Problems solved by technology

[0004] Because masson pine wood is soft and has strong water absorption, it is easy to cause problems such as perishability, insects, deformation, and poor dimensional stability; Increased cracking
CN201811553567.6, a Chinese invention disclosed in a hydrophobic wood and its preparation method, involves infiltrating molten polypropylene wax and nano-SiO2 into the wood, which can improve the surface hydrophobicity of masson pine to a certain extent, but will cause wood The roughness becomes larger, and the internal fiber structure is damaged and broken, which affects its service life and processing performance

Embodiment 1

[0019] A processing method for improving the surface hydrophobicity of masson pine wood, which is specifically realized by the following process steps:

[0020] 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. The loose workpiece is placed in a heat treatment box, completely soaked in the hydrophobic treatment agent, heated to 40°C at a rate of 0.8°C / min, sealed and kept for 60 minutes, continued to heat up to 50°C, sealed and kept for 30 minutes, and finally heated to 70°C. Seal and keep warm for 15 minutes, after natural cooling, take out the workpiece, put it in a constant temperature and humidity environment, the temperature is 24°C, the relative humidity is 63°C, and it can be air-dried for 5 hours.

Abstract

The invention relates to a processing method for improving the surface hydrophobicity of masson pine wood. The treatment and modification of masson pine wood is carried out. Compared with the treatment of masson pine wood, the hydrophobic treatment containing hydrophobic dispersed particles is used Under intermittent temperature rise, the carrier liquid and the loaded particles work together to increase the hydrophobic effect of the plate by 30-40%, and the surface has better hydrophobic performance, because the treatment agent containing organosilane can form a gap between the particles and the particles. The covalent bond makes the interior of the wood always have a high hydrophobicity, and can prevent the wood from becoming hydrophobic under the action of external forces such as light and friction. The stability after processing is also improved, and the production process is easy to control. , to solve the unfavorable problems in the processing and utilization of masson pine wood, the hydrophobicity is significantly enhanced, and its application range is broadened.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a processing method for improving the surface hydrophobicity of masson pine wood. 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 wate...
