Abstract
The maleic anhydride that the invention discloses a kind of for bonding EVOH is grafted PE, it includes the component of following mass fraction: PE60~80 part, EVA10~15 part, EBA10~15 part, 1~3 part of maleic anhydride, 0.5~2 part of initiator and 1~2 part of phosphite ester.Compared with prior art, the present invention passes through PE, EVA, EBA, maleic anhydride, initiator, phosphite ester interaction, the maleic anhydride grafting PE and EVOH material prepared has good adhesive fastness, and the smell of product is low, the penetrating odor without general MAH grafted products.
Description
Technical field
The invention belongs to modifying plastics fields, and in particular to a kind of maleic anhydride grafting PE for bonding EVOH.
Background technique
EVOH is always to use most high barrier materials, and the film type of this material is other than non-stretching type, also
There are biaxial tension type, aluminium-vapour deposition type, adhesive application type etc., the barrier property of EVOH depends on content, in general
When ethylene contents increase, the barrier property of gas is reduced, but easy to process.EVOH outstanding feature is that have pole to gas
Good barrier property and fabulous processing performance, otherwise see-through degree, glossiness, mechanical strength, retractility, wearability, cold resistance and
Surface strength is all very excellent.Wherein adhesive application type is with very extensive one kind, adhesive main component therein
It is exactly maleic anhydride grafting PE, but the maleic anhydride grafting general grafting rate of PE currently on the market is difficult to do height, generally on 1% left side
The right side, which results in the bond effects of binder can only meet some low-end markets.The high-end high bond effect of needs is difficult
Reach.The present invention relates to maleic anhydride grafting PE by selecting suitable basis material and initiator, squeezed by twin-screw
The grafting rate of maleic anhydride grafting PE out can accomplish 3 or so.It is able to satisfy the market demand of most of senior middle school's low sides, and
Product odour is lower, and the crystal point that extrusion process generates is less, does not influence the performance of extrusion film.
Summary of the invention
The maleic anhydride that the technical problem to be solved in the present invention is to provide a kind of for bonding EVOH is grafted PE, existing to solve
There is the problems such as ineffective existing for technology.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of maleic anhydride grafting PE for bonding EVOH, it includes the component of following mass fraction:
Wherein, the component of preferably following mass fraction:
Wherein, the PE is low density linear polyethylene of the MI in 4~5g/10min, squeezes out rank, and resistance to cross-linking effect is excellent
It is different.
Wherein, the EVA is VA content 32%, ethylene-vinyl acetate copolymer of the MI 100 or more, high fluidity
It reduces material and rests on the time in extrusion process, avoid generating excessive crosslinking.
Wherein, the EBA is ethylene butyl acrylate of the MI 30 or more, on the one hand production can be improved in the addition of EBA
On the other hand the grafting rate of product can also reduce the crosslinking rate of product, reduce the generation of crystal point.
Wherein, the maleic anhydride is that the MAH of the MAH high mesh number of 200 mesh of mesh number or more can be in extrusion process
In can disperse well with other materials, avoid conventional MAH sheet or agglomeration lead to the uneven of material.
Wherein, the initiator is that 2,5- dimethyl -2,5- bis- (t-butyl peroxies) alkynes, the initiator do not have benzene
Ring, extrusion reaction will not generate niff in the process and have suitable reactivity.
Wherein, the phosphite ester is colourless or pale yellow viscous liquid of the molecular weight 950, steady with outstanding heat
Qualitative energy, can prevent the crosslinking of material under extrusion temperature.
The preparation method of the above-mentioned maleic anhydride grafting PE for bonding EVOH includes the following steps:
By high-speed mixer is added after each component raw material accurate weighing of formula ratio, (additional amount must be controlled in mixed at high speed
Between the 0.5~0.75 of machine volume), mixing puts into double screw extruder and -- squeezes out tie rod -- pelletizing -- drying -- after 6~8 minutes
Packaging, the extrusion temperature of double screw extruder are 120~170 degree, vacuum degree < ﹣ 0.06MPa.
The utility model has the advantages that compared with prior art, the present invention has the advantage that
PE in through the invention, EVA, EBA, maleic anhydride, initiator, phosphite ester interaction are prepared
The maleic anhydride grafting PE and EVOH material come has good adhesive fastness, and the smell of product is low, and no general MAH grafting produces
The penetrating odor of product.
