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 51, and the lining plates 6 are arranged in a spiral shape in the axial direction. The cross-sectional thickness of the liner 6 gradually increases in the clockwise direction, and the inner surface of the liner 6 is an arc-shaped surface with a smooth transition, and a plurality of grinding sheets 61 are arranged on the arc-shaped surface. Since the cross-sectional thickness 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 the waxy material, thereby making the grinding medium and The lifting height of waxy materials is higher, which improves the grinding quality and grinding efficiency.

The invention relates to the technical field of releasing agents, in particular to a manufacturing method of a releasing agent. The method comprises the following steps that firstly, modified polytetrafluoroethylene wax, modified silicon wax, microcrystalline wax and paraffin are mixed and added into a ball grinding machine for ball grinding, and waxy fine powder is obtained; secondly, the waxy fine powder in the step one is added into a stirring tank, hydrogen desulfurization de-aromatic gasoline and hydrogen desulfurization de-aromatic petroleum ether are added, and the mixture is stirred uniformly at a low speed at the temperature of 50-60 DEG C to obtain a mixed solvent; thirdly, after the mixed solvent is stirred uniformly in the step two, the mixed solvent is cooled to the temperature of 30-40 DEG C while being stirred at a low speed, then the mixed solvent is discharged and packaged, and the mixed solvent is cooled to the room temperature to obtain the releasing agent. Accordingto the method, the waxy material is subjected to ball milling to obtain the fine powder particles, the fine powder particles are directly added into the hydrogen desulfurization de-aromatic gasolineand the hydrogen desulfurization de-aromatic petroleum ether, the melting effect is reduced, the working efficiency is improved, and meanwhile, the situation that after the waxy material is cooled andthen roughened, the effect of mold release is influenced is avoided.
Description
technical field [0001] The invention relates to the technical field of release agents, in particular to a method for manufacturing a release agent. Background technique [0002] In the resin mold manufacturing industry and the industry of using molds to produce infusion products, mold release agents are often used. This is because the mold release agent can prevent resin, rubber and plastic products from adhering to the mold, avoiding poor appearance of the product and a decline in the pass rate Case. [0003] Currently, paraffin wax release agent is the most widely used in industries that require high mold surface smoothness. Because it can be painted and polished multiple times, it can make the inner surface of the mold have a high degree of smoothness, and at the same time play a role in demoulding, and finally can obtain a finished product with a smooth outer surface and fewer defects, which can greatly reduce the amount of finished products. Operations such as polishi...
