Synthesis device and process for novel aromatic ultraviolet (UV) water-borne polyurethane

Abstract

The invention discloses a synthesis device and a process for novel aromatic ultraviolet (UV) water-borne polyurethane. The synthesis device comprises a multiple trimethylolpropane derivative acrylic ester synthesis device and a water-borne chain extender preparation and UV water-borne polyurethane synthesis device, the trimethylolpropane derivative acrylic ester synthesis device comprises an esterification device, a water washing device and a distilling device, the bottom of the esterification device is connected with the upper portion of the water washing device through a pipeline, the lower portion of the water washing device is connected with the upper portion of the distilling device through the pipeline, the UV water-borne polyurethane synthesis device comprises a first vacuum pump, a first reacting kettle and a deionized water tank, one side of the upper portion of the first reacting kettle is connected with the deionized water tank through the pipeline, and the other side of the upper portion of the first reacting kettle is connected with the first vacuum pump through the pipeline. The synthesized UV water-borne polyurethane has the advantages that the emulsion stability is good, the film hardness can meet requirements of wood floor primer, and the novel UV water-borne resin with an excellent pigment wettability is suitable for UV water-borne inks.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a synthesis device and process of novel aromatic UV water-based polyurethane. Background technique [0002] UV water-based polyurethane occupies a dominant position in the application industry of wood floor primer in China. The UV water-based polyurethane produced by domestic manufacturers has no advantages in performance and price. Now the UV water-based polyurethane on the market is mainly polyurethane resin synthesized by HDI Mainly, not only the production cost is high, but also the hardness of the synthetic UV water-based polyurethane film cannot meet the requirements of the wood floor primer. Some manufacturers have also introduced aliphatic polyurethanes. It plays a very good role in performance, but the price is relatively high, resulting in high production costs. At the same time, because the invention can be applied to the ink field, it is environmentally f...
