關于間苯二甲酸-5-磺酸鈉的用途(二)
生產醇酸樹脂涂料Production of alkyd paint
由間苯二甲酸和多元醇(乙二醇、丙三醇、季戊四醇)經縮聚制成的高固態(tài)、水基型或粉末型高分子聚酯類涂料與三聚氰酰胺/甲醛樹脂或異氰酸酯交聯制作高性能涂料,具有較好的水穩(wěn)定性、耐化學性、戶外耐候性和粘附性,干燥快、硬度高、光澤好、壽命長,適用建筑、家具、汽車等工業(yè)上油漆或烘漆。Isophthalic acid and a polyhydric alcohol (ethylene glycol, glycerol, pentaerythritol) formed by the condensation of high solids, water-based or powder coatings and high-molecular polyester-based amide melamine / formaldehyde resin or isocyanate cross Joint production of high performance coatings, has good water stability, chemical resistance, outdoor durability and adhesion, fast drying, high hardness, good gloss, a long life, suitable for construction, furniture, automotive and other industrial paint or bake paint.醇酸樹脂除用作涂料外,還可制成醇酸樹脂模塑塑料。在表面涂料中,間苯二甲酸型樹脂的優(yōu)點超過鄰苯二酸酐型樹脂,具有較好的水溶性,耐污染性和更好的耐候性。在干空氣噴涂時,具有較快的干燥特性,特別是對高固態(tài)涂料特性的改進。In addition to use as alkyd paint, it can also be made alkyd resin molded plastic. In surface coatings, the advantages of the isophthalic acid type resin exceeds phthalic anhydride resin, has good water solubility, stain resistance and better weather resistance. In dry air for spraying, with a fast drying characteristics, especially high solids coating properties improvements.間苯二甲酸聚酯涂料在工業(yè)上可應用于線圈、設備、汽車和許多其他設備的烘干噴涂。高固態(tài)、低溶劑的涂料還可用于辦公家具、設備、工具及建筑物的噴涂。Isophthalic polyester coating can be applied on an industrial spray drying the coil, equipment, automobiles and many other devices. High solids, low-solvent coatings can also be used for spraying office furniture, equipment, tools and buildings.
與苯酐類醇酸樹脂相比較,間苯二甲酸醇酸樹脂更易催干,由于催干性能好,可用來制造高固含量樹脂和水基涂料,以減少對環(huán)境的污染。Compared with phthalic anhydride Alkyd resins, alkyd resins isophthalic more driers, driers due to good performance, can be used to manufacture high solid content of the resin and water-based paints to reduce pollution of the environment.含有20%間苯二甲酸的醇酸樹脂可制成高固含量達84%的涂料,可滿足環(huán)保的要求;含量為29%左右的間苯二甲酸醇酸樹脂可形成無溶劑水基涂料,與丙烯酸水基涂料相比,雖然其固化時間長,但光澤度好,具有較優(yōu)良的耐冷凍性能,在嚴重潮濕下比丙烯酸涂料的起泡性小。20% isophthalic alkyd resin containing high solid content can be made up to 84% of the paint, which can meet environmental requirements; content of about 29% of isophthalic alkyd resin to form a water-based solvent-free coatings, compared with acrylic water-based paints, although long curing time, but the gloss is good, with excellent resistance to freezing than the performance under severe moisture smaller than acrylic paint foaming.
間苯二甲酸還可用來生產紫外光固化涂料,這種涂料價格相對其他紫外光固化涂料來說價格較低,既有一定的剛性又有較好的柔韌性,可應用于家具、塑料制品和金屬制件等方面。Isophthalic acid can also be used to produce UV-curable coatings, this coating price relative to other UV-curable coatings for lower prices, both have a certain rigidity better flexibility, can be applied to furniture, plastics and metal parts and so on.
生產間苯二甲酸烯丙酯Between the production of acid allyl
由間苯二甲酸為原料制備的間苯二甲酸烯丙酯主要有兩個方面的用途。Prepared from isophthalic acid as a raw material of allyl isophthalate has two main purposes.一是直接聚合得到聚間苯二甲酸烯丙酯(DAIP)樹脂,這種樹脂加上增強材料和助劑造粒得到的DAIP熱固性塑料,可以在200℃溫度下使用,絕緣等級為H級。由于其電性能和機械性能比其他熱固性樹脂好,制品尺寸穩(wěn)定,吸濕性小,廣泛應用于制造精密、復雜耐高溫絕緣的零部件和浸漬層壓材料等。First, the direct polymerization of poly allyl phthalate (DAIP) resin which together with reinforcements and additives resulting DAIP thermosetting plastics granulation can be used at a temperature of 200 ℃, insulation class H. Because of its good electrical and mechanical properties compared to other thermosetting resins, product size and stability, low moisture absorption, is widely used in the manufacture of sophisticated, complex parts and high temperature insulation materials impregnated laminate.二是間苯二甲酸烯丙酯在不飽和樹脂中代替苯乙烯做交聯劑,加入量在30%左右。此類樹脂優(yōu)點是儲存期長,尺寸穩(wěn)定,耐水耐熱。目前我國有上海曙光化工廠、上海天山塑料廠以及天津合成材料廠等廠家生產。Second, instead of styrene allyl isophthalic unsaturated resin crosslinking agents do, the amount of about 30%. Such resins advantage of long storage period, dimensionally stable, water-resistant. Currently, there are Shanghai Shuguang Chemical Factory, Shanghai Tianshan plastics factory and Tianjin factory and other synthetic materials manufacturers.
