Problems solved by technology

[0003] At present, the thermal insulation paper used in buildings is mainly divided into barrier type thermal insulation paper, radiation type thermal insulation paper and reflective thermal insulation paper. Among them, the barrier type thermal insulation paper can prevent the outdoor heat from entering the room by heat conduction, but its light transmittance is poor.
Radiant heat insulation paper radiates the heat in the building into the air through thermal radiation, reducing the temperature of the building, but the heat insulation efficiency of this method is very low
Reflective thermal insulation paper, which directly reflects solar energy into the air, but will cause light pollution to the outside

Abstract

The invention provides heat insulation paper for decorating and a preparation method thereof. The heat insulation paper is prepared from the following raw materials: inorganic fibers, wood pulp, waterborne acrylic emulsion, polypropylene oxide glycol, hexamine, octadecyl trimethyl ammonium chloride, polyvinyl alcohol, nano-silica aerogel and ethyl silicate hydrolysate. The heat insulation paper has the advantages of being resistant to high temperature, outstanding in heat insulation performance and heat insulated; in addition, the hydrophobicity is high, and the heat conductivity is low; and the temperature preserving and heat insulating effects are outstanding.

Description

technical field [0001] The invention belongs to the technical field of decorative heat insulating materials, and in particular relates to a decorative heat insulating paper and a preparation method thereof. Background technique [0002] Due to the sunlight, the temperature inside the building rises, which will increase the energy consumption of the air conditioner. In addition, for industrial plants, prefab houses or temporary buildings, etc., the indoor temperature will rise rapidly under the sun. In many cases, the effect of using air conditioning to cool down the indoor temperature is not good. It is usually the most practical way to reduce the indoor temperature by reducing the heat from sunlight entering the room. The main way to prevent the indoor temperature from rising is to make the outdoor heat (mainly the heat generated by sunlight) pass into the room as little as possible, and the indoor heat be dissipated as much as possible. [0003] At present, the thermal i...
