The invention discloses a light-transmitting interior high-frequency embossed PU material for vehicles and a preparation method thereof.The PU material comprises a surface treatment layer, a PU surface layer, a PU light-transmitting layer, a pattern light-transmitting layer, a PU light-transmitting bottom layer and a base cloth layer which are sequentially arranged, and the PU light-transmitting layer and the PU light-transmitting bottom layer each comprise, by weight, 80-120 parts of a component A, 30-50 parts of a first flame retardant, 0.5-1.5 parts of a bridging agent and 50-90 parts of a component B; the component A is composed of 80-90% of hydroxyl polyol resin, 10-20% of a second flame retardant and 0.01-0.1% of a catalyst; and the component B is polyisocyanate. According to the PU material disclosed by the invention, the PU light-transmitting layer and the PU light-transmitting bottom layer have good ductility, so that abnormal phenomena such as bubbling and dissolving of the light-transmitting layer are avoided in a laminating process, and the prepared PU material has good light transmission.
本发明公开了车用透光内饰高频压花PU材料及其制备方法,PU材料包括依次设置的表面处理层、PU面层、PU透光层、图案透光层、PU透光底层和基布层,其中:PU透光层和PU透光底层均包含如下重量份计的原料:A组分80‑120份、第一阻燃剂30‑50份、架桥剂0.5‑1.5份、B组分50‑90份;A组分由80‑90%羟基多元醇树脂、10‑20%第二阻燃剂和0.01‑0.1%催化剂组成;B组分为多异氰酸酯。本发明的PU材料中PU透光层和PU透光底层具有良好的延展性,使其在贴合过程中避免出现鼓泡,溶解透光层等异常现象,且制备的PU材料具有良好的透光性。
