However, the disadvantages of benzyl alcohol are also very obvious. Its low boiling point and high saturated vapor pressure make benzyl alcohol recognized as a VOC in the industry, and the trend of being banned or less used in the industry is becoming more and more obvious
However, although there are many types of epoxy resin diluents on the market, an environmentally friendly diluent that can replace benzyl alcohol has not been developed at present. The reason is mainly because benzyl alcohol has a diluting effect on epoxy resin , can also significantly promote the curing and crosslinking of epoxy resin
The lack of substances that can replace benzyl alcohol found on the market also greatly limits the green development of epoxy resin materials

Embodiment 1-9
[0064] Preparation Examples 1-9: Preparation of Arylolamine Compounds
Embodiment 1
[0066] 27.9g (0.3mol) of aniline and 0.2g of salicylic acid were added to the three-port reaction vessel, heated to 80°C, and 12g (0.1mol) of styrene oxide was slowly added dropwise under stirring. The reaction was carried out for 4 h to obtain the crude product; the unreacted raw materials were removed in vacuo to obtain the purified product A.

The invention discloses an application of aryl alcohol amines as an epoxy resin diluent and an epoxy resin composition. The application of the aryl alcohol amine as the epoxy resin diluent is characterized in that the aryl alcohol amine has a structural general formula as shown in the specification. The aryl alcohol amine compound has the advantages that the aryl alcohol amine compound is applied to an epoxy resin composition to achieve a diluting effect, meanwhile, cross-linking curing of the composition can be promoted, the curing time is shortened, the mechanical property of the epoxy resin composition is enhanced, and the aryl alcohol amine compound has the advantage of extremely low VOC (volatile organic compounds) and is suitable for preparing environment-friendly epoxy resin products.
Description
technical field [0001] The present invention relates to the application of an aryl alcohol amine as a diluent for epoxy resins and an epoxy resin composition containing the diluent. Background technique [0002] Epoxy resin is a thermosetting resin with excellent chemical resistance, good paint film adhesion, good heat resistance and electrical insulation properties, etc. It is widely used in the fields of coatings, adhesives and composite materials. [0003] In epoxy resin compositions, benzyl alcohol is used as a diluent for epoxy resins, which has the advantages of low viscosity, good dilution effect, and a certain promotion effect on the curing of epoxy resins, and is widely used in the epoxy resin industry. However, the disadvantages of benzyl alcohol are also very obvious. Its low boiling point and high saturated vapor pressure make benzyl alcohol recognized as a VOC in the industry, and the trend of being banned or less used in the industry is becoming more and more o...
