[0059]

[0060]

[0061] The above performance test results show that the present invention, through a large number of experimental screenings, adopts preferred raw materials to prepare saturated polyester resin for aluminum ceiling paint. Its hardness and processability are equivalent to those of the prior art polyester resin, but its weather resistance is better than There are now technical saturated polyesters that are superior. And the cost is lower than the existing technology, the environmental protection is better, and very good technical effects have been achieved.

Abstract

The invention discloses polyester resin for an aluminum coil ceiling board and a preparation method thereof. The polyester resin is prepared from dimethyl terephthalate, methylpropanediol, neopentyl glycol, hexanedioic acid, isophthalic acid, tetrabutyl titanate, triphenyl phosphite, xylene, S150 arene and n-butyl acetate. The polyester resin for the aluminum coil ceiling board prepared by a novelingredient system provided by the invention passes the performance detection; the hardness and the weather resistance performance of the polyester resin prepared by the method are identical to thoseof polyester resin in the prior art; the processing performance is better than that of the polyester in the prior art; the cost is lower than that in the prior art; the popularization and the use areeasy; good technical effects are obtained.

Description

technical field [0001] The invention relates to a resin, in particular to a polyester resin for rolled aluminum ceilings with strong environmental protection, low cost, superior performance and easy popularization and application, and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] The topcoat for coiled aluminum ceilings is usually a baking varnish system combined with highly flexible saturated polyester resin and methylated amino resin, which requires the paint film to have good hardness, flexibility and processability. Generally, saturated polyester is used for ceiling paints by using isobenzene, adipic acid, diols without β hydrogen atoms, etc. It has been proved that this polyester topcoat formula has good retort resistance, hardness, and processability. It is a classic saturated polyester resin for coil aluminum topcoat. However, in the resin formula, about 32 to 40% of the formula is used for m-benzen...
