Description

Technical Field

[0001] The invention belongs to the technical field of cinnabar handicrafts, and in particular relates to a raw lacquer cinnabar handicraft and a manufacturing method thereof. Background Art

[0002] Cinnabar handicrafts are made from natural mercury sulfide ore. There are many types of cinnabar handicrafts, including pendants, ornaments, seals, bracelets, necklaces, etc. These handicrafts not only have ornamental value, but also carry rich cultural connotations and symbolic meanings.

[0003] However, cinnabar handicrafts not only use cinnabar but also glue, such as 502 super glue, epoxy resin AB glue, etc. These glues will release more VOCs (volatile organic compounds), formaldehyde, benzene and its compounds which are harmful substances. Most of the cinnabar crafts are placed indoors or worn on the body, which are easy to come into contact with the human body and cause harm to the human body. Summary of the invention

[0012] As a further optimization scheme of the present invention, the raw materials for preparing the anti-bending agent include: 2-4 parts of apocynum fiber and 3-4 parts of white coconut shell fiber.

[0013] As a further optimization scheme of the present invention, the preparation process of the white coconut shell fiber filaments is as follows: (i) scraping off the inner pulp of the coconut shell and then rinsing it; (ii) placing the coconut shell in salt water for soaking and fermentation, controlling the temperature to 30-36°C and the time to 30 days; (iii) beating the coconut shell and drying it; (iv) extracting and rinsing the coconut shell fiber; (v) bleaching the coconut shell fiber with a bleaching agent to obtain white coconut shell fiber filaments.

[0014] As a further optimization scheme of the present invention, the preparation process of the anti-bending agent is as follows: (i) cutting the apocynum fiber filaments and the white coconut shell fiber filaments by a shredder to obtain apocynum fiber filaments with a length of 0.01-0.03 mm and white coconut shell fiber filaments with a length of 0.01-0.03 mm; (ii) mixing and stirring the apocynum fiber filaments and the white coconut shell fiber filaments, controlling the stirring time to 3-5 min, and controlling the stirring speed to 4-6 rps, to obtain the anti-bending agent.

[0015] As a further optimization scheme of the present invention, the raw materials for preparing the brightener include, by weight: 0.5-0.7 parts of emulsified oil, 1-2 parts of palm wax and 1-2 parts of coconut wax.

[0016] As a further optimization scheme of the present invention, the raw materials for preparing the gloss agent include: (i) mixing and stirring prune oil, an emulsifier and pure water, controlling the stirring temperature to 70-80°C, controlling the time to 30-40min, and controlling the time rotation speed to 10-14rps to obtain emulsified oil; (ii) mixing and stirring the emulsified oil, palm wax and coconut wax, controlling the stirring temperature to 50-60°C, controlling the time to 10-12min, and controlling the time rotation speed to 6-8rps to obtain a gloss agent;

[0017] The mass ratio of the prickle fruit oil, the emulsifier and the pure water is 1:0.2:0.7.

[0018] The present invention also provides a method for making a raw lacquer cinnabar handicraft, comprising the following steps:

[0019] The following steps are involved:

[0020] S1, uniformly mixing cinnabar powder, adhesive and anti-bending agent to obtain a mixture;

[0021] S2, pouring the mixture into a mold and heating to cure;

[0022] S3, taking out the molded product after molding, grinding and polishing to obtain a polished product;

[0023] S4, evenly apply the gloss agent on the polished part, dry it naturally, and obtain the raw lacquer cinnabar handicraft.

[0024] The beneficial effects of the present invention are as follows: the mixed polyol prepared by using a proper ratio of pine ester-based polyol and wood fiber-based polyol, and the adhesive prepared by using a proper ratio of the mixed polyol and urushiol avoid the use of glue, reduce the release of harmful substances such as VOCs (volatile organic compounds), formaldehyde, benzene and their compounds, and help ensure the safety of cinnabar handicrafts during indoor placement or wearing;

[0025] The anti-bending agent made of apocynum fiber and white coconut shell fiber in appropriate proportion improves the anti-bending ability of cinnabar handicrafts, thereby improving the durability of cinnabar handicrafts;

[0026] The addition of a gloss agent made of emulsified oil made from prickly ash oil, emulsifier and pure water in appropriate proportions improves the glossiness of cinnabar handicrafts and enhances the visual effect. The surface of cinnabar handicrafts with high glossiness is smoother and more delicate, and is not easy to absorb dust and stains, making them relatively easy to maintain. DETAILED DESCRIPTION
