Embodiment C-1

[0136] Add 15kg of ammonium formate, 1kg of methylamine catalyst, 10kg of water, and 5kg of ethylene glycol into the reactor, start stirring, control the pressure not higher than 0.5MPa, control the temperature below 120°C, and put 12kg of epoxy Ethane was added to the reactor in batches and reacted for 5 hours. After the reaction is completed, lower the temperature, then control the vacuum degree to be below 600 mm Hg, remove unnecessary water under reduced pressure at a temperature below 100°C, remove the vacuum, and release the product after cooling down to below 50°C. Compound C-1 is obtained. The viscosity is about 200 centipoise, pH=8.5, and the decomposition temperature is above 100°C.

Embodiment C-2

[0138] Example C-1 was repeated, except that 15 kg of propylene oxide was used instead of 12 kg of ethylene oxide, and the propylene oxide was not added to the reactor in batches, but added in one go. Compound C-2 is obtained. The viscosity is about 350 centipoise, pH=8.6, and the decomposition temperature is above 100°C.

Embodiment C-3

[0140] Add 10kg of methyl formate, 10kg of ethyl formate, 13kg of ammonia water (concentration 25wt%), and 35kg of diethanolamine into the reactor, start stirring, control the pressure not higher than 0.5MPa, and slowly heat up under constant stirring , when the temperature was raised to 100°C, the temperature was controlled and reacted for 15 hours. After the reaction is completed, the temperature is lowered, and then the vacuum degree is controlled to be below 600 mm Hg, and the methanol and ethanol are removed under reduced pressure at a temperature below 100°C, and the vacuum is removed, and the temperature is lowered to below 50°C to release the product. Compound C-3 is obtained. The viscosity is about 400 centipoise, pH=9, and the decomposition temperature is higher than 100°C.

[0141] The above-mentioned compounds C-1, C-2 and C-3 immediately release carbon dioxide gas and a small amount of carbon monoxide gas when contacted with isocyanate, which overcomes the shortc...

Abstract

The invention discloses a formic acid organic amine salt compound with the following general formula (I) A<n->[B<m+>]p. In the formula (I), A<n-> is formate; B<m+> is or comprises ammonium ion and / or organic amine B positive ion; m=1-10; 0<p<=n / m; the formula (I) compound has at least one hydroxyalkyl connected with an N atom, that is to say, has an alcohol amine residue. The compound can be a polyurethane foaming agent or polystyrene foaming agent or polyvinyl chloride foaming agent.

Description

technical field [0001] The present invention relates to having as CO 2 The formic acid organic amine salt compound of donor and the purposes thereof as blowing agent, more specifically, provide not only have as CO 2 Donor formate and have hydroxyalkyl or hydroxyalkylalkoxy groups as solubilizing groups or C2-C14 hydrocarbon groups (such as 2-chloroethyl, 3-chloropropyl or phenethyl) as solubilizing groups The novel organic ammonium salt compound of group, and its application in foaming materials such as polyurethane foam or PVC foaming material or polystyrene foaming 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 production of rigid polyurethane foam is the blowing agent. At present, these blowing agents are c...
