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.

The invention discloses a high-performance foaming material containing a thermoplastic polyurethane base material as well as a preparation method and application of the high-performance foaming material. The CHDI-based thermoplastic polyurethane in the foam material is obtained by reacting at least a component a and a component b or reacting the component a, the component b and a component c, and the component a is polyisocyanate containing 1, 4-cyclohexane diisocyanate; the component b is a polyol polymer; and the component c is a chain extender. The foaming material prepared from the thermoplastic polyurethane base material containing 1, 4-cyclohexane diisocyanate and the foaming product of the foaming material have good mechanical strength, higher elongation at break, higher toughness and high rebound resilience.

The invention discloses a CHDI type polyurethane film for laminated glass as well as a preparation method and application of the CHDI type polyurethane film. The CHDI type polyurethane film is prepared from 1, 4-cyclohexane diisocyanate, polycaprolactone polyol, an aliphatic dihydric alcohol chain extender, a catalyst and a silane coupling agent, and the content of a cis-isomer in the 1, 4-cyclohexane diisocyanate is 30%-80%. The adhesive is simple in production process, high in transparency and excellent in mechanical property, and has good adhesion to inorganic glass and PC plastic plates.
