Abstract
The invention discloses an improved MAS (Metal-Alumina-Semiconductor) which is characterized by being formed by combining an MAS body, polyvinyl alcohol and polysulfone, wherein the MAS body accounts for 41-50wt% of the improved MAS, polyvinyl alcohol accounts for 25-31wt% of the improved MAS, and polysulfone accounts for 25-28wt% of the improved MAS. In such a way, the MAS can have the advantages of high hardness and impact strength, nontoxicity as well as good heat resistance, cold resistance and ageing resistance.
Description
Technical field
The present invention relates to plastics field, particularly relate to a kind of ameliorative MAS.
Background technology
The physical properties of polyvinyl alcohol is subject to the impact of chemical structure, alcoholysis degree, the polymerization degree.In polyvinyl alcohol molecule, exist two kinds of chemical structures, i.e. 1,3 and 1,2 ethylene glycol structure, but main structure is 1,3 ethylene glycol structure, i.e. " end to end " structure.The polymerization degree of polyvinyl alcohol is divided into the superelevation polymerization degree (molecular weight 25～300,000), high-polymerization degree (molecular weight 17-22 ten thousand), the middle polymerization degree (molecular weight 12～150,000) and low polymerization degree (2.5～3.5 ten thousand).Alcoholysis degree generally has 78%, 88%, 98% 3 kind.China PVA industry, through the development of more than 40 years, has become maximum in the world PVA producing country, has oil ethylene process, gas acetylene method and carbide acetylene method.Domestic PVA consumption 51.2 ten thousand t in 2007,2000-2007 average growth rate per annum reaches 7.2%.Affected by global financial crisis, the industry developments such as PVA downstream building, weaving seriously baffle, and domestic PVA consumption falls 4.5% on a year-on-year basis.The second half year in 2009, PVA Downstream Market took a turn for the better to some extent, and domestic PVA consumption rises 2.7% on year-on-year basis.A few years from now on, domestic PVA demand will be with speed increment more stably.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of ameliorative MAS, can make MAS have hardness and shock strength is high, the good advantage of nontoxic, heat-resisting winter hardiness ageing resistance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of ameliorative MAS is provided, it is characterized in that, described a kind of ameliorative MAS is combined by MAS body, polyvinyl alcohol and polysulfones.Wherein, described MAS body accounts for the 41%-50% of the mass percent of described a kind of ameliorative MAS, described polyvinyl alcohol accounts for the 25%-31% of the mass percent of described a kind of ameliorative MAS, and described polysulfones accounts for the 25%-28% of the mass percent of described a kind of ameliorative MAS.
In a preferred embodiment of the present invention, 49%. of the mass percent of a kind of ameliorative MAS described in described MAS body accounts for
In a preferred embodiment of the present invention, 26%. of the mass percent of a kind of ameliorative MAS described in described polyvinyl alcohol accounts for
In a preferred embodiment of the present invention, 25% of the mass percent of a kind of ameliorative MAS described in described polysulfones accounts for.
The invention has the beneficial effects as follows: a kind of ameliorative MAS that the present invention points out, can make MAS have hardness and shock strength is high, the good advantage of nontoxic, heat-resisting winter hardiness ageing resistance.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based 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.
An ameliorative MAS, is characterized in that, described a kind of ameliorative MAS is combined by MAS body, polyvinyl alcohol and polysulfones.Wherein, described MAS body accounts for the 41%-50% of the mass percent of described a kind of ameliorative MAS, described polyvinyl alcohol accounts for the 25%-31% of the mass percent of described a kind of ameliorative MAS, and described polysulfones accounts for the 25%-28% of the mass percent of described a kind of ameliorative MAS.
Be different from prior art.
Further illustrate 49%. of the mass percent of a kind of ameliorative MAS described in described MAS body accounts for
Further illustrate 26%. of the mass percent of a kind of ameliorative MAS described in described polyvinyl alcohol accounts for
Further illustrate 25% of the mass percent of a kind of ameliorative MAS described in described polysulfones accounts for.
In sum, a kind of ameliorative MAS that the present invention points out, can make MAS have hardness and shock strength is high, the good advantage of nontoxic, heat-resisting winter hardiness ageing resistance.
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.
