Abstract

The invention discloses a homogeneous non-combustible polyurethane foam heat insulating material and a preparation method thereof. The heat insulating material is prepared by reacting the following raw materials in parts by weight: 6~20 parts of polyurethane rigid foaming material, 4~20 parts of flame retardant and 60~90 parts of inorganic filler, wherein the loose packing density of the inorganicfiller is 1.0~2.0 g / cm<3>. The heat insulating material prepared by the invention has overall density between 120 and 800 kg / m<3>, compressive strength being greater than and equal to 0.10 MPa, highmechanical strength, good durability, total heat value being smaller than and equal to 3.0 MJ / kg, combustion growth rate index being smaller than and equal to 120 W / s and 600 s total heat release ratebeing smaller than and equal to 7.5 MJ, and belongs to A2 grade non-combustible material, and has high fire-proofing safety and simple preparation process, and can realize industrial production.

Description

technical field

[0001] The invention belongs to the field of new materials, and in particular relates to a homogeneous non-combustible polyurethane foam heat insulation material and a preparation method thereof. Background technique

[0002] China's economy has entered a new normal, the constraints on energy supply have intensified, and the constraints on resources and the environment have become increasingly prominent. Actively promoting building energy conservation can effectively implement my country's energy conservation and emission reduction policies and promote green, circular, and low-carbon development. Using thermal insulation materials to insulate building walls can effectively reduce energy loss and improve building energy utilization efficiency.

[0003] At present, the thermal insulation materials used in the market are mainly organic foam thermal insulation materials such as phenolic, polyurethane, polystyrene, etc., and inorganic foam thermal insulation mate...
