Problems solved by technology

Existing silver powder coating materials will turn black or corrode after long-term use, and are also prone to discoloration due to alkaline water washing
[0004] In addition, the existing silver powder coating has limited shading effect and general adsorption effect. For the shading effect and service life, manufacturers often apply more than one layer of coating on the fabric
This behavior will cause silver-coated curtains to emit a certain pungent smell after being exposed to direct sunlight for a long time. It contains certain toxic components, such as silver powder, which may cause irreversible harm to the human body if used for a long time
In order to avoid the harm of silver powder, some manufacturers use aluminum powder instead of silver powder to achieve similar effects, but aluminum powder is not easy to characterize, and it is easy to fall off after a long time, which makes the appearance of silver-coated curtains unattractive

Embodiment 1-8

[0030] The preferred formula composition and mass parts thereof of the present embodiment are as shown in Table 1 below:

[0031]

[0032] testing method

[0033] The coating that obtains by the ratio of raw materials of present embodiment 1-8 is coated on curtain side, uses following method to detect:

[0034] 1. Flexibility, according to the test standard of GB / T 1731-93, the flexibility tester is fixed on the base by steel shaft rods with different diameters, and the coated side of the curtain cloth is pressed tightly on the base with both hands. On the shaft with a specified diameter, use the strength of two thumbs to bend around the shaft within 2-3 seconds. After bending and wrapping, the two thumbs should be symmetrical to the center line of the shaft. Finally, take it off and observe it with a 4x magnifying glass for comparison.

[0035]2. Weather resistance test, according to the test standard of GB / T 14522-2008, the simulation time is 1000 hours, the main method...

Embodiment 9-16

[0040] Example 8, the preferred formula obtained from the above experiment, added behenyl polyoxyethylene ether methacrylate (BEM) and silver glue, and at the same time, Example 7 was selected as a control example, and its specific mass parts are shown in 3:

[0041]

[0042] testing method

[0043] The coating that obtains by the raw material ratio of present embodiment 9-16 is coated on curtain side, uses following method to detect:

[0044] 1. Gloss value test, according to the test standard of GB / T9754-88, put the coated side of the curtain cloth on the vacuum plate facing up, and use a gloss meter to test under the specified incident angle.

[0045] 2. Weather resistance test, according to the test standard of GB / T 14522-2008, the simulation time is 1000 hours, the main method is to use the radiation of fluorescent ultraviolet lamp to simulate the ultraviolet radiation in sunlight, and directly shine on the coated curtain cloth one side. Simultaneously, the curtains ...

Abstract

The invention belongs to the field of adhesives, and particularly relates to an acrylic coating used for a curtain fabric and a preparation method of the acrylic coating. The acrylic coating is prepared from the following components, in parts by mass: 50 parts of acrylic acid, 18 parts of butyl acrylate, 5 parts of methyl acrylate, 5 parts of MMA, 20 parts of dihydroxyethyl acrylate, 3 parts of BEM, 15 parts of AIBN, 24 parts of tert-dodecyl mercaptan, 5 parts of diethyl ethanolamine, and 10 parts of a silver adhesive. The preparation method of the acrylic coating used for the curtain fabric comprises the following steps: sequentially adding the acrylic acid, the butyl acrylate, the methyl acrylate, the MMA, the dihydroxyethyl acrylate, the AIBN, the tert-dodecyl mercaptan and the diethylethanolamine into a stirring tank, and performing stirring for 30 min; adding the BEM, and performing stirring dispersion for 10 min; and adding the silver adhesive, and performing stirring for 30 min. The acrylic coating provided by the invention has good storage stability, a fast setting speed, strong color expression and long service life.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to an acrylic coating used for curtain cloth and a preparation method thereof. Background technique [0002] Curtains are a facility that every household has. The main function of curtains is to isolate from the outside world and maintain the privacy of the room. At the same time, it is an indispensable decoration for home decoration. In winter, curtains separate the indoor and outdoor into two worlds, adding warmth to the house. Modern curtains can not only reduce light and shading to meet people's needs for different intensity of light; Therefore, the ingenious combination of decoration and practicality is the biggest feature of modern curtains. [0003] Silver-coated curtains are a kind of blackout curtains that are more common and used by more people. The silver-coated curtain itself has better light-shielding properties, because the side of the curtain facing the light ...
