Mite-killing, degerming and deodorizing polyurethane foam material and preparation technology thereof

Abstract

The invention provides a mite-killing, degerming and deodorizing polyurethane foam material and a preparation technology thereof, and relates to the technical field of polymer materials. The polyurethane foam material is mainly prepared from, by mass, 900-1000 parts of polyether polyol, 450-650 parts of isocyanate, 20-100 parts of a chain extender, 40-50 parts of water, 10-80 parts of silicone oil, 2-3 parts of a tin catalyst, 3-8 parts of an amine catalyst, 30-100 parts of activated carbon, 50-100 parts of nanometer titanium dioxide, 5-25 parts of azadirachtin and 5-25 parts of spirodiclofen, and a mass ratio of the azadirachtin to the spirodiclofen is (1-2):(1-2), and preferably 1:1. The mite-killing, degerming and deodorizing polyurethane foam material solves the technical problems of low mite killing and degerming efficiency and short effect keeping time of existing polyurethane foam materials, can adsorb formaldehyde gas and peculiar smells, and also can fundamentally kill bacteria and remove mites, so the mite-killing, degerming and deodorizing polyurethane foam material provides guarantee for the health of people.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyurethane foam material for killing acarids, degerming and deodorizing and a preparation process thereof. Background technique [0002] Polyurethane foam materials have been widely used in people's daily home life, such as mattresses, sofas, pillows, car cushions, pillows and soft furnishings, etc., mostly because of their porous and elastic characteristics to give people a soft and comfortable feeling. For this reason, although existing polyurethane foam material can absorb moisture, it is not easy to distribute moisture, so it is very easy to receive dirt, stink, breed germs and breed mites, which is unfavorable for hygiene and brings potential safety hazards to people's health. At present, direct sunlight is generally used to sterilize polyurethane foam materials. The efficiency of sterilizing and sterilizing is low, and the effect is maintained for a short peri...

AI Technical Summary

Problems solved by technology

[0004] One of the objects of the present invention is to provide a kind of polyurethane foaming material for killing mites, degerming and deodorizing, so as to alleviate the problem that the existing polyurethane foaming materials usually use direct sunlight to kill mites and eliminate bacteria, and the efficiency of killing mites and bacteria is low. And its effect is maintained for a very short time, and it is impossible to fundamentally sterilize and remove mites.
