Abstract

The invention discloses a blocking explosion-proof material in which an aluminum foil or an aluminum alloy foil is taken as a base material. The blocking explosion-proof material is characterized in that: a plurality of I-shaped incisions are uniformly formed on the surface of the base material; the I-shaped incisions are distributed in rows and columns; an angle between directions of two adjacent rows or columns of I-shaped incisions is 90 degrees; two inner fins of all the I-shaped incisions are bent 90 degrees in the same direction; and the surface of the base material is latticed. When the material is used for making a blocking explosion-proof material unit body, the bent inner fins form vertical interlayer supports; the supports are high in stability and difficult to collapse; furthermore, interlayer spaces among the unit bodies can be guaranteed; and the formed unit bodies are high in flurry degree and easily in accordance with the pot body replacement rate meeting the national standard requirement.

Description

A kind of block blast-proof materials

Technical field

The present invention relates to a kind of block blast-proof materials, be used for the raw MAT'L of the obstruct antibomb unit body of flammable and combustible liquids or gas reservoir.

Background technology

Existing flammable and combustible liquids or gas reservoir, especially petrol service station storage tank, its inner many fillings block blast-proof materials, mostly block blast-proof materials is to be drawn in the net to process through cutting by alloy foil, and commonly used is to be rolled into barrel-contoured cell cube.Separating anti-explosive material unit body is piled up in flammable and combustible liquids or gas reservoir, and solid with storage tank can prevent the storage tank blast that causes because of contingencies such as static, naked lights.Chinese invention patent " explosion-suppressing material that is used for combustible and explosive articles " (publication number CN1077172A) just fully discloses this technology contents.This material, when forming the tubular cell cube, netted aluminium foil interlayer does not support, and interlamellar spacing is little, and the loft of cell cube is little.And, because block blast-proof materials is immersed in the liquid dielectric of storage tank, can occur subsiding, form not by the space of block blast-proof materials filling on the top of storage tank, in this space, lost the obstruct explosion prevention function.In order to solve this technical matters; Chinese invention patent application " separating anti-explosive material unit body " (publication number CN1673608A) discloses a kind of separating anti-explosive material unit body; This cell cube is with the angle steel framework of encircling a city; The grid that has braided steel wire to become on the framework is filled with block blast-proof materials in framework, form separating anti-explosive material unit body.This separating anti-explosive material unit body, can prevent effectively that block blast-proof materials from producing in storage tank subsides, still; Because each cell cube all increases said frame; Make the production process of cell cube change, cost increases, simultaneously; Support frame takes up room, and make to fill storage tank behind the separating anti-explosive material unit body and can not satisfy in the national standard requirement about rate of displacement.When cell cube was changed, framework was also changed discarded in the lump, has both increased cost and has also caused waste.

US Pat " be used for container explosion protection (EXPLOSION PROTECTION SYSTEM FOR A CONTAINER " (patent No. 5000336); A kind of block blast-proof materials is disclosed in Fig. 7; Be employed in the sub-shape otch of cutting door on the aluminium foil; Bending forms the mode of interlayer support then, has possessed certain interlayer support effect.But because aluminium foil extremely thin (its thickness generally is 0.02mm), the bearing force of tabs is very little, still has collapse phenomenon with the tubular cell cube of this materials for support.

Summary of the invention

Technical matters to be solved by this invention; Be to overcome the defective that prior art exists, a kind of block blast-proof materials be provided, with the separating anti-explosive material unit body of material of the present invention; Can effectively guarantee reasonably (setting) interlamellar spacing; The interlayer loft of cell cube is big, and interlayer support is good, is difficult for subsiding.

The technical scheme that the present invention adopts is that adopting aluminium foil (alloy foil) is base material, it is characterized in that: the some I-shape otch of rectangular distribution on the said substrate surface; Said I-shape notching layer ranks distribute, and the I-shape cut-out direction of adjacent two row or two row differs 90 °; Two interior wings of all I-shape otch are all by 90 ° of equidirectional bendings, and it is latticed that substrate surface is.

During with material separating anti-explosive material unit body of the present invention; Interior wing by bending forms orthogonal interlayer support; The good stability of this support is difficult for subsiding, and can guarantee the interlamellar spacing of cell cube; The loft of the cell cube that forms is good, the tank body rate of displacement that the national standard that is content with very little requires.

Description of drawings

Fig. 1 is an I-shape otch distribution schematic diagram on the substrate surface of the present invention;

Fig. 2 is the interior wing wrap direction scheme drawing of I-shape otch on the substrate surface of the present invention;

Fig. 3 is a block blast-proof materials structural representation of the present invention (overlooking).

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is explained further details.

The present invention can adopt disclosed various aluminium foils of prior art or alloy foil to do base material 1, and the material major requirement of base material is to satisfy that ductility requires, heat conductivility requires, the electrostatic conductive performance requirement.As shown in Figure 1, at first on base material, cut I-shape otch 2, the I-shape otch is ranks and distributes; The double-tee direction of adjacent two row/row differs 90 °; As shown in Figure 2 then, the interior wing 3 of I-shape otch by 90 ° of equidirectional (face that makes progress to base material or downward face) bendings, is formed interlaced support; Substrate surface forms latticed, and is as shown in Figure 3.

Also can adopt the mode of die cut, disposable die cut forms the bending of I-shape otch and interior wing.

When making separating anti-explosive material unit body with the present invention, latticed base material is rolled into tubular naturally, the interior wing of bending forms staggered the support naturally, and layer stability is good, and cell cube is difficult for subsiding, and can satisfy the shop characteristic requirement of separating anti-explosive material unit body preferably.

Claims

1. block blast-proof materials, adopting aluminium foil or alloy foil is base material, it is characterized in that: the some I-shape otch of rectangular distribution on the said substrate surface; Said I-shape notching layer ranks distribute, and the I-shape cut-out direction of adjacent two row or two row differs 90 °; Two interior wings of all I-shape otch are all by 90 ° of equidirectional bendings, and it is latticed that substrate surface is.
