Problems solved by technology

PVC is a straight-chain molecule with a short molecular chain and low melt strength. During the process of bubble nuclei expanding into bubbles, the melt is not enough to cover the bubbles, and the gas is easy to overflow and merge into large bubbles, which reduces the product quality of the foam sheet.
[0004] In the prior art, when using a PVC-skinned foam board, since there are skins on both ends of the PVC-skinned foamed board, the PVC-skinned foamed board has a certain strength, and the foam between the two skinned layers Vinyl chloride provides certain sound insulation, shock absorption and support properties for PVC-skinned foam boards, but when PVC-skinned foam boards are used as connectors, the nail-holding force between the connectors is small, and there is a gap between the connectors. The connection is low and the connection is not tight

Embodiment 1

[0037] Such as figure 1 and figure 2Shown: a kind of multi-layer composite board, comprises two PVC crust foam boards 11 and adhesive layer 12, and adhesive layer 12 is formed between PVC crust foam boards 11, and is bonded via adhesive layer 12 The bonding effect makes the PVC crust foam board 11 bonded to form a multi-layer composite board 10; the PVC crust foam board 11 includes a PVC foam board layer and a skin layer located on the upper and lower surfaces of the PVC foam board layer, and an adhesive layer 12 is coated between adjacent skin layers; the adhesive layer 12 has a thickness of 0.3 mm, and the adhesive layer 12 is formed by coating acrylic glue.

[0038] Compared with a single PVC foamed board, the multilayered composite board provided by the present application significantly enhances the nail-holding force of the multilayered composite board by using the superimposed crust layer, so that the multilayered composite board 10 not only has the advantages and disa...

Embodiment 2

[0041] As shown in the figure, the content of this embodiment is basically the same as the structure of Embodiment 1, and the similarities will not be repeated. The difference is:

[0042] PVC crust foam board, including the following components: polyvinyl chloride resin powder 60kg, modified wood wool 30kg, stabilizer 1kg, lubricant 1kg, foaming agent 0.1kg;

[0043] The stabilizer is a composite lead stabilizer; the foaming agent is composed of a yellow foaming agent and a white foaming agent, and the yellow foaming agent is azodicarbonamide, azobisisobutyronitrile, nitroso foaming agent or acyl Hydrazine foaming agent; white foaming agent is sodium bicarbonate, ammonium bicarbonate, ammonium carbonate or azide compound, the mass ratio of yellow foaming agent and white foaming agent is 1:1 ~ 1:4; lubricant is Stearic acid, stearic acid esters, stearic acid alcohol compounds, stearic acid amides, fatty acid metal soaps, polyethylene wax, paraffin wax or oxidized polyethylene....

Embodiment 3

[0054] The content of this embodiment is basically the same as that of Embodiment 2, and the similarities will not be repeated. The difference is:

[0055] PVC crust foam board, including the following components: polyvinyl chloride resin powder 67kg, modified wood wool 35kg, stabilizer 1.5kg, lubricant 1.5kg, foaming agent 1kg.

Abstract

The invention relates to the technical field of PVC crust foaming boards, and particularly relates to a multi-layer composite board. The multi-layer composite board at least comprises two PVC crust foaming boards and an adhesive layer, wherein the adhesive layer is formed between the two PVC crus foaming boards, and the PVC crust foaming boards are adhered due to the adhesive effect of the adhesive layer to form the multi-layer composite board. Therefore, compared with the single PVC foaming board, the multi-layer composite board has flame-proofing, sound isolation, damping and other performance of the PVC foaming board, the connection performing of the multi-layer composite board serving as a connector is reinforced, the adhesive layer among multiple layers of PVC foaming boards can achieve the adhesion effect, the formed adhesion layer has certain elasticity, an opposite acting force for extruding a bolt can be generated at the joint between the adhesion layer and the bolt, and the nail-holding power of the multi-layer composite board can be further improved.
