Abstract
The invention discloses an improved TPR (Thermoplastic Rubber) formula and the improved TPR is characterized by comprising TPR, toluene diisocynate and isoprene rubber which are combined, wherein the TPR accounts for 33%-50% by mass of the improved TPR, the toluene diisocynate accounts for 10%-16% by mass of the improved TPR, and the isoprene rubber accounts for 40%-51% by mass of the improved TPR. According to the mode, the TPR is very good in elasticity and cold resistance (glass temperature being -68 DEG C) and very high in tensile strength.
Description
Technical field
The present invention relates to plastics field, particularly relate to a kind of thermoplastic elastomer.
Background technology
The abbreviation of thermoplastic elastomer (Thermoplastic Rubber-TPR), also claims thermoplastic elastomer (Thermoplastic Elastomer-TPE), is the material that one has rubber and thermoplastics characteristic concurrently.Thermoplastic elastomer has multiple possible structure, the most basic one is to have at least two polymer phases that disperse mutually, under normal use temperature, one is fluid (making the Tg-second-order transition temperature of temperature higher than it) mutually, another is solid (make temperature lower than its Tg or equal Tg) mutually, and exists and interact between two-phase.Show at normal temperatures caoutchouc elasticity, macromolecular material that again can plasticizing forming under high temperature, have be similar to rubber mechanical property and use properties, can process and reclaim by thermoplastics again, it has erected a bridge block between plastics and rubber.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of ameliorative TPR formula, can make thermoplastic elastomer have good elasticity, winter hardiness (vitrification point-68 ℃) and very high tensile strength.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of ameliorative TPR formula is provided, described a kind of ameliorative TPR is by thermoplastic elastomer, tolylene diisocyanate and polyisoprene rubber combine, wherein, described thermoplastic elastomer accounts for the 33%-50% of the mass percent of described a kind of ameliorative TPR, described tolylene diisocyanate accounts for the 10%-16% of the mass percent of described a kind of ameliorative TPR, and described polyisoprene rubber accounts for the 40%-51% of the mass percent of described a kind of ameliorative TPR.
In a preferred embodiment of the present invention, 48% of the mass percent of a kind of ameliorative TPR described in thermoplastic elastomer accounts for.
In a preferred embodiment of the present invention, 11% of the mass percent of a kind of ameliorative TPR described in described tolylene diisocyanate accounts for.
In a preferred embodiment of the present invention, 41% of the mass percent of a kind of ameliorative TPR described in described polyisoprene rubber accounts for.
The invention has the beneficial effects as follows: the present invention can make thermoplastic elastomer have good elasticity, winter hardiness (vitrification point-68 ℃) and very high tensile strength.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
A kind of ameliorative TPR formula is provided, described a kind of ameliorative TPR is by thermoplastic elastomer, tolylene diisocyanate and polyisoprene rubber combine, wherein, described thermoplastic elastomer accounts for the 33%-50% of the mass percent of described a kind of ameliorative TPR, described tolylene diisocyanate accounts for the 10%-16% of the mass percent of described a kind of ameliorative TPR, and described polyisoprene rubber accounts for the 40%-51% of the mass percent of described a kind of ameliorative TPR.
Be different from prior art.
In a preferred embodiment of the present invention, 48% of the mass percent of a kind of ameliorative TPR described in thermoplastic elastomer accounts for.
In a preferred embodiment of the present invention, 11% of the mass percent of a kind of ameliorative TPR described in described tolylene diisocyanate accounts for.
In a preferred embodiment of the present invention, 41% of the mass percent of a kind of ameliorative TPR described in described polyisoprene rubber accounts for.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
