Process for the manufacture of a heat-curable, meltable mixture, installation for carrying it out and suitable extruder inlet chamber for use in the latter

摘要: A process for the manufacture of a heat-curable mixture which is preferably solid at room temperature and forms thermoset materials upon curing, example reactive hot-melt adhesive, comprises (A) preparation first premixture (I) by directly introducing (a) meltable resin, least one following components: (b) liquid (c) flexibiliser, (d) an adhesion promoter, (e) plasticiser, liquid, into mixing zone, in components are melted; (B) second (II) heat-activatable hardener following: thixotropic agent, hardening accelerator, additives lending electric conductivity fillers; (C) melt extruding (D) powdered zone downstream introduction melt, has below introduced such amount that content final product from 10 to 50, 20 35% weight, avoiding air inclusions extruded material. An installation carrying out above having special extruder inlet chamber likewise described.
