Embodiment Construction

[0017] The features and technical contents of the relevant patent applications of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings.

[0018] The present invention provides a filamentous thermal insulation material. The filamentous thermal insulation object 5 is mainly composed of a first granular material 2 made of polylactic acid mixed with an additive 1 to form a combined granular material 3. The combined granular material 3 passes through a spinning device. 4. A filamentous thermal insulation material 5 is made, wherein the additive 1 is a mixture comprising nanosized carbon black 1A, radioactive minerals 11 , calcium silicate 12 and marine biological calcium 13 .

[0019] The first granular material 2 of the present invention is a material made of polylactic acid that can be decomposed by itself, has high radiation degradation and has high water permeability and air permeability...

Abstract

The invention discloses a filamentous warm substance. The filamentous warm substance is mainly prepared from a first granular material and an additive through mixing by a spinning unit, wherein the first granular material is prepared from polylactic acid; the additive is a mixture containing nanoscale carbon black, radioactive mineral, a calcium silicate substance and marine biological calcium. The filamentous warm substance can have spontaneous decomposition, high radiation degradation and high water permeability and breathability, can increase the tensile strength, hardness, tear resistanceand wear resistance, insulate and resist ultraviolet rays, dissipate and conduct static electricity, shield electromagnetic waves and the like and has heat stability and low heat conductivity by meansof the additive.

Description

technical field [0001] The present invention refers to a thermal insulation material, in particular to a polylactic acid fusion waste recycling and utilization to produce a low-cost filamentary thermal insulation material. Background technique [0002] Generally, commercially available clothes or bedding with thermal insulation effect are mostly made of hollow chemical fibers or down feathers. The hollow chemical fibers will consume a large amount of crude oil reserves of the earth itself, and will also produce a lot of pollution during the manufacturing process. Therefore, the production of chemical fibers must have the problem of not complying with environmental protection. In addition, at present, most of the raw material sources of down feathers are obtained by live plucking, otherwise they are obtained by dehairing and screening after slaughtering. And if these down feather raw materials use live plucking, it is also against the current moral standards of most people. ...
