Description
Technical Field
The invention relates to the field of coloring agents, in particular to a coloring solution for a nylon product and a surface coloring treatment method for the nylon product.
Background
The 3D printing technology is a technology for manufacturing a rapid forming part by utilizing the principles of layer-by-layer superposition and accumulation forming. Because of the additive manufacturing, the design of the structure can be designed almost freely without being influenced by the processing mode. Many designers have designed products with a wide variety of 3D structures. On the other hand, with the popularization and the promotion of 3D printing technology, the application of 3D printing supplies is more and more extensive. Nylon is one of 3D printing consumables, has a great deal of advantages such as intensity height, chemical stability are good, wear resistance is good, is the preferred material of industrial grade 3D printing more. However, due to the limitation of the printing principle, the nylon part printed by 3D has more surface pores and poorer roughness; in addition, due to the limitation of the forming process and the forming speed, the model printed by the 3d printer is difficult to overcome the laminated texture formed in the Z-axis direction, and the effects of smooth surface, uniform color and difficult fading after coloring treatment of the product are difficult to achieve, so that the appearance quality and the application of the product are influenced. The existing coloring treatment method usually needs a complicated process and harsh treatment conditions, and is high in time cost and economic cost, so that the popularization and the use of 3D printing nylon parts are not facilitated.
Disclosure of Invention
The invention aims to solve the technical problem of providing a dyeing solution for nylon workpieces and a surface coloring treatment method for the nylon workpieces, wherein the nylon workpieces colored by the dyeing solution have smooth surfaces, uniform colors, good light resistance and difficult fading.
The technical scheme adopted by the invention is as follows:
the invention provides a dyeing liquid for nylon workpieces, which comprises 6.25-12 parts by mass of n-butyl alcohol, 6.25-12 parts by mass of butyl acetate, 26-37.5 parts by mass of acrylate, 10-25 parts by mass of organic carboxylic acid, 15-30 parts by mass of dye, 0.5-1 part by mass of an auxiliary agent and a pH regulator, wherein the pH regulator is used for regulating the pH of the dyeing liquid to 4-6.
Preferably, the pH adjusting agent is a buffer.
Preferably, the organic carboxylic acid is a saturated monocarboxylic acid having C1-C3. The larger the number of carbon atoms in the saturated monocarboxylic acid, the less acidic the saturated monocarboxylic acid is, as compared with the macromolecular organic carboxylic acid, the more unfavorable the experiment under acidic conditions of the present invention is, and therefore, the small molecular organic carboxylic acid, i.e., the saturated monocarboxylic acid of C1 to C3 is preferable.
Still further preferably, the organic carboxylic acid includes any one of formic acid, acetic acid and n-propionic acid.
Preferably, the acrylate includes any one of modified epoxy acrylate, polyethylene glycol (400) diacrylate, ethoxylated pentaerythritol tetraacrylate, ethoxylated trimethylolpropane triacrylate, 1,6 hexanediol diacrylate, tripropylene glycol diacrylate, and dipropylene glycol diacrylate.
The modified epoxy acrylate refers to chemically modified epoxy acrylate, and the chemical modification is to prepare modified epoxy acrylate with different performances by reacting epoxy groups or hydroxyl (-OH) groups after ring opening in epoxy resin with other modified substances so as to improve the performances of the epoxy acrylate. For example, a part of epoxy groups in the epoxy resin firstly carry out ring-opening reaction with alcohol, carboxylic acid or amine and then are esterified by acrylic acid to prepare modified epoxy acrylate, namely organic compounds of hydroxyl (-OH), carboxyl (-COOH) or amino (-NH2) groups are grafted in the epoxy resin, so that the performance of the epoxy acrylate can be effectively improved.
