| titleOfInvention | A kind of high-density fiberglass board and preparation method thereof |
| abstract | The invention discloses a high-density glass fiber board and a preparation method thereof. The glass fiber board is treated with a modified resin with a modifier, and then the high-density glass fiber board is soaked in it. After soaking, the glass fiber board is pressed and dried to obtain High-density glass fiber board; when the modified resin is blended with the modifier, the hydroxyl group in the modified resin molecule reacts with the isocyanate groups at both ends of the modifier to form a hyperbranched structure, which cooperates with the polyethersulfone in the modified resin molecule to make the resin The toughness is greatly improved and the mechanical properties of the glass fiber board are improved. At the same time, the spiro ring structure of the side chain is opened under the action of hydrogen ions, and the chemical bonds in the molecule are transferred between atoms, which can make the resin material expand and prevent The glass fiber board has the problem that the resin shrinks and affects the normal use. |
