The invention discloses a method for preparing methyl chlorosilane, which comprises the following steps of: taking chlorosilane and methane as raw materials, respectively pretreating and mixing the raw materials, and reacting the mixed raw materials in a reactor under a heating condition to generate methyl chlorosilane. The invention further discloses a device for preparing methyl chlorosilane, which comprises a first buffer tank provided with a a first feeding pipeline and used for placing chlorosilane; a second buffer tank provided with a second feeding pipeline and used for placing methane;a reactor connected with the first buffer tank and the second buffer tank and used for reacting chlorosilane with methane; and a heating device comprising a first heater, a second heater and a thirdheater which are respectively used for heating the first buffer tank, the second buffer tank and the reactor. The raw materials are easy to obtain, the technological operation is simple, and the production cost of methyl chlor
