Abstract
The present invention relates to a manufacture method of a package buffering material. Corn straw pitch which is pulverized into granules which pass through a sieve with 5 meshes and are trapped between sieves with 40 meshes is used as a raw material, and steamed and boiled waste liquid which is used for pulping and making paper and is evaporated and concentrated into a solid substance of which the content reaches 20% to 70% is used as a bonding agent. The mass ratio of corn straw pith to the solid content quantity of waste liquid is 1:0.1 to 1.0, and a mixture is distributed in a mould cavity of a mould, is moulded and formed at normal temperature under the conditions that pressure intensity is 0.02 to 0.5MPa, and the pressurization time is at least 10 seconds, is demoulded and is dried to 6 to 12% of water content at the temperature of 60 to 200 DEG C. The present invention comprehensively uses sanitized corn straws, the cost of the package buffering material is very low, and the pollution of the waste liquid for pulping is eliminated. The product has the advantages of low relative density and better strength and condensibility and can completely satisfy the requirement of various packages for the buffering material.
Description
Technical field
What the present invention relates to is the comprehensive utilization field of agricultural production stalk, particularly produces the wrapping material technology.
Background technology
Current, aspect corn and broomcorn straw comprehensive utilization, reasonable approach is that stalk is separated into leaf, stalk skin and stalk marrow, is used respectively then, such as leaf being made feed or being gone back the field, with stalk leather slurry, produces package buffer material etc. with the stalk marrow.
Do package buffer material with the cornstalk marrow, the invention disclosed patent roughly can be divided into two classes.The technology of one class such as CN 94116536.1 (Northwest Agricultural University) patent, be after the stalk marrow is pulverized, bleached, be dried to and moisturely be divided into 12%, it is hot-forming in the mould to mat formation, and do not adopt tackiness agent, so intensity is limited, be not suitable as the package buffer material of large article, in addition maize straw being required must be air-dry month of fresh straw, can not be impure, and can not have and go mouldy.This is for the very strong agricultural crop straw of seasonality, brings obviously for the application of stalk and seriously influences.From whole process of production, its production discontinuous and manual operations are more, only are applicable to individual workship.Another kind of is the production method that adopts tackiness agent, as CN 88105118.7 (the Siping City Zhang Guangrui of Jilin Province), CN 99115768.0 (Xian City, Shanxi Province Wu Zhi is firm), CN 99115870.9 (Zhou Mouzhi of Xi'an University of Architecture and Technology etc.), CN 99113950.x (Shanghai Xu Hua), all be to adopt tackiness agent to mix with the stalk marrow, shaping and drying then, its tackiness agent adopts starch, polyvinyl alcohol etc. mostly, and other auxiliary agent of interpolation part as required, the consumption of tackiness agent is all bigger, has significantly improved production cost.
Summary of the invention
Defective at prior art exists the purpose of this invention is to provide a kind of cooking waste liquor of pulping and paper-making that utilizes and is tackiness agent, the stalk marrow is bondd make package buffer material, reduces the production method of the cost of package buffer material significantly.
Technical scheme of the present invention is to implement like this:
(1) adopts mechanical separation device that maize straw is separated into leaf, stalk skin and stalk marrow, the stalk skin is cut into the tablet of 25～30mm, be used for slurrying; The stalk marrow is ground into granularity between 5 orders～40 orders, is used to produce package buffer material.
(2) cooking waste liquor of employing slurrying is concentrated into 20～70% concentration with waste liquid, as the tackiness agent of package buffer material.
(3) granulous stalk marrow is mixed with the mass ratio of spissated pulping waste liquor by 1: 0.1～1.0 (in solid substances), in mixing machine, stir.
(4) the mixture branch is installed in the forming mould, at normal temperatures with the pressure compressed moulding of 0.02～0.5MPa.
(5) demoulding is placed on drying in the tunnel drier, 80～200 ℃ of drying temperatures.
(6), can be coated with water-resisting agent on the surface according to different product requirements.
Following processing condition are more superior in the above-mentioned after deliberation technology: the cooking waste liquor evaporation concentration of pulping and paper-making, make solid contents be reached for 40%～60%, consider from the angle of comprehensive utilization, especially with the cooking waste liquor of cornstalk skin alkalescence and monosulfite pulping for well; The mass ratio of the solid substance amount of cornstalk marrow and waste liquid is 1: 0.3～0.8; Drying temperature is 120～150 ℃.
Advantage compared with prior art of the present invention is: with the isolated by product stalk of pulping raw material marrow is raw material, waste liquid with slurrying is a tackiness agent, realized innoxious maize straw comprehensive utilization, paper pulp and package buffer material all have higher value added, wherein the cost of package buffer material is cheap unusually, and eliminated the pollution of pulping waste liquor, make changing waste into resources; Package buffer material itself is free from environmental pollution, can natural degradation.In addition, this package buffer material relative density of the present invention is low, have intensity and compressibility preferably, can satisfy the requirement of various packings for cushioning material fully.China produces about 2.2 hundred million tons of maize straw per year, if utilization ratio can reach 50%, can have 1.1 hundred million tons to be used for papermaking.General stalk skin content is 35% of full stalk, and the ratio of stalk marrow is 15%, can have an appointment 1,600 ten thousand tons for producing more than 2,000 ten thousand tons of package buffer materials.Therefore remarkable economical and social benefit are arranged.
Embodiment
Example one: get by 6 orders and be retained in stalk marrow on 10 mesh sieves, the ratio according to stalk marrow and waste liquid solid substance than 1: 0.6, the adding solid concentration is 40% waste liquid, stirs to make it to mix, in the cube of manually packing into the mould, apply the pressure of 0.2MPa, pressurizeed for 15 seconds, this moment, material was compressed into piece, the demoulding is placed in the moisture eliminator, at 150 ℃ of dry 20min, promptly make package buffer material, the relative density of material is 0.2415g/cm
3, have intensity and compressibility preferably.
Example two: get by 20 orders and be retained in stalk marrow on 40 mesh sieves, the ratio according to stalk marrow and waste liquid solid substance than 1: 0.5, the adding solid concentration is 40% waste liquid, stirs to make it to mix, in the cube of manually packing into the mould, apply the pressure of 0.15MPa, pressurizeed for 15 seconds, this moment, material was compressed into piece, the demoulding is placed in the moisture eliminator, at 150 ℃ of dry 20min, promptly make package buffer material, the relative density of material is 0.1826g/cm
3, have intensity and compressibility preferably.
