Said inside panel medial surface and framework junction, railway carriage or compartment also are provided with glue-line.
Said inside panel medial surface also is provided with glue-line, and said railway carriage or compartment framework one side is connected with inside panel through glue-line.
The size of mesh opening of fiberglass gridding cloth is long 5 ~ 15mm, wide 5 ~ 15mm.
The spacing L=10 of the medial surface of said fiberglass gridding cloth and inside panel or exterior skin ~ 20mm.
Said core material is a hard polyurethane foam.
The said frp layer that is wrapped in the core outside soaks the unsaturated polyester curing molding by Blanket.
The material of said glue-line is a polyurethane structural glue.
Said railway carriage or compartment framework comprises frame and reinforced rib, and said reinforced rib two ends are connected with scuncheon respectively.
Said frp layer thickness is 2 ~ 3mm.
The present invention compared with prior art the invention has the advantages that:
The present invention adopts the glass fibre reinforced plastic integral skeleton, and intensity is high, in light weight, water resistance is good; Exterior skin and railway carriage or compartment framework obviously improve railway carriage or compartment slab integral intensity through the gluing integral body that is connected into of polyurethane structural in the plate of railway carriage or compartment; The exterior skin bonding plane has improved the bind strength between froth bed and the interior exterior skin with polyurethane structural glue in the plate of railway carriage or compartment; The unsettled fixing glass fibrous mesh cloth in inside panel surface has been avoided the big abscess of foam, cavity blemish, has improved railway carriage or compartment plate presentation quality and railway carriage or compartment plate intensity.This new structure railway carriage or compartment plate heat-insulating property is good, and water resistance is good, and is in light weight, and intensity is high, and cost is low, has good proper value.
The present invention overcomes the deficiency of existing railway carriage or compartment plate structure technology, and from heavy and light, high insulating effect, water resistance is strong, structural strength is high, outward appearance is good.

The specific embodiment
Like Fig. 1,2, shown in 3; The present invention includes exterior skin 1, the inside panel 2 of railway carriage or compartment plate; Medial surface at exterior skin 1, inside panel 2 is equipped with glue-line 3, and glue-line 3 adopts polyurethane structural glue, is bonded with railway carriage or compartment framework 4 between two glue-lines 3; Railway carriage or compartment framework 4 comprises frame 5 and reinforced rib 6, frame 5 be positioned at railway carriage or compartment framework 4 around; Reinforced rib 6 (among Fig. 1 being four) is vertical to be provided with, and two ends connect (generally adopting bonding way) between frame 5 up and down.
As shown in Figure 4, form several cavitys 10 in the middle of the railway carriage or compartment framework 4, be exactly to surround cavity 10 in fact by frame 5 and reinforced rib 6.Frame 5 is identical with the structure of reinforced rib 6, and is as shown in Figure 5, all adopts hard polyurethane foam to do core 7, outer parcel frp layer 8, and frp layer 8 soaks the unsaturated polyester curing molding for Blanket.During actual production, frame 5 can be divided into plurality of sections with reinforced rib 6 to be made respectively, then according to the bonding successively formation of the true form railway carriage or compartment framework 4 of frame 5 and reinforced rib 6.The also unsettled one deck 10mm*10mm fiberglass gridding cloth 9 that is fixed with in glue-line 3 left sides of inside panel 2 one sides, fiberglass gridding cloth 9 and the inboard spacing L=10 ~ 20mm of inside panel.Fiberglass gridding cloth 9 is positioned at railway carriage or compartment framework 4 formed cavitys 10.
In cavity 10, charge into polyurethane at last, be full of whole cavity 10 until final polyurethane foaming foam 11.
Manufacturing process of the present invention is following:
The first step: adopt hard polyurethane foam to do core 7; Outer wrapped multiple Blanket is made frame 5 and reinforced rib 6, uses mould to be prefabricated into glass fiber reinforced plastic shapes by the cross sectional shape of frame 5 and reinforced rib 6, then according to frame 5 and the reinforced rib 6 bonding one-tenth general frames of various railway carriage or compartments plate gauge lattice size with moulding; Form van cooler insulation railway carriage or compartment framework (being railway carriage or compartment framework 4); This skeleton can reduce railway carriage or compartment framework weight, improves railway carriage or compartment plate heat-insulating property, improves railway carriage or compartment framework water resistance.
Second step: will be incubated the first hacking cleaning of the inboard bonding plane of exterior skin 1,2 in the plate of railway carriage or compartment; Evenly be coated with one deck polyurethane structural glue (being glue-line 3) then; The bind strength of exterior skin in isocyanurate foam and the railway carriage or compartment plate obviously improved railway carriage or compartment plate intensity when this method can improve foaming.
The 3rd step: before foaming, at the unsettled fixedly one deck of inside panel 2 inside faces 10mm*10mm fiberglass gridding cloth 9.When foaming, be prone to produce bulla, cavity blemish at the foam flow process in the past; And the present invention is through adopting fiberglass gridding cloth 9; Make foam through fiberglass gridding cloth 9 time, broken bubble, even bubble, thereby avoid the froth bed of railway carriage or compartment intralamellar part foaming bigger abscess, cavity to occur, avoid being incubated railway carriage or compartment plate outside face and the bulge defective occurs; Improve railway carriage or compartment plate presentation quality, also improve the structural strength of railway carriage or compartment plate froth bed.
The 4th step: after exterior skin 1 and railway carriage or compartment framework 4 each faying face are coated with that polyurethane structural is gluing to connect curing, be bonded to integral body.Exterior skin 1,2 can be used glass epoxy, aluminium sheet, stainless steel sheet or color steel etc., structure highly versatile in the plate of railway carriage or compartment.
The 5th step: on massive plate compression machine template, place exterior skin 1, glass fibre reinforced plastic integral railway carriage or compartment framework 4, fiberglass gridding cloth 9, inside panel 2 in order; After getting into massive plate compression machine heating and molding after the plate perimeter die of fastening railway carriage or compartment; Utilize high pressure foaming machine in the cavity 10 of railway carriage or compartment framework 4, to inject the polyurethane foam material; Insulation, pressurize, curing aftershaping form the present invention.
Need to prove: also only establish glue-line 3 on the exterior skin 1, do not establish glue-line 3 at inside panel 2, only establish glue-line 3 in inside panel 2 and railway carriage or compartment framework 4 junctions, glue-line 3 is bonded together inside panel 2 and railway carriage or compartment framework 4; Also can realize the object of the invention equally at the inboard unsettled fixing glass fibrous mesh cloth 9 of exterior skin; The sizing grid of fiberglass gridding cloth 9 also can be 15mm*15mm, 5mm*5mm, and the width range of grid is 5 ~ 15mm, and the length range of grid also is 5 ~ 15mm.Approximate variation so also drops in protection scope of the present invention.
