Preparation process of decorative plate containing polyurethane thermal insulation layer
The invention discloses a preparation process of a decorative plate containing a polyurethane thermal insulation layer. The preparation process comprises the following specific steps that a support isolation layer is soaked in an ethylenediamine solution, then the support isolation layer is fished out to wipe off redundant ethylenediamine on the surface, then the wiped support isolation layer is fixed below a mold, and a polyurethane material to be foamed is injected into the mold to obtain a thermal insulation support plate; and the thermal insulation support plate is soaked in 3-(2, 3-epoxypropoxy) propyltrimethoxysilane and then fished out to be dried, the bottom face of the decorative layer is coated with a layer of epoxy resin adhesive, then the decorative layer is bonded to the surface of the support isolation layer of the hydrophobic thermal insulation support plate through the epoxy resin adhesive, and the decorative plate is obtained. According to the preparation process, thehigh-strength support isolation layer is arranged between the thermal insulation layer and the soft porcelain decoration layer, the strength of the decorative plate can be improved, the decoration layer can be directly torn down after being used for a period of time, a new decoration layer is pasted again, no decoration layer remains on the surface of the torn-down supporting isolation layer, andsecondary pasting is not affected.
本发明公开了一种含有聚氨酯保温层的装饰板制备工艺，具体制备过程如下：将支撑隔离层乙二胺溶液中浸泡后捞出擦拭去表面多余的乙二胺，然后将擦拭后的支撑隔离层固定在模具下面，然后将待发聚氨酯料注入模具，得到保温支撑板；将保温支撑板在3‑(2,3‑环氧丙氧)丙基三甲氧基硅烷中浸泡后捞出烘干，在装饰层的底面涂布一层环氧树脂粘合剂，然后将装饰层通过环氧树脂粘合剂粘合在疏水保温支撑板的支撑隔离层表面，得到装饰板。本发明通过在保温层和软瓷装饰层之间设置一层高强度的支撑隔离层，能够提高装饰板的强度，并且在使用一段时间后可以直接撕下重新粘贴新的装饰层，并且撕下后支撑隔离层表面不会有装饰层残留，不影响二次粘贴。
