The bottle cap body and the fixed sleeve are in once-forming by adding waste and old high-density polyethylene, low-density polyethylene secondary material, filling agents and calcium powder to waste and old polypropylene secondary material, mixing, heating and evenly stirring in a mould. The bottle cap provided by the present invention has the characteristics of low production cost, convenient installation and opening and simple preparation technology.
Description
Technical field
The invention belongs to the container seal technical field, relate in particular to a kind of bottle cap and preparation method thereof.
Background technology
Current, the bottle cap of a variety of bottles or beverage bottle is fixed as one the fixed cover of body of the bottle lid and its underpart in manufacturing process.When needs are opened bottle, with the body of the bottle lid rotation, make it to separate, thereby the junction of destruction body of the bottle lid and fixed cover can not reuse, and reaches false proof purpose with fixed cover.This bottle cap mostly adopts the manufacturing of ABS (acrylonitrile-butadiene-styrene) plastics, makes manufacturing cost very high (16000 yuan/ton).
Summary of the invention
First purpose of the present invention provides the low bottle cap of a kind of cost.
Second purpose of the present invention provides a kind of method for preparing above-mentioned bottle cap.
Realize that first purpose of the present invention provides the technical scheme of the low bottle cap of a kind of cost to be: a kind of bottle cap, comprise body of the bottle lid and fixed cover that one-shot forming is connected as one by broach, and the two inwall axially has the some raised lines that play the reinforced rib effect, body of the bottle lid and fixed cover junction are equipped with the collar, and described body of the bottle lid and fixed cover comprise the raw MAT'L of following weight parts:
Polypropylene 60--80 weight portion
High density polyethylene (HDPE) 5--20 weight portion
Low density polyethylene (LDPE) 10--30 weight portion
Extending agent 90--120 weight portion
--described polypropylene is the waste and old polypropylene reworked material;
--described high density polyethylene (HDPE) is waste and old high density polyethylene (HDPE) reworked material;
--described low density polyethylene (LDPE) is the low density polyethylene (LDPE) reworked material.
Realize that the method that second purpose of the present invention provides a kind of technology simply to prepare bottle cap may further comprise the steps:
The first step takes by weighing raw MAT'L polypropylene, high density polyethylene (HDPE), low density polyethylene (LDPE), extending agent, anti-piping compound, calcium powder, and is standby;
Polypropylene, high density polyethylene (HDPE), low density polyethylene (LDPE), extending agent, anti-piping compound, the calcium powder of second step with described weight proportion stirs;
The 3rd step added the injection machine mould molding with the raw MAT'L that stirs;
The 4th step cut out body of the bottle lid and fixed cover with the bottleneck cutting knife;
The 5th step was installed the collar at body of the bottle lid and fixed cover junction;
Heating of the 6th step and compacting are connected as a single entity body of the bottle lid, fixed cover and the collar;
The 7th step packing.
In addition: the method that described heating and compacting bottle cap are connected as a single entity body of the bottle lid, fixed cover and the collar adopts the super sonic compacting.
A kind of bottle cap provided by the present invention and preparation technology thereof are compared with prior art, because two defective materials that polypropylene, high density polyethylene (HDPE) and the low density polyethylene (LDPE) of employing regeneration promptly are commonly called as are as the raw MAT'L of producing bottle cap, thereby greatly reduce productive costs (being roughly equal to 5000 yuan/ton), and production technology is simpler.
Description of drawings
Accompanying drawing is the structural representation of a kind of bottle cap of the present invention.
The specific embodiment
Structure and preparation method to a kind of bottle cap of the present invention is described further below in conjunction with drawings and Examples.
As shown in the figure, the structure of a kind of bottle cap of the present invention comprises body of the bottle lid 1, fixed cover 2, and body of the bottle lid 1 is equipped with the collar 3 with fixed cover 2 junctions, and body of the bottle lid 1 axially has some raised lines 4 with the inwall of fixed cover 2.
Prepare a kind of bottle cap embodiment provided by the present invention:
Embodiment 1
The first step takes by weighing is respectively pulverized by waste and old polypropylene, waste and old high density polyethylene (HDPE) and waste and old low density polyethylene (LDPE) that 60 kilograms, 15 kilograms of the reworked materials made and 20 kilograms, french talc are done 100 kilograms of extending agents, 6 kilograms of calcium powders are standby;
Second step stirred polypropylene, high density polyethylene (HDPE), low density polyethylene (LDPE), french talc, the calcium powder Hybrid Heating of described weight proportion;
The 3rd step added the injection machine mould molding with materials mixed;
The 4th step cut out body of the bottle lid and fixed cover with the bottleneck cutting knife;
The 5th step was installed a collar that is made of plastics 3 in body of the bottle lid 1 and fixed cover 2 junctions;
The 6th step made body of the bottle lid, fixed cover and the collar be connected as a single entity with the compacting of super sonic capping machine, can produce 20000 one bottle caps;
The 7th step packing.
Take by weighing respectively and pulverize by waste and old polypropylene, waste and old high density polyethylene (HDPE) and waste and old low density polyethylene (LDPE) that 50 kilograms, 20 kilograms of the reworked materials made and 45 kilograms, calcium carbonate are done 150 kilograms of extending agents, 10 kilograms of calcium powders are standby;
Other steps are identical with embodiment 1.
Embodiment 3
Take by weighing respectively and pulverize by waste and old polypropylene, waste and old high density polyethylene (HDPE) and waste and old low density polyethylene (LDPE) that 90 kilograms, 10 kilograms of the reworked materials made and 45 kilograms, carbon black are done 80 kilograms of extending agents, 4 kilograms of calcium powders are standby;
Other steps are identical with embodiment 1.
Take by weighing respectively and pulverize by waste and old polypropylene, waste and old high density polyethylene (HDPE) and waste and old low density polyethylene (LDPE) that 70 kilograms, 5 kilograms of the reworked materials made and 50 kilograms, wood powder are done the extending agent 120 kg, 5 kilograms of calcium powders are standby;
