Abstract
The invention relates to a preparation method of a filmed rubber stopper. The preparation method is characterized by comprising the following steps of: (1) extruding a sheet; (2) stamping the sheet: putting the suitable-thickness rubber sheet extruded in the step (1) on a film, pressing and putting the rubber sheet with the pressed film on a plunger film to be plunged into a round filmed rubber wafer, wherein the film can not be separated from the rubber wafer; (3) vulcanizing: putting the round filmed wafer made in the step (2) in a die cavity of the die while the film is arranged below, and then, arranging a layer of rubber above the round filmed rubber wafer according to the weight of a rubber stopper and vulcanizing to make a filmed rubber stopper sheet; and (4) post-processing. The method of the invention has simple process and reduced links without secondary vulcanization, can reduce rubber waste, save labor and decrease energy consumption in one aspect and can avoid damaging the film and prevent the film from aging in other aspect by being once in a high temperature to improve the product quality and ensure the drug safety.
Description
(1) technical field
The present invention relates to a kind of overlay film plug, especially relate to a kind of preparation method of overlay film plug.Belong to pharmaceutical pack material technology field.
(2) background technology
Before the present invention makes, the preparation technology of overlay film plug was the film single-sided lamination upper film that will extrude in the past, then through a sulfurizing mould sulfuration of foot, again through die-cut, cleaning, become foot to be covered with the semi-finished product of film, the semi-finished product that again foot are covered with film are tucked in the post forming sulfurizing mould, place sizing material above and carry out post-cure, and the film after the sulfuration makes through die-cut, cleaning.It mainly has the following disadvantages:
One, complex process, production link is many, for this special industry of cartridge bag material, too much production link, the probability of increase contamination of products causes bigger influence to drug safety;
Two, the sizing material waste is many, and is big to this non-renewable resources consumption of rubber, and increases production cost;
Three, film will pass through secondary high temperature, causes the damage of film, makes film aging easily, reduces its shielding properties and service life, thereby influences packaged drug quality;
Four, because of production link is many, use is artificial many, causes personnel's waste; And control of product quality difficulty;
Five, need are high temperature vulcanized through twice, the energy consumption height.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of damage that can avoid film is provided, ensures drug safety, saves the preparation method of the overlay film plug of cost.
The object of the present invention is achieved like this: a kind of preparation method of overlay film plug is characterized in that described method comprises following processing step:
Adopt extruder that the sizing material that mixes is extruded, and be cut into sheet rubber;
The sheet rubber that the thickness that step 1 is extruded is suitable is placed on the film, and pressing has pressing the sheet rubber of film to be placed on together again and is washed into blocks of circular overlay film rubber disk on the punch die, notices that film and rubber disk can not break away from;
Step 3, sulfuration
The circular overlay film rubber disk that step 2 is made is placed in the die cavity of mould, notes film below, and then puts one deck rubber according to plug weight above described circular overlay film rubber disk, vulcanizes again, promptly makes the laminated adhesive patch;
Step 4, post processing
With the laminated adhesive patch that step 3 vulcanizates, carry out die-cut, clean, promptly get the overlay film plug after the packing.
The invention has the beneficial effects as follows:
One, technology is simple, only needs once sulfuration, for this special industry of cartridge bag material, and less production link, i.e. the probability of less prod pollution guarantees that medicine is safe in utilization;
Two, the remaining sizing material of sulfuration preshoot circle of contact shape overlay film rubber disk can also have been saved non-renewable resources to greatest extent with utilizing again, reduces production costs simultaneously;
Three, sulfidization molding of film and plug, the damage that does not have secondary high temperature to cause can not cause film wear out its advantages of good shielding performance, long service life, thereby guarantee packaged drug quality;
Four, because of production link reduces, less recruitment cost, and product quality is easy to control;
Five, only need a sulfidization molding, energy consumption is low.
Compare with plug coating technique in the past, the inventive method technology is simple, and link reduces, and need not vulcanize twice, can reduce the sizing material waste on the one hand, reduces manually, cuts down the consumption of energy; The opposing party's facial mask only needs can avoid the damage of film through a high temperature, makes film be not easy to wear out, and improves the quality of products, and ensures drug safety.
(4) description of drawings
The finished product plug structural representation that Fig. 1 makes for the present invention.
Among the figure:
Rubber plug body 1, film 2.
(5) specific embodiment
The preparation method of a kind of overlay film plug that the present invention relates to is characterized in that described method comprises following processing step:
Adopt extruder that the sizing material that mixes is extruded, and be cut into sheet rubber;
The sheet rubber that the thickness that step 1 is extruded is suitable is placed on the film, flattens, and pressing is had the sheet rubber of film to be placed on together again and is washed into blocks of circular overlay film rubber disk on the sizeable punch die, notices that film and rubber disk can not break away from;
Step 3, sulfuration
The circular overlay film rubber disk that step 2 is made is placed in the die cavity of mould, notes film below, and then puts one deck rubber according to plug weight above described circular overlay film rubber disk, vulcanizes again, promptly makes the laminated adhesive patch;
Step 4, post processing
With the laminated adhesive patch that step 3 vulcanizates, carry out die-cut, clean, promptly get the overlay film plug after the packing, referring to Fig. 1.
Compare with old peritonaeum technology, this new technology is simple, and link reduces.Need not vulcanize twice.Reduce the sizing material waste.Reduce manually, cut down the consumption of energy, increase output.Topmost original old technology will be through twice sulfuration, and film will wear out easily through twice high temperature, influences product quality.The present invention is because of only vulcanizing the damage of once just avoiding film.
Claims (1)
1. the preparation method of an overlay film plug is characterized in that described method comprises following processing step:
Step 1, crowded sheet
Adopt extruder that the sizing material that mixes is extruded, and be cut into sheet rubber;
Step 2, punching
The sheet rubber that the thickness that step 1 is extruded is suitable is placed on the film, and pressing has pressing the sheet rubber of film to be placed on together again and is washed into blocks of circular overlay film rubber disk on the punch die, notices that film and rubber disk can not break away from;
Step 3, sulfuration
The circular overlay film rubber disk that step 2 is made is placed in the die cavity of mould, notes film below, and then puts one deck rubber according to plug weight above described circular overlay film rubber disk, vulcanizes again, promptly makes the laminated adhesive patch;
