Abstract
The invention relates to a method for manufacturing a polyvinyl alcohol slow/controlled release film, in particular to a method for manufacturing a polyvinyl alcohol slow/controlled release packaging film. The method is characterized by taking partial alcoholysis polyvinyl alcohol and complete alcoholysis polyvinyl alcohol as main raw materials; adding a plasticizing agent, a surface active agent and the like, and mixing and gluing the materials at the temperature of 85-95 DEG C, wherein the solid content of the glue solution is 13-18%; and manufacturing a film through a solution salivation method. Meanwhile, the slow/controlled release function is realized by automatically producing micro pores or micro gaps in water. By using the method provided by the invention, the slow release speed of the polyvinyl alcohol slow/controlled release film can be set according to users' demands. The film has slow/controlled release property and biological degradability in water, can be used for packaging various chemical products pesticides such as washing agents, pigments, dyes, cleaning agents, water treatment agents, mineral additives and the like requiring slow/controlled release and used in water, and can also be used as a packaging film for fruit bags and the like.
Description
Technical field
The present invention relates to the thin film fabrication technology, relate in particular to a kind of Z 150PH sustained-release and controlled release film-forming method that can run into water generates micropore or micro chink.
Background technology
At present, domestic report relevant for Z 150PH micropore or micro chink slowly-releasing film product is characterized in that there is micropore in film itself, utilizes micropore to carry out bioseparation, drug release etc.The shortcoming of this micropore release membranes is itself to exist micropore to be unfavorable for packing fine powder, fluent material (like pesticide emulsion) etc.So just limit the range of application of micropore release membranes on market, especially can not satisfy the regulatable needs of some special occasions requirement slow release speeds.
Summary of the invention
The technical problem that the present invention solved is to provide a kind of Z 150PH sustained-release and controlled release film-forming method; A kind of adjusting of saying so more specifically runs into the formulation ratio method of the Z 150PH sustained-release and controlled release film slow release speed of water generates micropore or micro chink, can be used for solving the shortcoming in the above-mentioned background technology.
The technical problem that the present invention solved adopts following technical scheme to realize:
Z 150PH sustained-release and controlled release film-forming method; Be that Z 150PH with partial alcoholysis Z 150PH, complete alcoholysis is a main raw material; Add softening agent, tensio-active agent; Under 85 ℃～95 ℃ temperature, utilize reaction kettle mixing glue, glue solid content 13～18% is again through solution salivation method film.
The regulation and control of Z 150PH sustained-release and controlled release film slow release speed are to realize through the proportioning that is adjusted to partial alcoholysis Z 150PH in the film, complete alcoholysis Z 150PH; It realizes that principle is that the partial alcoholysis Z 150PH runs into dissolve behind the water and separates out generation micropore or micro chink.
In the present invention, its membrane-forming agent: complete alcoholysis type Z 150PH comprises: 10-99,13-99,17-99,18-99,19-99,20-99,24-99 etc.; Partial alcoholysis type Z 150PH comprises: 15-97,17-97,18-97,22-97,28-97,17-95,24-95,15-92,20-92,24-92,10-88,13-88,15-89,17-88,20-88,22-88,24-88,26-88,17-80,24-80 etc.
In the present invention, method comprises that membrane-forming agent set of dispense ratio, formulations prepared from solutions, drying and forming-film solidify, and is to comprise membrane-forming agent, softening agent, tensio-active agent in the solution.After salivation method became film, the weight proportion of film each component was following:
Membrane-forming agent 70%～95%; Softening agent 1%～12%; Tensio-active agent 0.5%～8%; Water 0%～16%, wherein water cut is relevant with ambient temperature and humidity, and when ambient temperature and humidity was big, water cut was big, ambient temperature and humidity hour, water cut is little.
In the present invention; The membrane-forming agent of Z 150PH sustained-release and controlled release film is complete alcoholysis type polyalkenylalcohols, two kinds of composition combinations of partial alcoholysis type Z 150PH, through regulating the different proportionings of two kinds of compositions, regulates and sets Z 150PH sustained-release and controlled release film slow release speed; Partial alcoholysis type Z 150PH ratio is big more; Running into behind the water dissolving, to separate out component many more, and it is big more to produce micropore or micro chink or micro chink, and sustained-release and controlled release film slow release speed is fast more; Softening agent is glycerine, polyoxyethylene glycol, terepthaloyl moietie or their arbitrary combination, and effect is to regulate the film flexibility; Tensio-active agent is sodium lauryl sulphate, X 2073 or their arbitrary combination, and effect is to improve film-forming process property.
Z 150PH sustained-release and controlled release film filming technology is that membrane-forming agent, softening agent and water are joined in the reaction kettle in proportion, and stirring and be heated to temperature is after 80 ℃～95 ℃ glues become glue, be cooled to 60 ℃～70 ℃ after; Add tensio-active agent in proportion, stir, process sizing material; The sizing material solid content is 13%～18%; The glue amount is utilized water-sol hydrostomia mechanism film after leaving standstill de-bubble, glue temperature is 40 ℃～60 ℃ during hydrostomia.
Method of the present invention comprises the use of stripping dissolved constituent method down of membrane-forming agent set of dispense ratio, water at low temperature (below 40 ℃); Regulate Z 150PH sustained-release and controlled release film slow release speed through the composition of regulation and control membrane-forming agent composition; In the membrane-forming agent; By water at low temperature (below 40 ℃) dissolving, partial alcoholysis type Z 150PH can not dissolved by water at low temperature (below 40 ℃) complete alcoholysis type Z 150PH fully; When increasing along with complete alcoholysis type Z 150PH proportioning, sustained-release and controlled release film slow release speed slows down, and along with partial alcoholysis type Z 150PH increases, sustained-release and controlled release film slow release speed is accelerated.Concrete proportioning ratio is according to the requirement of sustained-release and controlled release film slow release speed, and adjustment is confirmed.
In the present invention, chemical reaction does not take place between each component, glue under 85 ℃～95 ℃ temperature, each component is physical dissolution only, passes through casting machine hydrostomia film forming behind the glue.
Beneficial effect: the invention has the advantages that and to regulate release film slow release speed arbitrarily according to user's requirement, thereby can satisfy the needs of various different users.Use the present invention to set release film slow release speed arbitrarily according to customer requirements.This film has release property, biological degradability; Can be used for being used for packing the chemical products that needs release that various water such as agricultural chemicals, washing composition, pigment, dyestuff, sanitising agent, water conditioner, mineral additive use, also can be used as packing film and be used for fruit bag etc.
