不飽和聚酯樹脂( UPR)是我國順酐更主要的消費領城。不飽和聚酯樹脂是熱圓型樹脂的主要品種之一,由于其優(yōu)良的機械性能、電性能和耐化學腐蝕性能，且加工工藝簡更,因此應用廣泛。目前可以400余個牌號的UPR,主要品種包括鄰萃型、間苯型、對萃型、雙酚A型等,按用途和功能分類包括通用樹脂、耐化學品樹脂、阻燃樹脂、澆注樹脂柔性樹脂、人造大理石,BMC與DMC樹脂、裝飾類樹脂和特種樹脂等。
Unsaturated polyester resin (UPR) is the main consumption leader of maleic anhydride in China. Unsaturated polyester resin is one of the main varieties of hot round resin. It is widely used because of its excellent mechanical properties, electrical properties, chemical corrosion resistance and simpler processing technology. At present, it can produce more than 400 brands of UPR, mainly including ortho extraction type, meta benzene type, para extraction type, bisphenol a type, etc. according to the purpose and function, it includes general resin, chemical resistant resin, flame retardant resin, casting resin, flexible resin, artificial marble, BMC and DMC resin, decorative resin and special resin.
的UPR市場中,增強類(玻璃鋼用)樹脂比例只占40% ,而用于非增強類樹脂的比例高達60% ,在非增強類樹脂中工藝樹脂占34%，紐扣樹脂占24% ,人造大理石占19%。
In the UPR market, the proportion of reinforced (FRP) resin accounts for only 40%, while the proportion of non reinforced resin is as high as 60%. In the non reinforced resin, process resin accounts for 34%, button resin 24% and artificial marble 19%.
2. BDO、THF等加氫產(chǎn)品
2. BDO, THF and other hydrogenation products
順酐酯化加氫可以1,4-丁二醇( BDO)、四氫呋喃(THF)等產(chǎn)品,這些有機和精細化工產(chǎn)品，在國內(nèi)較為緊俏,有著廣闊的應用前更。順酐在加氫類產(chǎn)品(包括BDO、THF和CBL等)中的應用，特別是在新型熱塑性工程塑料聚對萃二甲酸丁二醇面( PBT)和作為氨綸原料的聚四亞甲基醚二醇( PTMEC)中的應用，是過去10年間乃今后較長一段時間內(nèi)能夠大幅拉動全世界順酐產(chǎn)品迅速增長的主要囚來。目前,這些產(chǎn)品在國內(nèi)的裝置規(guī)模較小,技術比較落后, 每年都需從國外大量進口來滿足國內(nèi)市場需求。
Maleic anhydride esterification hydrogenation can produce 1,4-butanediol (BDO), tetrahydrofuran (THF) and other products. These organic and fine chemical products are in short supply in China and have broad application prospects. The application of maleic anhydride in hydrogenation products (including BDO, THF and CBL), especially in new thermoplastic engineering plastics polybutylene terephthalate (PBT) and polytetramethylene ether glycol (ptmec) as raw material of spandex, is the main factor that can significantly drive the rapid growth of maleic anhydride products all over the world in the past 10 years and even for a long time in the future. At present, the domestic production units of these products are small in scale and backward in technology. They need to be imported from abroad every year to meet the needs of the domestic market.
尤其是1 ,4-丁二醇,除用于γ-丁內(nèi)雷、四氫呋喃外,還可以進一一步制備附加值更高的精細化學品N-甲基吡咯炕酮和聚四亞甲基乙二醇醚等。其中順酐酯化加氫被認為是目前世界上1,4-丁二醇更經(jīng)濟和更有前途的工藝路線。
In particular, 1,4-butanediol is used for production γ- In addition to butamer and tetrahydrofuran, it can also further prepare fine chemicals with higher added value, such as N-methylpyrrolidone and polytetramethylene glycol ether. Among them, maleic anhydride esterification hydrogenation is considered to be the most economical and promising production process for the production of 1,4-butanediol in the world.
3. 涂料方面
3. Coating
順酐在涂料方面的應用主要是醇酸樹脂涂料和氨基樹脂涂料。醇酸樹脂涂料是18大類除料中消費量的一類,產(chǎn)量和消費量約占徐料總量的三分之一。醇酸樹脂具有良好的附著力、光澤度和抗腐蝕等性能,廣泛用于建筑涂裝、機械和汽車涂裝、家俱以及防腐涂裝；氨基樹脂涂料也有良好的硬度、光澤和保光保色性能，廣泛用于輕工家電產(chǎn)品的裝飾涂裝。
Maleic anhydride is mainly used in alkyd resin coatings and amino resin coatings. Alkyd resin coating is the largest consumption among the 18 categories of materials, and its output and consumption account for about one third of the total materials in Xu. Alkyd resin has good adhesion, gloss and corrosion resistance. It is widely used in architectural coating, mechanical and automotive coating, furniture and anti-corrosion coating; Amino resin coatings also have good hardness, gloss and color retention properties. They are widely used in decorative coating of light industrial household appliances.
2003 年全國醇酸樹脂徐料和氨基樹脂涂料的產(chǎn)量估計為75萬噸，消耗順酐約1.14萬噸。2005年我國對涂料的需求量達到約250. 0萬噸,其中醇酸樹脂和氨基樹脂涂料的需求量達到約87.5萬噸，相應對順酐的需求量達到約1.5萬噸。
In 2003, the output of alkyd resin and amino resin coatings in China was estimated to be 750000 tons, and the consumption of maleic anhydride was about 11400 tons. In 2005, the demand for coatings in China reached about 250 Million tons, including about 875000 tons of alkyd resin and amino resin coatings, and about 15000 tons of maleic anhydride.
