Wood softening processing fluid for cationic guar gum crafts and preparation method of wood softening processing fluid

Abstract

The invention discloses wood softening processing fluid for cationic guar gum crafts. The wood softening processing fluid is prepared from, by weight, 0.3-0.5 part of cationic guar gum, 5-10 parts of polyethylene 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, 0.3-0.5 part of sodium lignin sulfonate, 1-2 parts of butyl cellosolve, 0.3-0.5 part of casein, 0.5-1 part of dimethicone, 0.3-0.5 part of sodium citrate, 0.01-0.015 part of ethylparaben and 50-60 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 good in uniformity, high in size stability, are not likely to crack or deform, are not likely to mildew, and are 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 cationic guar gum 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 poor, and the...

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 stiffness. 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 drying, and it is easy to rot and mold, so it needs to be further improved
