| titleOfInvention | Toughened modified polyformaldehyde and preparation method and application thereof |
| abstract | The invention provides toughened modified polyformaldehyde and a preparation method and application thereof, wherein the toughened modified polyformaldehyde comprises 80-87% of polyformaldehyde, 11-13% of thermoplastic polyurethane, 1-5% of lignin and 1-2% of talcum powder in percentage by weight, the sum of the weight percentages of the components is 100%, the toughened modified polyurethane is obtained by introducing the components of the lignin, the talcum powder and the thermoplastic polyurethane into polyformaldehyde and utilizing the synergistic toughening effect of the lignin, the talcum powder and the thermoplastic polyurethane, and the tensile strength of the toughened modified polyurethane can reach 56MPa, the bending modulus can reach 2230MPa, and the impact strength can reach 25kJ/m 2 The mechanical property is superior to other toughened polyformaldehyde products. |
