Table 4: performance test data sheet
Figure BDA0003919342060000091
Figure BDA0003919342060000101
From examples 1-3, it can be seen that the TPU film prepared herein has excellent abrasion resistance and strength while ensuring good texture. Application examples further prove that the TPU film composite wall cloth prepared by the method improves the waterproofness of the wall cloth, improves the binding force between the TPU film and the wall cloth, and reduces the phenomena of moisture and easy shedding of the wall cloth.
By adding the diatomite into the TPU polyurethane system, the lubricating property and the strength of the TPU film are improved, the binding force between the TPU film and the wall cloth can be enhanced, and the phenomenon that the wall cloth is easy to fall off is reduced. On the other hand, the porous structure of the diatomite can be better combined with TPU polyurethane, and hydrogen bonding effect is generated, so that better combination of the TPU film and the wall cloth is further promoted. Comparative example 5 compared with example 1, it can be seen from the performance test results that comparative example 5 uses a common commercially available lubricant, and although it can provide a certain lubricating effect, the mutual bonding between molecules in the TPU polyurethane system may be reduced, and thus the performance of the TPU film and the TPU composite wall cloth may be affected.
The ABS resin is added into the TPU polyurethane system, so that the matte effect, the heat resistance, the water resistance and the strength of the TPU film are improved. Meanwhile, TPU polyurethane and ABS resin are well combined, and the binding force among molecules of a TPU film system is further enhanced. Examples 4 and 5 compared with example 1, the ABS resin has different usage amounts of acrylonitrile, butadiene and styrene, wherein the performance of example 1 is optimal, and the TPU prepared by controlling the usage amounts of the acrylonitrile, the butadiene and the styrene simultaneously has better heat resistance, strength and toughness. The prepared TPU composite wall cloth has more excellent stability, and the phenomena that the wall cloth is affected with damp and is easy to fall off are reduced. Compared with the prior art, the performance of the TPU film and TPU film composite wall cloth is reduced by adopting the common commercial matte agent in the comparative example 6, and the ABS resin is further used for improving the matte effect of the TPU film and promoting the combination of molecules of a TPU film system.
From examples 6 to 9, it can be seen that the addition of titanium dioxide to the ABS resin improves the UV resistance of the TPU film and reduces the discoloration of the TPU film by the mutual combination of titanium dioxide and ABS resin. Meanwhile, the titanium dioxide is combined with the hollow microporous structure of the diatomite, so that the titanium dioxide is uniformly dispersed in the TPU polyurethane system, and the stability of the TPU film is further improved. The titanium dioxide used in examples 6-9 was different, wherein the titanium dioxide used in example 6 was the most preferred, while the titanium dioxide used in example 9 was too much, which decreased the performance of the TPU film, indicating that excessive titanium dioxide may cause particle agglomeration and affect the stability of the TPU film.
From examples 10 to 12, it can be seen that the addition of the silica sol to the TPU polyurethane system can promote the adhesion between the components of the TPU polyurethane system and also can generate a chemical force with the hydroxyl groups of the diatomaceous earth, thereby enhancing the bonding force between the molecules of the TPU polyurethane system, further improving the bonding between the TPU film and the wall cloth, and reducing the phenomenon that the wall cloth is easy to fall off. Meanwhile, when the TPU film is compounded with the wall cloth, the silica sol can promote the TPU film to be better combined with the wall cloth, so that the binding force between the TPU film and the wall cloth is further improved, and the phenomenon that the TPU composite wall cloth falls off is reduced. In examples 10 to 12, the amount of silica sol used was varied, and the performance of example 10 was the best.
From examples 13-16, it can be seen that the addition of polyethylene wax to the TPU polyurethane system reduces the coefficient of friction of the TPU film and improves the abrasion resistance and scratch resistance of the TPU film. Meanwhile, the polyethylene wax is used for film forming protection of the TPU film, and the lubricating property and stability of the TPU film are improved, so that the waterproof property and stability of the TPU film composite wall cloth are improved, and the phenomena that the wall cloth is affected with damp and is easy to fall off are reduced. In examples 13-15, the polyethylene wax was used in the most preferred amount in example 13. In example 16, the other compound was used instead of polyethylene wax, and the test results show that the performance of the TPU film is slightly reduced, which indicates that the performance of polyethylene wax is better.
In example 17, titanium dioxide, silica sol, and polyethylene wax are added at the same time, and it can be seen from the detection results that, in example 17, compared with the detection results of examples 10 and 13, the performance of the TPU film and the TPU composite wall cloth of example 17 is greatly improved, which further illustrates that, under the synergistic effect of the mutual combination of the molecules in the application, the prepared TPU film and the wall cloth can be better combined, and the prepared TPU composite wall cloth has excellent waterproofness and stability, and reduces the phenomena that the TPU composite wall cloth is wetted and easily falls off.
Comparative examples 1 and 3 it can be seen that the absence of either of the diatomaceous earth and ABS resin has some effect on the strength and stability of the TPU film. So that the performance of the TPU composite wall cloth can be influenced. In comparative examples 2 and 4, too much diatomite and ABS resin are used to cause the performance of the TPU film to be reduced, which shows that the excessive diatomite and ABS resin can affect the combination between the TPU polyurethane system molecules, thereby causing the performance of the TPU film to be reduced and further affecting the combination of the TPU film and the wall cloth.
In application example 24, a common commercially available TPU film is combined with wall cloth, and although the TPU film still has a certain waterproof property, the detection result shows that the bonding force between the TPU film and the wall cloth is significantly reduced, which indicates that the TPU film can promote better bonding between the TPU film and the wall cloth under the mutual bonding effect of the components, and further indicates that the TPU film composite wall cloth prepared by the method has better stability.
The specific embodiments are only for explaining the present application and are not limiting to the present application, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present application.
