Title: Coating and construction material and applications thereof
IPC: B22C9/04
Filed: 1997-04-28
Abstract: 1. A construction, moulding or coating and/or impregnation material of the type "modified wax", preferably based on paraffine wax which, e.g. by admixture of polymers, exhibits increased hardness and a higher melting point than natural wax, characterized in that the wax material is so widely modified by means of environmentally neutral additives that it appears as a hard material, with a penetration value below 6, preferably in the range 0.5-4, according to ATSM standard D 1321, or, respectively, with a melting point above 70 degree C, preferably in the range of 80-120 degree C. 2. A material according to Claim 1, characterized in that it appears as a plate or block material for further machining into utility objects. 3. A material according to Claim 1, characterized in that it appears in a moulded shape as a utility object, optionally in admixture with filler material. 4. A material according to Claim 1, characterized in that it appears as a corrosion protective coating material on surfaces of other materials such as concrete, metal or wood. 5. A material according to Claim 1, characterized in that it appears as a granular material for moulding or laying out, with or without incorporated filler material. 6. A material according to Claim 1. characterized in that it appears as a fully or partly surrounding film coating on particles of other materials, which are desired to deliver active substances in a retarded manner. 7. A material according to Claim 6, characterize in that it appears as a coating on granular material such as artificial fertilizers, washing powder, road salt or other materials with a desirable long term effect. 8. A material according to Claim 1, characterized in that it appears as a melting fuse material in connection with fire or overheating. 9. A material according to Claim 1, characterized in that it appears as a coating on particles to be bonded together by heating to melt the wax. 10. A material according to Claim 1, characterized in that in connection with filler material it forms an air permeable, porous barrier against intrusion of water with surface tension. 11. A material according to Claim 1, characterized in that it is in admixture with graphite or iron oxide and, optionally, with earth colours or fat colours. 12. A material according to Claim 1, characterized in that it appears as a powder or as an aqueous emulsion. 13. An application of a material according to Claim 1, characterized in that it is used in the manner or with the purpose specified in any of the Claims 2-11. 14. An application according to Claim 13, characterized in that the material according to Claim 6 is used for full or partial encapsulation of granular fertilizers, weed killers, road salt, washing powder or drugs. 15. An application of the material according to Claim 1, characterized in that the material in admixture with moulding sand or other or further fillers is used for making mould or core elements for use in metal casting, such elements after use being reproduced by remelting of the wax for renewed use. 16. An application according to Claim 13, characterized in that the material according to Claim 11 is used, with a desired colour, for coating of sand or other granular materials adapted to be laid out on tennis courts or at other relevant areas, optionally in flower bowls.
