Abstract
The polypropylene resin has components including polypropylene copolymer 60-80wt%, polypropylene homopolymer 5-20, polyolefine elastomer 5-15wt%, inorganic filler 5-28wt%, antioxidant 0.1-2wt%, light stabilizer 0.1-2wt% and antistatic agent 1-3wt%. It has excellent heat oxygen ageing resisting performance, light ageing resisting performance, and after xenon lamp radiation test for 2000 hr it has color of 3-4 grade, 70% maintained mechanical performance and surface resistance below 10E10. It is suitable for use in outdoor unit of air conditioner, beach chair, etc.
Description
The present invention relates to a kind of acrylic resin, particularly a sharp weather-resistant antistatic polypropylene resin used specially for outdoor unit of air conditioner.
Acrylic resin is one of five big resins for universal use, and the kind of modified polypropene also has the numerous species type, and purposes is also very extensive.But it is poor that polyacrylic disadvantage is a light aging resisting property, its degradation is a lot of behind the sunlight short irradiation, therefore limited it in outdoor application, particularly for wanting the long-term product of placing in the open, more to stand Exposure to Sunlight, drench with rain, the test of different weather condition such as severe cold, obviously improved the acrylic resin of weather resistance and can expand polypropylene purposes out of doors greatly.For the plastic part in the air conditioning machinery, produce to install and use in be easy to generate static and influence outward appearance, so need plastic material that certain antistatic effect is arranged again.
The object of the present invention is to provide a kind ofly to have weather-proof and antistatic property, be suitable for the weather-resistant antistatic polypropylene resin used specially for outdoor unit of air conditioner that the air-conditioner outdoor unit component use.
Purpose of the present invention can reach by following measure: a kind of weather-resistant antistatic polypropylene resin used specially for outdoor unit of air conditioner, it is characterized in that: the weight percent of component is a polypropylene copolymer 60～80%, homopolymer polypropylene 5～20%, polyolefin elastomer 5～15%, mineral filler 5～28%, oxidation inhibitor 0.1～2%, photostabilizer 0.1～2%, static inhibitor 1～3%.
Purpose of the present invention can also reach by following measure: the weight percent of component can be polypropylene copolymer 60%, homopolymer polypropylene 10%, polyolefin elastomer 10%, mineral filler 19.1%, oxidation inhibitor 0.2%, photostabilizer 0.5%, static inhibitor 0.2%.Described mineral filler can be talcum powder, lime carbonate, barium sulfate or their composition.Described polypropylene copolymer is the ethylene-propylene block copolymer of melting index between 0.8～30g/10min.Described homopolymer polypropylene is the homopolymer of melting index between 0.8～30/10min.Described polyolefin elastomer is the multipolymer of ethene and hexadiene.Described oxidation inhibitor is phenolic antioxidant 1010 and phosphoric acid ester oxidation inhibitor 168.Described photostabilizer is hindered amine light stabilizer, benzotriazole category photomask agent.Described static inhibitor is ethoxylated amine, glycerine-stearate, aliphatic alkane alcohol amide.
Even polypropylene copolymer still has favorable shock resistance at it below the second-order transition temperature, the rubber particles that is dispersed throughout in the half hitch crystalline state polypropylene matrix can form many focal point of stress initiation local deformations on the interface, prevent the fracture expansion.The second third block content is the best 12% in the copolymerization polypropylene of selecting for use.
Homopolymer polypropylene has favorable rigidity to be beneficial to the structure practicality of parts, selected homopolymer be molecular-weight average between 20～600,000, the range of molecular weight distributions broad is good.
Polyolefin elastomer is a kind ofly to be similar to rubber flexible transparence grain husk grain by what ethene and the copolymerization of long-chain monoolefine obtained, and it and polypropylene have good consistency, can further improve polyacrylic low temperature impact properties.
Inorganic kind of filling out class is a lot, comprises lime carbonate, talcum powder, barium sulfate etc., doses the part mineral filler and can make material that favorable rigidity is arranged and increase size stability in system, reduces goods and shrinks.
Oxidation inhibitor makes polypropylene that good processing stability be arranged in the course of processing, avoids color and luster, performance to change, and especially comes into force with photostabilizer is collaborative in the life-time service process, and good thermal-oxidative aging property is provided.The oxidation inhibitor kind of selecting for use comprises primary antioxidant and auxiliary anti-oxidant, and primary antioxidant can be chosen with Hinered phenols as 1010,1076 etc., and auxiliary anti-oxidant can select for use phosphorous acid esters as 168, TNPP etc.
Photostabilizer can protect polyacrylic segment not to be subjected to ultraviolet destruction, changes polyacrylic ageing resistance greatly.Photostabilizer can be selected hindered amines for use, and (944: 770: 1: 1), benzotriazole category also can select for use carbon black to do photostabilizer as 327,328 etc. for the black goods as 770,994 grades.
The effect of static inhibitor is by joining in the polymkeric substance, move to finished surface then, by with ambient air in moisture interact, form conductive layer so that electric charge disperses, prevent the accumulation of static charge.
The present invention has following advantage compared to existing technology; Having good thermo-oxidative ageing and photooxidation aging property, is 3～4 grades through 2000 hours its color grades of xenon lamp exposure experiments to light, and the mechanical property conservation rate is more than 70%, and surface resistivity is less than 10
