Abstract

The invention discloses an integrated spraying heat-insulating waterproof polyurethane material which is prepared in a foaming manner, and prepared from, by weight, 60-80 parts of toluene diisocyanate, 30-40 parts of polyether polyol, 6-8 parts of triethylene diamine, 0.8-1 part of catalyst, 1-2 parts of flame retardants, 0.6-0.8 part of foaming agent, 4-6 parts of dimethyl silicone fluid and 12-18 parts of deionized water. The material can be applied to water resistance, heat preservation and heat insulation of high-rise buildings, accessible roofs or roof gardens, maintenance and reconstruction of old buildings, waterproof heat-insulating engineering of various buildings such as pools and swimming pools and has the advantages of high strength, light weight, good waterproof and heat-insulating effect, excellent abrasion resistance and corrosion resistance, simple preparation process, low cost and device requirement and easiness in industrial production and has high flame retardant ability, a CFC (chlorofluorocarbon) foaming agent is omitted, energy is saved, and environments are protected.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a spray-coated polyurethane heat-preservation, waterproof and heat-insulation integrated material. Background technique [0002] Ordinary polyurethane insulation materials generally use polyether polyols with high functionality and high hydroxyl value to react with polyisocyanates to form cross-linked polymers. At present, polyurethane is used as thermal insulation, waterproof, heat insulation and other materials, and its production volume is increasing. As an excellent thermal insulation and energy-saving material, polyurethane rigid foam has great development potential in building energy conservation, and its thermal conductivity is low, only 0.018 -0.024(w / m*k), equivalent to half of EPS, is currently the lowest thermal conductivity of all insulation materials, and has good thermal performance, aging resistance, good chemical stability, excellent moisture and water resistanc...
