Description
Technical Field
The invention belongs to the technical field of optical processing, and particularly relates to filling glue for an optical element polishing die and a preparation method thereof.
Background
At present, the processing technology for processing optical elements in China mostly adopts a classical polishing method and a high-speed polishing method. The classical polishing method uses a polishing mold made of a metal substrate coated with polishing pitch to polish the component. The polishing pad plays a very important role in the polishing process. First, the polishing powder existing in the processing area needs to generate a force on the surface of the polishing object by virtue of the supporting action of the polishing disk, so as to realize the material removal on the surface of the polishing object. Therefore, under the action of the circular flow of the polishing solution, the micro-deformation generated by the polishing disk and the micro-hardness of the local area of the polishing disk can directly influence the acting force of the polishing powder on the surface of the zinc sulfide crystal, wherein the mechanical properties (hardness, elasticity and the like) of the polishing disk can also have very important influence on the deformation of the polishing disk, and further influence the polishing efficiency and the surface characteristics of a polished product. Second, the flow of fresh slurry into the processing region and the flow of polishing reactants out of the processing region are all through the polishing pad. Therefore, the texture characteristics (micropore shape, porosity, groove shape and distribution, etc.) of the polishing disk have an important influence on the flow and distribution of the polishing solution in the processing area, and further influence the polishing efficiency and the surface quality of the product.
In the polishing process, the main material of the working surface of the polishing die is asphalt, and the advantages are as follows: (1) the proportion of the filling adhesive can be changed according to the difference between the hardness of the infrared crystal material to be processed and the temperature of the processing environment, so that the hardness of the asphalt filling adhesive can be changed; (2) the asphalt is softened at about 60 ℃, so that the asphalt is easy to form and correct; (3) the raw material cost is low.
Chinese patent CN101993598A discloses an optical polishing film filling adhesive and a processing method thereof, wherein the optical polishing film filling adhesive comprises the following materials in percentage by weight: 5-70 parts of asphalt, 29-94 parts of rosin and 1 +/-0.1 parts of crushed degreased wool; the lens processed by the filling glue of the polishing mould has good quality and high yield.
