Problems solved by technology

[0004] However, domestic masterbatch products have a single structure and incomplete varieties, and general-purpose products account for a large proportion. When plastics need to be colored, single-color masterbatches are used for coloring. When antistatic performance is required, antistatic masterbatches are added. When flame retardant performance is required Add flame retardant masterbatch
The method of adding a single masterbatch makes it necessary to add a variety o...

Embodiment

[0034] A high-weather-resistant PVC color masterbatch is made of the following raw materials in parts by weight:

[0035] 40 parts of polyvinyl chloride resin, 20 parts of inorganic pigment, 10 parts of fiber, 2 parts of composite dispersant, 2 parts of ultraviolet absorber, 2 parts of antioxidant, 1 part of reinforcing agent.

[0036] The inorganic pigment is pigment red.

[0037] The fiber is composed of bamboo charcoal fiber and coconut charcoal fiber in a mass ratio of 2:1.

[0038] The composite dispersant is prepared from dispersant YY-5023, maleic anhydride grafted polyethylene wax, and polycarboxylate sodium salt dispersant in a mass ratio of 2:2:1.

[0039] The ultraviolet absorber is composed of phenyl o-hydroxybenzoate and 2-hydroxy-4-methoxybenzophenone in a mass ratio of 1:1.

[0040] Described antioxidant is antioxidant 1010, triethylene glycol bis-3-(3-tert-butyl-4-hydroxyl-5-methylphenyl) propene, three (2,4-di-tert-butylphenol ) Phosphite is composed of 2:1...

Abstract

The invention discloses a high weatherability PVC (Polyvinyl Chloride) color masterbatch. The high weatherability PVC color masterbatch is prepared from the following raw materials: 40 to 60 parts ofpolyvinyl chloride resin, 20 to 30 parts of inorganic pigment, 10 to 15 parts of fibers, 2 to 3 parts of a compound dispersant, 2 to 3 parts of an ultraviolet light absorber, 2 to 3 parts of an antioxidant and 1 to 2 parts of a fortifier. The PVC color masterbatch provided by the invention has the advantages of reasonable formula, high weatherability, excellent wear resistance, easiness in dispersion, low cost and simple preparation process. When being applied to the coloring of PVC products, the PVC color masterbatch has the advantages of lower dosage, higher colorant concentration, high utilization rate, high antibacterial property, good weatherability, uniform coloring, no discoloration and no effect on mechanical properties of the PVC products; the service life of the PVC products is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-weather-resistant PVC color masterbatch and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC for short) is a non-toxic, odorless white powder. Domestic production and consumption of PVC rank first among the five general-purpose resins. PVC products have the advantages of chemical resistance, flame self-extinguishing, wear resistance, noise reduction and shock absorption, high strength, good electrical insulation, low price, wide source of materials, and good air tightness. They are used in industry, construction, Agriculture, electric power, public utilities and other fields have broad application space. However, PVC has poor thermal stability, and is prone to aging, discoloration, cracking, brittleness or pulverization under the action of light, heat and oxygen, and loses its mechanical properties. [0003] At pr...
