Abstract
The invention discloses a kind of road signs excellent reflective film manufacturing method of retroreflective, the glass microballoon surface in the present invention after anionic surfactant treatment carries positive charge, with TiO2·nH2O band xenogenesis electric charges, during cladding, the electric charge of hollow glass micropearl institute band is substantially completely neutralized, make it have excellent antistatic behaviour, easily form the equally distributed soot layer of individual layer, fitted between the titanium dioxide granule on glass microballoon surface and gluing oxidant layer in point-like or wire, there is gap structure between interface, form air space, be conducive to retro-reflective properties, after after aluminizing, the retro-reflecting coefficient of reflective membrane is greatly improved, reflecting effect is more preferable, with good night effects of visual cognition.
Description
Technical field
The present invention relates to a kind of preparation of reflecting film material, and in particular to a kind of road signs are excellent with retroreflective
Reflective film manufacturing method.
Background technology
Reflecting material is due to preferable reflecting effect, in traffic route mark, vehicles reflecting marking, special
The field extensive uses such as operation clothes, fire symbol, railway signs, mining area mark.Its bright reflecting effect can effectively increase
The recognition capability of strong man, improves Night visibility, and significant role is served in fields such as guarantee safety.Reflecting material is rolled over height
It is core material to penetrate rate glass microballoon or prism lattice, is made using light refraction with principle of reflection；Incident light is in certain model
Interior incidence is enclosed, reflected light is returned along the opposite direction of incident light substantially, and when the direction of incident light is changing in a big way, is remained to
Keep this characteristic.
When Refractive Index of Glass Microspheres is relatively low, its retro-reflective properties is weaker, can to strengthen the reflex reflection under low-refraction
By increasing a wall in glass microballoon refracting layer to reduce the deviation between incident light and reflected light, and it is anti-from improving
Light effect.
The content of the invention
The invention provides a kind of road signs excellent reflective film manufacturing method of retroreflective, reflective membrane it is inverse
Reflectance factor is greatly improved, with good nighttime visibility.
A kind of road signs excellent reflective film manufacturing method of retroreflective, including step in detail below：
（1）The screening of glass microballoon：
Flotation is carried out to glass microballoon, rejected because some occurred during production and transportation peel off the fragments of microballons and miscellaneous
Matter, 80-95 DEG C is dried in vacuo to remove the moisture of adsorption；
（2）Surface coating processing：
According to solid-to-liquid ratio 1:Glass microballoon after cleaning is added in distilled water by 8-15 volume ratio, adds detergent alkylate sulphur
Sour sodium, ultrasonic disperse is after 25-35 minutes, is warming up to 95-100 DEG C, adds 10% NaOH solution control system pH to 2.5-3.5,
100g/L Ti (SO are slowly added dropwise using constant pressure funnel4)2Solution, the completion of dropping in 2 hours, after reacting 3-5 hours,
Room temperature is cooled to, precipitates, filter, dry；
（3）Plant pearl：
The acrylic resins of painting adhesive in PET film, after being dried through 105-120 DEG C of drying tunnel, above-mentioned glass microballoon is adhered to
In adhesive layer side, the depth that glass microballoon is absorbed in gluing oxidant layer is the 1/3-1/2 of Glass Bead Diameter；
（4）Aluminize：
Then it is put into vacuum aluminum-plating machine and is aluminized after glass microballoon is uniformly distributed with, after winding, glass microballoon is not settled
Aluminium coated is adhered in the part of adhesive.
Wherein, the step（2）The usage amount of middle neopelex is 0.5%.
Wherein, the step（2）Ti (the SO used4)2The mass ratio of solution and glass microballoon is 25:1.
Wherein, the step（2）Drying condition is to be dried 2-3 hours in 105-115 DEG C of infrared fast dryer.
Compared with prior art, the present invention has advantages below：
（1）Surface modification processing, the glass after processing are carried out to glass microballoon using anion surfactant in the present invention
Bead surface Zeta potential is raised, and surface carries positive charge, with TiO2·nH2O band xenogenesis electric charges, can effectively facilitate next step
Titanium dioxide is handled the cladding of glass microsphere, and during cladding, the electric charge of hollow glass micropearl institute band is substantially complete
It is complete to neutralize, with excellent antistatic behaviour, it is to avoid folded pearl phenomenon, the equally distributed glass microballoon of individual layer is easily formed in coating
Layer.
（2）The glass microballoon of cladding titanium dioxide is deposited in adhesive layer side, the two of glass microballoon surface in the present invention
Fitted between titan oxide particles and gluing oxidant layer in point-like or wire, there is gap structure between interface, form air space,
Because the refractive index of air is significantly less than the refractive index of glass microballoon, angle of deviation when forming reflex reflection reduces, and is conducive to reflex reflection
Characteristic, after after aluminizing, the retro-reflecting coefficient of reflective membrane is greatly improved, reflecting effect more preferably, in the photograph of night automobile lamp
Penetrate down, the reflected light of car light light is basic to be returned in automobile driver eye along close to incident ray direction, so as to produce good
Night effects of visual cognition, safety guarantee is provided for driving at night.
