Problems solved by technology

However, with the further improvement of building energy saving and fire protection requirements, people gradually discovered its shortcomings. The fire resistance of styrene board is poor. When polystyrene burns, it will release more than 10 kinds of toxic gases, which directly cause air pollution.
Moreover, the degradation cycle of polystyrene is long, which is easy to cause white pollution

Description

technical field [0001] The invention relates to a thermal insulation material and a preparation method thereof, in particular to a urea-formaldehyde foam plastic insulation board and a preparation method thereof. Background technique [0002] Using benzene board as a building material has the advantages of light weight, heat preservation, heat insulation, and simple construction, so it is widely used in building material insulation facilities. However, with the further improvement of building energy saving and fire protection requirements, people have gradually discovered its shortcomings. The fire resistance of styrene board is poor. When polystyrene burns, it will release more than 10 kinds of toxic gases, directly causing air pollution. Moreover, the degradation cycle of polystyrene is long, which is easy to cause white pollution. Contents of the invention [0003] The purpose of the present invention is to provide a urea-formaldehyde foam insulation board to solve the...
