Description
Technical field
The present invention relates to a kind of color concentrate, particularly, the present invention relates to a kind of carrier of liquid polymers as a kind of tinting material for the masterbatch as the painted polyester article of preparation that use, more specifically, the present invention relates to a kind of liquid color concentrate for polyester article.
Background technology
In various industry, plastics have replaced other materials.In packaging industry, plastics instead of glass minimize breakage, weight reduction, and reduce the energy expenditure in manufacturing and transporting.In other industry, plastics substituted metal minimize corrosion, weight reduction, and integral colouring product is provided.
Attract human consumer to go the container of buying individual size or family's size to comprise trade mark and commodity packaging.In these elements, valuable commodity packaging is the color of container.And above-mentioned color can need with translucent, transparent, or other special-effects for bottle depositing.
Liquid colourant is just being widely used for pigmented polyester (for example polyethylene terephthalate or PET or PC) goods, for example beverage bottle.Many application in PC are light, have extremely low colorant content.In many light color application, this carrier system produces has low viscous liquid dispersion.Lamentedly, have low viscous liquid product and have a kind of not long storage life, because tinting material trend deposition, this may cause the misalignment in the time of blowing PC bottle.
In order to overcome the problem of storage life, conventionally in liquid color concentrate, add the thickening material based on silicon oxide to increase viscosity.But these silica-based thickening materials are difficult to processing, and become very difficult in the control of course of processing medium viscosity.
CN101802051 discloses a kind of liquid color concentrate, and it contains a kind of polyalkylene polyvalent alcohol carrier; Tinting material; With other optional functional additive.Described tinting material can be one or more pigment, one or more dyestuffs, or its mixture.Described liquid color concentrate and poly terephthalic acid alkyl diester resin compatible, be used in particular for manufacturing painted polyester beverage bottle and other polyester article.
