摘要:
A wax-resin composite is made by melting thermoplastic hydrocarbon resin, optionally with an antioxidant. The melted thermoplastic hydrocarbon resin and waxes are blended at a temperature sufficient to melt the waxes. After blending and melting, the blended thermoplastic hydrocarbon resin and waxes are allowed to solidify. Solidification is followed by post-processing the wax-resin composite mixture to form slabs, pastilles, flakes or other forms. A method for producing a wax-resin composite comprises at least partially solvating a thermoplastic resin in a solvent to form a resin-solvent blend. This may be done at a heat of 80-85° C. A composition of molten wax is blended with the resin-solvent blend. The resin-solvent blend and a molten wax are blended to form a wax-resin blend. This is followed by removing the solvent from said wax-resin blend.
