Abstract
A solar heat-insulating material is prepared from isocyanate and conjugate polyether at the mass ratio of (1-1.1):1. The conjugate polyether is prepared from raw materials in percentage by weight as follows: 77-80 percent of polyether, 16-19 percent of an HCFC (Hydro Chlorofluoro Carbon)-141b foaming agent, 1-2 percent of silicone oil, 0.1-1.0 percent of a foam stabilizer and 1-1.5 percent of a catalyst. The solar heat-insulating material prepared from the material with the method ensures that the foamed polyurethane has sufficient strength; and meanwhile, the solar heat-insulating material has the advantages of lower viscosity, favorable flowability, high heat insulating performance and low heat conducting coefficient.

Technical field
The present invention relates to a kind of solar energy thermal insulation material, particularly a kind of by behind dichloro one fluoroethane and the thick polyethers proportional mixing with the high energy efficiency solar energy thermal insulation material of isocyanic ester foam production.
Background technology
At present, urethane is as solar energy thermal insulation material, and turnout is increasing.Existing sun power is used the polyurethane heat-insulation poor-performing; Thermal conductivity is higher; Be about at national efficiency standard GB 26969-2011 " domestic solar hot-water system efficiency limit value and efficiency grade " under the overall situation of execution and the appearance of efficiency subsidy policy; Sun power is proposed requirements at the higher level with the polyurethane heat-insulation performance, and it is high to press for a kind of heat-insulating property, and the sun power that thermal conductivity is low is used polyurethane heat insulation material.
Summary of the invention
In order to solve the problems of the technologies described above, to the invention provides the sun power that a kind of heat-insulating property is high, thermal conductivity is low and use polyurethane heat insulation material.
The present invention realizes through following technical scheme:
A kind of solar energy thermal insulation material; Be prepared from isocyanic ester and the combined polyether mass ratio by 1 ~ 1.1:1, said combined polyether is formed by the feedstock production of following quality percentage composition: 77-80% polyethers, 16-19%HCFC-141b whipping agent, 1-2% silicone oil, 0.1-1.0% suds-stabilizing agent, 1-1.5% catalyzer.
Further, described combined polyether can also include the 20-40 order flakey white mica of 1-4%.
Described polyether viscosity is 320mpass, average functionality 4.0.
Described catalyzer is that terepthaloyl moietie, tertiary amine catalyst and the potassium oleate of 1:4:2 formed by mass ratio.
Its preparation method who adopts is following:
(1) takes by weighing 77-80% polyethers, 16-19%HCFC-141b whipping agent, 1-2% silicone oil, 0.1-1.0% suds-stabilizing agent, 1-1.5% catalyzer in the percentage composition ratio, get combined polyether through the reaction kettle thorough mixing;
(2) by isocyanic ester: combined polyether be the weight ratio of 1 ~ 1.1:1 with above raw materials mix through high-pressure foam, obtain the urethane solar energy thermal insulation material behind the hot setting.
By the solar energy thermal insulation material of above material and method preparation, 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; Earlier combined polyether being got to white batch can keeps at a certain temperature; After reaching use temperature; Isocyanic ester and combined polyether be after high velocity impact mixes in High Pressure Gun, is filled in the cavity of solar water container to foam, through obtaining heat-insulating property height, solar energy thermal insulation material that thermal conductivity is low 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.
