  生产醇酸树脂涂料Production of alkyd paint
  由间苯二甲酸和多元醇(乙二醇、丙三醇、季戊四醇)经缩聚制成的高固态、水基型或粉末型高分子聚酯类涂料与三聚氰酰胺/甲醛树脂或异氰酸酯交联制作高性能涂料,具有较好的水稳定性、耐化学性、户外耐候性和粘附性,干燥快、硬度高、光泽好、寿命长,适用建筑、家具、汽车等工业上油漆或烘漆。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.醇酸树脂除用作涂料外,还可制成醇酸树脂模塑塑料。在表面涂料中,间苯二甲酸型树脂的优点超过邻苯二酸酐型树脂,具有较好的水溶性,耐污染性和更好的耐候性。在干空气喷涂时,具有较快的干燥特性,特别是对高固态涂料特性的改进。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.间苯二甲酸聚酯涂料在工业上可应用于线圈、设备、汽车和许多其他设备的烘干喷涂。高固态、低溶剂的涂料还可用于办公家具、设备、工具及建筑物的喷涂。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.
  与苯酐类醇酸树脂相比较,间苯二甲酸醇酸树脂更易催干,由于催干性能好,可用来制造高固含量树脂和水基涂料,以减少对环境的污染。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%间苯二甲酸的醇酸树脂可制成高固含量达84%的涂料,可满足环保的要求;含量为29%左右的间苯二甲酸醇酸树脂可形成无溶剂水基涂料,与丙烯酸水基涂料相比,虽然其固化时间长,但光泽度好,具有较优良的耐冷冻性能,在严重潮湿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.
  间苯二甲酸还可用来生产紫外光固化涂料,这种涂料价格相对其他紫外光固化涂料来说价格较低,既有一定的刚性又有较好的柔韧性,可应用于家具、塑料制品和金属制件等方面。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.
  生产间苯二甲酸烯丙酯Between the production of acid allyl
  由间苯二甲酸为原料制备的间苯二甲酸烯丙酯主要有两个方面的用途。Prepared from isophthalic acid as a raw material of allyl isophthalate has two main purposes.一是直接聚合得到聚间苯二甲酸烯丙酯(DAIP)树脂,这种树脂加上增强材料和助剂造粒得到的DAIP热固性塑料,可以在200℃温度下使用,绝缘等级为H级。由于其电性能和机械性能比其他热固性树脂好,制品尺寸稳定,吸湿性小,广泛应用于制造精密、复杂耐高温绝缘的零部件和浸渍层压材料等。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.二是间苯二甲酸烯丙酯在不饱和树脂中代替苯乙烯做交联剂,加入量在30%左右。此类树脂优点是储存期长,尺寸稳定,耐水耐热。目前我国有上海曙光化工厂、上海天山塑料厂以及天津合成材料厂等厂家生产。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.
