Description
Technical field
The present invention relates to a kind of polyurethane material, be specifically related to a kind of low gas of aging resistance type polyurethane
Taste foam compositions.
Background technology
Polyurethane material is the same with other high molecular products all can give out one to some extent
Fixed abnormal smells from the patient, these abnormal smells from the patients once occur in small-sized confined space such as such as family-sized car, household etc.,
People can be allowed to produce offending sensation, it is also possible to healthy to human body produces harmful effect and damage
Evil.Therefore, the odor problem of polyurethane material causes the concern of people the most day by day.
The abnormal smells from the patient that polyurethane material gives out is the mixture of complicated VOC,
It is originated mainly following several respects:
1, the abnormal smells from the patient that free isocyanate monomer produces: prepare the main former material of polyurethane material
One of material isocyanates, monomer whose has the feature of low boiling and high-vapor-pressure, volatile to sky
Gas causes air pollution, human body is produced huge harm.
2, the abnormal flavour of aging generation: during polyurethane material is deposited, oxygen in air,
Ozone, moisture, particularly ultraviolet can cause polyurethane material itself and the oxidation of additive,
Aging, generate volatile aldehyde, ketone or other little molecule, produce abnormal smells from the patient.
3, the middle lower-molecular substance of remained unreacted.
In the production process of polyurethane material, except polyethers (ester) and isocyanates raw material
Outward, also need to add many auxiliary agents such as such as stabilizer, amines catalyst, foaming agent, fire retardant etc.,
Due to the incomplete of reaction and the difference of the extent of reaction, a small amount of unreacted middle low phase pair can be remained
The material of molecular mass, they are easy to evaporate from polyurethane material, produce abnormal smells from the patient.
