[Industrial Application Field] The present invention relates to sheets for manufacturing containers such as boxes or bags that prevent slipping, and in particular, sheets that are coated with an anti-slip agent before forming boxes, bags, or pasting onto cardboard. This invention relates to a container sheet. [Prior Art] In order to prevent boxes or bags stacked on pallets from shifting, it has been conventional practice to coat boxes or bags with an anti-slip agent. Two methods are known: one in which a soft resin or rubber is coated to prevent slippage due to its tackiness, and the other is a method in which inorganic particles are coated together with a binder. Specifically, (1) a method of applying and drying a solution or dispersion of a soft resin or rubber, (2) in addition to the above, mixing expandable hollow particles made of a soft synthetic resin,
(3) a method in which inorganic particles with large irregularities are applied and dried together with a binder. (1)
As an example, JP-A-48-60090 discloses a method of coating corrugated cardboard boxes with atactic polypropylene or ethylene/vinyl acetate copolymer. As an example of (2), Japanese Utility Model Application Publication No. 57-29323 discloses an anti-slip paper in which a foamable paint is layered on paper or a sheet, and Japanese Utility Model Application Publication No. 60-21419 discloses a non-slip paper in which a foamable paint is layered on a paper or sheet. A technique has been disclosed in which hollow spheres of flexible resin are dispersed, applied, and dried, and the elastic effect of the hollow spheres significantly increases the anti-slip effect. [Problem to be solved by the invention] In the conventional method, coating and drying were usually performed after making a box or bag, but the printing process on atoms,
Alternatively, if the coating can be applied at a stage prior to container forming (the steps of box making and bag making are collectively referred to as container forming) such as in the papermaking process, the process can be simplified and energy resources can be saved. However, if the coating is applied at the atomic stage before the container is formed, the coated material will become sticky due to the heat received during box making, bag making, or corrugated board lamination in methods (1) and (2). This may cause problems such as adhesion to rolls or belts. In particular, the method (2) has the drawback that the hollow particles of the soft polymer foam significantly, impairing the cosmetic appearance of the print. Furthermore, even if heat is not necessarily applied in the post-process, blocking is likely to occur when winding kraft paper for bags coated with adhesive resin, for example. In method (3), if a soft binder is used, there will be the same drawbacks as above, but if a hard resin (with a relatively high softening point) is used as the binder and the unevenness of the inorganic particles is used to prevent slipping, Although this eliminates the problem of sticky substances adhering, there is a problem that the particles may damage the rolls in the subsequent process or the particles may peel off. If the binder does not have tatty properties, a large amount of uneven particles are required to prevent slippage, which also poses a problem in that the cosmetic appearance of printing is impaired. Therefore, when it is rolled up, it does not block, there is no need to worry about sticky substances adhering to it due to heat in the post-process, particles will not peel off or damage the roll, and furthermore, the cosmetic appearance of printing will not be affected. It has been desired to develop a sheet for containers that has excellent anti-slip properties. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present inventors conducted intensive research and as a result, completed the present invention. The composition of the container sheet having anti-slip properties of the present invention consists of (a) a mixture of transparent inorganic or organic particles with a particle size of 2 μm or less and a flow initiation temperature of 100°C or higher and a synthetic resin binder; ) Consists of a layer containing expandable hollow particles of synthetic resin with a softening point of 100°C or higher. The hollow particles do not necessarily need to be foamed at the stage of forming the container sheet of the present invention, and may be partially or completely foamed. Examples of the transparent inorganic particles used in the present invention include various types of silica. In addition, as transparent organic particles,
For example, synthetic resin powder such as polystyrene is used. The layer imparting anti-slip properties of the present invention is usually a coated layer using various coaters, but may also be a layer formed by impregnation, spraying, etc. Transparent inorganic or organic fine particles make up 10% of the total coating layer by weight in order to create many minute irregularities on the surface of the coating layer and prevent blocking and slipping.
