Description of the invention (1) The present invention is a novel preparation method of fatty acid gold salt, by which the preparation method can effectively reduce the residual fatty acid Content, and the fatty acid gold salt produced can be successfully applied to photodegradable plastics as a photosensitizer for the material. Fatty acid metal salts are used as photosensitizers in photodegradable plastics, which have been shown in many patents, such as US Patent 3840512, 3865767, 3882058, Ti, V, Cr, Mn, Fe, Co, Ni, Cu , Fatty acid metal salts made of other metals are used as photosensitizers. Among them, the photosensitizer used in US Patent 3865767 is Di-Soap, hard Y ferric stearate (H0-F <), where Y is a fatty acid with a sulfonic acid number of 6 ~ 25; After some metal ligands are replaced by fatty acids, they have good compatibility with plastics and are an excellent photosensitizer. The fatty acid gold salt synthesized by this patent process belongs to this type of compound. It is applied to photodegradable plastics and has a good effect of accelerating the decomposition of plastics. In addition to the above photosensitizer applications, fatty acid metal salts are also widely used. They can be used as drying hardeners for paints, inks and other materials, as slip agents for plastics and rubber, as hardening accelerators for unsaturated polyester, or as plastics. Stabilizers, etc. The existing synthesis methods of fatty acid metal salts can be roughly divided into the following three categories: the first type is the melting method, this method is to directly react with gold oxide or argon oxide to produce fatty acid metal salts after heating and melting the fatty acid, this method Although the production equipment is relatively simple, it has the following disadvantages: (a) high temperature reaction, about 150C ~ 200T :, it is easy to make the product darker; (b) the reaction is not (please read the back of the department and the precautions first # 锅 写 木Page) Binding < Order-Line < This paper size is used in China National Standard (CNS) T4 regulations (210X297; ¢) 205543 A6 B6 5. Description of invention (2) Printed by the Central Standards Bureau of the Ministry of Economic Affairs {please Read the precautions on the back before filling in this page). Thread · Easy to complete, the reactants are likely to remain in the final fatty acid metal salt; (C) The resulting product must be crushed and ground to increase the production process; (d) Metal Oxides are easy to mix with other metal ions. Generally speaking, the purity is lower, and higher purity products cannot be obtained. The second type is the double decomposition method. This method involves saponification of fatty acid and sodium hydroxide to produce fatty acid sodium, and then adding Jinzhan salt aqueous solution to produce fatty acid metal salt. The reaction temperature is low, about 60¾ ~ 901C The stearate produced by this method can improve most of the defects of the above melting method, and obtain products with good hue, high metal purity and fine powder. It is the most commonly used commercial production method. However, the above double decomposition method still has a large amount of unreacted fatty acid or fatty acid contained in the fatty acid metal salt, resulting in the defect of low product purity. For example, in the USSR patent SU 379565, the double decomposition method is used to generate iron stearate. Fatty acid is converted into ferric stearate, so 7-10% unreacted sodium stearate will remain in the product. Since sodium stearate increases the difficulty in filtering the product, it is usually necessary to reduce it to stearic acid in commercial processes. In US Patent 3840512, although it is confirmed that fatty acids and fatty acid metal salts have a synergistic effect in the photolysis reaction, which will accelerate the photolysis; however, due to the low molecular weight of the fatty acid, it is easy to migrate when added in the plastic metamorphosis. ) To the surface of the plastic, in addition to affecting the secondary processing of the plastic itself (such as printability, sealing, etc.), it will also cause uneven distribution of the concentration of stearic acid in the plastic, resulting in the decomposition rate of the product with the storage environment , Time or product location. In order to reduce the residual content of stearic acid, the process usually uses a large amount of solvent to clean, but this method will increase the production cost and easily cause environmental pollution. The third method is the exchange method, this method A 4 (210X297 public transmutation) 205543 A6 B6 Printed by the Central Standards Bureau of the Ministry of Economy V. 'Invention Description (3) is mainly used to produce trivalent or tetravalent high-purity fatty acid metals For salts, the reaction is to exchange excess fatty acid with alkyl metal salt or alcohol base salt in a large amount of solvent to generate fatty acid salt and alcohol, and the residual fatty acid is then washed with solvent. Japanese Patent Laid-Open No. Sho 62-120339 is a patent for producing iron stearate by the exchange method. The reaction is to dissolve excess fatty acid and Fe (0CH) 3 in THF to produce iron stearate. Due to this method A large amount of THF is used as the reaction solvent, which increases the production cost and easily causes pollution problems. Since this reaction is carried out with excess fatty acids, about 90% of the fatty acids cannot be reacted and are discharged as the solvent increases the cost of the product. To weaken its competitiveness. In order to eliminate the defects of the above three processes, the present invention improves the compound decomposition method, mainly by the acid-base characteristics of the reactant itself, by the way of alternating solution addition, to force the unreacted fatty acid to follow the entanglement reaction, without the need for organic solvents After cleaning, you can obtain fatty acid gold salt with good color, fine powder and high purity. In addition to effectively reducing production costs, it has been successfully applied to photodegradable plastics as an effective light sensitizer. In the present invention, a fatty acid with a nitrate number of 6 to 25 and hydrogen gas are contained at 60t: ~ 901C to perform saponification reaction in water to produce fatty acid sodium, and then a metal salt aqueous solution is added to the reaction tank to control the temperature at 60¾ ~ Between 90 * 0, complex decomposition reaction can be carried out to produce fatty acid gold salt. After the reaction is completed, the water is filtered off, and then an aqueous solution of sodium hydroxide is added to saponify the remaining unreacted fatty acids to form fatty acid sodium, and the pH of the reaction is controlled to be above 7 (generally controlled between 7 and 10), After the temperature of the anti-tank tank is increased to the reaction temperature, add an acidic metal salt aqueous solution to partially saponify the fat (please read the precautions on the back before filling in this hundred) • Pack. • Order. • Line.

Invention Explanation (6) As shown in Figures (5) to (8), the FTIR analysis of Figures (5) and (6) shows that the stearic acid absorption peak at 1707 (^ 4) is no longer present after being adjusted by the repeated acid halide. The DSC graphs in Figures (7) and (8) can also confirm that the low-melting stearic acid disappears obviously after the acid-base adjustment. [Example 3] Weigh 250g of stearate in Examples 1 and 2. 4750g of low-density PE (Taiju NA207-66, the same below) is kneaded with a double roller at 140 ° C for 5 to 10 minutes, and then crushed into a concentrate with a stearate content of 5PHR using a granulator. After mixing with PE, it is blown into a PE film of 0.03 ~ 0.04mm with a bag blowing machine. By changing the blending ratio of the concentrate and PE, different concentrations of photodegradable PE can be obtained. Decomposable PE film, placed in Xenon arc lamp acceleration test machine, in which the xenon arc light source is treated with an appropriate mask to make it light The intensity distribution is similar to that of the light. Place the sample at 508mm away from the light source and rotate it around the light source to obtain a uniform exposure effect. Control the temperature in the testing machine to 35 ± 5% and the temperature to 401C. Observe daily The sample records the time of destruction and fragmentation. The shorter the fragmentation time, the faster the photodecomposition rate. Table (1) The data shows that the photolytic plastics containing different concentrations of stearate photosensitizers are exposed to xenon arc lamps. It can be seen from the actual results that the iron stearate or cerium stearate synthesized by this patent has good photodegradability, and can effectively reduce the PE degradation and breakage time from more than 1000 hours to 200 ~ 600 hours. To achieve the purpose of photodecomposition. The speed of photodecomposition can be controlled by adding different types of stearate or the amount of addition. (Please W1?
