This invention belongs to the field of silicone rubber technology and relates to a flame-retardant compounded silicone rubber and its preparation method. The invention involves first adding methyl vinyl silicone rubber raw material, precipitated silica, hydroxyl silicone oil, zinc stearate, silane coupling agent, and composite flame-retardant filler to a kneader for kneading. After kneading, heat treatment, and cooling, compound A is obtained. Then, compound A is mixed evenly with a platinum-containing flame-retardant additive in a specific ratio on a two-roll mill to obtain the flame-retardant compounded silicone rubber. The platinum-containing flame-retardant additive is a compound of platinum compound and vinyl amino silicone oil at a mass ratio of 1:0.5~1. This method is simple, and the prepared compounded silicone rubber has high flame-retardant properties. It utilizes a combination of platinum compound, nitrogen-containing organic compound, and composite flame-retardant filler, resulting in a strong synergistic flame-retardant effect. It also offers advantages such as good roller workability, high processing efficiency, and minimal yellowing of vulcanized samples, making it easy to promote and apply.

The invention discloses a high-thermal-conductivity flame-retardant organic silicon pouring sealant for a power battery module as well as a preparation method and application of the high-thermal-conductivity flame-retardant organic silicon pouring sealant. The pouring sealant is composed of a component A and a component B, wherein the component A contains vinyl-terminated polysiloxane, a composite heat-conducting filler, a synergistic flame retardant, a cross-linking agent and an inhibitor; and the component B contains vinyl-terminated polysiloxane, a composite heat-conducting filler, a synergistic flame retardant and a platinum catalyst. The composite heat-conducting filler is prepared from modified spherical aluminum oxide and flaky boron nitride according to a specific proportion, and the synergistic flame retardant is prepared by compounding encapsulated red phosphorus and a platinum compound. The component A and the component B are mixed according to the ratio of 1: 1 and then cured to form the elastomer with high thermal conductivity (greater than or equal to 2.0 W / m.K), high flame retardance (UL94 V-0), low stress and high reliability. The pouring sealant disclosed by the invention is particularly suitable for a power battery module needing efficient heat management and extreme safety.

In the present invention, a block copolymer containing a biocompatible polymer block and a polyamino acid block, and a micelle containing an oxidized platinum compound exhibit significantly lower distribution of platinum to bone marrow than a reduced platinum compound. In other words, myelosuppression, which is one side effect, can be prevented, and thus white blood cell production is not inhibited. Further, by using the micelle and an immune checkpoint inhibitor in combination, the activity of T cells, which are a type of white blood cells, is maintained, and thus a drug combining the two is useful in the treatment and / or prevention of cancer.
