(1)
A method for producing a recycled foamed resin block having a thickness of 400 mm or more by reusing a foamed resin molded article, comprising: a step of cutting the foamed resin molded article into square pieces; A step of filling the mixture with the pre-expanded particles to be used, and a step of steam-heating the inside of the mold to form the mixture. A method for producing a reclaimed foamed resin block, comprising filling a mold and, after the filling is completed, setting the thickness of the mold to a molding thickness and performing steam heating.
(2)
The method for producing a regenerated foamed resin block according to claim 1, wherein after the mixture is filled from a mold filling port, unused pre-expanded particles are filled near the filling port.
(3)
A regenerated foamed resin obtained by molding a mixture of a rectangular piece obtained by cutting a foamed resin molded body to a size of 10 to 30 mm on one side and unused pre-expanded particles by steam heating in a mold. block.
(4)
The recycled foam resin block according to claim 3, wherein the mixture ratio of the square pieces of the mixture is 60% or less.
Claim 5.
The regenerated foamed resin block according to claim 3 or 4, wherein a density difference between the density of the square pieces and the density of unused pre-expanded particles is within 10% of the density of the square pieces. .
