Abstract

The invention discloses a biomass base light door profile preparation method which includes the steps: mixing a first part of lignin granular materials and PVC (polyvinyl chloride) resin with first auxiliaries and enabling mixture to enter a twin-screw extruder for thermoplastic extrusion to obtain a biomass base thermoplastic hollow core door profile; liquefying a second part of lignin granular materials, polyethylene glycol 400 and glycerol under the condition of concentrated sulfuric acid serving as a catalyst into bio-polyol, mixing the bio-polyol with second auxiliaries into combined bio-polyol, and reacting the combined bio-polyol with isocyanate to generate a biomass base polyurethane hard foam material; pouring the biomass base polyurethane hard foam material into a hollow cavity of the biomass base thermoplastic hollow core door profile, and filling the whole hollow cavity with the biomass base polyurethane hard foam material to obtain a biomass base light door profile. The door profile is prepared from biomass materials, resource use efficiency is improved, the preparation method is environmentally friendly, and the prepared door profile has good use performance.

Description

technical field [0001] The invention relates to the field of door profile preparation, in particular to a method for preparing a biomass-based lightweight door profile. Background technique [0002] With the development of modern industry and the surge of world population, energy crisis, food crisis and environmental crisis are getting worse day by day. The current world economy is overly dependent on petroleum, coal and other fossil resources, and its non-renewability is causing the gradual depletion of such resources, and the price is rising steadily. The burning of such resources produces a large amount of carbon dioxide, sulfur dioxide and other gases and suspended particles, which has caused climate change. The environment is deteriorating day by day. Finding renewable clean energy to replace them has become the focus of scientific research departments in various countries. Among them, biomass energy has become the most potential energy source because of its advantage...
