Abstract
A board is composed of at least one paper layer, two fibre layers at both sides of paper layer, and two surface layers. It is made from waste natural fibrous materials through treating, drying, mixing, grinding, adding adhesive, making fibre layer, coating adhesive on both surfaces of paper layer made of reclaimed paper, applying fibre layer to both sides of paper layer, and hot pressing. Its advantages are high strength and toughness, and environmental protection.
Description
The present invention relates to a kind of sheet material and manufacture method thereof.
Timber is the indispensable valuable source of human survival, and architectural decoration, indoor furniture, transportation and packing etc. all use timber to be main material such as.Owing to the forest reserves are denudated in a large number and have been destroyed the Nature ecological environment, make the environment of the earth more and more abominable, this problem is subjected to the attention of government and environmental administration day by day, and forbids the mankind that timber is denuded, and causes taking of timber more and more difficult.Again, discarded object because of tool natural plant fibres such as wood chip, bagasse, husk, straw, alfas, usually do not have recycling property, so handle in the burning mode mostly, the black smoke that is produced when handling waste combustion by this way can cause air pollution, if then cause the vehicle driver visual field not good in that road is other, even get into an accident and cause serious consequence.
In view of this, main purpose of the present invention is, a kind of sheet material and manufacture method thereof are provided, and it can effectively utilize the discarded object of including natural fibers and reclaim paper and make sheet material, has the environmental pollution of minimizing and promotes environmental protection function.
Sheet material of the present invention is to adopt following technical scheme:
A kind of sheet material is characterized in that, comprises a ply of paper, two fibrages at least, is the both sides of being located at described ply of paper respectively, and two surface layers, is located at described fibrolaminar both sides respectively.
Aforesaid sheet material, wherein this fibrage is made with urea formadehyde glue for discarded wood chip, bagasse, husk, straw, alfa etc. are natural fiber mixed.
The manufacture method of sheet material of the present invention is to adopt following technical scheme:
Get a raw material, this raw material is wood chip, bagasse, husk, straw, the alfa the like waste with natural fiber, these raw materials are ground after mixing through arrangement, drying, pulverizing, grind the back and form a powder, again these powders are carried out simple screening and separate to form thick, thin two kinds of powders, again fine powder material is layed in the outermost layer of material disc and forms a surface layer; Other adds jelly and stirs in the meal material, be overlying on the fine powder material surface layer, and form a fibrage;
Getting a ply of paper, is to be primary raw material to reclaim paper, in the outer surface gluing of ply of paper;
One surface layer and fibrage are located at the both sides of ply of paper, and make its joint, cut then in disposable HTHP mode.
The present invention can effectively utilize the discarded object of including natural fibers and reclaim paper and make sheet material, has the environmental pollution of minimizing and promotes environmental protection function.
For further understanding technology contents of the present invention, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:
Fig. 1 is the combination schematic perspective view of sheet material of the present invention.
Fig. 2 is the profile of sheet material of the present invention.
Fig. 3, Fig. 4 are the present invention's schematic flow sheets of getting the raw materials ready.
See also Figure 1 and Figure 2, sheet material of the present invention is to take that to reclaim the discarded object that paper and wood chip, bagasse, husk, straw, alfa etc. contain natural plant fibre be primary raw material, and the manufacture method of this sheet material comprises the following steps:
One, obtains raw material
At first, obtain raw material, see also shown in Figure 3, this raw material is main raw material for discarded wood chip, bagasse, husk, straw, alfa etc. have natural plant fibre, these materials are ground after mixing through arrangement, drying, pulverizing again, then form a powder after the grinding, then these powders are given the simple screening separation and make thick, the thin two kinds of powders of its formation.
Two, powder is handled and is produced fibrage
After obtaining thick, fine powder material, fine powder material is layed in the outermost layer of hot press implements charging tray and forms a surface layer; Other adds urea formadehyde glue and stirs in this meal material, be overlying on the fine powder material surface layer, so forms a fibrage.
Three, cover fibrage up and down what reclaim ply of paper
After producing fibrage, reclaim ply of paper with one and be layed on this fibrage, this upper and lower surface of recoverys ply of paper is all given sticky gluing, again fibrage oppositely is layed on the recovery ply of paper, like this then finish the preparation of material.
Four, the heating pressurization cuts
After material is ready to complete, imposes the one-time heating pressurization with hot press surface layer, fibrage and recovery ply of paper are bonded with each other, can make a sheet material after fumigating with steam simultaneously, again sheet material is cut into standard specification and promptly finish sheet material of the present invention.
Sheet material of the present invention, it includes one and reclaims ply of paper 10, the both sides of this recovery ply of paper 10 are provided with a fibrage 11, in the lateral surface of this fibrage 11 then is a surface layer 12 of being made by fine powder material, the surface layer 12 that this fine powder material is made because of with fibrage 11 mutually pressing stick together, so it can increase the smoothness and the density of sheet material.This plate construction has following effect:
1, primary raw material is to make with the husk, the straw the like waste that contain natural plant fibre, its sufficient material source and cheap, can not produce pollutant such as waste gas, waste water again because of manufacture process and produce last reject product and handle simply, can not cause secondary pollution, have high environmental protection function.
2, has high tenacity and high strength.Usually a lot of sheet materials all have intensity and lack toughness, can only reduce the deficiency of artificial plate toughness with thickness, have both increased cost, again the post-production of sheet material are caused the difficulty of operation.Sheet material of the present invention can be suitable for different purposes, can select to reclaim the number or the filametntary fineness degree of ply of paper.
3, have moisture resistance,,, have extremely strong moisture resistance after the urea formadehyde glue drying again through 1500 tons of hot press once hot pressings because of primary raw material is with after urea formadehyde glue spray mixes, and sheet material free from insect pests danger.
Sheet material of the present invention can be used for architectural decoration, indoor furniture, transportation and packing, pallet, cremate with coffin etc.
Claims (3)
