Abstract
The present invention relates to a kind of PE Foam, refer more particularly to the production technique of the low PE Foam of a kind of good pressure-resistant performance and production cost.It comprises that agitating procedure, feeding drive operation, heat fused operation, foamed process and extrude operation, agitating procedure: new LDPE particle and circulation recovery LDPE material are mixed; Feeding drives operation: solid-state LDPE particle enters through opening for feed, is done to drive being fed forward by spiral shell; The heat fused operation: the electrically heated ring slowly is melted into liquid state with LDPE; Foamed process: the polyethylene of high-temperature liquid state is foamed into cavernous structure under the katalysis of attached material monoresin and coal gas; Extrude operation: the PE Foam after the foaming is extruded from die head after cooling off.The invention has the beneficial effects as follows: improved the PE Foam surface tissue, existing cavernous structure is changed over membrane structure, and then increased the withstand voltage properties and the shock-absorbing capacity of PE Foam.Because improved the shock-absorbing capacity of PE Foam material, so the product that has guaranteed client safety coefficient in transit.
Description
Technical field
The present invention relates to a kind of PE Foam, refer more particularly to the production technique of the low PE Foam of a kind of good pressure-resistant performance and production cost.
Background technology
The polyethylene foam cotton is the non-crosslinked unicellular structure, claims PE Foam (EPE) again, is a kind of wrapping material of novel environment friendly.It produces countless separated foams by new LDPE (film grade) fat through physical blowing and constitutes.Overcome that common foamed glue is frangible, the shortcoming of distortion, recovery difference.Plurality of advantages such as have water proof protection against the tide, shockproof, sound insulation, insulation, plastic performance is good, toughness strong, reconstituted circularly, environmental protection, crashworthiness power are strong also has good chemical resistance.It is the ideal substitute of Traditional Packing material.The packing that is widely used in the multiple product such as internal packing, daily necessities of electronic apparatus, instrument, computer, sound equipment, medicine equipment, industry control cabinet, lamp decoration, artwork, glass, pottery, household electrical appliances, spraying, furniture, drinks and Gift Package, hardware, toy, melon and fruit, leather shoes.After adding antistatic agent and fire retardant, more apparent its remarkable performance.
PE Foam also is used for the cushions of handbag case and bag in a large number in addition, the floatation device of industrial sound insulation, lagging material, agricultural lagging material, aquaculture, the anti-protection pad of sports goods, the operation at sea buoyant apparatus, the floor finiss in family, hotel, liner or the like.Its tubing is used for industries such as air-conditioning, perambulator, toy for children, family property in a large number.
The existing PE Foam product surface of producing with general production technique becomes poroid, its withstand voltage properties is bad, therefore cause the distortion of PE Foam product owing to vehicle shakes in the process of transportation, the withstand voltage properties and the shock-absorbing capacity that therefore improve the PE Foam product are the major issues of being badly in need of solution at present.
In order to remedy the weak point of above-mentioned existing PE Foam withstand voltage properties and shock-absorbing capacity, the inventor has designed the present invention's " a kind of production technique of PE Foam ".
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art technical problem to be solved is: provide a kind of good pressure-resistant performance and production cost low PE Foam production technique.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of production technique of PE Foam comprises that agitating procedure, feeding drive operation, heat fused operation, foamed process and extrude operation, and wherein each operation is specific as follows,
Agitating procedure: new LDPE particle and circulation recovery LDPE material are mixed;
Feeding drives operation: solid-state LDPE particle enters through opening for feed, is done to drive being fed forward by spiral shell;
The heat fused operation: the electrically heated ring slowly is melted into liquid state with LDPE;
Foamed process: the polyethylene of high-temperature liquid state is foamed into cavernous structure under the katalysis of attached material monoresin and coal gas;
Extrude operation: the PE Foam after the foaming is extruded from die head after cooling off.
The PE Foam of extruding operation and being after the foaming is extruded from die head after cold pouring operation; Be provided with the quick-frozen operation in extruding the operation back, the quick-frozen operation be in the high temperature PE Foam when die orifice is extruded,, PE Foam can not foamed forms membrane structure on the moment of PE Foam outlet cooling PE Foam surface with strong cold air.Thereby the withstand voltage properties and the shock-absorbing capacity of PE Foam have been increased.
The production technique beneficial effect of a kind of PE Foam of the present invention is:
Improve the PE Foam surface tissue, existing cavernous structure has been changed over membrane structure, and then increased the withstand voltage properties and the shock-absorbing capacity of PE Foam.Because improved the shock-absorbing capacity of PE Foam material, so the product that has guaranteed client safety coefficient in transit.
Embodiment
The present invention implements like this:
A kind of production technique of PE Foam comprises that agitating procedure, feeding drive operation, heat fused operation, foamed process and extrude operation, wherein
Agitating procedure: new LDPE particle and circulation recovery LDPE material are mixed;
Feeding drives operation: solid-state LDPE particle enters through opening for feed, is done to drive being fed forward by spiral shell;
The heat fused operation: the electrically heated ring slowly is melted into liquid state with LDPE;
Foamed process: the polyethylene of high-temperature liquid state is foamed into cavernous structure under the katalysis of attached material monoresin and coal gas;
Extrude operation: the PE Foam after the foaming is extruded from die head after cooling off.
The PE Foam of extruding operation in addition and being after the foaming is extruded from die head after cold pouring operation; Be provided with the quick-frozen operation in extruding the operation back, the quick-frozen operation be in the high temperature PE Foam when die orifice is extruded,, PE Foam can not foamed forms membrane structure on the moment of PE Foam outlet cooling PE Foam surface with strong cold air.
The above, it only is the production technique preferred embodiment of a kind of PE Foam of the present invention, be not that technical scope of the present invention is imposed any restrictions, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention above any trickle modification, equivalent variations and modification that embodiment did.
