Description
Technical field
The invention discloses a kind of preparation methods of moisture-proof resistance to stamp corrugated paper, belong to corrugated paper preparing technical field.
Background technology
Corrugated paper is also known as brown paper, leatheroid, is the common materials of paper packaging box, it is more light than wooden case, and has hardness, greatly
It is small to be easy to cut out, for protecting other packaged products to be not compromised.Corrugated paper can be in the pattern of external printing different color
And word or letter symbol is write, cost is also relatively cheap.General middle-size and small-size corrugated paper box（No any printing, mud yellow）It can be
Daily necessities shop is bought.But, corrugated paper avoid water logging, humidity, it is mouldy, enter water, hand hook etc..Corrugated paper is also sometimes used as handicraft
Material, there are many colors to select for the special corrugated paper for making handicraft, and also someone is with corrugated paper manufacture papery Family Furniture.Currently, most often
Corrugated board is that the cornstarch gluing knot such as brown paper, boxboard or white board is constituted, and is full paper corrugated board；Also have by
Paper from calcium filled plastics is bonded by hot melting way, is calcium-plastic corrugated board.The two has respective advantage and disadvantage, has extensively in packaging field
Using.
Corrugated paper is typically to be fabricated by the hemicellulose wood pulp of broad-leaved piece or Straw Pulp etc., and quantifying for it is general relatively low,
But corrugated paper plays the role of skeleton in the corrugated cardboards after certain temperature and forming under the pressure.In the preparation work of corrugated paper
In skill, generally use：Slurrying → pressure is pumped into steady stock tank → differential water pressures water drenching hanging → felt, and suction → vacuum pump dehydration is got rid of thoroughly
The flow scheme designs such as dry → heating drying cylinder drying → finished product sizing cut roll, the process defect are surface sometimes for cost-effective, are adopted
With waste paper water wet-milling it is broken after slurrying, but its water-resistance and resistance to punctures property can be declined, and because on its preparation flow drying cure
Process is shorter, to affect the intensity water content of corrugation paper product.
Corrugated paper is the plate object that the corrugated paper of the waveform formed by sheet lining and by processing by corrugated roller is bonded,
It is generally divided into two class of single wall corrugated board and double-layer corrugated cardboard, and corrugated paper has at low cost, light weight, processes easy, printing adaptation
Property sample it is excellent, storage convenient in carrying the advantages that.Currently, corrugated paper on the market cannot all carry out effective fire-retardant and fire prevention,
In external environment, phenomena such as corrugated paper is easy to that on fire or spontaneous combustion occurs because of fortuitous event again, especially it is in corrugated paper
In the environment of high temperature, even more have it is prodigious be likely to occur corrugated paper combustion phenomena, greatly increase corrugated paper it is safe to use, no
Use conducive to user to corrugated paper.
The problem of corrugated paper generally existing water-resistance difference at present, the corrugated paper intensity after the moisture absorption significantly decline, in addition watt
There is also poor, intensity difference the defects of resistance to puncture property for stupefied hard copy body, and therefore, a kind of moisture-proof resistance to stamp corrugated paper of invention prepares corrugated paper
Technical field has positive effect.
