TECHNICAL FIELD

[0001] The application belongs to the technical field of composite materials, and relates to a preparation process of a volcanic rock composite material and a moisture-absorbing and sweat-releasing fabric. BACKGROUND

[0002] The volcanic rock is a functional and environment-friendly material, is a porous stone formed by volcanic glass, minerals and bubbles after volcanic eruption, contains dozens of minerals and trace elements such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and molybdenum, has the functions of reflecting ultraviolet light, and the like, and has a porous surface structure after being added and prepared into yarn and fabric, is good in water absorption, is strong in moisture absorption and sweat release, has a certain ultraviolet light reflection function, and can deepen color and reduce dye addition.

[0003] In the prior art, the volcanic rock is generally directly or after surface modification prepared into a master batch, and then added into a polymer material to prepare yarn or fiber. This causes a problem that the master batch material or the polymer material is easy to enter the porous structure of the volcanic rock, and the porous structure of the volcanic rock is partially or totally blocked, so that the porous characteristics and effects of the volcanic rock cannot be exerted, and the moisture absorption and sweat release function of the fabric is affected.

[0004] Therefore, it is urgent to solve the above problems. SUMMARY

[0005] In order to solve the above technical problems, the application provides a preparation process of a volcanic rock composite material and a moisture-absorbing and sweat-releasing fabric.

[0006] The technical scheme of the application is as follows:

[0007] A preparation process of a volcanic rock composite material, comprising the following steps:

[0008] Mixing volcanic rock and powder particles to obtain a premix;

[0009] Dispersing the premix into a polymer base material, and shaping to obtain a preform;

[0010] Cleaning the preform with an acidic liquid to obtain the volcanic rock composite material;

[0011] The powder particles can react with the acidic aqueous solution at 100 DEG C or below, and the reaction product can be dissolved in the acidic aqueous solution.

[0012] Preferably, the average particle size of the volcanic rock is 1-30 microns.

[0022] The beneficial effects of the present application are:

[0023] (1) The present application uses powder particles to treat and block the porous structure of the volcanic rock in advance. The treated volcanic rock cannot be penetrated by the polymer matrix in the forming process. The composite material of the volcanic rock and the polymer matrix is formed, and then the porous structure of the volcanic rock is restored by the reaction of the acidic liquid and the powder particles.

[0027] The technical solutions of the present application are further described and explained in the following specific embodiments.

[0028] In order to solve the problem that the porous structure of the volcanic rock is blocked by the polymer matrix after the volcanic rock and the polymer matrix form a composite material, on the one hand, the present application provides a preparation process of a volcanic rock composite material, comprising the following steps:

[0029] Mixing the volcanic rock and the powder particles to obtain a premix;

[0030] Dispersing the premix into a polymer matrix, shaping to obtain a preform;

[0031] Cleaning the preform with an acidic liquid to obtain a volcanic rock composite material;

[0032] The powder particles can react with the acidic aqueous solution at 100°C or below, and the reaction product can be dissolved in the acidic aqueous solution.

[0033] For example, taking the preparation of the preform by melt extrusion as an example, the operation method can be as follows: (1) drying each raw material component; (2) weighing each dried raw material component according to the formula; (3) mixing the premix and the polymer matrix (or other raw material components such as antioxidants, dispersants, etc.) into a mixer, stirring at a stirring rate of 100-150 r / min for 15-30 min for mixing; (4) adding the above mixture into a twin-screw extruder for melt extrusion granulation or direct shaping, and then drying. The twin-screw extruder can be set at 11 zones, for example, for PET resin, the temperature settings are 150-160°C, 230-240°C, 240-250°C, 250-260°C, 250-260°C, 220-230°C, 220-230°C, 220-230°C, 220-230°C, 220-230°C, 240-250°C, respectively. The cooling temperature is 15-30°C. The screw rotation speed of the twin-screw extruder is set to 300-500 r / min. If melt extrusion granulation is used, the obtained masterbatch can be added to conventional chemical fiber polymers for melt spinning and shaping.

