Benefits of technology

This patents describes an improvement method called filtered-based paint (FBC). Unlike traditional paints made from crude oils containing various harmful substances such as benzene), FBC does not require any extra steps like solvent evaporation during manufacturing process. It achieves these technical benefits through its use of naturally occurring raw materials instead of synthetic ones.

Problems solved by technology

Technological Problem addressed in this patents describes how to prepare an effective binder called Tannen Rich Water Base Protained By Natural Refined Lacquard Pineapple Resorcin Bark Extract Suitable Grounding Materials To solve these issues, we found certain chemical substances added during manufacturing processes like mixing together various ingredients before applying paint onto surfaces or forming films. These chemistries improve properties while also being compatible with building environments and requiring longer curable times.

Abstract

The invention provides a natural raw lacquer-based tannin-enriched waterborne primer and a preparation method thereof. The method comprises the following steps that firstly, natural raw lacquer is subjected to low-temperature stirring and filtration pretreatment, then plants rich in tannin and tea polyphenols are decocted, filtered and concentrated, then feeble-acid-ammonium is added, stirring anddissolving are conducted, and a tannin-enriched extract additive is prepared; then, the natural raw lacquer obtained after pretreament, an extender pigment and the prepared tannin-enriched extract additive are mixed, stirred, dispersed and emulsified; finally, edible oil is added, the mixture is stirred to be uniform, and the tannin-enriched waterborne primer of the natural raw lacquer is obtained.
