According to the utility model, through polyethylene crosslinked materials of the foaming layer, the production base materials of the multilayer bag structure are all nontoxic high-molecular polymers, and the original structures of the base materials are changed by using crosslinking caused by that electric ion radiation acts on substances, so that the foaming layer has the advantages of no additive and no chemical residue and the like; in addition, the polyethylene crosslinked foam material layer also has the characteristics of high resilience, high temperature resistance, strong weather resistance, almost no change after being exposed outdoors for 20 hours, high bending strength and compression strength, and difficult deformation; the fabric layer of the multilayer bag structure ensures the colors and materials of bags; and the lining layer of the bag structure is mainly used for assisting in the product modelling, and achieves an effect of protecting the fabric layer of a product.

Description

Multilayer case and bag structure

Technical field

The utility model relates to a kind of case and bag, particularly a kind of Environmental Safety, high temperature resistant, weatherability, the multilayer case and bag structure of the advantage such as not yielding, wear-resisting.

Background technology

In the prior art, the case and bag that we commonly use generally comprise hard case and soft case two large classes, its middle finger EVA(high density expanded material) case, the resistance to water of this class EVA box material: airtight foam structure, do not absorb water, moistureproof, water resistance is good; Corrosion resistance: the corrosion of the chemicals such as sea water resistance, grease, acid, alkali, antibiotic, nontoxic, tasteless, pollution-free; Against shock: resilience and tension stress are high, and toughness is high, has good shockproof, shock-absorbing capacity; Heat insulating ability: heat insulation, heat-insulating and cold and low temperature performance excellent can be cold-resistant and the advantage such as tan by the sun, but it has the following disadvantages: jaundice of long duration, shrink and non-refractory, and easily distortion, durability degree is poor, and service life is short, and is not wear-resisting etc.; Another kind of case and bag are hard casees, and its material is ABS, and the tank surface of making is hard, and its advantage is light weight, but its poor heat resistance, and inflammable, the weatherability of ABS is poor simultaneously, under the effect of ultraviolet light, easily produce degraded, after outdoor half a year, the impact strength drop by half; The bending strength of ABS and compressive strength are relatively poor in addition.The color printing general expression of present case and bag on the market directly is printed on the surface of precoat in addition, and color printing etc. are not lasting, are easy to peel off.Above-mentioned all be to manufacture the essential technical problems that solve of case and bag.

The utility model content

The purpose of this utility model be to solve in the above-mentioned box material of the prior art the soft case of EVA service time of a specified duration easy jaundice, shrink and non-refractory, easily distortion, durability degree is poor, and service life is short, the poor heat resistance of the not wear-resisting and hard case of ABS, and inflammable, the weatherability of ABS is poor simultaneously, easily produces degraded under the effect of ultraviolet light, after outdoor half a year, the impact strength drop by half; The multilayer case and bag structure of the advantages such as deficiency and color printing that bending strength and compressive strength are relatively poor come off easily, and a kind of possess Environmental Safety, high temperature resistant, weatherability are provided, and is not yielding, wear-resisting, that color printing is lasting.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multilayer case and bag structure, it comprises oneself precoat, foaming layer, lining layer outside to inside, described precoat is sandwich construction, described foaming layer is the polyethylene crosslinked foaming material layer, and described lining layer is nylon cloth or terylene layer of cloth.

The beneficial effects of the utility model are: after adopting product of the present utility model, polyethylene crosslinked foaming material layer by foaming layer, it is produced base-material and is nontoxic high molecular polymer, the crosslinked original structure of base-material that changes of utilizing the electron ion radiation effects to produce in material, its have additive-free, without advantages such as chemical residuals, the polyethylene crosslinked foaming material layer also has the rebound performance height in addition, high temperature resistant, weatherability is strong, the 20h that is exposed to the sun out of doors is afterwards almost unchanged, bending strength and compressive strength are high, on-deformable characteristics; Two factors of case and bag color and material are directly embodied by the precoat with sandwich construction of being located at the foaming layer outside, and the precoat of described sandwich construction has guaranteed color and the material of case and bag; Described case and bag lining structure mainly is the moulding of subsidiary products, plays simultaneously the effect of protection product fabric.

As preferably, described precoat, foaming layer, lining layer have certain intensity by the hot-forming integral body that is connected to by the hot-forming case and bag structure that is composited, and have reduced simultaneously the use of additive and auxiliary agent, have reduced the interpolation of pollutant.

Further, described sandwich construction is made of fiber weaving cloth layer, adhesive film, color printing film, and the color printing layer in this sandwich construction has increased the aesthetics of case and bag, and adhesive film has increased the bonding force of color printing layer, so that color printing layer difficult drop-off, increased the service life of case and bag.

Further, described adhesive film is polypropylene or polyethylene plastic film or the adhesive of heating and melting, and described adhesive film is more convenient for the skin coating color printing layer in woven cloth, so that the outward appearance of case and bag is more attractive in appearance beautiful.

Further, described color printing layer is for to be printed on the outer field polypropylene of adhesive film or vinyon printing film with required pattern or anti-counterfeiting mark, having printed pattern or anti-counterfeiting mark color printing layer has increased the aesthetics of case and bag, simultaneously required pattern or anti-counterfeiting mark are printed on adhesive film skin afterwards compound upper polypropylene or vinyon printing film, have increased the persistence of color printing.

Compared with prior art, advantage of the present utility model is as follows: 1, Environmental Safety has reached the nontoxic standard of European Union environmental protection and China Compulsory 3C authentication; 2, in the precoat of sandwich construction the structure of fiber weaving cloth layer, adhesive film, color printing film so that, be compounded in the outer color printing layer difficult drop-off of fiber weaving cloth layer, increased the service life of case and bag; 3, described case and bag lining structure mainly is the moulding of subsidiary products, plays simultaneously the effect of protection product fabric.
