Abstract
A kind of fire-retardant collapsible anticorrosive packaging film is made up of two-layer or three-decker, and internal layer contains the antirust agent to metal with anti-corrosion protection function, and intermediate layer and outer layer contain the fire retardant of anti-flaming function, plastic pellet of each layer containing heat shrinkable performance.The packaging film be by various raw material in certain species and ratio mixing after on double-deck or three-layer co-extruded film blowing device by uniform temperature condition and thickness proportion it is heated, coextrusion blow is formed, and is a kind of Multifunction anticorrosive metal, protective packaging material.This packaging film is heated collapsible, with rustless property it is excellent, pack fit, good airproof performance, fastening, fire-retardant and the characteristics of be easy to automation mechanized operation, it is economical and practical, anticorrosion of the products such as auto parts and components, plant equipment, hardware ＆ tools, metallurgic product, Aero-Space, electronic equipment, weaponry during storing and transporting, protective packaging are can be widely applied to, is a kind of virgin material that can be used for current metal protection packaging field.
Description
Technical field
The present invention relates to metal use packs membrane material, a kind of fire-retardant collapsible anticorrosive packaging film product and manufacture method.
Background technology
With the development of logistlcs technology and storing technology, new requirement, i.e. single-piece mass it is also proposed to metal rust preventing film packaging and pack, fasten packaging, unit package and automatic packaging, be not still adapted to the corresponding rush-resisting material of this demand at present.Shrink wrap is that one kind can be shunk in the case of being heated automatically, and the packaging material that can be shaped after cooling can form fixed, general unit package, can realize automating batch package, be widely used in the protective packaging of food, medicine, tableware etc..
While general metallic article rust prevention packaging demand is met; more also special character needs to consider; it is exactly for ultra-large type mechanized equipment and weaponry; such as large sized complete sets of equipment, aircraft, tank, panzer, warship etc. is sealed up for safekeeping or transportation and packing; requirement can not be fully met only with the film of contraction and anti-corrosion protection function; when reason is to carry out above-mentioned Large-Scale Equipment packaging operation; it is larger because equipping; must be packed using manual constriction, i.e., using the shrink wrapping mode of open firing.Simultaneously because equipment specification is very big, it is required that thin film strength is very high, hence in so that the thickness of packaging film is 2-4 times of common metal part packaging film, i.e. between 180-300 microns, the plastic sheeting of this thickness under open firing state is likely to catch fire, and affects also to bring fire hazard while packaging operation.Simultaneously during Large-Scale Equipment is sealed up for safekeeping, transported, it is also possible to contact naked light, so as to bring the fire hazard after packing, jeopardize equipment safety.
Existing related application is shown in contrast 1：《Gas phase anticorrosive thin film of thermal contraction》CN 1796449A and contrast 2：《Trilaminar co-extrusion thermal contraction resin film, production method and application process》CN 101318392A.
Contrast 1：CN
In 1796449A, claim 1 mentions vapor phase inhibitor 5-10%, the organic pigment 0.2-1% techniques be pure vapour phase inhibitor and organic pigment are mixed with plastics after direct extrusion-blown modling film forming, it is this directly that the mode of powder and plastic pellet hybrid process is infeasible in actual manufacture process, there is powder-grain separation problem, powder in hopper and disperse serious irregular production and quality problems in film, simultaneously for the performance of final products, such as heat sealability, physical strength, function etc. also has harmful effect.
The content of the invention
It is an object of the invention to provide a kind of brand-new fire-retardant collapsible anticorrosive packaging film and manufacture method, can overcome the defect in above-mentioned technology, it is available flame heating, for the anticorrosive packaging film of main equipment.
Fire-retardant collapsible anticorrosive packaging film, it is characterised in that (1) packaging film has inside and outside double-layer structure：Endothecium structure is made up of the anti-corrosion plastic master batch of LDPE, 3%～10% LLDPE, 5%～20% mLLDPE and 4%～10% that percentage by weight is 60%～88%, outer layer by 65%～80% LDPE, 5%～10% LLDPE, 5%～10% HDPE and 10%～15% flame retardant plastics master batch constitute；(2) packaging film has interior, domestic and abroad three-decker, endothecium structure by the LDPE that percentage by weight is 60%～88%, 3%～10%, the anti-corrosion plastic master batch composition of LLDPE, 5%～20% mLLDPE and 4%～10%, media layer damage by 55%～83% LDPE, 2%～5% LLDPE, 5%～10% HDPE, 5%～20% mLLDPE and 5%～10% flame retardant plastics master batch constitute, outer layer is made up of the flame retardant plastics master batch of 75%～85% LDPE, 5%～10% LLDPE and 10%～15%.Manufacture method：The product of two-layer or three-decker is obtained by the processing of double or three-layer co-extruded Blown-film line coextrusion blow.
Specific embodiment
With reference to embodiment, the present invention will be further described：
Embodiment 1
