Embodiment 1

[0018] A multi-component, multi-boundary layer composite thermal insulation material, which is formed by arranging the following thermal insulation materials in sequence and bonding each other. The thermal insulation material has a thermal insulation capacity of 1.03-1.45clo and a moisture permeability of 6200-8214g / m 2 .24h, air flow is 2617~3267ml / m 2 .s; the composition of the thermal insulation material includes: ultra-fine polypropylene spunbond non-woven fabric air main barrier layer, infrared radiation bonding layer, polyester / acrylic melt-blown imitation down main air retention layer, infrared radiation air barrier bonding layer, Three-dimensional high-crimp hollow polyester air trap layer. The three-dimensional high-curl hollow polyester air retention layer is an elastic support layer, and the air retention layer is processed by mixing coarse denier polyester, fine denier polyester and bonding fibers, wherein the weight parts of the coarse denier polyester are 70, and...

Embodiment 2

[0025] A production method of a multi-component, multi-boundary layer composite thermal insulation material, the thermal insulation material comprising: superfine polypropylene spunbonded non-woven fabric air main barrier layer, infrared radiation bonding layer, polyester / acrylic melt-blown imitation down main air Retention layer, infrared radiation air barrier adhesive layer, three-dimensional high crimp hollow polyester air retention layer; its production steps are:

[0026] a. Mix 5% nanometer far-infrared radiation powder with polypropylene masterbatch and extrude through screw extrusion equipment, and use spunbond process to form a net to form ultrafine polypropylene spunbond non-woven fabric air main barrier flakes;

[0027] b. Blow 25-50% polyester thick and short fibers to the polypropylene fibers sprayed from the spinneret through the side blowing system, and form polyester / acrylic melt-blown imitation down main air retention layer flakes through the laying and folding...

Abstract

The present invention relates to a kind of multicomponent and multiple boundary layer composite heat insulating material and its production process. The composite heat insulating material is produced through arranging and adhering the following layers: superfine polypropylene non-woven fabric layer as the main air blocking layer, infrared radiation layer, down-like polyester/polypropylene layer as the main air trapping layer, infrared radiation and air blocking layer, and air holding hollow 3D crimping polyester layer. It has the thermal protection quality of 1.03-1.45clo, vapor transfer rate of 6200-8214g/sq m .24h, and air permeability of 2617-3267 ml/sq m .s. The composite heat insulating material has the advantages of being waterproof, poromeric, wind-proof, heat insulating and light.

Description

technical field [0001] The invention relates to a multi-component, multi-boundary layer composite heat-retaining material and a production method thereof. The material is composed of multiple composite layers, has relatively high heat-retaining capacity, and has good moisture permeability and air permeability. Background technique [0002] Usually, traditional thermal insulation materials are made of wool, cotton, or chemical fiber into felts, wadding and other thermal insulation layers. In use, there are disadvantages such as heavy wearing, inconvenient movement, and single function. They are no longer suitable for some special occasions, especially Wearing in the alpine region seriously affects the ability of the wearer to resist the cold and their range of activities. At present, the research and development of cold-proof and heat-preserving materials are developing towards the direction of high heat preservation, light weight, flexibility, beautiful appearance and multi-...
