Embodiment 1

[0014] Take raw materials: (weight percentage, the same below)

[0015] Volume concentration 99.5% ethylamine 15%

[0016] Boric acid 60%

[0017] water 25%

[0018] Preparation method: Mix the above-mentioned raw materials evenly.

Embodiment 2

[0020] Take raw materials:

[0021] Volume concentration 99.5% ethylamine 20%

[0022] Boric acid 60%

[0023] water 20%

[0024] The preparation method is the same as that of Example 1.

Embodiment 3

[0026] Take raw materials:

[0027] Volume concentration 99.5% ethylamine 10%

[0028] Boric acid 50%

[0029] water 40%

[0030] The preparation method is the same as that of Example 1.

[0031] usage:

[0032] Dilute the preservative of the above formula with water so that the boric acid content is 20%, spray on the wood sheet at a dosage of 30g / square, and dry it at 140 ° C for 4-5min, the boric acid will completely penetrate the sheet. .

[0033] Urea-formaldehyde resin used for wood sheet, the temperature is 110 ℃, the pressure is 9.8 × 10 5 Under the condition of Pa, the adhesive is pressed to form a laminate, and then brushed with the preservative aqueous solution of the present invention (diluted to a boric acid content of 15%), that is, it has a good anti-corrosion effect.

Abstract

The invention discloses a preservative for a rubber wood chip. The preservative is prepared from the raw materials in percentage by weight: 10 to 20 percent of ethylamine, 50 to 60 percent of boric acid, and 20 to 40 percent of water. In the preservative for the rubber wood chip, the permeability of the preservative containing the boric acid can be improved well due to the ethylamine. Simultaneously, the preservative can react with dissociated formaldehyde, so that the corrosion to wood is avoided. During use, the preservative of the formula is diluted in water so that the content of the boric acid is 20 percent; and 30g of preservative is sprayed onto one square meter of the wood chip of which the thickness is 1.5mm, and then the wood chip is dried at the temperature of 140 DEG C for 4 to 5 minutes to ensure that the boric acid can permeate the sheet completely. The preservative can also be brushed onto a laminated wood board for corrosion prevention. The preservative has a good corrosion preservation function.

Description

technical field [0001] The invention relates to wood preservative technology, in particular to a rubber wood chip preservative and its application. Background technique [0002] Because rubber wood only contains sapwood, like other sapwood species, it is not resistant to decay. Rubberwood is even less resistant to decay than bamboo and oil palm stalks. In the warm and humid southern regions of our country, there is a serious problem of wood decay, and fresh sawn wood must be quickly treated with preservative and dry naan to control the main factor of rubber wood decay, that is, the parenchyma cells of wood contain a lot of sugar and Starch, carbohydrates up to 8%, generally only 1-3% of wood. [0003] Traditional wood preservatives, which prevent wood rot and moth infestation, have been used for many years. But these preservatives contain chromium and arsenic, which can easily contaminate water and soil, posing potential threats to people, animals and plants. SU...
