Description
Technical field
The present invention relates to a kind of polypropylene materials, more particularly to a kind of Flexible toothbrush handle polypropylene material and its preparation side
Method.
Background technique
Currently, toothbrush handle in the market all uses injection molding and is made.Tooth-brush handle be preferably it is long and straight, handle
Middle section will be bent slightly up, and have certain elastic and fixed fulcrum, it is therefore desirable to which camber, selection hold function with anti-skidding fit
The toothbrush of energy is best.Toothbrush handle is usually of a straight line type with head toothbrushes, and tooth stress not only uniformly but also was convenient for erect brush, but some are special
The handle designs of special-shaped toothbrush have certain curvature.Toothbrush handle form is easy to hold.Brush handle is preferably formed with anti-skidding rubber, should hold
It holds comfortably, length is moderate, and has elasticity appropriate, and excessive strength when being brushed teeth with buffering makes toothbrush go to decontaminate with enough
The strength of power and massage gum, and can be to avoid due to strength macrolesion gum of brushing teeth.
Polypropylene is a kind of import plastic material that dosage is huge.About toothbrush handle use in injection molding pp material, make
For the product of modern crafts, polymarization method for prodcing polyacrylates is mature, technically reliable, and toothbrush handle pp material is crowd multiduty one
Kind.Toothbrush handle polypropylene dedicated material is had no currently on the market, and each producer is only screened according to the Performance Evaluation of itself.It utilizes
Toothbrush handle made of general polypropylene material is more crisp, easy fracture.
Summary of the invention
The object of the present invention is to provide a kind of Flexible toothbrush handle polypropylene materials and preparation method thereof, are led by being blended
It to be the atactic copolymerized polypropene containing calcium carbonate.The approach for realizing this purpose is the calcium carbonate that certain mesh number is added, and is passed through
The atactic copolymerized polypropene of suitable melting means is chosen to realize.
The technical solution adopted by the present invention is that:
A kind of Flexible toothbrush handle polypropylene material, the component and weight percent of the toothbrush handle polypropylene material are as follows: nothing
Advise copolymer polypropylene 50~90%, calcium carbonate 8~48%, Masterbatch 2%.
The melt index of the atactic copolymerized polypropene is 0.2~20.
The preferred precipitated calcium carbonate of the calcium carbonate, diameter dimension is in 200~2000 mesh.
A kind of preparation method of Flexible toothbrush handle polypropylene material, its step are as follows:
(1) atactic copolymerized polypropene, calcium carbonate and Masterbatch are put into progress uniform stirring 5~15 in super mixer
Minute, the speed of super mixer is 500~1500 revs/min;
(2) above-mentioned gained mixture is put into injection molding machine, carries out injection molding, injection molding machine temperature is 180~230
DEG C, air-cooled 4~5 hours after taking-up, finally obtain the toothbrush handle polypropylene material.
A kind of toothbrush handle flexible prepared by the present invention has preferable rigid-tough balance.Atactic copolymerized polypropene is recognized
To be a kind of preferable material of toughness, but its rigidity is weaker.By be added diameter dimension the calcium carbonate of 200~2000 mesh can
Preferably to solve the problems, such as this.
The utility model has the advantages that toothbrush handle of the invention is due to using the preferable atactic copolymerized polypropene of toughness for primary raw material, and
Addition contains calcium carbonate, so that the rigid-tough balance of product is more excellent.Due to using atactic copolymerized polypropene for primary raw material,
And be added and contain calcium carbonate and Masterbatch, compared with being added without calcium carbonate, the inflexible target of toothbrush handle will promote 20% or more,
And change in toughness is little, and rigid-tough balance is more excellent.This technique is suitble to manufacture toothbrush handle product flexible, and manufacturing process
Simply.
