Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of window films, in particular to an energy-saving window film, a preparation method and applications. Background Art
[0002] At present, the curing process of the hardened coating of window film is UV curing. UV curing requires a photoinitiator to absorb ultraviolet light and release free radicals to initiate curing. Excellent weather resistance requires the addition of more ultraviolet absorbers and ultraviolet stabilizers. If too much ultraviolet absorber and ultraviolet stabilizer is added, the hardened coating will not be completely cured during UV curing and will not meet the hardness requirements. If it is changed to a thermosetting process, the production efficiency will be very low due to the long thermosetting time, and the hardness of the hardened coating will be low. These problems cannot be solved by the thermosetting process. There is an urgent need for a production process to replace UV and thermosetting to achieve both high production efficiency and meet the hardness and weather resistance requirements.
[0003] Automotive window film has evolved from its first generation to its fifth generation, becoming an essential component of every car. While the domestic market is rife with domestic automotive window film brands, they often operate at a low price point with a short lifespan, resulting in little customer acceptance. Foreign companies like 3M, LLumar, and V-KOOL dominate the market, leaving virtually no domestic automotive window film manufacturers comparable to established brands like 3M, LLumar, and V-KOOL.
[0004] The process used for the surface hardening coating of automobile window films is also UV curing. UV curing requires the addition of photoinitiators, which results in small molecules remaining in the surface hardening coating, thereby affecting the heat insulation effect of the surface hardening coating. There is an urgent need for a production process to replace UV to avoid small molecule residues. Summary of the Invention

[0068] Table 1 Performance test of energy-saving window films prepared in Examples 1-24:
[0069] From the results in Table 1, it can be concluded that in the EB glues with TBCHA, TMCHA and CTFA, TBCHA and CTFA will have residual glue, only TMCHA will not have residual glue, which means that TMCHA has better high temperature resistance and hydrolysis resistance; the EB glue containing CTFA has the worst 180-degree peel strength, which means that CTFA cannot provide better peel strength; TBCHA, TMCHA and CTFA have little effect on haze, mainly because the main resin has a greater impact. The results show that the EB glue containing BR-3641AJ and BR-3741AJ has better transmittance and lower haze; the EB glue containing BR-3042 has the worst yellowing resistance, which means that the aromatic polyurethane acrylate BR-3042 cannot provide better yellowing resistance; in summary, in Example 12, the EB glue using TMCHA and BR-3641AJ has the most suitable performance in weather resistance, transmittance, haze and yellowing resistance.

[0080] Table 2 Energy-saving window film performance test
[0081] It can be concluded from Table 2 that the higher the functional group, the higher the pencil hardness. The functional groups of GU9315Z used in Example 29 are 12-15, and the others are all 6. The results of the double 85 performance test show that the higher the functional group, the higher the cross-linking density, and the less the infrared blocking rate decreases. There is little difference in yellowing resistance. In summary, in Example 29, the energy-saving window film prepared using EB glue configured with TMCHA and BR-3641AJ and EB thermal insulation coating configured with GU9315Z has the best performance.
[0082] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
