Embodiment 1

[0016] A kind of masson pine wood dyeing pretreatment method, it is specifically realized by the following process steps:

[0017] The masson pine wood in Henan area is used as the material. After the masson pine wood is cut according to the processing and production requirements, the surface of the masson pine wood is polished, and the surface debris is blown off with compressed air to obtain a finished workpiece. Place the loose workpiece in a heat treatment box, soak it completely in the treatment agent, raise the temperature to 70°C at a rate of 2.3°C / min, seal and keep it for 20 minutes, continue to heat up to 80°C, keep it sealed for 40 minutes, and finally raise the temperature to 90°C, seal it Keep warm for 1.0 hour, after natural cooling, take out the workpiece, put it in a constant temperature and humidity environment, the temperature is 22°C, the relative humidity is 65°C, and air-dry for 3 hours.

[0018] As preferably, the preparation method of described treatment...

Abstract

The invention relates to a masson pine wood dyeing pretreatment method which comprises the following steps: treating and modifying masson pine wood, enhancing the adsorption capacity of an amorphous region in the wood by using a treating agent with strong adsorption and permeation functions under intermittent heating, promoting the reaction with dyes, generating fiber dye covalent bonds. The intermolecular attraction between the dye and the wood is greatly improved, the problems of color development system change, color fading and the like caused by the fact that the wood absorbs light energyto form an excited state under the action of light can be prevented, the stability after dyeing is also improved, the production process is easy to control, and the problems of low dye uptake and insufficient color fastness exist when the dye is used for dyeing masson pines can be solved.

Description

technical field [0001] The invention relates to the technical field of wood dyeing and processing, in particular to a pre-treatment method for masson pine wood dyeing. Background technique [0002] Masson pine is widely distributed, from Henan and southern Shandong in the north, to Guangdong, Guangxi, Hunan (Cili County), and Taiwan in the south, from the coast in the east, to central Sichuan and Guizhou in the west, and spread all over South China. Generally, it is distributed below the altitude of 600-700m in the lower reaches of the Yangtze River, above about 1200m in the middle reaches, and below about 1500m in the upper reaches. It is the main timber tree species in southern China. High economic value. [0003] Masson pine is not resistant to decay. The difference between heartwood and sapwood is not obvious, light yellowish brown, long longitudinal fissures, long flaky peeling; wood texture is straight, thick structure; resinous, resistant to water and humidity.
