Traditional sheet piles can be divided into wood sheet piles, steel sheet piles, reinforced concrete sheet piles, etc. according to their materials. These materials all have certain defects. Wood sheet piles have low strength and are easily degraded by the microbial attack; Compared with traditional sheet piles, PVC sheet piles have many advantages such as corrosion resistance, lightweight, high strength, low cost, suitability for large-scale production, and easy maintenance; PVC sheet piles are expected to be used in embankment reinforcement, pond water retention, and municipal engineering and other fields to replace traditional sheet piles.

As one of the five general-purpose plastics, polyvinyl chloride (PVC) is second only to polyethylene in output; PVC resin is produced by the polymerization of liquid vinyl chloride monomer (vcm) through suspension, emulsion, bulk, or solution processes become. PVC has been widely used in daily life in industry and agriculture due to its cheap, unique flame retardant, insulation, wear-resistant, and other excellent mechanical properties; Under the action of external factors such as machinery, PVC is prone to aging and degradation, resulting in discoloration, embrittlement, cracking, and decline in mechanical properties, and eventually loses its use value. The defect in the structure of PVC itself is the internal cause of its easy aging; During the application process, it is easily corroded by seawater, and there are problems such as aging degradation and unstable mechanical properties.

pvc sheet pile, its preparation raw materials include polyvinyl chloride, stabilizer, chlorinated polyethylene, modified polyacrylic resin, and other auxiliary additives; wherein, the preparation raw materials of the modified polyacrylic resin include methyl methacrylate and butyl acrylate For esters, r contains at least one double bond.

Among them, in parts by weight, the preparation raw materials include 70-120 parts of polyvinyl chloride, 5-15 parts of stabilizer, 50-80 parts of chlorinated polyethylene, 30-60 parts of modified polyacrylic resin, and 20-50 parts of other additives. agent additives.
Wherein, the molar ratio of methyl methacrylate and butyl acrylate is 1:(2-6):(1-3).
Wherein, the number of carbon atoms in r is 3-12.
Wherein, the structure of r is selected from any one or a combination of more.
Wherein, the stabilizer is selected from any one or a combination of hindered amine stabilizers, benzophenone stabilizers, and salicylic acid stabilizers.
Wherein, the stabilizer is a hindered amine stabilizer, and the stabilizer is a light stabilizer 770 and/or light stabilizer 123.
Wherein, other additives include a plasticizer, calcium powder, and titanium dioxide; wherein, the weight ratio of the plasticizer, calcium powder,  and titanium dioxide is 1:(0.5-1.5):(0.5-1.5).
Among them, it includes three steps melting, extrusion molding, and cooling.
Among them, the melting process is to place polyvinyl chloride, stabilizer, 1/2 of the total weight of modified polymethyl acrylate, chlorinated polyethylene, other additives, and the remaining modified polymethyl acrylate in the melting equipment, blending and heating.
