Embodiment 1

[0030] according to figure 1 , this embodiment proposes a formula of infant grade silica gel, a formula of infant grade silica gel and its preparation method, including the following raw materials by weight: 70-90 parts of raw materials for component A, 70-90 parts of raw materials for component B 0.05-0.1 parts of vulcanizing agent, 5-10 parts of cross-linking agent, 5-10 parts of white carbon black, 3-5 parts of food grade colorant, 5-9 parts of antibacterial additive, 5-10 parts of silicon micropowder and antistatic 3 to 5 doses.

[0031] Including the following raw materials by weight: 80 parts of raw materials for component A, 80 parts of raw materials for component B, 0.07 parts of platinum catalyst, 8 parts of crosslinking agent, 8 parts of white carbon black, 4 parts of food grade colorant, 7 parts of antibacterial additive, silicon 8 parts of micro powder and 4 parts of antistatic agent.

Embodiment 2

[0049] according to figure 1 , this embodiment proposes a formula for infant grade silica gel, including the following raw materials by weight: 90 parts of raw materials for component A, 90 parts of raw materials for component B, 0.1 parts of platinum catalyst, 10 parts of crosslinking agent, and 10 parts of white carbon black 5 parts, 5 parts of food-grade colorant, 9 parts of antibacterial additive, 10 parts of silicon micropowder and 5 parts of antistatic agent.

[0050] The vulcanizing agent is a platinum catalyst, and the platinum catalyst itself is a platinum catalyst with high activity and high catalytic efficiency, without side reactions, and has the advantages of good stability and strong toxicity resistance. During the process, do not encounter sulfides, nitrides, phosphides, organic metals, etc., which will cause poisoning of the platinum catalyst and will not cause a sulfidation reaction. When this happens, the platinum catalyst needs to be regenerated.

Embodiment 3

[0067] This example proposes a formula for infant grade silica gel, including the following raw materials by weight: 70 parts of raw materials for component A, 70 parts of raw materials for component B, 0.05 parts of platinum catalyst, 5 parts of crosslinking agent, and 5 parts of white carbon black , 5 parts of antibacterial additives, 5 parts of silicon micropowder and 3 parts of antistatic agent.

[0068] The vulcanizing agent is a platinum catalyst, and the platinum catalyst itself is a platinum catalyst with high activity and high catalytic efficiency, without side reactions, and has the advantages of good stability and strong toxicity resistance. During the process, do not encounter sulfides, nitrides, phosphides, organic metals, etc., which will cause poisoning of the platinum catalyst and will not cause a sulfidation reaction. When this happens, the platinum catalyst needs to be regenerated.

[0069] The crosslinking agent is polymethylhydrogensiloxane.

Abstract

The invention provides a formula and a preparation method of infant grade silica gel. The infant grade silica gel comprises the following raw materials in parts by weight: 70-90 parts of a component A raw material, 70-90 parts of a component B raw material, 0.05-0.1 part of a vulcanizing agent, 5-10 parts of a cross-linking agent, 5-10 parts of white carbon black, 3-5 parts of a food grade coloring agent, 5-9 parts of an antibacterial additive, 5-10 parts of silica powder and 3-5 parts of an antistatic agent. The liquid silica gel is prepared by adopting the two-component silica gel as a raw material, the process is simple, operation is rapid, the antibacterial additive is introduced to improve the antibacterial performance of the silica gel, then the silica powder is introduced to form a conductive layer on the surface of the liquid silica gel, so that the surface resistivity is reduced, and then the silica powder is matched with the antistatic agent to improve the anti-static performance of theliquid silica gel, so that the silica gel is adapted to infants; in addition, in the preparation process of the silica gel, a gradual heating mode is adopted to ensure the uniformity of vulcanization.

Description

technical field [0001] The invention relates to the technical field of silica gel preparation, in particular to a formula of infant grade silica gel and a preparation method thereof. Background technique [0002] Silica gel, also known as silicic acid gel, is a highly active adsorption material, which is an amorphous substance. Its main component is silicon dioxide, which is chemically stable and non-combustible. Because various types of silica gel are formed due to different manufacturing methods Different microporous structures, at the same time, due to the chemical composition and physical structure of silica gel, it has many characteristics that other similar materials are difficult to replace, such as: insoluble in water and any solvent, stable chemical properties, strong alkali, hydrogen fluorine Does not react with any substance other than acid; [0003] Because there are many types of silica gel, some types of silica gel still contain certain harmful ingredients, es...
