Abstract

The invention relates to the technical field of processing of furniture timbers and discloses a preservative for processing poplar-made furniture. The preservative is prepared from the following components in parts by weight: 15 to 16 parts of sodium polyacrylate, 10 to 12 parts of polyvinyl alcohol, 45 to 50 parts of a verbena officinalis extracting solution, 20 to 25 parts of ethanol, 4 to 6 parts of sodium carbonate, 1 to 2 parts of sodium carboxymethyl cellulose and 800 to 900 parts of water; the preservative does not contain toxic components and heavy metal elements, can be used for killing mildew on the surface of poplar and also can permeate into the timbers to prevent wood cellulose from inducing mildewing and worm damages; when the preservative is used for processing the poplar, the cost is less and the effect is good; the poplar treated by the method can reduce performance shortage and cost loss, caused by poplar corrosion; the anticorrosion performance and stability of the poplar are greatly improved and the service life of the poplar is prolonged so that the service life of the poplar-made furniture is prolonged; the preservative has important significance on timber saving and forest resource and environment protection.

Description

technical field [0001] The invention belongs to the technical field of furniture material processing, and in particular relates to a preservative for poplar furniture processing. Background technique [0002] Poplar, also known as "small leaf poplar", often has a satin-like luster, so it is also called "satin poplar". It is often used as an attachment to elm furniture and the fetal bone of lacquer furniture on ancient furniture. It is a commonly used wood in northern my country. It is soft, stable, and cheap. Due to the loose fiber structure and relatively poor quality of poplar wood, its application range is greatly limited. At present, it is mainly used as solid wood composite floor core board, building formwork, bottom board, short-cycle industrial raw material or road and river greening tree species. [0003] Poplar wood is unstable in size, and is easily attacked by fungi, insects and other organisms, and decays quickly, which limits its application in the field of fur...
