Spray rigid polyurethane foam heat insulation waterproof integrated material

Abstract

The invention provides a spray rigid polyurethane foam heat insulation waterproof integrated material. The spray rigid polyurethane foam heat insulation waterproof integrated material is double-component foamed plastic which is formed by field spraying and consists of a component A and a component B in an equal volume ratio; the component A consists of 0 to 30 weight parts of toluene diisocynate, 0 to 30 weight parts of methylene diphenyl diisocyanate, and 70 to 100 weight parts of polymethylene polyphenyl isocyanate; the component B consists of 30 to 50 weight parts of polyatomic alcohol, 10 to 20 weight parts of catalyst, 5 to 10 weight parts of foam stabilizer, 10 to 30 weight parts of foaming agent, and 10 to 30 weight parts of fire retardant; the material comprises a foamed plastic layer with fire resistance, high intensity and density, and functions of watertightness, heat insulation, corrosion prevention, solvent resistance and the like; and the material can be mainly used for the watertightness, and heat insulation and the like of various roofs, wall bodies, and large-span light metal rooves with grid structures of industrial and civil buildings, and high-rise buildings, accessible rooves or roof gardens.

Description

Technical field: [0001] The invention provides a spray-coated hard foam polyurethane thermal insulation and waterproof integrated material and a construction method thereof. Background technique: [0002] Spraying rigid foam polyurethane insulation material (hereinafter referred to as SPF) is a new type of polymer synthetic material. During decades of development, its excellent characteristics have been used in different construction industries for roof insulation, heat insulation, Sound insulation material performance is superior. SPF rigid foam roofing has been widely used in industrially developed countries such as Europe, the United States, and Japan, as well as in Hong Kong and mainland China. The market growth rate remains 3-5%, and the growth rate in the United States in 2005 was 5.6%. In the competition between sprayed SPF and laminated linoleum roofs, it has more and more obvious advantages due to its thermal insulation, water resistance, light weight, and wind res...

AI Technical Summary

Problems solved by technology

However, the existing sprayed hard foam polyurethane materials only have the function of thermal insulation. During roof construction, in addition to the thermal insulation layer, an additional waterproof layer is required.
