[0044] The invention provides a method for preparing a non-slip material based on a fiber array comprising the following steps:
[0045] The first step, fiber pretreatment: the fiber filaments are cut into a certain length of chopped fibers by a fiber cutter, and the chopped fibers are sieved by a mechanical vibrating screen for 2 hours. Chopped fibers pass through screens of different meshes, and fibers with similar lengths stay in the same mesh. After sieving, the chopped fibers have high consistency in length and good dispersion. The mesh numbers of the sieves are respectively: 50 mesh, 100 mesh, 200 mesh, 300 mesh and 400 mesh.
[0046] The second step is to apply adhesive glue: use ethanol or acetone solvent to clean the surface of the substrate, and evenly coat the adhesive glue with a thickness of not less than 100 μm. For flat substrates, the adhesive can be coated with a wire rod or a film applicator; for special-shaped substrates, the adhesive can be evenly sprayed ...

[0057] The preparation method of the anti-slip material of the glass fiber array epoxy substrate of the present embodiment is as follows:
[0058] (1) Place the glass fibers with a length of 0.5 mm in a mechanical vibrating sieve and sieve for 2 hours. The meshes of the screens are: 50 mesh, 100 mesh, 200 mesh, 300 mesh and 400 mesh;
[0059] (2) Take out 1g of the fiber sample on the 100-mesh sieve and evenly disperse it on the metal plate under the high-voltage electrostatic device; use double-sided adhesive tape to attach the epoxy resin substrate to the surface of the upper metal plate, and clean it with ethanol and acetone respectively Surface: weigh 1g of epoxy adhesive, and use a wire rod to evenly coat the surface of the substrate, with a wet film thickness of 200μm;
[0060] (3) Install an electrostatic flocking device, adjust the distance between the plates to 10cm, and place a nylon screen frame in parallel in the middle of the plates, with a screen mesh of 100 mesh...
