Problems solved by technology

The first treatment method completely treats trimmings as waste, which has the worst utilization effect and the greatest waste of energy and raw material resources.
Although the second processing method recycles the trimmed materials, it must be "returned" to the furnace for decomposition and hot pressing, which not only increases the secondary energy consumption, but also obtains low-value products, so all aspects of benefits None ideal
The blockboard manufactured by this process is more complicated, the cost is higher, a large amount of wood is consumed, a large amount of leftovers are produced in the production process, and it is difficult to make the ordinary blockboard realize fireproof, moisture-proof and other functions from the process, so the functionality is poor and the grade is low. lower

Embodiment 1

[0036] A general-purpose low-carbon secondary blockboard, mainly composed of a board core 1 and upper and lower cover panels 2; wherein, the board core 1 is mainly made of ordinary fiberboard, plywood or particleboard trimmings as raw materials The thin square strips made are spliced ​​separately, and glued paper strips 3 are used to paste and fix the spliced ​​thin square strips in an "N" shape on the spliced ​​board surface. The upper and lower covering panels 2 adopt ordinary horizontal grain veneer.

Embodiment 2

[0038] A high-grade melamine low-carbon secondary blockboard for high-end purposes, mainly composed of a board core 1 and upper and lower cover panels 2; wherein, the board core 1 is mainly made of ordinary fiberboard, plywood or particleboard trimmings The thin square strips made of raw materials are spliced ​​separately, and glued paper strips 3 are used to paste and fix the spliced ​​thin square strips in an "N" shape on the spliced ​​board surface. The upper and lower covering panels 2 adopt melamine veneer panels.

Embodiment 3

[0040] A high-grade flame-retardant melamine low-carbon secondary blockboard for high-end purposes, mainly composed of a core 1 and upper and lower cover panels 2; wherein, the core 1 is mainly composed of trimmings of flame-retardant fiberboard Thin square strips made of raw materials are spliced, and adhesive tape strips 3 are used to paste and fix the spliced ​​thin square strips in an "N" shape on the spliced ​​board surface. The splicing mode of the thin square strips is dislocation splicing. The upper and lower covering panels 2 adopt melamine veneer panels.

Abstract

The invention discloses a low-carton secondary blockboard and a method for manufacturing the low-carton secondary blockboard. The secondary blockboard mainly comprises a board core, an upper covering panel and a lower covering panel. Thin square bars made of cut edge materials of artificial boards are connected in a slicing mode to form the board core, and the sliced thin square bars are fixed in an N-shaped adhering mode on the spliced board surface through adhesive tape bars. The manufacturing steps of the secondary blockboard comprise the steps of (1) preparing the thin square bars, (2) splicing the board core, (3) paving and assembling, (4) pre-pressing, (5) hot-pressing, (6) cutting edges, (7) sanding and processing and (8) detecting and putting finished products in storage. The low-carton secondary blockboard is simple in manufacturing technology, low in processing cost, environmentally friendly and more superior in comprehensive performance, saves energy, and has inheritance of the artificial boards (mother boards) and good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel manufacturing in the wood processing industry, and relates to a low-carbon secondary blockboard and a manufacturing method thereof. Background technique [0002] With the improvement of my country's economic level and people's living standards, the market demand for wood-based panel products is increasing. At present, my country has become the world's largest producer and consumer of wood-based panels. According to statistics in 2011, my country's annual production capacity of wood-based panels has reached 209.1929 million cubic meters, ranking first in the world. The development of the wood-based panel industry is conducive to alleviating the contradiction between the supply and demand of wood in my country and saving wood resources. However, in the production process of wood-based panels, a large amount of trimmings will be produced. According to estimates, the trimmings generated in t...
