Description

Coloring technology for CNC (computer numerical control) machining of PMMA (polymethyl methacrylate) transparent part

Technical Field

The invention relates to the technical field of PMMA material coloring, in particular to a coloring technology for CNC machining of a PMMA transparent part.

Background

Acrylic, also called PMMA or organic glass, has a chemical name of polymethyl methacrylate, is an important plastic polymer material which is developed earlier, has better transparency, chemical stability and weather resistance, is easy to dye, process and beautiful in appearance, and is widely applied to the building industry.

The PMMA processing raw materials on the current market are generally colorless and transparent, but the color of the product is mostly red or smoked gray due to the requirement, the current process is generally realized by spraying colored transparent paint, the integral appearance texture is not high, the defective rate of coloring is high, and the factors such as optical disqualification and the like are easy to appear.

Disclosure of Invention

Aiming at the defects in the background technology, the invention provides a coloring technology for CNC machining of PMMA transparent parts.

The invention adopts the following technical scheme for solving the phenomenon, and the coloring technology for CNC machining of PMMA transparent parts comprises the following steps:

s1, dye preparation: firstly, taking out the water-based dye, then adding the water-based dye into clear water according to a certain proportion, mixing and stirring, and placing for later use;

s2, heating: heating and melting the mixture after stirring the mixture to be completely mixed, and then keeping the mixture in a constant temperature state;

s3, staining: placing a product to be dyed in the dye, sealing the placed container, judging whether the product is dyed successfully by a worker according to the color depth to be dyed, and properly adjusting the time in the dyeing process;

s4, drying: and taking out the dyed product, drying the product, and then putting the dried product into an oven for drying treatment, so that the color is uniformly permeated into the PMMA material.

In a further preferred embodiment of the present invention, in step S1, the aqueous dye is first taken out, then the aqueous dye is added into clear water according to a certain proportion, mixed and stirred, and simultaneously the aqueous dye and the clear water are added according to a proportion of 10:3, and stirred for 5min to 8min by using a stirrer.

As a further preferable mode of the present invention, in step S2, after stirring to complete mixing, it is heated to melt, and it is necessary to keep the heating temperature between 65-70 degrees, and then to keep it in a constant temperature state, with an error of not more than 3 degrees.

As a further preferable mode of the present invention, in step S3, the product to be dyed is placed inside the dye, the placed container is sealed, the product is immersed inside the dye and left standing for 30min, and the worker determines whether the product is successfully dyed according to the shade of the color to be dyed, and the time can be properly adjusted during the dyeing process.

As a further preferable mode of the present invention, in step S4, the dyed product is taken out, wiped dry, and then placed in an oven for drying treatment, wherein the drying time is controlled between 3h and 3.5h, so that the color is uniformly permeated into the PMMA material, and the permeation depth can reach 0.2 MM.

According to the invention, the traditional acrylic coloring process is changed, and the coloring processing is carried out by adopting a dyeing method, so that the color penetration depth of the processed acrylic can reach 0.2MM, the appearance and the optical performance are not damaged, and the processing and manufacturing precision and the success rate of the product are greatly improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a technical scheme that: a coloring technology for CNC machining of PMMA transparent parts,

the coloring method comprises the following steps:

In step S1, the aqueous dye is taken out firstly, then the aqueous dye is added into clear water according to a certain proportion for mixing and stirring, meanwhile, the proportion of the aqueous dye and the clear water is 10:3, and the mixture is stirred by a stirrer for 5min to 8 min.

In step S2, heating to melt the mixture after stirring to complete mixing, and keeping the heating temperature between 65-70 degrees, and then keeping the temperature constant, wherein the error is not more than 3 degrees.

In step S3, the product to be dyed is placed inside the dye, the container is sealed, the product is immersed inside the dye and left standing for 30min, and the worker determines whether the product is dyed successfully according to the color shade to be dyed, and the time can be adjusted properly during the dyeing process.

In step S4, the dyed product is taken out, wiped dry, and then placed in an oven for drying, and the drying time is controlled between 3h and 3.5h, so that the color is uniformly permeated into the PMMA material, and the permeation depth can reach 0.2 MM.

In conclusion, the invention changes the traditional acrylic coloring process and adopts the dyeing method for coloring, so that the color penetration depth of the processed acrylic can reach 0.2MM, the appearance and the optical performance are not damaged, the processing and manufacturing precision and the success rate of the product are greatly improved, meanwhile, the optical permeability is not influenced, and the practicability is strong in application.