The modified epoxy acrylate selected by the invention comprises but is not limited to carboxylic acid modified epoxy acrylate (such as succinic acid epoxy acrylate, sebacic acid epoxy acrylate, adipic acid epoxy acrylate or suberic acid epoxy acrylate and the like), alcohol modified epoxy acrylate (such as polyethylene glycol, polybutadiene and triethylene glycol which are obtained by modifying epoxy resin firstly and then acrylating) and amine modified epoxy acrylate (such as diamine which is obtained by modifying epoxy resin firstly and then acrylating), and modified epoxy acrylate prepared by other modification methods which can effectively improve viscosity, glossiness, flexibility, pigment wetting dispersibility and adhesive force of epoxy acrylate. Preferably, the auxiliary agent comprises at least one of a leveling agent, a fixing agent and a dispersing agent.
Preferably, the dye includes any one of an acid dye, a reactive dye, an azo dye, a disperse dye, and a metal complex dye. Further preferably having a sulfonic acid group (-SO)3H) Or a water-soluble group molecular structure such as a carboxyl group (-COOH) because of a sulfonic acid group (-SO)3H) Or water-soluble group molecules such as carboxyl (-COOH) and the like are arranged in a linear type, and the aromatic ring structure is positioned on the same plane, so that the dye has higher affinity to the nylon product, the dye is adsorbed to the surface by the nylon product in the solution and continuously diffuses to the amorphous area of the nylon product to form hydrogen bonds and van der Waals force with nylon macromolecules, and the color fastness of the nylon product is further improved.
The invention also provides a surface coloring treatment method of the nylon product, which comprises the following steps:
(1) preparing the dyeing liquid for the nylon workpiece;
(2) and (2) putting a nylon workpiece into the dyeing liquid prepared in the step (1), and heating for dyeing.
Preferably, step (1) is: mixing 6.25-12 parts by mass of n-butyl alcohol, 6.25-12 parts by mass of butyl acetate, 26-37.5 parts by mass of acrylate, 10-25 parts by mass of organic carboxylic acid, 15-30 parts by mass of dye and 0.5-1 part by mass of auxiliary agent, adding glacial acetic acid to adjust the pH value to 4-6, adding 0.1-0.5 part by mass of sodium acetate, and uniformly mixing.
Preferably, the heating temperature in the step (2) is 96-120 ℃, and the heating time is 30-120 min.
Furthermore, the heating rate in the step (2) is 1-3 ℃/min. Too fast a temperature rise rate easily leads to too fast dye-uptake rate and uneven dyeing.
Preferably, step (2) further comprises a step of pretreating the nylon part before the nylon part is put into the container.
Further, the pretreatment is a polishing treatment.
Preferably, the dyeing in step (2) by heating further comprises a drying step. Further preferably, the drying is any one of natural drying, drying with a blower and drying in a drying oven.
Preferably, the nylon piece is a 3D printing nylon piece.
The invention has the beneficial effects that:
the invention provides a dyeing liquid for nylon products, wherein n-butyl alcohol (boiling point 117.8 ℃) and ethyl acetate (boiling point 126.2 ℃) are mixed to form butanol-butyl acetate azeotrope, the azeotropic point is 117.2 ℃, the melting point of nylon (taking nylon 12 as an example) is 170-180 ℃, and the butanol-butyl acetate azeotrope is adopted to enable the whole coloring experiment to be carried out in a lower temperature environment, so that the coloring treatment is ensured to have less influence on the shrinkage deformation of the nylon products. The method is characterized in that the key part of the method is the proportion of acrylic ester in n-butyl alcohol, butyl acetate and acrylic ester, the proportion of the acrylic ester in the three is always kept at 52-75%, experiments prove that the nylon product with smooth surface, uniform color and good light resistance can be obtained within the proportion range of the acrylic ester, the proportion of the acrylic ester is too high, a layer of grease is not easy to dry after the nylon product is dyed, and the impregnation effect of impregnation liquid formed when the proportion of the acrylic ester is too low is weak, so that the surface of the nylon product is dull and easy to fade.
