Embodiment 1

[0022] Synthesize novel polyurethane material, synthetic method is as follows:

[0023] Step 1: Synthesize by Fischer esterification method, specifically, add 2.74mL, 37.5mmol, 5 equivalents of thionyl chloride to 50ml 1,2-propanediol, react at 0°C for 20 minutes; add 20mmol L -Gln, placed in a magnetic stirrer at room temperature and stirred for 178 hours, the product was taken for thin layer chromatography, verification showed that the amino acid was completely absorbed, and a new chain compound UPAT was obtained, the structural formula is

[0024] Step 2, take a round bottom flask, dissolve 5.6g polycaprolactone diol (2.5mmol, 1.0 equivalent) and 0.74mL 1,6-hexamethylene diisocyanate (20.0mmol, 2.0 equivalent) in 50ml of anhydrous dimethyl The prepolymer is prepared in acetamide, and the reaction is carried out under high-purity nitrogen; the prepolymerization reaction condition is 85° C. for 3 hours, and the catalyst is 0.12 wt % stannous octoate.

[0025] Step 3. Add 0...

Embodiment 2

[0029] Synthesis of high-strength polyurethane containing graphene, the synthesis method is as follows:

[0030] Steps 1 to 2 are as described in Example 1, and in step 3, graphene oxide solution (GO) needs to be added to the prepolymer. The preparation method of graphene oxide solution is as follows: with reference to the method of Hummers, natural graphite is dispersed in sulfuric acid and dissolves with sodium nitrate solution, then adds potassium permanganate wherein, after standing for 12 hours, solution is mixed with hydrogen peroxide Potassium permanganate was removed, placed in a centrifuge to dissociate the solution and form distilled water and graphene oxide, and finally the graphene oxide was cleaned, and the pH level was adjusted to 6.5 to obtain a GO solution.

[0031] Put 5% GO solution and 0.5g UPAT (5mmol, 1.0 equivalent) into the prepolymer, react at 105°C for 2 hours, keep stirring during the reaction, then reduce the reaction temperature to 25°C and overnigh...

Abstract

The invention provides an ultra-insulation polyurethane energy-saving plate. Specifically, the ultra-insulation polyurethane energy-saving plate comprises an anti-corrosion layer, the lower part of the anti-corrosion layer is provided with a first heat insulation layer, the lower part of the first heat insulation layer is provided with a first flame retardation layer, the lower part of the flame retardation layer is provided with a second heat insulation layer, the lower part of the second heat insulation layer is provided with a second flame retardation layer, the lower part of the second flame retardation layer is provided with a bonding layer, and function layers are bonded through high-temperature-resistant binders. The ultra-insulation polyurethane energy-saving plate is advantageousin that the product is ultrathin, the thermal insulation performance is excellent, thermal radiation is effectively prevented, and the conduction, convection and thermal insulation performances are not lost due to the influence of extrusion of steel plates and purlins of a steel structure and a prefabricated structural building.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a super thermal insulation polyurethane energy-saving board. Background technique [0002] The insulation board is easy to understand, it is a board for building insulation. The thermal insulation board is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. It has moisture-proof and waterproof properties, which can reduce the thickness of the building's outer enclosure structure, thereby increasing the indoor use area. [0003] Common insulation boards mainly include glass wool, XPS insulation board and polyurethane composite board. Glass wool belongs to a category of glass fiber and is a kind of man-made inorganic fiber. Glass wool is a material made of molten glass fibrosis to form a cotton-like material. Its chemical composition belongs to glass and is an inorganic fiber. [0004] XPS insulation board is a rigid foam plas...
