Embodiment Construction

[0009] The production recipe of this environment-friendly water-based polyester resin is composed of the following component ratios (parts by weight), 310 parts of sodium hydrogen sulfoaryl polyhydroxy acid, 1406 parts of isophthalic acid, 1.4 hydroxymethylcyclohexane 130, 172 parts of trimethylglutaric acid.

[0010] The polyester resin of the above formula is produced by the following preparation method. First, add polyhydric alcohol and polybasic acid to the reaction kettle, and stir slowly; then raise the temperature to 120°C for 2 hours, and then reflux; raise the temperature to 140°C for 2 hours, and pass a small amount of nitrogen. Dehydration: raise the temperature to 180°C, add catalyst, dehydrate 80%, then raise the temperature to 210°C and react for 16 hours. After the measured value reaches the standard, cool down to 110°C, and the material can be discharged through the flaking machine. Its main performance indicators are as follows;

Abstract

The invention discloses an environment protective typed aqueous polyester resin, which comprises the following steps: 296-360g sodium hydrosulfoaryl polyhydroxylic acid, 130 -166g m-phthalic acid, 120-144g 1. 4 hydroxymethyl cyclohexane and 168-180g trimethyl glutaric acid. The making method comprises the following steps: adding polyol and polyatomic acid in the autoclave; stirring slowly and evenly; heating to 120 deg. c for 1-2h; adding catalyst; dehydrating by 80%; heating to 200-220 deg. c for 15-16h; cooling to 100-150 deg. c after reaching the standard; discharging through piece-forming machine.

Description

technical field [0001] The present invention relates to a kind of polyester resin, more specifically relates to a kind of waterborne polyester resin. Background technique [0002] At present, polyester resins are widely used in industrial production, but most of them are solvent-based. At present, the series of solvent-based polyester resins produced by SK Chemicals Co., Ltd. in Korea are widely used. There is a problem of organic solvent residue in use, which is not environmentally friendly. Requirements, for this reason with water-based polyester resin instead of solvent-based polyester resin to become the subject of people's research, the book abstract number published in 2003 is 200322058 Chinese Chemical Engineering Abstracts introduced the annual volume period is 003, 33 (3), periodical title It is a journal of "Painting Industry", and a water-based polyester resin is disclosed on pages 9-12 of the journal, which is based on water-based functional monomers, neopentyl g...
