Problems solved by technology

[0002] The existing board insulation materials are mainly used as rock wool board, polyurethane board, benzene board, etc. Rock wool board is mainly used in building exterior wall insulation, fireproof A-level material, but the disadvantages are poor insulation effect and poor waterproof performance
Polyurethane boards have good thermal insulation effect, but poor fire resistance, and the applicable range is -50—100°C
Benzene board: poor thermal insulation effect, high thermal conductivity, harmful to human body

Abstract

The invention provides a nano polyester superinsulation board. Nano vitrified microbeads are doped in premixed polyester in the mass ratio of 13%-15%, and a material A is prepared through low-speed stirring; besides, vitrified microbeads are doped in isocyanate in the mass ratio of 11%-14%, and a material B is prepared through low-speed stirring; the material A and the material B are mixed in theproportion of 1:(1-1.5) for a catalytic reaction, finally, molding is performed, and the board is obtained. The nano polyester superinsulation board has the benefits as follows: the use temperature ofthe nano polyester superinsulation board is subzero 100 DEG C to 250 DEG C, the fireproofing grade is grade B1, no pollution is caused during construction, the board is convenient and firm to mount,seamless joint of boards is realized, the heat conduction coefficient is smaller than or equal to 0.027 w / m.k, and the nano polyester superinsulation board can be placed in any special-shaped industrial structure for thermal insulation.

Description

technical field [0001] The invention relates to an inorganic material, in particular to a nanometer polyester super heat insulation board. Background technique [0002] The existing board insulation materials are mainly rock wool boards, polyurethane boards, benzene boards, etc. Rock wool boards are mainly used in building exterior wall insulation and fireproof A-level materials, but the disadvantages are poor insulation effect and poor water resistance. Polyurethane boards have good thermal insulation effect, but poor fire resistance, and the applicable range is -50-100°C. Benzene board: poor thermal insulation effect, high thermal conductivity, harmful to human body. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a nano polyester super heat insulation board. [0004] The technical solution adopted by the present invention to achieve the above purpose is: nano-polyester super heat-insulating board, which is made...
