Description

The oriented structure paper made of obsolete material
Technical field
The present invention provide it is a kind of with obsolete material make oriented structure paper, in particular to a kind of new packaging material, More particularly to oriented structure mode makes paper.
Background technique
In recent years, with the development of global logistics and traffic transport industry, more and more packaging materials are needed, are such as packed Paper, packaging bag etc..China is manufacturing powerhouse, is counted according to packaging association, the world, what China's wrapping paper industry in 2011 was occupied Market scale has just reached 150,000,000,000 dollars, Zhan Quanqiu 22.5%.However, since China's packaging industry more falls behind, it is a large amount of useless Packaging material is abandoned to environment nocuousness, the positive green of packaging material, environmentally friendly direction are developed.
China is large agricultural country, however is limited by self-growth level, although some agricultural wastes can be used for making Particieboard, but still have a large amount of agricultural wastes because that cannot efficiently use every year, there is artificial the phenomenon that burning, generates a large amount of Harmful exhaust, both waste resource, also compromise residents ' health, polluted atmospheric environment.China is also manufacturing powerhouse, often Fabricate a large amount of wrapping paper year, however discarded wrapping paper but cannot get effective recycling, largely discard wrapping paper It is artificial to abandon, resource is greatly wasted, ring environment is also broken, violates circular economy, the policy of energy-saving and emission-reduction and theory.At present Wrapping paper lead to Wood in Common Use be process, the processing use of China's timber resource shortage, single timber is unfavorable for sustainable development Exhibition, also increases manufacturing cost, these problems are urgently to be resolved.
Summary of the invention
For state of the art, the technical problem to be solved by the present invention is with rice straw, straw, cotton linter, wood shavings wood Material, bamboo, shredded paper are raw material, the paper with oriented structure are made by way of pre-processing and orienting bonding, production process can edge The technology and equipment bonded with pulping and paper-making or oriented structure, to solve the above-mentioned wasting of resources and problem of environmental pollution.
The technical solution adopted by the present invention are as follows: oriented structure paper has three-decker, is followed successively by damp-proof wear-resistant from top to bottom Layer 1, structured base layer 2 and damp-proof wear-resistant layer 3, wherein damp-proof wear-resistant layer 1 is identical with 3 material of damp-proof wear-resistant layer；Structured base layer 2 is by rice , in bamboo one or more of oriented by a kind of sizing agent bonds for stalk, straw, wood shavings wood；Up and down the two of structured base layer 2 The sizing agent covering of another bonding in face, can also be by by pretreated shredded paper, cotton linter at damp-proof wear-resistant layer 1 and 3 One or two by the sizing agent orientation bond.
Raw material rice straw, straw, wood shavings timber, bamboo, shredded paper, cotton linter are needed by pretreatment, comprising to raw materials used Cutting and screening and the selectively removing to ash content, wax and water-soluble substances；It is required that pretreated raw material length In 10mm between 50mm, width is in 0.2mm between 10mm.
One or more of rice straw, straw, wood shavings timber, bamboo raw material are pre-processed, are oriented with sizing agent It is bonded to structured base layer 2；Then one or both of shredded paper and cotton linter are pre-processed, respectively with another sizing agent Damp-proof wear-resistant layer 1 and damp-proof wear-resistant layer 3 are bonded in structured base layer upper and lower surface orientation.
The sizing agent that structured base layer 2 uses is the mixing of Lauxite (UF) and methyl diphenylene diisocyanate (MDI) Glue UF-MDI, wherein MDI mass content is 5% to 30%；The sizing agent that damp-proof wear-resistant layer 1 and 3 uses is polyvinyl alcohol (PVA)。
The thickness of structured base layer is in 3mm between 8mm, and the thickness of damp-proof wear-resistant layer is in 1mm between 3mm.
Effect of the invention are as follows: waste resource is transformed into have excellent performance and environmental protection the orientation knot with three-decker Structure paper opens new application for waste materials, advantageously accounts for the wasting of resources and problem of environmental pollution.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Embodiment 1: using rice straw and straw as raw material, being carried out break process, select length 30mm to 40mm, wide The material in 3mm to 5mm is spent, with the epoxy glue UF-MDI (MDI of Lauxite (UF) and methyl diphenylene diisocyanate (MDI) Mass content 15%, resin added 7%) it is glued, is orienting spreading, hot-forming.Gained cardboard is single layer, and thickness is in 5mm Left and right has certain structural strength, and burst size of methanal is lower than 9mg (100g)-1, can be used as summer sleeping mat or Packaging Box.
Embodiment 2: as shown in Figure 1, being a kind of wrapping paper, having three-decker, and the 1st layer and the 3rd layer is damp-proof wear-resistant layer, 2nd layer is wood shavings layer.Embodiment are as follows:
1) wood shavings layer paperboard 2 is first made, using Wheat Straw and wood shavings timber as raw material, through broken, screening, length is obtained and exists 30mm to 50mm, width synthesizes the single ply board of oriented structure in 2mm to the material between 10mm according to the method for embodiment 1, thick Degree is in 5mm or so.
2) using polyvinyl alcohol (PVA) powder as adhesive, two surfaces difference of the cardboard obtained by previous step is hot-forming.
Embodiment 3: as shown in Figure 1, being a kind of wrapping paper, having three-decker, and the 1st layer and the 3rd layer is shredded paper layer, and the 2nd Layer is wood shavings layer.Embodiment are as follows:
1) wood shavings layer paperboard 2 is first made, using Wheat Straw and wood shavings timber as raw material, through broken, screening, length is obtained and exists 30mm to 50mm, width synthesizes the single ply board of oriented structure in 2mm to the material between 10mm according to the method for embodiment 1, thick Degree is in 5mm or so.
2) using shredded paper as raw material, more broken material is obtained through broken, sorting, using polyvinyl alcohol (PVA) powder as adhesive, Two surfaces difference of cardboard obtained by previous step is hot-forming.The three-decker cardboard overall thickness about 9mm of formation, the 1st layer and the 3rd Layer is shredded paper layer, every layer with a thickness of 2mm or so, middle layer 2 is wood shavings layer, with a thickness of 5mm.
Shredded paper layer in this example makees sizing agent using polyvinyl alcohol, have smooth, oil resistant, can natural degradation, toxicity it is low The features such as；Sizing agent used in wood shavings layer is the epoxy glue UF- of Lauxite (UF) and methyl diphenylene diisocyanate (MDI) MDI has very high adhesion strength, and raw material itself has certain folding resistance, is formed by oriented structure paper layer knot with higher Structure intensity；The advantages of this example has bonded shredded paper layer on wood shavings layer two sides, and gained cardboard is simultaneously and there are two types of paper layers, has higher Structural strength and bond strength, surface is smooth, oil resistivity is good, can block gas infiltration, is environment-protecting and non-poisonous, alternative brown paper is made For the use of wrapping paper boxboard.
