Reinforcing flexibilizer used for 3D printing of ABS, ABS composite material, production method of ABS composite material

Abstract

The invention belongs to the field of polymer materials for 3D printing, and concretely relates to a reinforcing flexibilizer used for 3D printing of ABS, an ABS composite material, a production method of the ABS composite material. The reinforcing flexibilizer is prepared through fully mixing, by weight, 15-30 parts of carbon nano-powder, 4-8 parts of glass fibers and 7-12 parts of SBS resin powder; and the ABS composite material is prepared from, by weight, 40-60 parts of ABS resin powder, 15-20 parts of PLA resin powder, 10-20 parts of the reinforcing flexibilizer, 0.2-0.7 parts of an antioxidant and 5-10 parts of a dispersing agent. The reinforcing flexibilizer can be used to be combined with ABS resin in order to greatly improve the toughness and the strength of an ABS material; the ABS composite material has obviously enhanced strength and toughness, and the shrinkage rate of the melt of the ABS composite material is reduced to 0.5% or below in the cooling process; and components of the ABS composite material contain PLA resin, so the ABS composite material has reduced irritating smell when used in 3D printing.

Description

technical field [0001] The invention belongs to the field of polymer materials for 3D printing, and in particular relates to a reinforcing and toughening agent for 3D printing ABS, an ABS composite material and a production method thereof. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing technology is generally used in the fields of mold manufacturing and industrial design, especially in the manufacture of samples before production. With the development of technology, it is gradually used in the direct manufacture of some products. In the prior art, 3D printing commonly used ABS materials of plastic materials adopts the manufacturing method of "layer-by-layer superimposition, inter-layer bonding", but limited by the strength and bonding performance of the material itself...

AI Technical Summary

Problems solved by technology

However, with the passage of time, people's requirements for 3D printing quality have improved, and some problems of ABS materials have gradually emerged. The most important ones are the lack of toughness and strength of ABS and the warping phenomenon caused by large shrinkage during the cooling process.
