Embodiment approach 1

[0011] The first step is to smooth the surface of the blank that needs natural relief treatment; the second step is to coat the ferric chloride saturated solution on the flat surface of the processed blank; the third step is to use a hot press at a pressure of 0.5 Under the conditions of MPa and temperature of 140° C., the coated billet is hot-pressed for 180 seconds; in the fourth step, the hot-pressed billet is naturally dried and cooled.

[0012] Using the natural embossing method of the natural wood surface of the above-mentioned technical scheme, the ferric ions in the ferric chloride solution chemically react with the tannins in the wood surface to realize the staining of the wood surface. The density of the material inside the wheel is different, and when it is corroded, the depth is different, and the wood grain of the annual ring appears, so that the wood surface presents a natural relief effect, which can achieve the effect of antique wood, especially for wood density...

Embodiment approach 2

[0014] The first step is to smooth the surface of the blank that needs natural relief treatment; the second step is to coat the iron sulfate saturated solution on the flat surface of the processed blank; the third step is to use a hot press at a pressure of 4MPa, The coated billet is hot-pressed at a temperature of 80° C. for 80 seconds; in the fourth step, the hot-pressed billet is naturally dried and cooled.

Embodiment approach 3

[0016] The first step is to smooth the surface of the blank that needs natural relief treatment; the second step is to coat the saturated solution of ferric nitrate on the flat surface of the processed blank; the third step is to use a hot press at a pressure of 3MPa, The coated billet is hot-pressed at a temperature of 120° C. for 120 seconds; in the fourth step, the hot-pressed billet is naturally dried and cooled.

Abstract

A method for making the surface of natural wood material have relief effect includes such steps as smoothing the wooden surface, coating the saturated solution of 3-valence Fe salt (iron chloride, iron sulfate or iron nitrate), hot pressing at 80-140 deg.C under 0.5-4 MPa for 80-180 s, and natural cooling and drying.

Description

technical field [0001] The invention relates to a method for natural embossing treatment on the surface of natural wood by using chemicals. Background technique [0002] In furniture and some other wooden products, for the sake of aesthetics, the wood surface is often treated with natural relief effect. At present, the method of mechanical surface grinding is used to process the wood surface to achieve natural relief effect. But the method processing difficulty of this timber surface natural embossing is big, and production efficiency is low, and production cost is high, and quality is difficult to guarantee. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for natural embossing treatment of natural wood surface with simple processing, low cost, reliable performance and high production efficiency. [0004] In order to solve the above-mentioned technical problems, t...
