Abstract
A cellulose triacetate ester film which contains a cellulose acetate butyrate coating is disclosed, wherein each component according to parts by weight in the cellulose acetate butyrate coating comprises 0.1-10 parts of cellulose acetate butyrate, 20-80 parts of solvent, 5-10 parts of auxiliary solvent and 0.1-1 part of plasticizer. The prepared film according to the invention is even and transparent in the film appearance, little in contraction percentage, stable in geometrical size, which is provided with excellent composite performance with CR-39 resin and suitable for industrialized production.
Description
Technical field
The present invention relates to a kind of cellulose triacetate thin film, particularly a kind of cellulose triacetate thin film that contains cellulose acetate butyrate coat.
Background technology
Because cellulose triacetate (TAC) film has splendid physical and mechanical properties and good optical property, is widely used in the manufacturing field of glasses, still, there is the shortcoming of surface hardness difference in simple TAC film, and it in use is restricted.For make its manufacturing that can be used for ophthalmic lens, just generally need compound separately CR-39 resin or other attrition resistant macromolecular material can make eyeglass.Application number is 200410064764.3, name is called in the Chinese patent file of " compoiste film for lens " and discloses a kind of film, the plyability of this film and CR-39 resin can not satisfy user's needs, in strenuous test, cause separation between the two, come off, influenced the quality of eyeglass.In addition, the polarisation material and the CR-39 that use cellulose acetate butyrate (CAB) to make separately are compound, not only cost height and have other technical problem.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can with fine compound, the cellulose triacetate thin film that contains cellulose acetate butyrate coat of CR-39 resin eyeglass.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of cellulose triacetate thin film that contains cellulose acetate butyrate coat, each component is counted by weight in the described cellulose acetate butyrate coat:
0.1～10 part of cellulose acetate butyrate;
30～80 parts of solvents;
20～40 parts of solubility promoters;
0.1～1 part in softening agent.
The above-mentioned cellulose triacetate thin film that contains cellulose acetate butyrate coat, described solvent are one or more in acetone, butanone, methylene dichloride, the trichloromethane.
The above-mentioned cellulose triacetate thin film that contains cellulose acetate butyrate coat, described solubility promoter are one or more in methyl alcohol, ethanol, Virahol, ethyl acetate, the butylacetate.
The above-mentioned cellulose triacetate thin film that contains cellulose acetate butyrate coat, described softening agent are a kind of or its combination in dibutyl phthalate, diethyl phthalate or the phthalic acid dimethoxy ethyl ester.
Among the present invention, CAB is white cellulose acetate butyrate particle, it can be dissolved in the mixed solution of solvent and solubility promoter as film forming matter fully, be coated on the surface of cellulose triacetate thin film, can increase the hardness of cellulose triacetate thin film on the one hand, can increase the plyability between cellulose triacetate thin film and the CR-39 on the other hand, its parts by weight in coating are 0.1～10 part.
For the surface that CAB is applied to cellulose triacetate thin film forms the CAB coating, CAB need be dissolved in and form coating fluid in the solvent, suitable solvent of the present invention can be one or more in acetone, butanone, methylene dichloride or the trichloromethane, and its parts by weight can be 20～80 parts.
For CAB fully is dissolved in the solvent, also contain solubility promoter in the prescription of the present invention, suitable solubility promoter of the present invention can be one or more in methyl alcohol, ethanol, Virahol, ethyl acetate or the butylacetate, its parts by weight can be 5～10 parts.
For the snappiness that increases the CAB coating and the uniform continuity of coating, contain softening agent in the prescription provided by the invention, suitable softening agent of the present invention can be one or more in dibutyl phthalate, diethyl phthalate or the phthalic acid dimethoxy ethyl ester, and its parts by weight can be 0.1～1 part.
The invention provides the cellulose triacetate thin film that contains the CAB coating can prepare by following manner:
With the one side of CAB coating solution at cellulose triacetate thin film, dry under 80～100 ℃ condition then, taking up to obtain the cellulose triacetate thin film of the CAB of having coating provided by the invention.
Suitable coating method of the present invention can be extrusion coated, print roll coating or soak the formula coating.
Beneficial effect
The apparent homogeneous transparent of cellulose triacetate thin film that contains the CAB coating provided by the invention, shrinking percentage is little, geometrical dimension is stable, with the CR-39 resin good plyability is arranged, and is fit to suitability for industrialized production.
