Embodiment 1

[0015] Embodiment 1, solvent-free modified epoxy wear-resistant and weather-resistant coatings, including composite slurry and curing agent, the component weight percentage of the composite slurry is: AGE active diluent 5%, silicon carbide 20%, epoxy resin 30%, 10% of titanium dioxide, 0.1% of solvent-free silane defoamer, 0.1% of solvent-free silane dispersant, 0.1% of solvent-free silane leveling agent, and the balance is mica powder. The particle size of the mica powder is 10 microns. The content of aluminum is 35%; the epoxy resin is liquid with a solid content of 100%; the particle size of the silicon carbide is 10 microns. The preparation of the composite slurry is as follows: put AGE active diluent into the mixing tank, add epoxy resin at a speed of 300-500 rpm, stir for 10 minutes, add solvent-free dispersant, solvent-free defoamer, solvent-free leveling Agent, titanium dioxide, disperse at 800-1200 rpm for 30 minutes, sand mill until the fineness is less than 50 micro...

Embodiment 2

[0016] Embodiment 2, solvent-free modified epoxy wear-resistant and weather-resistant coatings, including composite slurry and curing agent, the component weight percentage of described composite slurry is: BGE active diluent 8%, silicon carbide 30%, epoxy resin 40%, 15% of titanium dioxide, 1% of solvent-free silane defoamer, 1% of solvent-free silane dispersant, 1% of solvent-free silane leveling agent, and the balance is mica powder. The content of aluminum is 32%; the epoxy resin is liquid with a solid content of 100%, and the particle size of the silicon carbide is 15 microns. The preparation of this compounding agent is identical with embodiment 1. The selection of the curing agent and the weight ratio between the composite slurry and the curing agent are the same as in Example 1.

[0017] The solvent-free modified epoxy wear-resistant and weather-resistant coating of the present invention can be used indoors or outdoors. The construction mainly includes: substrate pret...

Abstract

The invention discloses solvent-free modified epoxy wear-resistant weather-resistant paint, comprising composite slurry and a curing agent; the composite slurry is prepared from the components in percent by weight: 5-8% of active diluent, 20-30% of silicon carbon, 30-40% of epoxy resin, 10-15% of titanium white powder, 0.1-1% of defoaming agent, 0.1-1% of dispersing agent, 0.1-1% of flatting agent and the balance of mica powder; the curing agent adopts a solvent-free amino organic silicon curing agent with an amine value of 180mg of KOH / g; a weight ratio of the composite slurry to the curing agent is 2:1. The paint has the anticorrosion and chemical resistant protection functions of common epoxy paint and also has anti-ageing and wear-resistant functions, can be painted at a surface irradiated by ultraviolet, and has the characteristic of excellent weather resistance. The paint is environment-friendly, weather-resistant and wear-resistant and can meet requirements of anticorrosive and antiskid fields.

Description

technical field [0001] The invention relates to an environment-friendly solvent-free modified epoxy wear-resistant and weather-resistant coating with wear-resistant and aging-resistant functions, which can be applied in the field of industrial heavy-duty anti-corrosion and construction. Background technique [0002] Traditional epoxy coatings can protect substrates from harsh environments, but they contain solvents, are poor in environmental protection, and have poor weather resistance. They are easy to chalk after being exposed to ultraviolet light, and are not suitable for external use as topcoats. Solvent-free modified epoxy wear-resistant and weather-resistant coatings overcome the disadvantages of poor weather resistance of epoxy, can be used both internally and externally, and are truly solvent-free and environmentally friendly, making epoxy coatings suitable for applications in various occasions. Contents of the invention [0003] The technical problem to be solved ...
