preparation example 1

[0069] Add 15kg of triethyl orthoformate, 20kg of diethanolamine, and 10kg of water into the reactor, start stirring, control the pressure not higher than 0.1MPa, slowly raise the temperature under constant stirring, when the temperature rises to 80°C Temperature controlled reaction for 10 hours. After the reaction is completed, cool down to 50°C, then control the vacuum degree below 600 mmHg, remove ethanol under reduced pressure at a temperature below 50°C, and release the product after cooling down to below 40°C to obtain compound 1, pH ≥ 7.5, and decomposition temperature at 45 -70°C.

preparation example 2

[0071] Add 15kg of triethyl orthoformate, 13kg of monoethanolamine, and 7.0kg of water into the reactor, start stirring, slowly raise the temperature under constant stirring, and control the temperature below 100°C for 8 hours. After the reaction is completed, lower the temperature, then control the vacuum to be below 600 mm Hg, remove ethanol under reduced pressure at a temperature below 50°C, remove the vacuum, and release the product after cooling down to below 50°C to obtain two esters of triethyl orthoformate Hydrolyzed compound 2. pH≥7.5, decomposition temperature 45-70℃.

preparation example 3

[0073] Add 20kg of tripropyl orthoformate, 11kg of diethanolamine, and 10kg of ammonia water into the reactor, start stirring, slowly raise the temperature under constant stirring, and react at a temperature not exceeding 100°C for 8 hours. After the reaction is completed, lower the temperature, then control the vacuum to be below 600 mm Hg, remove unnecessary water under reduced pressure at a temperature below 50°C, remove the vacuum, cool down to below 40°C and release the product to obtain compound 3. pH≥7.5, decomposition temperature 45-70℃.

Abstract

The invention discloses a polyurethane alkaline foaming agent containing an orthoformic acid alcohol amine salt and a carbonic acid ethanolamine salt. The alkaline foaming agent has a pH value of 8.5-9.5 and comprises: 1) a first compound mixture (M1) comprising orthoformic acid alcohol amine compounds of a following general formula (I): A<->B<+> (I), wherein B<+> is a cation of an organic alcoholamine B, and A<-> is orthoformate; and 2) a second compound mixture (M2) comprising a N-monohydroxyethyl-ammonium carbonate compound of a general formula (II) and an N,N'-di(hydroxyethyl)-ammonium carbonate compound of a general formula (III): (RN<+>H<3>)(N<+>H<4>)CO<3><2-> (II), or (RN<+>H<3>)<2>CO<3><2-> (III), wherein R is hydroxyethyl, and the molar ratio of the compound of the general formula (II) to the compound of the general formula (III) is from 1:0 to 1:1.0. The foaming agent is suitable for use in preparation of a polyurethane solar foam material.

Description

technical field [0001] The present invention relates to having as CO 2 The use of organic amine salt compounds of donor anions as blowing agents, more specifically, to provide not only CO 2 The application of the new type organic ammonium salt compound with the anion of the donor and the orthoformic alcohol amine as the catalytic group and the solubilizing group in the preparation of the polyurethane solar foam material. More specifically, it relates to alkanolamine orthoformate and ethanolamine carbonate basic blowing agents and their use in the preparation of polyurethane solar foam materials. technical background [0002] 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 production of rigid polyurethane foam is the blowing agent. At present, these blowing ag...
