Abstract
The invention discloses a kind of glass microballoon electrostatic bead planting technique produced for reflective membrane, surface modification is carried out to glass microballoon using cationic surfactant in the present invention, bead surface Zeta potential is reduced, after through high voltage electrostatic field, make glass microballoon surface perseverance negatively charged, there is electrostatic repulsion between glass microballoon particle, negatively charged glass microballoon particle is deposited on adhesive layer surface under charge attraction effect, it is not susceptible to folded pearl phenomenon, form the equally distributed soot layer of individual layer, toasted drying afterwards, glass microballoon is set to be tightly distributed in reflective membrane surface, improve the regression reflecting performance of reflective membrane, improve glass microballoon utilization rate, reduce production cost.
Description
Technical field
The present invention relates to the production technical field of reflecting film material, and in particular to a kind of glass for reflective membrane production is micro-
Pearl electrostatic bead planting 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.
At present according to glass microballoon in epilamellar coating method, the process technology of reflective membrane is divided into painting pearl method, plants pearl method
And transfer method.Wherein, plant pearl method to be divided into electrostatic plant pearl method and spread pearl method, electrostatic plants pearl method and utilizes high voltage electric field, and glass is micro-
Pearl is powered to be adsorbed on fabric, and it is that glass microballoon is uniformly sprinkling upon on the fabric for scribbling adhesive to spread pearl method.
Due to glass microballoon high surface energy and surface charge, using traditional bead planting technique, glass microballoon is easily caused
In gluing oxidant layer skewness, glass microballoon is overlapping layer by layer, not only wastes glass microballoon raw material, and influence the property of reflective membrane
Energy.
The content of the invention
The invention provides a kind of glass microballoon electrostatic bead planting technique produced for reflective membrane, glass microballoon is non-overlapping existing
As surface uniformity, the retroreflecting excellent performance of reflective membrane, production cost reduction.
A kind of glass microballoon electrostatic bead planting technique produced for reflective membrane, 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 modification processing：
According to solid-to-liquid ratio 1:Glass microballoon after above-mentioned screening is added in distilled water by 8-15 volume ratio, ultrasonic disperse 25-
After 35 minutes, add cationic surfactant hexadecyltrimethylammonium chloride, add 10% NaOH solution adjust pH to
2.5-3.5, after being reacted 2-4 hours using stirring at low speed, after centrifugal filtration, is washed, dried；
（3）Electrostatic plants pearl：
Above-mentioned glass microballoon is pre-heated to 80-90 DEG C in an oven, rear average rate is added in fluidisation pearl groove, in resin membrane surface
Coating binder, using electrostatic equipment, by walking positive charge on deflector roll subband, glass microballoon is negatively charged, passes through charge adsorption
Effect makes glass microballoon stick at adhesive layer surface；
（4）Dry：
By step（3）Beads formed film baking-curing at a temperature of 100-105 DEG C by drying tunnel, glass microballoon is absorbed in the depth of gluing oxidant layer
Spend the 1/3-1/2 for Glass Bead Diameter.
Wherein, the step（2）The usage amount of cationic surfactant hexadecyltrimethylammonium chloride is 0.4-
0.8%。
Wherein, the step（2）The rotating speed of middle stirring at low speed is 15-35 revs/min.
Wherein, the step（2）Middle drying condition is to be dried 2-3 hours in 45-75 DEG C of infrared fast dryer.
Wherein, the step（3）Middle adhesive refers to allyl resin adhesive, and coating thickness is at 30-45 μm.
Compared with prior art, cationic surfactant hexadecyltrimethylammonium chloride is used in the present invention, to glass
Glass microballon carries out surface modification, the reduction of bead surface Zeta potential, after through high voltage electrostatic field, make glass microballoon surface permanent
It is negatively charged, there is electrostatic repulsion between glass microballoon particle, during pearl is planted, folded pearl phenomenon is not susceptible to, separately in electric charge
Under graviational interaction, negatively charged glass microballoon particle is deposited on adhesive layer surface, forms the equally distributed soot layer of individual layer,
The reflective membrane of exposed type is obtained, afterwards toasted drying, resin adhesive is shunk, and is tightly distributed in glass microballoon reflective
Film surface, can not only improve the regression reflecting performance of reflective membrane, and can reduce the usage amount of glass microballoon, improve glass
Microballon utilization rate, reduces production cost.
