Abstract

The invention discloses novel PVC (polyvinyl chloride) inorganic pigment paste and a preparation method thereof. The PVC inorganic pigment paste comprises 125-130 parts of an inorganic pigment, 80 parts of epoxidized soybean oil, 20-25 parts of dioctyl terephthalate, 20-25 parts of chlorinated n-alkane, 5-7 parts of PVC resin, 1.2-1.5 parts of a toner, 1.2-1.5 parts of a dispersing agent, 0.8-1 part of a dispersing aid and 169.5-175 parts of heavy calcium carbonate; then the PVC inorganic pigment paste is obtained through steps of mixing, heating, stirring and grinding. The PVC inorganic pigment paste is brighter in luster, free of layering and low-temperature-resistant, cannot crystallize easily, and has characteristics of capability of increasing the luster, resisting settling and resisting freezing.

Description

technical field

[0001] The invention belongs to the field of inorganic pigment color paste, and in particular relates to a novel polyvinyl chloride inorganic pigment color paste and a preparation method thereof. Background technique

[0002] Polyvinyl chloride color paste (PVC color paste) is divided into two categories: PVC organic color paste and PVC inorganic color paste, both of which have their own advantages and disadvantages. The main advantages of PVC organic color paste are bright colors and good transparency; the disadvantage is that products with higher physical properties have higher prices, and there is no cost advantage. In addition, similar products produced by different manufacturers have great differences in physical properties in terms of hue, concentration, migration, and weather resistance. The advantage of PVC inorganic color paste is that all series of products have good weather resistance, migration resistance, light resistance, high hiding power, and...

Examples

preparation example Construction

[0060] The preparation method of described kind of novel polyvinyl chloride inorganic pigment color paste, comprises the following steps:

[0061] By weight, weigh each component;

[0062] 1) Mixing: Mix 15 parts of epoxidized soybean oil and high-polymerization polyvinyl chloride resin, stir at a speed of 1200-1500r / min for 12-20min, then filter with a 160-mesh filter to obtain mixture H;

[0063] 2) Heating: Add 50 parts of epoxidized soybean oil and dioctyl terephthalate into the stainless steel heating mixing tank, after heating to 120-130°C, slowly pour the mixture H into the heating mixing tank, and use 1300- Stir at a speed of 1500r / min for 12-20min, then stand still for 12-15h to obtain the mixture R;

[0064] 3) Stirring: Add the remaining epoxidized soybean oil, chlorinated n-alkane, color enhancer, dispersant and dispersing aid to the mixture R, stir at a speed of 1500-1800r / min for 10-15min, then adjust the speed to 600-800r / min, slowly add inorganic pi...
