Abstract
A light-splitting film for windscreen of car is composed of a transparent substrate and a compact light-splitting coating prepared from transparent solid particles and adhesive through mixing. It is possible to inlay transparent solid particles in said transparent substrate. It can barrier strong projective light but allow the scattered and diffused light to pass through it.
Description
(1) technical field:
The present invention relates to a kind of film, especially for the pellicle of reflection, refraction, scattering high light.
(2) background technology:
Because driver's eyes are subjected to the stimulation of opposite vehicle light when automobile meeting, road can't be seen clearly and the traffic accident that causes happens occasionally.In order to weaken the car light high light that direct projection is come, if on car windscreen, cover one deck reflectance coating, because of this reflectance coating in reflection direct projection high light, also specular scattering light and diffused light, under the road conditions of insufficient light, make the place ahead scenery darker, all can't see road clearly daytime, and more can't see clearly night.Therefore, do not allow now to paste the dark-coloured material of this class before the windshield.
(3) summary of the invention:
Disclosed in this invention is both to have reflected and dispersed the direct projection high light, again the pellicle that can allow scattered light, diffused light normally pass through.
Pellicle of the present invention comprises the basement membrane of layer of transparent, and different is: on the described transparent basement membrane also equably with one deck by transparent solid particle and the fine and close beam split coating of making after adhesive evenly mixes.
Described transparent solid is preferably jewel, crystal, quartz, crystal glass, quartz glass, sodium iodide crystal block, sodium fluoride crystal block, corundum, jade, cryptocrystal aggregate, agate, soft glass, hard glass, simple glass; Described transparent basement membrane is formed from a resin, and resin is polyethylene kind, PP type, polystyrene, Polyvinylchloride, organic glass, engineering plastics, propylene composite material, polyamide, polycarbonate, polyesters, cellulose.
Preferably also be provided with layer protecting film on the described beam split coating.
The size of described transparent solid particle is preferably greater than 100 orders; The part by weight of described transparent solid particle and adhesive is preferably 1: 5～and 1: 30.
The invention still further relates to another kind of spectro-film, described film is the film that is inlaid with transparent solid particle in transparent basement membrane equably.
The size of above-mentioned solid particle preferably also is greater than 100 orders; The weight ratio of described solid particle and transparent basal lamina material preferably also is 1: 5～1: 30.
Above-mentioned transparent material is a resin, and described resin is polyethylene kind, PP type, polystyrene, Polyvinylchloride, organic glass, engineering plastics, propylene composite material, polyamide, polycarbonate, polyesters, cellulose; Described transparent solid is jewel, crystal, quartz, crystal glass, quartz glass, sodium iodide crystal block, sodium fluoride crystal block, corundum, jade, cryptocrystal aggregate, agate, soft glass, hard glass, simple glass, lucite, natural resin.
Owing to after this pellicle has had unsetting many ribs particle of layer of transparent or crystalline solid, penetrate, can play following several effect when high light:
(1) because the different geometric surface correlation of transparent solid particle comes high light that good reflex is arranged, a part of light is reflexed to space or other place, make the direct projection high light become scattered light.
(2) particle itself is the transparent body, is equivalent to countless many ribs lens, the direct projection high light that enters can be decomposed into seven look diffused lights.
(3) because some densities of solid particles are big, quality is hard, as the molecular core meeting and the high light quantum collision weakening light quantum ability of sodium fluoride, sodium iodide crystal.
(4) generally all density is big for the solids crystalline solid, can the filter light quantum weaken the impact of light quantum, and hinders the light quantum impact velocity, makes some be obstructed the high light reduction of speed and becomes diffused ray, and high light weakens.
(5) passed through fine and close transparent unsetting or many ribs solid particle and crystalline solid, dispersion obstruction, filtration, the impact effect of high light reached the beam split purpose, but because spectro-film itself is transparent work, diffused light can pass through normally.
(4) description of drawings:
Fig. 1 is the structural representation that is provided with the pellicle of coating.
Fig. 2 is the structural representation of the particle studded pellicle in transparent membrane of transparent solid.
