Abstract
Description
Technical Field
[0001] This invention relates to the field of cremation urn technology, and in particular to a cremation urn and its preparation method. Background Technology
[0003] Cremation urns are generally made of wood, or have jade carvings inlaid on the wall panels or lid, to express people's grief for the deceased.
[0004] In existing technologies, wooden urns are prone to decay and decomposition over time due to their poor corrosion resistance. This causes the ashes inside to scatter and return to the earth without leaving any residue. Consequently, the ashes cannot be preserved for a long period after cremation, let alone be moved as people move around geographically. On the other hand, the ashes are at a high temperature when the body is freshly cremated, and wood has poor insulation properties. This makes wooden urns prone to heat conduction when storing freshly cremated ashes, which is inconvenient for family members to move. Summary of the Invention
[0005] Based on this, the purpose of the present invention is to provide an urn and its preparation method to solve the technical problems of poor corrosion resistance, easy decay and poor heat insulation of the urn in the prior art.
[0006] This invention provides a method for preparing an urn, comprising: A polyvinyl acetate emulsion is obtained and mixed with water to obtain a first raw material; Obtain tile ash, gypsum powder, mother-of-pearl powder, cement, and fine sand, and mix them to obtain the second raw material; The first raw material and the second raw material are mixed to obtain a mixed mud; The mixed clay is poured into the base mold to form multiple structural components, and the multiple structural components are combined to form the base of the urn. The surface of the urn base blank is painted to obtain the urn.
[0007] In addition, the above-described method for preparing a cremation urn according to the present invention may also have the following additional technical features: Furthermore, in the mixed mud, the weight percentage of the first raw material to the second raw material in the total weight is 1:1.
[0008] Furthermore, in the first raw material: the weight percentage of each component in the total weight of the first raw material is: polyvinyl acetate emulsion 70%-80%, water 20%-30%.
[0009] Furthermore, in the second raw material: the weight percentage of each component in the total weight of the second raw material is as follows: tile ash 10%; gypsum powder 10%; mother-of-pearl powder 5%-15%; cement 50%; fine sand 15%-25%.
[0010] Furthermore, prior to the step of painting the surface of the urn base blank, the following steps are also included: Obtain the mixed ash required for scraping; The mixed ash is scraped onto the surface of the urn base blank to obtain the urn after ash scraping; The preparation method of the mixed ash includes: Obtain raw lacquer and tung oil, and mix the raw lacquer and tung oil to obtain a raw lacquer and tung oil mixture; The first gray body is obtained by mixing raw lacquer and tung oil with water; Obtain tile ash and gypsum, and mix the tile ash and gypsum to obtain a tile ash and gypsum mixture; The first ash body is mixed with the tile ash gypsum mixture to obtain mixed ash.
[0011] Furthermore, in the step of mixing raw lacquer and tung oil, the ratio of raw lacquer to tung oil is 2:1; In the step of mixing the raw lacquer and tung oil mixture with water, the ratio of the raw lacquer and tung oil mixture to water is 4:1.
[0012] Furthermore, in the step of mixing tile ash and gypsum: the ratio of tile ash to gypsum is 5:1; In the step of mixing the first ash body with the tile ash gypsum mixture: The ratio of the first gray body to the tile gray gypsum mixture is 1:1.
[0013] Furthermore, in the step of casting the mixed clay into multiple structural components using a base mold, the solidification time of the structural components is 24 hours.
[0014] Furthermore, the thickness of the structural components is 1cm-2cm.
[0015] Another aspect of the present invention provides an urn, prepared using the above-described urn preparation method, the urn comprising: The urn base blank and the protective layer disposed on the surface of the urn base blank, the protective layer including a paint layer, the urn base blank including a plurality of structural components, each structural component including a structural body and a mesh fiber cloth disposed within the structural body, the structural body including a first structure and a second structure disposed on the first structure, the mesh fiber cloth being disposed between the first structure and the second structure.
[0016] The aforementioned urn and its preparation method, by mixing a first raw material with a second raw material to obtain a mixed mud, and then casting the mixed mud to obtain the urn base blank, replaces the existing technology of using wood to make urns. Specifically, adding polyvinyl acetate emulsion to the first raw material helps to improve the viscosity of the mixed mud and improves the structural strength of the urn base blank. Adding cement and fine sand to the first raw material, along with tile ash, gypsum powder, and mother-of-pearl powder, improves the corrosion resistance and heat resistance of the urn base blank. Furthermore, casting the urn base blank by pouring the mixed mud is simple and improves the preparation efficiency of the urn.
