Problems solved by technology

[0007] The disclosed mold release agent is mainly designed for the adhesion problem in the forming process of non-magnetic materials, and the demoulding effect for products of different shapes (especially for ring products with a large aspect ratio) is very unsatisfactory. The qualified rate and forming quality are poor

Embodiment 1

[0018] A release agent used in the forming process of magnetic materials, which consists of the following components: graphite powder with a weight percentage of 0.1, fatty acid derivatives with a weight percentage of 0.1, paraffin wax with a weight percentage of 0.1, and dodecane with a weight percentage of 0.1 A mixture of sodium alkylbenzene sulfonate, 0.1 weight percent glyceride, and 99.5 weight percent gasoline. The mixture mixed according to the above ratio is heated to a temperature of 60-100° C., mixed and dissolved for 30-45 minutes, and the mold release agent in the forming process of the magnetic material is obtained.

Embodiment 2

[0020] A release agent used in the forming process of magnetic materials is composed of the following components: graphite powder with a weight percentage of 2, fatty acid derivatives with a weight percentage of 5, paraffin wax with a weight percentage of 2, and dodecane with a weight percentage of 0.5 A mixture of sodium alkylbenzene sulfonate, 2.5% by weight glyceride, and 88% by weight gasoline. The mixture mixed according to the above ratio is heated to a temperature of 60-100° C., mixed and dissolved for 30-45 minutes, and the mold release agent in the forming process of the magnetic material is obtained.

Embodiment 3

[0022] A release agent used in the forming process of magnetic materials is composed of the following components: graphite powder with a weight percentage of 1, fatty acid derivatives with a weight percentage of 3, paraffin wax with a weight percentage of 1, and dodecane with a weight percentage of 0.3 A mixture of sodium alkylbenzene sulfonate, 1.5 weight percent glyceride, and 93.2 weight percent gasoline. The mixture mixed according to the above ratio is heated to a temperature of 60-100° C., mixed and dissolved for 30-45 minutes, and the mold release agent in the forming process of the magnetic material is obtained.

[0023] The composition of the components of each of the above examples is shown in Table 1 below. In addition, see Table 2 for the product technical parameters of the various embodiments.

Abstract

The invention provides a releasing agent used in a process of forming a magnetic material, which comprises the following components: 0.1-2 percent by weight of graphite powder, 0.1-5 percent by weight of fatty acid derivative, 0.1-2 percent by weight of paraffin, 0.1-0.5 percent by weight of sodium dodecyl benzene sulfonate, 0.1-2.5 percent by weight of glyceride and 88-99.5 percent by weight of gasoline mixture. The invention also discloses a preparation method of the releasing agent. According to the releasing agent provided by the invention, the problem of adhesion in the process of forming the magnetic material is solved, and the surface quality of a permanent magnet material casting is improved, especially the annular permanent magnet material product with large long diameter ration; and by using the releasing agent, the surface roughness of the permanent magnet material blank product is reduced, and the forming qualified rate of products is improved.

Description

technical field [0001] The invention relates to a release agent used in the forming process of magnetic materials and a preparation method thereof. Background technique [0002] The mold release agent is a kind of isolation film applied between the product and the mold to prevent the formed metal material product from sticking to the mold, so that the product can be easily released from the mold, while ensuring the surface quality of the product and the mold are intact. [0003] Common die-casting release agents in the prior art include oil-based release agents, water-based release agents and powder release agents: [0004] Chinese invention patent application No. 200610024658.1 discloses an oil-based magnetic material release agent and its preparation method; [0005] Chinese invention patent application No.200410086761.X discloses a water-based metal mold release agent; [0006] Chinese invention patent application No. 200710051860.8 discloses a powder release agent for ...
