preparation example Construction

[0043] figure 1 A schematic flow chart showing a method for preparing a three-dimensional pattern coating according to an embodiment of the present invention is shown. see figure 1 As shown, the preparation method may at least include the following steps S10 to S50.

[0044] Step S10: Perform pretreatment on the substrate.

[0045] The substrate can be a metal substrate, such as aluminum, copper, iron, etc., which is selected according to actual application requirements, and the present invention does not specifically limit it. The shape of the substrate can also be selected according to actual application requirements, for example, a ring shape, a flat plate shape, and the like. By pre-treating the substrate, the cleaning and / or protection of the substrate can be achieved, so as to prepare for the subsequent application of coatings.

[0046] Step S20: coating a first thickness of thermosetting acrylic resin-based primer on the substrate, the first thickness being in the r...

Embodiment 1

[0075] An iron substrate is used in this embodiment.

[0076] Step 1: Sanding. 180-mesh sandpaper and 600-mesh sandpaper were used for rough polishing and fine polishing of the iron substrate, respectively.

[0077] Step 2: Degrease. Degrease the iron substrate by immersing it in a general degreasing agent at 40°C for 20 minutes. The ingredients of the universal degreaser are as described above.

[0078] Step 3: Wash with water. Wash with pH7-8 water for 2 minutes at room temperature to remove residual degreasing agent.

[0079] Step 4: Rust removal. Use a rust remover with a full acidity of 6-10pt at room temperature for 15 minutes to remove the rust on the surface of the iron substrate. The ingredients of the rust remover are as mentioned above.

[0080] Step 5: Wash with water. Specifically, first wash with pH 5-6 water at room temperature for 2 minutes, and then wash with pH 6-7 water for 2 minutes at room temperature to remove residual rust remover.

[0081] Step...

Embodiment 2

[0096] The difference between this embodiment and Embodiment 1 is only:

[0097] The spraying thickness of the primer is 11 μm, and titanium dioxide is used as a colored filler in the primer. The spraying thickness of the topcoat is 11 μm, and the cracking agent in the topcoat is 9006-65-8 type cracking agent with a content of 0.5wt%. Finally, a three-dimensional pattern coating with white background color and uniform cracks is obtained. The three-dimensional pattern coating prepared in this embodiment has passed the 100-grid test, the paint film hardness test, the salt spray test, the alternating damp heat test and the cold and heat shock resistance test, and its adhesion, hardness, corrosion resistance, alternating resistance and resistance Both cold and heat shock properties are qualified.

Abstract

The invention provides a preparation method for a three-dimensional pattern coating, the three-dimensional pattern coating, a lamp accessory and a lamp. The preparation method comprises the followingsteps: carrying out pretreatment on a substrate; coating the substrate with a thermosetting acrylic resin-based primer with a first thickness, wherein the first thickness is in a range of 9-12 micrometers; drying the primer at a first specified temperature; coating the dried primer with thermosetting acrylic resin-based transparent finish paint with a second thickness which contains a cracking agent, wherein the second thickness is in a range of 10-13 micrometers; and drying the finish paint at a second specified temperature to obtain the three-dimensional pattern coating on the substrate. Thedifference of the shrinkage rates of the priming paint with specific thickness and the finishing paint with specific thickness is utilized, a cracking agent is used for assistance, so that the finishing paint is cracked to form the texture similar to ice patterns, and the three-dimensional pattern coating is obtained. The coating is unique in pattern and has a three-dimensional effect. In addition, the preparation method is simple in process and wide in application range.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a three-dimensional pattern coating, a three-dimensional pattern coating prepared according to the preparation method, a lamp fitting with a three-dimensional pattern coating and a lamp including the lamp fitting. Background technique [0002] In the prior art, surface treatment processes for hardware workpieces (such as metal frames) generally include painting, powder spraying, anodizing, electroplating, electrophoresis, water transfer printing, and the like. The water transfer printing process mainly includes sequential grinding (polishing), degreasing (or rust removal), washing, drying, priming, drying, water transfer printing, drying, topcoating, drying, testing, packaging and other processes. The water transfer printing process can be used to make various simulated patterns (such as wood grain, stone grain, etc.), but the process is complicated, and ...
