Embodiment 1

[0012] Add the auxiliary agent solution composed of 1 g of emulsifier potassium oleate soap, 5 g of mercaptan, and 0.5 g of potassium persulfate together with 100 g of butadiene into the polymerization kettle, the reaction temperature is 90 degrees Celsius, and the reaction time is 16 hours. Cool to obtain polybutadiene latex. The conversion of butadiene was 80%.

[0013] Add 10 g of acrylonitrile, 60 g of styrene monomer and 5 g of the polybutadiene latex obtained above into the reactor, use cumene peroxide as the initiator, the reaction temperature is 90 degrees Celsius, the reaction time is 5 hours, and the reaction ends Finally, coagulation is carried out, the coagulation agent is dilute sulfuric acid or alum, the coagulation temperature is 90 degrees Celsius, and fine particles are obtained by coagulation. After washing, dry to obtain ABS grafted powder. The moisture content of the dried ABS grafted powder is less than 0.5%. The conversion of monomer was 88%.

Abstract

The invention discloses a preparation method of toughened 3D (three-dimensional) printing consumables. According to the method, additives are added to ABS (acrylonitrile butadiene styrene) grafting powder and are mixed with SAN (styrene-acrylonitrile resin) particles, after the mixture is uniformly mixed, extrusion and palletizing are carried out, and products are obtained; the three raw materials have the proportion in parts by weight: 40 to 70 parts of ABS grafting powder, 5 to 10 parts of additives and 30 to 50 parts of SAN particles; the additives are mixtures of polyphenyl ether, polycarbonate and modified polyacrylic ester. The preparation method provided by the invention has the advantages that the reaction conditions are mild, the operation is simple, and the 3D printing consumables prepared by the method have high impact resistant intensity and good toughness.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to a preparation method of toughened 3D printing consumables. Background technique [0002] 3D printing is a process of building three-dimensional objects through computer modeling and control, thermal dissolution reconstruction or laser molding technology. Because the process is similar to traditional printing, it is vividly called "3D printing". The so-called 3D printer works basically the same as ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with different "printing materials" such as metal, ceramics, plastics, and sand. Real raw materials, after the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer can be turned into a real object.
