Definitions
- TITLE Method of manufacturing a binder, in particular intended for the preparation and / or coating of aggregates or for use in the composition of matrices for the manufacture of biocomposites.
- the invention relates to a method of manufacturing a binder, in particular for the preparation and / or coating of aggregates or used in the composition of matrices for the manufacture of biocomposites.
- the invention also relates to a method of manufacturing a product using the binder obtained according to the manufacturing method according to the invention.
- the invention further relates to a binder as such and its use for coating aggregates or as a binder of a matrix.
- the invention will find particular application in the building materials or transport industry.
- Proteins are complex macromolecules that can make up 50% or more of the dry mass of living cells. They play a fundamental role in the structure and functions of cells. Each protein is characterized by its conformation, that is, its three-dimensional organization. Proteins consist of amino acids. These contain at least one primary amino group (-NH 2 ) and a carboxylic group (-COOH).
- Natural amino acids have the following structure:
- R is a characteristic side chain of variable composition. It influences the physico-chemical properties of amino acids and, consequently, the properties of the protein that contains it.
- the polarity of the side chain makes it possible to classify the amino acids.
- the solubility of Protein in water depends essentially on the distribution of the polar (charged or non-charged) and apolar (hydrophobic) groups of the side chain of the constituent amino acids.
- amino acids Once the amino acids are dissolved in the water, they can behave according to the pH as an acid (pH ⁇ pl) or a base (pH> pl). These molecules are said to be amphoteric.
- Proteins by their physico-chemical properties are likely to participate, through different functions, in the modification of the environment where they are introduced. There are three main groups of properties:
- Hydration properties dependent on protein-water interactions includes properties such as water absorption and retention, wettability, swelling, adhesion, dispersibility, solubility and viscosity;
- the proteins coagulate in acid medium, they can undergo dehydration more or less important depending on the temperature of the medium. This results in the formation of a rubbery, more or less elastic, heat-hardening proteinaceous mass.
- Some protein substances are available in large quantities and are poorly valued, such as hemoglobin or casein.
- hemoglobin With regard to hemoglobin, it should be noted that the blood collected during the slaughter of animals represents about 3 to 5% of their mass. Annually, the available quantities amount to more than 140,000 tons in Germany, 100,000 tons in Great Britain, 80,000 tons in France. In addition, considerable quantities are often rejected because of the lack of equipment of some slaughterhouses. In France, for example, only 80,000 tons would be recovered from the 200,000 tons produced according to the CTGREF (Technical Center of Rural Engineering of Water and Forests), which can allow to consider negative impacts on the hygienic and economic level.
- CTGREF Technical Center of Rural Engineering of Water and Forests
- proteins Due to their surfactant properties, proteins can adsorb on liquid gas interfaces and promote the formation of a foam. Globular proteins, such as hemoglobin, form a resistant barrier at the liquid gas interface, which prevents the diffusion of gas and the coalescence of bubbles. Previous work has shown that hemoglobin is a very good foaming agent both by its foaming capacity and the stability of the formed foam.
- Mr Ruzicka notably optimized the foaming of clay cement pastes with this foaming agent based on rheological criteria and with the aim of developing insulators and carrier insulators with high environmental quality.
- Nadira Madjoudj's experimental results confirmed the potential value of hemoglobin in the production of building materials.
- hemoglobin as an air-entraining aid has been extended to cement-rubber and cement-polyethylene terephthalate composites.
- Casein is a protein, containing in particular calcium and phosphoric acid, derived from milk.
- the term vegetable casein is assigned to a nitrogenous substance extracted from the cake, oilseed residues after oil extraction.
- the use of pure casein or associated with lime in paints or whitewashes is already known. The main purpose of adding lime is to reduce the cost.
- presolvent of lime for crude casein is also mentioned, like ammonia, ammonium carbonate, borax and potash.
- the use of pure acids, especially undiluted acetic acid, as a presolvent is also reported.
- the crude casein must be added with a "solvent” so that it can then be diluted with water.
- the casein / lime mixture remains “brittle", but it is possible to add a plasticizer.
- glycerine or a vinyl binder is reported.
- Casein added with formalin leads to a very hard substance, galalith. Formalin is also considered as a hardening and waterproofing agent for protein paints.
- vinegar is defined as a condiment liquid obtained by the action of bacteria that transform an alcoholic solution into a solution containing 4 to 12% acetic acid.
