preparation example 1

[0070] Add 3kg of 40% ethylenediamine aqueous solution (molecular weight 60) into a transparent quartz glass reactor, stir to dissolve, seal the reactor, then, under constant stirring, control the temperature between 40-65°C, and pass carbon dioxide into In the reactor, control the pressure not to be higher than 0.3MPa, control the temperature and react for 10 hours, release the pressure and release the product after the temperature is lowered to below 40°C. Compound 1 was obtained. pH≥7.5, decomposition temperature is 42°C-70°C.

preparation example 2

[0072] The 50% diethylenetriamine aqueous solution (molecular weight 103) of 3kg is joined in the transparent quartz glass reactor, stirs to dissolve, seals the reactor, then under constant stirring, controls the temperature between 40-65 ℃, will Pass carbon dioxide into the reactor, control the pressure not to be higher than 0.3 MPa, and control the temperature for 10 hours to react. After cooling down to below 40°C, release the pressure and release the product. Compound 2 was obtained. pH≥7.5, decomposition temperature is 42°C-70°C.

preparation example 3

[0074] Add 3kg of triethylenetetramine (molecular weight 146) and 1.8kg of water into a transparent quartz glass reactor, stir to dissolve, seal the reactor, and then control the temperature between 40-65°C under constant stirring, Pass carbon dioxide into the reactor, control the pressure not higher than 0.3MPa, control the temperature and react for 10 hours, release the pressure and release the product after cooling down to below 40°C. Compound 3 was obtained. pH≥7.5, decomposition temperature is 42°C-70°C.

Abstract

Blowing agents comprising polyamines and alcoholamine salts and their use in polyurethane continuous board foam materials. Disclosed is a kind of polyurethane blowing agent comprising polyamine salt and alcohol amine salt, and this blowing agent comprises: 1) the first kind of compound mixture (M1) comprising the organic polyamine salt compound class with following general formula (I) : A ‑ B + (I), where B + is the cation of organic polyamine B, A ‑ Yes: CO 3 2‑ , HCO 3 ‑ , or CO 3 2‑ with HCO 3 ‑ 2) comprising N-monohydroxypropyl / monohydroxyethyl-ammonium carbonate compound with general formula (II) and N,N'-bis(hydroxypropyl / hydroxyethyl) with general formula (II) base)-ammonium carbonate compound of the second compound mixture (M2): (RN + H 3 )(N + H 4 )CO 3 2‑ (II), or (RN + H 3 ) 2 CO 3 2‑ (III), in the formula, R is the combination of hydroxypropyl and hydroxyethyl; the molar ratio of the monoalcohol amine compound of the general formula (II) and the diol amine compound of the general formula (III) is 1:0 to 1 :2.5. Blowing agents are suitable for use in the preparation of polyurethane continuous board foam materials.

Description

technical field [0001] The present invention relates to an organic polyamine salt compound having an anion as a CO2 donor, a process for its preparation and its use as a blowing agent, more specifically, providing an organic polyamine having not only an anion as a CO2 donor but also an organic polyamine as a catalytic group Novel organic ammonium salt compound with solubilizing group, its preparation method and its application in the preparation of polyurethane continuous board foam material. The present invention relates to polyurethane blowing agents comprising polyamine salts and alcoholamine salts and their use for (preparing) polyurethane continuous board foam materials. [0002] technical background [0003] As a new polymer material, polyurethane rigid foam is light in weight, high in strength and has extremely low thermal conductivity. Automobiles, refrigerators and freezers and other household appliances and other industries. The most important raw material in the ...
