Abstract

The invention provides a polyester resin as well as a stirring reactor and application thereof. The polyester resin is prepared from the following raw materials: tetrabromophthalic anhydride, chlorendic anhydride, tetrachlorophthalic anhydride, neopentyl glycol, polycarbonate diol, a tin catalyst, a cross-linking monomer, acetone, triethylamine and deionized water. A water-based coating is prepared from the polyester resin, a pigment, a filler, a film formation additive, a wetting dispersant, a polyether defoaming agent, a flatting agent, a cobalt salt dryer, an antibacterial agent and deionized water. The polyester resin has excellent water resistance, abrasion resistance, weather resistance and flame resistance. A polyester resin stirring reactor is capable of more uniformly stirring theraw materials of the polyester resin, directly filtering the mixed polyester resin and improving the quality of the polyester resin. When the polyester resin is applied to a water-based coating, thewater resistance, the abrasion resistance, the weather resistance and the flame resistance of the water-based coating can be improved; and the comprehensive properties of the water-based coating can be improved.

Description

technical field [0001] The invention belongs to the technical field of polyester resins, and in particular relates to a polyester resin, a stirred reactor and its application. Background technique [0002] Polyhydric alcohols and polybasic acids undergo polycondensation reactions, and the resulting polymer macromolecular main chain contains many ester groups. This polymer is called polyester resin. It is mainly used in the coatings industry. Traditional polyester resins are water-resistant , wear resistance, weather resistance and flame retardancy are not particularly good, and the traditional polyester resin mixing and stirring device is relatively simple, it is impossible to mix the polyester resin raw materials evenly, and the larger particles in the polyester resin are not removed , thus affecting the quality of polyester resin. Water-based paint is a relatively new type of paint in the paint market. Water-based paint uses water as a solvent, which saves a lot of resour...
