Problems solved by technology

[0003] However, the photocurable resin materials currently used in SLA and DLP generally have poor mechanical properties, brittle resin, poor toughness, low elongation at break, low impact resistance, free radical and cationic hybrid photocurable resin printing After a few months of storage, it is easy to crack when bent, and the free radical photocurable resin shrinks greatly, and its hardness and elongation at break are low.
Photocurable resin materials with poor mechanical properties cannot print ideal objects, and these shortcomings limit the pr

Example Embodiment

[0014] (1) Preparation of epoxy acrylic resin: Weigh a certain amount of epoxy resin, dissolve it in toluene solvent, stir to dilute the solution, pour it into a three-necked flask and place it in a 90°C oil bath to heat and stir to make it Fully dissolve; in addition, accurately measure a certain amount of acrylic acid and place it in a beaker, and add N,N-xylidine and hydroquinone to form an acrylic acid system. After fully stirring, drop the above acrylic acid system into the 90°C ring In the oxygen resin, react stably for 1 hour, then gradually increase the temperature to 95°C, and then react for 1 hour; after the reaction, the product is suction filtered and cooled to room temperature to obtain a light yellow transparent colloidal liquid, namely epoxy acrylic resin; The mass ratio of resin and acrylic acid is 2.5:1, the mass ratio of N,N-xylene amine and polymerization inhibitor hydroquinone is 1:3, and the mass ratio of N,N-xylidine to epoxy resin is 1 :12.

Abstract

The invention discloses an anti-static light-cured resin material for 3D (three-dimensional) printing, which comprises the following raw materials in parts by weight: 75 to 85 parts of epoxy acrylate resin, 1 to 5 parts of a reactive diluent, 5 to 15 parts of a composite anti-static agent, 1 to 5 parts of a photoinitiator, 1 to 3 parts of other auxiliary agents, 1 to 10 parts of graphene and 1 to 10 parts of multi-walled carbon nanotubes, wherein the weight ratio of the epoxy acrylate resin, the graphene and the multi-walled carbon nanotubes is 80:(2-5):(2-8); and the composite anti-static agent comprises stannic oxide, titanium oxide and poly(ether-ester) according to the weight ratio of (1-4):(3-5):(1-4). The composite anti-static agent, the graphene and the multi-walled carbon nanotubes are dispersed in the light-cured resin, so the prepared light-cured resin material is higher in break elongation rate and maximum bending strain than those of the common light-cured resin to a certain degree, a forming part printed by a 3D printer has higher mechanical properties and an excellent anti-static effect, an anti-static product produced by the forming part is suitable for special engineering, and the application range of 3D printing is further widened.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a photocurable resin material for antistatic 3D printing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is actually an emerging technology in the field of rapid prototyping. A technique for constructing objects in a manner. The basic principle is additive manufacturing, the technique of adding material layer by layer to generate a three-dimensional solid. At present, 3D printing technology is mainly used in product prototyping, mold manufacturing, art creation, jewelry making and other fields, replacing these traditional fine processing techniques. In addition, 3D printing technology is gradually applied in fields such as medicine, bioengineering, architecture, clothing, aviation, etc., opening up a broad space for innovation. [0003] However, the photocurable resin materials currently used in SLA and DLP generally ha...
