Problems solved by technology

However, these adhesives are prone to warping and peeling during printing because they do not provide sufficient bond strength, but if too much standard adhesive is used, the printed product may stick to the printing platform and cannot be removed

Abstract

The invention discloses a 3D printing adhesive and a preparation method thereof. The 3D printing adhesive comprises the following components in parts by weight: 20-25 parts of polystyrene, 10-15 parts of butyl acetate, 45-50 parts of ethyl acetate, 35-40 parts of dichloromethane, 5-8 parts of benzotriazole, 3-5 parts of polypropylene glycol, 6-9 parts of sodium carboxymethylcellulose, 6-8 parts of alpha-cassava starch and 4-6 parts of 4,4'-bi(alpha,alpha-dimethyl benzyl) diphenylamine. A 3D printing platform can be coated with the adhesive disclosed by the invention, the adhesive can be solidly adhered to the printing platform when the printing platform is heated, and thus warping and peeling can be prevented. By adopting the 3D printing adhesive, not only is the adhesive force improved, but also a product can be taken conveniently, a 3D printed product can be relatively easily detached after the 3D printed product and the printing platform are cooled, and the printing platform can be clean and smooth.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a 3D printing adhesive and a preparation method thereof. Background technique [0002] In recent years, 3D printing technology, as an emerging technology in the field of rapid prototyping, has developed very rapidly and has been applied in aerospace, biomedicine, national defense and military industry, engineering education, new product development and other fields. 3D printing technology uses 3D CAD models to quickly and accurately manufacture complex structural parts on one device, thereby realizing "free manufacturing", solving the limitations of difficult or impossible processing of traditional processes, and greatly shortening the processing cycle. [0003] During 3D printing, adhesives need to be sprayed on the printing platform for bonding materials. Currently, standard adhesives like Elmer's glue, glue sticks or ABS adhesives are mainly used. However, these adhesives are prone ...
