Abstract
A shape-preserving fire-prevention pipe consists of a frame layer and a lining layer, wherein the lining layer is tubular; the frame layer is fixedly coated on the periphery of the lining layer and is formed by weaving fibers; and the lining layer is formed by co-extruding and co-molding a thin-walled polyurethane adhesive layer and a polyurethane waterproof layer. A method for manufacturing the shape-preserving fire-prevention pipe comprises the following steps: manufacturing the lining layer and the frame layer, wherein the frame layer is formed by weaving warps and wefts; inserting the lining layer into the frame layer; injecting compressed air into the lining layer; uniformly combining the lining layer and the inner wall of the frame layer; and injecting vapor into the lining layer for heating and pressurizing to bond the frame layer and the lining layer, wherein the thickness ratio of the thin-walled polyurethane adhesive layer to the polyurethane waterproof layer is 1:2-1:3. The shape-preserving fire-prevention pipe is flexibly deformable and has the minimum radius of curvature of 10 centimeters, anti-hydrolysis ability, acid-alkali resistance and an aging lifetime of more than 8 years; and when in use, the pipe can spray water quickly and does not need spreading and straightening. The frame layer supports the lining layer, so the bursting pressure is high, the weight is light, and further the pipe is convenient to transport and use.
