The invention relates to a method for homogenously incorporating filler into a self-adhesive compound, in particular a thermally crosslinkable self-adhesive compound, based on non-thermoplastic elastomer in a continuously working unit with a filling part and a compounding part. The self-adhesive compound contains at least one solid component, at least one liquid component, and at least one filler, and the method has the following steps: (a) feeding at least part of the at least one solid component, such as the non-thermoplastic elastomer in particular, and optionally part of the at least one liquid component to the filling part; (b) transferring the components of step (a) from the filling part to the compounding part; (c) optionally adding additional solid components or additional parts of the solid components to the compounding part; (d) adding the at least one liquid component to the compounding part if the liquid component was not already added to the filling part in step (a); (e) producing a homogenous self-adhesive compound in the compounding part; and (f) discharging the self-adhesive compound. The invention is characterized in that at least part of the at least one filler is pre-dispersed into at least one dispersion liquid in a separate unit and the dispersion obtained in this manner is added to the compounding part. The method prevents high sheering or frictional energies while introducing the filler into the compounding part of the continuously working unit and thus allows the use of temperature-sensitive components, such as temperature-sensitive chemical crosslinking agents in particular. 1.

Mixing and dispensing device

Номер: US20150122837A1
Автор: Melanie R. Werner, Paul J. Mulhauser
Принадлежит: MOUSE TRAP DESIGN LLC

A device for mixing and dispensing fluids has first and second walls that form a chamber connected to a nozzle. Inlets each configured to receive one fluid are arranged in the first wall. Proximate edges of the inlets are an equal distance from a central point on the first wall. A seal having top and bottom surfaces and a center through hole is secured in the chamber. The center hole is substantially aligned with the central point. A surface area of the top surface is greater than a sum of the sectional areas of the inlets. A dispensing pump moves the seal between a sealed position in which the bottom surface seals the inlets and an open position in which the bottom surface is spaced away from the inlets to open the inlets to draw the fluids into the chamber to form the mixture for dispensing through the nozzle.
