Abstract
The invention provides a metal-polyurethane-FRP (fiber reinforced plastic) composite pipe, and aims to solve the problems that a conventional FRP pipeline is relatively weak in flame retardancy, antistatic property and rigidity. The metal-polyurethane-FRP composite pipe comprises a lining layer, a heat insulation layer consisting of polyurethane foam and a metal layer from inside to outside, wherein the lining layer is formed by crosswise laying annular glass fiber yarns and longitudinal glass fiber yarns; an inner cavity with an annular section is formed by the lining layer and the metal layer; the heat insulation layer is positioned in the inner cavity; a plurality of through holes are formed in the metal layer. According to the metal-polyurethane-FRP composite pipe, the heat insulation layer of the metal-polyurethane-FRP composite pipe is molded after polyurethane foam rubber which is injected into the inner cavity through the through holes is solidified and the inner cavity is full of the polyurethane foam rubber, so that the inside and outside bonding strength is greatly enhanced; meanwhile, the effects of heat preservation and heat insulation are achieved; the metal-polyurethane-FRP composite pipe is particularly suitable for liquid conveying pipelines deeply buried in the ground during urban construction. The metal-polyurethane-FRP composite pipe has the advantages of high heat preservation performance, high rigidity and long service life.
Description
Technical field
The present invention relates to a kind of Glass Steel Tube, particularly relate to a kind of Glass Steel Tube of MULTILAYER COMPOSITE, belong to fibre resin complex technique field.
Background technique
Glass Steel Tube is used for buried use, and affect by negative pressure of vacuum in earthing, ground dynamic load and pipe etc., easily produce deflection deformation, simultaneously by the impact of clammy environment, its heat insulation effect is also poor.And pure fiber reinforced plastic pipe fire-retardant, antistatic, rigidity is all more weak.Improve the rigidity of pipeline, anti-static electricity property, general employing three kinds of modes: is the wall thickness improving merely pipeline, although this method can extend working time, uneconomical; Two is set up stiffening rib at body, thus ensures that pipeline wall thickness meets the requirement of interior pressure; Three is set up steel wire as inside liner at Glass Steel Tube inwall.Latter two mode requires higher to pipeline preparation process, does not also have good heat insulation effect.Therefore, people urgently expect a kind of good heat insulating, the Glass Steel Tube appearance that antistatic, crushing resistance is good.
Summary of the invention
For deficiency of the prior art, the invention provides that a kind of good heat insulating, rigidity are high, the reinforced glass fiber reinforced plastic composite pipe of long service life.
For achieving the above object, the invention provides a kind of metal-polyurethane-composite glass steel pipe, comprise thermal-protective coating, the metal layer of inside liner, polyurethane foam formation from the inside to the outside, inside liner is formed by hoop glass fiber yarn and the laying of longitudinal glass fiber yarn intersection, inside liner and metal layer form the inner chamber that cross section is ring, thermal-protective coating is arranged in inner chamber, and metal layer is provided with several through holes.In the present invention, thermal-protective coating is that to be full of inner chamber Post RDBMS through described through hole to the polyurethane foam sizing material of luminal perfusion shaping, significantly improves the heat-shielding performance of whole pipeline.
Further, in inside liner, hoop glass fiber yarn presses the circle distribution of pipeline, the axis being parallel of longitudinal glass fiber yarn and Glass Steel Tube.
The present invention compares with prior art, has following beneficial effect:
1, the present invention adopts inside liner to strengthen densification in pipe, and metal layer is in skin, plays the unlikely effect of disturbing bent distortion of protective conduit.
2, some through holes of being arranged by metal layer of the present invention, thermal-protective coating is solidify to form to the luminal perfusion polyurethane foam sizing material between inside liner and metal layer, combination of inner and outside power is strengthened greatly, play the effect of insulation simultaneously, be specially adapted to the liquid conducting pipes of buried underground in urban construction.
accompanying drawing explanation
Figure l is axial section structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the glass fiber yarn structure unfolded drawing of inside liner in Fig. 1;
Fig. 4 is the polyurethane foam structure unfolded drawing of thermal-protective coating in Fig. 1.
In above-mentioned accompanying drawing, 1 is inside liner, and 2 is thermal-protective coating, and 3 is metal layer, and 4 is hoop glass fiber yarn, and 5 is longitudinal glass fiber yarn.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1 to 4, the present embodiment metal-polyurethane-composite glass steel pipe, comprise inside liner 1, thermal-protective coating 2, metal layer 3 from the inside to the outside, first intersected by hoop glass fiber yarn 4 and longitudinal glass fiber yarn 5 and be laid to glass cross, brush resin on glass cross, above-mentioned steps is until meet the thickness requirement of glass fibre reinforced plastics repeatedly, and processing can obtain inside liner 1 further on this basis.As shown in Figure 3, in inside liner 1, hoop glass fiber yarn 4 presses the circle distribution of pipeline, the axis being parallel of longitudinal glass fiber yarn 5 and Glass Steel Tube.
Inside liner 1 and metal layer 3 form the inner chamber that cross section is ring, and metal layer 3 is provided with several through holes, and as shown in Figure 2, this thermal-protective coating 2 is that to be full of inner chamber Post RDBMS through described through hole to the polyurethane foam sizing material of luminal perfusion shaping.
The present invention adopts inside liner 1 to strengthen densification in pipe, and metal layer 3 is in skin, plays the unlikely effect of disturbing bent distortion of protective conduit.
Thermal-protective coating of the present invention utilizes polyurethane foam and resin, metal adhesive, and adhesive ability is very strong.The strength ratio natural timber of polyurethane foam is high, and as shown in Figure 4, its internal void, makes again the polyurethane foam as mesosphere serve the effect of insulation, be specially adapted to the liquid conducting pipes of buried underground in urban construction.
