Problems solved by technology

[0005] Existing indoor insulation materials mostly use benzene board, but its disadvantages are that it will release harmful gas, not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, and other Resources are limited and difficult to recycle
From the point of view of environmental protection, cork insulation effect is good, but the cost is too high
[0006] In addition, during the use of interior wall insulation materials, condensation water is prone to be generated, and the generation of condensation water will greatly affect the insulation effect of the material

Abstract

The invention relates to a preparation method of a composite insulation board. The preparation method is characterized by comprising the following steps of: (a) uniformly mixing first polyester staple fibers and fibers A; (b) performing opening and carding on the mixed fibers to form a fiber web; (c) uniformly spraying a phosphorus-nitrogen based flame retardant or a phosphorus based flame retardant on the surface of the fiber mesh; (d) performing needling, first rolling and heat setting on the fiber net processed in the step (c) to obtain an insulation board body; and (e) adhering aluminium-foil paper or aluminium-foil cloth to the upper surface and the lower surface of the insulation board body obtained in the step (d), and performing second rolling on the insulation board body to obtain the composite insulation board. According to the preparation method, the polyester staple fibers are adopted as insulation materials, the two fibers can be adhered together without adhesives, and the composite insulation board is free of harmful substances and peculiar smell and is environment-friendly. The aluminium-foil paper or the aluminium-foil cloth can be adhered to the insulation board body, so that the composite insulation board has better heat-insulation and moisture-proof effects; and the composite insulation board can have a function of absorbing sound to lower noises.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a novel composite thermal insulation board. Background technique [0002] BP's World Energy Statistical Yearbook shows that in 2010, China surpassed the United States to become the world's largest energy consumer. China's energy consumption accounted for 20.3% of the world's total, surpassing the United States' 19%. [0003] Large-scale energy consumption has led to "coal shortage", "oil shortage" and "electricity shortage" in turn. Therefore, saving energy, especially reducing the consumption of fossil resources has become a major issue affecting our future development. [0004] In our daily life, maintaining a constant indoor temperature will make us feel more comfortable. For example, heating in winter and cooling in summer can only be done by consuming fossil resources. According to statistics, during the air-conditioning season, the consumption of a...
