Description
Technical field
The present invention relates to give useful antifog property surface treatment agent (antifog treatment agent) of antifog property and antifog property resin sheet, also relate to the manufacture method of antifog property resin sheet and given the container of antifog property to the surface of resin sheet etc.
Background technology
Hydrophobicity synthetic resin sheets such as styrene resin sheet can use aspect the packaging vessel of food etc., and antifog property is lower.Therefore, during the food of packing in the container made from above-mentioned sheet material etc., because the variation of temperature, humidity, water vapour can reduce the transparency with the form of small water droplet attached on the surface of container and produce fog.Reduced visibility thus to content.
Therefore, once proposed to use fatty acid ester etc. to give the method for resin sheet with antifog property.For example, in the public clear 63-62538 communique of spy (patent documentation 1), sucrose fatty ester that coating contains specified proportion, the polymerization degree method at the aqueous solution of the pure and mild polysiloxane emulsion of unmodified polyethylene below 800 is disclosed on the styrene resin film.Open in the flat 10-309785 communique (patent documentation 2) the spy, disclose in the mixture of on one side, be covered sucrose fatty ester and methylcellulose gum the silicone oil that also on this coating, is covered, and the styrene resin sheet of the silicone oil that on another side, is covered.In No. 3241797 specification sheets of patent (patent documentation 3), the method that is coated with the surface treatment agent that contains sucrose fatty ester, polysiloxane emulsion, polyose and/or hydrophilic macromolecule (except polyvinyl alcohol) at least one face of polymeric film is disclosed.Open in the 2003-201355 communique (patent documentation 4) the spy, disclose the antifog property resin sheet on the mixture lining surface of polyvalent alcohol type nonionic surfactants such as using sucrose fatty ester, polyglycerol fatty acid ester and polyethylene glycol type nonionic surfactant.And open in the 2004-238614 communique (patent documentation 5) the spy, the anti-fog disk of using by the non-ethers hydrophilic macromolecule beyond the polyhydric alcohol fatty acid ester, polyvinyl alcohol, having the surface treatment agent lining that unitary ethers hydrophilic macromolecule of oxygen ethylidene and silicone oil constitutes is at least disclosed.
But in these existing antifog property sheets, antifog property is all not too abundant.In other words, above-mentioned antifog property sheet, when in container, packing the pyritous content into, antifog property (the antifog property of high temperature) to the water vapour that content produced is poor, the content (food etc.) that particularly will contain moisture is accommodated in the container, and when preserving at low temperatures, all bad to the antifog property (the antifog property of low temperature) of water vapour or dewfall.And owing to sheet material curled or when being configured as container, antifog property significantly reduces.In other words, be used for the resin sheet (such as the styrene resin sheet) of shaped container, such as with the resin melting mixing, be extruded into sheet, be coated with antifogging agent after the sheet material two-way stretch that will obtain, be rolled into the roller shape after dry.When shaped container, from roller, derive resin sheet then, form the appearance device through thermoforming.But, be accompanied by curling of above-mentioned resin sheet, antifogging agent is by contacting and can shift with the non-antifog treated side of resin sheet, have again, in the process that container is shaped, owing to contacting antifogging agent is shifted, so the antifog property of resin sheet or container or anti-adhesive all significantly reduce with heating member such as hot plate.Particularly be shaped by deep drawn shaping (Shen Twisted り) form when describing device, antifog property can reduce significantly.And antifogging agent can pollute forming mill.And, need to use many silicone oil in order to improve the release property of above-mentioned antifog property sheet.
Open in the 2001-171052 communique (patent documentation 6) the spy and to disclose a kind of styrene resin sheet, at least one face of this styrene resin sheet, with 2～30mg/m
2Glue spread, coating contains the fatty amide of specified proportion and the static inhibitor of polyethylene oxide-poly(propylene oxide) segmented copolymer.In the document, also to have narrated and in static inhibitor, contained silicone oil, the amount of coating of silicone oil is at 1～25mg/m
2Scope in.Open in the 2002-12686 communique (patent documentation 7) the spy, disclose on its at least one face, the resin sheet of the coating composition that is made of fatty amide, polyethylene oxide-poly(propylene oxide) segmented copolymer, silicone oil and water-soluble blue colorant of coating specified proportion, above-mentioned fatty amide and polyethylene oxide-poly(propylene oxide) segmented copolymer constitutes antistatic composition.
But, in these documents, all do not relate to antifog property.Static resistance in above-mentioned sheet material all has improvement to a certain degree, because the ratio of fatty amide is too much, the transparency is reduced.And, all need many silicone oil in order to improve the release property of sheet material.
