Embodiment 1

[0024] A kind of PVC film of this embodiment is laminated with waterproof fabric, with the fabric layer as the base layer, and a paint layer for increasing the look and feel is provided on one side of the fabric layer, and the paint layer is covered with a paint layer to keep the paint layer stable for long-term use. The film layer on the cloth layer; on the other side of the cloth layer, there is an adhesive layer pasted on the surface of the cloth layer by bronzing process, wherein the specific formula of each layer of material is as follows: cloth layer: including polyacrylic acid- 50-75% of 2-ethylhexyl fiber, 20-40% of polymethyl acrylate fiber and 20-35% of polyester fiber; coating layer: including 40-60% of butyl acetate and dibutyl diacetate in mass fraction Tin laurate 15-25%, iron red 10-15% and polyacrylamide 10-20%; film layer: including PVDF40-60% in mass fraction, sulfosuccinic acid alcohol ether ester 30-40% and oxidation Aluminum powder 20-35%; adhesive layer: ...

Embodiment 2

[0032] The present embodiment is further defined on the basis of the above-mentioned embodiment 1, including polyacrylate-2-ethylhexyl fiber 60%, polymethylacrylate fiber 20% and polyester fiber 20% in mass fraction; coating Layer: 55% butyl acetate, 15% dibutyltin dilaurate, 15% iron red and 15% polyacrylamide in mass fraction; film layer: 50% PVDF, sulfosuccinate in mass fraction Acid alcohol ether ester 30% and alumina powder 20%; adhesive layer: including hydrogenated nitrile rubber 70%, zinc oxide 9% and acetone 21% in mass fraction. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

Embodiment 3

[0034]The present embodiment is further defined on the basis of the above-mentioned embodiment 1, which includes 50% of polyacrylate-2-ethylhexyl fiber, 25% of polymethylacrylate fiber and 25% of polyester fiber in mass fraction Coating layer: including 40% butyl acetate in mass fraction, 25% dibutyltin dilaurate, 15% iron red and 20% polyacrylamide; film layer: including PVDF45% in mass fraction, sulfur 35% alcohol ether succinate and 20% aluminum oxide powder; adhesive layer: including 58% hydrogenated nitrile rubber, 12% zinc oxide and 30% acetone in mass fraction. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

Abstract

The invention discloses a PVC thin film laminated waterproof fabric. The PVC thin film laminated waterproof fabric comprises a fabric layer, a coating layer, a thin film layer and an adhesive pressinglayer; the specific formula of each layer of the material is as follows: the fabric layer is prepared from the following components in percentage by mass: 50 to 75 percent of polyacrylic acid-2-ethylhexyl ester fibres, 20 to 40 percent of polymethyl methacrylate fibres and 20 to 35 percent of polyester fibres; the coating layer comprises the following components in percentage by mass: 40 to 60 percent of butyl acetate, 15 to 25 percent of dibutyltin dilaurate, 10 to 15 percent of iron oxide red, and 10 to 20 percent of polyacrylamide; the thin film layer is prepared from the following components in percentage by mass: 40 to 60 percent of PVDF, 30 to 40 percent of sulfonyl succinate and 20 to 35 percent of alumina powder; the adhesive pressing layer is prepared from the following components in percentage by mass: 45 to 85 percent of hydrogenated nitrile rubber, 8 to 16 percent of zinc oxide and 20 to 30 percent of acetone. According to the PVC thin film laminated waterproof fabric, awaterproof effect can be improved through a four-layer structure; the thin film layer arranged on the coating layer can prevent the coating from being worn greatly after long-term use.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a PVC film laminated waterproof fabric. Background technique [0002] The main functions of waterproof and breathable fabrics are: waterproof, moisture permeable, breathable, insulating, windproof, and warm. In terms of production process, the technical requirements of waterproof and breathable fabrics are much higher than that of ordinary waterproof fabrics; at the same time, in terms of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof and breathable fabric not only enhances the airtightness and watertightness of the fabric, but also its unique vapor permeability can quickly discharge the water vapor inside the structure, avoid the growth of mold in the structure, and keep the human body dry all the time. It perfectly solves the problem of breathability, windproof, waterproof, It is a new type of fabric ...
