Description
Technical field
The present invention relates to hot melt adhesive films, and in particular to the preparation method of high quality heat melten gel breathable films.
Background technology
The olefines hot melt adhesive film largely used on the market at present has following several different types of hot melt adhesive raw materials：
Different vinyl acetates（VA）The ethylene-vinyl acetate copolymer of content（EVA）；
Different acrylic acid（AA）The ethylene acrylic acid co polymer of content（EAA）；
Polyethylene（PE）Grafted maleic anhydride（MAH）Copolymer（PE-graft-MAH）；
The hot melt collagen-based materials of three of the above system are all to have advantage using field specific, lack popularity with leading to
With type, hot melt adhesive film promote on a large scale in use there are it is respective the shortcomings that！
EVA systems：Although high VA contents ensure that sufficient caking property, the hot melt adhesive material fusing point of this structure is very
Low, the limitation that terminal client uses is very big, particularly outdoor subscriber, can not meet the application conditions that summer is exposed to the sun！In addition,
EVA system glued membrane poor water resistances can not meet the use condition of the industries such as clothes, open air！Although someone has developed on the market
The EVA hot-melt adhesive film of cross-linking type, the shortcomings that substantially improving aforementioned list, but the product are due to price height, product preservation condition
It is harsh（It seals, avoid moisture）, the period is long, reduces enterprises production efficiency using shaping by client, these problems cause to be crosslinked
Type EVA adhesive film is promoted without the daily civilian industry of normal direction.
EAA systems：The material is since special polymerization, at present EAA are mainly produced by DOW of America, Du Pont, the production
Product are in monopoly position in the world.Also, serious aging, the considerable of the country of inflow at present are the equipment of the Dow Chemical Company
Secondary board material, performance are unstable.Although price is not very high, to being the client of film in the stability of performance and the appearance of film
Quality etc. will bring strong influence.Equally, it is also the deficiency of EAA systems the defects of EVA systems, heat resistance is glued with height
Knot property still can not accomplish to balance, and the EAA heat resisting temperatures of high AA contents are no more than 60 degree.
PE-graft-MAH systems：PE materials are broadly divided into LDPE, LLDPE, HDPE three categories, and fusing point is substantially all 95
Between DEG C -135 DEG C, for most of civilian clients, there is no problem for heat resistance.But the polarity or adhesive strength of the system
Mainly by maleic anhydride（MAH）It provides, and the system is since strand is saturation chain structure, particularly HDPE material, point
Subchain branch is all fewer, it is not easy to form active site, grafting rate is often very low, is usually no more than 1%.Film user is more caused
Life is that this stability of material is poor, and containing more gel particles, film appearance is very poor or even can not form a film.In addition, HDPE bodies
When the grafted material of system does film, transparency is very low.
Processing method：Since existing hot melt adhesive EVA, EAA glued membrane is mainly using the technique of blade coating, it is necessary to using release paper
Deng as supporting, for film article, cost that the cost of lining paper will account for 10%-40% not only increases the cost of client, also makes
Into great waste, it is unfavorable for environmental protection, and product is breathed freely, penetrability is poor.Material prepared by the present invention can be directly using stream
Prolong method production, the basement membrane being cast out can puncture by engraved roll, using biaxial tension, expand air hole, reach it is ventilative,
The effect of moisture-inhibiting.
