Abstract
The invention relates to special conjugate polyether for a polyurethane decompression foaming process of a solar water heater. The special conjugate polyether is characterized by comprising the following materials in parts by weight: 65-85 parts of polyether polyalcohol A, 15-35 parts of polyether polyalcohol B, 2-3 parts of foam stabilizer, 0.8-1 part of composite catalyst, 0.5-0.8 part of deionized water and 5-10 parts of foaming agent, wherein the polyether polyalcohol A is one or more of YD-6250 polyether, KS-8326 polyether and DD-450L polyether; and the polyether polyalcohol B is one or more of 450M polyether, 4110 polyether and 330B polyether. The invention can regulate the arising and curing time of foam, i.e. prolong the arising time and delay the curing time so as to ensure that a small amount of foam has sufficient foaming chance under low pressure, thereby ensuring that the foam has the advantages of little filling density, uniform density distribution and low thermal coefficient.
Description
Technical field
The present invention relates to a kind of polyurethane decompression foaming process of solar water heater dedicated combined polyether.
Background technology
In recent years, solar water heater is fast development always, and the high growth rate with annual 20%～30% becomes the up-and-coming youngster who makes industry attract attention.Solar water heater water tank thermal insulation layer main raw is a urethane foam, and in urethane foam was produced, auxiliary blowing agent was generally used for reducing foam density.Recent years, auxiliary blowing agent is reduced in large quantities, not increase destruction and the Greenhouse effect to ozonosphere.Solar water heater water tank mainly adopts the normal pressure foaming technique at present, and foaming agent consumption is bigger, and the foam mean density is 40kg/m
3About, tamped density is excessive, and the density distribution inequality, and the foam thermal conductivity is higher, has influenced the manufacturing cost and the result of use of solar water heater.
