Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a polyurethane insulation board. Referring to fig. 1, the polyurethane insulation board includes a substrate 1, polyurethane foam 3 and an aluminum foil 2, the substrate 1 includes a supporting portion 11, a first clamping portion 12 and a second clamping portion 13, and the first clamping portion 12 and the second clamping portion 13 are respectively disposed at two ends of the supporting portion 11 in the width direction. The first engaging portion 12 is bent to form an engaging block 121, and the second engaging portion 13 is bent to form an engaging groove 131. The second engaging portion 13 is bent to form extending grooves 132 on two sidewalls of the engaging groove 131, and the engaging block 121 is adapted to the extending grooves 132.

Referring to fig. 1 and 2, when the insulation boards are spliced, the clamping between the adjacent insulation boards can be completed by clamping the fixture block 121 of one insulation board in the clamping groove 131 of the other insulation board, so that the insulation boards are convenient and fast to use. The clamping block 121 is in interference fit with the clamping groove 131, the insulation board is not easy to separate along the length direction of the insulation board, the integrity of the insulation board after splicing is improved, and the probability of falling of a single insulation board is further reduced; meanwhile, the tightness degree between two adjacent insulation boards is improved, the heat conduction rate of the joint of the two adjacent insulation boards is reduced, the heat insulation performance of the insulation boards after splicing is improved, and the energy is saved.

The end of the first clamping portion 12 away from the supporting portion 11 is further bent to form a first extending edge 122, the end of the second clamping portion 13 away from the supporting portion 11 is further bent to form a second extending edge 133, and the first extending edge 122 and the second extending edge 133 are both parallel to the supporting portion 11. The first extending edge 122 extends towards one side far away from the second engaging portion 13 from one end far away from the supporting portion 11, and the second extending edge 133 extends towards one side of the first engaging portion 12 from one end far away from the supporting portion 11. One end of the second extending edge 133, which is far away from the second clamping portion 13, is bent towards one side, which is far away from the supporting portion 11, so that a first extending edge groove 134 is formed at the second extending edge 133, the first extending edge 122 is inserted into the first extending edge groove 134, and the first extending edge 122 abuts against the second extending edge 133.

The inner surface of the latch 121 defines a first card cloth cavity 124, a second card cloth cavity 135 is defined between the second extending edge 133 and the inner circumferential surface of the latch slot 131, and the aluminum foil 2 is embedded in the first card cloth cavity 124 and the second card cloth cavity 135. Polyurethane foam 3 fills between aluminium foil cloth 2 and base plate 1, so first card cloth chamber 124 department and second card cloth chamber 135 department all can be filled by polyurethane foam 3, and then has reduced the heat conduction rate of the junction of two adjacent heated boards, has improved the thermal insulation performance of the heated board after the concatenation finishes, has practiced thrift the energy.

The second extending edge 133 is pressed into a corrugated shape by a press machine, and wave crests and wave troughs of the corrugation are uniformly distributed along the length direction of the substrate 1; first extension limit 122 is kept away from the one end inflection of supporting part 11 and is formed back limit 123, is the first extension limit 122 inflection and be back limit 123 back, also presses the corrugate through the press on first extension limit 122 and the ripple edge, and the length direction equipartition setting of base plate 1 is also followed to the crest and the trough of this ripple, and first extension limit 122 is crisscross setting with the ripple on the second extension limit 133. When splicing the heat preservation boards, the clamping block 121 of one of the heat preservation boards is clamped in the clamping groove 131 of the other heat preservation board, and at the moment, the first extending edge 122 on one of the heat preservation boards and the second extending edge 133 on the adjacent heat preservation board are in a clamping state.

The implementation principle of a polyurethane insulation board in the embodiment is as follows:

when producing this polyurethane insulation board, earlier with the shaping of buckling of base plate 1, later spray polyurethane foaming agent on base plate 1, later inlay the both ends of 2 width directions of aluminium foil cloth and establish respectively in first card cloth chamber 124 and second card cloth chamber 135 to make aluminium foil cloth 2 adhere to on the polyurethane foaming agent, later polyurethane foaming agent foaming inflation forms polyurethane foam 3, polyurethane foam 3 compresses tightly the both ends of 2 width directions of aluminium foil cloth in first card cloth chamber 124 and second card cloth chamber 135 when expanding.

When splicing the heated board, peg graft in the draw-in groove 131 of another heated board along the length direction of base plate 1 with the fixture block 121 of one of them heated board, after the grafting finishes, first extension limit 122 card is gone into in first extension limit groove 134, and the ripple on first extension limit 122 and the ripple on the second extension limit 133 joint each other, two adjacent heated boards had both been difficult for sliding relatively along the width direction of base plate 1 this moment, also difficult sliding relatively along the length direction of base plate 1, the stability of the heated board after the concatenation has been improved. Because fixture block 121 and draw-in groove 131 are interference fit, polyurethane foam 3 all has the packing in first card cloth chamber 124 department and second card cloth chamber 135 moreover, so improved the inseparable degree between two adjacent heated boards, reduced the heat conduction rate of the junction of two adjacent heated boards, improved the thermal insulation performance of the heated board after the concatenation finishes, practiced thrift the energy.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
