順酐的主要用途及國內市場現狀

順酐主要應用于玻璃鋼行業的原料不飽和聚酯樹脂(UPR);加氫類產品中的1,4-丁二醇(BDO)、四氫呋喃(THF)和γ-丁內酯(GBL);也應用于涂料、潤滑油添加劑、農藥、酒石酸、琥珀酸及酐、四氫苯酐、改性松香等方面。
Maleic anhydride is mainly used as raw material of glass fiber reinforced plastics industry, unsaturated polyester resin (UPR); 1,4-butanediol (BDO), tetrahydrofuran (THF) and hydrogen peroxide in hydrogenation products γ- Butyrolactone (GBL); It is also used in coatings, lubricant additives, pesticides, tartaric acid, succinic acid and anhydride, tetrahydrophthalic anhydride, modified rosin, etc.
不飽和聚酯樹脂(UPR):是熱固型樹脂的主要品種之一,由于其優良的機械性能、電性能和耐化學腐蝕性能,且加工工藝簡便,因此應用廣泛。目前中國可以經營400余個牌號的UPR,主要品種包括鄰苯型、間苯型、對苯型、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。中國的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%。
Unsaturated polyester resin (UPR): is one of the main varieties of thermosetting resin, because of its excellent mechanical properties, electrical properties and chemical corrosion resistance, and simple processing technology, so it is widely used. At present, China can operate more than 400 brands of UPR, the main varieties include o-benzene, m-benzene, p-benzene, bisphenol A, etc., according to the use and function classification, including general resin, chemical resistant resin, flame retardant resin, pouring resin, flexible resin, artificial marble, BMC and DMC resin, decorative resin and special resin, etc. In China's UPR market, the proportion of reinforced (FRP) resin only accounts for 40%, while the proportion of non reinforced resin is as high as 60%. Among the non reinforced resins, process resin accounts for 34%, button resin 24%, and artificial marble 19%.
UPR行業一直都是順酐主要的消費領域,通常占順酐總消費量的40%~50%,而中國由于順酐下游產品用途相對較少,其應用在UPR行業的比例更是高達70%以上。
UPR industry has always been the main consumption field of maleic anhydride, usually accounting for 40% ~ 50% of the total consumption of maleic anhydride. However, due to the relatively small use of downstream products of maleic anhydride in China, the proportion of its application in UPR industry is as high as 70%.
加氫類產品:順酐在加氫類產品(包括BDO、THF和GBL等)中的應用,特別是在新型熱塑性工程塑料聚對苯二甲酸丁二醇酯(PBT)和作為氨綸原料的聚四亞甲基醚二醇(PTMEG)中的應用,是過去10年間乃至今后較長一段時間內,能夠大幅拉動全世界順酐產品迅速增長的主要因素。
Hydrogenation products: the application of maleic anhydride in hydrogenation products (including BDO, THF and GBL, etc.), especially in new thermoplastic engineering plastics polybutylene terephthalate (PBT) and polytetramethylene ether glycol (PTMEG) as raw material of spandex, is the focus in the past 10 years and even for a long time in the future, The main factors that can greatly promote the rapid growth of maleic anhydride products in the world.
涂料: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大類涂料中消費量大的一類,產量和消費量約占涂料總量的三分之一。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品的裝飾涂裝。
Coatings: maleic anhydride is mainly used in alkyd resin coatings and amino resin coatings. Alkyd resin coatings is one of the 18 major categories of coatings with large consumption. The output and consumption of alkyd resin coatings account for about one third of the total coatings. Alkyd resin has good adhesion, gloss and corrosion resistance, which is widely used in architectural coating, mechanical and automotive coating, furniture and anti-corrosion coating; Amino resin coating also has good hardness, luster and light and color retention performance, which is widely used in decorative coating of light industrial household appliances.
