Embodiment 1

[0029] Embodiment 1: as attached figure 1 As shown, a high-barrier file cabinet dust-sealing material, from top to bottom, includes PVC plastic pulp layer I1, PVC plastic pulp with adhesive I2, high-strength polyester woven fabric 3, and PVC plastic pulp with adhesive Ⅱ4, PVC plastic slurry layer Ⅱ5, PVDC film layer 6 and PVC film layer 7, the PVC plastic slurry layer I1, PVC plastic slurry I2 with adhesive, high-strength polyester woven fabric 3, PVC plastic with adhesive After laminating the slurry II4 and the PVC plastic slurry layer II5, a PVC knife-coated cloth is obtained, and the PVC knife-coated cloth is laminated with the PVDC film layer 6 and the PVC film layer 7 in sequence.

[0030] The PVC plastic layer I1, PVC plastic layer II5 and PVC film layer 7 all include PVC resin, plasticizer, stabilizer, flame retardant and pigment.

[0031] The pigments in the PVC plastic pulp layer I1 and PVC plastic pulp layer II5 are yellow, the flame retardant is a mixture of antimo...

Embodiment 2

[0034] Embodiment 2: A preparation method of a high-barrier filing cabinet dust-sealing material, comprising the following steps,

[0035] a: The PVC film layer 7 is obtained by calendering; after the PVC resin, plasticizer, stabilizer and flame retardant are mixed uniformly, the PVC film layer 7 is formed after being heated and calendered in a calender and cooled; the PVC film layer 7 The thickness is 0.06 mm;

[0036] b: Polyurethane water-based two-component glue is coated on both sides of the PVDC film to obtain the PVDC film layer 6; the temperature for coating the glue is 65°C; the thickness of the PVDC film layer 6 is 0.02 mm;

[0037]c: The front and back sides of the high-strength polyester woven fabric 3 are coated with PVC plastic pulp I2 with adhesive and PVC plastic pulp II4 with adhesive under vertical primer respectively by knife coating method, and the PVC plastic pulp layer is applied again Ⅰ1 and PVC plastic slurry layer Ⅱ5, then dried and plasticized, and c...

Abstract

The invention discloses a high-barrier filing cabinet dust sealing material which sequentially comprises a PVC plastic paste layer I, a PVC plastic paste layer I with an adhesive, a high-strength polyester woven fabric, a PVC plastic paste layer II with an adhesive, a PVC plastic paste layer II, a PVDC film layer and a PVC film layer from top to bottom, wherein the PVC plastic paste layer I, the PVC plastic paste layer I with the adhesive, the high-strength polyester woven fabric, the PVC plastic paste layer II with the adhesive and the PVC plastic paste layer II are bonded to obtain PVC knifescraping coating cloth, and the PVC knife scraping coating cloth is sequentially bonded to the PVDC film layer and the PVC film layer. The high-barrier filing cabinet dust sealing material has the advantages of high strength, high barrier, good air tightness, excellent peeling strength and good moisture-proof and environment-friendly performance.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a high-barrier filing cabinet dust sealing material and a preparation method thereof. Background technique [0002] At present, the plastic moisture-proof envelope is a kind of flexible packaging container. Sealing products with envelopes is a follow-up to cocoon-style anti-corrosion [0003] A new type of protective packaging method developed after protective packaging technology. Cocoon packaging has more advantages, such as light weight, low cost, and convenient use. The application of this technology is a major innovation in modern packaging and sealing technology. [0004] Plastic moisture barrier envelope materials are used the most. There are also many types of materials, including transparent and opaque, single-layer film, and multi-layer composite. The materials currently used are as follows: [0005] 1. Polyethylene (PE) film, because polyethyl...
