Embodiment Construction

[0017] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0018] The invention relates to a molding process of a highly light-transmitting foamed elastic material, comprising the following steps:

[0019] ①Put the body to be foamed into the reactor, and then add supercritical gas into the reactor, the pressure in the reactor is 10-60Mpa;

[0020] ②Let the to-be-foamed body be saturated in the reactor for a period of time until the to-be-foamed body is in a gas-saturated state;

[0021] ③The autoclave is depressurized at a decompression speed of 0.1-1Mpa / s, and the gas inside the foam to be expanded in a gas-saturated state is gradually released, and forms a high-transparency light-transmitting foam with cells in the range of 0.1-3mm in diameter. foam elastic material.

[0022] Preferably, the pressure release rate in step ③ is 0.1-0.5Mpa / s, so that the diameter of t...

Abstract

The invention discloses a forming process of a high light transmittance foamed elastic material. The forming process includes the following steps: (1) a to-be-foamed body is placed in a reaction kettle, supercritical gas is added to the reaction kettle, and the pressure in the reaction kettle is 10-60 Mpa; (2) the to-be-foamed body is made to saturate in the reaction kettle for a period of time until the to-be-foamed body is in the gas saturation state; and (3) an autoclave is subjected to pressure relief at the pressure relief speed of 0.1-1 Mpa/s, the gas in the to-be-foamed body in the gassaturation state is released gradually, and the high light transmittance foamed elastic material with forming holes at the diameter range of 0.1-3 mm. Compared with the prior art, the foamed elastic material obtained by the forming process has good light transmittance, and thus has widespread application in shoe sole lamplight function design.

Description

technical field [0001] The invention relates to the field of foamed elastic materials for shoe soles, in particular to a molding process of a highly light-transmitting foamed elastic material. Background technique [0002] At present, in the field of shoe soles, foamed elastic materials have been widely used as the core shock-absorbing layer of insoles. Various foamed elastic materials are basically formed by chemical foaming or physical foaming. Based on its unique characteristics, the mode is being welcomed by the market. The physical foaming process generally includes placing the foamed body in a high-pressure reactor, adding carbon dioxide or nitrogen into the high-pressure reactor, and then Keep the reactor at a higher temperature, and the pressure of the reactor is generally controlled at 10-50Mpa. In such an environment, let the foam to be expanded be saturated for 0.5-10h, so that carbon dioxide or nitrogen and other gases can be released at high pressure. The state...
