper so that production personnel can accurately place the kraft paper into the second mold frame 11.

[0098] The present invention also provides a cold jadeite artificial quartz slab, which is prepared by the aforementioned method for preparing cold jadeite artificial quartz slabs. The quartz slab has irregular marble textures and flowing textures in various shades such as black, green, and yellow on its surface, thereby imitating the appearance of cold jadeite marble and solving the problem of low production of cold jadeite marble which makes it difficult to meet market demand.
