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 laminated composite heat preservation board and a preparation method thereof. The laminated composite heat preservation board is composed of two composite fiber boards with composite fiber cotton sandwiched in the middle. Each composite fiber board is composed of a fiber board with aluminum-foil paper adhered to the upper face and the lower face. The composite fiber cotton is composed of a fiber net with aluminum-foil paper adhered to the upper face and the lower face. The aluminum-foil paper coating the surface of the laminated composite heat preservation board has waterproof performance. The laminated composite heat preservation board is good in heat preservation and insulation performance and has the functions of absorbing sound and reducing noise. Component materials of the laminated composite heat preservation board can be recycled and used. According to the preparation method, no adhesive is added so that the method is environment-friendly, used materials are small, technology is simple, and operation is easy.

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] The "2012 China Energy Development Report" released by the China Energy Research Society shows that in 2011, my country's total energy consumption 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 is...
