Description

Manufacturing method of black persimmon wood drawing board

Technical Field

The invention relates to a method for manufacturing a black persimmon wood drawing board.

Background

The wooden board painting is one of Chinese paintings, the traditional habit of drawing on wooden materials such as wooden boards, wooden slips and the like exists in ancient China, and modern artists combine natural lines of wooden grains to perform artistic processing such as carving, spraying, manual drawing and the like, so that the artistic enjoyment on spirit and vision is brought to people.

Black persimmon Ziricote, Ciricote, reading as "clitoris of west science", science name: cordia docandra, chinese name: twelve stamen raglan wood belongs to the Boraginaceae, because the color of the wood core material is from middle to dark brown, some sample plates have green gray color, black dark stripes are distributed along the growth wheel in a crossed way, spider-web patterns and landscape patterns (landscapes) of the wood core material are often particularly remarkable, the radial section (quartz awn) of the wood core material has obvious wood ray stripes, the textures are staggered slightly, the natural glossiness is good, and the wood core material is rotten-resistant, so that the wood core material is recognized by the art, some of the wood core material is used as an artwork, a playing piece and some of the wood core material is tried to be made into a forming plate to be drawn. But the application is limited because the end face and the surface of the wood are easy to crack and other defects in the drying process of the wood.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the natural wood black persimmon wood is used as a raw material, and a processing technology with improved technology is adopted, so that the black persimmon wood drawing board is light, not easy to crack, low in cost and high in quality.

In order to solve the problems, the invention adopts the technical scheme that: after cutting and drying, the board is sprayed with a mixed solution of Potassium permanganate (Potassium permanganate) solution and 3% hydrogen peroxide (hydrogen peroxide) solution in a ratio of 1: 1000, inorganic impurities (such as iron, lead and the like) are removed by utilizing the strong oxidizing property of the mixed solution to bleach and easily draw pictures, so that the dehydration, protein solidification and wood grain tightening of the board surface are promoted, the cracking degree is greatly reduced, and the wood grain of the manufactured board is deep, astringent and jerky and has more active and rhythmic beauty.

In the technical scheme of the black persimmon wood drawing board, the manufacturing method comprises the following steps:

A. selecting materials: selecting black persimmon wood as a wood blank, and putting the wood blank into a water pool for cooking;

B. processing: rotary cutting or slicing the black persimmon wood raw material by using a cutter, and cutting the black persimmon wood raw material into wood sheets such as veneers, battens and wood boards according to the specific required size for later use, wherein the processed wood sheets are smooth, neat and provided with obvious textures;

C. bleaching: carrying out specific chemical treatment on the processed wood slice, bleaching with a strong oxidant, and then cleaning the chemically treated material with clear water;

D. drying: putting the wood slices into a dryer for drying treatment, so that the water content of the wood slices is less than 10%;

E. compacting: and G, compacting the crude drawing paper product obtained in the step G by using a tablet press at normal temperature, and drying and forming:

F. unloading from the press, and placing in a ventilated drying place or a drying room for drying;

G. coarse grinding: a wood chip grinding machine is used for carrying out coarse grinding treatment on one surface of the wood slice;

H. performing corrosion-resistant, discoloration-resistant and waterproof treatment;

and f, fine grinding for picture making: selecting a wood chip polisher to perform fine grinding treatment on the picture;

J. the painting pigment is prepared by mixing natural plant with 1-5% of natural raw lacquer.

The strong oxidant is mixed solution of potassium permanganate solution (volume ratio) of 1: 1000 and hydrogen peroxide solution (volume ratio) of 3% for spraying.

The raw materials are placed into a water pool and boiled for 24-28 hours by using hot water of 85-100 degrees.

The drying temperature is 7-10 degrees.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:

1. provides a wooden painting and calligraphy material which is not easy to crack and deform.

2. Provides a material for carving, spraying, manual painting or printing.

3. The method for making the black persimmon wood drawing board can be used for large-scale production, and various natural logs with different shapes and textures and vivid and rare can be changed according to the design of a designer.

4. The painting pigment is prepared by adding 1-5% of natural raw lacquer in the blending process except for selected natural plant elements, and by utilizing macromolecular urushiol, laccase, gum and the like contained in lacquer liquid and water and the like, the surface of the painting is bright and glaring, good in fullness, more resistant to high temperature, oxidation, wear and durability.

Detailed Description

Several embodiments of the invention are provided below.

Firstly, selecting black persimmon wood as a raw material, putting the raw material into a water pool, and steaming the raw material for 24-28 hours by using hot water of 85-100 degrees.

Rotary cutting or slicing the black persimmon wood raw material by using a cutter, and cutting the black persimmon wood raw material into wood sheets such as veneers, battens and wood boards according to the specific required size for later use, wherein the processed wood sheets are smooth, neat and provided with obvious textures; then cutting a veneer with the length of 2.6m, the width of 120cm and the thickness of 20mm according to the specific size of the die for later use; the processed veneer is chemically treated with a strong oxidant. Spraying a mixed solution of potassium permanganate solution and 3% hydrogen peroxide solution with the ratio of 1: 1000 by using a strong oxidant, and then cleaning the chemically treated veneer by using clear water; the veneer after chemical treatment must be dried as soon as possible to avoid mildewing and blackening, and the veneer is treated by a drier without being dyed by a drier mesh belt, and is clamped and dried by a mesh clamp. The dried veneer with the drying temperature of 7 ℃ is subjected to strict color difference selection control, and the veneer with black, knots and holes is repaired and finished by professional staff; profiling a professional die: pressing for 180 minutes by a press at 160T to form the product. Selecting a wood chip grinding machine with a 120-mesh grinding wheel to perform coarse grinding treatment on one surface of the wood slice; performing corrosion-resistant, discoloration-resistant and waterproof treatment; fine grinding to make pictures: and selecting a wood chip polisher to perform fine grinding treatment on the picture.

After the processing, the black persimmon wood drawing board can be obtained.
