Problems solved by technology

However, due to the material characteristics of wooden furniture itself, it has the disadvantages of being flammable, easy to smoke when burned, and absorbing water to expand.
At the same time, in the design of traditional custom-made furniture, due to the insufficient strength of the particleboard, it is easy to deform under a slightly larger pressure, and other materials are needed to cooperate with the support

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...
