Description

無鹵樹脂組合物以及由其製備的膠膜、覆蓋膜和覆銅板Halogen-free resin composition and adhesive film, cover film and copper-clad board prepared therefrom

本發明涉及撓性印刷電路板技術領域,尤其涉及一種無鹵樹脂組合物以及由其製備的膠膜、覆蓋膜和覆銅板。The invention relates to the technical field of flexible printed circuit boards, in particular to a halogen-free resin composition, and an adhesive film, a cover film and a copper-clad board prepared therefrom.

膠膜、覆蓋膜和覆銅板是製作撓性印刷電路板的基礎材料,隨著電子資訊技術的發展,市場對其性能的要求越來越高,尤其是耐熱性能、耐老化性能、阻燃性能和黏接性能。較常見的膠膜、覆蓋膜和三層法撓性覆銅板所用膠黏劑以環氧樹脂/丁腈橡膠為主要成分並且搭配固化劑、阻燃劑及其他助劑組分,其剝離強度一般較低,耐熱性和耐老化性能較差。為改善耐熱性,中國專利CN101323773B和中國專利申請公開號CN102199413A以雙馬來醯亞胺預聚物改性環氧樹脂/丁腈橡膠體系;中國專利申請公開號CN104531030A不使用丁腈橡膠,而是以酚醛樹脂改性柔性環氧體系;中國專利CN103834343B以柔性固化劑固化多官能環氧樹脂。上述方法均能夠提高覆銅板製品的耐熱性,但製品的柔韌性能會有較大損失。Adhesive film, cover film and copper-clad board are the basic materials for making flexible printed circuit boards. With the development of electronic information technology, the market has increasingly demanded performance, especially heat resistance, aging resistance, and flame retardancy. And adhesive properties. More common adhesive films, cover films and three-layer flexible copper-clad laminates use epoxy / nitrile rubber as the main component and are combined with curing agents, flame retardants and other auxiliary components. Lower, poor heat resistance and aging resistance. In order to improve heat resistance, Chinese patent CN101323773B and Chinese patent application publication number CN102199413A use bismaleimide imide prepolymer to modify epoxy resin / nitrile rubber system; Chinese patent application publication number CN104531030A does not use nitrile rubber, but instead Flexible epoxy system is modified with phenolic resin; Chinese patent CN103834343B is used to cure multifunctional epoxy resin with flexible curing agent. The above methods can improve the heat resistance of copper clad laminate products, but the flexibility of the products will be greatly lost.

日本專利JP2009-96940A、中國專利申請公開號CN105482442A等採用聚胺酯樹脂為主體樹脂,搭配環氧樹脂、酚醛樹脂等其他樹脂及阻燃劑,製備了覆蓋膜及覆銅板,產品的柔韌性和剝離強度均較佳。中國專利CN102822304B以聚胺酯為主體樹脂,搭配聚酯樹脂、環氧樹脂,製得的膠黏劑耐濕熱性能、低溫彎折性能和流動性較好。但聚胺酯受胺基甲酸酯結構的影響,耐熱性能和耐老化性能較差,浸錫後的剝離強度較低。Japanese patent JP2009-96940A, Chinese Patent Application Publication No. CN105482442A, etc. use polyurethane resin as the main resin, with epoxy resin, phenolic resin and other resins and flame retardants to prepare cover films and copper clad laminates. The product's flexibility and peel strength Both are better. Chinese patent CN102822304B uses polyurethane as the main resin, with polyester resin and epoxy resin. The adhesive produced has good moisture resistance, low temperature bending performance and fluidity. However, polyurethane is affected by the urethane structure, and has poor heat resistance and aging resistance. The peel strength after immersion in tin is low.

因此,目前迫切期望開發出一種新的樹脂組合物,通過採用該樹脂組合物所製備的膠膜、覆蓋膜和覆銅板具有優異的柔韌性、耐熱性、耐老化性和剝離強度。Therefore, it is currently urgent to develop a new resin composition, and the adhesive film, cover film, and copper clad laminate prepared by using the resin composition have excellent flexibility, heat resistance, aging resistance, and peeling strength.

根據在以上測試方法部分中描述的測量方法,對在以上實施例1~8和比較例1~8中得到的覆蓋膜或覆銅板的各項性能(覆型性、極限耐浸焊溫度、剝離強度、阻燃性和耐浸焊性)進行了測試。其中,關於撓性印刷電路板用覆蓋膜的測試結果顯示在以下表1~表2中;關於撓性印刷電路板用單面覆銅板的測試結果顯示在以下表3~表4中。According to the measurement methods described in the above test method section, the properties of the cover film or copper-clad board obtained in the above Examples 1 to 8 and Comparative Examples 1 to 8 (coverability, extreme dip soldering temperature, peel strength) , Flame retardancy and solder resistance) were tested. The test results of the cover film for flexible printed circuit boards are shown in Tables 1 to 2 below, and the test results of the single-sided copper-clad boards for flexible printed circuit boards are shown in Tables 3 to 4 below.

