Description
Technical field
The invention belongs to exempt from paint field of material technology more particularly to it is a kind of with metallic luster exempt from paint material and its
Preparation method and exempt from paint wire rod.
Background technique
Exempting from spray painting material is that the metal with different display effects is added by way of melt blending in plastic material
Powder, pearl powder, ceramic powder, bloom toner etc. make its included particular color effect.Exempt from paint material have bloom or dumb light pool,
The advantage of environmentally protective (avoiding the pollution sprayed to environment), save the cost (process is simple, and yields is high) etc..With spray
It applies plastics to compare, although exempting from painted plastic more expensive than general plastics 10%, counts paint expense etc. in, moulded using spraying is exempted from
The cost of material has dropped 20% to 30% instead.
In the prior art, usually make plastic material that there is bloom by the way that the inorganic Pearlescent powders such as pearl mica powder are added
Pool.For example, application No. is a kind of high glaze of 201310372789.9 patented invention, exempt from spray painting, scratch-resistant ABS/PMMA
Alloy material by increasing the compatibility of ABS and PMMA using ethyl methacrylate (EMA), and passes through pearl mica powder, resistance to
Liniment and barium sulfate are scraped to increase hardness and glossiness, ABS, PMMA and related auxiliaries are passed through into double screw extruder blending extrusion
It obtains, which had both remained the good processability of ABS and toughness, while it is excellent to have both the excellent weatherability of PMMA, glossiness etc.
Point realizes the high glaze of household appliance shell, exempts from sprayingization.Application No. is 201710295021.4 patented inventions one kind to rub
Motorcycle body is cladded with part bloom and exempts from the alloy material that paints, and the material is by the components structure such as ABS resin, PC resin, toner, pearl mica
At, have many advantages, such as that higher gloss degree, wearability are good, intensity is high, heat distortion temperature is high, without colouring, spray painting etc. processing steps.
But will be greatly reduced the processing performance of material using inorganic pearl mica powder, material melt mobility is low.And nothing
Machine pearl mica powder and the compatibility of most of organic polymer matrixes are often poor, need to use other in the upper past contact of processing preparation
Mutual infiltration degree and compatibility of the means (chemical modification, addition compatilizer etc.) between Lai Tisheng inorganic phase and organic phase.
