Environmental protection PVC color cake

Abstract

The invention relates to an environmental protection PVC color cake. The environmental protection PVC color cake comprises 38 to 45 parts of PVC paste resin, 33 to 42 parts of PVC resin powder, 28 to35 parts of poly amino resin, 32 to 39 parts of a pigment, 20 to 32 parts of diatomite, 8 to 13 parts of zinc stearate, 12 to 16 parts of stearic acid, 6 to 11 parts of nanometer zinc oxide, 3 to 6 parts of organic tin, 2 to 5 parts of organic antimony, 11 to 15 parts of epoxy soybean oil, 6 to 12 parts of cellulose, 4 to 9 parts of silica, 30 to 45 parts of deionized water, and 16 to 23 parts ofglycerin. Novel materials are added into an obtained base material, and dispersion grinding is carried out so as to obtain the environmental protection PVC color cake. The environmental protection PVCcolor cake is prepared from the novel environment-friendly materials at a scientific and reasonable ratio, the common environment-friendly safe raw materials are adopted in the formula, so that the obtained environmental protection PVC color cake is high in safety, uniform in coloring, low in manufacturing cost, and excellent in application potential, is convenient to use, and is economical.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride environment-friendly materials, in particular to an environment-friendly PVC color cake. Background technique [0002] Color cake is a high-concentration mixture prepared from resin and a large amount of pigment or dye. When processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the coloring resin or product with pigment concentration. Color cake is widely used in polychlorinated Ethylene, polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET and other resins can be used to produce colorful fibers, wires and cables, household appliances, agricultural films, auto parts, health care equipment and other products. [0003] Chinese patent application CN104004300A discloses a masterbatch formula, including 75-85% carrier, 5-6% additive, 3-5% dispersant, 2-3% pearl powder, 1-2% pigment, 1-2% organic ester 2%, 3-5% paraffin, wherein the pigments ...

Problems solved by technology

[0003] Chinese patent application CN104004300A discloses a masterbatch formula, including 75-85% carrier, 5-6% additive, 3-5% dispersant, 2-3% pearl powder, 1-2% pigment, 1-2% organic ester 2%, 3-5% paraffin, wherein the pigments are phthalocyanine red, phthalocyanine basket, phthalocyanine green, sunfast red, macromolecular red, macromolecular yellow, permanent yellow, permanent red, azo red One or several kinds of mixtures, the color masterbatch has many colors, good gloss, and strong controllability, but the permanent yellow in the color masterbatch is not resistant to high temperature, and it is easy to change color during processing. Affect the normal color of the product

[0004] At present, the color masterbatches on the market have the problem that the color difference is difficult to control, the color difference between batches is large, and it is difficult to meet the requirements of customers. In practice, the color difference control of the color cake itself is the key. It is the measure of color and the manufacturer. The primary indicator of product quality level, in actual production, the color difference is usually manifested in the color difference between the color cake sample and the color cake required by the customer, the color difference between the color cake sample and the mass order product, the color difference between the color cake supply batches, the basic The color difference after the material variety and brand change, etc., and the color cake materials used in the prior art contain benzene substances, which greatly limits the use of color cakes, and pollution hazards will also become a problem in the promotion of color cakes