〔表1〕實施例1~4中得到的撓性印刷電路板用覆蓋膜的性能測試結果 [Table 1] Performance test results of the cover films for flexible printed circuit boards obtained in Examples 1 to 4

〔表2〕比較例1~4中得到的撓性印刷電路板用覆蓋膜的性能測試結果 [Table 2] Performance test results of the cover films for flexible printed circuit boards obtained in Comparative Examples 1 to 4

由表1中的實施例1~4的測量結果可以看出,採用本發明無鹵樹脂組合物製備的覆蓋膜具有優異的耐熱性能,極限耐浸焊溫度超過360℃,288℃浸錫20s剝離強度保持率大於85%;搭配含氮阻燃劑時,288℃浸錫60s剝離強度保持率仍然大於85%,部分製品的剝離強度甚至有所提高,170℃老化10h後的剝離強度保持率均大於80%。另外,覆蓋膜的溢膠量適中,覆型性合格,覆合銅箔後燃燒性達到V0級。From the measurement results of Examples 1 to 4 in Table 1, it can be seen that the cover film prepared by using the halogen-free resin composition of the present invention has excellent heat resistance performance, the ultimate resistance to dip soldering temperature exceeds 360 ° C, and the peel strength of 288 ° C immersion tin for 20 seconds The retention rate is greater than 85%; when the nitrogen-containing flame retardant is used, the peel strength retention rate of immersion tin at 288 ℃ for 60s is still greater than 85%, and the peel strength of some products is even improved. 80%. In addition, the overflow of the cover film is moderate, and the moldability is acceptable. The flammability after the copper foil is laminated reaches V0 level.

反觀表2中的比較例1~4的測試結果,可以看出,比較例1中以聚胺酯膠黏劑製備的覆蓋膜極限耐浸焊溫度明顯低於本發明樹脂組合物製備的覆蓋膜,且浸錫後剝離強度突降。比較例2中以異氰酸酯代替含氮環氧化合物,促進樹脂組合物固化,製得的覆蓋膜,雖然360℃浸錫20s無起泡現象,但288℃浸錫後的剝離強度會急劇下降,說明其綜合耐熱性能不佳。如關於比較例3的結果可知,若無含氮環氧化合物作為固化促進劑,膠黏劑達到半固化狀態的時間較長,288℃浸錫後剝離強度急劇下降。另外,比較例4採用的樹脂種類與本發明相同,但組分的比例不同,可以發現其耐熱性能不足,覆型性差。因此,本發明的樹脂組合物不僅要求含羧基聚酯樹脂、多官能環氧樹脂和含氮環氧化合物的搭配,還要求其各組分的配比,才能製得具有優異性能的覆蓋膜。Looking back at the test results of Comparative Examples 1 to 4 in Table 2, it can be seen that the limit dip soldering temperature of the cover film prepared by using the polyurethane adhesive in Comparative Example 1 is significantly lower than that of the cover film prepared by the resin composition of the present invention. After the tin peeling strength drops suddenly. In Comparative Example 2, the isocyanate was used instead of the nitrogen-containing epoxy compound to promote the curing of the resin composition. Although the coating film obtained had no foaming after being immersed in tin at 360 ° C for 20s, the peel strength after immersion in tin at 288 ° C would decrease sharply. Its comprehensive heat resistance is poor. As can be seen from the results of Comparative Example 3, if the nitrogen-containing epoxy compound is not used as a curing accelerator, it takes a long time for the adhesive to reach a semi-cured state, and the peel strength decreases sharply after dipping at 288 ° C. In addition, the resin used in Comparative Example 4 was the same as that of the present invention, but the proportions of the components were different, and it was found that the heat resistance was insufficient and the moldability was poor. Therefore, the resin composition of the present invention not only requires the combination of a carboxyl-containing polyester resin, a polyfunctional epoxy resin, and a nitrogen-containing epoxy compound, but also requires the proportion of each component thereof to obtain a cover film having excellent properties.

〔表4〕比較例5~8中得到的撓性印刷電路板用單面覆銅板的性能測試結果 [Table 4] Performance test results of single-sided copper-clad boards for flexible printed circuit boards obtained in Comparative Examples 5 to 8

由表3和表4可以看出,撓性印刷電路板用單面覆銅板的剝離強度、耐浸焊性能、耐老化性能與無鹵樹脂組合物配方的關係和覆蓋膜與無鹵樹脂組合物配方的關係類似,按照本發明所述方法實施的實施例中得到覆銅板的性能優異。As can be seen from Tables 3 and 4, the relationship between the peel strength, dip solder resistance, and aging resistance of the single-sided copper-clad laminate for flexible printed circuit boards and the formulation of the halogen-free resin composition, and the formulation of the cover film and the halogen-free resin composition The relationship is similar, and the performance of the copper clad laminates obtained in the embodiments implemented according to the method of the present invention is excellent.

綜上所述,本發明的無鹵樹脂組合物包含含羧基的聚酯樹脂、多官能環氧樹脂、含氮環氧化合物、阻燃劑和有機溶劑,其中含羧基聚酯樹脂可與多官能環氧樹脂反應,多官能環氧樹脂可以發生自聚反應,並且含氮環氧化合物可以促進上述反應的進行,促進形成互穿聚合物網絡結構,使得固化產物具有優異的耐熱性能、耐老化性能和黏結性能。In summary, the halogen-free resin composition of the present invention comprises a carboxyl-containing polyester resin, a polyfunctional epoxy resin, a nitrogen-containing epoxy compound, a flame retardant, and an organic solvent. Epoxy resin reaction, polyfunctional epoxy resin can undergo self-polymerization reaction, and nitrogen-containing epoxy compounds can promote the above reaction and promote the formation of interpenetrating polymer network structure, so that the cured product has excellent heat resistance and aging resistance And adhesive properties.

本發明樹脂組合物製作的覆蓋膜和覆銅板具有優異的耐熱性能、耐老化性能,較高的剝離強度,覆合銅箔後阻燃等級達到UL94-V0級,綜合性能優異。The cover film and the copper-clad board made of the resin composition of the present invention have excellent heat resistance, aging resistance, high peel strength, and the flame-retardant grade after the copper foil is laminated reaches UL94-V0 level, and the comprehensive performance is excellent.
