Description

Non-electrostatic isolating plate
Technical field
The present invention relates to container is multilayer laminated when making its modularity on tray employed division board (also being called stacking plate).
Background technology
So far, used cans such as belly wash, beer, cooking oil, can, glass container that medical supplies, industrial medicine, liquid seasoning etc. are used or liquid wash the diversified capacity of a large amount of uses of used various fields such as plastic container such as agent, flavoring additives, ice cream.And, the loading and unloading operation mechanization or the automation nearly all of the packing of these containers and transportation etc.
A kind of mode as above-mentioned packing and transportation has the unit loads method.This method is when packing or transfer cask etc., the method that they is accumulated a unit, makes it become one and not load and unload with machine with not breaking in operation process with suitable number or weight.
Promptly, it is to become multiple row multilayer laminated after making its modularity on the tray at the container with some, for the loading and unloading operation of carrying out packings such as shrink wrapping or stretch package, when making container unit, for the stabilization of container, purpose such as prevent to break, prevent dust, insert division board at each layer.
In the past, use the papery goods as division board more.But because of cardboard suction, the moisture absorption etc., mechanical strengths such as its bending stiffness, Dent resistance are low, and repeated use is restricted.And because raw material is a paper, fluffing or damaged, seriously polluted is because of the unhygienic field that is limited to be used in fearness dust such as food and medical supplies.
Though as the division board of having eliminated these problems plastic division board is arranged, the problem that plastic division board exists is that static seriously and easily causes dust.Thereby, as the anti-static method of plastic division board, the method for various interpolation antistatic agents or carbon black has been proposed.
Yet, with the method for adding antistatic agent, because the clean meeting of long-term use or plastic flagstone is oozed out antistatic agent, thus both contaminated environment and cleaning liquid, antistatic properties also reduces.
On the other hand, use the plastic flagstone that adds carbon black, it is free by the surface then to worry carbon dust, and itself becomes dust and becomes environomental pollution source.In addition, make plastic flagstone become corvinus owing to adding carbon black, its use also often is restricted.
Therefore, disclose a kind of division board in the special fair 7-59642 communique of Japan, it obtains antistatic properties by add conducting fibre in polyolefin resin.Like this,, both improved fastness to water and mechanical strength, also obtained to have durability division board good antistatic properties, free from environmental pollution by adding conducting fibre.
But, when in polyolefin resin, adding conducting fibre, because polyolefin-based resins is the insulativity material, will because of conducting fibre within it portion whether form network, promptly, in the degree that whether is in contact with one another between the conducting fibre on the whole plastic flagstone or whether approaches charged electric charge is missed, its antistatic properties produces the drastic change of criticality.Therefore, in case the zone that contacts or keep off between the conducting fibre is arranged, will produce the local low position of antistatic properties, thereby make the antistatic properties instability.
In addition, when using conducting fibre, if not with low speed shaping division board, then in the shaping of division board, conducting fibre is fractureed, perhaps interweave and increase distance between conducting fibre, the capacity rating of division board is reduced because of being difficult to obtain network between the conducting fibre.In other words, have the good anti-static performance, just must reduce forming speed, thereby the manufacturing cost of division board is improved in order on whole plastic flagstone, to make it.
Disclose a kind of division board in the special fair 8-13527 communique of Japan, it is only to add conducting fibre at superficial layer by making the division board multiple stratification, thereby the use amount of conducting fibre is reduced.And a kind of division board is disclosed in Japanese kokai publication hei 11-35064 communique, it is in the division board of abs polymer system, realizes antistatic properties by mixing with hydrophilic polymer.
Yet, make the division board multiple stratification and the method for only adding conducting fibre at superficial layer, make device complicated owing to making multilayer board, the best approach of can not saying so.And with the method for hydrophilic polymer compound, when division board is to make with abs polymer, because abs polymer and hydrophilic polymer have intermiscibility and can realize antistatic properties, but division board is when making with polyolefin resin, polyolefin-based resins is a hydrophobic polymer, with the intermiscibility extreme difference of hydrophilic polymer.Therefore, even polyolefin resin and hydrophilic polymer mix, form the isolated island structure owing to both are separated from each other when being shaped, it is difficult obtaining antistatic properties on the whole surface of division board.
Summary of the invention
First purpose of the present invention provides a kind of non-electrostatic isolating plate, and it is inexpensive and can make easily, and can obtain antistatic properties on whole plate face.
Second purpose of the present invention provides a kind of non-electrostatic isolating plate, and it is to add conducting fibre and obtain in the antistatic properties in polyolefin-based resins, even when at high speed is shaped, also can obtain stable antistatic properties on whole plate face.
Adopt first scheme of the present invention, a kind of division board is provided, it is in containing the non-electrostatic isolating plate of polyolefin-based resins, it is characterized in that: containing the copolymer resins that will have polyolefin skeleton and hydrophilic polymer skeleton at least, to be blended in said polyolefins be composite in the resin, and its surperficial intrinsic impedance value is 10 11Below the Ω.
