Example Embodiment

[0024] Example 1

[0025] A blood meal protein wood preservative is characterized in that it comprises the following components:

[0026] 6 parts of copper sulfate;

[0027] 8 parts of borax;

[0028] 20 parts of blood meal protein acid hydrolyzate;

[0029] The blood meal protein acid hydrolyzate is obtained by concentrating soybean dregs after pyrolysis, and the protein mass concentration in the blood meal protein acid hydrolyzate is 60%.

[0030] The wood preservative has chelated amino acid copper boron salt, which has good fixation. After entering the wood, it can form a water-insoluble polymer network inside the wood, thereby improving the copper and boron in the wood. The fixation performance in the wood achieves the purpose of long-term anticorrosion. Compared with the blank specimen, the treated wood has no obvious change and the color is uniform. It can be considered that the preservative has basically no effect on the color of the wood. Comparing the appearance ...

Abstract

The invention discloses a blood meal protein wood preservative and a preparation method thereof. The preparation method thereof comprises the following steps of blood powder is pyrolyzed under an acidic condition to obtain a blood powder acidolysis solution, then the blood powder acidolysis solution is mixed with borax and copper sulfate, and compounding is carried out to generate the blood meal protein wood preservative. Compared with the prior art, the blood meal protein wood preservative and the preparation method thereof has the following advantages that the copper sulfate, the borax and blood meal protein are subjected to a chelation reaction to form an amino acid metal salt and an amino acid salt so that a polymer network which is insoluble in water can be formed in the wood, and therefore the service life of anti-corrosion wood can be prolonged.

Description

technical field [0001] The invention relates to the technical field of wood preservation, in particular to a blood meal protein wood preservative and a preparation method thereof. Background technique [0002] Due to the toxicity and low loss resistance of traditionally used wood preservatives, it is easy to cause harm and pollution to humans and the surrounding environment, which is not conducive to environmental protection, and its use has been strictly restricted in some countries. The purpose of the present invention is to provide a preparation method of an environmentally friendly composite wood preservative with good fixation performance, which can effectively penetrate into the interior of the wood, effectively improve the loss resistance and corrosion resistance of the anti-corrosion wood, and there is no need to use it during preparation and use. Toxic by-products are produced, which is in line with the concept of environmental protection and has broad application p...
