Production method of fireproof and flame-retardant type medium-density fiber wood floor

Abstract

The invention discloses a production method of a fireproof and flame-retardant type medium-density fiber wood floor. The production method comprises the steps of (1) pretreatment of raw materials; (2)screening; (3) stewing softening operation; (4) grinding operation; (5) glue application and drying; (6) pre-pressing operation; (7) hot-pressing operation; (8) sawing and sanding; (9) glue coating and veneering hot-pressing operation; and (10) preservation and grooving, so that the finished product is obtained. According to the production method, the eucalyptus bark, branches and waste leftovermaterials which remain after board manufacturing is accomplished are used as main raw materials, then other miscellaneous trees are added, the waste is turned into the wealth, and therefore the sufficient and effective utilization of timber resources can be achieved; and due to the fact that modified paraffin and flame-retardant urea-formaldehyde resin adhesives are added, the fireproof and flame-retardant performance of the wood floor can be greatly improved, and the produced medium-density fiber wood floor is excellent in fireproof and flame-retardant performance, good in water resistance and low in formaldehyde content, and is a safe, environmentally friendly and durable wood floor.

Description

technical field

[0001] The invention belongs to the technical field of wood-based panels, in particular to a production method of a fire-proof and flame-retardant 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...

[0058] A method for producing a fire-resistant and flame-retardant medium-density fiber wood floor, the specific steps of which are as follows:

[0059] (1) Raw material pretreatment: Mix eucalyptus scraps and other miscellaneous woods evenly according to the weight ratio of 1:0.4, cut into pieces with a length of 4-5cm and a width of 0.5-0.6cm;

[0060] The eucalyptus leftovers include eucalyptus bark, branches and leftover waste leftovers from the manufacture of boards; the miscellaneous woods include pine, basswood and eucalyptus, and the wood is left to air for 20 days before use;

[0061] (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;

[0062] (3) Cooking and softening: transport the wood chips 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 0.15Mpa...
