Environment-friendly coffin manufacturing process based on foaming process and environment-friendly coffin

Abstract

The invention discloses an environment-friendly coffin manufacturing process based on a foaming process and an environment-friendly coffin. A formula of the environment-friendly coffin comprises the following components in parts by mass: 70-80 parts of modified starch; 8-15 parts of bamboo fiber; 2-5 parts of a foaming agent; 8-15 parts of a biological mineral filler; 1-4 parts of a release agent; during preparation, the raw materials are measured according to the components of the formula, and the preparation method comprises the following steps: a, pretreating the bamboo fibers to meet the use requirements; b, modifying the starch to increase the cohesive force and the mechanical property; c, grinding, calcining and sterilizing the biological mineral filler; d, mixing and uniformly stirring the modified starch, the bamboo fiber and the biomineral filler in a mixing barrel; adding a foaming agent and water, and continuously stirring at a high speed to form a uniform material block; e, placing the material block in a coffin mold, preheating the coffin mold, and maintaining the pressure through a pressing machine after preheating is completed; f, opening an exhaust hole in the coffin mold, and removing water vapor in the coffin mold; g, the formed coffin is dried, so that the stable shape and the proper water content of the coffin are kept. The method has the advantages that the formed product is environment-friendly and pollution-free and can be quickly and completely degraded.
