Then, the water-based acrylic resin glass fiber composite plate is cut to obtain the mold-resistant substrate 10.

Please refer to FIGS. 1 to 3, the step S2 of disposing the pattern layer 20 on the first surface 11 of the anti-mildew substrate 10 to obtain the anti-mildew wall sticker is described in detail as follows: applying a foam material to On the first surface 11 of the mold-proof substrate 10, a mold-proof substrate coated with the foam material is obtained. Then, under the conditions of a foaming temperature of 200° C. and a foaming time of 1 minute, the foaming material is foamed to form a foaming layer 21 on the mold-resistant substrate 10. Next, color printing is performed on the surface of the foam layer 21 to form a color layer 22 on the surface of the foam layer 21. Next, the color layer 22 and the foam layer 21 are embossed to form a texture region 23 on the color layer 22 and the foam layer 21, and the pattern layer 20 and a mold-resistant substrate with the pattern layer are obtained . Then, the mold-proof substrate with a pattern layer is cut to obtain the mold-proof wall sticker. The pattern layer 20 includes the color layer 22, the foam layer 21, and the texture area 23.

Comparative example: Material comparison of anti-mold wall stickers

In order to verify the influence of material selection on the characteristics of anti-mold wall stickers, this experiment also used a combination of glass fiber cloth of different materials and different resins for tensile test, dipping test and coating test. In different experimental groups, the glass fiber cloths used are: long fiber glass fiber blankets, short fiber glass fiber blankets and industrial glass fiber cloths produced by Taiwan Glass Co., Ltd.; long fiber strong glass from Australian brands Fiber blanket; and electronic grade continuous glass fiber cloth (product model 7628) produced by Fuqiao Industrial Co., Ltd. The resin materials used can be: water-based acrylic resin (select the product model P104 produced by the industry association company) and oily resin (polyvinyl acetate (PVAC)). The experimental results are shown in Table 1 below: Table 1 Comparison test results of materials for anti-mold wall stickers

In the above three tests, the subsequent immersion test and coating test will only be carried out when the anti-mold wall sticker can successfully pass the tensile test; when the anti-mold wall sticker does not pass the tensile test (break), the subsequent dip will not be performed Shower test and coating test.

In addition, the combination of electronic grade continuous glass fiber cloth and aqueous acrylic resin listed in the above table represents the results of the foregoing Example 1, and the remaining experimental groups are comparative examples of Comparative Example 1. The tensile test is to pull the glass fiber of each material by human power, and then observe whether the glass fiber has sufficient tensile strength tolerance; the immersion test corresponds to the immersion glass fiber of the manufacturing method of the anti-mold wall sticker in the foregoing Example 1 The step of obtaining the anti-mold substrate in the resin, and then pulling with 20 kg/m ² of the machine, and observing whether the glass fiber is intact or broken; finally, the coating test corresponds to the manufacturing method of the anti-mold wall sticker in Example 1 The step of providing a pattern layer (including PVC material) on the surface of the anti-mold substrate to obtain the anti-mold wall sticker is mainly to observe whether the surface of the anti-mold wall sticker is smooth and flat.

From the above experimental results, it can be seen that the wall stickers produced by the electronic grade continuous glass fiber cloth (product number 7628) produced by Fu Qiao Industrial Co., Ltd. have good tensile strength and can withstand immersion on the machine. The cloth also has a smooth surface, which is the first choice for making anti-mold wall stickers; the second is the industrial glass fiber cloth produced by Taiwan Glass Co., Ltd. In addition, although the water-based acrylic resin and the oil-based resin have good tensile strength on the electronic grade continuous glass fiber cloth, however, considering that the oil-based resin cannot adhere well to the cement wall, the present invention decided to use the water-based acrylic resin .

In summary, the anti-mold wall sticker of the present invention not only has the advantages of not being mildew-proof but can maintain a good decorative effect, has a long service life and does not affect environmental hygiene, but also has good fire resistance, corrosion resistance, moth resistance, and heat insulation The characteristics of sound insulation and sound insulation can meet the decoration needs of buildings with many different uses, so it has a wide range of applications.
