A kind of 3D prints glass material binding agent and application thereofTechnical field
The present invention relates to a kind of 3D printed material binding agent and application thereof, be specifically related to a kind of 3D and print glass material binding agent and application thereof.
Background technology
3D printing technique, also known as increasing material manufacturing technology, is a kind of emerging technology in rapid shaping field, and it is a kind of based on digital model file, uses powdery metal or plastics etc. can jointing material, is carried out the technology of constructed object by the mode successively printed.Along with development and the application of 3D printing technique, material becomes one of key factor of restriction 3D printing technique future trend, and to a certain extent, can the development of material decide 3D and print have and apply widely.At present, 3D printed material mainly comprises engineering plastics, photosensitive resin, rubber type of material, metallic substance and stupalith etc., in addition, the foodstuffs material such as coloured plaster material, artificial bone meal, cell biological raw material, glass material and granulated sugar also prints field at 3D and obtains application.
The exploitation of numerous 3D printed material and use, not only expanded the range of application of 3D printing technique, also impels the development and production of more subsidiary material simultaneously, as: binding agent.Binding agent as one of subsidiary material most important in 3D printing technique, need to have that cohesive strength is high, curing speed fast, environmental protection, the requirement such as easy to use.Print along with increasing novel material is used for 3D, the performance that novel material possesses and feature cause current binding agent major part can not be used for the 3D printing shaping of novel material, and along with the universal and application in daily life of 3D printing technique, condition of molding and environmental issue become new restraining factors, thus invent the binding agent that a kind of working conditions is simple, health environment-friendly, cohesive strength are high, curing speed is fast and are widely used in the significant of life to 3D printing.
Glass material is a kind of type material printed for 3D that current laboratory is using, and this material is with a wide range of applications, and can be widely used in daily life, have wide market by means of 3D printing technique.Current glass material 3D prints and mostly is indirect forming, glass powder or glass fibre are carried out mixing passing through Deformation In The Fdm Process with other plastic materials, the product prepared has some performance of glass, but be not pure glass material, erosion resistance and hardness etc. all differ comparatively large with pure glasswork, be unfavorable for applying widely in life.China Patent Publication No. is that CN103935036A discloses a kind of powder 3D Method of printing using photosensitive sol adhesive, photosensitive sol adhesive is have employed in the method, molding bonded can be carried out fast to powdered material, but be unsuitable for pure glass material molding bonded, therefore, invent a kind of binding agent pure glass material molding bonded to be applied to 3D printing shaping technology and to obtain product, good product performance, precision is high, shaping speed is fast, by the application that promotes 3D printing shaping technology greatly on glass material and the popularization of 3D printing shaping in life, there are wide market outlook.
Summary of the invention
The present invention is directed to shortcoming that current pure glass material can not directly apply to 3D printing technique and obtained product to propose a kind of 3D and print glass material binding agent and application thereof.
A kind of 3D of the present invention prints glass material binding agent, it is characterized in that for oily, print the rapid shaping of glass material for 3D, fast setting under UV-irradiation, glass powder is carried out molding bonded and combine formation entirety simultaneously, its each component is counted by weight:
