preparation example Construction

[0027] The embodiment of the present invention further provides the preparation method of the above-mentioned polyphenylene ether composite material, comprising the following steps:

[0028] Step S01, providing raw materials:

[0029] Provide the polyphenylene ether, polystyrene, elastomer, polyolefin, silicone masterbatch, inorganic powder filler, glass fiber, graft, antioxidant according to the formula;

[0030] Step S02, mixing and extruding:

[0031] The polyphenylene ether, polystyrene, elastomer, polyolefin, silicone masterbatch, inorganic powder filler, graft, antioxidant are mixed and extruded to obtain a polyphenylene ether composite material. Glass fibers are added during the extrusion processing step.

[0032] In step S01, the polyphenylene ether, polystyrene, elastomer, polyolefin, silicone masterbatch, inorganic powder filler, glass fiber, graft, and antioxidant are the same as those described above, and will not be repeated here.

[0033] In step S02, the poly...

Embodiment 1

[0042] Add 42 parts of polyphenylene ether resin from the first loss-in-weight feeder, 28.2 parts of polystyrene from the second loss-in-weight feeder, 1 part of elastomer, 2 parts of polyolefin, 0.5 part of silicone masterbatch, 1 1 part of inorganic minerals, 5 parts of grafts, 0.2 parts of primary antioxidant and 0.1 part of secondary antioxidant are added from the third weight loss feeder after high mixing, and 20 parts of glass fiber are added from the side feeding port. Then it is plasticized, melted, extruded, drawn, cooled and pelletized by a twin-screw extruder. The pellets were dried in a blower drying oven at 120°C for 2-4 hours, and then injection molded to prepare test samples and products.

Embodiment 2

[0044] Add 36 parts of polyphenylene ether resin from the first loss-in-weight feeder, 19.2 parts of polystyrene from the second loss-in-weight feeder, 1 part of elastomer, 2 parts of polyolefin, 0.5 part of silicone masterbatch, 1 1 part of inorganic minerals, 5 parts of grafts, 0.2 parts of primary antioxidant and 0.1 part of secondary antioxidant are added from the third weight loss feeder after high mixing, and 35 parts of glass fiber are added from the side feeding port. Then it is plasticized, melted, extruded, drawn, cooled and pelletized by a twin-screw extruder. The pellets were dried in a blower drying oven at 120°C for 2-4 hours, and then injection molded to prepare test samples and products.

Abstract

The invention is applicable to the field of new materials, and provides a polyphenylether composite material, a preparation method and application thereof. The polyphenylether composite material provided by the invention is specifically used for an impeller or guide blades of a hot water pump. Usually, the maximum temperature in the hot water pump can be up to 150-170 DEG C, so that the impeller and guide blades thereof are commonly formed by metal processing; and buckling deformation can exist ordinarily in case of a general high molecular resin alloy material, followed by damage caused by a large amount of friction occurring between the impeller and the inside of a motor or even the breakdown of the whole water treatment system. According to the polyphenylether composite material provided by the invention, through the coordination and combination of being used with polyphenylether, polyethylene, elastomer, polyolefin, silicone master batches and the like, and under the reinforcement action of special glass fibers, the polyphenylether composite material has superhigh physical and mechanical properties; and the high-temperature buckling resistance of the polyphenylether composite material product can be obviously improved. Thus, the invention can be applicable to an impeller or guide blades of a hot water pump.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a polyphenylene ether composite material, its preparation method and application. Background technique [0002] Polyphenylene ether resin has many excellent properties, such as mechanical properties, heat resistance, dimensional stability, self-flammability, etc., and its alloys are widely used in electronic appliances, auto parts, communication photovoltaics, water treatment and other fields. In recent years, more and more polyphenylene ether alloy materials are used in the field of water treatment. In the cold water treatment industry, polyphenylene ether resin alloy is used as the material of the impeller and guide vane of the pump body, and the heat resistance of 120-140 ° C is sufficient. ; But in the field of hot water treatment, especially when encountering some abnormal uses of water treatment, for example, one or two valves of the water inlet or outlet of the wat...
