Description
Technical field
The present invention relates to for rust-proof component and the wrapping material that will need antirust various metal products bale packing keepings.
Background technology
All the time, the transportation of the antirust bale packing of metal products is adopted is to immerse slushing oil with the method that intercepts atmosphere and transport or by wrapping in anti-tarnish paper＜the scribble paper of rust-preventive agent〉in the treatment process method of transporting.But, before 30～40 years, in order to be the metal products of representative to overseas outlet take automobile component, wish cheapness, operability good, do not take the wrapping material of twists and turns when using.Its result, some enterprises, personal development have the Plastic Packaging Materials of antirust function when having gone out transportation.
But, customer requirements not only will have antirust function when transportation now, and as the responsibility of metal products producer, goods also to be arranged in the guarantee of stores keeping, even thereby require wrapping material producer also can keep antirust function in providing during stores keeping, do not make goods produce the deteriorated wrapping material of function.
Particularly goods in the situation that the stores keeping time be 10 years long-term like this, although need to through also non-corrosive of metal products surface in very long period, between maintaining period, certainly arrive non-corrosive very difficult.
Dichan is divided into 2 kinds of quick-acting rust-preventive agent and slow rust-preventive agent according to the distinctive vapo(u)rability of material.When only adding quick-acting rust-preventive agent, though can discharge in a short time a large amount of antirust compositions, be not suitable for antirust for a long time.In addition, when only using slow rust-preventive agent, the rust-proof effect at initial stage is insufficient.
Therefore, make up quick-acting rust-preventive agent and slow rust-preventive agent, be used as embodying the method for stable rust-proof effect.
On the other hand, as the method for the long-term effect that obtains dichan, the method for disperseing, supporting is arranged in resin.As resin, on easy to process, the nonpolarity polyolefin resin of more options take Low Density Polyethylene as representative, but because common above-mentioned resin is difficult to mix with rust-preventive agent, so the gasification mode of rust-preventive agent still can be not steady in a long-term.
If add a large amount of rust-preventive agent for replenishing this deficiency, after goods are made, within shorter period, product surface can be separated out rust-preventive agent, occurs namely that what is called is oozed out or frosting phenomenon, not only make exterior of commodity significantly impaired, diminish to a great extent commodity value, also can be because this precipitate be attached directly on the metal products, the complaint problem that might develop into that foreign matter is sneaked into etc., so, can not say and avoid fully this not enough method.
And, when only in nonpolarity polyolefine, cooperating rust-preventive agent merely, sometimes also can get rusty during the several years in keeping, the result still is difficult to make goods also to continue the maintenance rust-proof effect in the stores keeping time through the above-mentioned several years.
The example of the molding that has shown some in resin, to cooperate rust-preventive agent in the following patent documentation 1～3 and formed, comprise the hot-melt-bondable polyolefine but only put down in writing in the patent documentation 1, dichan, the composition of oxidizability metal-powder and zeolite, only put down in writing the composition that contains the dichans such as alkyl dicarboxylic aid's ammonium salt in the thermoplastic resins such as LDPE in the patent documentation 2, only put down in writing the weighting agent that in polyolefine etc., cooperates calcium carbonate etc. in the patent documentation 3, as the rust-preventive agent of the mineral acid of organic amine or organic acid salt and the antirust molding of using that forms, thereby but all not to add the porousness weighting agent with specific specific surface area to bring into play for a long time the invention that rust-preventing characteristic is purpose.

Embodiment
The present inventor has found to be used for the long-term rust-proof component that continues rust-proof effect first by adding, making up the specific porous adsorbent as the 3rd composition in containing the rust-preventing characteristic resin combination of specific resin and specific rust-preventive agent.
As the binder resin that uses among the present invention, according to knowledge up to the present, can exemplify in processibility, security and environment aspect be useful polyolefin resin all, polyethylene for example, the α of polypropylene etc.-polyolefinic homopolymer, ethylene-propylene copolymer, ethene-1-Butylene copolymer, ethene-4 methyl 1 pentene copolymer, the ethene of ethene-hexene copolymer etc. and the α of C3-C8-polyolefinic multipolymer, vinyl-vinyl acetate copolymer, ethylene-acrylic acid copolymer, the organic carboxyl acid derivative with ethene unsaturated link(age) of ethane-acetic acid ethyenyl ester-methylmethacrylate copolymer etc. and the multipolymer of ethene etc.
