Abstract
The invention provides a surface water-repellent paper tube. By coating the external layer of a paper tube with a novel paper tube water-repellent coating agent, the water-repellent purpose is achieved. The surface water-repellent paper tube is characterized in that before gluing of a slip of paper, the paper firstly undergoes a coating process, kraft paper at the external surface layer of the paper tube is coated with a paper tube surface water-repellent agent which is composed of paraffin, petroleum resin, an emulsifier, sodium hydroxide and water, and the inner wall of the tube body is coated with a layer of a mixture of paraffin and oil before connection. According to the water-repellent paper tube, damage to the paper tube structure due to water absorption can be avoided. In addition, the polished seamless surface water-repellent paper tube has a smooth and flat surface. Thus, the dustproof purpose can be achieved.
Description
Technical field
The present invention relates to a kind of paper tube of surperficial drying, this drying smears, a kind of Novel paper tube surface of paper tube skin coating is to reach the object of surperficial drying.
Background technology
Some science and technology, electronics manufacturing are because of the relation of procedure for producing, and have special requirement to the paper tube that it uses, surface has to pass through special processing, to reach waterproof, dustless effect.The paper wrapper of general paper tube mostly is brown paper, and the water repellent treatment of brown paper can only be accomplished at most water-fast, and cannot reach drying degree.Although water-fast paper can bear certain moisture, can not destroy paper structure, paper still can absorb water at once, and drying is then form a watertight composition at paper surface, when water spills paper, can not infiltrate paper, and can form droplet shape separately.
Reach drying effect to enable paper tube and have two kinds of methods: one is that paper wrapper inherently can drying, and two is that waterproof material is coated on paper tube surface.But the current domestic brown paper that can reach drying grade is considerably less, generally must be dependent on external import, cost is very high; And general waterproof material is as materials such as OPP, PE, is not easy to paste then on paper tube, does not also meet environmental protection.
Paraffin wax emulsions does not need that heating and melting, film forming are even, spreadability good in use, is easy to and the aqueous solution of other material or emulsion compound use, has safety, the advantage such as efficient, economic easy to use.At paper tube surface coating one deck paraffin wax emulsions, the surface tension on paper tube surface can be reduced, and make it the surface tension being less than water, to reach the object of waterproof.Simple use paraffin wax emulsions carries out water-proofing treatment to paper products, although can improve its water proofing property, effect is not ideal.With the paper products after paraffin wax emulsions process, water resistance makes moderate progress, but paper products surface there will be the situation of bulge, and still have certain moisture-inhibiting phenomenon, waterproof effect is undesirable.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides a kind of paper tube of surperficial drying, by reaching drying object in this kind of Novel paper tube drying smears of paper tube skin coating.
The paper tube of surperficial drying of the present invention, is characterized in that before paper slip not yet gluing, first through being coated with formality together, and coated paper tube-surface dryingagent in paper tube outer surface layer kraft paper strip, and cylinder inboard wall is coated with one deck paraffin and oily mixture before then.
Above-mentioned paper tube drying smears, its component comprises paraffin, Petropols, emulsifying agent, NaOH and water; Each component proportion is: paraffin 3 ~ 5%, Petropols 4 ~ 6%, emulsifying agent 0.2 ~ 0.3%, and all the other are water.
The component of above-mentioned paper tube drying smears can also have NaOH, and its proportioning is 0.2 ~ 0.3%.
In the component of above-mentioned paper tube drying smears, melting point of paraffin wax is 52 ~ 54 DEG C, and Petropols are C9 Petropols, emulsifying agent is the polyalcohols hydrophilic non-ionic emulsifying agent of HLB value more than 10.
The preparation method of concrete paper tube drying smears is, using paraffin as main material, take Petropols as modifier, with polyalcohols Hydrophilic nonionic emulsifying agent for emulsifying agent, be PH conditioning agent with NaOH, take water as decentralized medium, each component proportion presses paraffin 3 ~ 5%, Petropols 4 ~ 6%, emulsifying agent 0.2 ~ 0.3%, NaOH 0.2 ~ 0.3%, all the other are water.Preparation process is, in reactor, add paraffin, Petropols, emulsifying agent by proportioning, heating and melting stirring at low speed makes it mix.Heating part water, to requiring temperature, pours the water of heating into oil phase, rapid stirring, emulsification a period of time, then adds remaining water, cooling discharge.
In preparation process, emulsifying temperature is 80 ~ 85 DEG C, and emulsification times is 20 ~ 25min.NaOH can also be added, adjustment emulsion PH in emulsion process.
Paper tube surface provided by the invention dryingagent, improve the water resistance of paraffin wax emulsions, this paper tube surface dryingagent is coated on paper tube surface, general paper tube can be made to reach drying effect, avoid because water suction causes paper tube structure to destroy, or be coated on the seamless paper tube surface of polishing, dust can be avoided to drop, and surface also can be more smooth.
Accompanying drawing explanation
Fig. 1 is the Making programme figure of the paper tube of a kind of surperficial drying of the present invention.
Fig. 2 is paper tube surface dryingagent Making programme figure in the present invention.
Detailed description of the invention
Below by specific embodiment, technical scheme of the present invention is described further.
The component of embodiment 1 paper tube surface dryingagent
Each component percentage is:
Petropols: 4%;
Paraffin: 3%;
Emulsifying agent: 0.25%;
NaOH: 0.25%;
Water: 92.5%.
This product is milky white solution, and solid content is adjustable, PH=7 ~ 8.
The preparation of embodiment 2 paper tube surface dryingagent
Paper tube surface dryingagent is prepared by the raw material components of embodiment 1 and proportioning.
Preparation process is as indicated with 2: in reactor, add paraffin, Petropols, emulsifying agent and NaOH heating and melting by proportioning and stirring at low speed makes it mix.Heating part water, to requiring temperature, pours the water of heating into oil phase, rapid stirring, emulsification a period of time, then adds remaining water, cooling discharge.Emulsifying temperature is 80 ~ 85 DEG C, and emulsification times is 20 ~ 25min.
The manufacturing process of the paper tube of the surperficial drying of embodiment 3
In the present invention, the preparation method of the paper tube of surperficial drying as shown in Figure 1, mainly comprises cut paper, paper slip coating, oven dry, gluing, pipe crimping and sequent surface process.The preparation method of the paper tube of surperficial drying of the present invention is substantially identical with the production method of general paper tube.Just before paper slip not yet gluing, first through being coated with formality together, coated paper tube-surface dryingagent in paper tube outer surface layer kraft paper strip.Among the dryingagent side of being put in, paper tube surface basin, there is a big roller square basin inside, and after roller running, paper tube surface dryingagent is taken up by roller, right Hou paper slip is passed by roller, and just coating is got on, and coating can only be coated with one side, because glue is water-based, just cannot gluing after the dryingagent of coated paper tube surface.In addition, the base stock of paper tube and the tube wall of internal diameter, before then, can follow oily mixture by last layer paraffin, the mode oiled is the same with the mode of coated paper tube-surface dryingagent, and its effect, mainly when pipe crimping, plays lubrication roll bar, be convenient to the effect of pipe, also play the effect of waterproof simultaneously.
