Embodiment 1

[0016] A flame retardant treatment method for willow handicrafts comprises the following steps:

[0017] (1) Add 0.10 mole of isobutyraldehyde into a 100m1 three-necked flask equipped with a thermometer, reflux condenser and constant pressure dropping funnel, and under magnetic stirring, add 45m1 of anhydrous ethanol solution dissolved with 0.05 mole of potassium hydroxide from a constant The pressure dropping funnel was slowly added dropwise to the three-necked flask. During the reaction, the water bath was used to control the temperature in the range of 55-65°C. The reaction time was 3 hours. After the reaction was completed, the ethanol solvent was recovered, and 50ml of cold water was added to the reaction system. The pale yellow solid was no longer precipitated, and was subjected to suction filtration, washing, and recrystallization to obtain an intermediate;

[0018] (2) Add the prepared intermediate into a three-necked flask, add 0.06 mole of freshly steamed phosphorus ...

Embodiment 2

[0024] A flame retardant treatment method for willow handicrafts comprises the following steps:

[0025] (1) Add 0.12 mole of isobutyraldehyde into a 100m1 three-neck flask equipped with a thermometer, reflux condenser and constant pressure dropping funnel, and under magnetic stirring, dissolve 48m1 of anhydrous ethanol solution containing 0.06 mole of potassium hydroxide from constant The pressure dropping funnel was slowly added dropwise to the three-necked flask. During the reaction, the temperature was controlled by a water bath in the range of 55-65°C. The reaction time was 3.5 hours. After the reaction was completed, the ethanol solvent was recovered, and 55m1 of cold water was added to the reaction system. The pale yellow solid was no longer precipitated, and was subjected to suction filtration, washing, and recrystallization to obtain an intermediate;

[0026] (2) Add the prepared intermediate into a three-necked flask, add 0.07 moles of freshly distilled phosphorus ox...

Embodiment 3

[0032] A flame retardant treatment method for willow handicrafts comprises the following steps:

[0033] (1) Add 0.15 mole of isobutyraldehyde into a 100m1 three-necked flask equipped with a thermometer, reflux condenser and constant pressure dropping funnel, and under magnetic stirring, dissolve 50m1 of anhydrous ethanol solution with 0.08 mole of potassium hydroxide from constant The pressure dropping funnel was slowly added dropwise to the three-necked flask. During the reaction, the temperature was controlled by a water bath in the range of 55-65°C. The reaction time was 4 hours. After the reaction was completed, the ethanol solvent was recovered, and 60m1 of cold water was added to the reaction system. The pale yellow solid was no longer precipitated, and was subjected to suction filtration, washing, and recrystallization to obtain an intermediate;

[0034] (2) Add the prepared intermediate into a three-necked flask, add 0.08 mol of freshly distilled phosphorus oxychlorid...

Abstract

The invention relates to the technical field of willow garden product processing and discloses a flame retardant treatment method for willow garden products. According to the flame retardant treatment method, a flame-retardant agent obtained through preparation is added to phenolic resin which is low in molecular weight, and dipping and hot pressing treatment is conducted on the willow garden products, wherein the concentration of the flame-retardant agent ranges from 0.2% to 0.3%. The phosphorus-based flame-retardant agent obtained through preparation is an expansion type flame-retardant agent, substances capable of capturing free radicals can be generated in the decomposition process, and thus a free radical chain reaction is cut off and the purposes of flame retarding and smoke inhibition are achieved; a polymer covers the surface of the willow garden products, so that a protective layer is formed, and the flame retarding effect is achieved; the problem that the phenolic resin can deteriorate mechanical performance of wood is solved; and in addition, the flame-retardant agent has the non-volatile characteristic. The flame retardant treatment method aims at solving the problem that the willow garden products are inflammable; the characteristic that the phenolic resin which is low in molecular weight is good in permeability to willow is utilized, and the novel flame-retardant agent is prepared; and mechanical performance of the willow garden products cannot be deteriorated while flame retarding performance of the willow garden products is improved.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing willow handicrafts, and in particular relates to a flame-retardant treatment method for willow handicrafts. Background technique [0002] Willow is one of the traditional Chinese folk handicrafts. In ancient times, it was only used as an ordinary daily utility, and it did not rise until the last few decades of the 20th century, and it gradually became an item for export in some parts of China. There are three willow weaving production bases in China: Shandong, Henan and Anhui. Wicker is soft and easy to bend, well-proportioned in thickness, and elegant in color. Through novel designs, it can be woven into various practical handicrafts that are simple, natural, beautiful in shape, light and durable. Its products include: wicker boxes (bags), rice baskets, vegetable baskets (round and oval), fences, needlework baskets, kang mats, reed foil, etc. With the continuous developmen...
