    • A method for curing aminoplasts, during which layers having layer thicknesses of up to 300 um or filaments and fiber fibrids having a diameter of up to 300 um, which consist of: i) 95 to 99.95% by mass of solvent-free meltable aminoplast polycondensates with molar masses ranging from 1000 to 300000; j) 5 to 0.05% by mass of curing agents, which can be activated by actinic light and which are comprised of acidifiers of the blocked sulfonic acid and/or halogen-substituted triazine derivative and/or onium salt type, and optionally; k) 1 to 20% by mass, with regard to the meltable aminoplast polycondensates, of unmodified and/or modified maleic anhydride copolymers, and/or; i) 0.1 to 5% by mass, with regard to the meltable aminoplast polycondensates, of nanoparticles. The aminoplasts are cured by irradiating them with actinic light at a temperature between the melting point of the aminoplast polycondensate and the thermoinduced decomposition temperature of the light-activatable curing agents. This method enables the production of, preferably, textile fabrics or coatings.
    • 一种用于固化氨基塑料的方法,其中具有高达300μm的层厚度或直径高达300μm的长丝和纤维纤维素,其由以下组成:i)95至99.95质量%的无溶剂的可熔化氨基塑料缩聚物 摩尔质量范围为1000〜300000; j)5〜0.05质量%的固化剂,其可以通过光化剂活化,并且其由阻断的磺酸和/或卤素取代的三嗪衍生物和/或鎓盐型的酸化剂和任选的; k)1〜20质量%,相对于可熔融的氨基塑料缩聚物,未改性和/或改性的马来酸酐共聚物,和/或; i)相对于可熔化氨基塑料缩聚物,为0.1〜5质量%的纳米粒子。 通过在氨基塑料缩聚物的熔点和可光活化的固化剂的热分解温度之间的温度下用光化光照射氨基塑料来固化。 该方法能够生产优选的织物或涂层。

    • The invention relates to a flame-retardant mixture for lignocellulose composites having from 60 to 90% by mass of particulate or fibrous lignocellulose materials and from 40 to 10% by mass of a flame retardant concentrate immobilized on or in the particulate or fibrous lignocellulose materials as carriers. The flame retardants are boric acids or the salts thereof. Also, melamine resins and optionally synergistic agents and further additives may be present. The preparation of the flame-retardant mixture can be effected by a liquid impregnation process, a melt impregnation process and a liquid impregnation/solids mixing process. In the form of flame-retardant semifinished products and molding materials, the lignocellulose composites have high resistance to insect infestation, fungal infestation and mold infestation and high resistance to washing out of the flame-retardant mixture and are preferably suitable for applications in outdoor use in the building and leisure sector.
    • 本发明涉及一种用于木质素纤维素复合材料的阻燃混合物,其具有60至90质量%的颗粒或纤维状木质纤维素材料和40至10质量%固定在颗粒状或纤维状木质纤维素材料上或其中的阻燃剂浓缩物, 承运人 阻燃剂是硼酸或其盐。 此外,可以存在三聚氰胺树脂和任选的增效剂和其它添加剂。 阻燃混合物的制备可以通过液体浸渍法,熔融浸渍法和液体浸渍/固体混合法进行。 以阻燃半成品和成型材料的形式,木质纤维素复合材料对昆虫侵染,真菌侵染和霉菌侵染具有很高的抗性,并且耐高温阻燃混合物的洗涤,并且优选适用于户外使用 建筑和休闲部门。
