Problems solved by technology

For example, relevant research has proved that skeletal organs that meet the requirements can be made through 3D printing, but the problem of printing materials has not been completely solved, so that it cannot be used for organ transplantation
At the same time, every type of 3D printing equipment in foreign countries has matching printing materials, which lack versatility and are relatively expensive, especially because the physical finished product has low flexibility and mechanical properties, making it difficult to be widely used.

Abstract

The invention discloses an organic-inorganic hybrid 3D printing material and a preparation method thereof. The 3D printing material is prepared from 40-80 parts of a hard monomer, 10-25 parts of a soft monomer, 5-10 parts of a carboxyl group-containing monomer, 10-20 parts of quaternary ammonium salt interlayer modified montmorillonite powder, 0.2-1.5 parts of an initiator and a solvent. The organic-inorganic hybrid montmorillonite/polyacrylate is prepared through free radical polymerization of an acrylate monomer in a montmorillonite interlayer by using an in situ polymerization technology; and the organic-inorganic hybrid montmorillonite/polyacrylate can be used as a 3D printing material to make entire products with excellent mechanical performances and flexibility in order to basically meet present industrial application requirements. The material disclosed in the invention has the advantages of simple preparation process and low production cost.

Description

technical field [0001] The invention relates to a 3D printing material and a preparation method thereof, in particular to an organic-inorganic hybrid 3D printing material and a preparation method thereof. Background technique [0002] Manufacturing is the main material basis for the development of human society, and it directly reflects the level of science, technology and economic strength of a country or region.
