Embodiment 1

[0039] A treatment method for improving the staining stability of wood, comprising the steps of:

[0040] (1) Steam explosion treatment:

[0041] Put the wood into the steam explosion tank, and then introduce high-temperature water vapor with a temperature of 102°C into the steam explosion tank, and increase the pressure in the steam explosion tank to 0.35MPa. Unload the steam explosion tank to normal temperature and pressure, and take it out for later use;

[0042] (2) Surface treatment liquid spraying treatment:

[0043] Spray the pre-prepared surface treatment solution evenly on the wood surface treated in step (1), and use it for later use; the surface treatment solution is specifically composed of the following substances in corresponding parts by weight: 10 parts of enhanced attapulgite , 5 parts of sodium hexametaphosphate, 2 parts of calcium stearate, 3 parts of nonylphenol polyoxyethylene ether, 180 parts of deionized water;

[0044] (3) Grinding treatment:

Abstract

The invention discloses a treatment method for improving the dyeing stability of wood. The treatment method comprises the following steps of (1) steam explosion treatment, (2) surface treatment liquidspraying treatment, (3) polishing treatment and (4) microwave treatment. The method is relatively simple in overall process and convenient to apply and popularize, the treated wood is easy to dye, the dyeing stability is obviously improved, and the mechanical strength, the weather resistance and the like of the wood are improved.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a treatment method for improving the dyeing stability of wood. Background technique [0002] Funan County, affiliated to Fuyang City, Anhui Province, is an early inland development area, located in the northwest of Anhui Province, on the north bank of the junction of the upper and middle reaches of the Huaihe River. Funan County is known as "Famous Specialty Products County" and "Natural Resource Bank". It is a major grain production county in the country, the hometown of willow weaving in China, and the only agricultural (forestry) circular economy demonstration pilot county in the country. Funan is the national willow weaving county. Township, willow products are sold abroad. Wood is one of the commonly used raw materials for willow products, but the color of wood itself is single, and most of them need to be dyed to enhance ornamental, practical and value....
