Isocyanates and thioisocyanates, such as 1,4-CYCLOHEXANE DIISOCYANATE, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.
High-hardness and high-transparency weather-resistant TPU material and preparation method thereof
The application discloses a kind of high hardness, high weather-resistant TPU material and preparation method thereof, the TPU material includes by weight fraction: 30~60 parts cyclohexane polyol, 30~60 parts cyclohexane diisocyanate, 0.3~2 parts antioxidant, 0.05~1 parts lubricant, 0.05~0.5 parts wax powder, 0.01~0.5 parts catalyst.The application adopts double symmetry cyclohexane aliphatic ring structure, molecular chain arrangement is neat, phase region size is less than visible light wavelength, with high hardness, high transmittance and low haze;Pure aliphatic ring structure eliminates yellowing from the source, and has excellent weather resistance and aging resistance;Double cyclohexane skeleton forms steric barrier, has outstanding hydrolysis resistance, acid and alkali resistance, fuel resistance, while high temperature mechanical retention rate, creep resistance and dimensional stability are excellent, and can be widely used in diesel filter oil cup, high temperature sealing element, outdoor transparent structural member and other high-end scenes.
