On April 18, 2026, information from the State Intellectual Property Office showed that Yuwang Jianneng Technology Co., Ltd. applied for a patent titled “A polymer composite material that catalytically degrades formaldehyde and its preparation method.”
The application publication number is CN121869360A, the application number is CN202610320752.9, the application publication date is April 17, 2026, and the application date is March 17, 2026.
The patent summary shows that the present invention relates to the field of construction technology, and in particular to a polymer composite material that catalytically degrades formaldehyde and its preparation method.
Specific steps include: determining the amount of stabilizer to add based on the melt flow rate and oxidation induction period of random copolymerized polypropylene and modifying it to obtain the first intermediate product; determining and adjusting the preset dosage ratio of the first intermediate product based on the oxidation induction period of the first intermediate product; heating and blending the raw materials in a screw extruder to obtain the second intermediate product.
material, and determine the mixing state characteristic value based on its density and the agglomeration index of the metal oxide to determine whether the mixing state of the second intermediate product meets the standard, and verify the mixing state when it does not meet the standard; adjust the screw speed of the screw extruder based on the melt color uniformity of the second intermediate product; feedback and adjust the screw speed of the screw extruder; extrude the second intermediate product and then cool it to form the product.
This invention solves the problem of uneven dispersion of nanoscale metal oxide particles leading to local formaldehyde degradation function failure.
