Hard polyurethane pouring composite structure thermal insulation integrated building block and preparation method thereof
The invention discloses a rigid polyurethane pouring composite structure thermal insulation integrated building block and a preparation method, the rigid polyurethane pouring composite structure thermal insulation integrated building block comprises a building block body, the middle part of the building block body is internally provided with a first pouring cavity; the upper side and the lower side of the first pouring cavity are each provided with a layer of second pouring cavity, the interior of each second pouring cavity is divided into at least n first cavities which are independent of one another, n is a positive integer larger than or equal to 1, and the first pouring cavities are filled with first heat preservation layers. The rigid polyurethane thermal insulation material can be firmly adhered to the hole cavity wall of the finished hollow building block, the thickness of the wall can be reduced according to the same index requirement for meeting the energy conservation of the wall, and the row number of the hole cavities needing to be filled with the rigid polyurethane can be designed according to reasonable energy conservation. Due to the fact that the heat conductivity coefficient performance of the hard polyurethane is excellent, the energy-saving requirement can be met only by pouring 30%-50% of the hole ratio of the building block, the wall thickness can be greatly reduced, and especially in severe cold and cold areas, the energy-saving index requirement can be met, and the wall thickness can be greatly reduced.
本发明公开了一种硬质聚氨酯灌注复合结构保温一体砌块及制备方法，包括：砌块本体，所述砌块本体的中部内设有第一灌注腔；在所述第一灌注腔的上下两侧各设有一层第二灌注腔，所述第二灌注腔内被分隔为至少n个相互独立的第一空腔，其中，n为≥1的正整数，所述第一灌注腔内填充有第一保温层。可将硬质聚氨酯保温材料与成品空心砌块孔腔壁牢固粘连，并可根据满足墙体节能同一指标要求减小墙体厚度，并可按合理节能设计需要灌注硬质聚氨酯的孔腔排数。因硬质聚氨酯导热系数性能优异且一般只须灌注砌块孔洞率的30％～50％则可达到节能要求，又能大幅减小墙体厚度，特别是严寒和寒冷地区既能达到节能指标要求仍可大幅减小的墙体厚度。
