Renewable silica gel heat transfer label and manufacturing method thereof

Abstract

The invention relates to the technical field of utilization, research and development of renewable resources, in particular to a renewable silica gel heat transfer label and a manufacturing method thereof. The renewable silica gel heat transfer label comprises a base layer, a transition layer, a first bonding layer, a raw silica gel layer, a second bonding layer, a renewable silica gel layer and asilica gel protective layer, wherein the base layer, the transition layer, the first bonding layer, the raw silica gel layer, the second bonding layer, the renewable silica gel layer and the silica gel protective layer are sequentially arranged in a laminated mode from bottom to top. According to the invention, the renewable silica gel heat transfer label is made of a renewable silica gel material; the utilization rate of renewable silica gel is remarkably increased, and the content of renewable silica gel powder in the renewable silica gel heat transfer label reaches 20% or above, which meets the global recovery standard (GRS) certification; and in the aspect of the use method of the renewable silica gel powder, the renewable silica gel powder does not need to be made into a gel solution, is directly attached to the heat transfer label and is wrapped by the silica gel protective layer, so the renewable silica gel powder is protected from falling off.

Description

technical field [0001] The invention relates to the technical field of research and development of the utilization of renewable resources, in particular to a thermal transfer label of recycled silica gel and a production method thereof. Background technique [0002] Circular economy is an economic operation model that follows the natural ecological material cycle. This economic development model can not only solve the problem of resource depletion faced by human development, but also improve the quality of the ecological environment. The relationship between economic development and environmental protection, the relationship between economy and society, and the great practical and historical significance of solving the number one problem facing human development in the new millennium (economic growth is constrained by increasing resources and environmental pressure). [0003] Circular economy is a scientific economic development model that requires the transformation of the ...

AI Technical Summary

Problems solved by technology

[0006] Silica gel is a resource that can be recycled and reused. At present, in the field of thermal transfer technology, there are technical problems that need to be further solved in the utilization rate and use method of regenerated silica gel. First, the utilization rate is low; In terms of the use of silica gel, it uses strong acid and strong alkali fission method, the production process is not environmentally friendly, and the production cost is high;
