Abstract

The invention provides pentane type composite polyether, which comprises the following components: polyether polyol 8210H, polyether polyol SA460, foam stabilizer, polyurethane synthesis catalyst, pentane foaming agent and water. In the pentane type composite polyether, pentane is used as the foaming agent; the pentane foaming agent has the advantages of low GWP value and zero ODP value and completely conforms to the environmental protection requirements for replacing HCFC-141B in the industry of a solar water heater, while the cost is low. The composite polyether overcomes the shortcoming of low compatibility between pentane and polyether and has high compatibility with pentane, high flow property and good foaming effect; and the viscosity of the composite polyether is suitable for the production technology of the solar water heater. The composite polymer has obvious advantages on application in the industry of solar water heater. The rigid polyurethane foam prepared by the action between the composite polymer and isocyanate has high heat conductivity and size stability.

Description

technical field [0001] The invention relates to the field of polyurethane rigid foam foaming, in particular to a pentane-type combined polyether, and the invention also relates to a composition containing the pentane-type combined polyether, and a composition prepared from the pentane-type combined polyether. The obtained polyurethane rigid foam and its application. Background technique [0002] With the wide application of rigid polyurethane foam, its negative impact on the environment has attracted more and more attention. my country's refrigerator freezer industry has basically shifted from HCFC-141B-type combined polyether to cyclopentane-type combined polyether. However, in the solar energy industry, HCFC-141B combined polyether is still the main product. However, as a transitional product, HCFC-141B will still cause damage to the atmospheric ozone layer. Under the catalysis of low-carbon economy, "green" polyurethane rigid foam with low global warming potential (GWP...
