Description
Technical field
The present invention relates to a kind of liquid color concentrate, particularly, the liquid polymers that the present invention relates to acrylic amide is the application for the preparation of the colour batch of painted plastics as the carrier of tinting material.
Background technology
In various industry, plastics have substituted other material.In packaging industry, plastics are instead of glass, thereby has farthest reduced breakage, has alleviated weight, and has reduced the energy consuming in manufacture and transport.In other industry, plastics have substituted metal, thereby have farthest reduced corrosion, have alleviated weight, and overall colored product is provided.
Attract the applicable individual of human consumer's purchase or the container of whole family's use to comprise trade mark and exterior of commodity.In the key element of valuable exterior of commodity, comprise the color of container.And this color may need to combine with other special-effect of translucency, the transparency or this bottle.
Liquid color concentrate is to form free flowable predispersion with the pigment of carrier format, and carrier and processed matrix resin are compatible.
The carrier system of existing liquid color concentrate utilization based on tensio-active agent, oil and/or softening agent.These products are conventionally incompatible with many polymkeric substance, and result causes the forfeiture of physical properties, causes the processing problems of screw slippage and so on.The transparency of the optically transparent polymkeric substance of many existing carriers affect, for example polycarbonate of these polymkeric substance (PC), polymethylmethacrylate (PMMA), styrene-acrylonitrile (SAN).Therefore, liquid color concentrate and these plastic resins are not used jointly.
And existing colour batch carrier has limited thermostability, can not be used for making the polymkeric substance colouring of PC processing at approximately 600 ℉ (315 DEG C) and so on.
At present, use the resin of particle primary color master batch and precolor.But this application still faces some problems.Particle primary color master batch for tint applications uses the in the situation that of high dilution or " subtracting dense (letdown) " ratio, to obtain good color distribution.The manufacture of the resin of precolor and inventory cost are very high.This resinoid also experiences two thermal processs (being first compounding process, is then moulding process), and this may be harmful to some polymkeric substance.
CN101421348B provides a kind of liquid color concentrate, the functional additive that this liquid color concentrate comprises acrylic acid or the like liquid polymers carrier, tinting material and optional other.Tinting material can be one or more pigment, one or more dyestuffs or their combination.This liquid polymers is compatible with various plastic resin, especially optically transparent plastic resin, for example polycarbonate, polymethylmethacrylate and styrene-acrylonitrile.But, in prior art, colour batch to be carried out after modification resin, its thermostability variation, has affected the over-all properties of resin.
