Problems solved by technology

[0002] In the past technology, polyester (polyester, PET) film with appropriate thickness is often used as a thermal insulation film patch. Although this single-layer PET film has appropriate strength, its effect on resisting light is not good. Better, in order to make the PET film have better anti-infrared and anti-ultraviolet capabilities, sometimes the industry will cover the surface of the PET film with a thin layer containing metals such as nickel, silver, aluminum, chromium, etc., or add a layer containing organic Dyed TLC
Although the design of the aforementioned metal or dyed thin layer can increase the anti-infrared and anti-ultraviolet effects of the patch, the thin metal layer sometimes hinders the signal reception of communication equipment, resulting in poor reception quality in the surrounding environment, and the dyed thin layer Due to the influence of dyes gradually fading by sunlight, the thermal insulation effect will be reduced. Therefore, the thermal insulation film patch based on polyester film is not ideal for use in the past.

Embodiment 1

[0016] Refer to figure 1 The multi-layer heat insulation film patch 1 of this embodiment can be pasted on a substrate 10 such as glass, lens, etc., and includes: a base unit 11, an infrared-resistant layer 12, and a scratch-resistant and wear-resistant layer 13. And an anti-ultraviolet layer 14. The base unit 11 is formed by alternately stacking a plurality of spaced first base films 111 and a plurality of second base films 112 between adjacent first base films 111. The first and second The total number of the two base films 111 and 112 is 100 layers. In general, the base unit 11 has a first surface 113 adjacent to the anti-infrared layer 12 and a second surface 114 adjacent to the anti-ultraviolet layer 14, and The thickness of the outermost layer forming the first or second surface 113, 114 of the aforementioned base film 111, 112 is greater than that located in the middle, and the anti-ultraviolet layer 14 can be directly attached to the substrate 10, and the anti-scratch and w...

Embodiment 2

[0024] The composition ratios and processing conditions of the components of Example 2 of the present invention are roughly the same as those of Example 1. The difference is that the number of layers of the base unit 11 is increased to 200. Due to the increase in the number of layers, the total thickness of the base unit 11 Increase to 35μm. After manufacturing, various experiments such as infrared resistance, ultraviolet resistance, impact resistance, and visible light transmittance were also carried out. The experimental results are also shown in Table 1.

Embodiment 3

[0026] The composition ratios and processing conditions of the components of Example 3 of the present invention are also the same as those of Example 1. The difference is that the number of layers of the base unit 11 is reduced to 20, and the overall thickness of the base unit 11 is reduced to 18 μm. After manufacturing, various experiments such as infrared resistance, ultraviolet resistance, impact resistance, and visible light transmittance were also carried out. The experimental results are also shown in Table 1.

Abstract

The invention discloses a multilayer heat insulating membrane patch for insulating heat from sunshine, comprising a base layer unit stacked by 20-200 layers basal membrane and an infrared ray resistant layer, a scratch-resistant and wearing-proof layer and an ultraviolet ray resistant layer that are directly or indirectly combined with the basal membrane. The thickness of the basal membrane of the base layer unit is within the visible wavelength range and made from two different materials, the infrared ray resistant layer is prepared by adding 0.5-1.0 wt% infrared ray resistant nanometer particles in a matrix, the ultraviolet ray resistant layer is made of resin containing 0.3-0.7 wt% benzotriazole, and the scratch-resistant and wearing-proof layer is made of polyester compound containing 0.2 wt% lanthanum hexaboride. By the combination of the above layers, the patch has proper light transmittance and better effects of ultraviolet ray resistant, infrared ray resistant, scratch-resistant and wearing-proof.

Description

Technical field [0001] The present invention relates to a multi-layer heat insulation film patch, in particular to a multi-layer heat insulation film patch suitable for being attached to the surface of substrates such as glass, lenses, etc., and used to block sunlight heat sources. Background technique [0002] In the past technology, polyester (PET) film with an appropriate thickness is often used as a heat-insulation film patch. Although this single-layer PET film has appropriate strength, its effect of resisting light is not Preferably, in order to make the PET film have better infrared and ultraviolet resistance, sometimes the industry will cover the surface of the PET film with a thin layer containing metals such as nickel, silver, aluminum, chromium, or add a layer containing organic A thin layer of dye. Although the aforementioned metal or dyed thin layer design can increase the anti-infrared and anti-ultraviolet effect of the patch, the metal thin layer sometimes hinders ...
