Description

The present invention relates to a method for producing a hybrid polymer material and a hybrid polymer material produced according to this method. Hybrid polymers are polymeric materials that combine structural units from different material classes at the molecular level and possess special properties and functionalities due to their composition. Such materials are frequently produced using the sol-gel process. Because of the unique properties of these materials, which often represent a combination of properties of the starting materials not readily available elsewhere, there is great interest in such hybrid polymeric materials and corresponding production processes, which should be as simple and easily adaptable as possible. DE 10 2017 107 591 A1 describes a process for producing a hybrid polymer material in the form of an artificial stone by reacting a polymer resin with at least one Si compound selected from silanes, siloxanes, silazanes and silicone resins, as well as an inorganic solid and auxiliary materials to form a raw mass, which is then compacted and hardened. WO 97/39043 A1 This mostly concerns foamed polyester polyurethanes used in the production of lightweight components. The polymer contains a high proportion of fillers, which are surface-treated with a liquid reactive component in a preliminary step. JP 2014-210843 A This concerns the production of a plastic housing for semiconductor components. A mixture of various polymer resins is used, consisting essentially of a thermosetting resin A, a fluoropolymer C, an inorganic filler D, and a catalyst B. The resin A is preferably silicon-based or epoxy-based and can also consist of a mixture of different resins. It is therefore an object of the present invention to provide a method for producing a hybrid polymer material which is based on the use of inexpensive starting materials and is as easy to carry out as possible and leads to new hybrid polymer materials with advantageous properties. The present problem is solved by a method according to the attached claim 1. A hybrid polymer material according to claim 8 is also the subject of the present invention. Advantageous embodiments of the invention are the subject of the directly or indirectly referenced claims. It should be noted that this description uses references to commercially available products whose composition is generally not disclosed in detail by the manufacturer, as these compositions are considered trade secrets. Furthermore, singular and plural forms of a term are used interchangeably in the description and the claims, and the mention of the singular, e.g., "solid," includes the plural, e.g., "solids," and vice versa, since the solid contained in the manufactured raw material can, for example, be named in its entirety, but may in fact be composed of various solids differing in type and/or size. Within the scope of the present invention, a "solid of a different type" refers to a solid that differs from another solid in terms of structure and/or material class; for example, a polymeric solid is a solid of a different type compared to a mineral solid or a rock. In the inventive process for producing a hybrid polymer material based on a reactive polymer resin and one or more silicon compounds from the group comprising silanes, siloxanes, silazanes, and silicone resins, a mixture of various solids, differing in type and optional size, in combination with the reactive polymer resin and one or more silicon compounds as well as additives, forms a raw material. This raw material is compacted and subsequently reacted and cured. Curing is achieved, for example, by heat treatment at a temperature in the range of room temperature to 350 °C, by a radical chain reaction, or by UV irradiation. The reaction typically occurs within the raw material during curing. In the presence of metals, autocatalytic or metal-catalyzed, and at least partially exothermic, reactions also occur. During the investigations carried out within the scope of the present invention, it was unexpectedly found that practically any solid can be integrated or incorporated into the hybrid polymer material according to the invention and, depending on the particle size and/or quantity used, can exert special effects in a controllable manner. According to the invention, the solid material is a mixture of various solids of the same type, containing a particulate fluoropolymer and a particulate thermoplastic polymer, wherein the proportion of the mixture of various solids of the same type is 40 to 97 wt.% of the total mass of the raw material and the proportion of the thermoplastic polymer is at least 56 wt.% of the total mass of the raw material. In addition, up to a maximum quantity of all solids of the mixture of 97 wt.% of the total mass of the raw material, a wide variety of materials can be used as further solids according to the invention, in particular particulate polymers selected from the group comprising thermosets, elastom
