Definitions

  • the invention relates to a method for producing paper foam from waste paper and / or cardboard, wherein this starting material is first worked up to a fiber mass and then mixed with starch, whereupon the mixture is compressed and plasticized by thermal and mechanical energy input in an extruder and exits at the extruder expands or foams due to a drop in temperature and pressure.
  • plasticizable degraded starches flour mixtures with a high starch content, proteins or plastics such as e.g. PVC mixed in.
  • PVC polyvinyl cellulose
  • the mixture used consists of fifty percent cellulose mixed with fifty percent starch.
  • the object of the invention is to further improve this previously known method.
  • PVAL polyvinyl alcohol
  • the specified viscosity was measured in accordance with DIN 53015, a four percent aqueous solution at 20 ° C. According to DIN 51550, the viscosity is a measure of the internal friction that occurs when two adjacent layers of liquid move.
  • the degree of saponification indicates what percentage of the polyvinyl acetate (PVAC) base molecule is "saponified" to polyvinyl alcohol.
  • the PVAL can be introduced as finely ground granules, as an aqueous solution or as a dispersion.
  • the throughput in the extruder can be appreciably increased, the end product also having better foaming with good elasticity / flexibility.
  • plasticizers and / or lubricants such as e.g. Glycerol can be added.
