Problems solved by technology

[0002] Clothes are clothing for people to keep warm and protect themselves. Ordinary clothes rely on the air in the middle to keep warm. The amount and fluidity of air directly determine the warmth of clothes. There is a certain exchange between the air in ordinary clothes and the outside world, reducing the temperature of clothes Warmth retention ability, down jackets have good warmth retention properties, but the price of down with good bulkiness is high, and ordinary inflatable clothing has the problem of airbag collapse or stretching, which reduces the comfort and heat preservation ability of use

Abstract

The invention discloses a heat-reflection heat-insulation film and a preparation method thereof. The heat-reflection heat-insulation film includes the following raw materials, by weight, polyester, polyglycol ether and aluminum powder. The preparation method includes the following steps: material preparation, material feeding, addition of the aluminum powder, preparation of the heat-insulation film, treatment in a moulding drying box, rolling-up of large films and cutting and packaging of the film. The heat-reflection heat-insulation film is environment-friendly and safe, is good in extendable performance, is very easy to maintain, is free of any influence on the functions of the film under dust, washing agent residues and salts, has excellent prevention and protection effects to various virus, bacteria and body fluid, has excellent insulation effects to various chemical substances, is excellent in bio-adaptability, is suitable for being used in medical products, has an excellent heat-insulation function both internally and externally, has a certain protective effects on discomfort feelings due to instant condensation at exterior, is excellent in heat-insulation performance, is excellent in waterproofing and windproof property, is moisture-permeable and is water-washing-resistant, can isolate bacteria and can reduce wind-cold effect.

Description

technical field [0001] The invention relates to a thermal insulation film, in particular to a heat reflective thermal insulation film and a preparation method thereof. Background technique [0002] Clothes are clothing for people to keep warm and protect themselves. Ordinary clothes rely on the air in the middle to keep warm. The amount and fluidity of air directly determine the warmth of clothes. There is a certain exchange between the air in ordinary clothes and the outside world, reducing the temperature of clothes Warmth retention ability, down jackets have good warmth retention properties, but the price of down with good bulkiness is high, and ordinary inflatable clothing has the problem of air bag collapse or stretching, which reduces the comfort and heat preservation ability of use. [0003] In order to keep the human body warm and breathable, light and comfortable, waterproof and windproof, and environmentally friendly in the winter season, at the same time, the huma...
