Description

Technical Field

[0001] The utility model relates to the technical field of cloth structures, in particular to a silicone coated composite curtain cloth. Background Art

[0002] Glass fiber composite curtain fabric is a newly developed curtain product for household and industrial use. Glass fiber curtain fabric has good mechanical properties, flame retardancy, heat insulation, mildew resistance, antibacterial and self-cleaning properties, and is widely used in high-end hotels, office buildings, offices and high-end residences. However, the current glass fiber curtain fabric generally uses PVC coating, which has poor anti-aging performance. After years of use, it is easy to turn yellow, and color difference, yellow spots and other effects will affect the appearance.

[0003] For example, CN207523128U discloses a low-density glass fiber curtain fabric, including a base fabric, a PVC mask layer on the upper surface of the base fabric, an upper adhesive layer between the PVC mask layer and the base fabric, a PVC bottom film layer on the lower surface of the base fabric, and a lower adhesive layer between the PVC bottom film layer and the base fabric.

[0004] The PVC mask layer is used in the above-mentioned low-density glass fiber curtain fabric, which has poor anti-aging performance. After long-term use, it is easy to have yellowing color difference, yellow spots and other problems that affect the appearance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a silicone coated composite curtain fabric to solve the problem in the prior art that the anti-aging performance is poor and yellowing, color difference, yellow spots, etc. may occur after long-term use, affecting the appearance.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: a silicone coated composite curtain fabric, comprising a first silicone impregnated coating, a glass fiber cloth, a second silicone impregnated coating and a silicone scraping coating arranged in sequence from top to bottom.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The silicone-coated composite curtain fabric is mainly composed of a first silicone impregnated coating, a glass fiber cloth, a second silicone impregnated coating and a silicone scrape coating. The first silicone impregnated coating and the second silicone impregnated coating are formed on the surface of the glass fiber cloth, which improves the flatness of the product and makes the texture denser. The product is also easy to clean and has improved aging resistance. During long-term use, problems such as yellowing, color difference and yellow spots will not occur. The silicone scrape coating is combined on the second silicone impregnated coating to further improve the flatness and aging resistance of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of an embodiment of the utility model.

[0010] The reference numerals in the drawings of the specification include: a first silicone dip coating 1, a glass fiber cloth 2, a second silicone dip coating 3, and a silicone scraping coating 4. DETAILED DESCRIPTION

[0011] The utility model is further described in detail below through specific implementation methods:

[0012] like Figure 1 As shown, an embodiment of the utility model provides a silicone coated composite curtain fabric, comprising a first silicone impregnated coating 1, a glass fiber cloth 2, a second silicone impregnated coating 3 and a silicone scraping coating 4 arranged in sequence from top to bottom.

[0013] The silicone coated composite curtain fabric is mainly composed of a first silicone impregnated coating 1, a glass fiber cloth 2, a second silicone impregnated coating 3 and a silicone scraping coating 4. The first silicone impregnated coating 1 and the second silicone impregnated coating 3 are formed on the surface of the glass fiber cloth 2, which improves the flatness of the product and makes the texture denser. The product is also easy to clean and has improved aging resistance. During long-term use, problems such as yellowing, color difference and yellow spots will not occur; and the silicone scraping coating 4 is combined on the second silicone impregnated coating 3 to further improve the flatness and aging resistance of the product.

[0014] like Figure 1 As shown, according to another embodiment of the utility model, the silicone coated composite curtain fabric, wherein the glass fiber fabric 2 has a thickness of 0.2mm-0.6mm and a gram weight of 300g / ㎡-600g / ㎡. Specifically, the thickness of the glass fiber fabric 2 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm or 0.6mm, etc., and the gram weight can be 300g / ㎡, 400g / ㎡, 500g / ㎡ or 600g / ㎡, etc.