Like this, be blended in the polyolefin-based resins, this copolymer resins and polyolefin-based resins are mixed and be scattered in wherein by the copolymer resins that will have polyolefin skeleton and hydrophilic polymer skeleton.Therefore, even use the division board of polyolefin-based resins, also can on whole plate face, obtain antistatic properties under the situation of no conducting fibre.And owing to only by mix copolymer resins in polyolefin-based resins, just can make and the common identical product of polyolefin-based resins plate that is shaped, making also is very easily.
Adopt alternative plan of the present invention, a kind of division board is provided, it is in containing the no electrostatic isolation of polyolefin-based resins, it is characterized in that: contain at least that to be blended in said polyolefins be composite in the resin with having the copolymer resins of polyolefin skeleton and hydrophilic polymer skeleton and conducting fibre material, its surperficial intrinsic impedance value is 10 7Below the Ω.
Like this, only be blended in the polyolefin-based resins, this copolymer resins and polyolefin resin are mixed and be scattered in wherein by the copolymer resins that will have polyolefin skeleton and hydrophilic polymer skeleton.Its result, even at high speed shaping division board and when distance between conducting fibre is increased, because the effect of copolymer resins, the network of conducting fibre still can form well, thereby can obtain stable antistatic properties on whole plate face.
The specific embodiment
Below, first embodiment is described
The division board of present embodiment be with polyolefin-based resins as first composition, the copolymer resins that will have polyolefin backbone and hydrophilic polymer skeleton is as second composition, after their are mixed, is configured as tabular by extrusion molding etc.
Like this, join first composition, be in the matrix of polyolefin-based resins by the copolymer resins that will have polyolefin skeleton and hydrophilic polymer skeleton, because the polyolefin skeleton of copolymer resins part has intermiscibility with polyolefin-based resins, even use the division board as the polyolefin-based resins of hydrophobic resin, copolymer resins is also can be partly fused and be scattered in wherein with the matrix of polyolefin-based resins.Its result even use the higher conducting fibre of price, also can make the whole isolated plate obtain antistatic properties.In addition, thereby contain copolymer resins in the polyolefin-based resins and have antistatic properties, can permanently keep its antistatic properties, and be unlikely to as the division board that adds antistatic agent in the past, antistatic properties to be reduced because of cleaning by making.And, owing to needn't use carbon black, can prevent that the dust that produces because of carbon black itself from also can prevent the blackout of tone.Have again, because without conducting fibre, thereby can conveniently make division board efficiently with the process identical with making common polyolefin-based resins plate.
The preferred 3-20 quality of the content of copolymer resins % in the division board.During less than 3 quality %, the danger that can not obtain sufficient antistatic properties is arranged.And when surpassing 20 quality %, possibility of the character that changes the polyolefin resin matrix greatly arranged, and, owing to the price height of copolymer resins, also unfavorable to manufacturing cost than polyolefin-based resins.
As the polyolefin-based resins of first composition, can use acrylic resin, poly-vinyl resin, ethylene, propylene copolymer resins etc.As the polyolefin skeleton that constitutes copolymer resins,, preferably use and the polyolefin-based resins identical materials for copolymer resins is evenly dispersed in the polyolefin-based resins.For example, when polyolefin-based resins is polypropylene, should make the polyolefin skeleton with polypropylene.In addition, the hydrophilic polymer skeleton as constituting copolymer resins can utilize the poly-mer with amide group, alcohol radical, carboxyl etc., the concrete polyamide backbone enumerated, polyvinyl alcohol skeleton, polyethylene glycol backbone etc.
The surperficial intrinsic impedance value of division board is 10 11Below the Ω.Surface intrinsic impedance value surpasses 10 11During Ω, antistatic properties reduces, and adsorbs dust easily.
The thickness of division board is advisable with the 0.3-15mm scope.Thickness is less than 0.3mm, mechanical strength deficiencies such as the rigidity of division board, and when surpassing 15mm, the weight of division board increases, and might bring obstacle to the automation and the operation of loading and unloading operation.When division board be used for beverage/food require with container etc. with container or medicine sanitary condition container transportation and when packing, produce mould and assorted bacterium on the division board in order to be suppressed at, preferably apply antiseptic on the surface of division board at least.As antiseptic, be not particularly limited, can use antibiotic property metals such as argentiferous, copper, zinc, especially contain the dissolubility glass of silver ion.In addition, as the method that in division board, applies antiseptic, can adopt the back that is shaped in the method for the surface coating antiseptic of division board and the division board material before shaping, to add as in the method for ternary antiseptic any.Owing to add the coating operation after the method for antiseptic does not need to be shaped in the division board material before shaping, but simplified manufacturing technique, reduce manufacturing cost.
