Abstract

The invention discloses an environmentally-friendly energy-saving polyurethane spraying composite material with ultralow density, which comprises the following components in part by weight: 20-60 parts of polyether polyol which takes glycerol as an initiator, 3-10 parts of amine catalyst, 0.5-3.0 parts of foam stabilizer, 22-30 parts of water, 30-45 parts of fire retardant and 95-120 parts of isocyanate. In the environmentally-friendly energy-saving polyurethane spraying composite material, pure water is used for replacing the traditional hydro chlorofluorocarbon (HCFC)-141b foaming agent, and the environmentally-friendly energy-saving polyurethane spraying composite material is an environmentally-friendly energy-saving polyurethane spraying foam with the ultralow density. The polyurethane spraying composite material has the ultralow density which can reach 5-10kg / m3. Because the polyurethane spraying composite material has tapping performance, the sound absorption performance can reach 70%. Meanwhile, the oxygen index of the environmentally-friendly energy-saving polyurethane spraying composite material reaches 23 and can pass the Society of Tool and Manufacturing Engineers (ASTME)-84 authentication.

Description

technical field

[0001] The invention relates to a polyurethane spraying composite material, in particular to an environment-friendly ultra-low density energy-saving polyurethane spraying composite material. Background technique

[0002] Polyurethane rigid foam is widely used in thermal insulation, refrigeration, and construction industries due to its excellent performance, but with the wide expansion of its application range, its negative impact on the environment has sounded the alarm for people. Among them, polyurethane spray coatings are mainly used in the building insulation industry, and the foaming agents used are mainly HCFC-141b and water. Foaming agents such as HCFC are Freon-type foaming agents. The use of Freon will deplete the atmospheric ozone layer and cause damage to the atmospheric ozone layer, resulting in enhanced ultraviolet radiation and threatening the survival of human beings and other earth creatures. one of the environmental problems.
