Abstract
A method for producing a lignocellulose plastic composite material, in particular a simpler and more cost-effective option for producing lignocellulose plastic composite materials. Thermoplastic particles and a mixture of water and lignocellulose-containing particles are supplied to a refiner, and the lignocellulose-containing particles are reduced to fibers in the refiner. The thermoplastic particles are supplied to the refiner in a melted or fused state, or are melted or fused in the refiner, so that the melted or fused thermoplastic particles and the lignocellulose-containing particles that are reduced to fibers form material composite particles in the refiner.
Claims10
A method for producing a lignocellulose-plastic composite material, wherein
- thermoplastic particles and a mixture of water and lignocellulose-containing particles are fed to a refiner, and
- the lignocelluslose containing particles are reduced to fibers in the refiner, and wherein the thermoplastic particles melted or pre-melted only in the refiner so that the melted or pre-melted thermoplastic particles and the lignocellulose-containing particles that have been reduced to fibers than material composite particles in the refiner, and wherein the thermal energy required to melt or partially melt the thermoplastic particles is generated exclusively by (a) shearing energy in the refiner, (b) heating the refiner by electric heating or (c) by a combination of shearing energy in the refiner and heating the refiner by electric heating.