In above-mentioned example, though with the individual layer division board is that example describes, but also can be used for multiple-structure, at this moment, the plate that will be made of polyolefin-based resins is as main stor(e)y, on main stor(e)y single face or two sides, constitute multilayer as skin lay-up by the plate that will contain above-mentioned at least the first composition and second composition, can reduce the consumption of copolymer resins.
Below, second embodiment is described.
In the above-described first embodiment, do not use conducting fibre,, require more performance-oriented division board sometimes yet though on whole plate face, realized stable antistatic properties.Present embodiment uses conducting fibre satisfying the requirement of this respect, and by using conducting fibre so that suppress the reduction of capacity rating as far as possible.
Promptly, the division board of present embodiment is as first composition with polyolefin-based resins, the copolymer resins that will have polyolefin skeleton and hydrophilic polymer skeleton is as second composition, and conducting fibre as the 3rd composition, is mixed the back with their and is configured as tabular by extruding formation method etc.
About first composition and second composition, constitute they resin and content to equal first embodiment identical.
As ternary conducting fibre, be used to give the division board antistatic properties.By making it contain conducting fibre, unlikelyly because of cleaning anti-static effect is reduced as adding antistatic agent, when can forever keep antistatic properties,, can prevent dust because of carbon black generation itself owing to not using carbon black.
As conducting fibre, except that general carbon fiber, can enumerate the metal fibre of forming by aluminium, brass, corrosion-resistant steel etc., the fiber of metal powders such as coated with silver, copper, brass, nickel on glass fibre, or sneak into syntheticfibres of metal powders such as silver, copper, brass, nickel etc.Wherein, the carbon fiber of carbon fiber and nickel coating from rigidity and aspect of performance such as the surface impedance value when adding so from wait in price be thought of as best.Carbon fiber has PAN series and pitch series, and PAN series can improve rigidity.In addition, fiber can be any in chopped fiber or the long fibre, but preferably can obtain the long fibre of remarkable result with few addition.
On the other hand, as the copolymer resins of second composition, even at high speed shaping division board, also can get rid of the harmful effect that therefore conducting fibre is produced, the characteristic of conducting fibre is brought into play to greatest extent, and its result is used in and makes antistatic properties stable on the whole plate face.
When in polyolefin-based resins, adding conducting fibre when giving its antistatic properties, as mentioned above, to have stable antistatic properties in order making on the whole plate face, must to make the network that on whole plate face, forms conducting fibre between the conducting fibre mutually with contact or approaching state.But, when adding conducting fibre, as at high speed shaping division board, during shaping because the shearing force that is applied on the polyolefin-based resins of fusion fractures conducting fibre, its result, the mean length of conducting fibre shortens, its network suffers damage.Particularly remarkable when extrusion molding, forming speed one height under the situation of adding conducting fibre, the degree of alignment of conducting fibre on the direction of extrusion increases, and its crisscross going up just is difficult to obtain at interweaving between the conducting fibre.
On the other hand, as other method of giving the resin antistatic properties, known have a mixing hydrophilic polymer, the airborne moisture that adsorbs from the teeth outwards by this hydrophilic polymer, the electric charge that produces on resin is missed by resin, thereby prevented the resin static electrification.If utilize this point,, still can think to have formed the conducting fibre network by hydrophilic polymer even conducting fibre fractures or in direction of extrusion degree of alignment increase etc. the distance between conducting fibre is increased.
But, because polyolefin-based resins is hydrophobic, there is not intermiscibility with the additive of possess hydrophilic property, only in polyolefin-based resins, mix hydrophilic polymer, both are separated from each other when being shaped and form the isolated island structure.Its result, hydrophilic polymers can not be dispersed in the polyolefin-based resins, can not realize utilizing conducting fibre just to make antistatic properties stable on whole plate face.
Therefore, as mentioned above, join in the matrix as the polyolefin-based resins of first composition by the copolymer resins that will have polyolefin skeleton and wetting ability skeleton, because the polyolefin skeleton of copolymer resins part has intermiscibility with polyolefin-based resins, copolymer resins just partly dissolves in the matrix of polyolefin-based resins and is scattered in wherein.Therefore, distance between the conducting fibre that electric charge can move is compared increase with the situation of having only polyolefin-based resins, thereby, even when distance between conducting fibre being increased by the high-rate forming division board, because the effect of copolymer resins, can make becomes the state that electric charge can move between conducting fibre, thereby can obtain stable antistatic properties on whole plate face.
The surperficial intrinsic impedance value of division board requires the value for being difficult to adsorb dust, in the present embodiment, considers and contains conducting fibre, is necessary to fix on 10 7Below the Ω.When surperficial intrinsic impedance value surpasses 10 7During Ω, antistatic properties just reduces, and adsorbs dust easily.The thickness of division board is identical with first embodiment.Even in the present embodiment, identical with described in first embodiment according to the purposes of division board, preferably applies antiseptic on its surface at least.Have, in the present embodiment, identical with described in first embodiment also can be made multiple-structure with division board again.
