Abstract

The invention discloses a natural degradation green ecological cinerary casket and a preparation method thereof, and belongs to the technical field of civil funeral and interment articles. The cinerary casket comprises 20-50 parts of plant fiber pulp, 8-12 parts of plant starch, 2-3 parts of sorbitol and 1-2 parts of microcrystalline cellulose. The preparation method comprises the following steps: (1) hydrolyzing and pulping to obtain plant fiber pulp; (2) extracting starch, and heating and gelatinizing to obtain plant starch; and (3) mixing the plant fiber pulp, plant starch, sorbitol and microcrystalline cellulose in parts by weight, integrally forming by adopting a molding process, or preparing a plate by adopting a mould pressing process, and then cutting and assembling to obtain the plant fiber composite material. A traditional cinerary casket pursues firmness, durability and long-term preservation, but the cinerary casket adopts an opposite design concept, pursues rapid and natural degradation, enables the departed to really enter the soil and return to the nature, saves land and resources, is green and environmentally friendly, and is suitable for ecological burying scenes such as tree burying, flower bed burying, lawn burying, river burying, lake burying, seawater burying and the like.

Description

Technical Field

[0001] The present invention relates to the technical field of civilian funeral supplies, and more particularly to a naturally degradable green ecological urn and a preparation method thereof. Background Art

[0002] Existing traditional urns are mostly made of hard, non-biodegradable materials such as wood, ceramic, and crystal. These materials not only occupy land resources but also have long-term negative impacts on the ecological environment. Even if some materials are somewhat biodegradable, their degradation cycle is relatively long, hindering the promotion of ecological burial concepts.

[0003] Therefore, how to develop an urn product that is environmentally friendly, quickly degrades, and is easy to recycle naturally to adapt to the development trend of green funerals is an urgent problem that technicians in this field need to solve. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a naturally degradable green ecological urn and a preparation method thereof to address the deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A naturally degradable green ecological urn, characterized by comprising the following raw materials in parts by weight: 20-50 parts of plant fiber slurry, 8-12 parts of plant starch, 2-3 parts of sorbitol and 1-2 parts of microcrystalline cellulose.

[0007] In this invention, plant fiber slurry is the primary ingredient, plant starch serves as a natural bonding enhancer, sorbitol prevents starch aging, and microcrystalline cellulose retains moisture for easier demolding. These four ingredients interact synergistically, significantly enhancing the strength, toughness, smoothness, and moldability of the resulting material. Furthermore, within the aforementioned ratio range, the molded material effectively improves the finished product's structural strength, density, surface smoothness, and moisture resistance, making it suitable for single-shot molding.

[0008] Furthermore, the above-mentioned naturally degradable green ecological urn includes the following raw materials in parts by weight: 50 parts of plant fiber slurry, 8 parts of plant starch, 3 parts of sorbitol and 1 part of microcrystalline cellulose.

[0009] Furthermore, the above-mentioned naturally degradable green ecological urn includes the following raw materials in parts by weight: 40 parts of plant fiber slurry, 10 parts of plant starch, 3 parts of sorbitol and 2 parts of microcrystalline cellulose.

[0010] Furthermore, the above-mentioned naturally degradable green ecological urn includes the following raw materials in parts by weight: 20 parts of plant fiber slurry, 12 parts of plant starch, 2 parts of sorbitol and 2 parts of microcrystalline cellulose.

[0011] Furthermore, the plant fiber pulp is at least one of tree branch pulp, bamboo pulp, reed pulp, bagasse pulp and crop straw pulp.

[0012] Furthermore, the plant starch is at least one of corn starch, wheat starch, rice starch and potato starch.

[0013] A method for preparing the above-mentioned naturally degradable green ecological urn specifically comprises the following steps:

[0014] (1) hydrolyzing and pulping at least one of tree branches, bamboo, reeds, bagasse, and crop straw to obtain plant fiber pulp;

[0015] (2) extracting starch from at least one of corn, wheat, rice, and potato, and heating and gelatinizing the starch to obtain plant starch;

[0016] (3) Plant fiber pulp, plant starch, sorbitol and microcrystalline cellulose are mixed according to weight, and the mixture is integrally formed by a molding process, or the mixture is made into boards by a molding process and then cut and assembled to obtain a naturally degradable green ecological urn.

[0017] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Traditional urns pursue durability and long-term preservation, while the naturally degradable green ecological urn of the present invention adopts the opposite design concept, pursuing rapid natural degradation, so that the deceased can truly rest in peace and return to nature, saving land, saving resources, and being green and environmentally friendly. It is suitable for tree burial, flower bed burial, lawn burial, as well as ecological burial scenes such as river, lake, and sea water burial. BRIEF DESCRIPTION OF THE DRAWINGS
