AI Technical Summary

Problems solved by technology

1. In order to solve the problems of high production cost and environmental pollution caused by the existing water-borne wood preservatives that cause environmental pollution due to metal content, and the large use of volatile organic compounds (volatile organic compounds, VOCs) in organic solvent-based wood preservatives; 2. In order to reduce the toxicity to bees and fish, etc., it is more friendly to the environment; 3. The modified triazole compound is used as a fungicide, thereby improving the anti-loss performance and making the use of organic wood preservatives more extensive. Better use effect and longer use time

Abstract

Water-borne composite organic wood preservative and its preparation method and application, the mass percentage of each component of the wood preservative is: organic insecticide, fungicide 5-15%, organic solvent 25-40%, surface active The organic fungicides and insecticides are triazole compounds, butyl iodopropynyl carbamate (3‑iodo‑2‑propynyl‑butyl‑carbamate, referred to as IPBC) 1. The organic insecticide is at least one of imidacloprid and pyrethroids; the organic solvent is at least one of cyclohexanone, dimethylformamide (DMF), and xylene. The wood preservative of the invention has good anti-corrosion and anti-mildew effect, low consumption, good anti-loss performance, and is environmentally friendly, and can be widely used in indoor furniture, indoor decoration materials, outdoor gardens, buildings 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...
