Description
Technical field
The utility model relates to polaroid technical field, especially a kind of sunglasses polaroid.
Background technique
With the improvement of working condition, requirement of the people to quality of the life is also higher and higher, in sunglasses industry, because
Polarisation sunglasses have the function of light polarization, so can fall most of harmful light barrier and not influence normal nothing
The transmission of evil visible light, can protect the eyes of people and be becoming increasingly popular, polarisation sunglasses are broadly divided into according to its structure
Iodine polarizing sunglasses and dyestuff system polarisation sunglasses, it is most of to be fabricated by polaroid as material.
Polaroid can be divided into iodine polarizing piece and dyestuff system polaroid according to colouring method.Iodine polarizing piece have compared with
High transmitance and degree of polarization, but its endurance quality is poor, has biggish limitation in application aspect, to endurance quality requirement
Higher product can not be widely applied.And relatively low polarisation sunglasses industry, dyestuff system polarisation are being required degree of polarization
For piece then because of its durability height, good weatherability such as can use at the superior characteristic under severe conditions, and in polarisation sunglasses
On using upper more and more extensive, market demand is increasing.
Dye-type polaroid obtains on sunglasses product due to its good endurance quality and its color category are various
To extensive use.At present in sunglasses dye-type polaroid production field, universal manufacturing method is PVA film in two colors
Property dye liquor in upper dye, and after the processes such as stretched, fixation, drying, it is transparent that two layers to shield is pasted using bonding agent
Made by TAC film.
Because of the demand in market, sunglasses dyestuff polarisation flake products have various colors, for certain colors
Product, needs 2 kinds or 3 kinds or the mixing of 4 kinds of dyestuffs could complete the production of the color product.Because of sunglasses dyestuff system
Polaroid needs that its tone is strictly maintained to stablize, and during volume production, needs each dye in its dichroism dye liquor of strict control
The concentration of material, thus constantly each dyestuff in dichroism dye liquor must be supplemented, to maintain its concentration to stablize.
For some products for needing multi-component dyes, exist since the dye quantity used is more, and between dyestuff mutual
It influences, larger for the control difficulty of the concentration of component dye each in dye liquor, production difficulty, which is higher than, uses one-component dyestuff
The product of production.
Fig. 1 shows a kind of structure of common sunglasses dyestuff polaroid, respectively includes the first TAC layer from top to bottom
The transparent TAC layer of 1(), PVA layers of 2(dye PVA layers), the second transparent TAC layer of TAC layer 3().With the variation of the market demand, to inclined
The requirement of light sunglasses color is also more and more, so that the demand to dyestuff system polaroid color is also more and more, to Mr. Yu
The product of a little colors, it usually needs 2 kinds and the above dyestuff mixing dye liquor carry out dyeing the production for being just able to achieve the color product, right
In the product for needing a variety of dyestuff mixing dye liquors, than needing a kind of product of dyestuff difficult in production, need to solve many ask
Topic, as between each dyestuff proportion, need to monitor the problems such as concentration variation of every kind of dyestuff in process of production, be easy to appear face
Color anomaly, production difficulty is larger, and at present in process of production, in the dye liquor of multicomponent mixed dye each component it is dense
Degree, there is no accurate monitoring method, therefore the product for needing multi-component dyes, the consumption of each dyestuff in production process
Amount is difficult to accurately calculate and lead to not accurately add.This patent method can simplify product manufacturing process, reduce production difficulty, mention
Rise product colour stability.
Summary of the invention
For the dyestuff polarisation flake products of certain colors, it is necessary to can be only achieved the color using multi-component dyes color matching and want
It asks.Because in multi-component dyes dye liquor system, every kind of dyestuff has its corresponding absorption bands.The utility model provides a kind of sun
Glasses polaroid, it is intended to reduce for dye quantity required for certain products for needing multi-component dyes to dye, and then drop
Low production difficulty improves production stability.
