[0002] Wood is a biopolymer material, which is vulnerable to the harm and degradation of biological factors such as fungus and insects, such as decay and insects. Wood preservatives can overcome this defect. Copper salts are currently more commonly used wood preservatives. Due to their low cost and It can effectively prevent the harm of microorganisms to wood, and is widely used. After copper preservatives treat wood, the fixation performance of its active ingredients in wood is an important factor in determining its anti-corrosion and insect-proof effects. However, copper salt itself has poor loss resistance and is harmful to human and animal health. have many adverse effects on the natural environment

Embodiment 1

[0017] The preservative involved in this embodiment is composed of the following raw material components: 30% of basic copper carbonate, 6% of hexaconazole, 20% of rosin, 30% of aminoethanol, 25% of ammonia, 10% of toluene and fatty alcohol polyoxygen Vinyl ether 5%.

[0018] The preparation steps of described preservative are as follows:

[0019] 1), adding rosin to the alkali solution, stirring at 100°C for 7 hours to obtain a rosin soap solution;

[0020] 2), then add water to the reaction kettle, quickly add the copper salt, stir, and cool down when the copper salt is completely dissolved;

[0021] 3), the obtained rosin soap solution and copper salt are mixed, heated and evaporated to obtain rosin copper;

[0022] 4) Heat the rosin copper to a molten state, add an organic solvent and a surfactant, put it into a mixer with a rotation speed of 1100r / min, and stir evenly.

Embodiment 2

[0024] The preservative involved in this embodiment is composed of the following raw material components: copper sulfate 16%, cyproconazole 0.5%, rosin 5%, aminoethanol 6%, ammonia 5%, xylene 4% and alkylaryl Polyoxyethylene ether 2%.

[0025] The preparation steps of described preservative are as follows:

[0026] 1), adding rosin to the alkali solution, stirring at 60° C. for 1 hour to obtain a rosin soap solution;

[0027] 2), then add water to the reaction kettle, quickly add the copper salt, stir, and cool down when the copper salt is completely dissolved;

[0028] 3), the obtained rosin soap solution and copper salt are mixed, heated and evaporated to obtain rosin copper;

[0029] 4) Heat the rosin copper to a molten state, add an organic solvent and a surfactant and put it in a mixer with a rotating speed of 500r / min to stir evenly.

[0030] As can be seen from the above examples: adding quaternary ammonium salt cationic surfactant in the preparation of the present i...

Abstract

The invention discloses a rosin-copper composite wood preservative and a preparation method thereof. The preservative is composed of the following raw material components: copper, triazole compounds, rosin, aminoethanol, ammonia, organic solvent and surfactant. The preparation steps of the preservative are as follows: 1), adding rosin to the alkali solution, and stirring to obtain a rosin soap solution; 2), adding water and copper salt to the reaction kettle, and stirring; 3), adding the obtained rosin The soap solution and the copper salt are mixed, heated and evaporated to dryness to obtain the copper rosin; 4) heating the copper rosin until melting, adding an organic solvent and a surfactant and putting it into a blender to stir evenly. The invention has the advantages of high drug efficacy and low usage, simple preparation process, cheap and easy-to-obtain raw materials, and does not require harsh reaction conditions, which greatly reduces the cost.

Description

technical field [0001] The invention relates to a preservative, in particular to a rosin-copper composite wood preservative and a preparation method thereof. Background technique [0002] Wood is a biopolymer material, which is vulnerable to the harm and degradation of biological factors such as fungus and insects, such as decay and insects. Wood preservatives can overcome this defect. Copper salts are currently more commonly used wood preservatives. Due to their low cost and It can effectively prevent the harm of microorganisms to wood, and is widely used. After copper preservatives treat wood, the fixation performance of its active ingredients in wood is an important factor in determining its anti-corrosion and insect-proof effects. However, copper salt itself has poor loss resistance and is harmful to human and animal health. It has many adverse effects on the natural environment. Contents of the invention [0003] The main purpose of the present invention is to propos...
