| titleOfInvention | Preparation method of weather-resistant toughening agent for PVC transparent product |
| abstract | The invention discloses a preparation method of a weather-resistant toughening agent for a PVC transparent product, which relates to the technical field of production and preparation of PVC auxiliaries, and comprises the preparation of an inner layer copolymer, the preparation of a middle layer copolymer and the preparation of the weather-resistant toughening agent for the PVC transparent product, wherein the inner layer copolymer is prepared by random copolymerization of 40-80 parts by weight of styrene and 20-60 parts by weight of acrylate; the middle layer copolymer is prepared by copolymerizing 0-30 parts by weight of styrene and 70-100 parts by weight of butyl acrylate; the weather-resistant toughening agent for the PVC transparent product is prepared from 50-80 parts by weight of an inner layer copolymer, 10-20 parts by weight of an intermediate layer copolymer, 10-20 parts by weight of an outer layer monomer, an emulsifier, an initiator, a cross-linking agent, a molecular weight regulator and deionized water through emulsion copolymerization. The invention solves the problem that the existing toughening agent for PVC products is easy to cause poor weather resistance of the products, and provides a novel weather-resistant toughening agent which can enhance the toughness of PVC transparent products and ensure good weather resistance of the PVC transparent products. |
