Abstract

The invention discloses a polyurethane anti-glare net and a production process. The anti-glare net comprises an anti-glare net body, which is prepared from a polyurethane elastomer as a base materialand glass fibers as a reinforcing material through a continuous drawing extrusion process, wherein the glass fibers account for 50-90% of the total weight, and the polyurethane elastomer accounts for10-50% of the total weight. According to the invention, the polyurethane anti-glare net prepared by the invention has the advantages of lightning protection, acid resistance, alkali resistance, no corrosion, high-temperature resistance, low-temperature resistance, no embezzlement value, long service life, excellent impact strength, excellent tensile strength and excellent interlayer shear strength; the product can be made thin and light; no pollution is generated in the production process; and the drawn and extruded polyurethane product is less brittle, so that the assembly can be performed ina conventional manner without cracking and breaking.

Description

technical field [0001] The invention relates to the technical field of anti-glare net production, in particular to a polyurethane anti-glare net and a production process. Background technique [0002] Anti-glare mesh is a variety in the metal mesh industry. Also known as metal mesh, anti-throwing mesh, iron plate mesh, metal expanded mesh, punching plate, etc. As the name implies, it refers to: After the metal sheet is processed by special machinery, it is formed into a mesh-like tension object. It can effectively guarantee the continuity of anti-glare facilities and horizontal visibility, and can also isolate the upper and lower lanes to achieve the purpose of anti-glare and isolation. It is a very effective highway guardrail product. [0003] This kind of net is mostly welded by expanded metal, special-shaped tubes, side ears, and round tubes, and the connecting accessories are fixed with the pillars of hot-dip tubes. Excellent anti-glare performance, mostly used in roa...
