Description
Technical field
The invention belongs to technical field of polymer composite materials, and in particular to one kind exempt from spraying PC/ASA composites and its
Preparation method.
Background technology
Makrolon (PC) is one of with fastest developing speed, most widely used engineering plastics.Wherein yield maximum, purposes are most wide
It is bisphenol A polycarbonate.Bisphenol A polycarbonate has excellent impact strength, creep resistant, heat resistance and resists cold
Property, can use in -100 DEG C~140 DEG C temperature ranges, it is seen that the transmitance of light up to 90% or so, with anti-tensile higher
Intensity, bending strength, elongation and rigidity, resistance to ag(e)ing, excellent electrical properties and water absorption rate is low.PC materials are widely used in vapour
The field such as car, electric.But PC equally has the shortcomings that oil resistivity, wearability and processing characteristics be not good enough, and receive its application
To limitation.
Acrylonitrile-styrene-acrylic ester copolymer (ASA), due to instead of acrylic nitrile-butadiene from acrylic ester unit
Butadiene unit in diene-styrene copolymer (ABS), does not contain double bond in system, therefore the weatherability of material is obtained
It is greatly improved.ASA also retains simultaneously good mechanical property, heat endurance and it is easy to process the advantages of, it is adaptable to
Outdoor decoration material, sports equipment and automobile decoration piece etc..
PC resin and ASA have certain compatibility, and the two is blended, the PC/ASA composites of preparation combine PC and
The premium properties of ASA, is generally used for automobile and exempts to spray inside gadget.But automobile exempts to spray wearability, gloss of the inside gadget to material
Degree and weatherability have requirement higher.
By taking Volkswagen as an example, it is to the wearability requirement that automobile exempts to spray inside gadget：Tested through PV3.3.3 water mills,
After 20 cyclic tests, material surface gloss percent retension is that (gloss percent retension of common PC/ASA materials is less than 50-60%
20%)；Glossiness is required：Under 20 ° of test angles, glossiness >=90% (under same test angle, common PC/ASA materials
Glossiness is 75-80%)；Weatherability is required：Tested through PV1303 light shines, material tonal gradation >=4 grade (phase after 5 cycles
Under with test condition, tonal gradation≤2.5 grade of common PC/ASA materials).
The performance of common PC/ASA composites is far from meeting above-mentioned requirements, it is necessary to be carried out to PC/ASA composites
It is corresponding modified.CN 106084716A disclose a kind of weather-proof bloom and exempt from spraying PC/ASA alloy materials and preparation method thereof, although
The weather resistance of material is improve by adding weather resisting agent and antioxidant, but this document is not related to change anti-wear performance
Enter.CN 105885379A disclose a kind of scratch-resistant bloom and exempt from spraying PC/ASA alloy materials and preparation method thereof, the PC/ASA
Alloy material is counted by weight, by 50-70 parts of PC resin, 10-40 parts of ASA resin, 5-20 parts of scratch resistance liniment, 0.1-1 parts of phase
Hold agent, 0.1-1 parts of antioxidant, 0.1-1 parts of lubricant and 2-5 parts of black masterbatch composition.In order to obtain enough scraping and wiping resistance performances,
The scratch resistance liniments such as substantial amounts of polymethyl methacrylate (PMMA) are with the addition of in the PC/ASA alloy materials.But scratch resistance liniment and base
The compatibility of body material is poor, its while scraping and wiping resistance performance is improved, also have to the mechanical performance of PC/ASA alloy materials compared with
Big negative effect.
Therefore, expect to obtain a kind of having exempting from for good anti-wear performance, mechanical performance and higher gloss degree concurrently in this area
