A method for making an environment-friendly coffin by using waste corrugated paper and straw

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 manufacture, and in particular relates to a method for manufacturing an environment-friendly coffin by using waste corrugated paper and straw. Background technique

[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. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for manufacturing an e...

Examples

Embodiment 1

[0018] The straw is pulverized into 120-150 mesh; the waste corrugated paper is pulverized by a pulper to form a slurry, and the paper fiber used as the raw material of the environmental protection coffin is screened out through a 2.0mm hole screen; the raw materials are proportioned according to the weight percentage, and the pulverized straw 30%, dried paper fiber 40%, 5% adhesive, and the rest are auxiliary materials; after the proportioning, it is evenly stirred and sent to a molding machine to form a semi-finished coffin bottom plate, four side plates and For the coffin lid, control the temperature in the compression molding machine at 110°C-130°C. The surface of the semi-finished coffin bottom plate, four side panels and the coffin lid is veneered, and the veneer paper is mainly plastic paper or wood paper; the coffin bottom plate, four side panels and coffin lid after veneering are assembled and bonded to form coffin. The spliced ​​coffins are air-dried.

[0022] The straw is pulverized into 120-150 mesh; the waste corrugated paper is pulverized by a pulper to form a slurry, and the paper fiber used as the raw material of the environmental protection coffin is screened out through a 2.0mm hole screen; the raw materials are proportioned according to the weight percentage, and the pulverized straw 32.5%, dried paper fiber 45%, 7.5% adhesive, and the rest are auxiliary materials; after proportioning, it is evenly stirred and sent to a molding machine to form a semi-finished coffin bottom plate, four side plates and For the coffin lid, control the temperature in the compression molding machine at 110°C-130°C. The surface of the semi-finished coffin bottom plate, four side panels and the coffin lid is veneered, and the veneer paper is mainly plastic paper or wood paper; the coffin bottom plate, four side panels and coffin lid after veneering are assembled and bonded to form coffin.
