Embodiment approach
[0037] As an embodiment of the present invention, a plurality of lining plates 6 are evenly distributed on the inner wall of the inner cylinder 3 on the left side of the partition plate 51 , and the lining plates 6 are arranged in a spiral shape in the axial direction. The thickness of the section 6 gradually increases in the clockwise direction, the inner surface of the lining plate 6 is an arc surface with a smooth transition, and a plurality of grinding sheets 61 are arranged on the arc surface. Since the thickness of the section of the liner 6 gradually increases in the clockwise direction, when the inner cylinder 3 rotates clockwise, the thicker side of the liner 6 can better lift the grinding medium and waxy material, thereby making the grinding medium and the wax material better. The lifting height of the waxy material is higher, which improves the grinding quality and grinding efficiency.

The invention relates to the technical field of mold release agents, in particular to a method for manufacturing a mold release agent, comprising the following steps: S1, mixing modified polytetrafluoroethylene wax, modified silicon wax, microcrystalline wax and paraffin, and Add to the ball mill for ball milling to obtain waxy fine powder; S2, add the waxy fine powder in S1 into a stirring tank, and add hydrodesulfurized and dearomatized gasoline and hydrodesulfurized and dearomatized petroleum ether, at a temperature of 50-60 ℃ Stir at a low speed to obtain a mixed solvent; S3. After the mixed solvent in S2 is evenly stirred, cool down to 30-40°C while stirring at a low speed, then discharge the material for packaging, and cool to room temperature to obtain a release agent. By ball-milling the waxy material into fine powder particles and directly adding it to the hydrodesulfurized and dearomatized gasoline and the hydrodesulfurized and dearomatized petroleum ether, the melting effect is reduced, the work efficiency is improved, and at the same time, the coarsening of the waxy material after cooling is avoided, which will affect the desulfurization and desulfurization. mode effect.
Description
technical field [0001] The invention relates to the technical field of mold release agents, in particular to a manufacturing method of a mold release agent. Background technique [0002] In the resin mold manufacturing industry and the use of mold production to infuse finished products, mold release agents are often used. This is because mold release agents can prevent resin, rubber, plastic and other products from adhering to the mold, avoiding poor appearance of the product and lowering the pass rate. Case. [0003] At present, in industries that require high mold surface smoothness, paraffin release agent is the most widely used one. Because it can be brushed and polished multiple times, the inner surface of the mold has a high smoothness, and at the same time it plays a role in demoulding. Finally, a finished product with a smooth outer surface and fewer defects can be obtained, which can greatly reduce the amount of finished casting. It is irreplaceable for other type...
