Technical Field

[0001] The invention belongs to the technical field of ridge tile production and processing, and relates to a solid waste reuse type groove tile production process and groove tiles. Background Art

[0002] In the hot and humid south, using tiles to cover the roof of the house can achieve drainage and heat insulation. The tile roof is mainly composed of groove tiles and ridge tiles. The groove tiles mainly play a role in drainage, while the ridge tiles are set between adjacent groove tiles, thereby covering the gaps between adjacent groove tiles and draining water to the groove tiles for discharge. At present, groove tiles are usually mainly made of cement and fine sand. After being exposed to rain for a long time, the structural strength is low and the heat insulation effect is poor.

[0003] In addition, with the development of the electronics industry, waste electronic circuit boards, waste copper-clad laminate scraps, etc. have increased significantly. After the metals are extracted, the remaining resin and glass fiber powder becomes a difficult problem to deal with. Summary of the invention

[0007] Weighing the corresponding mass of the raw material;

[0008] Calcine silica ash at high temperature to obtain expanded silica ash, mix and stir carbon nanotubes, expanded silica ash and silane coupling agent to obtain a mixture, add the mixture into a fermentation tank containing 7-8% beet oil and 1-2% yogurt by weight of the mixture, and seal and ferment to obtain a modified mixture;

[0009] The modified mixture and all the remaining raw materials are mixed and stirred to form a viscous state;

[0010] Laying the stainless steel fibers in parallel in the mixed raw materials, and using a molding device to press the mixed raw materials into semi-finished groove tiles;

[0011] Baking the semi-finished groove tiles;

[0012] Check whether the semi-finished groove tiles after baking meet the standards. The semi-finished groove tiles that meet the standards proceed to step S6, and the semi-finished groove tiles that do not meet the standards are collected as waste;

[0013] The inspected semi-finished groove tiles are blown to remove dust and glaze;

[0014] The semi-finished tiles after being coated with glaze are baked again to obtain finished groove tiles, which are then inspected and put into storage.

[0015] Furthermore, the sand includes 30-40 parts of medium sand and 30-40 parts of fine sand.

The mixture is added to a fermentation tank with 7-8% beet oil and 1-2% yogurt of the mixture by mass for sealed fermentation to obtain a modified mixture. The vegetable oil and yogurt are fermented together. The microorganisms in the yogurt can be used to decompose the vegetable oil to produce lipophilic ester groups, and the lipophilic ester groups are attached to the surface of the mixed powder under the self-crosslinking action of the microorganisms, thereby improving the compatibility of the mixed powder and the substrate. The carbon nanotubes have a porous structure.

[0029] As described in the background technology, in the hot and humid south, using tiles to cap the roof of a house can achieve drainage and heat insulation. The tile capping is mainly composed of ditch tiles and ridge tiles. The ditch tiles mainly play a role in drainage, while the ridge tiles are set between adjacent ditch tiles, thereby covering the gaps between adjacent ditch tiles and draining water to the ditch tiles for discharge. At present, ditch tiles are usually mainly made of cement and fine sand. After being exposed to rain for a long time, the structural strength is low and the heat insulation effect is poor. In addition, with the development of the electronics industry, waste electronic circuit boards, waste copper clad laminates, etc. have increased significantly. After the metal is extracted, the residual resin glass fiber powder becomes a difficult problem to deal with.

[0030] Based on this, the inventors have created a solid waste reuse type trench tile production process and trench tile of the present application to solve the above-mentioned technical problems.

[0031] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0032] Example

[0033] See also Figure 1In the first aspect, the present invention provides a solid waste reuse type trench tile production process, which uses 60-80 parts (for example, 61 parts, 65 parts, 70 parts, 75 parts, 79 parts) of sand, 30-50 parts (for example, 31 parts, 35 parts, 40 parts, 45 parts, 49 parts) of silica fume, 50-65 parts (for example, 51 parts, 55 parts, 60 parts, 64 parts) of cement, 23-28 parts (for example, 24 parts, 26 parts, 27 parts) of water, 18-25 parts (for example, 19 parts, 22 parts, 24 parts) of resin glass fiber powder, 10-15 parts (for example, 11 parts, 13 parts) of stainless steel fiber, 8-10 parts of carbon nanotubes, 3-5 parts of additives and 1-2 parts of silane coupling agent as raw materials, wherein the stainless steel fibers include at least two and the length of each is 1 / 2 to 4 / 5 of the length of the trench tile. For example, the sand may include 30-40 parts of medium sand and 30-40 parts of fine sand. In this way, the combination of medium sand and fine sand can not only ensure the structural strength of the trench tile, but also improve the waterproof performance. For example, the cement may be Conch 42.5 cement. In this way, the fluidity of Conch cement is good, which can improve the mixing efficiency and thus improve the overall work efficiency. For example, the silane coupling agent may be KH-550.

