On April 16, 2025, the National Intellectual Property Administration announced that Fujian Huaxia Blue New Materials Technology Co., Ltd. had applied for a patent titled “A Moisture-Curing Polyurethane Adhesive and Its Preparation Method,” with publication number CN 119823696 A and an application date of December 2024.
The patent abstract states that this invention belongs to the field of adhesive technology, specifically involving a moisture-curing polyurethane adhesive and its preparation method. The moisture-curing polyurethane adhesive is prepared using raw materials in the following weight ratios: diisocyanate; organosilicon-modified cycloalkyl polyether diol; modified cycloalkyl polyether polyol; polyether diol; polyester diol; low-molecular-weight diol; anti-aging agent; polyurethane catalyst. The beneficial effects of the present invention are as follows: The moisture-curing polyurethane adhesive obtained from the present invention contains a large amount of isocyanate groups, thereby forming a network structure with high cross-linking degree; the modified cycloalkyl polyether polyol used can react with isocyanate groups, providing excellent cross-linking performance for the polyurethane adhesive, with uniform cross-linking degree and good elasticity, resulting in the moisture-curing polyurethane adhesive having excellent heat resistance and rebound properties.
