In the present invention, when involving numerical ranges, unless otherwise specified, the two endpoints of the numerical range are included.

[0052] In order to solve the above problems, the present invention provides a translucent soft stone, which includes the following components by weight: 30-60 parts of quartz sand, 40-60 parts of limestone, 1-5 parts of additives, and 10-30 parts of modified rosin resin.

[0053] Specifically, quartz sand is quartz particles obtained by crushing quartz stone. The main mineral component of quartz sand is silicon dioxide, which has high hardness and wear resistance and stable chemical properties. Adding a specific proportion of quartz sand to translucent soft stone can not only improve the physical strength of the translucent soft stone, but also improve the wear resistance of the translucent soft stone. In some embodiments, the exemplary weight parts of the quartz sand are 32 parts, 34 parts, 36 parts, 38 parts, 40 parts, 42 parts, 44 parts, 46 parts, 48 ​​parts, 50 parts, 52 parts, 54 parts, 56 parts, 58 parts, and 60 parts, not limited to the above.

[0054] In some embodiments, the fineness of the quartz sand is 70-120 mesh; using quartz sand of the above fineness can obtain better light transmittance and surface smoothness.

[0055] Limestone is a naturally formed sedimentary rock, the main component of which is calcium carbonate. It is a widely used building material. Limestone has moderate hardness, is easy to cut and process, has good weather resistance in outdoor environments, and is cheap. Adding a specific proportion of limestone to the translucent soft stone can provide strength. In some embodiments, the exemplary weight parts of the limestone are 40 parts, 42 parts, 44 parts, 46 parts, 48 ​​parts, 50 parts, 52 parts, 54 parts, 56 parts, 58 parts, and 60 parts, not limited to the above enumeration.

[0056] In some embodiments, the fineness of the limestone is 200-235 meshes; using limestone with the above fineness can obtain better light transmittance and surface smoothness.

[0057] In some embodiments, the additives include thickeners, hydrophobic agents, and defoamers. The thickeners include carboxymethyl cellulose and sodium carboxymethyl cellulose; the hydrophobic agents include silicone hydrophobic agents and fluorocarbon hydrophobic agents; the defoamers include silicone oil defoamers and polyether defoamers. Adding the above additives to the translucent soft stone can stabilize the slurry and prevent the powder from sinking. In some embodiments, the exemplary weight parts of the additives are 1 part, 2 parts, 3 parts, 4 parts, and 5 parts, not limited to the above.

[0058] Most importantly, the present invention adds a self-made modified rosin resin to the light-transmitting soft stone. In some embodiments, the modified rosin resin is prepared by the following method:

[0059] Heating and softening the rosin resin, then adding the NaOH solution, and stirring for a preset time to obtain a first mixture;

[0060] After the first mixture is heated to a preset temperature, styrene, acrylic acid, butyl methacrylate and benzoyl peroxide are added thereto to carry out a modification reaction;

[0061] After the modification reaction is completed, the pH is adjusted to 7-8 to obtain modified rosin resin.

[0062] It should be noted that NaOH is added to dissolve the rosin resin in water, styrene, acrylic acid and butyl methacrylate are added to modify the rosin resin, and benzoyl peroxide is a polymerization initiator.

[0063] In some embodiments, the step of heating and softening the rosin resin, then adding the NaOH solution, and stirring for a preset time to obtain a first mixture comprises the following steps:

[0064] The rosin resin is heated to 90°C to 100°C,

[0065] When the rosin resin is completely softened, 4 wt% to 6 wt% NaOH solution is added and stirred for 2 h to 3 h to obtain a first mixture;

[0066] The amount of the NaOH solution added is 12 wt% to 14 wt% of the amount of the rosin resin added.

[0067] It should be noted that the NaOH solution is added to soften the rosin resin. If too little NaOH solution is added, the rosin resin cannot be completely dissolved. If too much NaOH solution is added, the alkalinity is too strong, which affects the subsequent reactions.

