Problems solved by technology

However, there are still some deficiencies in the existing elastic mastic materials. The main reason is that the production process of elastic mastic materials is still not very mature, resulting in low production efficiency and unstable performance of elastic mastic materials, especially the control of viscosity and electrical insulation properties. And the flexibility and resilience are not ideal, so it is necessary to further study and improve this

Abstract

The invention discloses a preparation method and a product of an elastic cement gum of an elastic cement gum bumper core. The preparation method comprises the following steps: selecting and mixing methyl siloxane and phenyl siloxane, carrying out pre-polymerizing modification after adding catalyst, adding a neutralizer and a blocking agent again for blocking, and finally removing low-molecular substances to prepare a core resin product. The whole polysiloxane molecule of the core resin is in a non-polar structure. The core resin comprises the following components in parts by weight: 80-95 parts of methyl siloxane; 5-20 parts of phenyl siloxane; 0.005-0.05 part of catalyst; 0.005-0.1 part of neutralizer; and 0.1-1.0 part of blocking agent. In the invention, the resin has various excellent performances, such as cold resistance, heat resistance, elasticity and the like and can be applied to materials of the elastic cement gum bumper core for trucks or rolling stocks, and also applied to cold-resistant resin for preparing various molded and extruded products for aviation industry as well as sealing rings, spacers, tube materials and bar materials for the use of ablative resistant, aging-resistant or radiation-resistant parts.

Description

technical field [0001] The invention relates to a manufacturing method and product of an elastic resin, in particular to a manufacturing method and a product of a core elastic mastic material for an elastic mastic buffer. It belongs to the field of polymer material production. Background technique [0002] The buffer is one of the important parts of the rail transit vehicle. Its function is to ease the impact of the vehicle and reduce the longitudinal impulse of the vehicle. It can protect the vehicle during shunting operations, train starting, braking, speed regulation, and collision accidents. and the role of goods. The performance of the buffer directly affects the driving safety and passenger comfort, so all countries in the world pay attention to the development and research of buffers with good performance. Hydraulic oil, metal spring, and rubber are three commonly used buffering and damping media or materials, and the buffering and damping products made of them are ...
