PROCESS OF MOULDING POLY(MET)ACRYLIMIDE FOAM PLASTICS AND COMPOSITE PARTS MOULDED THEREOF Russian patent published in 2017 - IPC B32B5/18 B32B27/06 B29K75/00 B29C35/08 B29C43/52 C08J9/36 

FIELD: construction.

SUBSTANCE: advantage of the method is the possibility of a free choice of both the foam plastic material and the cover layer. In particular, the coating layers, the processing temperature of which differs significantly from the processing temperature of the core material, can also be processed by said method. In addition, a method is described, in the second implementation version of which the internal structures of the foam plastics can be partially compacted. The third method implementation version allows, by means of welding at least two foam blanks, to produce a hollow body with especially high-quality joints. The method can be carried out both in the presence and in the absence of the cover layers. In addition, the process described is particularly suitable for the processing of foam plastic materials by means of vacuum moulding.

EFFECT: invention provides a method by which fast and easy moulding of rigid plastic foams can be carried out without damaging their structure, or they can be processed into composite materials together with coating layers, in particular thermoplastic synthetic materials.
