Abstract

A waterborne road marking dope comprises water, filling, paint and additive. Each component has the weight fraction of: water of 100-300 shares, acrylic emulsion of 200-500 shares, silicon dioxide of 90-180 shares, mica powder of 30-60 shares, paint of 180-300 shares, surfactant of 15-60 shares, adhesive of 10-20 shares, thixotropic agent of 20-30 shares and thickener of 10-15 shares, etc. The viscosity of the dope can be adjusted by water when in construction and the pavement only requires rough clean for painting. The paint is inspected by Traffic Engineering Supervision and Testing Center of Traffic Ministry and is proved that 14 technical indexes such as viscosity, density and wear resistance all conform to requirements specified in the national industrial standard of Road Marking Paint, JT, T280- 2004.

Description

A kind of water-based road guide line coating

One, technical field

The present invention relates to a kind of coating, particularly road mark paint exactly is a kind of water-based road guide line coating.

Two, background technology

Existing road mark paint mostly is oiliness macromolecule resin class coating, requires the road surface clean and dry during construction.Service tool need be used solvent cleaning, both contaminate environment, and it is healthy to endanger the workman again, just gives it up sometimes, causes waste.

Three, summary of the invention

The present invention is directed to the defective of oil paint, aim to provide a kind of water-borne coatings, technical problem to be solved is that the sticking power and the wear resistance of coating and bituminous pavement or concrete road surface all will meet industry standard.

This coating comprises water, filler, pigment and auxiliary agent, and each component has following parts by weight:

100～300 parts of pure water

ACRYLIC EMULSION is or/and 200～500 parts of modified acrylic acid emulsions

60～100 parts in crystalline silicon dioxide powder

30～80 parts in amorphous silicon di-oxide powder

30～60 parts of mica powders

180～300 parts of pigment

15～60 parts in tensio-active agent

10～20 parts in tackiness agent

20～30 parts of thixotropic agent

10～15 parts of thickening materials

5～15 parts of mould inhibitors

1～5 part of defoamer.

In above-mentioned composition, can also add 10～50 parts of frostproofer propylene glycol to adapt to the needs of winter construction.

In above-mentioned composition, pigment is to select according to the needs of graticule color.If white line can be selected titanium dioxide or zinc white, the former strong coloring force, latter's strong covering power; If yellow graticule can be selected lead-chrome yellow or organic yellow etc., the rest may be inferred by analogy.

Tensio-active agent rises and disperses and wetting action, promptly on the one hand filler and pigment powder is uniformly dispersed in emulsion, reduces the surface tension of emulsion on the other hand, makes its equal energy spread on bituminous pavement and concrete road surface, to strengthen sticking power.Test shows that anionic and nonionic surface active agent all can use.

The effect of thixotropic agent: when coating was stirred, its viscosity can change with convenient construction.

Used water is adjusted required viscosity during this coating application, and road pavement only needs to clean a little, and drying-free is even if also can construct overcast and rainy.Service tool can wash by water, and is efficient and convenient.

Coating is managed inspection center through the Ministry of Communications traffic engineering and is detected, its viscosity, density, 14 technical indicators such as wear-resisting all meet national sector standard JT/T280-2004 " pavement marking paint " regulation (report number 2006-CA02-096A) especially wear resistance exceed 20% than the index regulation.

Four, embodiment

Be example with white line coating now, non-limiting examples is stated as down: (weight unit is kg in the example)

Get pure water 100,150,200,250,300; Get ACRYLIC EMULSION or modified acrylic acid emulsion or both are with arbitrary proportion blended mixed emulsion 200,300,400,450,500; Get crystalline silicon dioxide powder 60,70,80,90,100; Get amorphous and read silicon dioxide powder 30,50,60,70,80, get mica powder 30,45,50,55,60; Get zinc white 180,200,240,280,300; Get sodium alkyl benzene sulfonate, alkyl phosphate salt, fatty alcohol-polyoxyethylene ether, any tensio-active agent in the alkylphenol polyoxyethylene etc. or two or more arbitrary proportion blended mixed surfactant 15,30,40,50,60 are got polyacrylate(s) or poly-N one methylol Propionamides tackiness agent 10,15,20; Get thixotropic agent Texano (commercial disignation) 20,25,30, thickening material carboxymethyl cellulose or macrogol ester 10,15; Mould inhibitor Sodium Benzoate 5,10,15; Defoamer 1,3,5, frostproofer 10,30,50.

Arbitrary weight number in the above-mentioned various raw materials mixed promptly get this coating.
