Description

Leaf regeneration compact board and manufacturing method thereof

The present invention relates to the field of dense boards, especially dense boards using leaf regeneration and a manufacturing method thereof.

Because of its good texture, warm nature, and natural visual effects, wood is often used as a material for construction, decoration and furniture. However, with the rapid development of the industrial and commercial society, the increase in population has caused a sharp increase in the use of wood. Therefore, human A large amount of deforestation not only damages the natural environment, but even affects the survival of protozoa. Although the production of dense boards made of wood chips can help reduce the amount of wood used, trees still need to be felled.

In addition, the leaves of trees will fall after a certain period of time. If they are near cities, parks, roads, homes, and offices, they must be cleaned up, collected, and then discarded, incinerated or buried. This wastes precious resources, not to mention. If the fallen leaves full of mountains and valleys in the forest can be used, it will certainly help reduce the problem of deforestation. Therefore, if fallen leaves or trimmed leaves can be used as the raw material of the dense board, the aforementioned waste of natural resources can be solved, and the natural environment can be protected.

The present invention provides a method for making a leaf regeneration dense board, which includes The following steps: A. Mix the epoxy resin and hardener into glue, the ratio of epoxy resin and hardener is between 2:1 to 4:1; B. Mix the glue and water of step A into glue Mixture, the ratio of water and viscose is between 1:3~1:4; C. Mix the glue mixture and leaf powder of step B into a glue leaf mixture, and the ratio of the glue mixture and leaf powder is 1:0.8~1 :1, the particle size of the leaf powder is between 16-50 mesh; D. The glue leaf mixture of step C is formed into dense board by hot pressing.

The above-mentioned production method of leaf regeneration compact board, wherein, the method is to press molding with a mold, the pressure is 25~50kg/cm ² , the pressure time is 3~5 minutes, and the film is released after molding and heated , The heating temperature is between 100℃~110℃, and the heating time is 20~26 hours.

The above-mentioned leaf regeneration dense board manufacturing method, wherein the leaf powder particles are 30 meshes.

In the above-mentioned method for producing the leaf regeneration compact board, the leaf powder is formed by mixing more than two kinds of particles of different sizes.

The above-mentioned leaf regeneration dense board manufacturing method, wherein the leaf powder is composed of 30-mesh and 16-mesh particles, and the ratio is 85%: 15%.

The above-mentioned leaf regeneration dense board manufacturing method, wherein the leaf powder is composed of powder of 50 mesh, 16 mesh and 30 mesh particles, and the ratio is 10-15%: 10-15%: 70-75%.

The present invention also provides a leaf regeneration compact board, which is composed of the aforementioned method Made by law.

The invention can use fallen leaves or trimmed leaves as raw materials to make dense boards, which can reduce deforestation and resource waste, and minimize damage and damage to the natural environment.
