The hydroxyl value of 480mg KOH/g and the water content of 0.08wt.%, the second polyalcohol are adipic acid system polyester polyol, are had
The hydroxyl value of 232mg KOH/g and the water content of 0.56wt.%, the two weight ratio are 1:1), amide compound shown in formula (I),
Water and silicone surfactant mixing, as component A；It will be as the poly methylene poly phenyl poly isocyanate of component B, expansion stone
Ink and the mixture for obtaining modification high-density polyethylene according to the method for the present invention are added in component A, are stirred 15-45s, are then noted
In the cavity of the forms connection component with injection hole for entering embodiment 1, make its vertically free wxpansion in the cavities, it is existing
Field generation heat insulator.
It is found by detecting, the heat insulator has extraordinary thermal insulation effect, lead due to good pore structure
Hot coefficient is 0.0089W/ (m.k), also with good sound insulation, shockproof effect other than with good thermal insulation effect.It presses
According to GB/T14484-2008 test the compression strength of the heat insulator, compression strength 186kPa.
Comparative example 1
Embodiment 2 is repeated, differs only in be added without and obtains modification high-density polyethylene according to the method for the present invention.It measures
The compression strength of heat insulator is 92kPa.
By above-described embodiment and comparative example clearly it can be seen from using high density polyethylene (HDPE) can significantly increase it is hot absolutely
The bearing strength of edge material.
This written description discloses the present invention, including optimal mode using example, and also enables those skilled in the art
It manufactures and using the present invention.The present invention can patentable scope be defined by the claims, and may include this field skill
Other examples that art personnel expect.If this other examples have not different from the structural elements of the literal language of claims
Element, or if this other examples include with equivalent structure element of the literal language of claims without substantial differences,
Then this other examples are intended within the scope of claims.In the case where inconsistent degree will not be caused, by reference to
It will be incorporated herein in place of all references referred to herein.
