Problems solved by technology

The use of tung oil requires high-temperature refining, and the process requirements are very strict. If there are no trained workers, it will easily become gelatinous.
At the same time, there are many shortcomings in the wrinkle paint made of tung oil, such as the paint film is very easy to pulverize and yellow.
Furthermore, the use of wrinkle paint needs to be diluted with benzene, which also increases the safety hazard for the use of wrinkle paint.

Abstract

The present invention discloses a kind of alkyd wrinkles resin. The alkyd wrinkles resin comprises linolenic acid, 95% glycerine, phthalic anhydride, adduct, xylene, and diluted solvent. The present invention also discloses the preparation method of the said alkyd wrinkles resin. The present invention avoids the general existing process of high-temperature refining tung oil and many defects of winkles paint brought by adding tung oil, and makes the process of synthesizing winkles paint resin simply and easy to operate, and also saves energy. The resin-prepared winkles paint synthesized by using the present invention, has no necessary to be diluted with benzene before using, which makes it more secure and more environmentally friendly for the use of winkles paint, and meets the overall trend of current development of paints.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a novel resin and a preparation method thereof. Background technique [0002] As a kind of art paint, wrinkle paint is the same as the commonly used hammer paint and orange paint. It has a wide range of uses. It can be used on metal surfaces such as instruments, meters, hardware, security doors, etc., and has a good protective and decorative effect. According to the prior art, the resins for wrinkle paints mainly include phenolic resins and alkyd resins, and the wrinkle paints prepared by these two types of resins all need to add tung oil. The use of tung oil requires high-temperature refining, and the process requirements are very strict. If there are no trained workers, it will easily become glue. Simultaneously, there are many disadvantages in the wrinkle paint made of tung oil, such as very easy chalking and yellowing of the paint film. Furthermore, in...
