Abstract
The utility model relates to a tensile reinforced membrane, comprising a plastic membrane and the flexible tensile banding material compounded in the plastic membrane. The plastic membrane is composed of an upper layer plastic membrane and a lower layer plastic membrane heat sealed together. The flexible tensile banding material is a fiber bundle or a fiber rope, fibrage belt, flexible metal wire, flexible metal rope, and flexible metal band. The tensile reinforced membrane not only has the characters of damp proof, dust proof, water proof, soft, etc. , as the common plastic membrane, but also has high tensile strength, and can be used for making product packaging bag and various bags, in particular applied to the balloon membrane reinforcing band for the high altitude balloon.
Description
Technical field
The utility model relates to a kind of material, particularly a kind of plastic material with stronger tensile strength.
Background technology
The high-altitude scientific balloon is made by the ball membrane material, but because balloon will carry scientific experiment instrument or a detection instrument, makes balloon will bear heavier load, and this just requires to constitute, and the ball membrane material of balloon is in light weight, intensity is high, and stronger tensile strength be arranged.Price is low because plastic sheeting has, weight is relatively light and flexibility is good, relatively be fit to make aerostat, but its tensile strength of plastic film material is lower, can not directly make balloon with plastic sheeting.
In addition,, often be used to make packaging material, for example be used for adorning chemical fertilizer, Na because plastics have characteristics such as good protection against the tide, waterproof, softness
2CO
3, NaOH, sugar, cement etc., preventing the cakings that make moist such as the said goods, or prevent that some products are because of making moist or dissolving, lost efficacy because of drenching with rain.But because plastic sheeting tensile strength is low, so when the product of particularly packing as packaging material more than tens kilograms, for example every bag of weight such as cement, chemical fertilizer is generally 40Kg or 50Kg, at this moment can only be used as packing inside bag, play effects such as waterproof, rainproof, protection against the tide, its outside also will be surrounded by the more intense packaging material of resistance to tension such as woven bag, to prevent in carrying, not Bales Off when storing, cause packing cost higher, also make packing of product technology more complicated.
The utility model content
The purpose of this utility model is to provide a kind of plastic sheeting with advantages of higher tensile strength, it is the tension strengthening membrane, this tension strengthening membrane can be used to the plastic film packaging bag making high-altitude balloon and do not have external packing, or as the reinforcement material of plastic membrane product, use has a extensive future.
The tension strengthening membrane that the utility model provides is made of plastic sheeting and the flexible tensile belt-shaped material that is compounded in the plastic sheeting.
Described plastic sheeting can be made of heat seal upper strata plastic sheeting and lower floor's plastic sheeting together.
The tensile belt-shaped material of described flexibility is at least two, is arranged in parallel between mutually.
Spacing between the described parallel flexible tensile belt-shaped material can equate, also can not wait.
Because plastic sheeting has certain ductility, the tensile belt-shaped material of described flexibility preferably can make it stressed more even with respect to described plastic sheeting displacement.
The tensile belt-shaped material of described flexibility can be fibre bundle or cordage, fiber woven belt, using flexible wire, flexible metal rope or flexible metal band.
Above-mentioned fiber can be dacron thread, and described fibre bundle can be at least 20 monofilament terylene.
This tension strengthening membrane is owing to be compounded with flexible silk ribbon between plastic sheeting, make originally that the lower plastic film material of tensile strength has had advantages of higher tensile strength, kept plastic sheeting softness, waterproof, moistureproof characteristics simultaneously again.This plastic sheeting both can be used for making the reinforcing band of aerostat, also can be used for making plastic film packaging bag, or as the reinforcement material of plastic film packaging bag, be used for adorning cement, chemical fertilizer or other products, and do not need other outer packaging bag, so can reduce packing cost, simplify packaging process, and packaging bag is reusable, has broad application prospects.
Description of drawings
Fig. 1 is a kind of structural representation of tension strengthening membrane of the present utility model;
Fig. 2 is the A-A profile of tension strengthening membrane shown in Figure 1;
Fig. 2 is the another kind of structural representation of tension strengthening membrane of the present utility model.
The specific embodiment
Be described further below in conjunction with the structure of the drawings and specific embodiments, to help understanding content of the present utility model tension strengthening membrane of the present utility model.
As shown in Figure 1, the tension strengthening membrane is made of four bundle dacron threads 2 in four parallel via holes in a plastic tape 1 and the plastic tape 1.As shown in Figure 2, plastic tape 1 is bonded into by upper strata sealed polyethylene plastic 11 and 12 heat seals of lower floor's sealed polyethylene plastic, four bundle dacron threads, 2 every bundles are that 65S/48F, specification constitute for the low extension of 7.5g/d high strength monofilament dacron product by 30 models, and the upper strata sealed polyethylene plastic between every bundle and lower floor's sealed polyethylene plastic heat seal are together.Monofilament terylene 2 can move in plastic tape 1, and four bundles are parallel to each other between the dacron threads 2 and spacing equates.The tension strengthening membrane of this band shape carries out the tension experiment according to GB GB 8947-88 " plastics standard compilation " with INSTRON 1122 type puller systems, in test condition is that the tensile fracture of the tension strengthening membrane of wide 38mm, a long 20mm is 100Kg under pulling force 200Kg/ pulling rate 100mm/min, the chart speed 40mm/minKg condition.This banded tension strengthening membrane can be under-60 ℃ of low temperature operate as normal, can weld the reinforcing band that constitutes balloon with the plastic sheeting of making balloon, make the real stressed position of the plastic foil material of balloon lean on this tension strengthening membrane to bear.Also can be used for plastic packaging bag, weld together the reinforcing band that becomes plastic packaging bag with plastic packaging bag.
Embodiment 2
As shown in Figure 3, be compounded with 8 bundles dacron thread 2 parallel to each other in the plastic sheeting 1 in the present embodiment, the spacing between the dacron thread is unequal.This tension strengthening membrane can be made packaging bag, and dacron thread wherein can be made transparent case and bag with different colors.
