Abstract
The invention discloses a preparation method of a PVC steel plate coating rubber. The rubber comprises the components of: vinyl chloride, butyl acrylate, polyvinyl butyral, benzoyl peroxide, dioctyl phthalate, a dispersing agent, and an antioxidant. The preparation method comprises the steps that: an autoclave and a stirrer are cleaned; nitrogen gas is delivered in for testing pressure; a mixed solution, butyl acrylate, polyvinyl butyral, part of benzoyl peroxide, and the dispersing agent are sequentially added; a feeding port is tightly closed; nitrogen gas is delivered for dispelling air in the autoclave; vinyl chloride is added from a high-pressure feeding port; when feeding is finished, stirring is started; when pressure in the autoclave is reduced to 2Kg/cm<2>, rest of the benzoyl peroxide, dioctyl phthalate, and the antioxidant are added from the feeding port; the mixture is stirred for 30min, and is discharged. The method has the advantage of simple operation. The prepared product has good performance, and can be used for replacing imported rubber of a same type. A storage life is up to 1 year.
Description
Technical field
The present invention relates to the plastic cement preparing technical field, particularly relate to a kind of preparation method of PVC steel plate note plastic cement.
Background technology
Colored laminating steel plate, mainly take cold-rolled steel sheet or galvanized steel as substrate, uses advanced production technology, technique, at the colored PVC decorating film of surface recombination.Laminating surface of steel plate intensity is high, corrosion-resistant, and can directly cut and be washed into various goods, as the composite plastic steel plate door, VCD, the shell of refrigerator, air-conditioning etc.Yet the compound tackiness agent used of colored PVC decorating film and steel plate is dependence on import always, and is expensive, and haulage time is long, and production easily occasions a delay.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation method of PVC steel plate note plastic cement, can fill up the blank of the compound tackiness agent used of domestic colored PVC decorating film and steel plate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the preparation method that a kind of PVC steel plate note plastic cement is provided, it is characterized in that, composition comprises: vinylchlorid, butyl acrylate, polyvinyl butyral acetal, benzoyl peroxide, o-phthalic acid dibutyl ester, dispersion agent, oxidation inhibitor; Preparation method's step is:
Clean autoclave and agitator, pass into the nitrogen pressure testing, add successively mixed solvent, butyl acrylate, polyvinyl butyral acetal, part benzoyl peroxide, dispersion agent, cover tightly charging opening, logical nitrogen flooding is evicted air in still from, by the high-pressure charging mouth, add vinylchlorid again, finish and start stirring, drop to 2 Kg/cm to the still internal pressure
2The time, from opening for feed, drop into remaining BP, o-phthalic acid dibutyl ester, antioxidant, stir discharging after 30 minutes kinds.
In a preferred embodiment of the present invention, the input amount for the first time of benzoyl peroxide is 2/3rds of its total add-on.
In a preferred embodiment of the present invention, the proportioning that adds of described vinylchlorid and butyl acrylate is 75/25.
In a preferred embodiment of the present invention, the proportioning that adds of described o-phthalic acid dibutyl ester and mixed solvent is: 7.5～10:100.
PVC steel plate note plastic cement performance prepared by aforesaid method is as follows:
The faint yellow transparent viscous fluid of outward appearance;
Solid content 23～24%;
Density 0.96 ± 0.02g/cm
3
180 ℃ of stripping strengths > 50 N/25mm.
The invention has the beneficial effects as follows: the preparation method of a kind of PVC steel plate of the present invention note plastic cement, simple to operate, prepared product performance are better, alternative import glue of the same type, and storage period reaches 1 year.
