More-than-once foaming type extrusion molding insulation board production process and equipment thereof

Abstract

The invention discloses a more-than-once foaming type extrusion molding insulation board production process and equipment thereof. The production process comprises the steps of steaming and baking, foaming and traction re-foaming after primary foaming extrusion. The equipment comprises a first extruder, a second extruder, a clamping plate setting machine, a multi-roller tractor, a first steam foaming box, a second steam foaming box, a four-roller tractor and a third steam foaming box which are connected mutually. The more-than-once foaming type extrusion molding insulation board production process and the equipment thereof have the advantages that the size stability of an insulation board is improved substantially, the phenomenon that the insulation board is subjected to contraction deformation due to the fact that the size stability index of the insulation board cannot reach the code standard and the temperature is changed in spring, summer, autumn and winter, and consequently an outer wall insulation board cracks and falls is avoided, and the project quality is ensured.

Description

technical field [0001] The invention relates to an extruded plastic insulation board, in particular to a production process and equipment for a multi-foaming extruded plastic insulation board, which belongs to the field of extruded plastic insulation board production. Background technique [0002] At present, the traditional extruded insulation board is only foamed once in the production process, and the foaming is not uniform, the overall board density is not uniform, and the final product has poor dimensional stability. The dimensional stability of the product seriously exceeds the standard value, and the product used on the outer wall cracks and falls off due to excessive shrinkage and expansion, which reduces the quality of the project and seriously affects personal safety. Contents of the invention [0003] In order to solve the above problems, the present invention designs a production process and equipment for multiple foaming extruded plastic insulation boards, whi...
