Algal residue containing 3D printing wire rod and preparing method thereof

Abstract

The invention discloses an algal residue containing 3D printing wire rod and a preparing method thereof. The 3D printing wire rod is prepared from 59-91 wt% of matrix resin, 8-40 wt% of algal residuesand 0.05-2 wt% of white oil. The preparing method includes the steps of firstly, conducting drying; secondly, weighing the materials; thirdly, conducting high-speed kneading; fourthly, conducting melting and granulating; fifthly, conducting melting and extruding; sixthly, conducting cooling and dragging; seventhly, conducting binding; eighthly, conducting printing through the FDM technology to form a specific structure. By introducing the residual biomass, the wire rod is rich in functionality group, can be combined with dye molecules or heavy metal ions and is low in price; the fine particleporous supporting framework is prepared through the efficient precise FDM technology. The wire rod as an adsorbing agent overcomes the defect that secondary contamination is caused when an adsorbingagent and a solution can hardly be separated after dyes are processed by polysaccharides in the forms of solution, powder, microspheres and gel; the wire rod has certain recycling performance, and thegreen circulation and efficient utilization of the material are realized.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a 3D printing wire material containing algae residue and a preparation method thereof. Background technique [0002] Water pollution caused by heavy metals and dyes has always been a serious environmental problem. Heavy metal ions and synthetic dyes are common toxic and carcinogenic substances. They are not easily biodegradable and accumulate in organisms through the food chain, leading to various diseases and disorders. Adsorption is the most commonly used method for this type of wastewater treatment in many researchers and engineering practices. Since the adsorbents used are mostly in the form of powder, this makes subsequent treatment difficult, causing serious secondary pollution, and contains dyes. Or the heavy metal adsorbent is highly toxic, and the energy consumption and cost input are too large if the conventional centrifugation method is used to collect. Most chem...
