Problems solved by technology

However, in the bathroom industry, water transfer printing technology has not yet been promoted.
There are many types of base materials in the bathroom industry, and the application scenarios are mostly environments with high humidity, high temperature, and frequent use of detergents. Water transfer printing products often have defects such as coating blistering, peeling, and discoloration during use, which directly affect the product. Life expectancy and consumer experience, due to the reliability problems of the current water transfer printing technology in the bathroom industry, this technology has not been popularized in bathroom products

Embodiment 1

[0037] The water coating process is used to make wood grain on the aluminum alloy pendant shelf. refer to figure 1, pre-treat the aluminum alloy storage board (1000 mesh sandpaper grinding-water washing-degreasing-water washing), then put it in an oven at 70°C, and dry it for 30 minutes; then spray white epoxy-polyurethane medium paint, and spray the good medium paint Put the storage board in the oven at 155°C and bake for 20 minutes; then spray the amber yellow acrylic-polyurethane primer and put it in the oven for 25 minutes at 30°C. After the baking is completed, take out the storage board to prepare for the water transfer step; Set the water temperature of the sink to 30°C, then spread the water transfer film on the water surface with a water temperature of 30°C, wait for 1 minute, then spray the activator, and press the storage board into the water within 10 seconds after spraying the activator to transfer the water The film is transferred to the surface of the storage b...

Embodiment 2

[0039] The water coating process is used to make marble patterns on the faucet valve body made of copper alloy. refer to figure 1 , pre-treat the copper alloy valve body (water washing-degreasing-water washing), then put it in an oven at 70°C, and dry it for 30 minutes; then spray white epoxy-polyurethane medium paint, and put the sprayed medium paint on the storage board Oven at 155°C, bake for 20 minutes; then spray white acrylic-polyurethane primer, and put in the oven to bake at 70°C for 5 minutes. After the baking is completed, take out the valve body to prepare for the water transfer step; set the water temperature of the constant temperature water tank to 40°C , and then spread the marble pattern water transfer film on the water surface with a water temperature of 40°C, wait for 30s, spray the activator, press the valve body into the water within 10s after spraying the activator, and transfer the water transfer film to On the surface of the valve body, after the transf...

Embodiment 3

[0041] The water coating process is used to make wood grain on the faucet handle made of zinc alloy. refer to figure 1 , pre-treat the zinc alloy handle (1000 mesh sandpaper grinding-water washing-degreasing-water washing), then put it in an oven at 70°C, and dry it for 30 minutes; then spray white epoxy-polyurethane medium paint, and spray the medium paint. Put the storage board in the oven at 160°C and bake for 20 minutes; then spray the amber yellow acrylic-polyurethane primer and put it in the oven for 15 minutes at 50°C. After the baking is completed, take out the handle to prepare for the water transfer step; Set it to 25°C, then spread the water transfer film on the water surface with a water temperature of 25°C, wait for 2 minutes, then spray the activator, and press the handle into the water within 10 seconds after spraying the activator to transfer the water transfer film To the surface of the handle, after the transfer is completed, rinse the shelf with an automati...

Abstract

The invention discloses a water transfer printing preparation process applied to bathroom products. The water transfer printing preparation process comprises the following steps: spraying base coat onthe surface of the pretreated bathroom product, baking and curing, forming a transfer printing layer on the base coat of the bathroom product by a water coating technology or a water labeling technology, cleaning the surface of the bathroom product, and blowing away water on the surface of the transfer printing layer by adopting compressed air, and after baking, spraying finish paint, baking andcuring. According to the water transfer printing preparation process, the high-pressure water removal step is added after the cleaning step, water is blown away from the surface and then baking is carried out, the problems of bubbling, falling and the like caused by water spots formed after water is dried are solved, an improved water transfer printing product is free of abnormity after being boiled in water at 65 DEG C for 120 hours and tested in CASS for 100 hours, the performance is improved in a breakthrough mode, so that the water transfer printing product has long-term use reliability ina high-temperature and high-humidity bathroom environment.

Description

technical field [0001] The invention relates to the technical field of water transfer printing, in particular to a water transfer printing preparation process applied to bathroom products. Background technique [0002] The appearance effect that water transfer printing technology can produce is flexible and changeable, and various customized patterns can be produced on the surface of special-shaped products. Due to the characteristics of water transfer printing technology, this technology is very popular among product designers and has a wide range of applications. However, in the bathroom industry, water transfer printing technology has not yet been promoted. There are many types of base materials in the bathroom industry, and the application scenarios are mostly environments with high humidity, high temperature, and frequent use of detergents. Water transfer printing products often have defects such as coating blistering, peeling, and discoloration during use, which direc...
