Problems solved by technology

But there is no research on the application of UHMWPE fiber to the field of architectural membrane materials
One of the problems is that the surface of UHMWPE fiber is inert, and it is not easy to compound with polymer materials used in architectural membrane materials, thus limiting the application of UHMWPE fibers in architectural membrane materials.

Embodiment 1

[0040] (1) Immerse the UHMWPE fiber plain weave in acetone, place it in an ultrasonic cleaning machine for ultrasonic treatment for 10 minutes, and complete the impurity removal treatment for the UHMWPE fiber plain weave. Then use deionized water to ultrasonically clean the UHMWPE fiber plain cloth after cleaning for 10 minutes. Dry the cleaned UHMWPE fiber plain cloth at 50°C for 2h. Then, the UHMWPE fiber plain weave is subjected to plasma treatment with a plasma surface treatment machine to realize the surface modification treatment of the UHMWPE fiber plain weave. The output power of the plasma treatment is 45W, the treatment time is 60s, and the treatment gas is nitrogen. The UHMWPE fiber plain cloth is woven from UHMWPE fiber of model AC1600 produced by Anhui Weiya New Material Technology Co., Ltd.

[0041] (2) Submerge the UHMWPE fiber plain weave cloth after the surface modification treatment in the water-based polyurethane emulsion, then place it in an ultrasonic cle...

Embodiment 2

[0049] The difference from Example 1 is that in step (3), both sides of the dried UHMWPE fiber plain weave cloth in step (2) are hot-compressed with a PES adhesive film, and the PES adhesive film is Shanghai The F908 adhesive film produced by Tianyang Hot Melt Adhesive Material Co., Ltd.; the compounding temperature is 120°C, the compounding pressure is 0.12MPa, and the compounding speed is 15m / s. After compounding, a composite film material is obtained.

[0050] All the other steps are the same as in Example 1.

[0051] Because the difference between this embodiment and embodiment 1 is only in step (3), the treatment process to UHMWPE fiber plain weave is the same, because the mechanical properties such as tensile strength, tear resistance and bursting strength of the composite film are mainly Provided by UHMWPE fiber, the adhesive film is mainly used to protect the UHMWPE fiber structure and provide stress dispersion and conduction. Since the main structure of the fiber in t...

Embodiment 3

[0053] (1) Submerge the UHMWPE fiber twill cloth in acetone, place it in an ultrasonic cleaning machine for ultrasonic treatment for 20 minutes, and complete the impurity removal treatment for the UHMWPE fiber twill cloth. Then use deionized water to ultrasonically clean the UHMWPE fiber twill cloth after cleaning for 20 minutes. Dry the cleaned UHMWPE fiber twill at 50°C for 1 hour. Then use a corona treatment machine to corona treat the UHMWPE fiber twill fabric to realize the surface modification treatment of the UHMWPE fiber twill fabric. The treatment voltage of the corona treatment is 10kV, the treatment time is 20s, and the treatment gas is air. The UHMWPE fiber twill fabric is woven from UHMWPE fiber of model AC1600 produced by Anhui Weiya New Material Technology Co., Ltd.

[0054] (2) Submerge the UHMWPE fiber twill cloth after the surface modification treatment in the water-based epoxy resin emulsion, and then place it in an ultrasonic cleaning machine for ultrasoni...

Abstract

The invention relates to a composite membrane material and a preparation method thereof, and belongs to the technical field of building membrane materials. The material consists of a fabric containing UHMWPE (Ultra High Molecular Weight Polyethylene) fibers subjected to surface modification treatment, a macromolecular coupling agent and a thermoplastic resin adhesive film, the surface modification treatment method is a plasma treatment method or a corona treatment method. The preparation method comprises the following steps: carrying out surface modification treatment on UHMWPE (Ultra High Molecular Weight Polyethylene) fibers or a fabric only formed by the UHMWPE fibers, immersing in a polymer coupling agent emulsion, and drying; other textile fibers and the UHMWPE fibers are jointly woven into a fabric, and the fabric and the thermoplastic resin adhesive film are subjected to hot-pressing compounding. Or the fabric only formed by the UHMWPE fibers and the thermoplastic resin adhesive film are subjected to hot-pressing compounding. According to the method, the surface inertness and hydrophobicity of the UHMWPE fiber are improved, and the UHMWPE fiber is compounded with a thermoplastic resin adhesive film.

Description

technical field [0001] The invention relates to a composite membrane material and a preparation method thereof, belonging to the technical field of architectural membrane materials. Background technique [0002] Architectural membrane materials are the fifth building materials after steel, cement, wood and glass. At present, the basic structure of architectural membrane materials is to use the fabric formed by polyester filament or glass fiber as the base cloth, and set the polymer coating on one or both sides of the base cloth by thermal bonding or coating; Functional materials are set on the polymer coating to meet diverse application requirements. The base fabric in architectural membrane materials is generally woven fabric. The base fabric determines the mechanical properties of architectural membrane materials and mainly provides mechanical properties; the polymer coating plays a role in protecting the base fabric and mainly ensures the compactness of architectural mem...
