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

Abstract

The invention discloses a polishing solution used for improving ABS fused deposition moulded surfaces. 100% of the polishing solution is composed of, by mass, 30 to 40% of polymethyl methacrylate, and 60 to 70% of an early stage mixed solution. The invention also discloses a preparation method of the polishing solution used for improving ABS fused deposition moulded surfaces. The polishing solution is prepared through heating mixing, is capable of realizing rapid film forming on surfaces of workpieces to be processed, and filling surface recesses when molten workpiece surface projection is caused to smoothen the surface, is high in binding strength, is nontoxic, and is capable of shortening workpiece polishing period. The preparation method is simple in operation, high in implementation performance, 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...
