Description

一种无卤阻燃型覆铜板的制作方法
技术领域
本发明涉及电子材料技术领域,具体涉及一种无卤阻燃型覆铜板的制作方法。
背景技术
保护环境并与之和谐相处,已经成为全世界人们的共识,同时也成了印制线路的重大课题。电子材料对环境的影响越来越受到关注.欧洲和日本率先掀起覆铜板无卤化的进程。传统的高耐热适用于无铅制程的高Tg覆铜板采用卤素(Br等元素)作为阻燃剂,但这种物质在不完全燃烧的情况下会产生一种致癌物质-二噁英。因此,我司采用另一种含磷环氧树脂和邻甲酚醛环氧树脂来作为阻燃剂,同时可以满足阻燃要求,又符合环保要求。但该树脂固化后性脆,因此,改善无卤覆铜板的缺陷,开发对应的树脂组合物和增韧剂以满足市场需求,显得极为重要。
鉴于此,特提出本发明。
发明内容
针对现有技术中的上述不足,本发明提供的无卤阻燃型覆铜板的制作方法解决了现有酚醛树脂固化后性脆、熔融粘度相对高的问题。
为了达到上述发明目的,本发明采用的技术方案为:
一种无卤阻燃型覆铜板的制作方法,包括以下步骤:
(1)按重量份取50-60份含磷环氧树脂和190-200份邻甲酚醛环氧树脂加入高速搅拌机桶内, 再往其中加入50-60份PMA,将高速搅拌机桶推至高速搅拌机下,开启高速搅拌机。
(2)按重量份取40-50份端氨基液体橡胶、6-10份端羟基聚氨酯预聚体、6-10份封闭异氰酸酯及40-50份聚氨酯,混合搅拌后形成弹性体。
(3)将步骤(2)得到的弹性体加入到高速搅拌桶中,一边搅拌一边添加。
(4)按重量份取110-120份酚醛树脂、0.5-0.7份催化剂二甲基咪唑加入到步骤(3)获得的混合料中,持续搅拌,使其与所述混合料充分产生固化反应后形成胶水。
(5)用取样品抽取适量胶液到化验室中测试胶水的S/G(固化时间),此配方的胶水S/G范围在:300-320S,合格后进行下一步步骤。
(6)将玻璃纤维布放入浸满胶水的含浸槽,胶水通过管路泵进入到含浸槽中,然后把浸透胶水的玻璃布放入烘箱中,烘干后得到半固化片。
(7)将半固化片按照计划要求的厚度,搭配不同的半固片张数。堆叠好后送入组合室。
(8)将步骤(7)堆叠的半固化片覆上单面或者双面的铜箔,通过模具组合,组合好后送入热压机。
(9)利用高温使半固化片中树脂熔融,并于高压下将汽泡赶出,使树脂逐步硬化并与铜箔粘结。
(10)将压合好的基板裁掉边料,然后通过外观、厚度等检验后出货。
进一步地:弹性体添加完成后,转速不低于1000r/Min,搅拌时间不少于5H。
进一步地,步骤(4)中,持续搅拌不低于5H。
进一步地,步骤(8)中的模具为模具-钢板。
进一步地,步骤(9)中,温度为140℃,压力为3.0Mpa。
进一步地,步骤(5)中,若S/G偏长,加入0.1-0.2份催化剂用于加快反应;若S/G偏短,则按照步骤(1)-(4)另外配置S/G长的胶水,在配置过程中,邻甲酚醛环氧树脂添加分量增加5%-10%。
本发明的有益效果为:
1.从邻甲酚醛环氧树脂的分子结构中可以看出,每一个苯环上连接有一个环氧基团,与软化点在70~80℃区间的双酚A型环氧树脂(环氧值为0.2eq/100g)相比,邻甲酚醛环氧树脂的环氧值高达0.5 eq/100g以上,树脂固化时能够提供2.5倍的交联点,极易形成高交联密度的三维结构,加之固化物富含酚醛骨架,表现出优异的热稳定性、机械强度、电气绝缘性能、耐水性、耐化学药品性的较高的玻璃化温度(tg)。
2.该树脂软化点变化时,环氧值基本上无变化,而且熔融粘度相当低,赋予了树脂优异的工艺稳定性及加工工艺性。
3.通过加入端氨基液体橡胶、端羟基聚氨酯预聚体、封闭异氰酸酯及聚氨酯合成弹性体,可以解决环氧树脂固化后性脆,达到增韧环氧树脂的作用。

(6)将玻璃纤维布放入浸满胶水的含浸槽,胶水通过管路泵进入到含浸槽中,然后把浸透胶水的玻璃布放入烘箱中,烘干后得到半固化片;
(7)将半固化片按照计划要求的厚度,搭配不同的半固化片张数,堆叠好后送入组合室;
(8)将步骤(7)堆叠的半固化片覆上单面或者双面的铜箔,通过模具组合,组合好后送入热压机;
(9)利用高温使半固化片中树脂熔融,并于高压下将汽泡赶出,使树脂逐步硬化并与铜箔粘结;
(10)将压合好的基板裁掉边料,然后通过外观、厚度等检验后出货。
