Production method of weather-proof low-formaldehyde medium-density fiber plate special for cabinet

Abstract

The invention discloses a production method of a weather-proof low-formaldehyde medium-density fiber plate special for a cabinet. The production method comprises the steps of (1) raw material pretreatment; (2) screening; (3) stewing softening; (4) grinding; (5) gluing and drying; (6) prepressing; (7) hot pressing; (8) sawing and sanding; (9) hot pressing for veneer; and (10) edge sealing and acquisition of a finished product. According to the production method, eucalyptus bark and branches and waste leftover materials of plate manufacturing are adopted as main raw materials, other wood is added, waste is made profitable, and full and effective utilization for wood resources can be achieved; and modified paraffin and an weather-proof urea resin adhesive are added, the production process isstrictly controlled, water-proof and weather-proof properties are greatly improved, the formaldehyde content is low, and the manufactured medium-density fiber plate special for the cabinet has the advantages of being environmentally-friendly in use, low in formaldehyde content and excellent in weather-proof property, and is safe, environmentally-friendly and low-formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, in particular to a production method of a weather-resistant low-aldehyde medium-density fiber cabinet special board. 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...

AI Technical Summary

Problems solved by technology

The solid wood boards are made of natural materials, the resource is scarce and the price is high, the color is also determined by the tree species, there are few choices, and the environment that is too dry and humid is not suitable for solid wood, so it is more troublesome to maintain, and the acid and alkali resistance is poor; the current domestic cabinets There is still a gap between the technological level and the international level. The domestic solid wood door panels are not well-crafted, and problems such as deformation, cracking, and rough surface are prone to occur.
