一种用于补强板的粘结剂及其补强板
摘要：
一种用于补强板的粘结剂及其补强板，其粘结剂包括：饱和聚酯树脂A、饱和聚酯树脂B、TPU树脂、异氰酸酯和填充剂；所述饱和聚酯树脂A的玻璃化温度‑20‑10℃；饱和聚酯树脂B的玻璃化温度为40‑60℃；TPU树脂的玻璃化温度‑10‑20℃；所述饱和聚酯树脂A为结晶型树脂；其补强板，包括：绝缘薄膜层、油墨层和胶黏剂层。本粘结剂中，将饱和聚酯树脂A、饱和聚酯树脂B、TPU树脂(全称为热塑性聚氨酯弹性体)、异氰酸酯和填充剂配合使用，并严格限制饱和聚酯树脂A、饱和聚酯树脂B和TPU树脂三者的玻璃化温度，按上述的搭配即可制备出一种TPU层和PET层都有强粘结效果的胶黏剂层。
摘要（英）：

The invention discloses an adhesive for a reinforcing plate and the reinforcing plate thereof. The adhesive comprises saturated polyester resin A, saturated polyester resin B, TPU resin, isocyanate and a filler, wherein the glass transition temperature of the saturated polyester resin A is -20 to 10 DEG C; the glass transition temperature of the saturated polyester resin B is 40-60 DEG C; the glass transition temperature of the TPU resin is -10 to 20 DEG C; and the saturated polyester resin A is crystalline resin. The reinforcing plate comprises an insulating film layer, an ink layer and an adhesive layer. According to the adhesive, the saturated polyester resin A, the saturated polyester resin B, the TPU resin, isocyanate and the filler are matched for use, and the glass transition temperatures of the saturated polyester resin A, the saturated polyester resin B and the TPU resin are strictly limited; so an adhesive layer with a strongly-bonding TPU layer and a strongly-bonding PET layer can be prepared through the matching of the above components.
