Description

A kind of corrugated board
Technical field
The present invention relates to board applications, and in particular to a kind of corrugated board.
Background technique
Corrugated board is to process the waveform plate object formed by liner board and by corrugated roller, is generally divided into single corrugation Two class of cardboard and double-layer corrugated cardboard, is divided into: A, five seed type of B, C, E, F according to the size of corrugation.The invention and application of corrugated paper There is more than 100 years history, at low cost, light weight, processing is easy, intensity is big, printing adaptability sample is excellent, storage convenient in carrying The advantages that.
Packaging material is one of the major function of packaging to the protectiveness of built-in amount of substance, and inner packing is even more to protect to commodity Shield property plays the role of vital.
Corrugated board is the adherend of a multilayer, it is at least made of one layer of waveform core layer and a layer paperboard.Corrugation Cardboard has very high mechanical strength, can to being fallen by the collision in cargo handling process and falling, mainly for the manufacture of carton and The outer packing of delicate articles.
Currently, corrugated board is mainly made of fibrous web, it is easy the shadow by external environmental factors such as humidity, temperature It rings.In the higher environment of some temperature, corrugated board is easy to conduct the heat of absorption to packaging article, indirectly Reduce the quality of article；And when corrugated board directly meets with open fire, then it is easy to happen combustion phenomena, directly destroys institute The article of packaging, brings economic loss.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, a kind of corrugated board is provided.
Technical solution: to achieve the above object, the present invention provides a kind of corrugated board, including cardboard matrix, with parts by weight Component meter, the cardboard matrix include 100 parts of paper pulp, 4-6 parts of polyglycolic acid, 2-3 parts of cationic polyacrylamide, aoxidize alkane 5-10 parts of base amine polyoxyethylene ether, 1-2 parts of chitosan, 1-2 parts of thickener, 20-30 parts of deionized water；The cardboard matrix surface Equipped with thermoplastic elastomer (TPE), the thermoplastic elastomer (TPE) is equipped with nano titanic oxide sol layer, and the thermoplastic elastomer (TPE) is logical It is compounded in cardboard matrix after pressing technology while hot, the thermoplastic elastomer (TPE) and nano titanic oxide sol layer pass through PU glue Bonding.
Be further improved, the thermoplastic elastomer by 50 DEG C of -60 DEG C of melt extrusions of vulcanization screw rod, direct membrane at Type presses molding thermoplastic elastomer by knurling rolls and rubber rollers with cardboard matrix while hot, then cooling through chill roll, Winding obtains semi-finished product.
It being further improved, the cardboard matrix include 100 parts of paper pulp, and 5 parts of polyglycolic acid, cationic polyacrylamide 2.5 Part, 7.5 parts of oxidation of alkyl amine polyoxyethylene ether, 1.5 parts of chitosan, 1.5 parts of thickener, 25 parts of deionized water.
It being further improved, the cardboard matrix include 100 parts of paper pulp, and 4 parts of polyglycolic acid, 2 parts of cationic polyacrylamide, 5 parts of oxidation of alkyl amine polyoxyethylene ether, 1 part of chitosan, 1 part of thickener, 20 parts of deionized water.
It being further improved, the cardboard matrix include 100 parts of paper pulp, and 6 parts of polyglycolic acid, 3 parts of cationic polyacrylamide, 10 parts of oxidation of alkyl amine polyoxyethylene ether, 2 parts of chitosan, 2 parts of thickener, 30 parts of deionized water.
The beneficial effects of the present invention are:
It is strong by the tear-proof that fabric entirety on the one hand can be improved in double-deck overlay film of cardboard matrix surface progress in the present invention Degree and crocking resistance, and the use of glue and plasticizer is reduced, Environmental Safety, on the other hand, the titanium dioxide of Nano grade The coating of titanium sol layer enables the surface of fabric to have clean surfaces net work, it is possible to reduce wash number, while having preferably Waterproofness；
Cardboard matrix are reinforced using composite construction, and there are the strong substrate base of crushing resistance compound thermoplastic elastomers again, just In thermoplastic elastomer (TPE) stabilization be compounded on matrix, while thermoplastic elastomer (TPE) have stronger compressive property, elastic property, because This further enhances corrugated board intensity and elasticity, ultimate strength Jing Xiang≤2500N, Wei Xiang≤2800N, tearing brute force through to ≤ 500N, Wei Xiang≤300N, waterproof performance are good.
