摘要

Production of composite materials of thermoplastic matrix with the addition of poly (vinyl butyral (PVB)) and glass particles from the process of mechanical separation of laminated glass.This patent relates to the use of poly (vinyl butyral) and particles of glass, both from the process of mechanical separation of laminated glass, such as charges for thermoplastic matrices.The addition of these two types of cargo to a thermoplastic matrix aims to increase the property of impact resistance of the matrix.Without the loss in stiffness typically observed when only material borrachoso, PVB,Is incorporated into the matrix to obtain the composite thermoplastic matrix / PVB / glass particulates were used standard procedures of mixing and molding, such as mixers.Single or double screw extruders and injection moulding or compression. The various particle size distributions of glass particles are used, all with a particle size below 150 109 M.The fractions of PVB in the composite ranging from 5 to 50% by weight, and the fraction of glass particulates varied according to the fraction of PVB is used.The present invention is exemplified by the use of polyamide - 6 as a matrix, resulting in a composite with impact resistance of 300% higher than in the matrix, and the rigidity.The inferred by the modulus of elasticity, remained unchanged.In addition, is substituted for virgin raw materials and high added value, for recovered materials, which now are an environmentally friendly destination.
