A kind of polishing fluid for improving the surface of ABS fused deposition molding and preparation method thereof

Abstract

The invention discloses a polishing solution for improving the surface of ABS fused deposition molding, which consists of the following components according to mass percentage: 30%-40% of polymethyl methacrylate, 60%-70% of the previous mixed solution, the above-mentioned components The sum of the mass percentages of the components is 100%. The invention also discloses a preparation method of the polishing liquid used for improving the surface of the ABS fused deposition molding, which is prepared by heating and mixing. The polishing liquid for improving the surface of ABS fused deposition molding can quickly form a film on the surface of the workpiece to be treated, and can fill the surface depressions to achieve smoothness while melting the surface protrusions of the workpiece, and has high bonding strength and no friction. poisonous, shortening the polishing cycle of the workpiece; the preparation method of the polishing liquid for improving the surface of ABS fused deposition molding is simple in operation, strong in practicability and high in preparation efficiency.

Description

technical field [0001] The invention belongs to the technical field of surface polishing liquid, relates to a polishing liquid for improving the surface of ABS fused deposition molding, and also relates to a preparation method of the polishing liquid for improving the surface of ABS fused deposition molding. Background technique [0002] Fused deposition modeling (FDM) is the inverse process of tomography, that is, parts are layered, printed layer by layer by melting filaments, and then superimposed together to form a three-dimensional object, thereby realizing the manufacture of arbitrary complex parts. Compared with traditional mold processing, this technology has greatly reduced cycle time, low investment, low cost, and can manufacture more complex structures, so it is widely used in various industries. However, due to the characteristics of layer-by-layer printing in the additive manufacturing process, the parts have a "step" shape, which makes the surface of the parts r...

Problems solved by technology

Among them, the principle of surface coating treatment is the same as nail art or wall painting. This method has weak adhesion and large size increase; organic solvent surface treatment currently uses acetone, ethyl acetate, methyl ethyl ketone, dimethylacetamide, xylene, After toluene, trichloroethylene, methyl ethyl ketone, methylene chloride, n-propyl bromide, and perchlorethylene are heated at high temperature or prepared with an aqueous solution, the steam or aqueous solution is directly dissolved on the surface of the plastic part, causing swelling and making it uniform. Grinding effect, its disadvantages are long fumigation and soaking time, and organic solvents are slightly toxic or toxic, volatile, easy to explode when heated too much, long reaction time, and have a great impact on the physical properties of the matrix material
