Embodiment 1

[0021] 1, a kind of preparation method of the epoxy resin modified acrylic resin that road marking paint is used, it comprises the following steps:

[0022] (1) Add toluene and epoxy resin 601R in the following table 1 in a four-necked flask equipped with agitator, condenser, thermometer and constant pressure dropping funnel;

[0023] (2) Quantitative acrylic acid, styrene, methyl methacrylate, methyl acrylate, hydroxyethyl acrylate and dibenzoyl peroxide BPO are mixed according to Table 1, stirred evenly, and dropped into the dropping funnel;

[0024] (3) After the solvent in the four-neck flask in step (1) was heated to reflux, the acrylic acid monomer and initiator mixed in step (2) were added dropwise, and the dropwise addition was completed in about 3.5 hours. Keep the temperature and continue to react for 2 hours, then add 1 part of dibenzoyl peroxide and 1 part of toluene solvent every 1 hour, and after completing 3 parts of dibenzoyl peroxide and toluene, a slightly li...

Abstract

The invention discloses epoxy resin modified acrylic resin for road marking paints and a preparation method thereof. The epoxy resin modified acrylic resin is synthesized with, by weight, 5-10% of epoxy resin, 0.1-0.5% of acrylic acid, 10-20% of styrene, 10-25% of methyl methacrylate, 8-16% of methyl acrylate, 6-15% of a hydroxy acrylic monomer, 1-5% of an initiator, and 20-40% of methylbenzene. The optimal material composition and ratio are attained by screening through massive experiments; the synthetic process and the optimal usage ratio of the materials are optimized by massive experiments; modifying is performed on the acrylic resin via the epoxy resin under the optimal conditions so that good adhesion and wear resistance are attained; excellent water resistance, weatherability and gloss can also be retained; excellent advantages are gained.

Description

technical field [0001] The invention relates to a paint, in particular to an epoxy resin-modified acrylic resin for road marking paint and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Road marking paint is suitable for traffic marking and rerouting on asphalt or concrete pavement with various flow rates. It has many characteristics such as hard paint film, wear resistance and weather resistance, good color retention and good road adhesion. Preferred marking paint for highways and high traffic roads. With the development of society, the demand for road marking paint is increasing. But there are the disadvantages of poor adhesion, poor water resistance and weather resistance in common melt-type road marking paint resins. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art, screen out the best raw material compos...
