Description

Technical Field

[0001] This invention relates to the field of artificial quartz stone preparation technology, and more specifically, to a method for preparing high-toughness inorganic artificial quartz stone. Background Technology

[0002] As a decorative building material, artificial stone, containing over 92% natural marble, retains the noble and elegant characteristics of natural stone. It also boasts vibrant colors, uniform color, precise dimensions, high gloss, pressure resistance, wear resistance, good breathability, environmental friendliness, and the ability to be repeatedly renovated, making it widely popular due to its versatility. Utilizing scraps and other auxiliary materials from natural stone processing to synthesize artificial stone has become a major trend in the stone market.

[0003] CN109776044A discloses a novel high-strength inorganic artificial quartz stone. However, this artificial quartz stone exhibits low drop ball impact strength, and is prone to chipping, corner breakage, and fracture during processing, transportation, and construction. Existing artificial quartz stone typically improves toughness by adding toughening fibers to the formula, but this often requires a relatively high fiber content; otherwise, the toughening effect is not significant. High fiber content can also lead to poor dispersion, resulting in "floating fibers" and other issues that negatively impact the decorative effect of the surface. Furthermore, existing artificial quartz stones also suffer from high water absorption.

[0004] In summary, based on the applicant's extensive research, at least the following problems exist in this field: "floating fiber" in the addition of toughening fibers to artificial quartz stone, as well as low impact strength and high water absorption of artificial quartz stone when dropped by a ball. Therefore, it is necessary to develop or improve a method for preparing high-toughness inorganic artificial quartz stone. Summary of the Invention

[0005] Based on this, in order to solve the problem of "floating fibers" when adding toughening fibers to artificial quartz stone, as well as the problems of low impact strength and high water absorption of artificial quartz stone when dropped by a ball, this invention provides a method for preparing high-toughness inorganic artificial quartz stone, the specific technical solution of which is as follows:

[0006] A method for preparing high-toughness inorganic artificial stone includes the following steps:

[0007] By weight, add 60-70 parts of aggregate, 5-10 parts of calcium carbonate powder, 2-4 parts of metakaolin, 18-22 parts of white cement, 0.9-1.5 parts of water-reducing agent, 0.5-5 parts of polymer compound, 3-8 parts of water and 0.3-1.5 parts of inorganic pigment to a mixer and mix evenly to obtain a mixture.

[0008] Then close the top door of the mixer, start the vacuum instrument, set the vacuum degree to -98 to -55 kPa, evenly disperse the mixture into the pre-made mold, then vibrate and press repeatedly three times, then compact and smooth the surface, and then cure at 25 to 29°C for 15 to 20 hours to obtain the artificial quartz stone blank.

[0009] The artificial quartz stone blank is demolded, then sprayed with water for curing for 25-30 days, and then sawn, ground, polished, processed and tested to obtain the high-toughness inorganic artificial quartz stone.

[0010] Furthermore, the vacuum condition is a vacuum degree of -98 to -55 kPa.

[0011] Furthermore, the aggregate includes at least one of granite sand, marble sand, and quartz sand.

[0012] Furthermore, the inorganic pigment includes at least one of titanium dioxide, iron oxide red, iron oxide yellow, iron oxide black, and carbon black.

[0013] Furthermore, the water-reducing agent includes at least one of phosphate water-reducing agents, sodium lignosulfonate water-reducing agents, naphthalene-based high-efficiency water-reducing agents, aliphatic high-efficiency water-reducing agents, amino high-efficiency water-reducing agents, and polycarboxylate high-efficiency water-reducing agents.

[0014] Furthermore, the vibration suppression conditions are: low-speed oscillation for 60s, low-speed vibration for 60s, high-speed oscillation for 60s, and high-speed vibration for 60s.

[0015] Furthermore, the polymeric compound includes at least one of polyacrylamide, ethylene-vinyl acetate copolymer, butadiene-styrene copolymer, styrene-acrylate copolymer, and modified polyvinyl alcohol.

[0016] Furthermore, the raw materials for preparing the modified polyvinyl alcohol include polyvinyl alcohol, water, N-propylethylenediamine, ethylene glycol, aldehyde-ketone resin, and abietic triglyceride.

[0017] Furthermore, the preparation method of the modified polyvinyl alcohol includes the following steps:

[0018] Polyvinyl alcohol is added to water and heated to 96-98°C. The mixture is then stirred at 600-700 r / min until homogeneous. N-propylethylenediamine and ethylene glycol are then added, and the stirring speed is maintained at 800-860 r / min. The mixture is then heated to 120-130°C and reacted for 2-3 hours. Finally, aldehyde-ketone resin and abietic triglyceride are added and reacted for 1.1-1.6 hours to obtain the modified polyvinyl alcohol.

[0019] Further, the mass ratio of polyvinyl alcohol, water, N-propylethylenediamine, ethylene glycol, aldehyde-ketone resin and abietic triglyceride is 90-95:110-120:5-10:33-38:5-10:1-3.

[0020] The preparation method provided by the above technical solution effectively solves the "floating fiber" problem caused by the existing method of using toughening fibers to improve the toughness of the board by employing at least one polymer compound selected from polyacrylamide, ethylene-vinyl acetate copolymer, butadiene-styrene copolymer, styrene-acrylate copolymer and modified polyvinyl alcohol. It also effectively improves the drop ball impact strength and reduces the water absorption rate. The high-toughness inorganic artificial quartz stone prepared by this method has no appearance problems and has high drop ball impact strength and low water absorption rate. Detailed Implementation
