Problems solved by technology

However, the traditional UV-curable adhesive still has some defects in the specific application process. During the process, internal stress is likely to be generated, resulting in a significant drop in bond strength; in addition, there may be shadows in the bonded parts in some places, and ultraviolet light cannot pass through or can only partially pass through, resulting in these parts not being completely cured, corresponding to these The bonding strength of the parts is reduced and the corrosion resistance and aging resistance are reduced

Abstract

The invention belongs to the field of adhesives and particularly relates to an ultraviolet light curing adhesive for 3D printing powder and a preparation method of the ultraviolet light curing adhesive. The ultraviolet light curing adhesive for the 3D printing powder is characterized in that the adhesive is a resin adhesive, is used for rapid forming of the 3D printing powder, is quickly cured under ultraviolet light irradiation, is adhered onto powder particles to form a whole body, does not need post-treatment and comprises the following components in parts by weight: 30-50 parts of acrylate, 1-5 parts of a photo-initiator, 3-5 parts of a toughening agent, 5-15 parts of a filling agent, 1-3 parts of a coupling agent, 0.5-2 parts of a stabilizing agent and the balance of a diluting agent. The adhesive prepared by the preparation method provided by the invention is simple in use condition, green and environment-friendly, good in product performance, high in precision and high in adhering speed; selected resin has no thermal effect during curing, smaller contraction force is generated in the curing process, and the adhesive force is strong; raw materials are widely available, and the preparation method is simple and easy to implement, low in cost and beneficial to market popularization.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to an ultraviolet light curing adhesive for 3D printing powder and a preparation method thereof. Background technique [0002] 3D printing is hailed as another industrial revolution that subverts traditional manufacturing. Its molding process is: first design the required computer three-dimensional curved surface or solid model by software, and then layer it according to a certain thickness according to the process requirements, transform the original three-dimensional electronic model into two-dimensional plane information, and then convert the original three-dimensional electronic model into two-dimensional plane information The layered data is processed to a certain extent, the processing parameters are input, and the numerical control code is generated: under the control of the microcomputer, the numerical control system sequentially processes each thin layer in a plane proc...
