Embodiment 1 Embodiment 8

[0060] Embodiment 1 to Embodiment 8 Preparation of UV-cured superhydrophobic materials for 3D printing

[0061] First, mix the oligomer and the diluent in a certain proportion at room temperature, and stir at a speed of 1000-3000r / min for 5-10min to make it evenly mixed. After the system is evenly mixed, add the initiator, part of the defoamer and Stir the remaining additives at the same stirring speed until the initiator is completely dissolved, then add the remaining initiator, stir at a low speed until it is uniform and free of bubbles, store it in the dark for a period of time, and dry it in vacuum at 40°C to constant weight to obtain a UV light for 3D printing. Cured superhydrophobic material, wherein, the ratio of each substance in the preparation process is shown in Table 1.

Abstract

The invention provides an ultraviolet curing super-hydrophobic material composition used for 3D printing and a preparation method thereof. The composition comprises 30-60 parts of an oligomer component, 10-30 parts of a reactive diluent and 1-5 parts of a photoinitiator. The invention also provides a preparation method of an ultraviolet curing super-hydrophobic material used for 3D printing. The method at least comprises the following steps: mixing and stirring 30-60 parts by weight of an oligomer and 10-30 parts by weight of a diluent, so that a first mixed liquor is obtained; and adding 1-5parts by part of the photoinitiator into the first mixed liquor, stirring until the photoinitiator is dissolved, and keeping in a dark place, so that a second mixed liquor is obtained. The prepared ultraviolet curing super-hydrophobic material used for 3D printing has stronger hydrophobicity, foul resistance of the material is improved, and hardness, tensile strength, viscosity, volume shrinkage and other properties of the material are not reduced. Besides, the ultraviolet curing super-hydrophobic material composition used for 3D printing is simple in preparation technology, and industrialization can be easily realized.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to an ultraviolet light curing material for 3D printing and a preparation method thereof, in particular to an ultraviolet light curing superhydrophobic material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to accumulate metal powder, ceramic powder, plastic, cell tissue and other special materials layer by layer Bonding and final overlay molding to create a solid product. [0003] Unlike the traditional manufacturing industry, which shapes and cuts raw materials through mechanical processing methods such as moulds, turning and milling to finally produce finished products, 3D printing transforms a three-dimensional entity into several two-dimensional pl...
