Problems solved by technology

[0002] Rigid polyurethane foam has good thermal insulation performance, and rigid polyisocyanurate foam has good fire resistance and high temperature resistance, but rigid polyurethane foam has poor fire resistance. The poor thermal insulation performance of foamed plastics greatly limits the practical application space of these two kinds of foamed plastics

Embodiment Construction

[0021] Please refer to the accompanying drawings for a further description of the present invention.

[0022] Such as figure 1 and figure 2 As shown, the present invention provides a polyurethane modified rigid polyisocyanurate foam PIR energy-saving insulation board, the PIR energy-saving insulation board is a PIR sandwich panel structure, or a PIR bare board structure, and the PIR energy-saving insulation board The thermal conductivity is as low as 0.018W / (m·K).

[0023] The PIR sandwich panel structure is that the middle sandwich layer is polyurethane modified rigid polyisocyanurate foam PIR macromolecular structure monomer 1, and the upper and lower sides of the middle sandwich layer are metal or non-metallic Sheet 2.

[0024] The PIR sandwich panel structure is produced by PIR foaming and composite molding or secondary composite molding after PIR foaming. The primary molding of PIR foaming and compounding is to inject the PIR raw material between the two surface laye...

Abstract

The invention relates to a polyurethane modified hard isocyanuric acid ester foamed-plastic PIR energy-saving heat preserving plate which features a PIR sandwich plate structure or a PIR plate structure. In the PIR sandwich plate structure, a middle sandwich layer is a polyurethane modified hard isocyanuric acid ester foamed-plastic PIR macromolecular structure monomer; an upper surface and a lower surface of the middle sandwich layer are metal or non-metal sheets; the PIR plate structure refers to the attachment-free polyurethane modified hard isocyanuric acid ester foamed-plastic PIR macromolecular structure monomer formed according to box type foaming. The polyurethane modified hard isocyanuric acid ester foamed plastic is a novel macromolecular structure obtained by embedding a polyurethane molecular chain into polymer isocyanuric acid ester molecular chain. The invention has the advantage that compared with polyurethane heat preserving material, the energy-saving heat preserving plate of the invention has good fireproof performance and better heat preserving property.

Description

technical field [0001] The invention relates to an energy-saving heat preservation board, in particular to a polyurethane modified rigid polyisocyanurate foam PIR energy-saving heat preservation that meets the flame-retardant B1 level fire protection requirements and has a thermal conductivity as low as 0.018W / (m·K). plate. Background technique [0002] Rigid polyurethane foam has good thermal insulation performance, and rigid polyisocyanurate foam has good fire resistance and high temperature resistance, but rigid polyurethane foam has poor fire resistance. The thermal insulation performance of foamed plastics is poor, which greatly limits the practical application space of these two kinds of foamed plastics. Contents of the invention [0003] The technical problem of the present invention is to provide a polyurethane-modified rigid polyisocyanuric acid that has the advantages of polyurethane foam and polyisocyanurate foam and is used for air-conditioning ducts, building...
