Abstract

The invention discloses an epoxy asphalt quick-drying material, which comprises the following components in parts by mass: 25-30 parts of epoxy resin, 80-100 parts of solid red lead, 10-15 parts of zinc chrome, 4-8 parts of dimethylbenzene, 2-4 parts of methylbenzene, 6-8 parts of cyclohexanone, 20-28 parts of anthracene oil, 20-25 parts of coal tar pitch, 5-8 parts of curing agent, 1-1.5 parts of n-butyl alcohol, 12-15 parts of mica powder, 10-14 parts of talc powder, 1-2 parts of cured tung oil and 5-20 parts of diethylenetriamine. The time for surface dry is within 1.5-3 hours and the time for hard dry is within 20-22.5 hours, and the product is 80-100s in viscosity, less than or equal to 80 microns in fineness, and high in ductility and shear resistance. The product has temperature resistance and cold resistance as well as excellent fatigue resistance and aging resistance, and can be produced on a large scale to replace the conventional material continuously.

Description

technical field [0001] The application belongs to the field of epoxy asphalt materials, in particular to an epoxy asphalt quick-drying material. Background technique [0002] Epoxy coal tar pitch anti-corrosion coating is prepared from epoxy resin, synthetic resin, coal tar pitch, pigments and fillers, solvents and additives. Low temperature curing, fast drying; excellent physical and mechanical properties, tough paint film; good water resistance and heat and humidity resistance; excellent resistance to chemical media corrosion; excellent cathodic protection matching; self-priming, bottom surface one. [0003] Epoxy asphalt has a wide range of applications, long life, weather resistance, deformation resistance, high tensile strength, high elongation, strong adaptability to base shrinkage and cracking deformation, acid resistance, alkali resistance, anti-corrosion and waterproof performance, any The complex parts are easy to construct, which solves the problems of tradition...