(5) embodiment:
Figure 1 shows that the structural representation of the pellicle that is provided with coating, this pellicle is
On mylar basement membrane 1, be provided with one deck is mixed the back coating by polyurethane adhesive and crystal glass uniform particles extremely close beam split coating 2; In order to protect beam split coating 2, also compound layer protecting film 3 on the beam split coating 2, in this embodiment, crystal glass is 150 orders, the weight ratio of crystal glass and polyurethane adhesive is 1: 5.In the specific implementation, the thickness of basement membrane can be selected arbitrarily, generally between 10 μ m～100 μ m, as: 15 μ m, 20 μ m, 25 μ m, 30 μ m, 35 μ m, 40 μ m, 60 μ m, 70 μ m, 80 μ m, 90 μ m etc., but can influence its toughness because basement membrane 1 is too thin, and too thick its light transmission that can influence is advisable so be chosen in 20 μ m～40 μ m, is preferably about 30 μ m.The material of basement membrane 1 can be a mylar, also can be synthetic resin or natural resins such as polyethylene kind, PP type, polystyrene, Polyvinylchloride, organic glass, engineering plastics, propylene composite material, polyamide, polycarbonate, polyesters, cellulose.Adhesive can be the polyurethane adhesive, also can be other transmittancy adhesive preferably.The transparent solid particle that mixes with adhesive can be the mixing of the indefinite particle of shape, also can be the particle or the crystalline solid of many prismatics.Transparent solid can be jewel, crystal, quartz, crystal glass, quartz glass, sodium iodide crystal block, sodium fluoride crystal block, corundum, jade, cryptocrystal aggregate, agate, soft glass, hard glass or simple glass; The big I of transparent solid particle 4 is selected as required, then can reach technological requirement greater than 100 orders generally speaking.But because particle too carefully can increase the technology cost, cost is too high, and greater than the also more difficult at present suitability for industrialized production of 800 purpose particles, therefore difficult enforcement; Particle too slightly then influences the film penetrability, so grain size is typically chosen in 100 orders～800 orders, preferably is chosen in less expensive between 150 orders～250 orders.The weight of transparent solid particle and adhesive can be 1: 5～1: 30, decides because of the thickness of the beam split coating 2 that is coated with is different.When coating layer was thicker, transparent solid content can reduce, as 1: 5～1: 10; When coating layer was thin, the transparent solid granule content can rise, as 1: 20～1: 30; Its objective is and will form one deck on the surface of basic unit 1 to close transparent solid granular coating 2, its density is high more, and then beam split ability is good more; But the thick more then light transmission of beam split coating is poor more.In order to prevent that the impaired protective seam 3 of establishing, being covered on the beam split coating 2 of beam split coating from can be the opp film, also can be the film that other material is made, can certainly not want protective seam 3.
For clearly demonstrating the structure of this pellicle, introduce a kind of manufacture method of this pellicle below.
The method of making this pellicle has a lot, can be rubbing method, spraying process.
Be that example is illustrated below with the rubbing method:
Equipment: 1200 type coating machines (be provided with unwinding and rewinding mechanism, tension control system, entangle the limit device), material-compound tank, stainless steel.
Raw material: mylar one volume 100kg, fabric width 1000mm, thickness 30 μ m.
Adhesive, polyurethane adhesive 50kg
Crystal glass particle (150 order) 10kg
Operation: (1) equipment heats up in advance and reaches 100 ℃ of colloid baking temperatures.
(2) viscose glue is put into jar, the crystal glass particle is put into viscose glue, slowly stirs 5～10 minutes, stirs well as far as possible.Then glue is poured into the coating machine hopper, started the hopper agitating screw, stir automatically.
(3) mylar is put to unreeling shaft, film is untied the smooth full machine of wearing, arrive Scroll and spool, start coating machine then, start is prepared in the film tensioning.
Check at last: check that all preparations are perfect, can start shooting that beginning is opened slowly and quickened 40 meters～80 meters of per minutes gradually, check that coating is even, thickness is even, film enters the drying box oven dry, and the oven dry back is transparent, smooth, notices that rolling is smooth, and this is product.
Finished product inspection: transparent, smooth surface, naked eyes can be seen very thin crystal, observe with high magnified glass, the crystal density reaches more than 60% of area.
In addition,, can be cut into the specification that width does not wait, also can on coating, make diaphragm by compound again one deck opp according to the customer requirements specification.
Figure 2 shows that the structural representation of the particle studded pellicle in transparent membrane of transparent solid.It is the mylar 1 that contains the crystal glass particle, wherein is uniformly distributed with crystal glass particle 4, and the crystal glass particle is 150 orders, and crystal glass particle 4 is 1: 20 with the weight ratio of alcohol ester.In the specific implementation, the crystal glass particle 4 that is used for disperse light can be by jewel, crystal, quartz, crystal glass, quartz glass, sodium iodide crystal block, sodium fluoride crystal block, corundum, jade, cryptocrystal aggregate, agate, soft glass, hard glass, simple glass etc. are made, its size with implement that profit one is identical to get final product greater than 100 orders, select 100 orders～800 orders equally generally speaking, preferably be selected in and hand over economy between 100 orders～250 orders.Certainly the high more then light transmission of order number is good more, but is fine into very much higherly, because too slightly both influenced the film penetrability, influences film toughness again, so the order number can not be too low.Film is except becoming with above-mentioned polyester, also available other natural or Albertol, resin can be polyethylene kind, PP type, polystyrene, Polyvinylchloride, organic glass, engineering plastics, propylene composite material, polyamide, polycarbonate, polyesters, cellulose etc.The thickness of film can be between 10 μ m～100 μ m, as: 15 μ m, 20 μ m, 25 μ m, 30 μ m, 35 μ m, 40 μ m, 60 μ m, 70 μ m, 80 μ m, 90 μ m etc., be preferably 20 μ m～40 μ m, because too thin then toughness is not enough, cracky, too thick then both waste material influences the film penetrability again, and this example is chosen in 30 μ m.According to the difference of film thickness, the weight ratio of transparent solid particle and transparent thin-film material may be selected to be 1: 5～and 1: 30.Because the transparent solid particle very little, then spectroscopic behaviour is bad, then influences film penetrability and toughness too much, and the content of transparent solid particle is benefit to form layer of transparent solid particle overlayer as best one can, if the too much or too big high light that then sees through in space is too many; If form longitudinal overlap between particle, then influence penetrability.
For further specifying the structure of above-mentioned pellicle, will introduce a kind of manufacture method of pellicle below.
The method of making this pellicle is varied, blows ten kinds of youngsters such as method, periosteum method, extrusion molding, The tape casting, pulling method, rolling process as lower blowing method, upper blowing method, lining, but only is that example describes herein with the extrusion molding.