[0034] The present application uses powder particles to pre-block the porous structure of volcanic rock, and then mixes and shapes it with a polymer matrix, such as fiber, particle, board, etc. The polymer matrix cannot enter the porous structure of the volcanic rock. Then the acidic solution reacts with the powder particles on the surface of the shaped material (fiber, particle, board, film, etc.), and the reaction product is dissolved in the acidic solution. As the acidic solution gradually penetrates, the blocking powder particles of the volcanic rock from the outside to the inside of the shaped material are gradually reacted and dissolved. The acidic solution can penetrate into the porous structure of the volcanic rock inside the shaped material and react with the powder particles, and the product is dissolved in the acidic solution. The porous structure of the volcanic rock is restored, so that the volcanic rock of the obtained volcanic rock composite material has its original porous structure, and the volcanic rock composite material has good moisture absorption and ventilation function.

[0035] Specifically, the method for preparing the premix by mixing the volcanic rock and the powder particles is not particularly limited, and one method can be as follows: mixing the volcanic rock and the powder particles, vibrating by using a vibrating screen (for example, the mesh can be 300-500 mesh), and obtaining the premix, which can promote the blocking of the powder particles to the porous structure of the volcanic rock and remove the excess powder particles, so as to avoid the absorption of the excess powder particles on the surface of the volcanic rock, and then when the powder particles are mixed with the polymer matrix, the powder particles are left in the polymer matrix. Alternatively, further, after the above-processed volcanic rock is soaked in water for a certain period of time (for example, 1-30 min) to remove the powder particles on the surface of the volcanic rock, the filled powder particles in the porous structure of the volcanic rock still exist, and then the volcanic rock is separated and dried, and the premix is obtained.

[0036] In one preferred embodiment of the present application, the average particle size of the volcanic rock is 1-30 μm. If the average particle size of the volcanic rock is too low, it is easy to agglomerate, and the moisture absorption and air permeability performance is not good; if the average particle size of the volcanic rock is too large, it will affect the mechanical properties of the volcanic rock composite material. Those skilled in the art know that for different forming materials, the average particle size of the volcanic rock can be different, for example, for fibers, the average particle size of the volcanic rock can be 1-10 μm, or further, 1-5 μm; for plates, the average particle size of the volcanic rock can be 10-30 μm. Specifically, the average particle size of the volcanic rock can be any one of 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, 15 μm, 16 μm, 17 μm, 18 μm, 19 μm, 20 μm, 21 μm, 22 μm, 23 μm, 24 μm, 25 μm, 26 μm, 27 μm, 28 μm, 29 μm, 30 μm, etc., but is not limited to the above-listed values.

[0037] In one preferred embodiment of the present application, the powder particles are selected from one or a combination of two or more of carbonates, bicarbonates, metal hydroxides, and metal oxides. The above-mentioned powder particles can react with an acidic solution at 100°C and below, and the reaction product is dissolved in the acidic solution, so that the blocked porous structure of the volcanic rock recovers the porous properties. For example, the carbonates can be sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate, lithium carbonate, zinc carbonate, ammonium carbonate, etc., the bicarbonates can be sodium bicarbonate, potassium bicarbonate, magnesium bicarbonate, ammonium bicarbonate, etc., the metal hydroxides can be sodium hydroxide, potassium hydroxide, lithium hydroxide, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, barium hydroxide, zinc hydroxide, etc., and the metal oxides can be calcium oxide, magnesium oxide, zinc oxide, lithium oxide, barium oxide, etc. In the present application, the powder particles can be nanoscale, such as 10 nm-500 nm, so as to facilitate the powder particles to enter the porous structure of the volcanic rock.

[0038] In one preferred embodiment of the present application, the weight ratio of the volcanic rock and the powder particles is in the range of 20:1 to 1:10. The weight ratio of the volcanic rock and the powder particles in the above range, the powder particles are in excess or just right relative to the volcanic rock, which can better block the porous structure of the volcanic rock. For example, the weight ratio of the volcanic rock and the powder particles can be any value in the range of 20:1, 18:1, 16:1, 15:1, 12:1, 10:1, 8:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, etc., but not limited to the above listed.

[0039] In one preferred embodiment of the present application, the weight ratio of the premix and the polymer substrate is in the range of 3-40:100. The weight ratio of the premix and the polymer substrate in the above range, which can better play the hygroscopic and breathable effect of the volcanic rock. For example, the weight ratio of the premix and the polymer substrate can be any value in the range of 3:100, 4:100, 5:100, 6:100, 7:100, 8:100, 9:100, 10:100, 11:100, 12:100, 13:100, 14:100, 15:100, 16:100, 17:100, 18:100, 19:100, 20:100, 21:100, 22:100, 23:100, 24:100, 25:100, 26:100, 27:100, 28:100, 29:100, 30:100, 31:100, 32:100, 33:100, 34:100, 35:100, 36:100, 37:100, 38:100, 39:100, 40:100, etc., but not limited to the above listed.

