Description
Technical field
The present invention relates to a kind of sun power foamed material, particularly a kind of environmental type polyurethane foam material that does not destroy atmospheric ozone layer.
Background technology
At present, urethane is as solar energy thermal insulation material, and turnout is increasing.General sun power is with the combined polyether of urethane, and for having mixed the compound of pneumatogen, whipping agent is prone to produce volatilization in combined polyether; And whipping agent is fluorine-containing whipping agent, and the urethane of producing has dissipation effect to atmospheric ozone layer.Though utilize HCFC-141b CFC alternative-11 now, atmospheric ozone layer dissipation index decreases, terms of settlement that neither be final; The also useful pentamethylene in Europe is made floride-free whipping agent now, but inflammable with the urethane of its production.Also have employing full water foamed, but the urethane thermal conductivity that adopts full water to generate is excessive, is unfavorable for insulation.
Summary of the invention
The present invention provides a kind of environmental type polyurethane foam material that does not destroy atmospheric ozone layer in order to overcome above deficiency, and has insulation and fire-retardant effect.
The present invention realizes through following measure:
Sun power foamed material of the present invention is prepared from according to following materials of weight proportions and method:
(1) press 89-91.5% polyethers, 0.5-3.0% silicone oil, 0.5-2.5% suds-stabilizing agent, 1.5-3% catalyzer and 1.5-3% auxiliary agent, the 20-40 order flakey white mica of 1-4% gets compound A through the reaction kettle thorough mixing;
(2) by material HFC-245fa: water is that the weight ratio of 3 ~ 10:1 mixes, and gets compound C;
(3) by compound A: compound C is that the weight ratio of 1:0.05 ~ 0.3 is even with above raw materials mix, makes compound B;
(4) by isocyanic ester: compound B is that the weight ratio of 1.10 ~ 1.30:1 foams above raw materials mix through 100bar～150bar High Pressure Gun, obtains urethane sun power foamed material after the 45-65 ℃ of curing.
In the sun power foamed material step (3) of the invention described above, compound A: the weight ratio of compound C is preferably 1:0.15; In the step (4), isocyanic ester: the weight ratio of compound B is preferably 1.25:1.
The solar energy thermal insulation material of the invention described above, described polyether viscosity are 300-550mpas, and functionality is 3.0-8.0.
After above material mixing, guaranteed that the urethane after the foaming has enough intensity, viscosity is less simultaneously, good fluidity.
The present invention is the main raw material of urethane; After earlier thick polyethers and compound C being mixed by a certain percentage; Isocyanic ester and compound are after high velocity impact mixes in High Pressure Gun; Be filled in the cavity of solar water container and foam, through can not destroyed the solar energy thermal insulation material of atmospheric ozone layer behind the hot setting.
Mica is a kind of layer silicate mineral that contains water, and mica powder has unique acidproof, alkaline-resisting, chemical stability, also has good insulation performance and thermotolerance, uninflammability, preservative property.Solar energy thermal insulation material of the present invention; Select to add the 20-40 order flakey white mica of some amount; Because the flakey mica is laminar structured, its surface has reflection function, can sunlight reflection; Increase the heat-insulating property of lagging material, its heat insulation effect is better than common polyurethane material.In addition, add a certain amount of mica, can use lagging material of the present invention to have fire-retardant effect.Solar energy thermal insulation material of the present invention; Owing to used HFC-245fa and water as whipping agent; The cost of both having avoided whole use HFC-245fa to bring increases; Avoided using the heat-insulating property of full water as whipping agent reduction water tank again, whole cost does not increase, and atmospheric ozone layer dissipation index ODP=0.Atmospheric ozone layer dissipation index ODP=0, environmental protection.
