Embodiment 1

[0024] A method for preparing a high-precision ultra-thin resin cutting sheet of this embodiment includes the following steps:

[0025] S1. Heat silicon carbide micropowder, the main raw material that has passed strict inspection, to 50°C for standby;

[0026] S2. Heat the mixing pot to 50°C, pour the heated silicon carbide micropowder into the mixing pot and stir for 3 minutes, then allow it to be heated evenly;

[0027] S3. Add phenolic resin liquid binder for mixing. After heating the raw materials, the mixed material has good uniformity and strong consistency; among them, phenolic resin binder (phenolic resin binder) refers to an organic binder for refractory materials. . It is a resin obtained by polycondensation of a mixture of benzene (or cresol, or xylenol, or resorcinol) and formaldehyde (or furfural) under the action of a catalyst. Classified by product form, there are liquid phenolic resin binders (that is, phenolic resin liquid binders) and solid phenolic resin b...

Abstract

The invention discloses a high-precision ultrathin resin cutting blade and a preparation method thereof. The preparation method comprises the following steps: S1, heating silicon carbide micro powder to 50 to 60 DEG C for later use; S2, heating used mixing equipment to 50 to 60 DEG C, pouring the silicon carbide micro powder into the mixing equipment, and stirring until the silicon carbide micro powder is fully and uniformly heated; S3, adding a phenolic resin liquid binding agent for mixing; S4, adding a phenolic resin powder binding agent, uniformly mixing, and transferring out of the mixing equipment; S5, cooling the mixed materials in a dry room, and fully infiltrating the raw materials and the phenolic resin binding agent; S6, repeatedly and evenly rolling the prepared materials into blocks through a roller press; and S7, cutting the material blocks to a certain size according to the product specification requirement, introducing the material blocks into a high-precision ceramic double-roller calender which is heated in advance to be rolled, and evenly heating the heated materials pressed by the ceramic double-roller calender. The high-precision ultrathin resin cutting blade is high in product precision, the workpiece cutting precision is greatly improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of silicon carbide processing, in particular to a high-precision ultra-thin resin cutting sheet and a preparation method thereof. Background technique [0002] The existing technology has poor uniformity in terms of mixing and roll forming. Among the materials used, there are technical problems that the pressing time of the particles is long during the use of the particles, and it is not easy to be uniform. The thickness of the produced product is large and uneven, and the production is not well controlled. . Contents of the invention [0003] In view of this, the object of the present invention is to propose a high-precision ultra-thin resin cutting sheet and a preparation method thereof, which can solve the problems of uneven mixing and thickness control. [0004] The technical solutions adopted are: [0005] A kind of preparation method of high-precision ultra-thin resin cutting sheet of the present i...
