Problems solved by technology

[0003] What the emulsion of existing water-based wood coating adopts is synthetic emulsion, and this synthetic emulsion is extracted from petroleum, and the water-based wood coating made by this synthetic emulsion has good adhesion, paint film is full, has certain hardness, but because synthetic emulsion is from The emulsion extracted from petroleum is a kind of consumption for the limited petroleum resources on the earth. From the perspective of saving petroleum resources, we urgently need an emulsion, which comes from renewable resources, and the water-based woodware prepared from this emulsion Coatings perform as well as waterborne wood coatings made with synthetic emulsions

Abstract

The invention relates to a natural emulsion. The natural emulsion comprises the compositions in percent by weight: 1-2% of an emulsifier, 40-70% of plant oil, 5-30% of natural resin, 5-30% of an active monomer polymer and 8-15% of water. The invention also relates to aqueous woodenware paint prepared from the natural emulsion, and the aqueous woodenware paint is characterized by comprising the compositions in percent by weight: 1-3% of water, 81-88% of the natural emulsion, 3-10% of a cosolvent and 0-10% of a pigment or filling material, and preferably also comprising 0.7-1.2% of an anti-foaming agent, 0.3-0.6% of a wetting agent, 0.2-0.5% of a slip agent, 0.5-1% of a levelling agent and 2-4% of a hardening agent. Compared with conventional aqueous paint, the natural aqueous woodenware paint provided by the invention employs the renewable natural emulsion as the emulsion, so that petroleum resource is saved; and also, plant oil and natural resin in the natural emulsion in the paint are biodegradable under the effect of lipase, so that the waste paint can be biodegraded by employing lipase, and thus the paint has no pollution to environment and is green and environment-friendly.

Description
