Problems solved by technology

Among them, the ubiquitous problem is: due to the strong hygroscopicity and easy aging of the wicker material, in the environment of humidity and strong light, the existing flame retardant treatment agent will not only cause adverse effects on the stability of the willow material during the treatment process. Affected by its own hygroscopicity, it is easy to precipitate and lose from the surface of the wicker, and if things go on like this, it will lose its flame retardant effect
As a result, the flame retardant effect of wicker crafts cannot reach the level pursued

Abstract

The invention relates to the technical field of wicker handicraft development, and discloses a long-term flame-retardant treatment method suitable for wicker handicrafts. The prepared flame-retardant material is infiltrated into the willow material by using a treatment method of heating and impregnating under normal pressure. It will have adverse effects on the dimensional stability of willow materials. The flame retardant material is hydrophobic and can shield the influence of moisture. Even under high humidity and strong light, it can exist stably in willow materials without affecting the resistance The flame retardant effect produces fading effect, strong loss resistance, and remarkable flame retardant effect; the flame retardant material is economical and environmentally friendly, and is very stable in physical and chemical properties, with large specific heat capacity, heat insulation and oxygen insulation, and can produce free radical inhibitors when heated , the conditions for interrupting the formation of combustion reactions expand the scope of application of willow crafts in other fields.

Description

technical field [0001] The invention belongs to the technical field of wicker handicraft development, and in particular relates to a long-acting flame-retardant treatment method suitable for wicker handicrafts. Background technique [0002] As a national intangible cultural heritage, wicker crafts not only have high artistic value, but also can be used as practical furniture. Its shapes are changeable, its colors are rich, and its materials are environmentally friendly. As a representative of folk traditional handicrafts, it is deeply loved by people. [0003] The materials used in wicker handicrafts are natural plant resources, which have the characteristics of being natural and environmentally friendly. But at the same time, there is also a natural defect, that is, flammability. Every year, accidents caused by fires have brought great harm to people's lives and properties. With the development of technology, a comprehensive understanding of the inheritance and protectio...
