A kind of protective packaging adhesive plaster
Technical field
The utility model relates to the protective packaging material, particularly a kind of protective packaging adhesive plaster.
Background technology
Existing packing is the elastomeric materials such as surface coverage natural gum at framework materials such as cotton, polyvinyl cloth, polyamide fabric, woven dacron or nonwoven polypropylene fabric, neoprene, chlorosulphonated polyethylene, NBR, butyl rubber, poly-urethane rubber with various adhesive plasters, or the plastics fat such as polyvinylchloride, polyurethane plastics, through tri-roll press machine or four-roll calender calendering, process.
The utility model content
The purpose of this utility model is to have adhesive plaster deficiency in use procedure after making packing container for protective packaging now in order to overcome, and provide a kind of protective packaging adhesive plaster, this adhesive plaster physical property is good, air-tightness good, and possesses anti-dust, anti-salt fog, rainproof and the function such as anti-puncture and anti-tear.
The technical scheme that realizes the utility model purpose is:
A kind of protective packaging adhesive plaster, it is on by in-seam rack-layer and rubber layer and lower rubber layer form on in-seam rack-layer surface pressure is prolonged common calendering adhesive plaster, the anti-puncture layer of compound one deck forms.
Described anti-puncture layer is bright and beautiful silk or woven dacron.
The utility model has the advantages that: not only physical property is good, air-tightness good but also it is anti-dust to possess for the adhesive plaster of this structure, anti-salt fog, rainproof and the function such as anti-puncture and anti-tear; be mainly used under particular surroundings and rough weather; the inside and outside packing of special equipment, weapon etc. etc.; article in the protection package packaging container are avoided the damage of physics or chemical factor, significant to the packing protection of some special materials article.This technique can effectively avoid the protective packaging container use and transportation in easily collide with extrusion damage and wearing and tearing, occur in use that deformity weares and teares, affect protective packaging container service life.
The accompanying drawing explanation
The common adhesive plaster structural representation that Fig. 1 is prior art;
The structural representation that Fig. 2 is the anti-puncture protective packaging adhesive plaster of the utility model.
In figure: 1. 4. times rubber layers of rubber layer 3. in-seam rack-layer on anti-puncture layer 2..
The specific embodiment
A kind of manufacturing process of protective packaging adhesive plaster, its technological process is:
(1) first in-seam rack-layer 3 and the anti-puncture layer of bright and beautiful silk 1 being sticked with glue to agent is processed;
(2) adopt upper rubber layer 2 and the lower rubber layer 4 that tri-roll press machine is good by heat refining to roll on in-seam rack-layer 3, rolled the rear clean shield of drying that adopts and batched;
(3) by the anti-puncture layer 1 of handling well and the adhesive plaster batched with shield, on drum vulcanizer, carry out compound, anti-puncture layer 1 is positioned over the top of in-seam rack-layer 3 adhesive plasters, guarantee smooth corrugationless, the overlapping drum vulcanizer inlet point of putting into then, vulcanized drum rotate carry it in vulcanizer compound.Compound tense drum vulcanizer speed from slow to fast, last steady speed.Drum vulcanizer wire tape range of pressure 5~30MPa.Adhesive plaster compound tense vulcanized drum temperature is no more than 100 ℃.
(4) compound completing, compound adhesive plaster, through cooling, upper separant, cleaning, is put into horizontal steam vulcanization (cure) tank and is vulcanized.
(5), after having vulcanized, both can be used as half-blank through washing cloth, after the step such as oven dry, optical check and mail to workshop cutting moulding.After moulding completes, be up to the standards and both can be used as the certified products sale.
