Wood softening processing fluid for mould-proof and insect-proof crafts and preparation method of wood softening processing fluid

Abstract

The invention discloses wood softening processing fluid for mould-proof and insect-proof crafts. The wood softening processing fluid is prepared from, by weight, 5-10 parts of poly(ethylene glycol), 4-6 parts of glacial acetic acid, 0.5-1 part of alum, 2-4 parts of hydrogen peroxide with the mass fraction ranging from 20% to 30%, 1-2 parts of polyvinyl alcohol, 2-4 parts of folium artemisiae argyi, 2-4 parts of cortex meliae, 1-1.5 parts of leaves of bunge pricklyash, 0.3-0.5 part of sodium dodecylbenzene sulfonate, 0.1-0.15 part of carboxymethyl chitosan, 0.1-0.15 part of tea saponin, 0.1-0.15 part of tall oil, 0.01-0.015 part of ethylparaben and 60-80 parts of water. The wood softening processing fluid is good in softening processing performance, wood is high in strength and tenacity and is not likely to rebound, subsequent processing is not influenced, dried and formed finished products are high in size stability, are not likely to crack or deform, and are good in mould-proof and insect-proof effect, wide in application range, capable of saving energy and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chemical treatment agents, in particular to a mildew-proof and insect-proof handicraft wood softening treatment liquid and a preparation method thereof. Background technique [0002] In the processing of wooden handicrafts, softening the wood as raw material is a very important step. Under normal conditions, wood is a material that lacks plasticity. By softening the wood, it can show temporary plasticity. At this time, the wood can be subjected to plastic processing such as bending, compression, and embossing. After drying, it can restore its original rigidity and strength, realize the permanent plastic deformation of wood, and make the handicrafts have high strength, beautiful shape and good decorative performance. Common softening methods include boiling, high temperature and high pressure steam treatment and chemical agent treatment. The dimensional stability of the wood treated by these methods is p...

AI Technical Summary

Problems solved by technology

The dimensional stability of the wood treated by these methods is poor, and the processing performance and use performance will also be adversely affected

Patent CN201510993437 uses glacial acetic acid, polyethylene glycol and anionic surfactants as the main ingredients to prepare a wood softener to make the treated wood have good strength and rigidity. Although this softener improves the processing performance of the softened wood to a certain extent and molding stability, but there is no obvious improvement on the defects that the wood is easy to crack and deform after softening, and is easy to rot and mold, so it needs to be further improved