In the said polyolefins resinoid, when for example using as the purposes of wrapping material, from the simplicity of goods cost, manufacturing, be fit to select polyethylene, can consider that the various poly characteristic from the Low Density Polyethylene to the high density polyethylene(HDPE) adopts.
But from conclusion up to now, preferred density is 0.880～0.950g/cm
3, 0.910～0.930g/cm more preferably
3Polyethylene.
In addition, the manufacturing process of this resin is not particularly limited, and can adopt known resin molding method.
Among the present invention, as dichan, for being selected from mineral acid or organic acid amine/ammonium/metal-salt, the Urea Series compound, one kind or two or more dichan in the hetero ring type compound, specifically, can exemplify and be selected from the list-thanomin that in environment for use, shows gasification property, two-thanomin, three-thanomin, just-butylamine, two-butylamine, uncle-butylamine, hexamethylene-diamine, vulkacit H, list-hexahydroaniline, two-hexahydroaniline, Isopropylamine, oleyl amine, naphthylamines, the phosphoric acid of two-aniline, nitrous acid, carbonic acid, the organic amine salt of carboxylate salt, be selected from the phthalic acid ammonium, ammonium benzoate, ammonium stearate, dodecanoic acid ammonium, decanoic acid ammonium, ammonium sebacate, the ammonium carboxylate salt of ammonium adipate, be selected from urea, methyl urea, ethyl urea, propyl group urea, thio urea, the Urea Series compound of urotropine is selected from benzotriazole, Methylbenzotriazole, carboxyl benzotriazole, the 5-hydroxybenzotriazole, 3-methyl-5-hydroxypyrazoles, 5-amino-1H tetrazole, imidazoles, glyoxal ethyline, the 5-Methylimidazole, benzoglyoxaline, the hetero ring type compound of mercaptobenzothiazole etc. etc.
And as required, basic metal, the alkali earth metal salt of the mineral acids such as the nitrous acid by adding the gasification of tool not property, carbonic acid, phosphoric acid, boric acid, silicic acid also can reach the purpose of further improving rust-proof effect.
For addition, rust-proof effect according to object metal and requirement, further the vapour pressure characteristic according to above-mentioned dichan is different, its amount that is fit to is also different, but common when very few, antirust composition can not disperse on a large scale, can't obtain sufficient rust-proof effect, on the contrary, can cause in the time of too much and ooze out, so, in order to obtain stable effect, with respect to having the 100 weight part polyolefin resins that melting index (MFR) is 0.1～30.0g/10min., add 0.1～10 weight part effective, and then the viewpoint from making, more preferably 0.5～5 weight part.
But, the higher limit of this addition is applicable in the present invention who uses following porous adsorbent, when not adding this porous adsorbent, when adding dichan without the degree of oozing out, the addible maximum addition that oozes out that do not cause is lower amount far away.
Secondly, center function of the present invention is the persistence of rust-proof effect.Therefore, the gasification burst size of dichan can be passed through the addition control as the porous adsorbent of the 3rd composition.In addition, by the porous adsorbent is dispersed in the resin, also can be to alleviating oozing out and reduce the rust-preventive agent smell and playing a role of dichan.

2More than/the g, 300m more preferably
2More than/the g.And consider the dispersiveness that is distributed in the binder resin on a large scale, more preferably 800m
2Below/the g.
The addition of porous adsorbent must change with the variation of dichan addition, when addition is few, sometimes rust-preventive agent can ooze out from binder resin, when addition is many, the superficiality of goods is worsened, also can keep doughtily dichan because crossing, suppress sometimes the performance of rust-proof effect, so, for obtaining stable rustless property, with respect to 1 weight part rust-preventive agent, need 0.2～30 weight part porous adsorbent, 1.0～15 weight parts more preferably are in this scope, for the metallic element as object is brought into play rust-proof effect for a long time, need to select composition and the addition of dichan.
