Formula and preparation method of missile box shell material

Abstract

The invention relates to the technical field of missile box manufacturing, and discloses a formula of a missile box shell material. The formula is prepared from the following raw materials in parts by weight: 15-20 parts of nano zirconium oxide, 15-25 parts of resin, 10-15 parts of aramid fiber, 10-15 parts of a flame retardant, 12-18 parts of a silane coupling agent, 5-10 parts of a toughening agent and 8-12 parts of an antioxidant. The invention discloses a preparation method of the missile box shell material. The preparation method comprises the following steps: (1) heating resin at a high temperature to enable the resin to be in a molten state, adding nano zirconium oxide, a flame retardant, a silane coupling agent, a flexibilizer and an antioxidant, and uniformly stirring; (2) adding aramid fibers into the uniformly stirred mixture in the step (1), and uniformly stirring; and (3) putting the uniformly stirred mixture in the step (2) into a mold, standing, airing and molding. Through the proportion of the raw materials and the corresponding preparation method, the manufactured material has excellent high temperature resistance, fire resistance and pressure resistance, can protect missiles from being damaged by the environment, and is light in mass and labor-saving to carry.

Description

technical field [0001] The invention relates to the technical field of missile case production, in particular to a formulation and preparation method of a missile case shell material. Background technique [0002] The missile box is a box used for loading and transporting missiles, and is a direct carrier and protective tool in the storage and transportation of airborne missiles. The missile box is generally divided into an outer shell and an inner carrier, and the outer shell protects the entire inner carrier and the missile placed on the inner carrier. [0003] At present, most of the existing missile boxes use wooden packaging boxes with separate upper and lower boxes. Ordinary wooden packaging boxes are heavy, labor-intensive to carry, and the outer wall is prone to damage or permanent deformation. It cannot adapt to high-temperature fire environments, nor can it adapt to humid environments. , it is difficult to avoid damage to missiles in various environments, which se...
