          最近,我司的第一项国际发明专利正式授权。

            Recently, Our company’s first international invention patent had been authorized.

        专利名称:改性1,6-己二异氰酸酯缩二脲固化剂及其制备方法

        Name: Introduction and preparation method of modified 1,6-hexamethylene diisocyanate biuret

        国家发明专利授权号:ZL 201110028404.8

        National invention patent No.:ZL 201110028404.8

        德国发明专利授权号:Nr.11 2011 101 335.3   

        Deutsch invention patent No.:Nr.11 2011 101 335.3

        高性能聚氨酯涂料和胶粘剂使用的脂肪族不变黄型二异氰酸酯固化剂,主要是HDI缩二脲和HDI三聚体,用于高档轿车涂料、外墙涂料、舰船涂料和桥梁涂料,以及耐高温蒸煮的食品包装复合膜,其特点是制成的产品光、热稳定性好,在户外紫外线照射下不会发生泛黄现象,在高温蒸煮条件下不会发生芳香族异氰酸酯变成致癌芳香胺的化学反应。目前,国际上这两种产品的加工工艺复杂、生产效率低,而且设备昂贵,而我司的专利却有效地克服这一问题。

        HDI biuret and HDI tripolymer,a kind of Non-yellowing aliphatics diisocyanate hardener mix used with high performance polyurethane coating and adhesive,are suitable for curing the coating used in high class car,outer wall,ships and bridge and the adhesive used for thermostable laminated sheets od food package.

        Characteristic of products:

            1.Good light and heat stability.Won't become yellow in ultraviolet irradiation outdoors.

        2.Won't occur chemical reaction,which aromatic isocyanate changes into carcinogenic aromatic amine,in thermophilic digestion.

        Presently,the international preparation methods of HDI biuret and HDI tripolymer is complex,Inefficient,high-cost.The patent can overcome the problem effectively.

        本专利重点突破HDI缩二脲生产转化率低的制造技术,目前国际上生产HDI缩二脲产率在30%~40%之间,本专利的创新思路,将产品转化率提高到80%~95%,超过国际方法的一倍以上,能耗低,设备利用率高。

        The emphasis of this patent is to overcome the problem of low Conversion rate.Now,the Conversion rate of HDI biuret worldwide is 30~40%,but the Conversion rate of our patent had been improved to 80%~95% with low energy consumption and high device availability.

        投入生产并销售多年,得到用户一致好评:不仅应用工艺性良好,产品性能达到进口HDI缩二脲固化剂的相当水平,而且价格比进口产品便宜,深受用户欢迎。

        Put on stream and sold for many years,It gets high opinion from consumers:Not only it has good product performance,but also it is more preferential than import HDI biuret.

        本发明专利以不同于国际上传统的工艺方法制造出HDI缩二脲固化剂,是湖北省重点新产品项目,它的开发成功,打破了我国高性能涂料和耐高温蒸煮胶粘剂使用的HDI缩二脲固化剂完全依赖进口的局面,提高了我国聚氨酯制造业的技术水平,具有重要的经济社会效益。

        This patent is totally different from traditional preparation methods,and one of key new products of Hubei province.It breaks the Predicament that HDI biuret total depended on import in China and improve the engineering level of polyurethane industry in China.It has important economic and social benefits.
