[0001] DESCRIPTION

[0002] A BINDER-CONTAINING FORMULATION AND A PREPARATION METHOD OF THIS BINDER-CONTAINING FORMULATION

[0003] Technical Field of the Invention

[0004] The invention relates to a molasses-added binder-containing formulation for use in the production of wood-based composite boards, which provides cost savings and environmentally friendly production, as well as a preparation method of this bindercontaining formulation.

[0005] State of the Art

[0006] Wood-based composite boards have a wide range of uses in the building and furniture industry. The binders used in the production of these boards have a direct impact on critical elements such as cost, environmental impacts, and performance. However, it is often not possible to find a balanced solution between cost optimization, environmentally friendly properties, and high performance in traditional binder technologies. In this context, it is crucial to develop new binder solutions that can both reduce costs and provide environmentally friendly and sustainable properties in production processes.

[0007] In the state of the art, the costs of conventional binders used in the production of woodbased composite boards are an important expense item in the production process. These binders are limited in providing optimization in terms of cost.

[0008] In the present art, the binders used in the production of wood-based composite boards are usually based on chemical compounds of non-biological origin. This limits the ability of binders to be environmentally friendly and biocompatible. Nowadays, many materials of organic origin have started to be used in the contents of binder formulations to address said problem; however, these binder formulations exhibit low performance in terms of environmental sustainability and do not provide sufficiently effective alternative solutions without increasing costs, even if based on renewable resources. One of the most important reasons for this is that in the present art, traditional binders used in the production of wood-based composite boards cannotprovide a sufficient reduction in free formaldehyde release in terms of compliance with environmental and health standards without increasing the product cost. This is a huge obstacle, especially in meeting modern environmental regulations and user demands.

[0009] In order to eliminate all these limitations in the state of the art, it is necessary to introduce a binder-containing formulation for use in the production of wood-based composite boards and the preparation method of this binder-containing formulation.

[0010] Summary and Objects of the Invention

[0011] The invention describes a molasses-added binder-containing formulation for use in the production of wood-based composite boards, which provides cost savings and environmentally friendly production, as well as a preparation method of this bindercontaining formulation. The invention aims to introduce a binder-containing formulation capable of maintaining the physical and mechanical properties of wood-based composite boards at a high level, while reducing the amount of free formaldehyde by up to 70%. Furthermore, another object of this invention is to propose an economical binder-containing formulation in the production of wood-based composite boards. Within the scope of the invention, a binder-containing formulation with high biobinding properties is created, thus enabling an environmentally friendly production process. In this way, a binder-containing formulation is made possible that both supports environmental sustainability and provides economic advantages.

[0012] The object of the invention is to provide a binder-containing formulation that reduces the amount of free formaldehyde used therein by up to 70% and still maintains the physical and mechanical properties of the wood-based composite boards in which it will be used at very high levels. Said technical effect is provided by the interaction of sugars, organic acids, and minerals contained in molasses with lignin. Lignin, thanks to its phenolic structure, is able to react with various functional groups. Reactions such as esterification and condensation between molasses components and lignin occur under temperature and pressure. The sugars and organic acids in the contents of molasses interact with the phenolic groups of lignin to form cross-linking, and such chemical reactions contribute to making lignin suitable for adhesives and composite materials. In addition, said technical effect is demonstrated by chemical reactions formed between molasses and formaldehyde-based binders.Another object of the invention is to provide a low-cost binder-containing formulation for use in the production of wood-based composite boards. The low cost of the binder content in the invention is ensured by being able to obtain molasses at one-third of the cost of urea formaldehyde glue, which is the cheapest formaldehyde-based binder, and being able to reduce the use of binders by three times the amount of molasses used.

[0013] The invention provides a binder-containing formulation for use in the production of wood-based composite boards, which exhibits a high level of biobinding property. In the invention, a formulation exhibiting a high level of biobinding properties is provided by the addition of molasses. This is due to a series of chemical reactions that occur between molasses and the chemical structure of wood, which is the main raw material of wood-based material, and increase cross-linking.

[0014] The invention provides an economical, environmentally friendly binder-containing formulation for use in the production of wood-based composite boards.

[0119] 5 The bonding mechanism of molasses works in different ways in acidic and basic media. For example, when magnesium oxide, calcium oxide or hydroxides are used, they react with the saccharide in molasses to form calcium or magnesium saccharates. This reaction takes place at room temperature and in a short time. However, the product produced with this binder is easily soluble in water. Due to its easy and cheap 10 nature, it has been widely used in the production of briquettes from powdered coal.

[0120] However, since the obtained charcoal briquettes quickly disintegrate when in contact with moisture, they are bagged to be stored and put into use.At relatively low pH (between 7-10), the binding mechanism of molasses takes place via the Maillard reaction. In this reaction, the mechanism works through NH2- groups in proteins and amino acids in molasses. The reaction is completed by the conversion of the reduced sugar in the molasses into melanoid structure. When the molasses binder product prepared in this way is compared with the products produced with molasses binder based on the formation of calcium and magnesium saccharates, it is observed that the final product is relatively more water resistant. For this reason, when more water-resistant products are desired, it is preferred that the pH of the molasses binder is between 7-10.

[0121] The reactions of molasses in acidic media (pH 7 and lower) are based on the principle that esters are formed over carboxylic acids at the end of the interaction of acid and molasses, and then these esters give condensation reaction (water output) with the effect of temperature. At the end of the condensation reactions of the resulting esters, C-C cross-links are formed and solid, water-insoluble structures are formed. In other words, if it is desired to obtain water-insoluble, durable products, it is necessary to take advantage of the acidic mechanism at low pH. In the light of this information, this polymerization reaction mechanism of molasses in acidic medium was used in the study. Acidic media can be provided in two ways. These are provided with ammonium salts of strong acids known as latent acids or directly with strong acids. The ammonium salts of strong acids, known as latent acids (such as diammonium phosphate, monoammonium phosphate, ammonium sulfate, ammonium nitrate, ammonium chloride, etc.), decompose under the effect of heat, forming ammonia and strong acids. As ammonia is removed from the medium, the pH of the medium gradually decreases. However, it is not possible to reach pHs that can be reached directly with strong acids. Since the pH of the medium gradually turns into acid, it is also possible to obtain relatively water-insoluble products.
