Problems solved by technology

[0005] Currently used acidic catalysts, such as oxalic acid, maleic anhydride, etc. Acids, mineral acids such as phosphoric acid and sulfuric acid, Lewis acids such as zinc chloride and titanium chloride, and iodine cannot meet the requirements of low cost and high performance. At the same time, these catalysts react violently and have single functions, and cannot cooperate with furfuryl alcohol resin to further improve wood resistance. Flammability and resistance to biodegradation

Example Embodiment

[0049] Example 1

[0050] Put 810mL of distilled water into a 2L glass beaker and preheat it to 35°C, then slowly add 32g of boron phosphate and 8g of phytic acid in sequence, stir with a magnetic stirrer for 10min until all the solids are dissolved, and obtain a clear, transparent and homogeneous solution, which is to be mixed After the solution was cooled to room temperature, 150 g of furfuryl alcohol was slowly added, and the mixture was magnetically stirred for 10 min to obtain a furfuryl alcohol modified solution.

[0051] The furfuryl alcohol modified liquid prepared above was used to prepare the standard specimen of the furfuryl alcohol resin-modified wood of Example 1.

Example Embodiment

[0052] Example 2

[0053] Put 818mL of distilled water into a 2L glass beaker and preheat it to 35°C, then slowly add 24g of boron phosphate and 8g of ammonium dihydrogen phosphate, stir with a magnetic stirrer for 10min until all the solids are dissolved, and obtain a clear, transparent and homogeneous solution, After the mixed solution was cooled to room temperature, 150 g of furfuryl alcohol was slowly added, and the mixture was magnetically stirred for 10 min to obtain a furfuryl alcohol modified solution.

[0054] The furfuryl alcohol modified liquid prepared above was used to prepare the standard specimen of the furfuryl alcohol resin-modified wood of Example 2.

Example Embodiment

[0055] Example 3

[0056] Put 810mL of distilled water into a 2L glass beaker and preheat to 35°C, then slowly add 32g of zinc borate and 8g of phytic acid in turn, stir with a magnetic stirrer for 10min until all solids are dissolved, and obtain a clear, transparent and homogeneous solution, which is to be mixed After the solution was cooled to room temperature, 150 g of furfuryl alcohol was slowly added, and the mixture was magnetically stirred for 10 min to obtain a furfuryl alcohol modified solution.

[0057] The furfuryl alcohol modified liquid prepared above was used to prepare the standard specimen of the furfuryl alcohol resin-modified wood of Example 3.

Abstract

The invention provides furfuryl alcohol modification liquid, a preparation method and application thereof. The furfuryl alcohol modification liquid contains a catalyst, wherein the catalyst comprises a boron compound and a phosphorus compound, the boron compound is selected from one or more of boric acid, boron phosphate and zinc borate, and the phosphorus compound is selected from one or more of diammonium hydrogen phosphate, ammonium dihydrogen phosphate and phytic acid. According to the invention, the furfuryl alcohol modification liquid is good in storage stability; and when the furfuryl alcohol modification liquid is used for wood modification, modified wood excellent in size stability, flame retardance and corrosion resistance can be obtained, low weight gain and high performance of a furfuryl alcohol modification technology are achieved, and the requirement of one dose for multiple effects is met.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a furfuryl alcohol modified liquid and its preparation method and application. Background technique [0002] With the advancement of carbon neutrality, society's demand for wood continues to increase, and plantation wood has become an important way to increase carbon sink resources and alleviate the contradiction between wood supply and demand. Plantation woods generally have problems such as softness, deformation, flammability, and decay. Therefore, modifying plantation woods to improve their dimensional stability, flame retardancy, and corrosion resistance is an important way to increase wood added value and An important means to prolong the service life of wood. [0003] Wood furfuryl alcohol modification technology refers to the chemical modification technology in which small molecules of furfuryl alcohol are impregnated into wood, condensed and filled wi...
