Embodiment 1

[0012] A novel wood fiber softener, the preparation steps of which are as follows:

[0013] Weigh 15 parts by weight of wood vinegar, 3 parts by weight of fatty alcohol polyoxyethylene ether, 15 parts by weight of triisopropanolamine, 4 parts by weight of 1,4-butanediol, 53 parts by weight of deionized water, and 2 parts by weight of trihydroxy Methyl propane, 3 parts by weight of methyl glucoside, 2 parts by weight of sodium tripolyphosphate, 3 parts by weight of sodium dodecyl sulfate; after mixing uniformly in proportion, proceed with a stirrer at a speed of 150r / min at 55°C The softener was obtained after stirring for 8 minutes.

[0014] When in use, spray the prepared softener evenly on the side pasted with wood fiberboard and melamine impregnated paper, and the spraying amount is 80-90g / m 2 , use after standing for 3 hours after spraying.

[0015] The technological steps of treating fiberboard with water as a softener are as follows:

[0016] Heat the deionized water ...

Embodiment 2

[0026] A novel wood fiber softener, the preparation steps of which are as follows:

[0027] Weigh 20 parts by weight of wood vinegar, 2 parts by weight of fatty alcohol polyoxyethylene ether, 10 parts by weight of triisopropanolamine, 3 parts by weight of 1,4-butanediol, 60 parts by weight of deionized water, 1 part by weight of three Hydroxymethylpropane, 1 part by weight of methyl glucoside, 1 part by weight of sodium tripolyphosphate, and 2 parts by weight of sodium lauryl sulfate.

Abstract

The invention provides a novel wood fiber softening agent. The novel wood fiber softening agent comprises, by weight, 15-20 part of pyroligneous, 2-3 parts of fatty alcohol-polyoxyethylene ether, 10-15 parts of triisopropanolamine, 3-4 parts of 1,4-butanediol, 1-2 parts of trihydroxy trimethylopropane, 1-3 parts of methyl glucoside, 1-2 parts of sodium tripolyphosphate, 2-3 parts of lauryl sodium sulfate and 50-60 parts of deionized water. During preparation of the novel wood fiber softening agent, after the components are evenly mixed in proportion, stirring is conducted at the temperature below 50-60 DEG C for 5-10 min at the speed of 60-250 r / min, so that the softening agent is prepared. When the novel wood fiber softening agent is in use, the prepared softening agent is evenly sprayed on the side, adhering to tripolycyanamide impregnated paper, of a wood fiber board, the spraying amount is 80-90 g / m<2>, and standing is conducted for 0.5-3 h after spraying. The novel environment-friendly wood fiber softening agent mainly has the four effects that firstly, the permeability of the fiber board is improved; secondly, the mechanical property of the fiber board in the secondary pressurization process is improved; thirdly, the dimensional stability of the fiber board is improved; and fourthly, the anti-mold property of the fiber board is achieved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of decorative wood-based panels, and in particular relates to a novel wood fiber softener for spraying medium-density fiberboards to achieve softening, a preparation method and an application method thereof. Background technique [0002] Medium density fiberboard is a product made by using wood processing residues or non-wood plant fibers as raw materials and pressing with adhesives. It is used in the field of deep processing of wood-based panels. In recent years, a new use is used for molding to prepare furniture bases for special decorative purposes. material. At present, the softening methods of medium-density fiberboard substrates mainly include soaking in ammonia water and spraying with water. The disadvantage of softening with ammonia is that it will produce gas with a strong pungent smell and pollute the environment. The disadvantage of water spraying is that the action time is long and the water sof...
