Problems solved by technology

[0003] At present, the wood preservatives used in the world are mainly CCA preservatives. Because this kind of wood preservatives contain toxic substances such as arsenic and chromium, which are not conducive to environmental protection, and the preparation cost is high, their use has been strictly restricted in some countries.
The preparation level and efficacy of wood preservatives in my country still lag behind foreign countries, mainly relying on imports, which increases the preparation cost of wood products to a certain extent. Therefore, further research and development of wood preservatives is needed

Abstract

The invention provides a wood preservative. The wood preservative comprises the following main ingredients in percentage by weight: 8-12% of nanometre copper oxide particles, 4-6% of sodium metabisulfite, 2-4% of tebuconazole, 5-8% of polyethylene glycol, 1-3% of copper naphthenate, 2-5% of acetic acid, and the balance deionized water. The invention discloses a wood preservative. The wood preservative is reasonable in ingredient configuration, simple and convenient in preparation process, and moderate in cost; the prepared preservative has good use performance, has no toxic by-products generated during preparation and use processes, meets the environmental protection concept, and can be widely applied to various natural wood, fibre board and shaving board products, and machined parts.

Description

technical field [0001] The invention relates to a wood preservative, in particular to a novel wood preservative with high efficiency, environmental protection and low cost, which belongs to the technical field of wood products. Background technique [0002] Wood is a natural biological material, which is widely used in industrial and civil construction, furniture, decoration and other fields, and it is closely related to people's life. Wood products have obvious biological characteristics, so they are very vulnerable to bacteria, insects and microorganisms, causing discoloration, decay and moth-eaten phenomena, which seriously affect the performance and service life of wood products, increase the consumption of wood, and not only waste resources , It also limits the application field of wood, thus bringing huge economic losses. Therefore, for wood preservation, in addition to strengthening the sanitation management from raw materials to product processing, targeted preserva...
