Description

[Technical Field]

[0001] The present invention relates to the field of cosmetic massage head technology, particularly to the formulation and manufacturing process of cosmetic optical silica gel massage head. [Background technology]

[0002] Cosmetics: Preparations (excluding soaps) used on the human body to beautify, maintain, or change one's appearance (e.g., for appearances), or preparations used to clean, stain, remove, correct, or protect the skin, nails, nails, eyes, or teeth. Cosmetics are widely used by individuals to modify or improve their appearance, for example, to respond to fashion trends or as an expression of individuality. Traditional cosmetics are not simply applied, but sometimes supplemented with devices to further enhance the effectiveness of the cosmetics. Massage heads have taken advantage of this opportunity. They are often made of hard materials.

[0003] The prior art has the following defects or problems.

[0004] Conventional cosmetic massage heads have relatively low impact resistance and are prone to tearing and deformation after a relatively long usage cycle. Furthermore, various problems are likely to occur during the manufacturing process of conventional cosmetic massage heads due to temperature changes. For example, serious deformation and cracking occur at high temperatures, and the thermal conductivity and die-casting integrity of the manufactured product cannot be guaranteed, resulting in a relatively low level of comfort for the human body. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION The present invention aims to provide a cosmetic optical silica gel massage head formulation and its manufacturing process in order to address the shortcomings of the prior art and solve the problems presented in the background art. [Means for solving the problem]

[0006] To achieve the above object, the present invention provides the following technical solutions.

[0007] The cosmetic optical silica gel massage head formulation comprises component A and component B, and component A comprises 91.8% polymethylsiloxane, 4.95% hydroxysilicone oil, 2.75% stearic acid, and 0.5% platinum catalyst in weight parts; The component B contains the following raw materials in parts by weight: 91.8% polymethylsiloxane, 4.2% hydroxysilicone oil, 1.6% hydrogen-containing silicone oil, 2.3% stearic acid, and 0.1% ethynylcyclohexanol.

[0008] In a preferred embodiment, the platinum catalyst is a tetramethyldisiloxane platinum complex.

[0009] The present invention further provides a manufacturing process for a cosmetic optical silica gel massage head formulation, the manufacturing process comprising: Step 1: preparing material components A and B based on the above weight parts, and injecting them into a static mixer in a 1:1 ratio using a silica gel supply system; The feeding system includes step 2, injecting the mixture from the static mixer into the cannon screw of the silica gel syringe; Step 3: Injecting the thoroughly mixed silica gel material into the mold from the syringe barrel; Step 4: evacuating the mold when the mold clamping pitch is 1 mm; Step 5 is to perform high-temperature vulcanization molding after the mold is completely closed. Step 6 includes opening the mold and using air blowing to bond the artificially released product to produce an optical silica gel head product.

[0010] In a preferred embodiment, in step 4, when the clamping pitch of the mold is 1 mm, the duration for evacuating the inside of the mold is 2 seconds.

[0011] In a preferred embodiment, in step 5, the front mold temperature is controlled at 140°C, the rear mold temperature is controlled at 135°C, and the high-temperature vulcanization is performed for 125 seconds. [Effects of the Invention]

[0012] Compared with the prior art, the present invention provides a cosmetic optical silica gel massage head formulation and its manufacturing process, which has the following beneficial effects:

[0013] The cosmetic optical silica gel massage head formulation has good fluidity, high transparency, high strength, high tensile strength and good tear resistance. These raw materials do not contain heavy metals or aromatic hydrocarbon solvents, are non-toxic to the human body, are biocompatible, and are more comfortable to touch. Furthermore, by adopting the above manufacturing process, serious discoloration and deformation due to temperature changes during the manufacturing process and cracking during the high-temperature sintering process are less likely to occur, which effectively improves the high permeability and solidity of the product, and improves the surface strength and tensile strength of the product, thereby improving the service life of this cosmetic optical silica gel massage head. DETAILED DESCRIPTION OF THE INVENTION

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative effort are within the scope of protection of the present invention.

[0015] In this embodiment, the cosmetic optical silica gel massage head is formulated as follows: Component A is 91.8% polymethylsiloxane, 4.95% hydroxysilicone oil, 2.75% stearic acid, and 0.5% platinum catalyst. Contains the following raw materials by weight: polymethylsiloxane 91.8%, hydroxysilicone oil 4.2%, hydrogen-containing silicone oil 1.6%, stearic acid 2.3%, ethynylcyclohexanol 0.1%.

[0016] Here, the blending ratio of component A to component B by weight is 1:1.

[0017] Here, components A and B are both liquid viscous and stored separately, and have a slow structured hardening time and a shelf life of up to one year.

[0018] Here, the platinum catalyst is a tetramethyldisiloxane platinum complex.

[0019] Based on the above cosmetic optical silica gel massage head formulation, a manufacturing process for the cosmetic optical silica gel massage head formulation is proposed.

[0020] Step 1: Injecting components A and B into a static mixer in a 1:1 ratio using a silica gel delivery system; The feeding system includes step 2, injecting the mixture from the static mixer into the cannon screw of the silica gel syringe; Step 3: Injecting the thoroughly mixed silica gel material into the mold from the syringe barrel; Step 4: When the clamping pitch of the mold is 1 mm, the inside of the mold is vacuumed for 2 seconds; After the mold is completely closed, the temperature of the front and rear molds is controlled, the front mold temperature is 140°C, the rear mold temperature is 135°C, and the molding is carried out after 125 seconds of high-temperature vulcanization. After the mold is opened, the optical silica gel head product is finally produced, and the artificial release product is bonded using air blowing (step 6).

[0021] The platinum catalyst in component A is a tetramethyldisiloxane platinum complex, which can accelerate the vulcanization rate. Component B can control the vulcanization rate, and after thorough mixing, it is thermally vulcanized and molded, which is advantageous for accurately controlling the vulcanization time. Until the material is fully vulcanized, it has a certain fluidity, allowing it to be molded into various complex structured products, and is used to mold the massage head of the cosmetic bottle in this embodiment.

[0022] It should be noted that in step 4, if the clamping pitch of the mold is 1 mm, the inside of the mold is evacuated for 2 seconds. In step 5, the front mold temperature is 140°C, the back mold temperature is 135°C, and the high temperature vulcanization is performed for 125 seconds.

[0023] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention has been described in detail with reference to the above embodiments, but those skilled in the art may modify the technical solutions described in each of the above embodiments or replace some of the technical features with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