[0040] In one preferred embodiment of the present application, the dispersion method is selected from one of bulk blending and solution blending. Bulk blending refers to blending the volcanic rock (or the volcanic rock pre-prepared into a volcanic rock masterbatch) with a polymer bulk. Based on the properties of the polymer bulk, bulk blending can be divided into melt blending and room temperature blending. For polymer materials that are solid at room temperature, such as polyethylene, polypropylene, polyurethane, etc., melt blending can be used. In melt blending, the volcanic rock is directly mixed with the polymer base material, and then heated to melt the polymer base material. The volcanic rock and the liquid polymer base material are mixed by shearing action of external force, or the volcanic rock can be pre-prepared into a masterbatch with part of the polymer base material, and then mixed with the remaining polymer base material. After melt blending, the molding can be extrusion molding, injection molding, compression molding, etc., and the molded profile can be in the form of fiber, film, sheet, particle, etc. For polymer materials that are in a rubber state at room temperature, such as polysiloxane, nitrile rubber, ethylene-propylene-diene rubber, etc., room temperature blending can be used. The volcanic rock is dispersed into the polymer material by external force such as screw shearing, or the volcanic rock can be further cured with a curing agent at a certain temperature. After room temperature blending, the molding can be extrusion molding, injection molding, compression molding, etc., or a curing agent or crosslinking agent can be added for further crosslinking and curing. Solution blending can be mixing the polymer base material with a solvent (water or an organic solvent) to form a polymer solution, then adding the volcanic rock and mixing by shearing action of external force, and then molding by solution spinning, film casting, etc. The molded profile can be in the form of fiber, film, etc.

[0041] The preparation process of the volcanic rock composite material of the present application has no particular limitation on the polymer base material. In one preferred embodiment of the present application, the polymer base material is selected from one or a combination of two or more of natural polymers and synthetic polymers. For example, the natural polymer can be cotton fiber, hemp fiber, wool fiber, silk fiber; the synthetic polymer can be polyethylene, polypropylene, polyurethane, polyester, acrylate resin, epoxy resin, polyurea, nylon, polyvinyl chloride, polyacrylonitrile, polystyrene, etc.

[0042] In one preferred embodiment of the present application, the pH of the acidic liquid is no more than 4. The acidic solution of the present application can be an organic acid or an inorganic acid, and can be a pure acid or an acidic aqueous solution. For an organic acid, such as acetic acid, malic acid, citric acid, oxalic acid, tartaric acid, methanesulfonic acid, trifluoromethanesulfonic acid, benzoic acid, benzene sulfonic acid, methylbenzene sulfonic acid, etc., it can be a pure acid or an acidic aqueous solution, and the concentration of the acidic aqueous solution can be 0.01-10 mol / L, such as any one of 0.01 mol / L, 0.1 mol / L, 0.3 mol / L, 0.5 mol / L, 1 mol / L, 2 mol / L, 3 mol / L, 4 mol / L, 5 mol / L, etc., but is not limited to the above-listed values. For an inorganic acid, it can be an inorganic acid aqueous solution, such as a hydrochloric acid solution, a sulfuric acid solution, a nitric acid solution, a phosphoric acid solution, etc., and the concentration can be 0.01-3 mol / L, such as any one of 0.01 mol / L, 0.1 mol / L, 0.3 mol / L, 0.5 mol / L, 1 mol / L, 1.5 mol / L, 2 mol / L, 2.5 mol / L, 3 mol / L, etc., but is not limited to the above-listed values. The pH of the acidic liquid is no more than 4, which can react with the powder particles more quickly. Further, the pH of the acidic liquid is no more than 3, for example, the pH can be any one of 3, 2.8, 2.5, 2.3, 2.2, 2, 1.8, 1.6, 1.5, 1.2, 1, 0.8, 0.5, 0.3, 0.2, 0, etc., but is not limited to the above-listed values.

