Polyurethane composite material, preferably in the form of shaped blocks for applications in hydroengineering for construction of flood banks and/or reinforcement of berths and method for producing it

摘要

the object of the application is composite, containing phosphogypsum; fly ash, boiler dust and slag, which is characterized by the fact that additionally contains from 1% to 50% parts by weight of rubber and 1% - 30% by weight of polyurethane, and water in quantities dopeu0142niaju0105cej to 100% by weight.the subject application is also a way of composition, which is that preparing a mixture consisting of from 1% to 40% by weight fosfogipsu, from 1% to 40% by weight of volatile, 1% to 40% by weight of boiler dust and slag, and from 1% to 50% by weight of gr anulatu rubber, and then to the weight of the mixed favourably at 30 - 60 rpm,the following dwusku0142adnikowu0105 mass of polyurethane polyols and isocyanates in which mixture mixture ratio 2: 1, the whole is mixed in a gas mixing piece and wtu0142aczana to appropriate forms of steel to perform appropriate of composite.