- the the most diverse raw materials are used in the manufacture of vinegar: wine, ethyl alcohol (white vinegar), cider, sugar cane, malt, palm wine, dates, oranges, bananas, rice, coconut milk.
- vinegar is produced industrially only from agro resources.
- the object of the present invention is to propose the manufacture of a binder derived mainly or even 100% from agro resources and especially from the abovementioned elements, that is to say hemoglobin, and / or casein, and / or vinegar.
- hemoglobin and casein can be mixed and partially or completely substituted by other compounds of animal or plant origin, such as cakes, cereal flours, potato pulp and vinegar.
- the present invention relates to a process for the manufacture of a binder, especially for the preparation and / or coating of aggregates, or used in the composition of matrices for the manufacture of biocomposites.
- the binder is obtained by mixing, on the one hand, hemoglobin and / or casein and / or other protein compounds of animal or vegetable origin such as, in particular, cakes, cereal flours and potato pulp and, secondly, vinegar and / or any other solution of acetic acid or other organic acids
- hemoglobin can be extracted from animal blood recovered after slaughter.
- the manufacturing method may comprise the following steps:
- the mixture obtained is heated, for example with a moderate heat treatment, in particular by microwaves,
- the mixture is plasticized by adding vegetable oils in variable proportions according to the desired consistency,
- the mixture is mixed in order to create an emulsion or a foam which remains stable after hardening
- a cellular structure can be created by adding an effervescent compound, a preformed foam or an expansive agent such as aluminum powder reacting with lime,
- the mixture obtained, foamed or not may be loaded with lignocellulosic fillers, mineral fillers or polymers of natural or synthetic origin,
- the mixture obtained, foamed or not, whether or not charged may be reinforced by any type of fibers of vegetable, mineral or polymer origin of natural or synthetic origin,
- the mixture, foamed or not, loaded and optionally reinforced, can be shaped by thermocompression, by simple molding (casting), by injection molding, rotational molding, extrusion or any other method of shaping composites ,
- the foamed or non-foamed mixture, loaded and possibly reinforced may be subjected to any mechanical action, such as calendering, intended to form it in the form of thin plates,
- the foamed or uncured mixture, loaded and optionally reinforced may be applied by coating or impregnation,
- the foamed mixture or not, loaded and possibly reinforced, may require drying in the open air or in a ventilated oven or other means of drying.
- Another object of the invention relates to the products obtained by the aforementioned method.
- the binder can then be used:
- binder or binder products according to the invention will find particular application in the building materials and transport industry.
- the products obtained according to the processes described in the present invention can be used in thermal and / or sound insulation, as well as in the construction of building elements, that of various furniture accessories, in the industry. automotive industry, the aviation industry, the rail industry, the toy industry and decoration, packaging, etc.
- Hemoglobin powder whether or not loaded with finely ground vegetable particles, is added with diluted vinegar or not.
- the mixture gives rise to the formation of angular granules which harden at room temperature. Curing can be accelerated thermally or chemically.
- Agroliant can be obtained from hemoglobin powder with added vinegar, possibly diluted in variable proportions, for example from 1 to 10 times by volume, of casein powder, lime and vinegar in variable mass proportions, for example 1 part of lime for 4 parts of casein and 10 parts of vinegar.
- a mixture of casein and hemoglobin can be carried out, for example, in proportions ranging from 1 part of hemoglobin per 8 parts of casein to 4 parts of hemoglobin per 5 parts of casein.
- Cereal flour, and / or potato pulp can be incorporated in the protein mixture in proportions ranging from 5% to 50%.
- the vinegar can be diluted by adding water in proportions ranging from one part of water to one part of vinegar to 10 parts of water to 1 part of vinegar according to the objectives to be achieved.
- the binder thus constituted, emulsified, foamed or not, is added with vegetable fractions in proportions ranging from 1 volume of vegetable fraction per 3 volumes of binder to 10 volumes of vegetable fractions per 1 volume of binder, the proportion of vegetable fraction being limited by the texture of the binder which must allow optimal binding of plant fractions.
- the mixture thus formed can be shaped by thermocompression at temperatures up to 250 ° C and pressures up to 300 bar.
- the binder can be plasticized by adding a vegetable oil, especially for use in gluing or coating woven or non-woven in proportions ranging from 1 to 50%.
