Particles are subjected to surface dispersion treatment, 5-30 parts of surface-treated nanoparticles and 95-70 parts of carrier resin are added to an internal mixer or a double-roller open mill for mixing, and then the mixture is crushed in a crusher, and then crushed The material is put into a twin-screw extruder, extruded and granulated at a temperature of 175-220°C and a screw speed of 60-150 rpm to obtain a plastic anti-ultraviolet masterbatch.
Description
The present invention relates to the preparation method of a kind of functional plastic, belong to the preparation field of high molecular functional matrix material with masterbatch.
Along with the progress of society, the purposes of plastics more and more widely.But, plastics in use, under the irradiation of the ultraviolet ray in sunlight (wavelength is 290-400nm), the molecular chain of plastics can be degraded, and causes the outward appearance of plastics and physical and mechanical properties to descend.Therefore, the high plastics of service requirements must add anti UV agent in process of production, to suppress the photoaging of plastics, prolong the work-ing life of plastics.The anti UV agent that uses in the plastics is mainly organism at present, as salicylate class, benzophenone, triazines, organic complex compound and hindered amines, and (Shanxi chemical institute, " plastic, rubber processing aid ", chemical industry press, 1983; Wang Kezhi, Chinese plastics, Vol.12, No.3,1998,16) organic anti UV agent has shortcomings such as price height, contaminate environment.
The objective of the invention is to provide a kind of preparation method of ultraviolet-resistance masterbatch for plastics at the deficiencies in the prior art.Be characterized in this anti UV agent is mixed with surperficial dispersion treating agent, again will be mixing in Banbury mixer through inorganic anti UV agent and plastic carrier that surperficial dispersion treatment is crossed, with mixing thing fragmentation, at last broken thing is made ultraviolet-resistance masterbatch for plastics through the twin screw extruder extruding pelletization subsequently.
The objective of the invention is to realize that by following technical measures wherein said raw material portion rate is the weight fraction meter except that specified otherwise.
The preparation method of ultraviolet-resistance masterbatch for plastics:
1. the surface treatment of inorganic anti UV agent
With median size be the inorganic anti ultraviolet agent of 20-150nm and surface dispersant in 100: the ratio of 0.01-0.05 adds in the high-speed mixer, in temperature 100-200 ℃, mixes 10-60 minute, makes dispersion agent and inorganic anti ultraviolet agent homodisperse.
2. the compound preparation masterbatch of inorganic anti UV agent and carrier
To mix in Banbury mixer with vector resin 95-70 part by 5～30 parts through the inorganic anti ultraviolet agent that surperficial dispersion treatment is crossed, mixing temperature is 150～190 ℃, and mixing time is 15～25 minutes.With the compound fragmentation, then broken material is added in the twin screw extruder, in temperature 175-220 ℃, screw speed 60-150 rev/min, extruding pelletization makes ultraviolet-resistance masterbatch for plastics.
Inorganic anti ultraviolet agent is that lime carbonate, silicon-dioxide, zinc oxide and/or titanium dioxide are at least a.
Surface dispersant is that titanic acid ester, aluminic acid ester, silane coupling agent, alkyl hydrochlorate or lipid acid are at least a.
Carrier is that polyethylene wax, oxidized polyethlene wax, polyethylene, polypropylene, polystyrene and/or paraffin are at least a.
The present invention has following advantage:
1. preparation is simple, is easy to suitability for industrialized production.
2. the uvioresistant effect is good and timeliness is long.
3. this masterbatch is cheap, is easy to apply.
Embodiment
