The alloy comprises, by weight, 30-60 parts of PPS, 35-50 parts of PPO, 5-20 parts of silicon carbide whiskers, 2-5 parts of phenyl salicylate, 1-3 parts of light stabilizer TH-944, 5-20 parts of compatilizer, 1-2 parts of antioxidant 618, 1-2 parts of calcium-zinc stabilizer and 1-3 parts of lubricant. The silicon carbide whiskers are adopted to enhance the PPO/PPS alloy so as to enable the weather-proof enhanced PPO/PPS alloy to have excellent mechanical property and dimensional stability and to be easy to process and form; meanwhile, the phenyl salicylate and the light stabilizer TH-944 are compounded, so that the problem that PPO/PPS alloy products are prone to discoloration when under ultraviolet light for a long time can be effectively avoided.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of weather-proof enhancement type PPO/PPS Alloy And Preparation Method.
Background technology
Polyphenylene oxide, be called for short PPO, is one of the world's five large general engineering plastic.It is nontoxic, transparent, relative density is little, has that good physical strength, proof stress are lax, creep resistance, thermotolerance, water tolerance, water-fast steam and a dimensional stability; Good electrical property in very wide temperature, range of frequency, be not hydrolyzed, molding shrinkage is little, and difficult combustion has self-extinguishing, the poor performance such as inorganic acid resistance, alkali, anti-aromatic hydrocarbon, halohydrocarbon, oils, easily swelling or stress cracking, have melt fluidity poor, the shortcomings such as machine-shaping difficulty.
Polyphenylene sulfide, English is abbreviated as PPS, is a kind of novel high-performance thermoplastic resin, has that physical strength is high, high temperature resistant, an advantage such as chemical proofing, difficult combustion, Heat stability is good, electrical property are good.All be widely used at electronics, automobile, machinery and chemical field, but PPS matter is crisp, easily produces stress embrittlement, this has limited its use range greatly.
The PPO/PPS alloy combines the advantage of PPS and PPO, there is good mechanical property, electrical property, high temperature resistant, corrosion-resistant, overcome that PPS is crisp, melt viscosity is too low, the injection moulding overlap overflows not easy-formation simultaneously, and the not anti-solvent of PPO and the shortcoming such as melt viscosity is excessive; This product, except keeping the PPS high-performance, has also had that the PPO shrinking percentage is low concurrently, characteristics of product surface gloss, electrical property excellence.The research of the many relevant PPO/PPS of raising alloy properties is arranged at present, though certain effect is arranged, weathering resistance and the resistance to impact shock of PPO/PPS alloy still need to be further improved.Therefore how overcoming the deficiencies in the prior art is problems that current technical field of macromolecules is needed solution badly.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art, a kind of weather-proof enhancement type PPO/PPS Alloy And Preparation Method is provided, this alloy not only mechanical property is good, also has good weathering resistance simultaneously.
The technical solution used in the present invention is as follows:
A kind of weather-proof enhancement type PPO/PPS alloy, comprise 30 ~ 60 parts of the following raw material according to the parts by weight meter: PPS, 35 ~ 50 parts of PPO, 5 ~ 20 parts of silicon carbide whiskers, 2 ~ 5 parts of salicylic acid phenyl esters, 1 ~ 3 part of photostabilizer TH-944,5 ~ 20 parts of compatilizers, 1 ~ 2 part of antioxidant 618,1 ~ 2 part of calcium zinc stabilizer, 1 ~ 3 part of lubricant.
Further, its preferred version is that described compatilizer is epoxy resin.
Further, its preferred version is that described lubricant is stearate.
The present invention also provides a kind of preparation method of weather-proof enhancement type PPO/PPS alloy, the method is that PPS, PPO, silicon carbide whisker, salicylic acid phenyl ester, photostabilizer TH-944, compatilizer, antioxidant 618, calcium zinc stabilizer and lubricant are joined in high-speed mixer, mix by the twin screw extruder extruding pelletization, obtain weather-proof enhancement type PPO/PPS alloy, extrusion temperature is 280 ~ 330 ℃.
Compared with prior art, its beneficial effect is in the present invention:(1) the present invention adopts silicon carbide whisker to be strengthened the PPO/PPS alloy, makes product of the present invention have good mechanical property and dimensional stability, easily machine-shaping; (2) composite with salicylic acid phenyl ester and photostabilizer TH-944, can effectively avoid PPO/PPS alloy product allochroic problem under ultraviolet ray for a long time; (3) preparation method of the present invention is simple, is easy to promote.
