Problems solved by technology

In the prior art, lignin components can only exist in the final prepared polyurethane in the form of fillers. Therefore, on the one hand, the purpose of replacing petroleum-based polyols with lignin components cannot be achieved, and on the other hand, lignin components cannot be present in polyurethane. Plays the role of macromolecular multi-functionality cross-linking core, resulting in poor binding performance of lignin components and polyurethane

Abstract

The invention discloses a preparation method of a biomass based lightweight window profile, wherein the preparation method comprises the steps: preparation of a hollow-core biomass based thermoplasticwindow profile, preparation of a biomass based polyurethane rigid foam material and preparation of the biomass based lightweight window profile. According to the method provided by the invention, with biomass as a raw material, a lignin-containing slag material obtained after a biomass raw material is subjected to enzymolysis, fermentation and separation is used as a raw material for production of a thermoplastic material, and the hollow-core biomass based thermoplastic window profile is prepared through mixing and thermoplastic extrusion; a combined biological polyol finished product and isocyanate are mixed at high speed in proportion to obtain the biomass based polyurethane rigid foam material through a foaming machine, the hollow-core biomass based thermoplastic window profile inner space is poured with the biomass based polyurethane rigid foam material through the foaming machine, and the solid-core lightweight window profile is formed. The prepared window profile has relativelyhigh tensile strength and has the characteristic of no water absorption.

Description

Technical field [0001] The invention relates to the field of building decoration industry, in particular to a method for preparing a biomass-based lightweight window profile. Background technique [0002] With the development of modern industry and the rapid increase of the world's population, the energy crisis, food crisis, and environmental crisis have become increasingly intensified. The current world economy is overly dependent on fossil resources such as oil and coal. The non-renewability of these resources is leading to the gradual exhaustion of such resources, and the prices are rising steadily. The burning of such resources produces a large amount of carbon dioxide, sulfur dioxide and other gases and suspended particulate matter, which has caused the climate. The environment is deteriorating day by day. Looking for renewable clean energy to replace them has become the focus of scientific research departments in various countries. Among them, biomass energy has become th...
