Description
Technical field
The present invention relates to field of polymer technology, more particularly to a kind of bloom scratch-resistant rapid shaping polyolefine material.
Background technology
Polypropylene (PP) is to develop one of plastics variety the most rapid in Plastics Industry, with mechanical property it is good,
Light specific gravity, nontoxic, easy processing, it is corrosion-resistant the advantages of, and raw material sources are wide, cheap, in household electrical appliances, automobile and packaging etc.
It is used widely in field.Current polypropylene field competition is very fierce, it is necessary to seek to reduce the mode of cost.
In household electrical appliances application field, polyolefin products especially polypropylene (PP) is applied widely, but pure PP resins are in tool
Also there is big heat-resisting not enough, dimensional contraction rate, molding cycle length in body, intensity is relatively low in applying the shortcomings of, conventional method of modifying
It is filling-modified, but the selection of filler and addition are limited, filler must targetedly be selected according to the need for material
Select, it is impossible to select more economical filler simply, addition also has particular range, otherwise can not meet the requirement of material property.
The polypropylene of high glaze has very big market potential, small household electrical appliance in field of household appliances, particularly small household appliances industry
It is many to appearance requirements such as glossiness.Meanwhile, small household electrical appliance is to contact more product in our daily lifes, is made for a long time
Necessarily it is affected with outward appearance, therefore just has higher requirement to the scraping and wiping resistance performance of material.
Small household appliances product is during injection, because the polyolefine materials such as polypropylene are all crystalline materials, in order to protect
The stability of end article compact dimensions is demonstrate,proved, molding cycle is typically longer, causes the problems such as cost is improved.
The content of the invention
The purpose of the present invention, exactly provides a kind of bloom scratch-resistant rapid shaping polyolefin to solve the above problems
Material, the characteristics of material has high gloss, scratch-resistant and short molding cycle.
To achieve the above object, technical scheme is implemented as follows：
A kind of bloom scratch-resistant rapid shaping polyolefine material of the present invention, including following components and its parts by weight：

As can be seen from the above embodiments, add when the amount of master batch is more than or equal to 50%, molding cycle can be shortened
More than 20%, cardinal principle be in master batch to add containing nucleator nucleator can rapid crystallization, also contain heat conduction in master batch
Agent, can accelerated heat loss, shortening cool time, due to the two synergy, molding cycle shortening.Because material is not required in itself
Will very high thermal conductivity therefore heat filling addition need not be a lot.Material Rockwell hardness is also obviously improved, so as to improve
The scraping and wiping resistance performance of high smooth product.
Above example is used for illustrative purposes only, rather than limitation of the present invention, about the technology people of technical field
Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent
Technical scheme should also belong to scope of the invention, should be limited by each claim.