[0043] In another aspect, the present application provides a moisture-absorbing and sweat-releasing fabric prepared by the preparation process of the volcanic rock composite material according to any one of the above embodiments. The above polymer substrate is selected as a material commonly used for fabrics, such as synthetic, polypropylene, aramid, spandex, polyester, nylon, acrylic, etc., and natural, cotton, hemp, etc., and the fabric with the moisture-absorbing and sweat-releasing function can be prepared. In addition to the volcanic rock and the polymer substrate, the fabric can also contain antioxidants, antistatic agents, ultraviolet-resistant agents, dispersants, dyes, etc., which can be further selected and used according to the specific function of the fabric.

[0044] In one preferred embodiment of the present application, the preform is first prepared into an initial fabric, and then washed with an acidic aqueous solution to obtain the fabric.

[0045] Alternatively, the volcanic rock composite material is prepared into a fabric.

[0046] Using the above two preparation methods, the volcanic rock composite material prepared by the present application can be further prepared into a fabric with the moisture-absorbing and sweat-releasing function.

[0047] The technical solutions of the present application are further described and explained according to the embodiments below. Unless otherwise specified, the parts in the following embodiments are weight parts.

[0048] Example 1

[0049] 20 parts of volcanic rock with an average particle size of 3 μm and 1 part of sodium carbonate with an average particle size of 80 nm were mixed in a three-dimensional mixer for 10 min, transferred to a 500-mesh vibrating screen for screening, and a premix was obtained.

[0050] PET polyester raw materials were pre-dried. 10 parts of the above premix and 100 parts of PET polyester were mixed and added to a twin-screw extruder to be extruded into fibers (0.5 mm in diameter) to obtain preformed fibers.

[0051] The above preformed fibers were soaked in an acetic acid solution (10 wt% concentration) and ultrasonically cleaned for 5 min, removed, ultrasonically cleaned with water for 2 times, and dried at 60°C overnight to obtain volcanic rock composite fibers.

[0052] In the present application, the SEM picture of the volcanic rock composite fiber is shown in Figure 1. Figure 1 As can be seen, the surface of the volcanic rock composite fiber has a rich porous structure; the SEM picture of the above preformed fiber is shown in Figure 2. Figure 2 As can be seen, the surface of the fiber is covered with polypropylene, and the porous structure of the volcanic rock is basically not visible.

[0053] Therefore, the preparation process of the present application can avoid the porous structure of the volcanic rock being blocked by the polymer matrix, maintain the porous structure of the volcanic rock, so that the volcanic rock composite fiber can play the characteristics of the volcanic rock, and the absorption and air permeation effect is good.

[0055] The difference between Example 2 and Example 1 is that in Example 1, 20 parts of volcanic rock with an average particle size of 3 μm is adjusted to 14 parts, and 1 part of sodium carbonate with an average particle size of 80 nm is adjusted to 7 parts. The remaining steps remain unchanged.

[0056] Example 3

[0057] The difference between Example 3 and Example 1 is that in Example 1, 20 parts of volcanic rock with an average particle size of 3 μm is adjusted to 10 parts, and 1 part of sodium carbonate with an average particle size of 80 nm is adjusted to 11 parts. The remaining steps remain unchanged.

[0058] Example 4

[0059] The difference between Example 4 and Example 1 is that in Example 1, 20 parts of volcanic rock with an average particle size of 3 μm is adjusted to 2 parts, and 1 part of sodium carbonate with an average particle size of 80 nm is adjusted to 19 parts. The remaining steps remain unchanged.

[0064] Comparative Example 3

[0065] The difference between Comparative Example 3 and Comparative Example 2 is that the weight of untreated volcanic rock in Comparative Example 2 is adjusted from 10 parts to 0 parts. The remaining steps remain unchanged.

[0066] Comparative Example 4

[0067] The difference between Comparative Example 4 and Comparative Example 2 is that the weight of untreated volcanic rock in Comparative Example 2 is adjusted from 10 parts to 20 parts. The remaining steps remain unchanged.

[0068] Example 5

[0069] 10 parts of volcanic rock with an average particle size of 5 μm and 10 parts of sodium bicarbonate with an average particle size of 200 nm were mixed in a three-dimensional mixer for 10 min and transferred to a 500-mesh vibrating screen for screening. The treated volcanic rock screened out was added to 100 parts of water, stirred for 3 min, filtered, and the solid was dried at 100°C for 6 hours to obtain a premix.

