Description

Luminous paint

The invention belongs to coating and manufacturing technology thereof, particularly relate to the manufacturing of luminescent material and be used for the production of luminous paint.

The application of coating is very widely, all uses coating from all activities of production, life and people.Various traffic Pointing sign boards on highway, the line on track, walkway carry out smoothly for transportation and people and vehicle safety requisite.Particularly on motorway, the traffic Pointing sign board, the runway line can be run at high speed to vehicle and safe operation is crucial.At present, the label that uses on highway and the paint of lines on road surface do not have the characteristics of luminescence, use full up foot needs daytime, and evening, pedestrian and vehicle driver when no street lighting were difficult for seeing clearly.As label on the motorway is to make of reflectorized paint; The triangle arrow rack of highway pavement a kind of plastics commonly used is embedded on the road surface, just luminous reflectance can be returned according to last this label and plastic processing frame when car light, makes the officer can see sign and road conditions on the label, and these just all do not see when illumination is removed.Certainly the reflective plastic processing frame that imbeds on the road can influence the smooth of road surface.

The objective of the invention is to make a kind of luminescent material, make luminous paint with this luminescent material, this coating can be luminous after rayed, and can continue the quite a while.

The luminescent material that the present invention made is the crystalline structure of some metallic elements compositions of a kind of metallic sulfide and copper and his, and the expression of its main compound is:

AS∶Cux·By

Wherein AS is a metallic sulfide, and A is Zn, Sr, Ca, Cd, Mg; B is Bi, Er, Co; X and y are numeral, and wherein x is 1 * 10 ^-5～1.0; Y is 1 * 10 ^-7～0.1.The compound of this structure has can emitting characteristics under light excites.The preparation luminescent material raw materials used and the prescription be:

SrS 1～30% ZnS 40～98%

CaS 0～20% CdS 0～30%

CuSO ₄0～1% CuCl ₂0～1%

MgCl ₂0.0～10% S 0～20%

Na ₂S ₂O ₃0～30% ZnSiO ₃0～30%

Raw materials used specification is SILVER REAGENT (CP and an AR level).The making method of material is: earlier consumption is mixed and carries out the mechanical mill processing at the various raw materials 1% or more in proportion, purpose is that it is mixed fully; The raw material of 1% following consumption is dissolved in less water and is dispersed in thorough mixing in the above mixture under 10～50 ℃ gradually.The material that complete blending dispersion is good is inserted and is carried out solid state reaction 1～5h. under 900～1300 ℃.Then use rare gas element (N down earlier at 800～1200 ℃ ₂, Ar etc.) air in the replacement(metathesis)reaction stove, when air displacement feeds H after fully again ₂Or CO, 1～3h..Carry out mechanical ball milling after the cooling, making its granularity is 1～50 μ, carries out anti-aging stability at last and handle under 50～500 ℃.The luminescent material of making can be with painting, being made into luminous paint, and its raw material and prescription are:

Finished product paint 15～98%

Luminescent material 1～60%

Batching 0～30%

Wherein as paint commonly used such as phenolic aldehyde, polyester, epoxy and urethane, preparing burden is SiO for general for finished product paint ₂, CaCO ₃And solvent or diluent etc.The method for preparing luminous paint is: luminescent material and batching is following to 5～40%ZnSiO at 100～600 ℃ ₃Solution carries out coating to be handled.Finished product paint is warmed under 20～50 ℃, and adjusting viscosity with solvent or diluent is 20～200S.Get coating is good luminescent material and paint in proportion and mix and carry out mechanical dispersion and handle, grind and make wherein that the particulate granularity is 1～50 μ, adjusting viscosity with solvent or diluent at last under 20～50 ℃ is 40～150S.Utilize the adjustment of batching, the present invention is made as luminous paint surface drying time after brushing can reach 1～4min.Sticking power is not more than the GB secondary.

This coating is used for highway, motorway particularly, on the making of traffic Pointing sign board sign, the line of road surface speed, walking along the street indication line after solar radiation, just can be sent light at nightfall by day; Night is very weak as no street lamp or street lighting, and after the vehicle lamp shone, even car light is removed these labels and line can both be sent light, other automobiles, bicycle and pedestrian can both be visible, and this is very favourable for traffic safety.Luminous or a kind of low-light (level) of this coating after illumination luminous, fluorescent lifetime can reach more than 1 hour, and the color of coating approximately is white, light green, light blue etc., and this is relevant with painting color.This coating can also be used in the alert Jie's board of automobile tail, the making of the Pointing sign board sign that pavement construction Jie's board of dealing with emergencies and dangerous situations, rail vehicle and label etc. use various nights, and this all is absolutely necessary to safe driving and construction.

Characteristics of the present invention are: (1) prepares a kind of luminescent material with exclusive method, and it does not contain any radioactive substance, and the tangible characteristics of luminescence is arranged, can low-light (level) after the illumination luminous; (2) luminous paint of being made by luminescent material, paint etc. is after use, and can play the demonstration effect constantly night behind light-illuminating; (3) luminous paint brushing after drying speed is fast, and clinging power is strong, and ageing-resistant performance is good.Help traffic safety management, save energy.
