Example Embodiment

[0011] As shown in the figure, a high-strength safety net includes two base layers 1 interwoven with glass fiber yarns. The center of the base layer 1 is provided with an iron ring 2, and an abrasive layer 4 is adhered to the base layer 1. With mesh 3.

[0012] The base layer 1 is a cymbal type.

[0013] The abrasive layer 4 is a corundum abrasive layer or a silicon carbide abrasive layer.

[0014] The abrasive layer 4 is an abrasive layer with an abrasive grain size of 24 to 120 mesh.

[0015] The preparation process of the matrix in the present invention is as follows: the high-strength glass fiber filament is surface-active treated, interwoven into a 6-16 mesh net-like body, cut into a disc shape with a diameter of φ100-180mm, and immersed in a phenolic modified epoxy resin chemical In the adhesive solution, after the glue is quantified by the high-speed centrifuge, the abrasives of various properties are bonded as the grinding layer, and then pressed into a cymbal shape, and drie...

Abstract

The invention discloses a high-strength safety net. The high-strength safety net comprises two base body layers formed by interweaving of fiber glass filaments. An iron ring is arranged at the centers of the base body layers. Grinding material layers are adhered to the base body layers. Meshes are formed in each base body layer. The high-strength safety net has the advantages that a base body of the safety net is formed by combination of the two base body layers formed by interweaving of the fiber glass filaments, and high uniformity in technological production process is achieved; grinding materials are adhered to the surfaces of the base body layers and enter a middle layer between the two base body layers during compression molding, so that the grinding materials and the meshed fiber glass base body are bound evenly, and binding force is high; impact force resistance and turning strength of the net are improved greatly after solidification, safety turning line speed of the net is high, and reliability exceeds requirements of internal turning test standards.

Description

technical field [0001] The invention relates to a safety net, in particular to a high-strength safety net. Background technique [0002] Safety nets are used to prevent people and objects from falling, or to avoid and reduce falling and object damage. The safety net is generally composed of a net body, side ropes, tethers and other components. Safety nets are widely used in various construction sites, especially high-rise buildings. They can be fully enclosed and can effectively prevent personal and object falling injuries, prevent fires caused by welding sparks, reduce noise and dust pollution, achieve civilized construction, and protect the environment. , the effect of beautifying the city. [0003] Existing safety net is made of net body, side rope, tether and tendon rope. The net body is woven from net ropes and has a rhombus or square mesh. The distance between two adjacent knots of the braid is called the mesh size; the net rope on the edge of the net body is calle...
