Abstract

The invention relates to a water-borne composite organic wood preservative, a preparation method and application thereof. The wood preservative comprises the following components by mass: 5-15% of an organic insecticide and bactericide, 25-40% of an organic solvent, 15-20% of a surfactant, and the balance water. The organic insecticide and bactericide is at least one of a triazole compound, 3-iodo-2-propynyl-butyl-carbamate (called IPBC for short), imidacloprid and pyrethroid substances. The organic solvent is at least one of cyclohexanone, dimethylformamide (DMF), and xylene. The wood preservative provided by the invention has good antiseptic and mould proof effects, low dosage, good loss resistance and environmental friendliness, and can be widely used in indoor furniture, indoor decoration materials, outdoor gardens, constructions and the like.

Description

technical field [0001] The invention belongs to the field of wood preservatives, and relates to a water-borne composite organic wood preservative, a preparation method thereof, and an application in wood preservatives. Background technique [0002] Water-borne preservatives are the most widely used wood preservatives in the world. Commonly used are chromium copper arsenate (CCA), copper quaternary ammonium (ACQ), copper azole (CA), etc., but they contain chromium, arsenic and Copper and other elements will cause certain environmental pollution during the production and use of preservative wood, and its preservative wood products are not suitable for contact with humans and animals, and many countries have restricted their use. Therefore, metal-free water-borne organic wood preservatives have become the focus of development of new wood preservatives. Compared with CCA, ACQ, etc., water-borne organic wood preservatives are environmentally friendly and easy to recycle. However...
