Abstract

The invention discloses an adapter forming technology. The adapter forming technology comprises the following steps that S1, hollow glass beads, tri-ethenylidene diamine, F-12 and simethicone are weighed, are added into adipic acid polyester polyol for preparing a premixed compound solution uniformly, and then are added into a high-pressure foaming machine charging bucket, and an A component is obtained; S2, solid-state diphenylmethane diisocyanate is put into a drying oven for being heated and molten into a liquid stage, is added into the high-pressure foaming machine charging bucket, and a Bcomponent is obtained; S3, mould assembling is carried out, and preheating is carried out; S4, an adapter body is subjected to pouring forming according to a set mixing ratio of the A component and the B component; S5, the adapter body after the pouring forming is subjected to curing treatment; S6, the adapter body is obtained after demoulding; S7, an anti-friction film is subjected to hot-pressforming; and S8, the anti-friction film is pasted. With the adoption of the components and the set ratio, an obtained foaming product is higher in compression strength at the same density, the adapterforming technology has the advantages of light weight, high strength and the like, and the technology is simple and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of launch systems, and more specifically relates to an adapter forming process. Background technique [0002] The adapter (often referred to as the lateral vibration reduction support system of box-launched missiles abroad) is a key component of the storage and transportation launch box, which is installed in the annular gap between the missile and the launch box and plays a role in product storage, transportation and launch. To support, dampen, guide and control the initial disturbance during launch, fix the missile during transportation and storage, play a guiding role during launch, and fly out of the launch box with the missile. The materials used in the adapter mainly include rubber (such as natural rubber, butyl rubber, etc.), polyurethane elastomer, polyurethane foam and other materials or a mixture of the above materials, among which polyurethane elastomer and polyurethane foam are the most widely us...
