Wood softening treatment fluid for pullulan artware and preparation method for wood softening treatment fluid

Abstract

The invention discloses a wood softening treatment fluid for pullulan artware. The wood softening treatment fluid is prepared from the following raw materials in parts by weight: 0.3-0.5 part of pullulan, 0.5-1 part of sodium alginate, 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 mass fraction being 20-30%, 1-2 parts of polyvinyl alcohol, 0.5-1 part of xylitol, 0.3-0.5 part of lauryl polyoxyethylene, 0.5-1 part of sodium gluconate, 0.01-0.015 part of ethylparaben and 50-60 parts of water. The wood softening treatment fluid disclosed by the invention is good in softening and processing performance; wood is high in strength and toughness, and is not liable to rebound, and follow-up treatment is not affected; and a dried and molded product is high in dimension stability, is not liable to crack and deform, is not liable to generate mildew and rot; and moreover, the wood softening treatment fluid is wide in scope of application, is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of chemical treatment agents, in particular to a pullulan polysaccharide handicraft wood softening treatment liquid and a preparation method thereof. Background technique [0002] In the processing of wooden handicrafts, softening the wood as the raw material is a very important step. Under normal conditions, wood is a material lacking 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, embossing, etc., and then under the condition of deformation After drying, the original stiffness and strength are restored, and the permanent plastic deformation of the wood is realized, so that the handicrafts produced have high strength, beautiful shape and good decorative performance. Common softening methods include boiling, high temperature and high pressure steam treatment and chemical treatment. The wood trea...

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
