Description
Technical Field
The utility model relates to a bottom child of lacquer ware and contain lacquer ware of this bottom child belongs to industrial art article technical field.
Background
The lacquer (also called raw lacquer or natural raw lacquer) is coated on the surface of various devices to make daily utensils, artworks and artworks, etc., which are called lacquerwares. The process for making the lacquer comprises at least a step for making a base lacquer and a step for painting the base lacquer, and if it is desired to obtain a lacquer having a delicate design on its surface, a further step for decorating the painted base lacquer. The lacquerware is manufactured in China for more than 8000 years, and is mostly made by painting plant embryo (such as wood embryo or hemp embryo). When the plant embryo is used as the bottom embryo to manufacture the lacquer ware, in the step of manufacturing the bottom embryo, the requirements on tree species, tree age, water content and the like are extremely high, and complicated procedures are required, so that the plant embryo is generally required to be subjected to cloth mounting, ash scraping and polishing procedures for many times, and at least the ash scraping and polishing procedures are required. For example, in the method for preparing the lacquerware handicraft disclosed in the invention with publication number CN109353155A, after selecting wood and processing into a wood blank with a desired shape, the wood blank is subjected to ash coating (coating raw lacquer ash on the outer surface of the wood blank and then drying in the shade) and ash coating (decontaminating the surface of the raw lacquer ash, then coating coarse ash and then drying in the air under the light, then polishing and scraping the ash after drying in the air, then coating fine ash on the surface of the coarse ash and then drying in the light again, polishing with sand paper after drying in the air, coating slurry ash on the surface of the fine ash after polishing, then drying in the shade, and then performing fine polishing with sand paper after drying in the air, and then performing lacquering and further decoration after the procedure of coating ash and ash, namely, scraping and polishing. The requirements of plant embryo on tree species, tree age, water content and the like are extremely high, so that not only can the excellent plant embryo lacquerware be stored for a long time but also a few plant embryo lacquerware can be stored for a long time, but also the plant embryo lacquerware directly becomes a luxury product due to the complex manufacturing process, long time and high manufacturing cost, and the plant embryo lacquerware cannot be brought into ordinary families like porcelain even though the plant embryo lacquerware is a traditional three treasures in China.
Compared with the plant tire, the metal tire is far more than the plant tire in material stability, the metal matrix is directly used as the bottom tire, the operations of cloth mounting, ash scraping and the like are not needed in the process to stabilize the performance of the tire, and the manufacturing time and cost are greatly reduced. However, in the process of making a lacquerer, after each lacquering, the lacquer needs to be cured and surface-dried (at least for tens of hours or even hundreds of hours) under the condition of low temperature and high humidity (usually under the condition of 20-30 ℃ and relative humidity of 70-90%), and it is known to those skilled in the art that metal is easy to rust under the condition that the relative humidity is more than 60%, and is easy to rust under the condition that the relative humidity is as high as 70-90%, such as: copper reacts with oxygen, carbon dioxide and water in the air in humid air to generate basic copper carbonate (verdigris); iron reacts rapidly with oxygen and water in the air in humid air to produce a mixture (rust) of iron trioxide, iron hydroxide, etc.; aluminum is an amphoteric metal, is very reactive, reacts rapidly with oxygen in air to form alumina, and can continue to react in acidic or basic environments to form other products (e.g., white rust). These products all increase the original volume, and particularly with the participation of water in a humid environment, the products become loose and even fall off, thereby affecting the adhesion between the paint film and the base tire. On the other hand, since each coat of lacquer needs to be cured and surface-dried under conditions of low temperature and high humidity, in order to allow the paint film to dry in a shorter time, and also in order to avoid wrinkling due to an excessively thick layer of lacquer (e.g., the flatness of the paint film), the thinner the coat of lacquer, the better the film, however, the thinner the coat, the more the pores, which in turn provide favorable conditions for the tarnishing reaction of the metal mentioned above, and the more the paint film adhesion is adversely affected over time.
In the prior art, in order to solve the problem of poor surface adhesion of a copper tire, a lacquer is modified mostly, and the purpose of improving the adhesion on the surface of the copper tire is achieved by improving the leveling property of the lacquer. For example, patent of invention with publication number CN108944226A discloses a manufacturing process of a copper base paint device, which comprises the following steps: pretreating the surface of the copper tire to increase the surface area of the copper tire, and meanwhile, carrying out oxidative polymerization treatment on the raw lacquer to increase the crosslinking degree and the molecular weight of the raw lacquer; painting oxidized and polymerized raw paint on the surface of the copper tire for one time, and polishing for one time after the surface is cured and dried; secondly painting oxidized and polymerized raw paint on the surface of the copper tire after the primary polishing, and secondarily polishing after curing and drying; cooling after high temperature treatment, and decorating the product with the traditional lacquerware process. According to the invention, the raw lacquer is modified to match with a secondary brushing process and is polished after brushing so as to improve the roughness and wettability of the surface of the copper tire, thereby effectively improving the adhesive force of a paint film; however, the two times of curing and drying are carried out under the conditions that the environmental temperature and the relative humidity are 20-30 ℃ and 80-90%, respectively, wherein the standing and airing time of the primary curing and surface drying is 28-32 hours, the standing and airing time of the secondary curing and drying is 84-104 hours, and the defect that basic copper carbonate is easy to generate and the adhesive force of a paint film is influenced due to the fact that the copper base is placed for a long time under the high humidity condition inevitably exists. In addition, the invention directly coats the raw paint on the copper tire, and the corrosion resistance of the invention is not ideal.
Correspondingly, in the lacquerware structure manufactured by the existing lacquerware manufacturing process, the processed plant blank is directly used as a base mould, or the metal blank is directly used as the base mould, the base mould is directly provided with a lacquer film layer obtained by using lacquer, and no other intermediate layer is arranged between the blank and the lacquer film layer.
