Embodiment Construction

[0010] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0011] The color-absorbing sheet regeneration process is characterized in that it comprises the following steps:

[0012] (1) Heat the color-absorbing sheet to a molten state, add adsorbent, flame retardant, antistatic agent, and curing agent to form a mixture;

[0013] (2) The temperature of the mixture is gradually cooled down to room temperature at a rate of 5-10 degrees Celsius per minute, and it is left to stand at 0-4 degrees Celsius for 10-30 minutes, and the first product is obtained by cooling and molding;

[0014] (3) Compress the first product into tablets.

[0015] In a specific embodiment, in step (1), the temperature is heated to 220 degrees Celsius. In step (1), the adsorbent is an active solid cationic etherification agent. In step (2), the temperature of the mixture was gradually lowered at a rate of 6 degrees Celsius per minute until it dropped to...

Abstract

The invention relates to a regeneration process of a color-absorbing sheet. The regeneration process comprises the following steps: heating a color-absorbing sheet to a molten state, adding an adsorbent, a flame retardant, an antistatic agent and a curing agent for formation of a mixture; gradually cooling the mixture at a rate of 5-10 DEG C per minute until the mixture is cooled to a room temperature, performing standing at a condition of 0-4 DEG C for 10-30 minutes, performing cooling molding to obtain a primary product, and performing tabletting forming on the primary product. Compared withthe prior art, the process provided by the invention has the beneficial effects that the regeneration of the color-absorbing sheet is realized, the adsorbent is supplemented in the regeneration process for ensuring the color absorption effect, the forming process is controllable and the forming effect is good through the proper cooling method, and the flame retardancy and the antistatic propertyare improved through the addition of the flame retardant and the antistatic agent.

Description

technical field [0001] The invention relates to a process for regenerating a color-absorbing sheet. Background technique [0002] For the color-absorbing film that has exceeded the shelf life, if it is discarded, it will cause waste of resources and pollution of energy; and if it is recycled, and the method of ensuring its excellent performance and reducing production costs is urgently needed for further research. Contents of the invention [0003] In order to solve the problems of the prior art, the object of the present invention is to provide a regeneration process of the color-absorbing sheet that realizes the regeneration of the color-absorbing sheet, and supplements the adsorbent during the regeneration process to ensure the color-absorbing effect. [0004] In order to achieve the above goals, the present invention adopts the following technical solution: the regeneration process of the color-absorbing sheet, which is characterized in that it includes the following s...