[0070] 3 parts of the above premix and 100 parts of PET polyester were mixed and added to a twin-screw extruder to be extruded into fibers (1 mm in diameter) to obtain a preformed fiber;

[0071] The above preformed fiber was soaked in a sulfuric acid solution with a concentration of 0.1 mol / L for 2 min, taken out, ultrasonically washed with clean water 3 times, and dried at 60°C overnight to obtain a volcanic rock composite fiber.

[0072] Example 6

[0073] The difference between Example 6 and Example 5 is that in Example 5, the premix is adjusted from 3 parts to 10 parts. The remaining steps remain unchanged.

[0076] Example 8

[0077] The difference between Example 8 and Example 5 is that in Example 5, the premix is adjusted from 3 parts to 40 parts. The remaining steps remain unchanged.

[0078] The dry speed, wick height, water absorption rate and drop water diffusion time were tested according to the method of GB / T 21655.1-2023. The results are shown in Table 1 below. The faster the dry speed, the greater the wick height, the higher the water absorption rate, the shorter the drop water diffusion time, indicating the better moisture absorption and air permeability.

[0079] Table 1

[0080]

[0081] Comparing the data results in Table 1 above, it can be seen from Examples 1-4 that changing the ratio of volcanic rock and powder particles has no obvious effect on the water absorption and air permeability of the volcanic rock composite fiber. The reason is that as long as the porous structure of the volcanic rock is fully blocked, and then the powder particles are fully removed with an acidic solution, the porous structure is restored and the effect is exerted. Comparing Examples 1-4, Comparative Example 2, Comparative Example 4 and Comparative Example 3, adding untreated volcanic rock can improve the water absorption and air permeability, but the effect is not very obvious. If the porous structure is blocked and not cleaned and removed, the water absorption and air permeability cannot be exerted. Comparing Examples 5-8, the air permeability and moisture absorption become better and better with the increase of the amount of volcanic rock.

[0082] Example 9

[0083] 10 parts of volcanic rock with an average particle size of 10 μm and 10 parts of sodium bicarbonate with an average particle size of 500 nm were mixed in a three-dimensional mixer for 10 min, transferred to a 500-mesh vibrating screen for screening, and the treated volcanic rock screened out was added to 100 parts of water, stirred for 3 min, filtered, and the solid was dried at 100°C for 6 hours to obtain a premix.

[0084] 15 parts of the above premix, 100 parts of polyurethane elastomer TPU, 0.5 parts of antioxidant 1010, 0.6 parts of UV-327 and 1 part of KH-560 coupling agent were mixed, added to a mixing machine for mixing, and then a preformed plate with a size of 10 cm x 10 cm x 2 mm was prepared by a molding method.

[0085] The above preformed plate was soaked in an oxalic acid solution with a concentration of 0.1 mol / L and ultrasonically cleaned for 10 min, taken out, ultrasonically cleaned with water for 3 times, and dried at 60°C overnight to obtain a volcanic rock composite plate.

[0086] Example 10

[0087] The difference between Example 10 and Example 9 is that in Example 9, the average particle size of the volcanic rock is adjusted from 10 μm to 30 μm. The remaining steps remain unchanged.

[0088] Comparative Example 5

[0089] The difference between Comparative Example 5 and Example 9 is that in Example 9, the premix is replaced by an equal weight of untreated volcanic rock (in Example 9). The remaining steps remain unchanged.

[0090] Comparative Example 6

[0091] 100 parts of the polyurethane elastomer TPU in Example 9, 0.5 parts of antioxidant 1010, 0.6 parts of UV-327 and 1 part of KH-560 coupling agent are mixed and added to a mixer for mixing, and then a polyurethane plate with a size of 10 cm x 10 cm x 2 mm is prepared by a mold pressing method.

[0092] The drop water diffusion time is tested according to the method of GB / T 21655.1-2023, and the drop water diffusion times of the plates of Example 9, Example 10, Comparative Example 5 and Comparative Example 6 are 2.1 s, 1.8 s, 4.9 s and 5.5 s respectively, and the drying speeds are 0.38 g / h, 0.41 g / h, 0.20 g / h and 0.17 g / h respectively. Therefore, the process method of the present application can significantly improve the moisture absorption and air permeability of the volcanic rock composite material.
