[0031] as the picture shows:

[0032] The preparation method of the environmentally friendly biomass material includes the following steps in parts by weight:

[0033] (1) Preliminary treatment of base material:

[0034] Waste paper fiber: After soaking and degumming the waste corrugated cardboard, it will be pulped by a hydraulic pulper until the mass proportion of flocculent components in the slurry is not more than 30%, and the average size of fiber flocs is not more than 5.0mm ; Then filter the slurry to a moisture content of 70~90% for use;

[0035] (2) Material mixing: Take 60 parts of waste paper fiber, 20 parts of corn starch, 15 parts of plasticizer, 2.5 parts of silane coupling agent, and 2.5 parts of lubricant from the base material prepared in step (1) and fully mix and stir at room temperature 20min, the stirring speed is 20r / min; then heat in a water bath while stirring continuously;

[0036] The plasticizer is a mixture of urea and glycerin; wherein th...

Abstract

The invention relates to a process method for continuously producing an environment-friendly biomass material by using an extruding method, and belongs to degradable environment-friendly biomass materials and the related technical field thereof. The environment-friendly biomass material is prepared by taking biomass fibers as main materials and starch as an auxiliary material; the materials are sufficiently agitated and mixed, and then are heated by a water bath; a semi-fluid state of the biomass fiber raw material is realized under a flow aiding effect after starch pasting; then the materials are continuously extruded by a screw-rod extruder and then is molded by a mould with the shape which is the same as that of an opening mould, so as to realize continuous production of the biomass materials; after being extruded, the materials are processed by processes of drying, compressing or foaming to prepare materials and products with different densities, sizes and mechanical properties. By virtue of adopting the process method provided by the invention, a continuous automatic production process of the biomass materials can be finished and the process method can be used as a former procedure for the biomass materials or the products and can also be used as a final procedure. Therefore, the cost can be saved and the production efficiency is improved.

Description

technical field [0001] The invention relates to a process method for continuously producing environmentally friendly biomass materials and products by extrusion, in particular to a new type of green environmental protection biomaterials such as paper angle protectors, paper channel steel and cardboard strips, which are continuously produced by extrusion of waste paper fiber raw materials. The invention relates to a process method for a material profile, which belongs to the field of degradable and environment-friendly biomass materials and related technologies. Background technique [0002] With the decrease of natural resources, the deterioration of the environment, and the increasing awareness of environmental protection, the utilization of biomass fiber materials with a wide range of sources, green environmental protection, and recyclability has attracted more and more attention. It is estimated that plants on the earth can produce 200 billion tons of cellulose, 150 billi...
