Description

Technical Field

[0001] This invention relates to the field of arts and crafts technology, specifically to a salt carving preparation process and salt carving products. Background Technology

[0002] Salt sculpture is a craft made primarily from salt. The production of a salt sculpture involves nearly ten steps, starting with material selection. Among these, the shaping and setting process is crucial for achieving good translucency and long-term preservation.

[0003] Existing salt sculpture manufacturing processes typically involve pouring a mixture of salt and resin into a mold, first molding under high pressure, and then setting it at high temperature. The main drawbacks of this method are: 1. The process conditions are demanding, with high energy consumption due to the high pressure and high temperature conditions; 2. The high-pressure molding operation generally takes three hours, and the high-temperature setting operation generally takes six hours, which is time-consuming. Secondly, the raw material for salt sculptures is salt, and the chemical properties of salt make them prone to absorbing moisture. After absorbing moisture, the salt sculpture is prone to fluidization, resulting in a dull surface or reduced luster, significantly affecting its aesthetic appeal. Thirdly, salt sculptures are fragile and have poor stability when subjected to impacts.

[0004] To address the issues of salt sculptures being easily melted by moisture and crumbling upon contact, existing technologies involve spraying a mixture of epoxy resin and a hardener onto the outer surface of the raw salt sculpture. This protective coating isolates the sculpture from the air, preventing oxidation, dust adsorption, and the effects of humidity, while also increasing its strength. However, this existing technology does not disclose the method for manufacturing the raw salt sculpture. Furthermore, it involves spraying three layers of protective coating—a base layer, a middle layer, and a surface layer—on the raw sculpture. Each layer requires curing, grinding, and polishing, thus failing to solve the problems of high energy consumption and long production time. Additionally, the transition between the protective coating and the sculpture itself is somewhat abrupt, resulting in a less than ideal finish. Summary of the Invention

[0005] To address the high energy consumption and long time consumption issues associated with high-pressure molding and high-temperature setting processes for salt sculpture products, this invention provides a salt sculpture preparation process and salt sculpture products. The salt sculpture production process does not use high temperature and high pressure, and there is no need to spray a protective coating on the outer surface of the salt sculpture body. The prepared salt sculpture products directly have water resistance properties, and the surface effect is bright and transparent, with high ornamental value.

[0006] In a first aspect, the present invention provides a salt carving preparation process, comprising the following steps:

[0007] (1) After mixing the base material and the curing agent, apply the mixture evenly to the inner surface of the salt sculpture mold and let it stand. The mass ratio of the base material to the curing agent is 100:0.01~0.18.

[0008] (2) Mix the base material with salt, then add the curing agent and mix. Then apply the mixture evenly to the inside of the salt sculpture mold and let it stand. The mass ratio of base material to salt is 100:80~100, and the mass ratio of base material to curing agent is 100:0.05~0.25.

[0009] (3) Mix the base material with salt, then add the curing agent and mix. Fill the salt sculpture mold and let it stand. The mass ratio of base material to salt is 100:400~800, and the mass ratio of base material to curing agent is 100:0.05~0.3.

[0010] (4) Demolding: Soak the salt sculpture blank in caustic soda water, take it out and clean the surface;

[0011] (5) Polish the surface of the salt sculpture blank until smooth, and you will get the desired result;

[0012] In steps (1) to (3), the base material preparation method is as follows: the resin, accelerator and aluminum hydroxide powder with a mass ratio of 950~1560:3.5~18:460~1300 are stirred and mixed, left to stand, and then placed in a vacuum machine for treatment. The vacuum pressure is -0.075~-0.1MPa and the vacuum treatment time is 5~10 minutes.

[0013] Furthermore, in step (1), the settling time is 5 to 20 minutes.

[0014] Furthermore, in step (2), the mixing time of the base material and salt is 3 to 5 minutes, and the standing time is 5 to 20 minutes.

[0015] Furthermore, in step (3), the mixing time of the base material and salt is 10-18 minutes, and the standing time is 5-30 minutes.

[0016] Furthermore, in step (4), the concentration of caustic soda solution is 15%~30%, and the soaking time is 20~35 minutes.

[0017] Furthermore, in step (5), a high-gloss varnish is applied to the outer surface of the salt sculpture after polishing.

[0018] Furthermore, the resin in the base material is 7934 resin.

[0019] Secondly, the present invention provides a salt sculpture product made using the above-described salt sculpture preparation process.

[0020] The beneficial effects of this invention are as follows:

[0021] The salt sculpture preparation process provided by this invention is carried out at room temperature, with a short preparation time, effectively solving the problems of high energy consumption and long processing time in traditional salt sculpture processes. First, the outermost layer of the salt sculpture is made on the mold surface. This outermost layer consists of a base material and a curing agent. The accelerator in the base material promotes resin coagulation and shortens the coagulation time. Aluminum hydroxide powder gives the product a more textured feel, while also increasing the weight of the salt sculpture, reducing the plastic feel, and improving the product's tactile experience. No salt is added to the outermost layer, which isolates the salt from air in the salt sculpture, solving the problem of a dull, opaque surface caused by the water-receptive nature of salt. The middle layer consists of a base material, salt, and a curing agent. The amount of salt is controlled to be 80%~100% of the base material's weight. In the core, the amount of salt is increased to 400%~800% of the base material's weight, creating a gradual increase in salt particles from the outside in, resulting in a more lustrous appearance and better aesthetic effect. After demolding, the salt sculpture blank is soaked in caustic soda water to remove surface stickiness, which facilitates the subsequent surface polishing.

[0022] The salt sculptures provided by this invention have a bright color, good transparency, rich layers, strong ornamental value, and long ornamental life. They overcome the problem of salt sculptures turning dull when damp and can be cleaned directly with a damp cloth. Detailed Implementation
