<p>Composite material that seales the asbestos fibres, obtained by embedding in plastics waste, such as plastic material wastes, asbestos-cement, grinded wastes of asbestos-cement having good workability, intended to obtain manufactured goods. The composite material comprises: a matrix made of a plastic selected from the group consisting of PVC, PE, PP or PET, and grinded asbestos-cement, preferably 20% by weight, the grinded asbestos-cement having a granulation of 2 micrometers-0,4 mm, preferably 2-5 micrometers. Composition containing the above-mentioned composite material and one or more adhesives, optionally chrysotile fibres, and alumina. The invention also refers to a process of obtaining the composite material by injection into the die, which consists of mixing the plastic materials granules together grinded asbestos-cement, bringing to the melting temperature of the plastic material, mixing of the mixture, pressure casting into a die with material tail/cushion and cooling the composite product in the die.</p> |
