Problems solved by technology

[0004] At present, the light-curing 3D printing photosensitive resins on the market generally have a temperature resistance of less than 100°C; and their flame retardancy is poor. Although the resins mentioned in the relevant patents have certain temperature resistance and flame retardancy, the effect is not ideal.

Abstract

The invention discloses high-temperature-resistant halogen-free flame-retardant 3D printing photosensitive resin and a preparation method thereof. The high-temperature-resistant halogen-free flame-retardant 3D printing photosensitive resin comprises the following components in percentage by mass: a phosphate modified polyurethane acrylate oligomer, tri (2-ethoxyl) isocyanuric acid triacrylate; tricyclodecane dimethyl alcohol diacrylate; acryloyl morpholine; a flame retardant; a photoinitiator; a defoaming agent; a wetting leveling agent; an anti-settling agent; a polymerization inhibitor; and a UV absorber. The photosensitive resin has the beneficial effects that the temperature resistance and flame retardance of the photosensitive resin are greatly improved under the condition of ensuring printing forming.

Description

technical field [0001] The invention relates to 3D printing material technology, in particular to a high-temperature-resistant halogen-free flame-retardant 3D printing material and a production method thereof. Background technique [0002] 3D printing technology, also known as three-dimensional printing technology, is a technology that uses digital model files as the basis to construct objects by layer-by-layer printing. It can directly generate parts of any shape from computer graphics data without machining or any molds, thereby greatly shortening the product development cycle, improving productivity and reducing production costs [0003] Photosensitive resin material is a special resin with many advantages, generally composed of photosensitive prepolymer, reactive diluent and photosensitizer. Photosensitive resin materials can produce active fragments under the action of ultraviolet light, initiate polymerization and crosslinking reactions, and achieve curing in an insta...
