摘要:
Aspects of the present invention include interior vehicle trim panel having a sprayed expanded polyurethane layer and method of making same. In at least one embodiment, the method of making the vehicle interior trim panel comprises providing a skin layer on a spray tool, providing a source of polyol, and providing a source of isocyanate, wherein at least one of the sources contains a nucleated component. The method of this embodiment further comprises combining polyol and isocyanate from the respective sources to form expandable polyurethane reactive component, spraying the expandable polyurethane reactive component onto the skin layer to form a resilient layer, and securing a rigid substrate to the resilient layer to form the vehicle interior trim part.
摘要:
An apparatus for spraying polyurethane to form a skin on a mold. Polyurethane forming constituents are provided from a plurality of separate supply sources to separate recirculating fluid circuits. A mix head receives polyurethane constituents from the fluid circuits and mixes them to form a polyurethane mixture. A hydraulically operated valve controls the flow of the polyurethane constituents. The valve has a first position in which the polyurethane components are permitted to flow into the chamber of the mix head. The polyurethane mixture is then dispensed through a spray nozzle assembly. When the valve is in a second position, the polyurethane constituents are recirculated through the fluid circuits. A liquid solvent may be injected into the mix head under pressure to purge the mixture from the mix head and spray nozzle assembly in the second position.

An apparatus for supplying differently colored polyurethane forming materials includes a source of isocyanate, a source of polyol, multiple colorant sources for supplying multiple colorants, and multiple premix chambers that are each connected to a respective colorant source and one of the source of isocyanate and the source of polyol. Each premix chamber has a mixing element for mixing a respective colorant and one of isocyanate and polyol to form a selectively colored material. The apparatus further includes a spray head in communication with the premix chambers and the other of the source of isocyanate and the source of poloyl, and a valve assembly disposed between the spray head and the premix chambers for selectively introducing selectively colored material from one of the premix chambers and the other of isocyanate and polyol to the spray head.

A method for forming a low density polyurethane skin for automobile interior applications is provided. The method of the invention comprises spraying an expandable polyurethane composition over a mold cavity surface or a mold cavity surface pre-coated with a primer polyurethane layer to form the low density polyurethane skin. A sufficient amount of the expandable polyurethane composition is sprayed so that the low density polyurethane skin has a thickness from about 0.5 to about 3 mils. The expandable polyurethane composition includes an isocyanate, a polyol, a blowing agent, an optional catalyst, and an optional surfactant. An article made by the method of the invention is also disclosed.
摘要:
The present invention relates a vehicle interior trim panel. In at least one embodiment, the panel may be made by providing a spray mold having a mold surface, spraying colored polyurethane material proximate the surface of the tool to form a colored polyurethane skin layer, and spraying expandable polyurethane material onto the skin layer to form a resilient layer on the colored polyurethane skin layer. The colored polyurethane skin layer and the resilient layer form a colored composite skin which can be removed from the tool and secured to a substrate to form a vehicle interior trim panel.

In at least one embodiment, the present invention relates to a method and system for making a composite polyurethane skin. In at least one embodiment, the method comprises providing a source of liquid polyol, providing a source of liquid isocyanate, providing a source of liquid low density foaming agent comprising blowing agent and low fogging surfactant, providing a spray mold tool having a mold surface, and providing a spraying device for spraying liquid material at the spray mold tool. The method further comprises, in at least one embodiment, directing polyol and isocyanate to the spraying device to form a polyurethane composition, spraying the polyurethane composition towards the spray mold tool to form a polyurethane skin layer on the spray mold tool, directing polyol, isocyanate and low density foaming agent to the spraying device to form an expandable polyurethane composition, and spraying the expandable polyurethane composition onto the skin layer to form a resilient expandable polyurethane layer on the skin.
