Embodiment 1

[0040] A kind of production method of high moisture-proof medium-density fiber wood floor, concrete steps are:

[0041] (1) Raw material pretreatment: Mix eucalyptus scraps with other miscellaneous woods according to the weight ratio of 1:0.2, and cut them into pieces with a length less than 5cm and a width less than 1cm;

[0042] The eucalyptus leftovers are eucalyptus bark, branches and waste leftovers from the manufacture of boards; the miscellaneous woods are birch and beech, and the wood is left to air for 18 days before use.

[0043] (2) Sieving: Sieve the wood chips obtained above to remove silt and debris with a particle size of less than 0.2cm, and remove iron through strong magnetic attraction;

[0044] (3) Cooking and softening: transport the wood fragments into the cooking tank, add an appropriate amount of water to soak for 30 minutes, then pass steam into the cooking tank, keep the pressure in the tank at 0.2Mpa, cook for 1 minute, and obtain cork with a water co...

Abstract

The invention discloses a production method of a high-dampproofness medium-density fiber wood floor. The production method comprises the steps of (1) raw material pretreatment, (2) screening, (3) stewing and softening, (4) grinding, (5) gluing and drying, (6) pre-pressing, (7) hot pressing, (8), cooling, sawing and sanding, (9) glue application and veneering hot pressing, and (10) curing and grooving, and obtaining a finished product. Eucalyptus bark, branches and waste leftover materials left by plate manufacturing are utilized as main raw materials, pine, basswood, birch, fraxinus mandshurica, beech, acer mono maxim, lauan and other weedtrees are added, waste is turned into wealth, and wood resources can be fully and effectively utilized; and modified paraffin and a dampproof urea-formaldehyde resin adhesive are added, the dampproofness of the manufactured wood floor is good, the water resisting property is good, the formaldehyde content is low, the compressive strength is high, thefree formaldehyde content meets the relevant standard requirement, and the formaldehyde emission meets the requirement of E1 level in the GB / T 18580 standard.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, in particular to a production method of a high moisture-proof medium-density fiber wood floor. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly includes three major categories of products: plywood, shaving (particle) board and fiberboard, with hundreds of extended products and deep-processed products. Plywood is made by steaming and softening logs, rotary cutting into large sheets, and then placing the wood fiber directions perpendicular to each other, bonding them with synthetic resin glue with good water resistance, and then pressurizing, drying, sawing, and surface trimming. of plates. The number of layers is an odd number, generally 3 to 13 layers, which are called thr...
