Description

Technical Field

[0001] The invention belongs to the technical field of fabrics, and in particular relates to an ultra-high molecular weight polyethylene mesh fabric. Background Art

[0002] Ultra-high molecular weight polyethylene (UHMWPE) has many unique properties, such as excellent wear resistance, impact resistance, chemical resistance and low friction coefficient. However, the application of UHMWPE in mesh fabrics is usually made of materials such as polyester or nylon. Although these materials have certain strength and wear resistance, their performance may not meet the requirements in some applications. Therefore, a new type of mesh fabric is needed to improve its performance and service life.

[0003] Under normal circumstances, ultra-high molecular weight polyethylene and PVC coating cannot be integrated. This invention uses temperature control and modified PVC to integrate the two, which makes the impossible possible and creates a new material with airtightness function, thereby improving the stability of the finished product processing technology and greatly reducing costs. Summary of the invention

[0004] Problems with existing technologies:

[0005] There is currently no technology for applying UHMWPE to mesh fabrics, and the performance requirements of wear resistance, impact resistance, chemical corrosion resistance and low friction coefficient cannot be met.

[0006] The technical solution adopted by the present invention is as follows: an ultra-high molecular weight polyethylene mesh fabric, comprising a fabric layer and a PVC coating, wherein the fabric layer is an ultra-high molecular weight polyethylene mesh fabric, and the PVC coating is coated on the surface of the fabric layer.

[0007] Furthermore, the ultra-high molecular weight polyethylene mesh cloth is woven from ultra-high molecular weight polyethylene fibers, and the diameter of the ultra-high molecular weight polyethylene fibers is 5-10 μm.

[0008] Furthermore, the thickness of the PVC coating is 0.1-0.5 mm.

[0009] Furthermore, the thickness of the ultra-high molecular weight polyethylene mesh cloth is 0.5-1.5 mm.

[0010] Furthermore, the tensile strength of the ultra-high molecular weight polyethylene mesh cloth is 2000-3000 MPa, and the elongation at break is 10-20%.

[0011] Furthermore, the tensile strength of the PVC coating is 10-20 MPa, and the elongation at break is 200-300%.

[0012] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0013] The ultra-high molecular weight polyethylene mesh fabric has excellent wear resistance, impact resistance, chemical corrosion resistance and low friction coefficient, and has good strength and toughness. It is suitable for making various wear-resistant, impact-resistant and chemical-resistant products, such as conveyor belts, protective clothing, filter cloth, etc. DETAILED DESCRIPTION
