Description
Technical field
The present invention relates to a kind of polypropylene materials, more particularly to a kind of toothbrush handle polypropylene material and preparation method thereof.
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 is that its crowd is multiduty using pp material
It is a kind of.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.Benefit
The toothbrush handle made of general polypropylene material is more crisp, easy fracture.
Summary of the invention
The purpose of the present invention is improving the rigid-tough balance of toothbrush handle polypropylene material, a kind of toothbrush handle polypropylene material is provided
Material and preparation method thereof obtains the EP rubbers and polypropylene blend containing nanometer grade powder rubber by being blended.Realize this
The approach of one purpose is that EP rubbers elastomer and nanometer grade powder rubber is added, by the ratio for adjusting polypropylene and EP rubbers
Example is realized.
The technical solution adopted by the present invention is that:
A kind of toothbrush handle polypropylene material, the component and weight percent of the toothbrush handle polypropylene material are as follows: polypropylene
88~96%, EP rubbers 2~10%, nanometer grade powder rubber 0.1~0.5%, Masterbatch 1.5~1.9%.
The present invention is added after EP rubbers elastomer using the blend for being mainly polypropylene and EP rubbers,
It is rigid and on the weak side although meeting its toughness；By the way that nanometer grade powder rubber is added on the basis of meeting its toughness, improve
Its rigidity.Preparation in relation to nanometer grade powder rubber can be found in Chinese patent CN00816450.9.
The nanometer grade powder rubber can be following at least one: the full sulfurized natural rubber of nanometer grade powder is received
Nanoscale powder vulcanizes butadiene-styrene rubber entirely, and nanometer grade powder vulcanizes carboxylic styrene-butadiene rubber entirely, nanometer grade powder full-sulfurized nitrile rubber,
Nanometer grade powder vulcanizes carboxy nitrile rubber entirely, and nanometer grade powder vulcanizes polybutadiene rubber entirely, and nanometer grade powder vulcanizes chlorine entirely
Buna, the full sulphurated siliastic of nanometer grade powder or the full vulcanized acrylate rubber of nanometer grade powder etc..The diameter dimension of powder
It is preferred that in 20~500nm.
A kind of preparation method of toothbrush handle polypropylene material, its step are as follows:
(1) polypropylene, EP rubbers, nanometer grade powder rubber and Masterbatch are put into super mixer and is carried out uniformly
Stirring 5~15 minutes, the speed of super mixer are 500~1500 revs/min；
(2) above-mentioned gained mixture is put into injection molding machine, carries out injection molding, injection molding machine temperature is 170~220
DEG C, air-cooled 4~5 hours after taking-up, finally obtain the toothbrush handle polypropylene material.
Technical effect: toothbrush handle of the invention is added and contains due to using polypropylene and EP rubbers for primary raw material
Nanometer grade powder rubber and is added without nanometer grade powder rubber phase ratio, toothbrush so that the rigid-tough balance of product is more excellent
The inflexible target of handle will promote 10~20%, and change in toughness is little, and rigid-tough balance is more excellent, this technique is suitble to manufacture
High-end toothbrush handle product, and manufacturing process is simple.
