| titleOfInvention | High-hydroformylation-degree polyvinyl butyral resin and preparation method thereof |
| abstract | The invention discloses high-hydroformylation-degree polyvinyl butyral resin and a preparation method thereof. The polyvinyl butyral resin with the hydroformylation degree of more than 78 percent is prepared by using polyvinyl alcohol and n-butanal as raw materials and hydrochloric acid as a catalyst through low-temperature continuous condensation and recondensation, wherein the reaction temperature during the low-temperature continuous condensation is 0 to 35 DEG C; and the reaction temperature during the recondensation is 5 to 75 DEG C. According to the invention, the hydroformylation degree of the polyvinyl butyral resin is increased and the application field of the polyvinyl butyral resin is expanded. According to the polyvinyl butyral resin prepared by the existing production technology in China, the hydroformylation degree is far less than the level, and the using fields are narrow and mainly comprise the fields of coating and adhesive. The product prepared by the method of the invention is mainly applied to the industries, such as automobile industry, building industry and photovoltaic industry, with high requirements on the polyvinyl butyral resin, and has large profit space. |
