Abstract
A kind of preparation method of the cosmetic bottle of high intensity provided by the invention effectively improves the high-intensity performance of material, preparation process is relatively easy by adding inorganic additive into conventional polyethylene.By the way that preferred inorganic additive to be added in PE plastics, it can not only increase plastic product volume, reduce cost, and hardness and rigidity can be improved, reduce the shrinking percentage of plastic products, improve dimensional stability；Aluminium oxide is added, ocratation, graphene is to improve the processing performance of plastics, improve its high intensity.It has a significant effect in the expansion of polyethylene application range.
Description
Technical field
The present invention relates to plastic products production field, in particular to a kind of preparation method of the cosmetic bottle of high intensity.
Background technique
With the continuous development of society, cosmetics from stage gradually enter masses, the type of cosmetics is also more next
It is more.Bottle for cosmetics is the container that gas and ambient temperature can be made to completely cut off or the container for completely cutting off external bacterium.From material
Mainly based on vial, plastics.Vial is easy to be broken.There is also many disadvantages as bottle material for plastics at present.
Polyethylene (polyethylene, abbreviation PE) is a kind of aggregated thermoplastic resin obtained of ethylene.Industrially,
It also include the copolymer of ethylene and a small amount of alpha-olefin.Polyethylene is odorless, nontoxic, feel ceraceous, has excellent resistance to low temperature
(minimum to use reachable -100 ~ -70 DEG C of temperature), chemical stability is good, is resistant to the erosion of most of soda acids (intolerant to oxidisability
The acid of matter).Common solvent is not dissolved under room temperature, water imbibition is small, and electrical insulating property is excellent.
China's polyethylene industry reaches 10,820,000 tons by device annual capacity in 2011 by continuing to develop in recent years.?
Still there is the operation of the devices such as Fushun petrochemical industry, Wuhan ethylene, Sichuan refinery, Daqing petrochemical during 12, to 12 latter stages, poly- second
Alkene production capacity is up to 16,670,000 tons.From the point of view of data in 2011, at 1015.2 ten thousand tons, apparent demand amount exists polyethylene state yield
1727.27 ten thousand tons, it may be seen that there are still more than 700 ten thousand tons of notches to have to rely on import for domestic polyethylene.Therefore, import
Product occupies the important proportion in China polyethylene market by its relatively high performance and cost advantage.But with the country
The expansion of production capacity and the diversification of 12 period olefin feedstocks, the degree of self-sufficiency of China's polyethylene will greatly improve, externally interdependent
Degree will gradually decrease.
Compared with Other Engineering plastics, the maximum disadvantage of polyethylene equally lies also in its lower high-intensity performance, therefore
The various methods for improving polyethylene high intensity are come into being.These methods include improving polyethylene polymerization degree, adding inorganic fill out
Material, copolymerization etc., wherein inorganic filler method is the most commonly used method of research since cost is relatively low.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of preparation side of the cosmetic bottle of high intensity
Method.

24 hours, centrifugation, obtained product was washed with deionized, and it is spare to be subsequently dried 12 h collection.Above-mentioned organic acid is citric acid
Or one of sodium citrate, malic acid or natrium malicum, quality are 0.15 ~ 0.4 g.Chlorate is in calcium chloride or magnesium chloride
One kind, additive amount be 0.2 ~ 0.3 g.The aluminium oxide: ocratation: the mass ratio of graphene is 1:2:1；It is added
Amount is 0.1-0.2g；Play the role of increasing intensity.Sodium hypophosphite additive amount is 20 ~ 30 mg, primarily serves the modified work in surface
With.
B. the preparation of calcium sulfate crystal whiskers B: alcoholic solution is prepared using 1000 mL volumetric flasks, 7 ~ 10 g, bis- water is added thereto
Calcium sulfate, and a small amount of magnesium sulfate is added, it is added in reaction kettle after 2 ~ 3min of ultrasound, at 120 ~ 140 DEG C after 4 ~ 8 h of reaction certainly
It is so cooled to room temperature, is collected after product is washed spare.Above-mentioned alcoholic solution is diethylene glycol, triethylene glycol, in polyethylene glycol
One kind, alcoholic solution concentration be 2 × 10−3~5×10−3 mol/L−1.Wherein the degree of polymerization is 400 ~ 800 in polyethylene glycol.Calcium sulfate
The effect of whisker is to improve product strength, while can be effectively reduced product density.The use of alcoholic solution is to improve solution
Viscosity improves whisker draw ratio to reduce whisker formation speed.Magnesium sulfate additive amount is the 5 ~ 16% of calcium sulfate quality, mainly
It is the crystallization in order to promote calcium sulfate, while whisker quality can be regulated and controled to a certain extent.
C. Blending Processes: A and B is mixed, and is blended into vinyon up to product.In Blending Processes, the matter of A and B
Amount is than being 3:1 ~ 2:1.The mass ratio of the gross mass and polyethylene of additive A and calcium sulfate crystal whiskers B is 5 ~ 15%.
A kind of preparation method of the cosmetic bottle of high intensity provided by the invention, preparation process are relatively easy.Passing through will
Preferred inorganic additive is added in PE plastics, can not only increase plastic product volume, reduce cost, and hardness can be improved
And rigidity, reduce the shrinking percentage of plastic products, improves dimensional stability；Aluminium oxide is added, ocratation, graphene is to improve modeling
The processing performance of material improves its high intensity.The astigmatism for improving the processing performance of plastics, improving its high intensity, improving plastics
Property, resistance to marring, smoothness；All to viscosity flow in the toughening effect and mixing process of notched Izod impact hit intensity etc. simultaneously
It has a significant effect.
