Description
Technical field
The present invention relates to polymeric material fields, and in particular, to a kind of K resin combinations and preparation method thereof with answer
With.
Background technology
Soft toy material is usually PVC or TPV materials, can reach different intensity by adjusting its hardness.
Since plasticizer is easily precipitated in PVC, easily human body is damaged, more and more countries start limitation PVC and are used in toy production
In product.And TPV is then at high price, the production for toy does not have competitive advantage.Therefore it need to seek cheap and environmentally friendly material
Material.
K resins are a kind of styrene-butadiene copolymer of water white transparency, also known as transparent butadiene-styrene impact resin.It is general and
Speech, K resin unnotched impact strengths are very high, but it is very sensitive to notch.Its unnotched impact strength can reach 80KJ/m2With
On, but notch impact strength then only has 3KJ/m2, thus limit its use than more sensitive place to notch at some.K
The increase of resin notch impact strength, it is difficult to by directly add toughener realize, this is because the molecular weight of K resins and its point
Cloth differs greatly with toughener SBS, it is caused to be difficult to realize apparent toughening.The notch impact strength for improving K resins is ability
Domain technical problem urgently to be resolved hurrily.
Invention content
The object of the present invention is to provide a kind of soft K resin combinations of high-ductility can be used for producing toy, are made by compounding
With inorganic filler particle and toughener, improve the notch impact strength of K resin combinations.
It is a further object of the present invention to provide the preparation methods of the soft K resin combinations of the high-ductility.
The present invention is achieved through the following technical solutions foregoing invention purpose.
A kind of K resin combinations, including the following component calculated by weight：
