A kind of production technology of waterproof corrugated paper
Technical field
The present invention relates to field of papermaking, specifically a kind of production technology of waterproof corrugated paper.
Background technology
Corrugated board is to be bonded by viscose glue by facial tissue, inner paper, core paper and the corrugated paper that is processed into waveform corrugation, manyTo be applied to prepare carton, with packed and transported product. It in use faces maximum problems, is exactly to occur by rain unavoidablyDrench or water logging, and the situation that causes the bond properties between its each layer of ply of paper to decline, the ply of paper of cardboard becomes and easily peels off, therebyCause cardboard to be scrapped useless.
Summary of the invention
For addressing the above problem, the invention provides a kind of production technology of waterproof corrugated paper.
The production technology of waterproof corrugated paper of the present invention, by traditional handicraft by facial tissue, inner paper, core paper be processed into waveformThe corrugated paper of corrugation, by the bonding corrugated board of making of viscose glue, is characterized in that, described viscose glue is by getting 20-30 DEG C of water 420Weight portion, starch 26 weight portions, liquid caustic soda 33 weight portions stir 300 seconds, 700 weight portions that then continue to add water, starch 295 weightPart, then stir after 100 seconds, interpolation auxiliary agent 75 weight portions, tackifier 20 weight portions, borax 4 weight portions mix and make;
Wherein, described auxiliary agent is that Lianyun Harbour Lv Yuan adhesive Co., Ltd produces Lv garden water resistant reinforcing anti-blushing agent; Described tackifyAgent was clayed into power respectively for getting longan seed (being longan fruit stone), Receptaculum Fici Pumilae, sesame, calcite, attapulgite clay, diatomiteFor subsequent use after 200 mesh sieves, then by longan seed powder 10 weight portions, Receptaculum Fici Pumilae powder 10 weight portions, sesame powder 2 weight portions, sideSeparate stone powder 20 weight portions, attapulgite clay powder 20 weight portions, diatomite powder 5 weight portions, water 100 weight portions in 100 DEG CWhen mixing infusion to moisture content and still depositing 10-20 weight portion, naturally cool to normal temperature (20-35 DEG C) and make that (prepared by tackifierWeight portion in journey can be different from the weight portion radix in viscose glue preparation process).
The auxiliary agent that the present invention adopts and the formula of tackifier, the science of having passed through is selected and allotment meticulously, and the viscose glue of making is largeWidth has improved the various performances of cardboard, and after cardboard soaks for a long time or drenches with rain, still can make cardboard keep after dryIts original proterties is substantially constant.
The corrugated board that the present invention makes, has high performance, and after immersion or drenching with rain, it is naturally dried or is driedDry, cardboard can not be out of shape, and between ply of paper, can not depart from, and has improved the serviceability of cardboard, has further promoted the value of cardboard.
Detailed description of the invention
By the following examples and comparative example the present invention will be described in detail.
Embodiment: the production technology of waterproof corrugated paper, by traditional handicraft by facial tissue, inner paper, core paper be processed into waveformThe corrugated paper of corrugation, by the bonding corrugated board of making of viscose glue, is characterized in that, described viscose glue is by getting 25 DEG C of water 420 public affairs33 kilograms of jin, 26 kilograms of starch, liquid caustic soda stir 300 seconds, then continue to add water 295 kilograms of 700 kilograms, starch, then stir 100 secondsAfter, add 4 kilograms of 75 kilograms of auxiliary agents, 20 kilograms of tackifier, borax and mix and make;
Wherein, described auxiliary agent is that Lianyun Harbour Lv Yuan adhesive Co., Ltd produces Lv garden water resistant reinforcing anti-blushing agent; Described tackifyAgent for get longan seed, Receptaculum Fici Pumilae, sesame, calcite, attapulgite clay, diatomite clayed into power respectively for subsequent use after 200 mesh sieves,Then by 10 kilograms, longan seed powder, 10 kilograms, Receptaculum Fici Pumilae powder, 2 kilograms, sesame powder, 20 kilograms, calcite powder, concave convex rod100 kilograms of 20 kilograms of clay powders, 5 kilograms of diatomite powders, water in the time that 100 DEG C mix infusion to moisture content and still deposit 15 kilograms, fromSo being cooled to 30 DEG C makes.
The cardboard that the present embodiment is made, after immersion or drenching with rain, naturally dries it or dries, and cardboard can not be out of shape, ply of paperBetween can not depart from.
Comparative example 1: different from embodiment, do not add auxiliary agent, make the cardboard of comparative example 1.
Comparative example 2: different from embodiment, do not add longan seed, Receptaculum Fici Pumilae, sesame, make the paper of comparative example 2Plate.
Comparative example 3: different from embodiment, do not add calcite, attapulgite clay, diatomite, make comparative example 3Cardboard.
Comparative example 4: different from embodiment, in the preparation of tackifier, not in 100 DEG C mix infusion to moisture content stillDeposit 15 kilograms, mix but directly add 15 kilograms, water, make the cardboard of comparative example 4.
Comparative example 5: different from embodiment, the viscose glue adopting is the Xiong County Ou Nasen adhesive system of selling on the marketMake the gloomy ONS-200 model of the Ou Na viscose glue of Co., Ltd, make the cardboard of comparative example 5.
The cardboard of embodiment and comparative example 1-4 is under equal conditions detected, obtains experimental result as follows:
Cardboard ply of paper is peeled off ring crush index (Nm/g)
Before before immersion, immersion is dried in immersion after 24 hours, immersion was dried after 24 hours
Embodiment cannot peel off and cannot peel off 10.510.3
Comparative example 1 cannot be peeled off substantially peelable, and 6.14.5 still cannot be peeled off in part ply of paper contact site
Comparative example 2 cannot be peeled off substantially peelable, and 5.64.3 still cannot be peeled off in part ply of paper contact site
Comparative example 3 cannot be peeled off substantially peelable, and 5.84.8 still cannot be peeled off in part ply of paper contact site
Comparative example 4 cannot be peeled off substantially peelable, and 7.05.3 still cannot be peeled off in part ply of paper contact site
Comparative example 5 cannot be peeled off and can peel off easily, and between ply of paper part contact site automatic trip from 6.24.1
Can find out the cardboard that paperboard properties that the embodiment of the present invention makes adopts conventional viscose glue to make, in performance, have greatly and changeKind, and dry after long-time immersion, the performance of cardboard there is no reduction before immersion.