[0034] The production process comprises the following steps:

[0035] S1. Weigh the corresponding mass of the raw materials. For example, silica fume and resin glass fiber powder can be ground to a target fineness, such as 60-80 mesh, by a ball mill.

[0036] S2, calcining silica ash at high temperature to obtain expanded silica ash, mixing and stirring carbon nanotubes, expanded silica ash and silane coupling agent to obtain a mixture, adding the mixture to a fermentation tank with 7-8% beet oil and 1-2% yogurt of the mixture by mass, and sealing and fermenting to obtain a modified mixture. Here, the mass of the mixture refers to the sum of the masses of the mixture, beet oil and yogurt. Here, the mass of the modified mixture is the sum of the mass of the fermentation product of 2-3% of the sum of the mass of carbon nanotubes, expanded silica ash and silane coupling agent and the mass of the carbon nanotubes, expanded silica ash and silane coupling agent.

[0037] S3, the modified mixture and all the remaining raw materials are mixed and stirred to form a viscous state. Here, the viscosity of the viscous state enables normal molding by molding equipment to be called a semi-finished groove tile.

[0038] S4, laying the stainless steel fibers in parallel in the mixed raw materials, and using a molding device to press the mixed raw materials into semi-finished groove tiles. For example, the stainless steel fibers can be arranged parallel to the length direction of the groove tiles.

[0039] S5, baking the semi-finished groove tiles. For example, before baking, the semi-finished groove tiles can also be inspected to remove products that are not qualified for molding.

[0040] S6, check whether the semi-finished groove tiles after baking meet the standards. The semi-finished groove tiles that meet the standards enter step S6, and the semi-finished groove tiles that do not meet the standards are collected as waste.

[0041] S7. Blow the dust off the inspected semi-finished groove tiles and apply glaze.

[0042] S8, the semi-finished tiles after glazing are baked again to obtain finished groove tiles, and the finished groove tiles are inspected and put into storage.

[0043] In the groove tile production process of the present invention, resin glass fiber powder is used as one of the raw materials, which can effectively solve the problem of difficult treatment of the current resin glass fiber powder. At the same time, the resin glass fiber powder is light in weight, and sand, cement, silica fume and a plurality of stainless steel fibers can effectively improve the overall structural strength. The silica fume is calcined at high temperature to obtain expanded silica fume, and the carbon nanotubes, expanded silica fume and silane coupling agent are mixed and stirred to obtain a mixture. The mixture is added to a fermentation tank with 7-8% beet oil by weight of the mixture and 1-2% yogurt by weight of the mixture for sealed fermentation to obtain a modified mixture. The mixture, vegetable oil and yogurt are fermented together. The microorganisms in the yogurt can be used to decompose the vegetable oil to produce lipophilic ester groups, and the lipophilic ester groups are attached to the surface of the mixed powder under the self-crosslinking action of the microorganisms, thereby improving the compatibility of the mixed powder and the substrate (sand and cement). The carbon nanotubes have a porous structure. Once the light source is irradiated to the surface of the tile, the light can pass through the tightly arranged carbon nanotubes and produce multiple reflections, thereby improving the reflectivity of the tile to heat, thereby effectively improving the thermal insulation performance and solving the problems of low structural strength and poor thermal insulation effect of the existing groove tiles. After practice, the groove tiles have a compressive strength of 20Mpa, a flexural strength of 22Mpa, and a water absorption rate of 1.5%, and the effect is significantly improved.

[0044] In another embodiment, the raw material further comprises nylon fiber filaments, which can effectively enhance the toughness of cement and improve its flexural strength, compressive strength and crack resistance.

[0045] In another embodiment, the additive includes a naphthalene-based water reducer, which can reduce water consumption, effectively reduce water loss during the mixing of raw materials, and reduce energy consumption during construction and stirring.

[0046] In another embodiment, the high temperature calcination specifically includes: preheating and calcining at 300-400° C. for 10-14 minutes, and then calcining at 900-1100° C. for 20-25 minutes. Such a configuration can effectively improve the calcination efficiency of silica ash.

[0047] In another embodiment, the fermentation temperature of the sealed fermentation is 30-40°C, and the fermentation time is 10-12 days. Under such conditions, the fermentation is sufficient and the efficiency of producing lipophilic ester groups is high.

[0048] In a second aspect, the present invention provides a groove tile produced by using the solid waste reuse groove tile production process as described above.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made by any technician familiar with the field within the spirit and principle of the present invention should be included in the scope of protection of the present invention.
