Abstract
The present invention discloses a kind of vibration-resisting, heat insulating, moistureproof and chemical corrosion resisting case and bag material, which is formed through compounding one EVA material layer and one netted facing material layer. The case and bag material with compounded EVA material and netted facing material has raised wear resistance. In order to improve some performances, the case and bag material may also have some additive, including diluent, thickener, plasticizer, stuffing, antiager, etc. added. For example, proper amount of butyl rubber may be added to raise cold resistance, small amount of peroxide may be added to raise the heat resistance, and cheap polypropylene may be added to lower cost.
Description
Technical field
The present invention relates to a kind of box material.
Background technology
Big case and bag can be divided into soft case and hard case two big classes by the difference of its material.Hard case comprises ABS (styrene polymer) case and PP case (injection moulding), and soft case generally just is meant EVA (high density foaming) case.The ABS material has characteristics such as nontoxic, tasteless, that water absorption rate is low, has good comprehensive physical and mechanical properties and lustrous surface etc., and is easy to machine-shaping.
Chinese patent application CN03151147.3 discloses a kind of Case outer-shell material, it is characterized in that: compound polycarbonate film outside ABS sheet material.
Chinese patent application CN93108057.6 discloses the case and bag composite of a kind of soft or hard case combination.Be to be that the two sheet material that closely combines of ABS material constitutes for the textile fabric internal layer by skin.
But selected ABS and PP case on the present case and bag, though have moistureproof anti-characteristics of pressing, poor heat resistance, and inflammable.And general A BS/PP case weight is big, and retractility is poor.
EVA (ethene-one vinyl acetate copolymer) is a kind of meltability polymer that does not need solvent, not moisture 100% solid, is solid at normal temperatures, and heating and melting can flow and liquid that have certain viscosity, i.e. gluing body to a certain degree becoming.EVA PUR after the fusion is the adhesive that light brown is translucent or this is white.The composition of EVA PUR is made up of basic resin (ethene and vinyl acetate polymer), tackifier, viscosity-controlling agent, antioxidant and cold-resistance agent, antiheat agent etc.
EVA has advantages such as good buffering, antidetonation, heat insulation, moistureproof, resist chemical, and nontoxic, do not absorb water.The EVA product of rubber and plastic can shape through design, and its shockproof properties is better than polystyrene traditional expanded materials such as (foams), and compliance with environmental protection requirements.With respect to Shockproof packaging can cut, moulding; Because of density variation is bigger, purposes more widely can also be arranged.
EVA has following characteristics:
Resistance to water: airtight foam structure, do not absorb water, protection against the tide, water resistance is good.
Rotproofness: the corrosion of chemicals such as sea water resistance, grease, acid, alkali, antibiotic, nontoxic, tasteless, pollution-free.
Processability: non junction, and be easy to carry out hot pressing, cut out, processing such as gluing, applying.
Against shock: resilience and tension stress height, toughness is strong, 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 tan by the sun.
Sound insulation: airtight abscess, soundproof effect is good
High nearly 1 times of the strength ratio cotton of polyster fibre, higher 3 times than wool, so dacron is durable, or hear resistance and heat endurance are best in the synthetic fibers.Also have excellent abrasion resistance, be only second to polyamide fibre.Terylene is as the clothing fiber, often with terylene and various fiber blend or interweave, is widely used in various dress materials and ornament materials.
Summary of the invention
The objective of the invention is for the box material of a kind of antidetonation, heat insulation, moistureproof, resist chemical is provided.
To achieve these goals, the technical solution of the utility model is such:
A kind of box material is characterized in that: described material is to be combined by EVA (ethene-one a vinyl acetate copolymer) material and a netted lining.
Further, described netted lining can be the eyelet fabric of dacron thread braiding.
Further, described netted lining also can be the eyelet fabric of nylon yarn establishment.
Further, described material is to be to form by high temperature compacting by EVA and netted lining.
Further, described material makes EVA and netted lining compound by adding a soluble film in the high temperature pressing process.
Further, generally about 150 ℃, the time is 5-25 second to the temperature of described compacting, and pressure is about 7KGS.
EVA (ethene-one vinyl acetate copolymer) is a kind of not moisture, does not need the solid meltability polymer of solvent.EVA is a solid at normal temperatures, is heated to fusion after the uniform temperature, becomes and can flow and existing close-burning liquid.Be generally solid at normal temperatures, fusion is the liquid adhesive when being heated to a certain degree, in case be cooled to below the fusing point, will become solid (the sclerosis back is for solid block) rapidly, and easily keeping is deposited.Quick solidifying, adhesion are strong, and glue-line has certain pliability, and certain degree of hardness is arranged again.
In addition, in order to improve the performance of some aspect, also can add the other additive and be mainly diluent, tackifier, plasticizer, filler and antiaging agent etc.For example, add an amount of butyl rubber to improve cold resistance; Add a spot of peroxide to improve hear resistance; Add cheap polypropylene to reduce cost etc.
Description of drawings
Further specify the present invention below in conjunction with the drawings and specific embodiments.

The case and bag embodiment schematic diagram that Fig. 2 makes of box material of the present invention
The specific embodiment
The softening point of EVA PUR generally should could soften and begin molten moving more than 80 ℃ when promptly being heated to 80 ℃.This temperature and effect only are the temperature of PUR fusion, make it reach the degree that can cohere, could use when heating-up temperature also will rise to 130 ℃～180 ℃.
Concrete production technology is: with the EVA sheet material, the dacron thread screen cloth adds soluble film by the high temperature equipment complex, and the temperature of pressing compound tense is about 150 ℃, and the time of pressing is controlled at 5-25 between second.
To be placed on compression moulding in the aluminum dipping form after above-mentioned EVA1 and the polyester fabric 2 compound (see figure 1)s, required time is 15-50 second, and the pressure during compression moulding is controlled at about 7KGS.
The box material that will produce with above-mentioned production technology is cut into the anter of case and bag, sews up with sewing machine, attached again with aluminium section bar as framework, attached with various accessories, be processed as required finished product at last, (see figure 2) is to use an embodiment schematic diagram of box material of the present invention.
Certainly; present embodiment is not limited to the utility model; to those of ordinary skill in the art; still can do multiple variation to present embodiment; therefore; every employing analog structure of the present utility model and similar variation thereof all should be listed the protection domain of protection domain claims of the present utility model in.
