The invention relates to waterborne polyurethane polyamide resin emulsion for a metal surface coating and a preparation method of the emulsion. The emulsion is prepared from the following components in parts by weight: 70-85 parts of polyamide resin polyalcohol, 15-30 parts of polytetrahydrofuran, 5-25 parts of amino silicon oil, 65-85 parts of isophorone diisocyanate, 0.5 part of organic bismuth, 5-15 parts of 1,4-butanediol, 10-15 parts of dimethylolpropionic acid, 5-10 parts of diethylenetriamine and a proper amount of a solvent. The preparation method comprises the following steps: mixing polyamide resin polyalcohol, polytetrahydrofuran, amino silicon oil, isophorone diisocyanate and organic bismuth, heating for reaction, adding 1,4-butanediol and dimethylolpropionic acid for reaction, adding the solvent during the reaction to control the viscosity, cooling, emulsifying, and adding diethylenetriamine for continuous reaction. The emulsion can be applied to a metal surface, is equivalent to an overseas similar product in performance, is much cheaper than the overseas similar product sold in China, has relatively good market prospects, and can bring relatively good economic benefits to production enterprises.

The invention relates to the technical field of web pages of an internet technology, and particularly discloses a social network platform system and an interaction method. The social network platform system comprises an international language module, a global social networking service module, an electronic commerce module, a credit evaluation module, a record retention module, an information synchronization module, a help module and a positioning module. The international language module is used for automatically identifying the language of a client-side. The global social networking service module is used for the client-side to carry out social activities. The electronic commerce module is used for the client-side to carry out electronic commerce activities. The credit evaluation module is used for evaluating the credit standing of the client-side. The record retention module is used for recording and storing the operating information of the client-side. The information synchronization module is used for carrying out real-time and synchronous update on the operating information of the client-side. The help module is used for solving the help requests of the client-side. The positioning module is used for positioning the geographic position of the client-side through a GPS. The social network platform system combines the electronic commerce and a social network site, saves a great amount of time of a user, provides different business environment modes for different industries, is convenient for users with different languages to operate and use, reduces the operation cost of a developer, pays attention to user experience, and enlarges the rights of own choices of the user.
