Abstract
The invention relates to a thin-walled stainless steel-glass reinforced plastic composite pipe. The composite pipe comprises a thin-walled stainless steel outer pipe and a glass reinforced plastic core material arranged inside the stainless steel outer pipe, wherein the glass reinforced plastic core material is pipe body or a solid rod, the stainless steel outer pipe has a round or rectangular cross section or is a special-shaped pipe, or the cross section of the stainless steel outer pipe is in the shape of a hollow H to serve as an agricultural greenhouse framework, or a steel structure house beam column, or an explosion-proof bullet-proof pickproof fireproof door/window and the like. Due to the fact that the glass reinforced plastic is located inside the stainless steel pipe and the bending resistance, shear resistance and shock resistance of the stainless steel pipe are all far better than those of the glass reinforced plastic, the stainless steel and the glass reinforced plastic can not be damaged easily in general when applied with moderate shock externally, and then overall shock resistance is easily improved. Due to the excellent extendability of the thin-walled stainless steel, the stainless steel composite pipe can be bent into multiple shapes according to technology requirements. The temperature resisting range of the stainless steel is far wider than that of the glass reinforced plastic, and the inorganic glass reinforced plastic inside the pipe is a non-combustible A-grade material.
Description
Technical field
The present invention relates to a kind of lighter weight, highly stronger thin-wall stainless steel-composite glass steel pipe rod, can be applicable to agricultural greenhouse skeleton, steel house beam column, Anti-explosion buttlet-proof anti-theft and fireproof door, freeway guardrail, railing, automobile buffer beam, vehicle car girder, dock skeleton, high strength decorative tube.
Background technique
Existing stainless steel-composite glass steel pipe, is the composite pipe that frp lining Stainless Steel Tube forms, and is a kind of conventional internal and external anti-corrosive multiple tube at present.Its deficiency is: the outside of glass fibre reinforced plastics in Stainless Steel Tube, and cause composite pipe being subject under external impacts, glass fibre reinforced plastics easily breaks or is impaired, adopts bending resistance of thin-wall stainless steel, antitorque, anti-shearing span low; In addition, glass fibre reinforced plastics can be narrower in the temperature range limit of normal operating condition, be generally-50 ℃ to 200 ℃, glass fibre reinforced plastics is when contiguous its limiting temperature point, the indexs such as its intensity, Young's modulus can significantly reduce.And then affect the intensity of whole composite pipe, and its bending resistance, antitorque, shear strength, ageing-resistant, shock resistance and Young's modulus are declined to a great extent, burning grade is below B2 level.
How to solve the problems of the technologies described above, be the technical barrier of related domain.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of simple in structure, light weight is high-strength, weather-proof, resistance to compression, anti-shearing, bending resistance, antitorque, shock resistance is strong and be the thin-wall stainless steel-composite glass steel pipe of A level in the stable performance of limiting temperature point, the grade of burning.
In order to address the above problem, the invention provides a kind of stainless steel-unorganic glass steel pipe, comprising: stainless steel outer tube and the FRIM core or the reinforced plastic glass fibre that are filled in this stainless steel outer tube increase plastic core material.
Further, described stainless steel outer tube is thin-wall stainless steel, and wall thickness is 0.2 ㎜-5 ㎜, and glass fibre reinforced plastics core is body or solid bar, described glass fibre reinforced plastics core is magnesia oxychloride cement and glass fibre compound inorganic glass fiber reinforced plastic, or the glass fiber reinforced plastic that is composited of glass fibre and synthetic resin.
If described glass fibre reinforced plastics core is hollow body, the inwall of this body is also provided with plastic tube or metal tube.
Further, stainless steel outer tube is that section is the Stainless Steel Tube of circle or rectangle, or steel tubing in different shapes.Steel tubing in different shapes is the general name of the seamless steel pipe of other sectional shapes except pipe.Steel tubing in different shapes can be divided into oval steel tubing in different shapes, triangle steel tubing in different shapes, hexagon steel tubing in different shapes, rhombus steel tubing in different shapes, octagon steel tubing in different shapes, semicircle steel tubing in different shapes, inequilateral hexagon steel tubing in different shapes, the quincunx steel tubing in different shapes of five lobes, lenticular steel tubing in different shapes, double concave steel tubing in different shapes, melon seeds shape steel tubing in different shapes, conical steel tubing in different shapes, corrugated steel tubing in different shapes etc.
Further, the section of described stainless steel outer tube is hollow I-shaped pipe, and its mechanical strength is better than that section is rounded, square tubular, the crossbeam in automobile buffer beam, vehicle car girder, dock skeleton.
Further: Stainless Steel Tube can select thin walled tube and glass fibre reinforced plastics core more than 0.2 ㎜ compound, increase substantially fire prevention, anti-shearing, bending resistance, antitorque, impact compressive strength and Young's modulus, reduce costs more than 50%.
Further: Stainless Steel Tube and FRIM core are compound, become high temperature resistant A level noncombustible material.
It when glass steel core is FRIM, is A level noncombustible material.
The present invention has positive effect with respect to prior art: in (1) thin-wall stainless steel-composite glass steel pipe of the present invention, FRIM (magnesia oxychloride cement gelatinization material and glass fibre composite curing), in Stainless Steel Tube, is A level noncombustible material.Because high-intensity inorganic glass reinforced plastic and outer wall Stainless Steel Tube are bonded into, therefore when being subject to the impact of outside general size, stainless steel glass steel pipe generally can be not impaired, so be beneficial to, improves whole fire prevention, shock resistance, anti-shearing, antitorque, resistance to flexure, raising Young's modulus performance; (2) stainless can temperature resistant range much larger than glass fibre reinforced plastics, when the limiting temperature point of ambient temperature adjacent glass steel, because glass fibre reinforced plastics is in Stainless Steel Tube, be that stainless steel plays certain buffer action, and the glass fibre reinforced plastics in pipe (especially solid glass fibre reinforced plastics core) the temperature temperature spots that reaches capacity is required consuming time longer, so the relative prior art of the performance of the glass fibre reinforced plastics in Stainless Steel Tube will be stablized manyly; (3), in the present invention, for example, when the low warm spot of the limit (-50 ℃) of adjacent glass steel, the hardness of glass fibre reinforced plastics does not reduce, and can increase on the contrary, just becomes fragile; And the Stainless Steel Tube of periphery can be protected the now glass fibre reinforced plastics of fragility just, and the overall performance of composite pipe is now substantially constant; Therefore when the low warm spot of the limit of adjacent glass steel, the indexs such as the Young's modulus of composite pipe of the present invention, durability and intensity are better than prior art.The technology of the present invention will, to meeting in stainless steel material suitable application area under same performance requirement, reduce costs more than 50%.
