Problems solved by technology

Organic thermal insulation materials have many advantages, such as light weight, good processability, high density, and good thermal insulation effect, but the disadvantages are that they are not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, and poor ecological environmental protection. The construction is difficult, the project cost is high, and its resources are limited and difficult to recycle

Abstract

The invention provides a sandwich composite thermal insulation board and a preparation method thereof. The sandwich composite thermal insulation board is composed of two composite fiber boards sandwiching composite fiber cotton; the composite fiber board is formed by laminating the upper and lower sides of the fiber board with aluminum foil paper. The composite fiber cotton is formed by laminating aluminum foil paper on the upper and lower sides of the fiber net. The aluminum foil paper coated on the surface of the sandwich composite thermal insulation board of the present invention has waterproof performance, excellent thermal insulation performance, and also plays the role of sound absorption and noise reduction, and its constituent materials can be recycled. The preparation method does not add any adhesive, is environmentally friendly, and the method of the invention uses less material, and the process is simple and easy to operate.

Description

technical field [0001] The invention relates to a sandwich composite thermal insulation board and a preparation method thereof, belonging to the technical field of building energy-saving new composite materials. Background technique [0002] According to the "2012 China Energy Development Report" released by the China Energy Research Society, my country's total energy consumption in 2011 reached 3.478 billion tons of standard coal, an increase of 7% over the previous year; in 2012, my country's total primary energy consumption was about 3.62 billion tons Standard coal, an increase of 4% over 2011. Such a large energy consumption has caused energy shortage, and also played a great role in boosting the pollution of the environment. Air conditioners have become one of the essential electrical appliances in our modern life, and their main function is to provide cooling and heating. According to statistics, in the season when the air conditioner is in use, its power consumption ...
