polyether resin 中文意思是什麼
polyether resin
解釋
聚醚樹脂-
The first group is polyurethane prepolumer which is made from polyether resin and diisocyanate etc after polymerization ; the second group is made by mixing up cross linker, accelerator, softener, densifier, mold preventive and stuffing etc
甲組分別是以聚醚樹脂和二異氰酸脂等為原料，經聚合反應製成的含端異氰酸脂基的聚氨基甲酸脂預聚物；乙組分別由交聯劑、促進劑、增韌劑、增黏劑、防霉劑和填充劑等混合加工而成。 -
The influence of catalyst on the copolymerization of epoxy and cyanate was investigated, and the mechanism of their copolymerization was discussed. the catalyst can obviously accelerate the curing of the resin to decrease the curing temperature. the three kinds of reactions ( cyclotrimerization, co - reaction and polyetherification ) in their copolymerization are not simultneous and independent to each other. in the lack of cyanate functional group, the main structures are oxazoine and polyether structure in the cured resin, and the triazine ring structure is of miner importance
研究了催化劑對環氧樹脂與氰酸酯樹脂的共聚固化反應行為的影響，並初步探索氰酸酯/環氧固化的反應歷程.研究表明，催化劑能明顯地促進其固化反應，降低固化溫度，縮短固化時間；氰酸酯與環氧共聚反應歷程是首先氰酸酯三聚反應生成三嗪環結構，然後三嗪環開環與環氧共聚反應，最後是未能參與共聚反應的環氧官能團在唑啉結構和三嗪環的催化下發生聚醚化反應；在氰酸酯官能團欠量的條件下，固化樹脂中主要是唑啉和聚醚結構，而三嗪環結構的含量很少 -
In comparison with unmodified epoxy resin, the impart strength of modified epoxy resin by fh type polyether polyols has increased by 124 %, the fracture toughness ratio by 89 %, and the fracture energy ratio by 260 %
與未改性的環氧樹脂相比，用fh聚醚多元醇改性環氧樹脂的沖擊強度增加124 % ，斷裂韌性比增加89 % ，斷裂能比增加260 % 。
