環(huán)氧樹(shù)脂薄膜電容具有優(yōu)良的阻燃性,是在原始薄膜電容的基礎(chǔ)之上進(jìn)行了更高技術(shù)要求的升級(jí)。之所以采用環(huán)氧樹(shù)脂是因?yàn)榄h(huán)氧樹(shù)脂及其固化物是熱固性樹(shù)脂中綜合性能最好的。
Epoxy resin film capacitor has excellent flame retardancy, which is an upgrade of higher technical requirements based on the original film capacitor. The reason why epoxy resin is used is that epoxy resin and its cured products are the best comprehensive performance among thermosetting resins.
環(huán)氧樹(shù)脂是泛指分子中含有兩個(gè)或兩個(gè)以上環(huán)氧基團(tuán)的有機(jī)高分子化合物,活潑的環(huán)氧基團(tuán)可以位于分子鏈的末端、中間或成環(huán)狀結(jié)構(gòu)。環(huán)氧樹(shù)脂薄膜電容具備了環(huán)氧樹(shù)脂的所有優(yōu)點(diǎn)。
Epoxy resin is a kind of organic polymer with two or more epoxy groups in the molecule. The active epoxy group can be located at the end, middle or ring structure of the molecular chain. Epoxy resin film capacitor has all the advantages of epoxy resin.
1、它有優(yōu)良的物理機(jī)械性能、電絕緣性,固化收縮率小;
It has excellent physical and mechanical properties, electrical insulation and small curing shrinkage;
2、穩(wěn)定性好,固化后的環(huán)氧樹(shù)脂主鏈?zhǔn)敲焰I和苯環(huán),三維交聯(lián)結(jié)構(gòu)致密又封閉,因此它耐酸、耐堿及多種介質(zhì);
The cured epoxy resin has good stability. The main chain of cured epoxy resin is ether bond and benzene ring, and its three-dimensional cross-linking structure is dense and closed, so it is resistant to acid, alkali and various media;
3、粘結(jié)強(qiáng)度高,尤其是環(huán)氧基團(tuán)能與固化劑作用交聯(lián)生成大分子,具有很強(qiáng)的內(nèi)聚力;
The adhesive strength is high, especially the epoxy group can react with curing agent to form macromolecules and has strong cohesive force;
4、原料容易取得,制造技術(shù)并不復(fù)雜,設(shè)備也比較簡(jiǎn)單且工藝性好;
Raw materials are easy to obtain, the manufacturing technology is not complex, the equipment is relatively simple and the process is good;
5、使用方便,能作為涂料,電氣絕緣材料,膠粘劑澆注料,灌封料,包封料及玻璃鋼等,用途十分廣泛,在國(guó)民經(jīng)濟(jì)各領(lǐng)域中起著不可缺少的重要作用。
Easy to use, it can be used as coating, electrical insulation material, adhesive, castable, potting material, wrapping material and glass fiber reinforced plastic, etc. it is widely used and plays an indispensable and important role in various fields of national economy.
環(huán)氧樹(shù)脂薄膜電容在電網(wǎng)建設(shè)、電氣化鐵路建設(shè)、節(jié)能照明、混合動(dòng)力汽車(chē)等市場(chǎng)需求呈現(xiàn)了快速增長(zhǎng)的趨勢(shì)。
The demand of epoxy resin film capacitor in power grid construction, electrified railway construction, energy-saving lighting, hybrid electric vehicle and other market demand shows a rapid growth trend.
