Problems solved by technology

Since the non-metallic fiber reinforcement is added to the horizontal and vertical bars during injection molding, the strength of the horizontal and vertical bars is limited, so that the tensile strength of the entire anchor net is low; and, because the surface of the plastic is relatively smooth, it cannot surface coated concrete

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in Fig. 1 and Fig. 2, the fiber reinforced plastic anchor net of the present invention is solidified by two layers of warp direction fiber reinforcement materials 21, 22 and a weft direction fiber reinforcement material 20 sandwiched between the two layers of warp direction fiber reinforcement materials Composed together, fiber reinforced materials are based on thermoplastics and reinforced with glass fibers or basalt fibers or carbon fibers.

[0020] As shown in Figure 3 and Figure 4, it is a production process flow chart of the glass fiber reinforced plastic anchor net. The lower warp fiber reinforced material 21, the upper warp fiber reinforced material 22 and the weft fiber reinforced material 20 are fiber reinforced materials with polypropylene as the matrix and glass fiber as the reinforced material impregnated, and the fiber reinf...

Abstract

The invention discloses a fibre reinforced plastic anchor net, which is formed by solidifying two layers of meridional fibre reinforced materials and a latitudinal fibre reinforced material between the two layers of meridional fibre reinforced materials. The fibre reinforced materials adopts thermoplastic plastic as base, and glass fibre or basalt fibre or carbon fiber as reinforced material, and the anchor net has high intensity. The invention also discloses a production process for continuously producing the fibre reinforce plastic anchor net, which comprises the following steps: continuous fibres dipped with thermoplastic plastic are uniformly arranged in meridional direction, then the fibres dipped with thermoplastic plastic are uniformly laid on the meridional fibre layer in latitudinal direction, then the continuous fibres dipped with thermoplastic plastic are uniformly laid on the latitudinal fibre layer in latitudinal direction, then the fibre layers are heated by a heating device to solidify the meridional and latitudinal fibre layers, and then the fibre layers are rolled by a roller and the cooled for forming.

Description

technical field [0001] The invention relates to an anchor net and its production process, in particular to a fiber-reinforced plastic anchor net and its production process. Background technique [0002] At present, the anchor net is widely used in the construction of coal mines, tunnels, roads, landslides, and dams. Due to the high cost of metal anchor nets and the fact that they are prone to rust when bare anchors are used, non-metal anchor nets are used in most places. The non-metallic anchor net is composed of horizontal and vertical bars intersecting into a network, and is generally made of plastic injection molding orientation. Although this non-metal anchor net meets the requirements of recovery and explosion protection, its strength is low, and it is difficult to meet the requirements of underground safe production. For this reason, some people add steel wire to the above-mentioned non-metallic anchor net to increase the strength to meet the strength requirements. H...
