Problems solved by technology

[0002] Usually the recycled straw and waste corrugated paper will be wasted by people, so it is very necessary to improve the utilization rate of straw and corrugated paper; The waste of wood will cause a large number of trees to be felled; there are some paper coffins on the market. This type of paper coffin still needs to use wood as the base layer and then attach paper to the wood, so wood will still be wasted; combining straw and The utilization rate of corrugated paper is low, so it is necessary to design an environmentally friendly coffin that uses waste corrugated paper and straw as raw materials

Embodiment 1

[0018] Straws are crushed into 120-150 meshes; the waste corrugated paper is crushed by a pulper to form a slurry, and the paper fibers used as the raw materials of environmentally friendly coffins are screened through a 2.0mm sieve; the raw materials are proportioned by weight percentage, and the crushed straw 30%, 40% of the dried paper fiber, 5% of the adhesive, and the rest are auxiliary materials; after the proportioning, it is evenly stirred and then sent to the molding machine for molding to form a semi-finished coffin bottom plate, four side plates and For the coffin cover, the temperature in the compression molding machine is controlled at 110℃-130℃. The semi-finished coffin bottom plate, four side panels and the surface of the coffin cover are veneered. The paper for the veneer is mainly plastic paper or wooden paper paste; the coffin bottom plate, four side panels and coffin cover after the veneer are assembled and bonded to form coffin. Air-dry the spliced ​​coffin...

Embodiment 2

[0022] Straw is crushed into 120-150 mesh; the waste corrugated paper is crushed by a pulper to form a slurry, and the paper fiber used as the raw material for environmentally friendly coffins is screened through a 2.0mm sieve; the raw materials are proportioned according to the weight percentage, and the crushed straw 32.5%, 45% of the dried paper fiber, 7.5% of the adhesive, and the rest are auxiliary materials; after the proportioning, it is evenly stirred and then sent to the molding machine for molding to form a semi-finished coffin bottom plate, four side plates and For the coffin cover, the temperature in the compression molding machine is controlled at 110℃-130℃. The semi-finished coffin bottom plate, four side panels and the surface of the coffin cover are veneered. The paper for the veneer is mainly plastic paper or wooden paper paste; the coffin bottom plate, four side panels and coffin cover after the veneer are assembled and bonded to form coffin.

Abstract

The invention discloses a method for manufacturing an environment-friendly coffin through waste corrugated paper and straw. The method comprises the process flows of pretreatment of raw materials of the environment-friendly coffin, proportioning of the raw materials of the environment-friendly coffin, manufacturing of a core layer of the environment-friendly coffin, surface mounting of the core layer of the environment-friendly coffin, molding of the environment-friendly coffin, and air drying treatment. The corrugated paper, the straw and auxiliary materials are mixed and extruded to form the core layer which is high in strength, and the corrugated paper and the straw can be recycled. By producing the environment-friendly coffin through the raw materials, the cost is greatly reduced, the utilization rate of the corrugated paper and the straw is improved, and tree felling is reduced in disguise.

Description

Technical field [0001] The invention belongs to the field of coffin manufacturing, and particularly relates to a method for manufacturing an environmentally friendly coffin using waste corrugated paper and straw. Background technique [0002] Usually recycled straw and old corrugated paper will be wasted by people, so it is very necessary to increase the utilization rate of straw and corrugated paper; the existing cremation coffins are usually made of a large amount of wood as raw materials, and such coffins will be made in large quantities. The waste of wood will cause a large number of trees to be felled; there are some paper coffins on the market. This type of paper coffins still need to use wood as a base layer and add paper to the wood, so the wood is still wasted; combined with straw and The utilization rate of corrugated paper is low, so it is necessary to design an environmentally friendly coffin that uses waste corrugated paper and straw as raw materials. Summary of the...
