Manufacturing method based on siraitia grosvenorii shell carving process

Abstract

The invention belongs to the technical field of arts and crafts processing, particularly relates to a preparation method of sculpture artwork based on momordica grosvenori, and aims to overcome the technical defects that in traditional momordica grosvenori sculpture, shells are prone to cracking, the corrosion resistance is poor, and the coloring effect is poor. The core process comprises the following steps: structural strengthening: drilling holes at pedicels to take kernels, and keeping the integrity of an inner cavity; the inner shell cavernous body is infiltrated by epoxy liquid and is air-dried at constant temperature for 48 hours to form a hardened layer, and the compressive strength is improved to 50-55 MPa; preservative treatment: adopting a dual sugar control path-epoxy liquid solidification isolation sugar degradation or a traditional boiling method to dissolve cavernous body sugar, so that the sugar residual rate is less than or equal to 2%, and the mildew-proof period is more than or equal to 50 years; sculpture and coloring: after sculpture of the line drawing, mineral pigment (such as cinnabar) is used for three times of color filling, air drying needs to be thorough in each process, and it is ensured that the color fastness reaches GB / T 3920-2008 grade 4 or above; waterproof and light paint is sprayed on the surface to isolate air, and the product is placed in a device composed of a glass cover and a wood chip base to adsorb moisture, prevent mildew and maintain color stability. The method has the technical effects that the mechanical strength, long-acting corrosion resistance and aesthetic performance of the siraitia grosvenorii carved product are remarkably improved, and the siraitia grosvenorii carved product is suitable for fine art creation and long-term storage.

Description

Technical Field

[0001] The present invention belongs to the technical field of arts and crafts processing, and particularly relates to a method for preparing a carved art work based on Momordica grosvenori, especially including innovative processes such as fruit shell structure strengthening, anti-corrosion treatment, and mineral coloring. Background Art

[0002] Defects of the Existing Technology The following problems exist in traditional Momordica grosvenori carving: The fruit shell is prone to cracking: The existing thin fruit shell carving belongs to a brittle and easily cracked thin and tough material. The outer shell of Momordica grosvenori is thin and brittle, and the inside is hollow with many pulp cavities. Traditional carving methods are likely to cause it to break and open, making it difficult to achieve fine and stable artistic creation. Poor anti-corrosion ability: The untreated fruit shell is prone to mildew in a humid environment. Technical blank: Existing patented technologies only focus on the extraction of medicinal components and do not solve the problems of the mechanical strength and aesthetic performance of carved art works. Poor coloring effect: Ordinary pigments have poor adhesion and are prone to fading. Summary of the Invention

[0003] Provide a Momordica grosvenori carving process to solve the carving problems caused by the thin and brittle outer shell of Momordica grosvenori and its complex internal structure, and achieve fruit shell structure strengthening (compressive strength ≥ 50 MPa), long-term anti-corrosion (mildew prevention ≥ 50 years), and stable attachment of mineral colors. Technical Solution

[0004] Fruit shell pretreatment technology: Drill and remove the core: Open a hole with a diameter of 20 mm at the fruit stalk, drill at the umbilicus of the Momordica grosvenori vine stem to remove the seed core and pick it out and clean it flat, retaining the integrity of the inner cavity. Epoxy liquid impregnation: Place the epoxy liquid into the inner cavity of the fruit shell and slowly rotate the fruit shell to let the liquid soak into the first layer of sponge body of the inner fruit shell. Place the fruit shell immersed in the liquid in a constant temperature air-drying oven and let it stand for 48 hours until it is completely dry and hardened to be able to withstand the pressure during carving.

[0005] Sugar control and anti-corrosion: Treat the sugar in two paths - 1. That is, use the epoxy liquid to soak into the first layer of sponge body structure of the inner fruit shell, and the sugar in the sponge body hardens and isolates the air and the epoxy co-substance is not easily degraded, playing a role in waterproofing, moisture-proofing and mildew-proofing for more than 20 years. 2. Use the traditional folk ancient method, put the empty fruit shell into a pot and boil it with cold water, so that the sugar in the sponge body dissolves into the boiling water. Ensure that the second layer of tough texture of the inner fruit shell is intact without breaking or cracking. The tough texture part itself has no nutrients such as vitamins and is the main part for embossing.

[0006] Carving and coloring process: Line drawing carving: Use line drawing to outline the carving content, and carve with even force along the line drawing. During the unfinished process, it needs to be placed in a drying box to prevent moisture absorption. Refine and tidy the literal picture, and clean the concave surface. After the process is completed, place it in the drying box to dry until the next process; Mineral pigments: Fill and paint the Thangka with mineral pigments and cinnabar, and brighten and blend with gelatin. Before coloring, vacuum clean under the condition of the dried fruit shell to ensure no impurities and dust, which is necessary to ensure bright color. For the first coloring to level the base, three rounds of coloring are required to dry thoroughly and fill the surface of the fruit shell flat to complete the color painting. Ensure that each coloring is dried thoroughly in the drying box without moisture adhering to the surface.

[0007] Sealing and protection technology: Surface spraying: Evenly spray the outer surface of the fruit shell with oil painting waterproof and shiny paint to make the fruit shell in a vacuum coating state isolated from the air from the inside to the outside. The key to this process is to prevent moisture and mildew; Storage device: Use a glass dust-proof cover for the work decoration plus an accessory sawdust base to keep the inside of the cover dry and breathable. The sawdust base can adsorb the moisture in the air and prevent bacteria, so that the Siraitia grosvenorii carving work in the cover always maintains bright and beautiful color.

[0008] Technical effects Mechanical properties: The compressive strength of the hardened layer is increased to 50 - 55 MPa; Anticorrosion ability: The sugar residue rate ≤ 2%, and the mildew-proof period ≥ 50 years; Aesthetic performance: The color fastness of the mineral pigment reaches above Grade 4 of GB / T 3920 - 2008.
