Abstract
The invention discloses a high-temperature-resisting injection molding material. The high-temperature-resisting injection molding material is prepared from, by mass, 60-80 parts of PVC resin, 30-40 parts of polycarbonate, 8-12 parts of plasticizer, 4-6 parts of lubricant and 8-22 parts of heat stabilizer, wherein the heat stabilizer is prepared from, by mass, 31-35% of zinc stearate, 41-49% of calcium carbonate and the balance hydrotalcite in a mixed mode. In this way, the material has high high-temperature-resisting performance, and the service life of the material at the high-temperature environment is prolonged.
Description
Technical field
The present invention relates to a kind of injected plastics material, particularly to a kind of high temperature resistant injected plastics material.
Background technology
So-called injection mo(u)lding refers to inject in mould by the injection of material adding heat fusing, cooled is become after solidifying
The method of type product, its detailed process is: send into the barrel of heating by granular or powdered plastic from the hopper of injection machine, heated
Plastify into molten condition, then press and injected by nozzle in the mold cavity of Guan Bi, keep die cavity institute by hardening by cooling
The shape given, die sinking takes out after colloid, and the injected plastics material of present stage there is also following defect during use:
Resistance to elevated temperatures is poor, causes easy deliquescing under the use environment that temperature is higher, thus affects it and use quality.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of high temperature resistant injected plastics material, it is possible to possesses and has stronger resistance to height
Warm nature energy, thus improve service life in high temperature environments.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of high temperature resistant injected plastics material,
Composition including following mass fraction:
Polyvinyl chloride resin 60-80 part；
Merlon 30-40 part；
Plasticizer 8-12 part；
Lubricant 4-6 part；
Heat stabilizer 8-22 part；
Wherein, described heat stabilizer is made up of zinc stearate, calcium carbonate and brucite mixing, calculates according to mass percent, institute
The content stating zinc stearate accounts for 31-35%, and the content of described calcium carbonate is 41-49%, and surplus is brucite.
In a preferred embodiment of the present invention, the content ratio of described plasticizer and described lubricant is 2:1.
In a preferred embodiment of the present invention, described plasticizer be phthalate, aliphatic dibasic acid ester,
Any one or more mixing of phosphoric acid ester.
In a preferred embodiment of the present invention, described lubricant is any one or more of silicone oil, fatty acid, polyester
Mixing.
The invention has the beneficial effects as follows: a kind of high temperature resistant injected plastics material of the present invention possesses and has stronger resistance to elevated temperatures, from
And improve service life in high temperature environments.
Detailed description of the invention

Described lubricant is any one or more mixing of silicone oil, fatty acid, polyester.
The preparation method of a kind of high temperature resistant injected plastics material of the present invention is as follows:
(1), according to aforementioned proportion weigh polyvinyl chloride resin, Merlon, plasticizer, lubricant, carry out in being put into high-temperature smelting pot
High temperature merges, and obtains mixed liquor,
(2), according to aforementioned proportion zinc stearate, calcium carbonate and brucite carried out proportioning, and stirs in being put into blender
Uniformly, heat stabilizer is obtained；
(3), above-mentioned heat stabilizer is gradually put into above-mentioned mixed liquor, subsequently by screw extruder extrusion molding, finally
Obtain high temperature resistant injected plastics material.
Being different from prior art, a kind of high temperature resistant injected plastics material of the present invention is by adding heat stabilizer, and optimizes each composition
Between proportioning such that it is able to possess and have stronger resistance to elevated temperatures, thus improve service life in high temperature environments.
