1. Unsaturated polyester resin (UPR)
不飽和聚酯樹(shù)脂(UPR)是我國(guó)順酐更主要的消費(fèi)領(lǐng)城。不飽和聚酯樹(shù)脂是熱圓型樹(shù)脂的主要品種之一,由于其優(yōu)良的機(jī)械性能、電性能和耐化學(xué)腐蝕性能，且加工工藝簡(jiǎn)更,因此應(yīng)用廣泛。目前可以400余個(gè)牌號(hào)的UPR,主要品種包括鄰萃型、間苯型、對(duì)萃型、雙酚A型等,按用途和功能分類(lèi)包括通用樹(shù)脂、耐化學(xué)品樹(shù)脂、阻燃樹(shù)脂、澆注樹(shù)脂柔性樹(shù)脂、人造大理石,BMC與DMC樹(shù)脂、裝飾類(lèi)樹(shù)脂和特種樹(shù)脂等。的UPR市場(chǎng)中,增強(qiáng)類(lèi)(玻璃鋼用)樹(shù)脂比例只占40%,而用于非增強(qiáng)類(lèi)樹(shù)脂的比例高達(dá)60%,在非增強(qiáng)類(lèi)樹(shù)脂中工藝樹(shù)脂占34%，紐扣樹(shù)脂占24%,人造大理石占19%。
Unsaturated polyester resin (UPR) is the main consumption area of maleic anhydride in China. Unsaturated polyester resin is one of the main varieties of hot round resin. Because of its excellent mechanical properties, electrical properties, chemical corrosion resistance, and simple processing technology, it is widely used. At present, China can produce more than 400 brands of UPR, the main varieties include ortho extraction type, meta benzene type, para extraction type, bisphenol A type, etc. According to the use and function classification, it includes general resin, chemical resistant resin, flame retardant resin, cast resin flexible resin, artificial marble, BMC and DMC resin, decorative resin and special resin. In China's UPR market, the proportion of reinforced resin (used for glass fiber reinforced plastics) accounts for only 40%, while the proportion of non reinforced resin is up to 60%. Among non reinforced resin, process resin accounts for 34%, button resin accounts for 24%, and artificial marble accounts for 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(jī)和精細(xì)化工產(chǎn)品，在國(guó)內(nèi)較為緊俏,有著廣闊的應(yīng)用前更。順酐在加氫類(lèi)產(chǎn)品(包括BDO、THF和CBL等)中的應(yīng)用，特別是在新型熱塑性工程塑料聚對(duì)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(yīng)用，是過(guò)去10年間乃今后較長(zhǎng)一段時(shí)間內(nèi)能夠大幅拉動(dòng)全世界順酐產(chǎn)品迅速增長(zhǎng)的主要囚來(lái)。目前,這些產(chǎn)品在國(guó)內(nèi)的裝置規(guī)模較小,技術(shù)比較落后,每年都需從國(guó)外大量進(jìn)口來(lái)滿足國(guó)內(nèi)市場(chǎng)需求。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(jìn)一一步制備附加值更高的精細(xì)化學(xué)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(rèn)為是目前世界上1,4-丁二醇非常經(jīng)濟(jì)和有前途的工藝路線。
Maleic anhydride esterification and hydrogenation can produce 1,4-butanediol (BDO), tetrahydrofuran (THF) and other products. These organic and fine chemical products are relatively popular in China and have broad applications. The application of maleic anhydride in hydrogenation products (including BDO, THF, CBL, etc.), especially in the application of new thermoplastic engineering plastics PBT and PTMEC as the raw material of spandex, is the main culprit that can significantly drive the rapid growth of maleic anhydride products worldwide in the past 10 years and for a long time to come. At present, the domestic production facilities of these products are small and the technology is relatively backward, so they need to be imported from abroad in large quantities every year to meet the domestic market demand. Especially 1,4-butanediol, except for production γ- In addition to butyrolex and tetrahydrofuran, fine chemicals with higher added value, such as N-methylpyrrolidone and polytetramethylene glycol ether, can be further prepared step by step. Among them, maleic anhydride esterification hydrogenation is considered as a very economic 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(yīng)用主要是醇酸樹(shù)脂涂料和氨基樹(shù)脂涂料。醇酸樹(shù)脂涂料是18大類(lèi)除料中消費(fèi)量非常大的一類(lèi),產(chǎn)量和消費(fèi)量約占徐料總量的三分之一。醇酸樹(shù)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(jī)械和汽車(chē)涂裝、家俱以及防腐涂裝；氨基樹(shù)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。2003年全國(guó)醇酸樹(shù)脂徐料和氨基樹(shù)脂涂料的產(chǎn)量估計(jì)為75萬(wàn)噸，消耗順酐約1.14萬(wàn)噸。2005年我國(guó)對(duì)涂料的需求量達(dá)到約250.0萬(wàn)噸,其中醇酸樹(shù)脂和氨基樹(shù)脂涂料的需求量達(dá)到約87.5萬(wàn)噸，相應(yīng)對(duì)順酐的需求量達(dá)到約1.5萬(wàn)噸。
Maleic anhydride is mainly used in alkyd resin coatings and amino resin coatings. Alkyd resin coating is one of the 18 major categories of materials, and its consumption is very large. Its output and consumption account for about one third of the total amount of Xuzhou materials. Alkyd resin has good adhesion, glossiness and corrosion resistance, and is widely used in architectural coating, mechanical and automotive coating, furniture and anti-corrosion coating; Amino resin coatings also have good hardness, luster, light and color retention properties, and are widely used for decorative coating of light industrial household appliances. In 2003, the national production of alkyd resin and amino resin coatings was estimated to be 750,000 tons, and the consumption of maleic anhydride was about 11,400 tons. In 2005, China's demand for coatings reached about 2.5 million tons, including 875000 tons for alkyd resin and amino resin coatings, and 15000 tons for maleic anhydride.
