Embodiment 1
[0032] The wood improver is made up of the following materials in parts by weight:
[0033] 23-26 parts of sodium carboxymethylcellulose at pH 4.5; 3-4 parts of gum arabic; 4-5 parts of octyl 2-cyanoacrylate; 35-37 parts of ethanol; 1-2 parts of ammonium polyphosphate-boric acid Zinc composite flame retardant, in which the weight of ammonium polyphosphate is twice that of zinc borate, the degree of polymerization of ammonium polyphosphate is 23-25, the phosphorus content is 30%, and the nitrogen content is 16%; 0.2-0.3 parts of citric acid 18-19 parts of water; 0.06-0.08 parts of benzoic acid; 13-15 parts of polylactide-glycolide with a molecular weight of 6000-8000; 0.03-0.04 parts of benzalkonium chloride.
[0034] The wood improver is prepared according to the following production procedures, comprising the following steps:
[0035] 1) Add ethanol and water to the reaction kettle, then add sodium carboxymethylcellulose, stir at a speed of 300 rpm for 30 minutes or continue...
Embodiment 2
[0049] The wood improver is made up of the following materials in parts by weight:
[0050] 26 parts of sodium carboxymethyl cellulose with a pH of 4.5; 3 parts of gum arabic; 4 parts of octyl cyanoacrylate; 37 parts of ethanol; 1 part of ammonium polyphosphate-zinc borate composite flame retardant, wherein ammonium polyphosphate The weight is twice that of zinc borate, the degree of polymerization of ammonium polyphosphate is 23-25, the phosphorus content is 30%, and the nitrogen content is 16%; 0.2 parts of citric acid; 19 parts of water; 0.07 parts of benzoic acid; 13 parts Polylactide-glycolide with a molecular weight of 6000-8000; 0.03 parts of benzalkonium chloride.
[0051] The preparation method of the wood improver and the method of using the wood improver to improve wood are the same as in Example 1.
Embodiment 3
[0053] With reference to the evaluation method of the embodiment in CN102626941, the modified wood of the present invention is evaluated for performance, and the results are as follows in Table 1:
[0054] Table 1 Comparison results of performance evaluation of wood improver of the present invention
[0055]
[0056]
[0057] The above results show that the profile obtained through the technical solution of the present invention has excellent physical properties, overcomes the shortcoming of the fast-growing material itself being soft, and has good heat-resistant / humid dimensional stability.
