Embodiment 1

[0021] [Example 1] Preparation of polyacrylate / polysilane core-shell composite emulsion

[0022] 1. Synthesis of silanes containing styrenesulfonyltrimethoxysilyl sulfide comonomer

[0023] Silanes containing styrenesulfonyltrimethoxysilyl propyl sulfide comonomer were synthesized as follows:

[0024]

[0025] 2. Preparation of Core-Shell Polymerized Emulsion

[0026] 2.1 Monomer pre-emulsification

[0027] Mix a certain amount of deionized water and emulsifier, stir quickly to dissolve it, add butyl acrylate, methyl methacrylate, and silane containing styrenesulfonyl trimethoxysilyl propyl sulfide comonomer in turn, at 40 Stir at ℃ for 15 min to obtain a pre-emulsion.

[0028] 2.2 Semi-continuous dropwise addition

[0029] A four-neck flask equipped with an electric stirrer, a reflux condenser and a thermometer was placed in a constant temperature water bath, and the 15% pre-emulsion and APS initiator solution were stirred rapidly and gradually heated to 80° C. to obta...

Embodiment 2

[0030] [Example 2] Preparation of water-based traffic line marking paint

[0031] The formula of the water-based traffic line marking paint in this embodiment is: 8% rutile titanium dioxide, 30% core-shell polymer emulsion, 2% diethylenetriamine, 10% talcum powder, 10% barium sulfate, 15% kaolin, polyacrylic acid Sodium salt 1.5%, foam breaking polymer and polysiloxane solution 0.5%, triethylamine 2%, methanol 1%, bactericide 0.4%, nano silicon dioxide 1%, glass microspheres 5%, propylene glycol 2%, Deionized water was added to 100%.

Abstract

The invention relates to a water-based traffic mark paint, which comprises the following components by mass fraction: 8-12% of pigment, 15-30% of a core-shell polymerization emulsion, 2-10% of diethylenetriamine, 10-20% of talcum powder, 10-20% of barium sulfate, 5-25% of kaolin, 1.5-3.5% of a dispersant, 0.5-1.1% of a defoaming agent, 2-4% of triethylamine, 1-3% of methanol, 0.4-0.9% of a bactericide, 1-4% of nano-silica, 5-10% of glass beads, 2%-5% of an antifreezing agent, and the balance deionized water. The water-based traffic mark paint prepared by the method provided by the invention enhances the thickness and ultraviolet resistant ability of the coating, can be applied to construction under the condition of large air humidity, and has fast drying speed.

Description

technical field [0001] The invention relates to the field of paint compositions, and specifically discloses a water-based traffic line marking paint and a preparation method thereof. Background technique [0002] Road traffic markings are all kinds of lines, arrows, text marks, etc. drawn on the road surface, which have guiding or warning settings, effectively guide traffic and disperse traffic flow, and convey basic road information to vehicles and pedestrians. At present, the common road traffic marking paints are solvent-based, hot-melt and water-based. Solvent-based road marking paints mostly use chlorinated rubber, epoxy resin and acrylic resin as film-forming substances, which often require a large amount of organic solvents, and the release of organic solvents will cause environmental pollution. Hot-melt road markings generally use petroleum resins, natural resins, etc. as film-forming substances. They are powder-like substances at room temperature. They are heated t...
