Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a polycarbonate/polystyrene alloy and a preparation method and application thereof.
Background
Polycarbonates (PC for short) are high molecular polymers containing carbonate groups in the molecular chain, and are classified into various types, such as aliphatic, aromatic, aliphatic-aromatic, and the like, depending on the structure of the ester group. Due to the structural particularity of polycarbonate, the polycarbonate is the universal engineering plastic with the highest growth speed in five engineering plastics. Polycarbonate is a synthetic material that has begun to develop in the late fifties. The polycarbonate resin has outstanding impact resistance, creep resistance and dimensional stability, is widely applied to the fields of electronic and electric appliances, rail transit and aerospace, and has a dosage exceeding nylon in recent years, thereby jumping the leading position.
However, when the polycarbonate is applied to signal transmission equipment, the polycarbonate has the defect of high dielectric loss, and the transmission strength of signals can be affected. In order to solve the technical defects, polystyrene can be added to prepare the alloy. But the compatibility of the polystyrene material and the polycarbonate material is poor, and the problems of peeling and layering of the product and deterioration of mechanical properties exist.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned deficiencies and providing a polycarbonate/polystyrene alloy having a relatively low dielectric constant, while having the advantage of a relatively low density.
Another object of the present invention is to provide a method for preparing the polycarbonate/polystyrene alloy.
The invention is realized by the following technical scheme:
the polycarbonate/polystyrene alloy comprises the following components in parts by weight:
80 parts of polycarbonate;
8-25 parts of polystyrene;
5-25 parts of carboxylic acid ionomer;
rubber particle size distribution in polystyrene: the difference between the D (3, 2) value and the D (4,3) value is less than or equal to 0.5.
The rubber particle size distribution in polystyrene is obtained by a laser particle size analyzer test, and the smaller the difference value between the D (3, 2) value and the D (4,3) value is, the more round the rubber is.
Preferably, the weight ratio of polystyrene to carboxylic acid-based ionomer is from 3:1 to 1: 2.
the carboxylic acid group ionomer is an ethylene/methacrylic acid copolymer, wherein 40mol% -90mol% of carboxyl groups in methacrylic acid units are neutralized by metal ions, the melt index range is 0.5-15 g/10min, and the test conditions are 190 ℃ and 2.16 kg.
The metal ions are at least one of sodium ions, zinc ions, magnesium ions and potassium ions
The melt index of the polystyrene is 2-15 g/10min, and the test conditions are 200 ℃ and 5 kg.
The polycarbonate has a melt index of 3-22 g/10min, and the test conditions are 300 ℃ and 1.2 kg.
Polycarbonates, which are branched thermoplastic polymers or copolymers obtained by reacting dihydroxy compounds or dihydroxy compounds and small amounts of polyhydroxy compounds with phosgene (phosgene) or carbonic acid diesters. The polycarbonate resin can be produced by a phosgene method (interfacial polymerization method) or a melt method (transesterification method). The polycarbonate resin is also provided by subjecting a polycarbonate resin produced by a melt process to a post-treatment for adjusting the amount of terminal hydroxyl groups.
In the polycarbonate segment obtained by the phosgene method reaction, the repeating unit is formed by the reaction of bisphenol A and phosgene. In the polycarbonate segment obtained by the transesterification process, the repeating unit is formed by the reaction of diphenyl carbonate and bisphenol A.
0-2 parts of lubricant is also included according to the parts by weight.
The lubricant is at least one selected from stearate lubricant, fatty acid lubricant and stearate lubricant; the stearate lubricant is at least one selected from calcium stearate, magnesium stearate and zinc stearate; the fatty acid lubricant is at least one selected from fatty acid, fatty acid derivative and fatty acid ester; the stearate lubricant is at least one selected from glyceryl monostearate and pentaerythritol stearate.
The preparation method of the polycarbonate/polystyrene alloy comprises the steps of uniformly mixing the components according to the proportion, and then extruding and granulating the mixture by a double-screw extruder to obtain the polycarbonate composite material, wherein the temperature range of a screw is 190-250 ℃, and the rotating speed range is 180-500 r/min.
The application of the polycarbonate/polystyrene alloy is used for preparing plastic products of signal transmission electronic components.
The invention has the following beneficial effects:
according to the invention, the polystyrene parameter with a specific rubber distribution particle size is selected, and the carboxylic acid ionomer is added, so that the polycarbonate and the polystyrene can form a bicontinuous phase structure, and the structure enables the area of a phase interface formed between the polycarbonate and the polystyrene to be larger under the condition of a certain polystyrene content. Such a structure is advantageous in reducing dielectric loss and also in reducing alloy density.

From examples 1-5, it is preferred that the weight ratio of polystyrene to carboxylic acid-based ionomer is from 3:1 to 1: 2, a more stable bicontinuous phase structure can be formed in the resin matrix, and the density and the dielectric loss are further reduced.

As is clear from comparative example 1, the difference between the values of D (3, 2) and D (4,3) of the rubber particle size distribution of polystyrene is too large, and it is difficult to form a bicontinuous phase structure in the resin matrix, resulting in poor dielectric loss and density.
It is understood from comparative example 2/3 that when the compounding ratio is outside the range of the present invention, it is difficult to form a bicontinuous phase structure in the resin matrix.
