Definitions
- the invention relates to components, moldings and components which are used in areas and applications in which questions of fire protection play an important role.
- thermosets used can be processed in conventional different ways. It is also possible to carry out the processing in stages with partial and later final curing.
- thermoset is epoxy resin, expediently in pure form.
- the dry, powdery filler is mixed in as large a proportion as possible, advantageously 50% by weight or more, of the plastic mass in such a way that the surface of the extinguishing particles are protected against moisture effects by a thermoset film.
- thermosets such as phenoplasts or aminoplastics, can also be used.
- the choice of powder is to be made according to the application requirements.
- the national or international fire classes and the powdered extinguishing agents approved for these fire classes can serve as a guide.
- Powder mixtures containing potassium and / or sodium hydrogen carbonates and / or contain potassium sulfates are flammable liquids or gaseous substances that may escape under pressure.
- the powder can also consist of mixtures of ammonium phosphate and ammonium sulfate.
- the extinguishing particles are present in a dense packing. Since they are firmly integrated into the thermoset matrix, they maintain their fixed position even under the direct action of flame. It is important to have the largest possible active surface. Therefore, powders are made with extremely small extinguishing powder particles that are extremely large
- Number per unit volume is preferred.
- the concentration of the extinguishing powder particles is particularly high, especially in the area of the free surface of the shaped body, the component or the coating.
- This can be achieved in a simple manner during production or molding by compressing the extinguishing-active particles in the molded or applied plastic mass by means of compression pressure and / or vibration, while at the same time the excess or excess amount of thermosetting plastic in the area of the surface is suctioned off or otherwise removed become.
- This can be achieved in a simple and effective manner, for example, with the aid of a removable film which is permeable to the thermoset and a nonwoven layer absorbing the thermoset.
- the active extinguishing particles in the exposed surface are then only from a film which reliably protects the particles against the influence of moisture.
- the plastic mass usually contains no other fillers apart from the active powder.
- the active extinguishing fillers give the thermosetting plastic an increased rigidity and surface hardness as well as an improved abrasion resistance.
- the burning rate of the hardened plastic mass is slow and is, for example, only about 1 mm per minute with direct exposure to a burner flame of approx. 1200 ° C.
- the ambient temperature on the plastic mass can e.g. Rise 1000 ° C.
- the mass also acts reliably and immediately self-extinguishing. It is also possible to spray the plastic compound as a thin coating onto self-combustible or glowing substances such as wood, paper (phenol-impregnated paper honeycomb), foam, plastic or the like, or to apply it in some other way in order to effectively counteract the action of flames to protect.
- the plastic mass can be processed in the usual ways for thermosets and, if necessary, reinforced with glass fibers or the like.
- the free surface can be structured in any desired manner, painted or coated with decorative material made of textile or paper or the like. It is also of no importance whether these materials themselves, which are only in a thin layer, are flammable.
- the plastic mass leads to form-retaining self-supporting shaped elements, into which e.g. construction elements used for assembly can be embedded or used.
- the self-extinguishing plastic mass can be pre-consolidated cold and hardened by heating, which in many cases makes processing easier.
