Abstract
The invention discloses a method of adding excipient components into modified polyphenylether and uniformly mixing, which comprises the steps of excipient granulation, product preparation and the like. The modified polyphenylether product can reach relative component uniformity, more stable property, and easy processing.
Description
Technical field:
The present invention relates to a kind of production method of modified polyphenyl ether product.
Background technology:
Noryl is one of the world's five big general engineering plastic, has superior mechanical performance, electric durability energy, heat resistance, good dimensional stability and against weather.Be widely used in many special industries, use as High-Voltage Electrical Appliances industry, household electrical appliance, office appliance, auto parts machinery and civilian or special water supply industry etc.
Noryl is to be stock by former powder of polyphenylene oxide and polystyrene resins, phosphonium flame retardant, plasticity butadiene-styrene rubber body, antioxidant and other auxiliary agent have been added simultaneously, wherein the consumption of fire retardant, flexibilizer, antioxidant and other auxiliary agent is all below 10%, minimum has only 0.5%, even still less.In the production and processing, generally adopt weight-loss type feeder or volume feeder.Because various auxiliary materials and major ingredient be mixing (tack of material is not enough) mutually, cause compound before adding double screw extruder, to produce layering, accuracy that it is reinforced and uniformity can not get guaranteeing, so in process of production, can only adopt a plurality of weight-loss type feeders that material is joined double screw extruder simultaneously.Raw material for former powder of polyphenylene oxide and polystyrene resins can adopt independent feeder, realize evenly adding, component for other then can't be realized smoothly, the addition of these materials is all below the reinforced lower limit of weight-loss type feeder, the accuracy that adds also can't be effectively guaranteed, as mix to add and also have uneven problem, causing the inhomogeneous of properties of product, production process is also unstable.
Summary of the invention:
The object of the present invention is to provide a kind of modified polyphenyl ether product component of formation even, add the method that the auxiliary material component mixes in the Noryl of the stable performance of product.
Technical solution of the present invention is:
Add the method that the auxiliary material component mixes in a kind of Noryl, it is characterized in that: comprise the following steps:
(1) auxiliary material granulation: on double screw extruder, be carrier, use the weight-loss type feeder, add flexibilizer, antioxidant and other auxiliary agent in proportion, extrude, make the auxiliary material particle with the polystyrene; The percentage by weight of above-mentioned each component is:
Carrier 10%~80%
Antioxidant 5%~10%
Flexibilizer 10%~50%
Other auxiliary agent 5%~30%;
(2) make product: on double screw extruder, adopt different weight-loss type feeders, add the former powder of polyphenylene oxide, polystyrene resins, plasticity butadiene-styrene rubber, auxiliary material particle and fire retardant respectively, extrude the modified polyphenyl ether product; The addition of auxiliary material particle wherein: 10%~20%.
Other auxiliary agent is one or more in coloring agent, opacifier, maleic anhydride, the benzoin.
The formed modified polyphenyl ether product of the present invention can reach that relative component is even, and the performance of product is more stable, is easy to processing.
The present invention is on same double screw extruder, adopts the process that the auxiliary materials of product are carried out granulation in advance, makes that auxiliary material can disperse uniformly in the final products, and the performance of product is able to more stable.The auxiliary material granulation also can be realized on different double screw extruders with the formation of modified product.
The present invention adopts the auxiliary material process for granulating, makes that auxiliary material all remains in adition process more than 5% in the modified product, can be controlled between the upper and lower limit of weight-loss type feeder, and the charging precision of various materials all can be guaranteed.
The present invention adopts the auxiliary material process for granulating, and various auxiliary materials are uniformly dispersed in product, helps strengthening big intermolecular the moving of modified polyphenyl ether product, and the flowability of product is improved.
Adopt the material modified stable performance of this invention processing, vitrification point is hanged down and is easy to machine-shaping.
Result of the test and data analysis:
Test is carried out with mode of comparing, and the mode that adopts the inventive method to mix with an original powder compares.
Process of the present invention: be to be carrier with polystyrene resins earlier, with flexibilizer, antioxidant and other auxiliary agent in the prescription, cause in advance the auxiliary material granulation, it is reinforced that a feeder is used in high impact polystyrene (HIPS) in will filling a prescription again, plasticity butadiene-styrene rubber (SBS) and auxiliary material granulation mutually with, and former powder of remaining polyphenylene oxide and phosphorus flame retardant (TPP) are used the feeder separate charging respectively.
Grain powder mixing feed way: former powder of polyphenylene oxide and TPP use the feeder separate charging respectively, and remaining various pellet mixes feeder of employing mutually with powder and is added to.
Each test moves 2 hours respectively, gets the performance test that a sample carries out sample respectively every half an hour, and all samples all adopts identical process conditions to carry out sample preparation.
The correction data of being tested is as follows:
