Description

DESCRIPTION

Biomaterial

TECHNIQUE SECTOR

The present invention refers to a biomaterial that is obtained from resin pine trees, and which could be classified as a bioplastic.

The object of the invention is to provide a biodegradable ecological product, which can be given very different shapes to obtain all types of objects.

It is therefore a product that allows us to take care of the environment, highlighting all the benefits that trees are providing us, both those we know and those we were unaware of until now, but which are extremely important for human beings and nature.

BACKGROUND OF THE INVENTION

As is known, without trees, the life of living beings on earth would be impossible, since they are the ones that supply the oxygen so necessary to breathe. They are also responsible for cleaning harmful gases, help to hold the land with their roots, prevent desertification and, above all, provide shelter to countless species of living beings, which if it were not for them would not exist, they help regulate the temperature of the planet. etc

In addition to everything previously described, depending on the species of tree in question, human beings take advantage of other raw materials, very important for the development of civilization.

The invention falls within the sector of exploitation of resin pines which, as the name indicates, its resin has been a highly coveted raw material since time immemorial, as well as its wood.

Although these elements have been used to date for the waterproofing of containers or boats in the case of resin, as well as for construction, in the case of wood, the existence of composite biomaterials based on these elements is not known. just like the biomaterial that will be described below.

Thus, the reality is that when it comes to requiring materials that can be easily molded, the usual thing is to resort to plastics which, as is well known, pose a great environmental problem due to their slow biodegradation process (between 100 and 1000 years). .

EXPLANATION OF THE INVENTION

The biomaterial that is recommended completely satisfactorily resolves the previously mentioned problem, based on a simple but extremely effective solution, making the extraction of natural resin profitable, creating sustainable materials with which to gradually remove such single-use plastics from the market. pollutants for our planet.

To this end, and more specifically, the biomaterial of the invention is obtained from three main components, rosin, lignin and water-based varnish.

Rosin is a natural product obtained by distillation of oleoresin, collected from pine trees. It has a solid, hard and brittle appearance, shiny and translucent, amber in color.

It is composed of percentages of abietic, neoabietic, primaric, levopimaric, isopimaric acids, etc.

It is an element that, subjected to certain temperatures, adopts a liquid state and when it decreases, it solidifies quite well.

The entire traceability process of the rosin, from the tree, through the workers, including the final products where it is used, will be traced and guaranteed.

The second component, lignin, is obtained from dry wood sawdust, which will be ground so that when mixed with the rest of the components, it remains homogeneous.

Next we will add it to the mixture, grinding everything and mixing it, so that it mixes correctly.

Depending on the items to be manufactured, the mixture may be more or less ground, to guarantee the strength of the fibers.

The next step is to raise the temperature, so that the rosin molecules change and if it becomes liquid, in this way they interact with the sawdust molecules and of silicon and an agglutination occurs that unites all the molecules into a new biomaterial.

The heating process of the mixture varies depending on the quantity and thickness, ranging from 5 to 10 minutes, depending on the necessary temperature.

Once heated and agglutinated, we are left with a moldable material as long as it does not cool, so it can be given the desired shape by injecting it into a mold and applying pressure.

Once the biomaterial is prepared, it is ready to be pressed into the final form.

In this sense, it is a material that can be shaped, so that it can be used to manufacture elements that we can use in the preparation of gardens and seedbeds, always knowing that the container in which we plant can be left on the ground. , since it will biodegrade and will not produce any pollution.

From this biomaterial, the shapes are endless, since it can be formatted very easily.

Regarding the composition in weight percent of the material described, this will be the following:

Rosin.............. between 45 and 55%

Lignin.................. between 40 and 50%

Water-based varnish......between 2 and 8%

In this way, a supermaterial is obtained capable of biodegrading once its life cycle ends, which can be reincorporated into nature without creating contamination for it.

EXAMPLE OF PRACTICAL REALIZATION OF THE INVENTION

As an example, to prepare 10 kilograms of biomaterial for the formation of food bowls, the following components were used:

Rosin..........................5000 grams.

Lignin...............................4500 grams.

Water-based varnish.............. 500 grams.

The rosin and lignin will be ground into powder.

These components were then mixed together, to put the resulting product in a hot press or in a printer, with which the final shape was given, in this case containers, so that once obtained a final layer was applied to them. of water-based varnish, so that in addition to protecting the surface, the manufactured model serves to receive food, fruits and other consumer products.