This is necessary, and in order not to impair the beauty of the printing applied to the lower layer, it is necessary to keep it below 40%. It is also necessary to prevent the entire coating layer from flowing at high temperatures and to prevent irregularities caused by foaming of hollow particles from flowing away. The synthetic resin binder must not flow at the highest temperature of the entire process in which the sheets of the present invention are manufactured and used. Normally, the drying process for coating and printing is at a low temperature of around 100℃, and at a high temperature of 140℃.
It is about ℃. In addition, even if the surface temperature of the paper is high when laminating the double backer side of the cardboard,
It is about ℃. Therefore, a coating layer that does not flow at least at about 100°C is required. The flow during use must be evaluated not only for the resin alone but also for the mixture of particles. The state in which thermoplastic resin changes with temperature can be divided into four regions: glassy region, glass transition region, rubbery region, and flow region.The resin that can be used in the present invention is mixed with fine particles at a temperature of 10°C or higher, Preferably
It should be in the rubbery region at a temperature somewhere between 100 and 160 degrees Celsius. The location of the four regions varies depending on the time scale of the measurement, but since we are concerned with adhesion during normal work, dynamic viscoelasticity is measured on a time scale of about 0.1 to 1 second while increasing the temperature. In the measurement, the relaxation modulus was 10 6
~ 107 dyn/ cm2 , the temperature change is small,
The region before flow is defined as a rubbery region.
The temperature at which the relaxation modulus suddenly decreases to 10 6 or less is defined as the flow start temperature of the present invention. Many resins themselves have a rubbery temperature range between 100 and 160°C, but such resins form a hard film at room temperature and are not preferred as anti-slip agents. You need to choose something that is soft even at room temperature. Therefore, resins with a glass transition temperature of -30°C to 10°C are crosslinked in units of monomers, at a ratio of about 1 in 50 to 100, to maintain a rubbery region without causing flow even at high temperatures. It must be something that has been done. Such examples include polymethyl acrylate,
Polyethyl acrylate, styrene/butyl acrylate copolymer (styrene 50% or less), vinyl acetate/butyl acrylate copolymer (vinyl acetate 80%)
% or less), and acrylic polymers such as methyl methacrylate/ethyl acrylate copolymer (50% or more ethyl acrylate), which are copolymerized with functional groups capable of causing a crosslinking reaction at a monomer ratio of 0.5 to 1.5%. Examples of the above-mentioned functional groups include epoxide groups, acid anhydrides, amino groups, carboxyl groups, hydroxyl groups, amide groups, isocyanate groups, etc., and if a set of mutually compatible groups is selected and used, good. In addition, a copolymer such as a polyacrylic ester copolymerized with the above-mentioned reactive monomer can be bonded to the surface of the silica fine particles using a silane coupling agent, so that the silica fine particles can function as a crosslinking agent. You can also coat the glass fiber surface with Ticl 4
When treated and activated with a Lewis acid such as or Sncl 4 ,
There is a method in which cationic polymerization is initiated by a complex between silanol groups on the glass surface and a Lewis acid, and styrene or epoxy resin is graft-polymerized, and this method may be applied to the silica fine particles of the present invention. The amount of synthetic resin binder used is
It accounts for 60 to 90% by weight of the coating layer. The heat-expandable synthetic resin hollow particles used in the present invention are necessary to cause foaming to occur in the sheet of the present invention or at the time of use, to create large irregularities and to provide an anti-slip effect. It is not possible to obtain sufficient anti-slip properties using only the above-described synthetic resin binder and fine particles; for example, in order to obtain a slip slope of 45°, it is necessary to add foamable synthetic resin hollow particles. As synthetic resin expandable hollow particles,
For example, styrene, methacrylic acid ester, acrylonitrile/vinylidene chloride copolymer, etc. are used.
