Problems solved by technology

These organic solvents volatilize quickly and are toxic to a certain extent. They are very harmful to the human body and have a strong irritant to the human respiratory tract. Severe cases can cause coma and shock. Long-term exposure can damage the human nervous system, kidney and liver; The toxic and harmful substances in the preparation process will also be discharged into the surrounding rivers and the atmosphere through water and air, seriously polluting the local environment, and bringing health violations to people's production and life, and the public's daily life

Description

technical field [0001] The invention relates to a polyurethane color paste, in particular to a preparation method of a water-based polyurethane color paste. Background technique [0002] At present, all polyurethane color pastes produced in China contain organic solvents, most of which are dimethylformamide (DMF), butanone (MEK), acetone (ACT), toluene (TOL) and other benzene solvents. These organic solvents volatilize quickly and are toxic to a certain extent. They are very harmful to the human body and have a strong irritant to the human respiratory tract. Severe cases can cause coma and shock. Long-term exposure can damage the human nervous system, kidney and liver; The toxic and harmful substances in the preparation process will also be discharged into the surrounding rivers and the atmosphere through water and air, seriously polluting the local environment, and bringing health violations to people's production and life, and the public's daily life Contents of the inve...
