preparation example Construction

[0152] like Figure 5 As shown, the embodiment of the present application also provides a method for preparing a unidirectional laminate, including:

[0153] S501: Prepare a plurality of single layers, wherein any single layer is prepared by continuously spreading multiple ultra-high molecular weight polyethylene films or strips in sequence, and every two continuously spread ultra-high molecular weight polyethylene films or strips The adjacent part of the band is a neighboring area.

[0154] S502: Coating an adhesive on at least one side of at least one single layer.

[0155] S503: With at least one surface coated with the adhesive as an adjacent surface, each adjacent region of one single layer is staggered from each adjacent region of another adjacent single layer, In a state where the multiple single layers are respectively parallel and any two adjacent single layers are at least partially overlapped, the multiple single layers are bonded into a unidirectional laminate. ...

Embodiment 1

[0170] Use ultra-high molecular weight polyethylene film to prepare unidirectional laminate, wherein the ultra-high molecular weight polyethylene film has a width of 120mm, a thickness of 0.025mm, a linear density of 19000D, a breaking strength of 27 g / denier, and a tensile modulus of 1600 g / denier, elongation at break 1.9%. The number of sheets of ultra-high molecular weight polyethylene film required for a single layer can be determined according to the width of the required single layer and the width of a single ultra-high molecular weight polyethylene film. Adjacent to parallel spreading to form a single layer; after preparing two single layers respectively, the lower surface of each single layer is coated with adhesive by dimple coating, the adhesive is KratonD1161, and the amount of glue is 5.8%; Each adjacent area of ​​the single layer is staggered from each adjacent area of ​​another single layer, and the two single layers are parallel and overlapped at least partially...

Embodiment 2

[0174] UHMWPE tapes are used to prepare unidirectional laminates. Each UHMWPE tape has a width of 50mm, a thickness of 0.012mm, a linear density of 5000D, and a breaking strength of 29 g / denier. The weight was 1800 g / denier and the elongation at break was 1.7%. The number of sheets of ultra-high molecular weight polyethylene strips required for a single layer can be determined according to the width of the required single layer and the width of a single ultra-high molecular weight polyethylene strip, such as 24 pieces of the above-mentioned ultra-high molecular weight polyethylene strips The tapes are spread in parallel with a small gap (less than 2mm) to form a single layer; after preparing two single layers respectively, the lower surface of at least one single layer is coated with a dimple coating. The adhesive is water-based polyurethane Emulsion, the amount of sizing is 10%; each adjacent area of ​​one single layer is staggered from each adjacent area of ​​another single ...

Abstract

The invention discloses a unidirectional laminate and a preparation method thereof as well as a system, a non-woven fabric and a protective product. The system comprises a preparation control subsystem, an adhesive-coating control subsystem and an adhesion control subsystem, wherein the preparation control subsystem is used for preparing a plurality of single layers, any one single layer is prepared in a way of continuously spreading a plurality of ultra-high molecular weight polyethylene films or strips, and the adjacent position of the every two continuously-spread ultra-high molecular weight polyethylene films or strips is an adjacent area; the adhesive-coating control subsystem is used for coating at least one surface of at least one single layer with an adhesive; the adhesion control subsystem is used for adhering the single layers into the unidirectional laminate through taking at least one surface coated with the adhesive as an adjacent surface under the conditions that the adjacent areas of one single layer are mutually staggered with the adjacent areas of the adjacent single layer, the single layers are parallel, and any two adjacent single layers are at least locally superposed. The preparation method is simple, easy to implement and high in efficiency; the unidirectional laminate, the non-woven fabric and the protective product have the advantages of being light in weight, good in rigidity and protection performance, and the like, and is wide in application.

Description

technical field [0001] The application relates to the technical field of application of polymer materials, in particular to a unidirectional laminate and its preparation method and system, non-weft cloth and protective products. Background technique [0002] Ultra High Molecular Weight Polyethylene (UHMW-PE for short) is a thermoplastic engineering plastic with a linear structure and excellent comprehensive properties. Making high-strength fibers based on this material is one of its most important uses. [0003] Ultra-high molecular weight polyethylene (UHMW-PE) fiber is a kind of synthetic fiber. Its molecular structure has a high degree of straightening parallelism and orientation. This molecular structure determines that UHMW-PE fiber has extremely high strength. And modulus, and has good chemical stability, corrosion resistance and other advantages. The above-mentioned characteristics of ultra-high molecular weight polyethylene (UHMW-PE) fibers have surpassed the plain ...
