Abstract

The invention provides the raw lacquer made by refined raw lacquer, inorganic nano material, loading-pigment, coupling agent, deflocculating agent, curing agent, drier and auxiliary agent. The invention also provides preparing method. The said raw lacquer possesses good antiweatherability, ageing resistance, resistance to ultraviolet radiation, abrasive resistance and adhesive force. So it is possible to use raw lacquer in outdoor.

Description

technical field [0001] The invention relates to a raw lacquer, in particular to a raw lacquer modified by inorganic nanometer materials, and belongs to the field of coatings. Background technique [0002] The decorative effect of paint on the surface of objects is well known. It can increase the color and luster of the surface of the object, and can also modify and smooth the roughness and defects of the surface of the object, improve the appearance quality, increase the value of the commodity, and prolong the service life of the object. Natural lacquer is one of the native products of our country. It comes from virgin forests and natural lacquer trees. Natural lacquer is the natural lacquer sap artificially cut from lacquer trees. The natural lacquer sap mainly contains polymer urushiol, laccase, gum components such as quality and moisture. Natural raw lacquer has the reputation of "three treasures" in my country (cutting lacquer from trees, spinning silk from silkworms, a...