[0068] In some embodiments, after the first mixture is heated to a preset temperature, styrene, acrylic acid, butyl methacrylate and benzoyl peroxide are added thereto to carry out a modification reaction, comprising the following steps:

[0069] After the first mixture is heated to 130° C. to 135° C., a first amount of styrene, a second amount of acrylic acid, a third amount of butyl methacrylate and a fourth amount of benzoyl peroxide are gradually added dropwise within 4 to 5 hours, and then a fifth amount of benzoyl peroxide is added within 1 to 2 hours.

[0070] Benzoyl peroxide is used as a polymerization initiator. Adding it in batches can ensure a more complete monomer reaction and reduce residual monomers, thereby improving the yield and quality of the product.

[0071] In some embodiments, the first addition amount is 22 wt% to 33 wt% of the addition amount of the rosin resin;

[0072] The second added amount is 13wt% to 25wt% of the added amount of the rosin resin;

[0073] The third added amount is 33wt% to 60wt% of the added amount of the rosin resin;

[0074] The fourth addition amount is 1wt% to 3wt% of the addition amount of the rosin resin;

[0075] The fifth added amount is 1 wt % to 3 wt % of the added amount of the rosin resin.

[0076] Adding the modifier and the initiator in the above amounts can obtain a modified resin with a suitable glass transition temperature.

[0077] Accordingly, the present invention provides a method for preparing light-transmitting soft stone, comprising the following steps:

[0078] preparing modified rosin resin;

[0079] In parts by weight, 30 to 60 parts of quartz sand, 40 to 60 parts of limestone, 1 to 5 parts of additives and 10 to 30 parts of modified rosin resin are mixed and cured to obtain translucent soft stone.

[0080] Furthermore, the present invention also provides a method for preparing light-transmitting soft stone, comprising the following steps:

[0081] preparing modified rosin resin;

[0082] By weight, 30 to 60 parts of quartz sand, 40 to 60 parts of limestone, 1 to 5 parts of additives, and 10 to 30 parts of modified rosin resin are mixed to obtain a mixed raw material;

[0083] Placing the mixed raw material into a mold to form a first blank;

[0084] performing a first drying process on the first green body to obtain a second green body;

[0085] placing a reinforcing mesh on the second green body, and then performing a second drying process to obtain a third green body;

[0086] placing a reinforcing mesh on the third green body, and then performing a third drying process to obtain a fourth green body;

[0087] After the fourth green body is demoulded, a light-transmitting soft stone is obtained.

[0088] In order to increase the strength of the light-transmitting soft stone, a reinforcement mesh is added in some embodiments. In some embodiments, the reinforcement mesh is made of a glass fiber mesh.

[0089] In some embodiments, the temperature of the first drying process is 170°C to 190°C; the temperature of the first drying process is 190°C to 210°C; the temperature of the first drying process is 220°C to 240°C.

[0090] It should be noted that in order for the reinforcement net to not affect the pattern of the light-transmitting soft stone, the reinforcement net needs to be added after the surface of the light-transmitting soft stone body solidifies. Therefore, a first drying treatment with a lower temperature is introduced. The low-temperature curing takes a longer time, making the surface of the light-transmitting soft stone body more balanced. Then the reinforcement net is placed to improve the strength of the light-transmitting soft stone and a second drying treatment is performed. The temperature of the second drying treatment is higher, which can shorten the curing time and improve the strength of the light-transmitting soft stone. Subsequently, another layer of reinforcement net is added and a third drying treatment is performed, which again enhances the strength of the light-transmitting soft stone and further shortens the curing time.

[0091] In some embodiments, the preparation of the modified rosin resin comprises the following steps:

[0092] Heating and softening the rosin resin, then adding the NaOH solution, and stirring for a preset time to obtain a first mixture;

[0093] After the first mixture is heated to a preset temperature, styrene, acrylic acid, butyl methacrylate and benzoyl peroxide are added thereto to carry out a modification reaction;

[0094] After the modification reaction is completed, the pH is adjusted to 7-8 to obtain modified rosin resin.
