Problems solved by technology

[0002] Most of the coffins currently in use are made of hard wood. Whether it is a coffin for cremation or a log coffin for burial, a large amount of wood is used as a raw material, so it will destroy a lot of forest resources, resulting in an extremely serious environment. Bad, but now there are a lot of waste paper and some waste corrugated paper every year, these waste paper and waste corrugated paper are usually wasted, so it is necessary to design an environmentally friendly coffin made of waste paper and waste corrugated paper, which can not only reduce wood A lot of felling can also improve the utilization rate of these waste corrugated paper and waste paper

Embodiment 1

[0018] Put the waste paper into a pulper and pulverize it, control the pulping concentration of the pulper at 10%, and the operation time of the pulper is 35 minutes to form a waste paper slurry; pass the pulverized waste paper slurry through a sieve The hole is 3.0mm hole sieve for screening, the slurry that passes through the sieve hole is the surface layer slurry, and the one that does not pass the sieve hole is the core layer slurry. After the surface layer slurry is beaten, the paper is made into surface layer paper; Drying treatment, cut the core layer slurry after drying treatment into 40 mesh waste paper powder, add bamboo charcoal powder with a fineness of 140 mesh and heat-sensitive adhesive to the waste paper powder, and mix them to form a mixed core material , control the mass ratio of waste paper powder to 70%, the mass ratio of bamboo charcoal powder to 5%, and the rest are adhesives; the mixed core material is sent to the molding machine to form a semi-finished c...

Embodiment 2

[0020] Put the waste paper into a pulper and pulverize it, control the pulping concentration of the pulper at 11.75%, and run the pulper for 40 minutes to form a waste paper slurry; pass the pulverized waste paper slurry through a sieve The hole is 3.0mm hole sieve for screening, the slurry that passes through the sieve hole is the surface layer slurry, and the one that does not pass the sieve hole is the core layer slurry. After the surface layer slurry is beaten, the paper is made into surface layer paper; Drying treatment, cut the core layer slurry after drying treatment into 50 mesh waste paper powder, add bamboo charcoal powder with a fineness of 150 mesh and heat-sensitive adhesive to the waste paper powder, and mix them to form a mixed core material , control the mass ratio of waste paper powder to 75%, the mass ratio of bamboo charcoal powder to 7.5%, and the rest are adhesives; the mixed core material is sent into a molding machine to form a semi-finished coffin bottom...

Abstract

The invention discloses a method for manufacturing an environment-friendly coffin by utilizing waste corrugated paper. The process flow of the method comprises the following steps of crushing waste paper, screening paper pulp, manufacturing a core layer, forming the core layer, veneering the core layer, forming the coffin and drying the coffin. According to the process of the method, the coffin is manufactured by utilizing the waste paper and the waste corrugated paper, so that a large amount of timber to be cut can be reduced and the utilization rates of the waste corrugated paper and the waste paper can be increased.

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. Background technique [0002] Most of the coffins currently in use are made of hard wood. Whether it is a coffin for cremation or a log coffin for burial, a large amount of wood is used as a raw material, so it will destroy a lot of forest resources, resulting in an extremely serious environment. Bad, but now there are a lot of waste paper and some waste corrugated paper every year, these waste paper and waste corrugated paper are usually wasted, so it is necessary to design an environmentally friendly coffin made of waste paper and waste corrugated paper, which can not only reduce wood A large number of felling can also improve the utilization rate of these waste corrugated paper and waste paper. Contents of the invention [0003] The technical problem to be solved by the ...
