Abstract

A flame-retardant leaf-wood chip board and a preparation method thereof are provided, which comprises two leaf panels and one wood chip core board. The wood chip core board is sandwiched by two layers of leaf panels and is formed by adhering and extruding through a special environment-friendly adhesive. The method comprises two processes of manufacturing an environment-friendly adhesive, manufacturing a flame-retardant leaf sawdust core plate and manufacturing the flame-retardant leaf sawdust core plate, wherein the manufacturing of the flame-retardant leaf sawdust core plate is divided into manufacturing of a leaf panel and manufacturing of a sawdust core plate.

Description

Flame-retardant leaf wood chip board and preparation method thereof
Technical Field
The invention relates to the technical field of flame-retardant boards, in particular to a flame-retardant leaf wood chip board and a preparation method thereof.
Background
A large amount of fallen leaves on trees become garbage, so that the workload of sanitation workers is increased, the loading, unloading and transportation amount is increased, resources are wasted, the house building tends to be light in weight, the decoration material is flame-retardant and free of formaldehyde, and the national requirement on fire prevention and flame retardance in the building material industry is high. There is an urgent need for a fire-resistant and flame-retardant fiberboard to replace formaldehyde-containing and non-fire-resistant wood-based fiberboard.
Disclosure of Invention
In order to overcome the defects that the environment is influenced by changing the conventional leaves into garbage and the existing rubber fiber board contains formaldehyde and is not flame retardant, the invention provides the flame-retardant leaf wood chip board, which not only can be cut and nailed like a wood board, but also is flame-retardant and formaldehyde-free.
The technical scheme adopted by the invention for solving the technical problems is as follows: in order to solve the problem that the existing glue fiber board contains formaldehyde and is not flame-retardant, the invention provides the flame-retardant leaf wood chip board, which not only can be cut and can be nailed on the board like a wood board, but also is flame-retardant and formaldehyde-free.
The technical scheme adopted by the invention for solving the technical problems is as follows: a flame-retardant leaf wood chip board comprises two leaf panels and a wood chip core board. The wood chip core board is sandwiched by two layers of leaf panels and is formed by adhering and extruding through a special environment-friendly adhesive.
The invention provides a flame-retardant leaf wood chip board and a preparation method thereof.
1. The environment-friendly adhesive is prepared by processing 6 raw materials, wherein first calcium carbonate with the content of 99.9% is ground into 0.5 mu m through counter-flow vibration, second calcium oxide with the content of 99.9% is ground into 0.5 mu m through airflow, third zeolite is ground into 0.5 mu m through airflow, fourth gypsum is ground into 0.5 mu m through airflow, fifth wood chips are ground into bamboo pulp through a beater, and sixth fresh pine branches and pine needles are also ground into pine pulp through a beater. Proportioning; 10% of calcium carbonate powder, 10% of calcium oxide powder, 25% of zeolite powder, 5% of gypsum powder, 25% of bamboo pulp and 25% of pine pulp. 4 kinds of powder above 0.5 mu m of calcium carbonate powder, calcium oxide powder, zeolite powder and gypsum powder can be mixed according to the proportion, and are packaged for standby after being uniformly stirred, and the bamboo pulp and the pine pulp are separately packaged. When in use, the 4 kinds of powder are added into the bamboo pulp and the pine pulp on site to be mixed and stirred evenly, and then the mixture can be used after being mixed.
2. The leaf panel is manufactured by washing the leaves to remove sludge and sand, feeding the leaves into a counter-roller machine, coating an environment-friendly adhesive, moving the leaves forwards, continuously flattening the leaves, feeding the leaves into a jigsaw machine, splicing the leaves according to a designed pattern, feeding the leaves into the counter-roller machine to extrude the panels, manufacturing the wood chip core, uniformly stirring the environment-friendly adhesive and the wood chips, feeding the leaves into an extruder to continuously extrude the wood chip core, and finally, extruding the wood chip core into a paper-making machine, wherein the leaf panel is manufactured by removing the sludge and,
Because the leaf panel and the sawdust core board are manufactured on site by the environment-friendly adhesive, the production line immediately and automatically sends to the next process, and when the environment-friendly adhesive is combined with the leaf panel and the sawdust core board, the leaf panel and the sawdust core board which are bonded by the environment-friendly adhesive are not dried, the sawdust core board only needs to be clamped between the two leaf panels for extrusion, and can be bonded into a whole, the environment-friendly adhesive is not needed, and the flame-retardant leaf sawdust board is manufactured by only compacting one flame-retardant leaf panel, so that the aim of changing waste into valuable is fulfilled.
The flame-retardant leaf wood chip board has the beneficial effects that the flame-retardant leaf wood chip board is environment-friendly, can be cut and can be nailed like a wood board, and is flame-retardant, formaldehyde-free and simple in structure.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic cross-sectional view of a fire retardant leaf chip board of the present invention.
Fig. 2 is a plan view of a fire retardant foliage chip board.
Detailed Description
In fig. 1, a leaf panel (1), a chip core plate (2) and a leaf panel (3), wherein the leaf panel (1) is arranged below, the chip core plate (2) is arranged in the middle, and the leaf panel (3) is arranged above. The lower part of the leaf panel (1) is exposed outside, the upper part of the leaf panel is adhered to the lower part of the sawdust core plate (2), the lower part of the leaf panel (3) is adhered to the upper part of the sawdust core plate (2), and the upper part of the leaf panel is exposed outside. Because the leaf panels (1), (3) and the sawdust core plate (2) are all manufactured on site by using the environment-friendly adhesive, when the assembly line is sent to the next process to combine the leaf panels (1), (3) and the sawdust core plate (2), the environment-friendly adhesives of the leaf panels (1), (3) and the sawdust core plate (2) which are bonded by the environment-friendly adhesive are not dried, the sawdust core plate (2) is only clamped between the two leaf panels (1), (3) to be extruded into a whole, the environment-friendly adhesive is not needed to be added, only the environment-friendly adhesive is compacted, and after the flame-retardant leaf sawdust plate is manufactured, the leaf panels and the sawdust core plate can be naturally dried or quickly dried by hot air to form a finished product.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The above-described embodiments of the invention are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, and not by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
