Embodiment 1

[0035] 1. Collect 100g of gutter oil obtained from the simple processing of swill from fast food restaurants. Get 62g of hydrogen peroxide (30% hydrogen peroxide aqueous solution), 16g of glacial acetic acid, 0.4g of concentrated sulfuric acid, and 0.4g of urea, mix them, and react in the dark at 40°C for 12 hours in the dark to obtain an epoxidation reagent. Then, in a glass reactor with a stirrer, add the obtained waste oil, heat to 40°C, slowly add the epoxidation reagent dropwise under stirring, after the dropwise addition, raise the temperature to 70°C, heat and stir for 3 hours, then cool and stand , separate the oil layer, wash 3 times with 5% sodium bicarbonate solution, then wash 6 times with 60°C deionized water, collect the oil layer, and vacuum rotary evaporation at 70°C for 1 hour until it becomes clear and anhydrous A pale yellow, liquid epoxy gutter oil product is obtained.

Abstract

The invention discloses a wood-color-like 3D printing wire material based on illegal cooking oil, and preparation and 3D printing methods of the wire material. The wire material is a yellow woody wire. The preparation method of the wire material comprises the steps of epoxidized illegal cooking oil to obtain epoxidized illegal cooking oil, and then performing a ring-opening esterification reactionon the epoxidized illegal cooking oil and acrylic acid to obtain an epoxidized illegal cooking oil acrylate-acrylic acid prepolymer, then adding an initiator, performing heating solidification to obtain an epoxidized illegal cooking oil acrylate-acrylic acid solidified product, and finally blending the solidified product with polylactic acid for wire drawing, so as to obtain the wood-color-like 3D printing wire material based on the illegal cooking oil. The wire material can be printed by a commercial FDM 3D printer, and the printed product has a yellow wood-like appearance, and has low cost,good toughness and good application prospects.

Description

technical field [0001] The invention relates to a wood-like 3D printing wire material based on waste oil, its preparation and 3D printing method, and relates to the fields of waste oil recycling, 3D printing and polymer materials. Background technique [0002] Waste oil is a general term for all kinds of low-quality oil in people's daily life, including the daily operation of catering units, the daily diet of residents, and the waste oil produced in the production process of food, oil and other processing enterprises. These waste oils not only have low nutritional value, but also contain a variety of ingredients harmful to the human body, so they cannot be used for food. If waste oil is not recycled, it will not only waste precious natural resources, but also cause secondary pollution to natural environments such as water bodies. A large amount of waste oil may also flow into the table after being processed and refined by illegal elements, posing a huge threat to the health...
