Plastic float producing process

Abstract

The plastic float producing process is disclosed, and the plastic float as one kind of water floated product consists of casing of polyethylene and stuffing of foamed polystyrene. The production process includes pre-foaming polystyrene beads, maturing the polystyrene beads, filling into the plastic casing, mounting in foaming mold, installing gas inlet and outlet pipes, introducing steam to heat and form, cooling to settle and other steps. The plastic float has low cost, low water absorption and great buoyancy.

Description

technical field [0001] The invention relates to a floating product on water. Background technique [0002] At present, plastic floating bodies have been widely used in the dredging industry as floating products on water. The outer shell is made of polyethylene material, and the interior is filled with polyurethane foam. The outer shell is processed by polyethylene rotational molding. The polyurethane foam includes a combination of polyether and isocyanate , processed by pouring molding process. However, the production cost of this process is high, and the water absorption rate of the filled polyurethane foam is high, which reduces the buoyancy of the plastic floating body. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a new production process of the plastic floating body, which solves the problems of high production cost of the existing plastic floating body, high water absorption rate of filled p...
