METHOD OF PRODUCING MULTILAYER COMPONENTS AND VULCANISER TO THIS END Russian patent published in 2011 - IPC B32B3/12 B32B37/00 

FIELD: process engineering.

SUBSTANCE: invention relates to method of producing multilayer components with coat layers made from thermoset. Invention covers the method of producing multilayer components comprising central layer with open structure and coat layers 1, 3 applied on both surfaces of central layer. Note here that coat layers are made from thermoset, while multilayer component is vulcanised at pressure in sealed device, e.g. vulcaniser or autoclave. Note also that filling gas, e.g. nitrogen or air, is fed into central layer till, at least, partial hardening of coat layers. Not also that filling gas pressure is selected not to exceed closed device operating pressure to prevent origination of recesses on coat surface. Note also that filling air pressure is varied by control device subject to degree of coat layer hardening, while material viscosity is measured by said control device to vary pressure of filling gas. Invention covers also vulcaniser consisting of two parts 4, 5 with heater-controlled temperature, and tight housing 6 accommodating central layer and, at least, two coat layers 1, 3 produced from thermoset. This vulcaniser serves to produce multilayer coat under pressure. Housing 6 comprises, at least, one connection device 8, 9, 10 for feed and/or discharge filling gas into central layer 2, or from central layer 2 for, at least, partial preventing origination of recesses on the surface of layers 1,3 during vulcanisation. Note here that filling gas pressure varies subject to viscosity of coat layer material.

EFFECT: multilayer components with optimum characteristics of their surface.
