Abstract
The invention relates to the manufacturing field of cosmetic outer package plastic lids, in particular to a formula of a cosmetic outer package plastic lid and a preparation method thereof. The formula includes 65 5% of propene polymer (PP) T30S, 255% of PP V30G, 52% of high-density polyethylene (HDPE), and 52% of thermoplastic elastomer (TPE). The preparation process includes material mixing and feeding, mould mounting, injection molding machine heating, template locking, nozzle forwarding, injection molding, cooling and pressure maintaining, nozzle backing, mould opening and product obtaining by manipulators. According to the formula of the cosmetic outer package plastic lid and the preparation method thereof, the secondary material utilization rate can be improved, secondary materials are prevented from accumulating in abundance, the consumption of raw materials is reduced, the cost is decreased, and the formula and the preparation method are energy saving and environment friendly simultaneously. Plastic lids can meet the requirement of functional test with torque of 4 kg f.cm at the temperature of 4 DEG C after being stored for 24 hours, the fracture cannot occur at the connection position of lid bowknot bands, lid bodies are not easy to fracture due to collision during the assembling or physical distribution.
Description
Technical field
The present invention relates to cosmetic outer package plastic lid and make field, formula being specifically related to cosmetic outer package plastic lid and preparation method thereof.
Background technology
Cosmetic outer package plastic lid all in the market, all because the difference of different geographical temperature easily causes renovating the appearance fracture of dish ligament junction, and is difficult to the using function demand meeting human consumer.Existing formula: Ba Saier RP348N(91 ± 8%)+Exxon vistamaxx6202(5 ± 1%)+corresponding look mother (4 ± 0.5%), have the following disadvantages, first be Ba Saier RP348N, Exxon vistamaxx6202 is pure import starting material, unit price is high, procurement cycle is long, handle import formalities numerous and diverse, can the production program be affected, cause cost increase; Next is that this recipe requirements strictly controls two times material adding proportions, to ensure the requirement of product function performance conformance with standard, will cause the bulk deposition of expecting for two times like this, reduce two times material utilization ratios, also not energy-conserving and environment-protective simultaneously; 3rd is when lower than 4 DEG C, and the moment of torsion namely renovating dish ligament junction during low temperature region cannot meet the function test requirement of 4kgf.cm, easily produces phenomenon of rupture.
Summary of the invention
Formula that the object of this invention is to provide cosmetic outer package plastic lid and preparation method thereof, it can improve two times material rate of utilization, stop two times material bulk depositions, reduce starting material consume, reduce cost, also energy-conserving and environment-protective simultaneously, deposit 24h under the condition of 4 degrees Celsius after, can meet the function test requirement of moment of torsion 4kgf.cm, renovate butterfly ligament junction and there will not be fracture, its lid also not easily breaks because of collision when assembling or logistics transportation.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: domestic raw materials, and price is low, easily purchases, procurement cycle is short, and its formula consists of: PP T30S 65 ± 5%, PP V30G 25 ± 5%, HDPE 5 ± 2%, TPE 5 ± 2%.
Its manufacture craft is: 1, spice: according to proportioning, required raw material and formula are added spice bucket simultaneously, carry out sufficient mix and blend, the time is 3 minutes, and stirrer carries out encapsulating into bag after stopping.2, feed intake: the sacked material rice be stirred is thrown in the Special discharge mouth at injection moulding machine, or automatic suction machine is opened, feed intake according to quantity.3, mould is installed: according to the technical requirements of product mold, select corresponding injection moulding machine specification, carry out installation and debugging to mould.4, injection moulding machine heating: carry out the heating before injection moulding machine unlatching according to the process specifications of injection moulding machine.5, template is sealed: check and correction mould specification size, carries out the various actions that template is sealed.6, nozzle advances: debugging injection moulding machine nozzle, proceeds to specified location, get out the various preparation works before injection moulding.7, injection moulding: carry out technological operation (referring to processing parameter record) according to the reference record on operation code.8, cool pressurize: according to different products, carry out the refrigeration cycle pressurize of different cycles, prevent the plastic cement of melting from flowing backwards, ensure that the injection moulding of product is complete, prevent deformation of products, make in effective shaping cycle, ensure the requirement of quality product conformance with standard.9, screw retreats: the injection moulding action cycle completes, screw retreats, prepares injection moulding next time.10, die sinking: injection moulding machine template retreats, separately, die sinking action completes mold parting surface.11, product got by mechanical manipulator: mechanical manipulator carries out various action according to the program of setting, takes out product in mould and is placed on dedicated conveyer belt, take out regrinding-material simultaneously and place in recycling bin.Shooting Technique process cycle completes.
The present invention has following beneficial effect: can improve two times material rate of utilization, stop two times material bulk depositions, reduce starting material consume, reduce cost, also energy-conserving and environment-protective simultaneously, after depositing 24h, can meet the function test requirement of moment of torsion 4kgf.cm under the condition of 4 degrees Celsius, renovate butterfly ligament junction and there will not be fracture, its lid also not easily breaks because of collision when assembling or logistics transportation.
