Abstract

The invention relates to 3D printing materials and discloses a 3D printing light-cured composition based on acrylic resins. The 3D printing light-cured composition comprises the following components in percentage by weight: 15-40% of aliphatic polyurethane acrylate, 20-25% of N-acryloyl morpholine, 20-25% of propyl oxynonylphenol acrylate, 15-25% of ethoxyethoxyethyl acrylate, 2-4% of an initiatorTPO, 0.6-1.5% of a KH570 silane coupling agent and 0.01-0.2% of a silane leveling agent. The composition disclosed by the invention is odorless, excellent in toughness, easy to demold and low in price.

Description

technical field [0001] The invention relates to ring 3D printing materials, in particular to a 3D printing material based on acrylic resin. Background technique [0002] 3D printing is a technology that has received widespread attention in recent years, and 3D printing materials are a vital part of 3D printing. Polymer materials, mainly light-cured polymer materials, are a large category of 3D printing materials. And UV acrylate is fully used, but there are the following problems: [0003] Polymer materials and their cured components usually have peculiar smell, which affects the health of users; in addition, the release problem that plagues the field of polymer processing also exists. From the perspective of 3D printing, at present, the weight of the product only accounts for half of the input materials, which is a huge waste, and the high market price of 3D printing materials leads to high prices of 3D printing products. In addition, existing materials have high hardnes...
