Description
Technical field
The present invention relates to a kind of multi-layer co-extruded hose adhering resin and preparation method thereof, more particularly to a kind of resistance to environment should
Power high strength multi-layer co-extrusion hose adhering resin, belongs to adhering resin field.
Background technology
As China's expanding economy and consumption mode constantly change, packaging industry needs various types of high functions, specially
With the packing film of change, such as the fresh-keeping function for improving food occurred in the market, the high-barrier of extension article shelf-life
Property packaging film, cosmetics composite soft tube, electronic device transportation and packing etc..The film article of these high functionalities is multi-layer co-extruded
The result of thin film technique development.Multi-layer co-extruded film is mainly characterized by economy, and functional, intensity is high.Such as PVDC is to oxygen
Gas and vapor have very high barrier property, but its price is high, and process can generate harmful chlorine, therefore use
The film of the materials coextrusion blow such as PA and LDPE, LLDPE, HDPE, not only meets barrier property, but also meets the necessary machinery of packaging
Intensity, cost performance is reasonable, has the higher market competitiveness.So multi-layer co-extruded composite soft tube is exactly to absorb layers of material
Advantage meets cost-effective, the feature of environmental protection dispatched from the factory from production and processing to finished product to meet requirement of the product to each performance indicator
It is good to wait requirement.
The so-called multi-layer co-extruded plural layers for being exactly extruded into sharp interface layer simultaneously by a die head, and wherein
Bonding between layers of material is just particularly important, and comparative maturity is with ethene-vinyl acetate, ethylene, propylene on the market
The copolymers such as acid, ethylene methacrylic acid are as adhesive layer, but this adhesive lacks heat resistance, while cost is also higher.
And the research of modified PE or MODIFIED PP hot melt adhesive at home is also fewer, it is few applied to just more seeming for composite soft tube packaging
See, the functional molecular distribution uniformity difficulty that mainly modified PE is grafted when either PP hot melt adhesive is coextruded in PE or PP,
How being evenly distributed of graft is ensured, peeling force is big and stablizes persistently, and environmental stress resistance is strong etc., it is necessary to it does further
Research and discussion.
The content of the invention
The present invention in view of the deficienciess of the prior art, the present invention provides one kind there is environmental stress resistance high strength multi-layer to be total to
Hose special bonding resin and preparation method thereof is squeezed, the adhering resin is big, viscous with UV resistant, weatherability, peel strength
It connects and stablizes performance lasting, that the range of work is wide.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of multi-layer co-extruded hose adhering resin, it is described
Adhering resin includes following raw material components and mass parts：
The present invention is further arranged to, and the adhering resin further includes 0.2~1 mass parts vinyl bis-stearamides.
The present invention is further arranged to, and the adhering resin further includes 0.1~0.5 mass parts benzotriazole uvioresistant
Agent.
The present invention is further arranged to, and the adhering resin further includes 10~20 mass parts modified sodium silicate powder.
The present invention is further arranged to, and the adhering resin further includes 0.5~2 mass parts talcum powder.
The present invention is further arranged to, and the adhering resin further includes 1~4 mass parts calcium-zinc composite stabilizing agent.
The present invention is further arranged to, and the adhering resin further includes 0.3~0.6 mass parts resistance phenolic antioxidant.
The present invention is further arranged to, and the resistance phenolic antioxidant is the one or more in 1010,1076 or B215.
The present invention also provides the preparation method of multi-layer co-extruded hose adhering resin, step is as follows：(1) prepared by masterbatch：
By LLDPE, Glycidyl methacrylate acid lipid, initiator di-tert-butyl peroxide prior to being uniformly mixed in high-speed mixer,
Then fusion-grafting is carried out in double screw extruder, rotating speed 1000rpm, 4th area of processing temperature point are respectively 190 DEG C, and 200
DEG C, 210 DEG C, 220 DEG C, extrusion, water cooling, air-dried, pelletizing to obtain the final product；(2) prepared by adhering resin：Remaining component is uniformly mixed,
180~210 DEG C are granulated by the way that double screw extruder is extruded and are dried to obtain the adhering resin.
The multi-layer co-extruded composite soft tube of the present invention is modified with adhering resin by LLDPE linear low density polyethylene,
Chemical graft polar micromolecules group on nonpolar polyethylene analysis chain, realizes the high-barriers such as vistanex and PA/EVOH
Property resin bonding, had both remained the mechanical property of vistanex, low temperature resistant, ageing-resistant, resistant to chemical etching, and can realize PA/
The high barrier of EVOH ensure that the practicability and security of composite soft tube.
Graft modification linear low density polyethylene used in the present invention is compared with conventional ethylene-ethyl acrylate copolymer system application
It is less, but compared with ethylene-ethyl acrylate copolymer, environmental stress resistance is good, at low cost, easy to process, and it is fine with nitric acid
Dimension is known as preferable compatibility, and the toughness of composite soft tube can be remarkably reinforced.
Dispersant vinyl bis-stearamides used in the present invention are mainly used for the wettability of regulation system, while can change
Dispersiveness between kind formulatory agents makes the homogeneity that adhering resin is bonded more preferably more stable.
The adhering resin of the present invention also has excellent processing performance, is applicable to Multi-layer co-extrusion film-blowing (above blow/under blow)
Technique.
The safe and healthy non-poisonous material of the present invention generates.
