Abstract
The invention discloses a kind of single-layer coplanar tree coating process of sedimentation type reflective membrane, the glass microballoon surface Zeta potential in the present invention after anionic surfactant treatment is raised, and surface carries positive charge, with TiO2·nH2During O band xenogenesis electric charges, cladding, the electric charge of hollow glass micropearl institute band is substantially completely neutralized, excellent antistatic behaviour is made it have, the equally distributed soot layer of individual layer is easily formed；The glass microballoon of cladding titanium dioxide is evenly distributed in modified acrylic coating material afterwards, glass microballoon quality increase after coated processing, its sedimentation can be promoted to be formed, microballon rapid subsidence is to membrane surface, close uniform glass microbead layer is formed, the reflective function and quality of the reflective membrane of making are significantly improved.
Description
Technical field
The present invention relates to a kind of preparation of reflecting film material, and in particular to a kind of single-layer coplanar tree coating of sedimentation type reflective membrane
Technique.
Background technology
Retroreflecting material can simply be referred to as reflectorized material, and reflectorized material is mainly used in as a kind of new material
In terms of traffic sign, reflective purpose is played by backtracking by making light in respective material surface addition reflecting element；
So under light-illuminating, reflectorized material has just reached the visual effect of hundred times more eye-catching than other non-reflective materials.
Main raw material(s) used in reflectorized material includes resin, pigment, glass microballoon etc., and any the same raw material are to reflective production
The performance impact of product is all vital.Wherein, adhering resin must have good workability, splendid cementability,
For glass microballoon, then require that there is high index of refraction, high transparency, low devitrification rate, good circularity, good granularity uniformity
With antistatic behaviour and dispersiveness.
In the production technology of current reflective membrane, because glass microballoon antistatic behaviour is poor, disperse uneven, not in favor of shape
Soot layer is closely uniformly distributed into individual layer, glass microballoon is produced reunion, overlapping phenomenon, the property of reflective membrane is influenceed
Can, so as to influence product quality.
The content of the invention
The invention provides a kind of single-layer coplanar tree coating process of sedimentation type reflective membrane, make glass microballoon closely evenly distributed
On reflective membrane surface, reflecting effect is improved.
A kind of single-layer coplanar tree coating process of sedimentation type reflective membrane, including step in detail below：
（1）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 completion of the reaction, cooling
To room temperature, precipitate, filter, dry；
（2）Prepared coating liquid：
Glass microballoon after above-mentioned processing and modified acrylic coating material are pressed 1:Simultaneously high-speed stirred is uniform for 2-5 ratio mixing, stirring
Speed control is 4500-6500 revs/min, stirs 10-30 minutes, becomes uniform coating solution；
（3）Coating：
By step（2）Coating solution is spread evenly across in PET film, and its thickness is more than the diameter of glass microballoon, is dried through drying tunnel
Roasting drying process, 60-200s is stopped at a temperature of preceding 50-75 DEG C of road, and control settlement temperature is incubated 10- at 98-130 DEG C afterwards
50 minutes；
（4）After above-mentioned coating, then be coated with pressure sensitive adhesive adhesion coating releasing ply of paper be combined.
Wherein, the step（1）The usage amount of middle neopelex is 0.5%.
Wherein, the step（1）Ti (the SO used4)2The mass ratio of solution and glass microballoon is 25:1.
Wherein, the step（1）Drying condition is to be dried 2-3 hours in 105-115 DEG C of infrared fast dryer.
Wherein, the step（2）Described in modified acrylic coating material solid content control in 26-36%, viscosity control exists
150-250cP, and contain 0.5% silicone oil froth breaking levelling agent, 2% butyl acetate, 5-8% aluminium silver powder.
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 evenly distributed in modified acrylic coating material in the present invention, Ran Houjing
The coating mixed after coating is dried in drying tunnel, and dope viscosity declines under the conditions of drying tunnel temperature, and microballon rapid subsidence is arrived
Membrane surface, the glass microballoon quality increase after coated processing, can accelerate sinking speed, reduce the sedimentation time, glass is micro-
Without electrostatic attraction between pearl particle, sedimentation forms close uniform glass microbead layer, the reflective function and quality of the reflective membrane of making
Significantly improve.
