Background
The liquid silicone rubber is an elastomer rubber with excellent performance formed by crosslinking and curing on the basis of medium-low viscosity linear polyorganosiloxane, and has various advantages of excellent insulativity, moisture permeability, chemical resistance, high temperature resistance, cold resistance and the like. The crosslinking mechanism can be divided into two types of condensation type and addition type, wherein the condensation type liquid silicone rubber is crosslinked and cured by absorbing moisture in the environment, has long curing time and is not suitable for occasions needing rapid curing. Correspondingly, the addition type liquid silicone rubber can be quickly cured in a short time at room temperature or in a heating state, so that the addition type liquid silicone rubber has wide application in the fields of electronics and electrics, precision manufacturing, optical fiber protection and the like. The addition type silicone rubber currently applied to the above fields generally needs to work in some high-temperature or high-voltage environments, and is easy to age or burn. Although the residual platinum metal catalyst in the addition type silicone rubber can effectively inhibit the decomposition and gasification of polysiloxane, the flame retardant property of the silicone rubber cannot be effectively improved. If the commonly used flame-retardant filler is used, the silicone rubber cannot keep better transparency, so that the silicone rubber is not suitable for encapsulation protection in some occasions.
After being inquired: the two-component addition type liquid silicone rubber prepared by the method comprises a component A and a component B in a mass ratio of 2: 100-10: 100, wherein the component A comprises the following raw materials in parts by mass: 95-105 parts by mass of vinyl silicone oil, 2.0-5.0 parts by mass of platinum catalyst, 0.5-1.0 part by mass of accelerator and 0.1-0.2 part by mass of flatting agent; the component B comprises the following raw materials in parts by mass: 95-105 parts of base rubber, 1.0-5.0 parts of hydrogen-containing cross-linking agent, 0.05-0.1 part of inhibitor and 15-50 parts of vinyl silicone oil. Wherein the base rubber consists of 100 parts of vinyl silicone oil and 25-35 parts of white carbon black. The invention has the advantages that: the addition type liquid silicone rubber has the advantages of strong poison resistance, strong bonding performance, high vulcanization speed, high transparency, good plumpness and high mechanical strength, but has poor leveling property, relatively low tensile strength and tearing strength of the cured silicone rubber, can not effectively resist flame in a high-voltage or high-temperature environment, and is not suitable for encapsulating electronic components.
Therefore, the transparent bi-component flame-retardant liquid silicone rubber filling material and the preparation method thereof are provided, the silicone rubber filling material with good leveling property is provided, and silicone rubber formed after mixing and curing of the silicone rubber filling material has the characteristics of high tensile strength and tearing strength, excellent flexibility, good mechanical vibration resistance, high transparency and good flame-retardant effect, and is suitable for filling and sealing silicone rubber for electronic components.
