Multicomponent and multiple boundary layer composite heat insulation material and its producing method

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 rateof 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

A kind of multi-component, multi-boundary layer composite thermal insulation material and its production method technical field 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 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 t...
