A kind of flame-retardant and moisture-proof super-strength particleboard and its preparation method

Abstract

The invention relates to the technical field of wood-based panel manufacturing, and specifically discloses a method for preparing a flame-retardant and moisture-proof super-strength particleboard, including: preparation and screening of shavings; activation of shavings in an activation solution and microwave activation; and pretreatment in a conditioner , the regulator is 75 to 90 parts of deionized water, 5 to 10 parts of heavy alkylbenzene sodium sulfonate or sodium dodecylbenzene sulfonate, 1 to 4 parts of cetyltrimethylammonium bromide, 2~5 parts of dodecylphenol polyoxyethylene ether and 4~8 parts of kerosene are blended and then emulsified by high-speed shearing at 40~50°C; impregnated with shavings for modification; dried shavings, sizing, paving and molding , preheating and flat pressing to obtain a flame retardant and moisture-proof super strong particle board. The prepared one has good flame-retardant and fireproof properties, stable structure, good water resistance, good machining performance, high static bending strength and strong impact resistance.

Description

technical field

[0001] The invention belongs to the technical field of wood-based panel manufacturing, and in particular relates to a flame-retardant and moisture-proof super-strength particleboard and a preparation method thereof. Background technique

[0002] Particleboard is a kind of man-made board made of wood or other wood fibers, prepared by shavings, dried and sorted, applied with adhesives and other additives, paved, pre-pressed, and hot-pressed. With the development of the economy and the improvement of people's quality of life, the domestic custom furniture industry has developed rapidly. As the main base material of custom furniture, the demand for particleboard is increasing day by day. However, due to the material characteristics of wooden furniture itself, it has the disadvantages of being flammable, easy to smoke when burned, and swollen by absorbing water. At the same time, in the design of traditional custom-made furniture, due to the insufficient strength...

Embodiment 1

[0028] A method for preparing a flame-retardant and moisture-proof super-strength particleboard, comprising the following steps:

[0029] (1) Chip the eucalyptus wood raw material to obtain wood chips, screen the wood chips, and screen out wood chips with a length of 40-80 mm and a length of less than 40 mm, and use a ring-type long planer for wood chips with a length of 40-80 mm Process into wood shavings, and process wood chips of different sizes into wood shavings with ordinary shaving machines, and wood chips with a length of less than 40mm are processed into wood shavings with ordinary shaving machines;

[0030] A secondary vibrating screen is installed at the wood shaving outlet of the ring-type long wood planer. The apertures of the secondary vibrating screens are 20mm×60mm and 10mm×40mm respectively, and the super large shavings, large shavings, coarse shavings, and For fine shavings, the length of super large shavings is 60-80mm, the length of large shavings is 40-59m...
