Abstract
The utility model belongs to the technical field of papermaking and particularly relates to isolation paper and release paper mainly used in the industrial fields such as food sanitation, medicine package, electronic appliances, articles for daily use, cosmetics, physical distribution in supermarkets, express mail service and the like. The isolation paper provided by the utility model is composed of a raw paper layer as well as a precoated layer and an insulated layer which are sequentially coated on the surface of the raw paper layer; and the release paper is formed by coating solvent-free silicon oil on the surface of the isolation paper and sequentially comprises the raw paper layer, the precoated layer, the isolated layer and a silicon oil layer from bottom to top. The raw paper layer is of low-weight tissue paper (such as release raw paper and the like) of 30-60g/m<2> or cultural paper (such as two-sized offset paper and the like) of 50-200g/m<2>. The isolation paper and the release paper have the characteristics of low raw paper performance requirement, good isolation and release performances, high paper smoothness, no pollution, easiness for recycling, stable performance and the like; and a production process of the isolation paper and the release paper has the advantages of low manufacturing cost, high production efficiency, benefit for large-scale production and the like.
Description
Technical field
The utility model belongs to pulp technology for making paper, particularly a kind of barrier paper and release liners that is mainly used in the industry fields such as food hygiene, medical packaging, electronic apparatus, commodity, cosmetics, supermarket logistics, express mail service.
Background technology
Traditional barrier paper is comprised of body paper, separation layer.Its preparation technology is the surperficial film one deck isolating agent (being commonly called as film) at body paper, the isolating agent that adopts generally is polyethylene (PE), no matter be film or CN201010166004.9 " processing technology of leaching membrane paper and release liners " mention produce barrier paper with coating method, all to use polyolefin (PE or PP), after being coated on the paper, this class polyolefin cause paper to process very difficult with traditional way of recycling, because the polyolefin products biodegradability is low, also may work the mischief to environment in addition.
Release liners claims again silicone oil paper, and separate paper mainly plays the effect of the sticking object in isolation strip, such as adhesive tape.Generally need to be stripped from use, abandon.Release liners generally is divided into moulds release liners and without moulding release liners.Mould release liners, that is: the surface-coated one deck mould release (being mainly silicone oil) at leaching membrane paper forms, owing to adopt polyolefin products, causes paper to process very difficult with traditional way of recycling, because the polyolefin products biodegradability is low, also may work the mischief to environment in addition.Without moulding release liners, mainly contain Ge Laxin, CCK etc. through other release liners of special treatment, such release liners has smoothness height, grease resistance can be good, consume the advantages such as mould release is few during coating, but price, the source of goods is in short supply, is difficult to satisfy the needs of production and economic benefit.The low grammes per square metre release liners of express mail service special use, also belong to without moulding the release liners category, this class release liners quality requirement height and huge market demand, the product that yet existing market is improved quality, production efficiency is high is also few, although CN200910073834.4 " release liners and the preparation method that are used for back glue bag for postal service express delivery " mentions a kind of novel preparation method, but it must the selecting technology index request high, the measured coated paper of matter, and the Shortcomings part still such as mould release consumption, release effect, production efficiency.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to remedy above-mentioned prior art, a kind of novel barrier paper and the processing technology of release liners are provided, it has, and the body paper performance requirement is low, isolation (release) effective, characteristics such as paper formation high, pollution-free, easy recovery, stable performance, and its production technology has low cost of manufacture, production efficiency height, be beneficial to the advantage such as large-scale production.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of barrier paper comprises original paper layer, and described original paper layer surface applies precoated shet and separation layer successively.
A kind of release liners comprises original paper layer, and described original paper layer surface applies successively precoated shet, separation layer and silicon layer and forms.
Described original paper layer is 30～60g/m
2Low grammes per square metre tissue paper (such as neutral sizing etc.) or 50～200g/m
2Cultural paper (such as wood-free paper etc.).
The beneficial effects of the utility model are: 1. 30～60g/m of choosing of the method
2Low grammes per square metre tissue paper (such as neutral sizing etc.) or 50～200g/m
2Cultural paper (such as wood-free paper etc.), need not through special treatment, technical requirement is not high, wide material sources, supply is sufficient, and is cheap.2. the barrier paper of the method preparation, planarization is good, isolation effect is good.3. the release liners of the method preparation, release effective, ageing-resistant performance good, silicone oil consumption is few, be coated with the silicon amount and be low to moderate 0.6g/m
2, still can reach good release effect, further reduced production cost.4. barrier paper and the release liners of the method preparation are not used polyolefine material and solvent-borne type mould release, and be pollution-free, easily reclaims, and environment is not worked the mischief.5. the release liners of this method preparation is applied widely, can replace the film release liners to be used for the label field, can replace 30～60g/m again
2Low grammes per square metre release liners is used for defending the multiple fields such as material, express mail service.
Description of drawings
Fig. 1 is the utility model barrier paper structural representation;