It is necessary to use resin particles with a temperature of 100°C or higher. The softening point here is the recut softening point defined by ASTM-D1525. The particle size of hollow particles is 2~
20 μm is preferable, and the total coating layer contains
An addition amount of 0.5-2% is required. If it is less than 0.5%, the anti-slip effect will be low, and if it is more than 2%, whitening of the printed surface will become noticeable, which is not preferable. The coating amount of the entire coating layer is preferably 1 to 5 g/m 2 based on the total solid weight. The base material used in the present invention may be a material directly used as a container, such as corrugated paperboard, paperboard, or kraft paper, or may be thin printed paper or plastic film. A thin sheet provided with the coating layer of the present invention can then be used by being attached to cardboard. According to research by the present inventors, if an undercoat with a filler such as starch is applied before applying the anti-slip agent of the present invention, the same level of anti-slip agent can be obtained, but the anti-slip agent will be less The results show that the amount of agent applied can be reduced by half, contributing to cost reductions for anti-slip agents. Furthermore, if the coating amount is the same, the anti-slip effect can be further enhanced. [Function] The function of the coating layer that provides the anti-slip properties of the present invention is considered to be as follows. In order to prevent the coated layer from flowing even when heated in the subsequent process, a resin with a high softening point must be used, but such resin does not have an anti-slip effect and will not flow at high temperatures. It is necessary to use a resin that is soft even at low temperatures. Therefore, we used a resin that has a wide temperature range in the rubbery region of the viscoelastic behavior of a polymeric material. In addition, the fine particles create microscopic irregularities, and in conjunction with this,
By generating a small amount of large irregularities, it has become possible to apply the coating without damaging the aesthetic appearance of the print. [Example] Examples of the present invention are shown below. Examples 1 to 4, Comparative Examples 1 to 2 Cardboard base paper with a basis weight of 200 g/m 2 (manufactured by Honshu Paper Co., Ltd.)
PFK200 liner) is printed in 4 colors using a 5-color flexo printing machine, and in the final printing section, 2g/ml of anti-slip agent with the composition shown in Table 1 below is applied to the bottom and top of the cardboard box. 2 m2 was applied and dried in a food dryer at 120°C for 5 seconds. The polyethyl acrylate binder used in the formulation is a copolymer obtained by mixing 1:1 emulsion of polyethyl acrylate containing 1 mol% of glycidyl alkrylate and polyethyl methacrylate containing 1 mol% of dimethylaminoethyl methacrylate. was used.

[Table] As is clear from the results in Tables 1 and 2, all of the examples of the present invention in which 20 to 30% by weight of inorganic particles and 0.5 to 2% by weight of hollow particles were dispersed in an acrylic ester binder were slippery. It is effective when the inclination angle exceeds 40° after 10 repetitions, which is considered a passing score for the anti-slip effect, but both Comparative Example 1, which does not contain expandable hollow particles, and Comparative Example 2, which contains a small amount of silica, have no anti-slip effect. I can't get it. Anti-slip agents are usually applied entirely or partially to the top and bottom surfaces of boxes, but in the present invention, unlike other anti-slip agents, they are less sticky, so they can be easily applied to the top and bottom surfaces of boxes due to vibrations when loading and transporting them. In order to prevent displacement of adjacent boxes, it is preferable to apply the anti-slip agent of the present invention on the entire surface or part of the side surfaces as well as the top and bottom surfaces. [Effects of the Invention] As described above, the present invention eliminates the wasteful process of applying and drying the conventional anti-slip agent for containers after container manufacturing, and improves the anti-slip property at the stage of base paper making or printing. This has the great advantage of being able to obtain a container sheet having the following properties. For this reason, problems such as blocking in the winding state that occurred due to the application of conventional anti-slip agents, adhesion of sticky substances during the container forming process, falling off of particles to create unevenness, or scratches on the roll surface due to particles. I no longer have to worry about problems like this. In addition, when using a large amount of unfoamed hollow particles, there was a problem of foaming and whitening of the printed surface, but the present invention can foam a small amount of hollow particles to achieve an anti-slip effect, so this problem can be solved. The problem was also resolved.
