Abstract
A road sign paint and a preparation method thereof are provided. The paint is prepared by uniformly mixing 40-45 parts of waterborne polyurethane, 20 parts of titanium dioxide, 15 parts of barite powder, 1-2 parts of a wetting leveling agent, 0.5-1 part of a preservative, and the balance being water. The waterborne polyurethane emulsion used by the present invention has strong water resistance and abrasion resistance and good film-forming properties, and helps to greatly reduce the amount of coalescing agents. The obtained road sign paint has strong water resistance, abrasion resistance, dirt resistance and environmental protection property.
Description
Technical field
The present invention relates to a kind of marking paint and preparation method thereof, belong to chemical field.
Technical background
China's development in time history with marking paint is not long, and along with developing rapidly of China's vinylformic acid industry, the vinylformic acid marking paint has become the main flow of China's solvent-borne type from main line mark coating.China's marking paint is low gear solvent-borne type marking paint take the hot-melting type of acrylic acid or the like normal temperature solvent-borne type and C5 petroleum resin and modified rosin resin class as Two Mainstays at present.
This patent adopts aqueous polyurethane emulsion as the main component of marking paint, greatly reduced the use of organic solvent, reduced the VOC discharging, has the very strong feature of environmental protection and the production and transport cost is low, in addition, this aqueous polyurethane has very strong water tolerance, scratch resistance and bearing dirty property, can be used as a kind of good marking paint and applies.
Summary of the invention
The purpose of this invention is to provide splendid marking paint of a kind of water tolerance, wear resistance, bearing dirty property and the feature of environmental protection and preparation method thereof.
For realizing above purpose, the prescription of marking paint of the present invention is: in 100 parts, and aqueous polyurethane emulsion 40-50 part, 20 parts of titanium dioxides, 15 parts of ground barium sulfates, moistening flatting agent 1-2 part, sanitas 0.5-1 part, and the water of surplus.
Wherein the preparation process of aqueous polyurethane emulsion is: prepare performed polymer with 2,6 tolylene diisocyanates (TDI), polybutylene glyool adipate (PBA), BDO (BDO), dimethylol propionic acid (DMPA) for raw material.In reaction process, add N-Methyl pyrrolidone to reduce viscosity.Then obtain aqueous polyurethane emulsion after the neutralization reaction.
Wherein the proportioning of performed polymer is: the mol ratio of TDI and PBA, DMPA, BDO is 1.3:1-1.4:1, and BDO accounts for the 2%-3% of performed polymer quality, and DMPA accounts for the 5%-6% of performed polymer quality.
The preparation technology of marking paint of the present invention is: in container, add successively aqueous polyurethane emulsion, 20 parts of titanium dioxides, 15 parts of ground barium sulfates, moistening flatting agent 1-2 part, sanitas 0.5-1 part, and the water of surplus.After stirring, leave standstill, obtain marking paint after the filtration.
The beneficial effect that the present invention produces is, this patent adopts aqueous polyurethane emulsion as the main component of marking paint, greatly reduced the use of organic solvent, reduced the VOC discharging, have the very strong feature of environmental protection and the production and transport cost is low, in addition, this aqueous polyurethane has very strong water tolerance, scratch resistance and bearing dirty property, and can regulate easily hard section and soft section ratio, improve the mechanical property of urethane.Can be used as a kind of good marking paint applies.
