Abstract

The invention belongs to a novel polyurethane-thioether foam plastic. The novel polyurethane-thioether foam plastic comprises the following components in parts by mass: 40-80 parts of dimethicone, 30-70 parts of polyether glycol, 30-110 parts of dibutyltin dilaurate, 40-100 parts of toluene diisocynate, 10-60 parts of glycerol, 30-50 parts of tween-80 and 40-120 parts of distilled water.

Description

technical field [0001] The invention belongs to a novel polyurethane-sulfide foam and belongs to the technical field of material chemical industry. Background technique [0002] Water is the source of life and a basic condition for national economic development and human existence. at 5.1 x 10 8 km 2 Of the total surface area of ​​the Earth, 71% is covered by water. However, 97.3% of this water is sea water, fresh water only accounts for 2.7% of the total water, and only 0.2% of the fresh water can be exploited and utilized by humans. With the progress of human beings and the development of science, environmental pollution has become increasingly serious, and a global water resource crisis has emerged. Especially in densely populated large cities, the amount of water used for domestic drinking water and industrial production water is increasing day by day, and the contradiction between supply and demand of water is getting bigger and bigger. In 1977, the United Nations ...
